DETAILED DESCRIPTION

[0060] FIG. 1 shows the construction of an exemplary embodiment of a riveting device 1 which is also referred to as a setting device by experts. The exemplary riveting device 1 is suitable for applying or setting rivets according to the blind riveting method, and in this regard is designed for using blind rivets.

[0061] The exemplary riveting device 1 comprises a riveting tool 10 and a drive device 30 for actuating the riveting tool 10. Preferably, the riveting tool 10 is assigned to a tool housing 4. Preferably, the drive device 30 is assigned to a device housing 5, in particular received therein. Preferably, the tool housing 4 is a metal housing. Preferably, the device housing 5 is a plastic housing.

[0062] The exemplary riveting device 1 can be a hand riveting device. The hand riveting device 1 has a gripping surface 2.1 which can be formed at least partially on the device housing 5. For example, the hand riveting device 1 has a handle part 2 which is at least partially formed by the device housing 5. The riveting device 1 can be held in the hand by the gripping surface 2.1 or the handle part 2 when it is used for setting a rivet, in particular a blind rivet, on a workpiece. The riveting process as such then takes place by actuating the riveting tool 10 via the drive device 30.

[0063] Preferably, the drive device 30 is an electromechanical drive device. The electromechanical drive device 30 comprises, for example, an electric motor 31 having a rotatable output shaft 31.1 and preferably a spindle gear 32, which can be driven by the electric motor 31. Preferably, the spindle gear 32 is set up to convert a rotational drive movement coming from the output shaft 31.1 into a translational drive movement which acts along an operative axis W to actuate the riveting tool 10. The spindle gear 32 can be a ball screw drive.

[0064] In the exemplary riveting device 1, for example at least one, preferably two reduction stages 37, 37 can be interposed between the electric motor 31 and the spindle gear 32. For example, the reduction stages 37, 37 are connected in series in the force flow. For example, the reduction stages 37, 37 use a common intermediate shaft 38. For example, at least one of the reduction stages 37, 37 is a spur gear stage and the associated gear elements are spur gearwheels.

[0065] A preferably replaceable electrical energy storage device, such as an accumulator 3, can be provided for the electrical energy supply of the drive device 30, which energy storage device is arranged, for example, in the region of an end of the handle part 2 facing away from the riveting tool 10. Therefore, the riveting device 1 can be a cordless tool.

[0066] The riveting tool 10 can comprise a mouthpiece 11 and a mandrel holder 12 that can be moved relative to the mouthpiece 11 in the direction of the operative axis W. For example, the mandrel holder 12 has a chuck housing 13 and at least one, preferably several clamping elements 14, 14, in particular clamping jaws, which can be moved in the chuck housing 13 along a clamping path. Preferably, the mouthpiece 11 and/or the mandrel holder 12 and/or the chuck housing 13 and/or the clamping elements 14, 14 are a metal part.

[0067] The mouthpiece 11 serves, for example, to receive a rivet (not shown in FIG. 1) to be set, in particular a blind rivet, and preferably has a through hole 11.1, in order to insert the rivet mandrel of the rivet therein. The mandrel holder 12 serves, for example, to fix the rivet mandrel, so that a non-displaceable connection between the received rivet mandrel and the mandrel holder 12 is created. This can take place, for example, via the chuck housing 13 with the clamping elements 14, 14 arranged moveably therein, by means of which the rivet mandrel is fixed in the chuck housing 13, in particular is clamped therein.

[0068] The riveting tool 10 can be actuated by the drive device 30 so that the mandrel holder 12 or the chuck housing 13 is moved away from the mouthpiece 11 with the rivet mandrel, fixed thereinto, in the direction of the operative axis W. This happens, for example, by the drive device 30 pulling the mandrel holder 12 or the chuck housing 13 away from the mouthpiece 11. This mode of operation, which is known per se, and the blind riveting which can be carried out with it is described in more detail in the publication EP 0 116 954 A2, to which reference is hereby made for the purpose of completing and supplementing the present disclosure, with the note that the publication may attach a meaning to identically worded terms which differs from the present meaning.

