DETAILED DESCRIPTION

[0185] In relation to the figures described below, where the present disclosure may be described with reference to various embodiments, without limiting the same, it is to be understood that the disclosed embodiments are merely illustrative of the present disclosure that may be embodied in various and alternative forms. The figures may not be to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for e.g. teaching one skilled in the art to variously employ the present disclosure.

[0186] FIG. 1a illustrates schematically a trim profile 1 according to an embodiment of the present disclosure, seen in perspective and towards an end of the profile, and FIG. 1b illustrates the same profile seen from above towards a bend 10. The trim profile 1 comprises a plurality of bends extending in the longitudinal direction LD of the trim profile 1. These bends comprises a first bend 10 providing an elongated crest/ridge 16, and one or more second bends 20 placed between the first bend 10 and one of the side edges 2a, 2b of the trim profile. Hence, the bends 10, 20a, 20b are arranged between side edges 2a, 2b of the profile 1, which extends in the longitudinal direction LD of the trim profile. Thereby, the bends shapes an interior surface 11 and an exterior surface 12 of the trim profile 1. The exterior surface comprises one or more convex surfaces due to the bends 10, 20a, 20b, whereas the interior surface comprises one or more concave surfaces provided by the bends 10, 20a, 20b.

[0187] In FIG. 1, the trim profile 1 has a C-shape seen in in cross section (in a plane extending transverse and perpendicular to the longitudinal direction LS), where the C-shape is provided by the first bend and further bends 20a, 20b.

[0188] The bends 10, 20a, 20b of the trim profile 1 provides elongated wall parts extending in the longitudinal direction LD of the trim profile. These elongated wall parts comprises a first wall part 6 extending between the first bend 10 and a second bend 20a, and furthermore a second wall part 7 arranged between the first bend 10 and a further second bend of the trim profile. Additionally, the trim profile 1 comprises a third wall 5 part extending between the second bend (20a) and a first side edge (2a), and a fourth wall part 8 extending between the other side edge 2b and the further second bend 20b, The second bends 20a, 20b hence extends between the first bend 10 and the respective side edges 2a, 2b of the trim profile 1.

[0189] In FIG. 1, the exterior surface 12 at the “vertex” of the bends 20a, 20b provides the largest width W of the profile, Moreover, in FIG. 1, the maximum height H of the profile is defined between the “vertex” of the first bend 19 at the exterior surface 12, and towards and perpendicular to an envisaged bottom line BL drawn between the edges 2a, 2b of the profile.

[0190] At least one of the bends 10, 20a, 20b, such as the first bend 10 as illustrated in FIG. 1 may provide a first wall part 6 and a second wall part 7 with a bend angle there between. The bend angle a1 between the first and second wall parts 6, 7 may in embodiments of the present disclosure be between 45° and 150°, such as between 85° and 130°, for example between 100° and 120°. The same may apply for one or both second bends 20a, 20b in further embodiments of the present disclosure.

[0191] In embodiments of the present disclosure, the width W of the trim profile 1 may be between 2 mm and 50 mm, such as between 3 mm and 20 mm, such as between 4 mm and 15 mm.

[0192] In embodiments of the present disclosure, the height H of the trim profile 1 may be between 2 mm and 50 mm, such as between 3 mm and 20 mm, such as between 4 mm and 15 mm.

[0193] In preferred embodiments of the present disclosure, the trim profile is made from a metal plate material in the form of a steel material such as a stainless steel material, for example a chromium-nickel stainless steel material. In embodiments of the present disclosure, the steel material comprises at least 12% by weight of chrome (Cr).

[0194] For example, the steel material of the profile 1 may in embodiments of the present disclosure be a SUS 304 (Japanese Industrial Standards (JIN)) grade steel or a SUS 304L grade steel. In certain embodiments of the present disclosure, the steel may be a 1.4301/AISI 304/X5CrNi18-10 stainless steel. Even though the trim profile may preferably be a steel, such as a stainless steel profile, the metal profile may also be made from a metal of another material than steel, e.g. aluminium, brass or copper or other metals or metal alloys, in other aspects of the present disclosure.

[0195] The material of the trim profile 1 has a wall thickness between 0.2 mm and 1.0 mm such as between 0.3 mm and 0.8 mm, preferably between 0.4 mm and 0.6 mm. For example, in some embodiments, the wall thickness of the trim profile material may be about 0.5 mm. This wall thickness is defined between the interior and exterior surfaces 11, 12.

[0196] The material of the trim profile 1 may in other embodiments of the present disclosure a wall thickness between 0.2 mm and 3 mm such as between 0.3 mm and 1.5 mm.

[0197] This may e.g. be relevant if the trim profile material is aluminium alloy material or another material softer than stainless steel, but it may also apply for stainless steel profiles.

[0198] The bends 10, 12a, 12 may preferably have been made by means of roll forming. Alternatively, the trim profile 1 may be a trim profile that has been extruded and/or pultruded in order to provide the shape with the bends 10, 20a, 20b.

[0199] In FIG. 1 a, a dash/dotted bending line 4 is illustrated. This line represents a location where an end wall is desired to be provided on the trim profile 1.