[0069] Preferably, the mouthpiece 11 is fixed to the tool housing 4, for example screwed to it. Preferably, the mandrel holder 12, in particular the chuck housing 13, is received in the tool housing 4 so as to be moveable in the direction of the operative axis W. For example, the tool housing 4 has a longitudinal, in particular tube-shaped base body. In this respect, the tool housing 4 is also referred to as a setting sleeve by experts. For example, the mouthpiece 11 is fixed on one end of the tool housing 4 and the opposing end faces towards the device housing 5.

[0070] Preferably, the spindle gear 32 is arranged in the device housing 5. Preferably, the spindle gear 32 comprises a threaded spindle 33 having a feed thread and a spindle nut 34 that is or can be engaged therewith. Preferably, the threaded spindle 33 has a front end 33.1, facing towards the mandrel holder 12, in particular the chuck housing 13, and an opposing back end 33.2. Preferably, the threaded spindle 33 and the spindle nut 34 are arranged concentrically to each other with regard to a transmission axis. Preferably, the spindle axis S of the threaded spindle 33 lies on the transmission axis. Preferably, the output shaft 31.1 of the electric motor 31 is arranged axially parallel to the transmission axis. Preferably, the transmission axis or the spindle axis S lies on the operative axis W.

[0071] For example, the threaded spindle 33 and the spindle nut 34 are set up in such a way that the spindle nut 34 is the gear element that is or can be driven by the electric motor 31 and the threaded spindle 33 is used for performing the translational drive movement in order to actuate the riveting tool 10. For example, the threaded spindle 33 is non-displaceably connected directly or indirectly to the mandrel holder 12 or the chuck housing 13, at its front end 33.1, for example via an intermediate piece. For example, the spindle nut 34 is also rotatably mounted in the radial direction relative to the transmission axis or the operative axis W via at least one, preferably two radial bearing 35, 35 in the device housing 5.

[0072] In the exemplary riveting device 1, a torque arm 41 is provided for example, in order to secure the threaded spindle 33 against rotation relative to the device housing 5. For example, the torque arm 41 is arranged on the threaded spindle 33, in particular fixed thereon or connected thereto in a rotationally fixed manner. For example, the torque arm 41 is supported against a counter bearing 43, preferably via at least one sliding body or rolling body, in order to form the rotation lock for the threaded spindle 33. The counter bearing 43 itself can be arranged rotationally fixed or secured against rotation with respect to the device housing 5. For example, the counter bearing 43 has at least one guide track on which the torque arm 41 is guided while maintaining the rotation protection when the threaded spindle 33 performs a translational movement along the operative axis W.

[0073] In the exemplary riveting device 1, a spring element 15 is provided, for example, which acts with a force in the mandrel holder 12, for example via a pressure part 16. For example, the spring element 15 is arranged in the threaded spindle 33. For example, the threaded spindle 33 and/or the torque arm 41 serves as a counter holder for the spring element 15.

[0074] The force of the spring element 15 can be used as a pretension force which causes or at least helps the rivet mandrel to be fixed in the mandrel holder 12. For example, the spring element 15 is provided in order to apply a spring force to the clamping elements 14, 14 to force them into the chuck housing 13. As a result, the clamping elements 14, 14 are pushed into a clamping position against a rivet mandrel, for example of a blind rivet, which has been introduced via the through hole 11.1 of the mouthpiece 11 into the chuck housing 13. For example, the spring element 15 is a compression spring.

[0075] Preferably, the threaded spindle 33 is formed as a hollow spindle with a through hole 40 extending in the direction of its longitudinal extension. The through hole 40 makes it possible to remove from the riveting tool 10 any rivet mandrel remnants remaining from a riveting process. In this case, for example, the pressure part 16 arranged on the front end 33.1 of the threaded spindle 33 is received in the through hole 40 and itself is formed as a hollow body having a through hole 16.1.

[0076] For example, the through hole 40 on the back end 33.2 of the threaded spindle 33 leads into a tubular element 50, which in turn leads into a collection container 60. For example, in this manner, a mandrel removal path is realised via the threaded spindle 33, wherein the collection container 60 can serve as a collector for mandrel remnants. Preferably, the collection container 60 is arranged fixed integral with the housing relative to the device housing 5, in particular arranged releasably, for example fixed on the device housing 5, in particular releasably fixed thereon.

[0077] For example, the torque arm 41 is also formed as a hollow body having a through hole which is a component of the mandrel removal path to the collection container 60, for example. For example, the torque arm 41 engages into the through hole 40 of the threaded spindle 33 and the tubular element 50 engages into the through hole of the torque arm 41.

[0078] In the exemplary riveting device 1, a support structure 39 is provided, for example, on which on the one hand the tool housing 4 and on the other hand an axial bearing 36, preferably formed as a thrust bearing, are supported axially with respect to the operative axis W, which in turn is supported axially on the spindle nut 34. The mouthpiece 11 is therefore mounted on the axial bearing 36 via the tool housing 4 and the support structure 39, which is in turn supported on the spindle nut 34. In this manner, a load path is formed for the setting force occurring during a riveting process by bypassing or mostly bypassing the device housing 5.

[0079] With the riveting device 1, a supporting structure 7 is provided for example, which supports the tool housing 4. A connection between the tool housing 4 and the supporting structure 7 is therefore realised in that the tool housing 4 is held on the supporting structure 7 via a retaining structure 6, preferably releasably held. In order to illustrate this better, in FIG. 2 the exemplary riveting device 1 is shown in the region of the connection of the tool housing 4 on the supporting structure 7 in an enlarged section of FIG. 1. The supporting structure 7 itself is shown in FIG. 3 in a perspective representation.

[0080] The supporting structure 7 is formed in a ring shape for example. The support structure 39 can have a circumferential collar 39.3 on its outer circumference, which for example engages into a receptacle 5.3 of the device housing 5 with an axial and/or radial clearance. In particular, as can be seen from FIGS. 2 and 3, the supporting structure 7 can be arranged on the support structure 39, in particular formed thereon, for example moulded thereon.

[0081] In particular, it can be provided that the supporting structure 7 and the support structure 39 are formed on a common component. In this respect, the ring-shaped supporting structure 7 or the support structure 39 can have a flange surface 39.2 on its inner circumference, which corresponds to a flange surface 4.2 of a flange 4.1 of the tool housing 4. This is to be able to form the above-described load path. For this purpose, the flange surfaces 39.2, 4.2 can be formed as a circumferential slanted surface. For example, the slanted surface widens radially in the direction of the mouthpiece 11.

[0082] The support structure 39 can be formed as a bearing housing on its end face facing towards the axial bearing 36 and for example can have a recess 39.5, in which the axial bearing 36 is at least partially received or pushed. For example, the axial bearing 36 is an axial roller bearing. In principle, the axial bearing 36 can also be a needle bearing.

[0083] The support structure 39 can be circular. For example, the support structure 39 has a groove 39.4 on the outer circumference, the longitudinal extension of which extends in the direction of the operative axis W and a spring section of the device housing 5 (not shown in the figures) engages into the groove 39.4, in order to secure against rotation. Preferably, the support structure 39 is designed to be resistant to deformation, in particular bending-resistant. For example, the support structure 39 is a metal part.

[0084] As already explained above, the tool housing 4 is held on the support structure 39 via the retaining structure 6. FIG. 4 shows the exemplarily used retaining structure 6 in a perspective representation for illustration purposes.