[0200] It is generally understood that the trim profile after manufacturing according to embodiments of the present disclosure may be used for decorative metal trim profiles for vehicles, such as four wheeled vehicles, e.g. cars, trucks or the like, or vessels such as boats, or in any other suitable usage such as for example as decorative elongated trim profiles for building parts or furniture. The decorative trim profiles may be decorative in the sense that they are visually aesthetically appealing to the eye, that is, they may be substantially evenly smooth and shiny, and even reflective, as is e.g. commonly employed for window trims in the automotive industry, such as for a two- and/or four-wheeled automotive.

[0201] FIG. 2 illustrates an embodiment of the present disclosure where a cut-out operation has been provided before shaping an end wall part on the profile 1.

[0202] The trim profile 1 comprises a first elongated part 40a that is to be used for the final trim profile, and a second part 40b that used for shaping and providing the end cap/end wall 30 (see figures described below) on the trim profile. The line 4 provides the border between the first and second parts 40a, 40b.

[0203] Prior to shaping the end wall, a cut out operation may be provided where a cut out 3 is provided at the second bend(s) 20a, 20b in the end wall area 13 of the second part 40b in order to remove at least a part of the trim profile material at the one or more second bends 20a, 20b.

[0204] In embodiments of the present disclosure, cut out 3 may have a length LC that is between 0.2 and 3 times, such as between 0.5 and 1.5 times the height H of the trim profile 1. In embodiments of the present disclosure, cut out 3 may have a length LC which is larger than 0.2 times the height of the trim profile, such as larger than 0.5 and times the height H of the trim profile 1. In other embodiments, the cut out(s) 3 may possibly be omitted.

[0205] The cut outs 3 are provided in order to remove the walls 5, 8 in the area, and may also as illustrated extend at least partly into the walls 6, 7. However, in other embodiments, the cut outs 3 may be provided in order to remove the walls 5, 8 and the bends 20a, 20b alone.

[0206] As can be seen especially at FIG. 1, the bends 10, 20a, 20b extending in the longitudinal direction LD of the trim profile provides an interior space 14 in the elongated profile 1, where at least two, such as at least three, for example at least four walls 5, 6, 7, 8 of the trim profile extending in the longitudinal direction encloses the interior space 14. In the example of FIG. 1, the four walls 5-8 provides the interior space 14. The cross sectional area of the interior space 14 determined between the walls and enclosed by an envisaged bottom line BL drawn between the side edges 2a, 2b of the profile extending in the longitudinal direction may in embodiments of the present disclosure be between 0.5 cm.sup.2 and 8 cm.sup.2, such as between 0.5 cm.sup.2 and 5 cm.sup.2, for example between 1 cm.sup.2 and 4 cm.sup.2

[0207] FIG. 3 illustrates schematically an embodiment of the present disclosure wherein the trim profile 1 (seen from the side) is placed in a deep drawing arrangement according to embodiments of the present disclosure.

[0208] The deep drawing arrangement comprises a first fixation arrangement 100 and a second fixation arrangement 200. The part 40a of the trim profile is arranged in the first fixation arrangement 100, and the part 40b of the trim profile is arranged in the second fixation arrangement 200.

[0209] A working space 310 is provided between the first and second fixation arrangements 100, 200, and a stamp 300 is configured to be displaced into the working space. The working space is arranged opposite to a surface 114 of an interior support part 110 of the first fixation arrangement 100, which will face the end wall part 30a during the deep drawing operation.

[0210] FIG. 3a illustrates a cross section of the first fixation arrangement trough the view “A-A” illustrated in FIG. 3, and FIG. 3b illustrates an exploded view of FIG. 3a where fixation arrangement and trim profile 1 are separated.

[0211] The fixation arrangement 100 illustrated in FIGS. 3, 3a and 3b comprises an interior support part 110 arranged in the interior space 14 of the trim profile which is enclosed by the interior surface 11. The interior support part 110 comprises a support surface 111 shaped to follow, abut and support the interior surface 11 of the trim profile 1. The fixation arrangement 100 moreover comprises an exterior support part 120 arranged at the exterior surface 12. The exterior support part 120 comprises a support surface 121 shaped to support and abut the exterior surface 12 the elongated metal trim profile during a subsequent deep drawing operation in order to provide an end wall on the profile in the area of the bend line 4.

[0212] The first part 40a of the trim profile is arranged and held between the interior support part 110 and the exterior support part 120.

[0213] The support surface 111 of the interior support part 110 comprises a ridge 112 configured to extend into the concavely shaped recess/valley of the interior surface 11 of the trim profile which is shaped by the bend 10. This ridge 112 extends in the longitudinal direction LD of the trim profile 1 and comprises a surface curvature that substantially matches the internal surface curvature at the bend 10 at the interior surface 11. Hence, the trim profile material at the bend 10 supports on the ridge 112 of the interior support part. The remaining part of the interior support part 110 supports the walls 6, 7 of the trim profile.

[0214] The exterior support part 120 comprises a support/counter hold surface 121. This surface comprises a recessed portion 122 in the support surface 121 into which the bend 10 of the trim profile extends. Hence, the exterior surface 12 of the trim at the location of the ridge extends into the recessed portion 122, and the remaining part of the exterior support part 120 supports on the walls 6, 7 of the trim profile. Hence the trim profile remain the desired shape provided by the bends in the longitudinal direction of the trim profile, which substantially is the final shape of the trim profile, while it is supported between the support parts 120, 110.

[0215] A fixation arrangement control device 123 illustrated in FIG. 3a may be configured to control the distance between the support surfaces 111, 121 of the support parts 110, 120 and e.g. also control the force with which the support surfaces 111, 121 presses towards the profile 1 in order to fixate and possibly clamp the fixation profile 1 between the support parts during a subsequent deep drawing operation as described further below. The fixation arrangement control device 123 may e.g. be an adjustable spring arrangement or an active control device such as a controllable linear actuator such as an electric actuator or the like, or a combination thereof.

[0216] The second fixation arrangement 200 may be substantially similar in design to the first fixation arrangement 100 and may accordingly comprises support parts 220, 210 which are shaped and arranged in a similar way as the parts 110, 120 of the fixation arrangement. A further fixation arrangement control device (not illustrated) may be configured to control the second fixation arrangement.

[0217] As can be seen, the cut out 3 (if present) may be placed opposite to the working

[0218] FIG. 4 also illustrates an embodiment of the present disclosure, where a further cut out 15 (also referred to as a further cut out in the present document) is provided in the part 40a, see also FIG. 3b and FIG. 8. This further cut out 15 is provided in the lower part of the profile 1 and removes at least a part, if not all of the wall material of the walls 5, 8. This provides that the interior support part can be removed after the deep drawing process. The further cut out 15 starts at a position 15a at the part 40a and extends here from the end wall parts 5, 8 that are not removed at the part 40a, and to the cut out 3, which in embodiments of the present disclosure may have removed more material and hence extend into the wall parts 6, 7.

[0219] FIG. 4. Illustrates schematically a deep drawing operation seen in a cross sectional view in the longitudinal direction of the trim profile 1 according to embodiments of the present disclosure. When the trim profile 1 has been arranged properly in the fixation arrangements 100, 200, a deep drawing operation is provided by providing a relative displacement between a stamping tool 300 and the first and second fixation arrangements 100, 200 in a direction transverse to the longitudinal direction LD of the trim profile 1. Hereby the stamping tool 300 moves into the working space 310, and deforms the trim profile material in the end wall area 13 into the working space. The deep drawing operation thereby provides an end wall part 30a on the trim profile.

[0220] The relative displacement during the deep drawing operation in order to bring the stamping tool into the working space 310 and deform the trim profile to provide the end wall part 30a is preferably provided by keeping the first and second fixation arrangements 100, 200 in a fixed position and moving the stamping tool 300 into the working space. However, in other embodiments, the first and second fixation arrangements 100, 200 may be moved while keeping the stamping tool fixed. In still further embodiments, the first and second fixation arrangements 100, 200 may be moved in a first direction transverse to the longitudinal direction LD while the stamping tool is also moved in the opposite direction opposite to the longitudinal direction.

[0221] In FIG. 4, a driver device 320, such as a motor, e.g. an electric motor such as a servo motor (which may be preferred) or a stepper motor, provides the displacement of the stamping tool 300 into the working space 310 by operating an actuator 330, such as a linear actuator, for example a spindle drive connecting the driver device 320 and the stamping tool 300.

[0222] The stamping tool 300 may, dependent on the shape of the contact surface of the stamping tool which is pressed towards the trim profile material to provide the deep drawing, start the deep drawing operation by abutting and deforming the upper ridge of the trim profile which is provided by the bend 10 extending in the longitudinal direction (LD) of the trim profile as e.g. described previously.

[0223] The deep drawing hence provide a drawing of the trim profile 1 metal sheet material and may hence make the end wall 30a part material thinner Th2 than the general/initial material thickness Th1 of the trim profile, while the remaining part of the trim profile such as the elongated walls 5-8 that are present on the trim profile at the part 40a remains the initial sheet thickness Th1. In return, the end wall part 30a is formed which extends in a direction different from the longitudinal direction LD of the trim profile, and which so to say closes off the end of the trim profile part 40a and covers the interior space 14 of the trim profile.

[0224] As can be seen in FIG. 4, the interior support part 110 comprises a corner part/corner support portion 113 that defines the internal bending radius r1 of the corner bend provided between the part 40a and the end wall part 30a when the deep drawing operation is provided. The inner bending radius r1 at the end wall 30, which is provided due to the deep drawing operation may in embodiments of the present disclosure be below 3 mm, such as below 2 mm, for example below 1.5 mm. The bending radius r1 provided by the deep drawing operation may substantially be the desired bending radius at the final trim, or may be adapted a little after the deep drawing operation in a further processing step.

[0225] In embodiments of the present disclosure, the inner radius r1 may, after the deep drawing operation and provided by the deep drawing operation may be below 1 mm, such as below 0.8 mm or below 0.6 mm.

[0226] Generally in embodiments of the present disclosure, the inner radius after the deep drawing operation and provided by the deep drawing operation may be between 0.2 mm and 5 mm, such as between 0.2 mm and 3 mm, for example between 0.3 mm and 2 mm.