[0085] Preferably, the retaining structure 6 is a separate component. For example, the retaining structure 6 has a through-hole 6.1 in a wall surface 6.2. For example, the tool housing 4 is received in the through-hole 6.1 or the retaining structure 6 is inserted into the tool housing 4. In this respect, the retaining structure 6 may be a union element, for example. For example, the wall surface 6.2 serves as an axial limitation for the flange 4.1 of the tool housing 4 in the region around the through-opening 6.1

[0086] The radial dimensions of the retaining structure 6 are adapted to the radial dimensions of the device housing 5, for example. For example, the device housing 5 has at least one partially tube-shaped contour 5.2 in the region around the operative axis W. For example, the tube-shaped contour 5.2 is coaxial to the operative axis W. For example, the retaining structure 6 is arranged on an end face 5.4 of the tube-shaped contour 5.2 facing towards the mouthpiece 11. For example, the retaining structure 6 is circumferential around the outer circumference of the tool housing 4 in relation to the operative axis W and the interior space of the tube-shaped contour 5.2 of the device housing 5 is closed at an end face.

[0087] With the exemplary riveting device 1, a fixing of the retaining structure 6 is provided by way of example on the supporting structure 7 via a bayonet lock 70. In addition to the proposed construction of the supporting structure 7 or the support structure 39 and the retaining structure 6, a fixing of the tool housing 4 on the supporting structure 7 is favoured in relation to the operative axis W in an axially compact manner with the bayonet lock 70.

[0088] For example, the bayonet lock 70 comprises a bayonet connection 71 which is assigned to the retaining structure 6, in particular arranged thereon, for example is formed thereon. For example, the bayonet connection 71 is arranged at a radial distance from the through-opening 6.1. For example, the bayonet connection 71 has a ring structure and the inner circumference of the ring structure surrounds the through-opening 6.1 at a radial distance. For example, the ring structure is concentric to the through-opening 6.1 in relation to the central axis thereof M2.

[0089] The bayonet connection 71 comprises. For example, a plug-in receptacle 72 in a ring-shaped recess 6.3 in the retaining structure 6 having a circumferential surface 72.1 and a base surface 72.2. The circumferential surface 72.1 is circumferential at a radial distance around the through-opening 6.1, for example. The bayonet connection 71 also comprises at least two radially inwardly protruding ring segments 73, 73, which are preferably on the circumferential surface 72.1, preferably arranged distributed over the circumference of the plug-in receptacle 72 and serve to lock the bayonet lock 70.

[0090] The bayonet lock 70 has a further bayonet connection 74 which is provided on the supporting structure 7. For example, the further bayonet connection 74 is arranged on a ring-shaped extension 39.1 of the supporting structure 7 or support structure 39, in particular formed thereon. For example, the ring-shaped extension 39.1 is smaller in diameter than the outer contour of the support structure 39, so that a circumferential shoulder 39.6 is formed.

[0091] For example, the ring-shaped extension 39.1 is formed in order to be plugged into the plug-in receptacle 72 of the retaining structure 6 as a plug-in part for insertion. For example, the flange surface 39.2 cooperating with the flange 4.1 of the tool housing 4 is formed on the inner circumference of the extension 39.1. For example, at least two radially outwardly protruding ring segments 75, 75 are provided on the outer circumference of the extension 39.1, which are arranged distributed over the outer circumference and serve to lock the bayonet lock 70.

[0092] Preferably, the at least two ring segments 73, 73 of the bayonet connection 71 form gaps between each other, via which the plug-in receptacle 72 is accessible in an axial direction. Preferably, the at least two ring segments 75, 75 of the ring-shaped extension 39.1 similarly form gaps between each other. Preferably, the gaps are dimensioned such that the at least two ring segments 73, 73 on the plug-in receptacle 72 fit into the gaps between the at least two ring segments 75, 75 of the extension 39.1 when the extension 39.1 is plugged into the plug-in receptacle 72. Preferably, in the same manner, the gaps between the at least two ring segments 73, 73 on the plug-in receptacle 72 are dimensioned so that the at least two ring segments 75, 75 of the extension 39.1 fit into the gaps between the at least two ring segments 73, 73 of the plug-in receptacle 72 when the extension 39.1 is plugged into the plug-in receptacle 72.