[0227] The deep drawing operation stretches the metal wall of the trim profile at and/or near the end wall. This may as illustrated provide that the wall thickness of an area (34—see FIG. 5) of the end wall part 30a (and at the final end wall) may be at least 10%, such as at least 20%, for example at least 30% lower than the general material thickness (th2) of the trim profile. This area with the thinner sheet material thickness is located at the plane wall part of the end wall part 30a such as at a centre part of the end wall as illustrated in FIG. 5. For example, at least 20% such as at least 30% e.g. at least 40% of the end wall part may have a wall thickness Th2 that is lower than the initial wall thickness th1 of the trim profile before the deep drawing operation.

[0228] The deep drawing operation provides a draw length DL by means of the stamping tool 300. This draw length DL is determined by the largest draw length provided at the trim profile 1 in order to deform the trim profile at the part 40b and thereby obtain the end cap part 30a. This draw length may be at least 5 mm, such as at least 9 mm, for example at least 13 mm. The draw length DL may in embodiments of the present disclosure be between 5 mm and 30 mm, such as between 9 mm and 20 mm, for example between 13 mm and 18 mm.

[0229] The bend angle a2 (referred to as “bend angle” even though it is obtained by the deep drawing) between the end wall part 30a and the walls 6, 7 and the recess in the interior surface 11 provided by the bend 10, which is provided by the deep drawing operation, may in embodiments of the present disclosure be between 60° and 120°, such as between 70° and 105°, for example between 85° and 95°, e.g. such as 90°±2°. This angle a2 may be defined by the movement direction and/or shape of the stamping tool 300.

[0230] In embodiments of the present disclosure, the first fixation arrangement 100 provides a tighter grip and hold on the first part 40a that is to be used for the final trim, than the second fixation arrangement 200 holds/fixates the second part 40b.

[0231] Hence, during the deep drawing process, the second fixation arrangement may allow a part of the trim profile material between the parts 220, 210 to slide/move into the working space due to the forced provided by the tool 300 on the trim profile material. However, less material may be allowed to slide between the parts 110, 120 of the first fixation arrangement during the deep drawing operation.

[0232] In certain embodiments of the present disclosure, the first fixation arrangement may provide a firm grip on the trim profile part 40a so that substantially no sliding of the trim profile part 40a material between the holding parts 110, 120 in the longitudinal direction LD of the trim profile is provided during the deep drawing operation.

[0233] The stamping tool 300 has a length TL extending in the longitudinal direction LD of the trim profile 1 between the tool ends 300a, 300b. The length TL may in embodiments of the present disclosure be between 5 mm and 40 mm, such as between 10 mm and 30 mm, for example between 20 mm and 30 mm. The lower the length TL, the less of the material 40b may become excess material and thus subsequently scrapped after the deep drawing operation, and hence utilization of the trim profile 1 may be increased.

[0234] FIGS. 4a-4b illustrates, seen through a cross sectional plane that extends perpendicular to the longitudinal direction of the trim profile, various embodiments of the stamping tool surface 301 of the stamping tool 300 which may be used for deforming the trim profile during the deep draw operation according to embodiments of the present disclosure. In FIG. 4a, the stamping surface 301 of the tool 300 is substantially straight and will initiate the pressing on the crest 16 during the deep drawing operation. In FIG. 4b the surface 301 comprises a recess 301 shaped to receive the crest 16 and is divided into two parts, the first part comprising the recessed portion 301 and a second part 301b which is not shaped to accommodate the curvature of the surface 12. In further embodiments of the present disclosure (not illustrated but envisaged as seeing through a plane as in FIGS. 4a and 4b), the surface 301 may be convexly shaped and may have a top point that may initially start to provide a deformation of the crest 10 at initiation of the deep drawing operation.

[0235] FIG. 4 moreover illustrates a further curvature radius of the corner radius r2 of the stamping tool 300 according to further embodiments of the present disclosure. The corner radius is the radius at the corner of the tool 300 in the transition between the stamping surface 301 and the end surface 300b. The radius r2 may preferably be larger than 5 mm such s larger than 10 mm, or even larger such as larger than 15 or larger than 20 mm. In embodiments of the present disclosure, the radius r2 may be so large that substantially the entire stamping surface 310 is curved between the ends 300a, 300b and thus provides a convex surface.

[0236] FIG. 5 illustrates in perspective a view towards an end wall/end cap 30 provided at the final trim profile of the trim profile part 40a. Here, the end wall 30 has a height DLx that has been provided by the deep drawing operation. The height DLx has a lenth that is equal to or less than the draw length DL provided by the deep drawing operation.

[0237] The height DLx may be larger than (e.g. at least 3% such as at least 5% larger) than the height H (see FIG. 1) of the trim profile, and hence the draw length DL (see FIG. 4) may be larger than the height H of the trim profile.

[0238] As can be seen from FIG. 5, the end wall 30 of the final profile has been separated from the excess material provided during the deep drawing operation and has been cut into a desired shape, in the present example a rhombus shape, but it may also be cut into e.g. a rectangular or triangular shape dependent on which shape is desired.

[0239] FIG. 6 illustrates another embodiment of a trim profile according to embodiments of the present disclosure where the trim profile has another shape, and where the end wall has been provided by a deep drawing operation as previously disclosed. This shape may be suitable for e.g. upper 50a window trims on e.g. doors of a vehicle (see FIG. 13).

[0240] The trim profile illustrated in FIG. 5 (see also FIGS. 1 and la) may be suitable for lower window trims—see FIGS. 13-50b. The lower trim profile 50b may in some situations be more complex to provide a suitable end wall solution on as the shape of the profile must be visually pleasing and at the same time the trim 50b design may need to comprise and/or support one or more sealing solutions in order to obtain a suitable sealing, and possibly also dew removal, between a vehicle window that can be displaced to an open and closed position in a vehicle door relative to the trim profile 50b.

[0241] FIG. 7 illustrates schematically and in perspective a further embodiment of a trim profile 1 on which an end wall/end cap may be provided by means of a manufacturing process including the deep drawing operation as described above according to embodiments of the present disclosure. This profile is substantially similar to the profile illustrated in FIG. 1, though where the wall 5 has been omitted.

[0242] FIG. 8 illustrates an embodiment of the present disclosure where the end wall 30 part is further processed in order to obtain a desired surface and/or shape. Here, an end wall processing device 60 such as a rotating wheel as illustrated is used for processing such as roller shaping, grinding and/or polishing on the exterior surface of the end wall 30. The processing device 60 is pressed against the exterior surface of the end wall 30 with a force F1, and an interior end wall support 61 is arranged in the interior of the profile in order to support the end wall and provide a counter force to the force F1 from the device 60. The interior end wall support 61 comprises hence an end wall support surface 62 arranged with an angle relative to the longitudinal direction LD of the trim profile 1, and thereby to ensure that the end wall 30 is either supported at the initial desired angle, or maintained at the desired angle after the force F1 has been provided.

[0243] The end wall processing device 60 may in preferred embodiments be moved relative to the trim profile 1 from the bended corner 31 of the end wall 30 and towards the edge of the end wall opposite the corner 31. Preferably, the device 60 may be moved from the ridge provided by the bend 10 and toward the lower edge 32 of the end wall 30 in the processing direction PRD where the surface of the end wall is processed by the end wall processing device 60. Even though the end wall processing device is illustrated as being a rotating wheel in FIG. 10, it is understood that the processing device may also e.g. be a plate another type of processing device arranged to be slided/displaced over the surface of the end wall to provide a treatment of the end wall part surface.

[0244] FIG. 9 illustrates schematically an embodiment of the present disclosure relating to the deep drawing operation wherein the speed DSP with which the stamping tool 300 is displaced is regulated during the deep drawing operation.

[0245] The displacement speed DSP of the tool 300 is in FIG. 9 changed during the deep drawing operation between the initial position IPOS where the deep drawing is initiated and starts to deform the trim profile 1, and the end position EPOS position where the deep drawing operation is ended. These two positions IPOS, EPOS defines the draw length DL extending there between as previously described.

[0246] Varying the displacement speed DSP of the tool 300 may help to ensure a successful deep drawing operation in order to obtain an end wall part of sufficient quality, also in thinner material such as steel material, e.g. stainless steel material, having a wall thickness between 0.2 mm and 1.0 mm such as between 0.3 mm and 0.8 mm, preferably between 0.4 mm and 0.6 mm.

[0247] The displacement speed DSP speed may in embodiments of the present disclosure be changed by e.g. reducing the speed of the tool 300 during the deep drawing process by e.g. providing a gradual reduction of the draw speed DSP1 from the initial position IPOS to the end position EPOS.

[0248] A control system 300 comprising control circuitry including a computer processor 331 and a data storage 332 provides the control by control signals 333 of the driver device 320 such as a servo motor, e.g. an electrical servo motor, for example a stepper motor or any other type of motor. The control system 330 operates according to a program code stored in the data storage 332 in order to provide a desired displacement speed profile of the tool 300 during the deep drawing operation. The driver device 320 or another sensor device may in embodiments of the present disclosure provide position feedback (not illustrated) to the control system, e.g. from one or more position sensors (not illustrated), in order for the control system to control the displacement of the tool 300. Though, such position feedback may also be omitted in other embodiments of the present disclosure, and the displacement speed may alone be controlled by a predetermined displacement profile program code stored in the data storage 332.

[0249] The acceleration of the displacement device from the initial position IPOS to the end position EPOS may in further embodiments of the present disclosure also be a control parameter that is regulated and changed by the control system 330 from the initial position IPOS to the end position EPOS based on a software program in the data storage.

[0250] FIGS. 10a-10e illustrates different embodiments of displacement speed profiles for the tool 300 according to embodiments of the present disclosure. Here, the displacement speed of the tool 300 is controlled by a controller 330 to be changed from the initial position IPOS to the end position EPOS according to the displacement speed profile.