[0093] The bayonet connection 71 and the other bayonet connection 74 enables a mechanical connection or fixing of the retaining structure 6 having the supporting structure 7 by a plug-in rotary movement. In a first step, the plug-in receptacle 72 of the retaining structure 6 is pushed onto the tube-shaped extension 39.1, i.e. the tube-shaped extension 39.1 is plugged into the plug-in receptacle 72. The achieved plugged connection between the retaining structure 6 and the supporting structure 7 while receiving the tool housing 4 is shown simplified in a sectional representation in FIG. 5. In this state, the retaining structure 6 and the supporting structure 7 are releasable from each other in an axial direction. Preferably, the central axis M2 of the through-opening 6.1 of the retaining structure 6 and the central axis M1 of the supporting structure 7 are placed coaxially to each other.

[0094] In a second step, the retaining structure 6 is rotated relative to the supporting structure 7 around the central axis M1 or M2, thereby causing the ring segments 73, 73 on the retaining structure 6 to engage with the ring segments 75, 75 on the supporting structure 7 and forming a locking of the bayonet lock 70, by which releasing of the retaining structure 6 from the supporting structure 7 is blocked in a form-fitting manner in the axial direction. This state is represented simplified in a sectional representation in FIG. 6.

[0095] Preferably, an abutment or a rotary abutment is provided (not shown in the figures), by which the rotational movement of the retaining structure 6 is limited relative to the supporting structure 7 when locking the bayonet lock 70. Therefore, in the locking position of the bayonet lock 70, the retaining structure 6 is brought into a desired rotational position. Over-rotation is prevented by the abutment, so that any release of the locking caused thereby is prevented.

[0096] However, a further effect can be used by the abutment. For example, a light source 80, such as for example an LED, is arranged in the device housing 5. A ring having multiple light sources 80, 80, in particular LEDs, arranged distributed over the circumference can also be provided, which extends around the operative axis W. For example, in this case, the retaining structure 6 has one or more light guides 81, 81 in order to thereby transmit light rays of the light source 80 or 80 in the direction of the mouthpiece 11. For example, the light guide 81 or 81 is connected downstream of the bayonet lock 70 or the support structure 39 when viewed radially outwards.

[0097] It is ensured with the abutment that, in the locking position of the bayonet lock 70, the light guide 81 or 81 is located in the predetermined position, that a desired radiation of the light rays created by the associated light source 80 or 80 takes place, in particular takes place in the desired direction.

[0098] FIG. 7 shows by way of example a further embodiment of a riveting device 1. FIG. 7 shows the other exemplary riveting device 1 by way of example in a section, which is represented in a comparable manner to the riveting device 1 in FIG. 2. Components of the further exemplary riveting device 1 which are structurally or functionally identical to components of the exemplary riveting device 1 of FIGS. 1 to 2 are provided with the same reference numerals; in this respect, reference is made to the description of the exemplary riveting device 1 of FIGS. 1 to 2.

[0099] The other exemplary riveting device 1 differs from the exemplary riveting device 1 of FIGS. 1 and 2 in that a device housing 5 receiving the drive device 30 is provided which is used for the bayonet lock 70. In the further exemplary riveting device 1, the above-described bayonet connection 74 is assigned to the device housing 5, for example the tube-shaped contour 5.2 of the device housing 5, in particular arranged thereon, for example moulded thereon.

[0100] In the further exemplary riveting device 1, a support structure 39, for example, is provided which can correspond to the support structure 39 of the exemplary riveting device 1, for example without the ring segments 75, 75 of the bayonet connection 74, however.

[0101] In contrast, in the further exemplary riveting device 1, the device housing 5 has a ring-shaped extension 5.1, on the outer circumference of which the at least two radially outwardly protruding ring segments 75, 75 of the bayonet connection 74 are arranged or formed. The device housing 5 can otherwise be structurally identical to the device housing 5 of the exemplary riveting device 1 of FIGS. 1 and 2.

[0102] FIG. 8 shows an example of the device housing 5 in the region of the ring-shaped extension 5.1. For example, the ring-shaped extension 5.1 is formed on the device housing 5, in particular moulded thereon. For example, the ring-shaped extension 5.1 is located on the one end face 5.4 of the tube-shaped contour 5.2 of the device housing 5. For example, the inner circumference of the tube-shaped extension 5.1 surrounds the support structure 39 with radial clearance (FIG. 7).