[0251] This speed change may in embodiments of the present disclosure be provided based a predetermined speed profile that is dependent on the (present or predicted) position of the tool 300 during the deep drawing operation. This may be determined based on position information/data from an encoder of the like on the driver 320, or by counting steps if the driver 320 is a stepper motor. Additionally or alternatively, the displacement speed of the tool 300 may be controlled and varied based on input from one or more sensors (not illustrated) such as one or more force sensors arranged to determine directly or indirectly a force applied to the trim profile during the deep drawing operation to provide the end wall part 30a. The force sensor(s) may be a strain gauge sensor, or it may be a current monitor/sensor configured to detect/monitor the electrical current provided to the driver device 320, and the controller 330 may control the speed of the displacement of the tool 300 accordingly during the deep drawing process based on the input from the force sensor(s). As the electrical current consumed by the driver 320 will increase when increased force is applied, this current may indirectly be representative of the force applied. It is understood that any other suitable means for determining tool 300 position and/or force applied may be provided in further embodiments of the present disclosure.

[0252] In FIG. 10a, the displacement speed DSP of the tool 300 is reduced gradually from the initial position IPOS to the end position EPOS. In FIG. 10a, the tool reaches a point p1 where the speed DSP is kept substantially constant from that point and to the end position EPOS. Though, it is understood that the displacement speed DSP may also be reduced gradually all the way from the initial position IPOS to the end position EPOS.

[0253] In FIG. 10b, the displacement speed DSP of the drawing tool is also reduced gradually from the initial position IPOS to the end position EPOS. However in this embodiment, between the initial position IPOS and a first point p1, the displacement speed DSP is kept constant, between the first point p1 and the second point P2, the speed is gradually decreased, and from the second point p2 to the end position, the speed DSP is kept substantially constant from that point p2 and to the end position EPOS. Though the speed between p2 and the end position EPOS is substantially lower than the speed between the initial position IPOS and the first point p1 due to the speed reduction provided between the first point p1 and the second point p2.

[0254] FIG. 10c illustrates an embodiment of the present disclosure where a stepwise speed change is provided at certain points p1-p4 between the initial position IPOS and the end position EPOS. In FIG. 10c, the stepwise speed changes comprises a speed reduction at each point p1-p4. However, it may also in further embodiments of the present disclosure comprise a speed increase (not illustrated in FIG. 10c) between two consecutive points IPOS, p1 -p4, EPOS between the initial position IPOS and end position EPOS.

[0255] FIG. 10d illustrates an embodiment of the present disclosure where the speed change between the initial position IPOS and the end position EPOS is un-linear, and the gradient

[00001]$\left(\frac{d\mathrm{POS}\left(t\right)}{\mathrm{dt}}\right)$

of the displacement hence changes from the initial position IPOS to the end position EPOS. This may be controlled to be provided gradually or stepwise from the initial position IPOS to the end position EPOS.

[0256] FIG. 10e illustrates an embodiment of the present disclosure where the speed of the tool between the initial position IPOS and the end position EPOS both increases and decreases. This may e.g. help to provide certain desired characteristics of the trim profile material during the deep drawing operation from the initial position to the end position.

[0257] For several of the embodiments disclosed in FIGS. 10a-10e, the displacement speed DSP is reduced over time from the initial position IPOS to the end position EPOS.

[0258] FIG. 11 illustrates schematically an embodiment of the present disclosure wherein the second fixation arrangement 200 provides a displacement DIS2 transverse to the longitudinal direction of the trim profile 1 during the deep drawing operation. This may help to enable that more trim profile material may be available for the deep drawing operation in order to provide the end wall part 30a, as less stretching of the wall material may be needed near the second fixation arrangement as compared to the illustrated embodiment of FIG. 4. This may allow for a more firm and/or controlled grip on the trim profile by the second fixation arrangement 200. The second fixation arrangement 200 may here e.g. follow DISP2 the movement of the stamping tool and be displaced with a speed that is the lower or equal to the speed of the stamping tool. Also in FIG. 11, the working space 310 is arranged opposite to a surface 114 of an interior support part 110 of the first fixation arrangement 100, which will face the end wall part 30a during the deep drawing operation. The end 300b of the tool 300 faces the surface 114 during the deep drawing operation when the tool is in the working space.

[0259] FIG. 12 illustrates schematically an embodiment of the present disclosure wherein the second displacement arrangement 200 is moved DISP3 towards the working space 310 in order to reduce the stretching at a part of the trim profile material near the fixation arrangement. This movement DISP3 may be a movement controlled by a displacement arrangement (not illustrated) actively controlled by the control system 330 as previously explained, the fixation arrangement 200 may be connected to a passive spring or damper arrangement that provides a counterforce against the movement DISP3 and/or the like. Also in FIG. 12, the working space 310 is arranged opposite to a surface 114 of an interior support part 110 of the first fixation arrangement 100, which will face the end wall part 30a during the deep drawing operation.

[0260] In FIG. 4, the working space 310 is provided between the first and second fixation arrangements 100, 200, and between opposing walls 114, 214 of the interior support parts 210, 110 during substantially the entire deep drawing operation, and the same applies for the solution illustrated in FIG. 12. In FIG. 11, the working space 310 is defined between the walls 114, 214 of the first and second fixation arrangements 100, 200 before the deep drawing operation is initiated. For all three situations, the working space 310 is arranged opposite to a surface 114 of an interior support part 110 of the first fixation arrangement 100, which will face the end wall part 30a during the deep drawing operation.