[0103] FIG. 9 shows by way of example another embodiment of a riveting device 1. FIG. 9 shows the further exemplary riveting device 1 by way of example in a simplified representation as a partial section. Components of the further exemplary riveting device 1 which are structurally or functionally identical to components of the exemplary riveting device 1 of FIGS. 1 and 2 are provided with the same reference numerals; in this respect, reference is made to the description of the exemplary riveting device 1 of FIGS. 1 and 2.

[0104] The other exemplary riveting device 1 differs from the exemplary riveting device 1 of FIG. 1 inter alia in that the drive device 30 comprises a cylinder piston unit 90, which serves to actuate the riveting tool 10. Preferably, the cylinder piston unit 90 has a cylinder 91 and a reciprocating piston 92. For example, the cylinder 91 forms a device housing 5 receiving the drive device 30 or is a component thereof.

[0105] Preferably, the cylinder 91 has a piston space 93 in which the reciprocating piston 92 is received translationally moveably. Preferably, the reciprocating piston 92 is operatively connected to the mandrel holder 12. For this purpose, a piston extension 94 can be arranged on the reciprocating piston 92, in particular moulded thereon, which is connected, in particular screwed to the mandrel holder 12, in particular the chuck housing 13, on an end or end region facing towards the riveting tool 10. For example, the piston extension 94 is tube-shaped. For example, the piston axis K of the reciprocating piston 92 is on the operative axis W. For example, the reciprocating piston 92 is set up to be moved along the operative axis W.

[0106] The drive device 30 can be pneumatically and/or hydraulically driven by the cylinder piston unit 90. For example, at least one supply channel 96 is provided. For example, the supply channel 96 leads into a fluid chamber 95, via which a medium pressure can be exerted onto the reciprocating piston 92. The further exemplary riveting device 1 may be a pneumatically-driven riveting device, for example. Such a pneumatically-driven riveting device is known and is described in more detail in the publication EP 1 132 160 A1, to which reference is hereby made for the purpose of completing and supplementing the present disclosure, with the note that the publication may attach a meaning to identically worded terms which differs from the present meaning.

[0107] With the further exemplary riveting device 1, the mandrel holder 12 is received axially moveably in a tool housing 4 which on the one hand is axially supported on the mouthpiece 11 and on the other hand is axially supported on the cylinder 91 via a flange 4.1. For example, the flange 4.1 has a flange surface 4.2 which corresponds to a mating flange surface 97.1 which is assigned to the cylinder 91. For example, the mating flange surface 97.1 is formed on the cylinder 91. For example, the flange surface 4.2 of the tool housing 4 is arranged transverse, in particular orthogonal, to the operative axis W. For example, the flange surface 4.2 of the tool housing 4 is circumferential around the operative axis W.

[0108] With the further exemplary riveting device 1, a supporting structure 7 is provided, for example, which supports the tool housing 4. A connection between the tool housing 4 and the supporting structure 7 is realised in the present case by the tool housing 4 being plugged into a recess or a through hole of the device housing 5 and/or the cylinder 91 via a longitudinal section 4.3. In this respect, the longitudinal section 4.3 serves as a plug-in section. Preferably, the outer circumference of the plug-in section and the inner circumference of the recess or the through hole correspond accordingly, in particular with a clearance. Therefore, support transverse to the operative direction W is achieved.

[0109] For example, the longitudinal section 4.3 extends from a free end of the tool housing 10, which is opposite to the mouthpiece 11, up to the flange 4.1. The flange 4.1 is provided as a circumferential collar on the outer circumference of the tool housing 4 for example, in particular is arranged or moulded thereon. Thus, the plug-in depth into the device housing 5 or the cylinder 91 is delimited by the flange 4.1.

[0110] With the further exemplary riveting device 1, a retaining structure 6 is provided, for example, in order to prevent the tool housing 4 from falling out of the recess or the through hole of the device housing 5 of the cylinder 91. Preferably, the retaining structure 6 is a separate component. For example, the retaining structure 6 is formed according to the retaining structure 6 of the exemplary riveting device 1 according to FIG. 1. In this respect, reference is made to the above description of the retaining structure 6.

[0111] With the further exemplary riveting device 1, a fixing of the retaining structure 6 is also provided by way of example on the supporting structure 7 via a bayonet lock. The bayonet lock can be the bayonet lock 70 having the bayonet connections 71 and 74, such as is used with the riveting device 1 of FIG. 1. As a result, reference has been made to the above description, in particular of FIGS. 3 to 6.

[0112] With the further exemplary riveting device 1, the bayonet connection 71 is assigned to the retaining structure 6 for example, in particular arranged thereon, for example formed thereon. The further bayonet connection 74 is provided on the supporting structure 7, in particular the device housing 5 or the cylinder 91. For example, the further bayonet connection 74 is arranged on a ring-shaped extension 99 of the supporting structure 7, in particular formed thereon.

The riveting device 1.1 may be a modification of the riveting device 1 of FIG. 1. The spindle gear 32 of the riveting device 1 of FIG. 1 is replaced in the case of the riveting device 1.1 by the cylinder piston unit 90. The cylinder piston unit 90 comprises a cylinder 91 and a reciprocating piston 92 received translationally moveably therein. The reciprocating piston 92 is operatively connected to the mandrel holder 12. The cylinder 91 is supported with an axial end against the support structure 39, which in this case serves as an axial support for the cylinder 91. With the riveting device 1.1, as with the riveting device 1, the support structure 39 and the supporting structure 7 are formed on the same component.

[0114] FIG. 11 shows a further embodiment of a riveting device 1.2 having an embodiment of the cylinder piston unit 90. The riveting device 1.2 is a modification of the riveting device 1.1, in which the supporting structure 7 is provided directly on a cylinder 91.1 of the cylinder piston unit 90, in particular formed or moulded thereon, and for example a separate support structure is omitted. For example, a mating flange 97 for the flange 4.1 of the tool housing 4 is formed on the cylinder 91.1. For example, the mating flange 97 has a mating flange surface 97.1 which corresponds to the flange surface 4.2 of the flange 4.1 of the tool housing 4. For example, in this case, a collar 98 of the cylinder 91.1 takes over the function of the circumferential collar 39.3 of the support structure 39, which is described above for the riveting device 1.1 of FIG. 10 or for the riveting device 1 of FIG. 1.

[0115] FIG. 12 shows a further embodiment of a riveting device 1.3 having an embodiment of the cylinder piston unit 90. The riveting device 1.3 may be a modification of the riveting device 1 of FIG. 7.

The reciprocating piston 92 is operatively connected to the mandrel holder 12. The cylinder 91 is supported with an axial end against the support structure 39, which in this case serves as an axial support for the cylinder 91. With the riveting device 1.3, as with the riveting device 1, the support structure 39 does not form any bayonet connection. The bayonet connection 74 is arranged on the device housing 5, in particular formed thereon.

[0116] FIG. 13 shows a further embodiment of a riveting device 1.4 having an embodiment of the cylinder piston unit 90. The riveting device 1.4 is a modification of the riveting device 1.3, in which the supporting structure 7 is provided directly on a cylinder 91.1 of the cylinder piston unit 90, in particular formed or moulded thereon, and for example a separate support structure is omitted.

FIG. 10 shows the blind rivet nut 210 in the state before riveting, in which the rivet body 230 of the blind rivet nut 210 is still in its initial state.

[0119] For example, with the exemplary blind rivet nut setting tool 200, the pressure part 16 is introduced into a receptacle of the threaded rivet mandrel 220 and forms a form-fitting rotationally-fixed connection to the threaded rivet mandrel 220 via the receptacle. For example, the pressure part 16 is held in the receptacle of the threaded rivet mandrel 220 by the force of the spring element 15 of the riveting device 1 (FIG. 1), which acts axially on the pressure part 16.

[0120] FIG. 16 shows an example of a possible embodiment of a blind rivet screw setting tool 300.