[0261] FIG. 13 illustrates schematically a vehicle 51 seen from the side comprising trim profiles 50a, 50b provided according to embodiments the present disclosure. The deep drawing solution as disclosed according to the present disclosure may be suitable for providing end walls 30 on various designs of trim profiles, including upper and lower trim profiles 50a, 50b in window openings 54, and also on trim profiles having more complex cross sectional shapes and bend angles, such as bend angles a1 (see e.g. FIG. 1) between trim profile walls that is/are between 45° and 150°, such as between 85° and 130°, for example between 100° and 120°. Only a front door 52 at the vehicle in FIG. 13 is illustrated, but it is naturally understood that trim profiles 50a, 50b may also be provided at rear doors of the vehicle. Upper trim profiles 50a may here be arranged in continuation of each other (as illustrated), and the same may lower trim profiles 50b when the doors are closed. End walls of the trim profiles on the front door may thus be arranged to face end walls on trims on the rear door. If a rear door is absent, a trim profile with an end wall 30 may still be placed on the vehicle body.

[0262] FIG. 14 illustrates a photo of a stainless steel trim profile (as an intermediate product) that have been exposed to a deep drawing operation according to the present disclosure. The metal sheet material of the trim profile 1 is a stainless steel material having a thickness of about 0.5 mm. Here, it can be seen that an end wall part 30a has been formed and encloses the interior space of the trim profile. The profile used in FIG. 14 is substantially similar to the profile describe in relation to FIGS. 1 and 1 a. Excess material form the deep drawing process is still present in FIG. 15.

[0263] FIG. 15 illustrates a photo of the steel trim profile of FIG. 14 after a further processing of the end wall part and removal of excess material at the end wall in order to provide the final end wall 30. The trim profile 1 is here not further processed in order to obtain a desired surface coating at the exterior surface 12.

[0264] FIG. 16 illustrates a photo of a final finished trim profile provided by means of a manufacturing process including the deep drawing operation as described above. The trim profile 1 exterior surface 12 has been polished after the deep drawing process to provide the end wall part, and after the excess material has been separated from the end wall 30 and the lower end wall edges 32 have been shaped as desired and shown.

[0265] The end wall 30 here comprises lower edges 32 which was previously connected to the excess material. The trim profile depicted at FIG. 8 substantially corresponds to a trim profile made from a trim profile as illustrated in FIGS. 1 and 1 a, and processed into a trim profile as schematically illustrated in FIG. 5.

[0266] Instead of a chrome plated surface, the surface 12 may be painted with a paint or in other ways coated with a thin layer of material for decorative and/or protective purpose. The surface may naturally also be kept substantially uncoated, though this may increase the risk of the surface obtaining undesired scratches visible to the human eye.

[0267] In one or more examples of the present disclosure, the cut out 3 and/or the further cut out 15 may be provided in order to modify the material behaviour of the trim profile 1 during the deep drawing process and thus the quality of the final product. The material of the trim profile may undergo a more desirable structural and/or visual change by the present method, if the cut out(s) are provided proximate to the desired location of the corner 31 of the end wall 30.

[0268] Removing parts of one or more walls 5, 6, 7, 8 near the second bend(s) 20a, 20b, can allow for larger control of the behaviour of the material of the trim profile 1 during the deep drawing operation as less material will be present beneath and/or adjacent the desired location of corner 31 of the bend, thereby reducing the risk of material bulging, ridges and other disadvantageous effects in the final appearance of end wall 30 and the trim profile 1. Removing parts of one or more walls 5, 6, 7, 9 have shown to provide the effect of increased flow of material during the deep drawing process. Thus by careful selection of the shape, size and/or position of the cut-out(s) 3, 15 the direction and/or amount material flow can be controlled to provide the desired appearance of the final product. E.g. by having less material in the walls 5, 8 of the trim profile a larger flow of material along the longitudinal extent of the trim profile can be obtained. As a further example, the location of the cut out(s) 3, 15 can aid in determining from which side of the end wall area 13, and to what extent, material may flow into the working space 310 during the deep drawing process, which in turn provides an easy way of controlling the behaviour of the material and in turn the final product, such as the final material thickness of the end wall (30).

[0269] FIG. 17a and FIG. 17b relate to an embodiment of an interior support part 110, 210 of a fixation arrangement 100, 200, wherein the interior support part 110, 210 may be arranged in the interior space 14 of the trim profile, which is enclosed by the interior surface 11. The interior support part 110, 210 comprises a collective support surface 411 shaped to follow, abut and support the interior surface 11 of the trim profile 1 during a subsequent deep drawing operation in order to provide an end wall on the profile in the area of the bend line.

[0270] The collective support surface 411 of the interior support part 110, 210 comprises three discrete support elements 420, 430, 440 arranged to be movable relative to each other. A first discrete support element 420 comprises a ridge 412, which is arranged to be moved in and out of abutment with the trim profile 1 at the concavely shaped recess/valley of the interior surface 11 of the trim profile, which is shaped by the bend 10. This ridge 412 extends in the longitudinal direction LD of the trim profile 1 and comprises a surface curvature that substantially matches the internal surface curvature at the bend 10 at the interior surface 11. Hence, the trim profile material at the bend 10 supports on the ridge 412 of the interior support part.

[0271] A second support element 430 and third support element 440 are arranged on opposite sides of the first support element 420 and each comprises a protrusion 422, which is arranged to be movable in and out of abutment with the trim profile at the concavely shaped recess/valley of the interior surface 11 of the trim profile provided by a second bend 20a, 20b. The walls 6, 7 may be supported by the first, second and/or third discrete support element 420, 430, 440 preferably such that substantially entire interior surface 11 extending between the second bends 20a, 20b are supported by the interior support part 110, 210. Also the walls 5, 8 may be supported by the interior support part 110, 210 e.g. by the second and third support element 430, 440.

[0272] The first support element 420 may be arranged to be movable towards and away from the first bend 10, preferably along a first direction LD, and the first support element 420 is preferably of a wedge shape, having a tip end directed towards the bend, such that when moving the wedge shaped support element away from the bend 10, a space is provided between the second and third support elements 430, 440.

[0273] The second and third support elements 430, 440 may thereby be moved away from the walls 6, 7 and the second bend by displacing the elements 430, 440 into the acquired space provided by the movement of the first element 420, such as a long a second direction SD. Thus transferring the interior support part 410 to an unlocked state of decreased collective width of the interior support part 410 compared to the locked state. In the unlocked state, the walls 5, 8 may no longer be prevented from passing the protrusions 422 of the second and third support elements 430, 440 and may thereby lifted/slided from the interior support part 110, 210. A locked state is shown in FIG. 17a and an unlocked state is shown in FIG. 17b, the trim profile 1 is shown by dashed line.

[0274] The release of the engagement with the trim profile by transferring the interior support part 110, 210 to an unlocked state makes it easier to displace the trim profile 1 relative to the interior support part 110, 210.

[0275] In one or more examples, the first part 40a of the trim profile is arranged and held between an interior support part 110 according to FIGS. 3, 3a, 3b or FIGS. 17a-b and an exterior support part 120 according to the present disclosure. Additionally, also the second part 40b of the trim profile may be arranged and held between an interior part 210 of the same or different construction than the interior part 110 i.e. the one shown and described in relation to FIGS. 3, 3a, 3b or FIGS. 17a, 17b and an exterior support part 220 according to the present disclosure.

[0276] FIG. 18 shows an exemplary execution of the method according to one or more aspects of the disclosure and to manufacturing system for executing the method according to the present disclosure. The trim profile 1 illustrated in FIG. 18, may be a trim profile according to any of the previous embodiments and as illustrated in any of the previous figures.

[0277] The manufacturing system comprises a conveyor system 700 having two or more conveyor belts 710 for transferring the trim profiles 1 horizontally along a second direction SD as indicated in the figure. The conveyor system 700 is provided with holding means 720 for holding a trim profile 1 in place, such that the trim profile 1 is not displaced during transfer along the second direction SD. In one or more embodiments, the holding means may comprise an interior support part 110, 210 according to the present disclosure, for holding the trim profile 1. Optionally further fixing means, such as clamps, may be provided at an exterior surface of the trim profile, e.g. such as near wall parts 5, 8, the second bends 20a, 20b and/or the wall parts 6,7 to further fixate the trim profile 1. The trim profile 1 may be transferred in a stepwise manner, such that the trim profile 1 is stationary at each work station 501, 502, 503, while a method step is executed on the trim profile 1.

[0278] The manufacturing system is seen comprising at least three work stations 501, 502, 503, a first work station 501 for providing a pre-cutting operation, wherein a cut-out 3 and/or a further cut-out 15 is provided. A second work station 502 where the trim profile 1 is arranged in the first and second fixation arrangements 100, 200 and where the deep drawing operation is undertaken by the stomping tool 300 and a third work station 503 where a post-cutting operation is taking place and where a third fixation arrangement 800 is located for holding excess material to be separated from the trim profile end wall part 30a.

[0279] The conveyor system 700 may comprise longitudinal displacement means for displacing the trim profile 1 along a longitudinal extent thereof in and out of the work stations 510, 520, 530, e.g. an end of the trim profile 1 may be displaced in and out of the fixing arrangements 100, 200 and the work space 310 provided in the second work station 520 along a third direction, e.g. being perpendicular to the first direction LD and second direction SD. In one or more embodiments, the conveyor system may comprise vertical displacement means for lifting and lowering the trim profile 1 along the first direction LD, preferably such that the trim profile may be lowering into an interior support part 110, 120.

[0280] The pre-cutting operation and the post-cutting operation in FIG. 18 is provided by a laser system 620 mounted on an industrial robot 610 which in turn is mounted on a rail system 600, such that the industrial robot 610 with the laser system 620 can be displaced along the second direction SD between the first and third work station 501, 502 as indicated in the figure.

[0281] The method may be executed as follows; a trim profile 1 to be provided with an end wall part 30a is placed in the holding means of the conveyor system 720 and at a first work station 501, either transferred there by the conveyor system 700 or as a part of step of placing the trim profile on the conveyor belts 710. The industrial robot 610 and the laser system 620 is provided at the first work station 501 and the pre-cutting operation, providing a cut-out 3 and/or a further cut out 15 in the trim profile, is provided by means of the laser system 620.
