DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) FIG. 1 and FIG. 2 show a crimping die device 15 with a first moveable pressing die 20 and a first drive device 22, which are arranged on the base structure 17. The moveable pressing die 20 is arranged on a second guide device 25 in a vertically moveable manner if the crimping die device 15 is arranged on a substrate in the ready-to-use state. The drive device 22 comprises a first drive 23, which is connected to the moveable wedge flange 30. The wedge flange 30 comprises a sliding block guide 35 and can be transferred from a working position into a resting position by means of the first drive device 22, wherein the wedge flange 30 in its working position is operatively connected to the first moveable pressing die 20 and thereby supports the first moveable pressing die 20 (see FIG. 2). The first drive device 22 designed as a pneumatic drive device is designed as a double-acting guide cylinder with an integrated linear guide 28 and comprises an air chamber as the first drive 23, and a piston rod 26 for linear movement or transfer of the wedge flange 30. The base structure 17 is a connecting structure designed as a base plate and comprises a first guide device 18 designed as a groove structure 19, which extends along the base structure 17 and in which the guide section 40 of the moveable wedge flange 30 is arranged.

(13) A projection 38 is arranged on the first moveable pressing die 20 and an oblong hole 39 is arranged on the second guide device 25. The projection 38 extends through the oblong hole 39 and can be moved along the longitudinal extension of the oblong hole 39. Furthermore, a spring-formed pre-tensioning element 27 for pre-tensioning the first moveable pressing die 20 is present, which is arranged at the second guide device 25 and is connected to the projection 38 of the first moveable pressing die 20. The pre-tensioning element 27 presses the first moveable pressing die 20 onto the wedge flange 30 so that the operative connection between the first moveable pressing die 20 and the wedge flange 30 is formed in a vibration-free manner and thus, a continuous contact exists between the contact surface 31 of the wedge flange 30 and the first moveable pressing die 20 (see FIG. 2).

(14) The first moveable pressing die 20 is connected to a gear unit 32, which comprises a connection beam 33. The connection beam 33 is fixed to the first moveable pressing die 20 by means of the fastening means 21, which includes screws and centring sleeves here (not visible). On the connection beam 33, a plain bearing is arranged as a contact geometry 29, which engages into the sliding block guide 35 of the wedge flange 30. The gear unit 32 is designed to transfer a movement and/or a force from the moveable wedge flange 30 to the first moveable pressing die 20. The wedge flange 30 is driven by the first drive device 22 so that the first moveable pressing die 20 can be moved in one direction towards the crimping position and the wedge flange 30 can be essentially moved in a normal manner in the direction of the first moveable pressing die 20 towards the working position. The movement of the first moveable pressing die 20 towards the crimping position is the vertical direction in the ready-to-use state of the crimping die device 15. The movement of the wedge flange 30 towards the working position is the horizontal direction in the ready-to-use state of the crimping die device 15. The wedge flange 30 is positioned in its working position between the first moveable pressing die 30 and the base structure 17, wherein the first moveable pressing die 20 rests on the contact surface 31 of the wedge flange 30, thereby being in its crimping position (see FIG. 2). Thereby, not only the wedge flange 30 is moved by the first drive device 22, but also the first moveable pressing die 30 is transferred from the resting position to the crimping position.

(15) FIG. 3 shows the wedge flange 30, which has a contact surface 31 and a base surface 34. The contact surface 31 is operatively connected to the first moveable pressing die 20 in the working position of the wedge flange 30 in order to support this, for example, in the crimping position. The base surface 34 of the wedge flange 30 is arranged in the groove structure 19 of the base structure 17 so that the wedge flange 30 is kept stable. Between the contact surface 31 and the base surface 34, there is a wedge angle β, which is 5°. The sliding block guide 35 of the wedge flange 30 comprises a first sliding block inclination 36 and a further sliding block inclination 37. Thereby, the first sliding block inclination 36 is much steeper than the further sliding block inclination 37, wherein the further sliding block inclination 37 is parallel or runs parallel to the contact surface 31 The first sliding block inclination 36 thus causes a relatively large lifting movement (in the vertical direction) for the first moveable pressing die 20, wherein a relatively small level of force is exerted onto the first moveable pressing die 20. The further sliding block inclination 37 causes a great amount of force to be exerted onto the first moveable pressing die 20 with a slight lifting movement. The sliding block guide 35 comprises a sliding block guide opening 42 with an opening limitation 43, which forms opening along the further flat sliding block inclination 37 in order to relieve the contact geometry 29 engaging into the sliding block guide 35 from the high level of force exerted during the crimp process. The wedge flange 30 comprises a connecting section 41, which is connected to the first drive 23.

(16) FIG. 4 shows a crimping die device 115, which is essentially designed like the previously described crimping die device 15. The crimping die device 115 differs from the crimping die device 15 in accordance with FIG. 1 to FIG. 3 in that a different wedge flange 130 is present and the first moveable pressing die 120 with a second drive device 150 and a second drive 151 can be transferred from the resting position to the crimping position. This makes the first moveable pressing die 120 moveable independent of the moveable wedge flange 130. For this reason, the wedge flange 130 differs from the wedge flange 30 in accordance with FIG. 1 to FIG. 3 in that the wedge flange 130 does not comprise a sliding block guide and no gear unit is present. The wedge flange 130 comprises the contact surface 131, which supports the first moveable pressing die 120 in its crimping position. The moveable wedge flange 130 connected to the first drive device 22 is positioned in its working position between the base structure 17 and the first moveable pressing die 120. Furthermore, the wedge flange 130 comprises a guide section 140 that is designed as a projection, by means of which the moveable wedge flange 130 is moveably positioned in the groove structure 19. The wedge flange 130 comprises a connecting section 141, which is connected to the drive 23.

(17) On the first moveable pressing die 120, a crimping tool 16 is arranged, which can also be positioned on the first moveable pressing die 20 of the crimping die device 15 in accordance with FIG. 1 and FIG. 2.

(18) FIG. 5 shows a crimping press 200 with the crimping die device 15 in accordance with FIG. 1 and FIG. 2, as well as with a wedge flange 30 in accordance with FIG. 3. The crimping press 200 comprises a further pressing die 220, on which a crimping tool 216 is arranged. The further pressing die 220 is arranged on a crimp drive device 222 with a crimp drive 223, which is designed to transfer the further pressing die 220 from its resting position into its crimping position. Between the first moveable pressing die 20 and the further pressing die 220, the crimping region 215 extends, in which a cable and a connecting element, such as a plug, an eyelet or a socket for example, are positioned when creating a crimp connection.

(19) The base structure of the crimping press 200 is identical to the previously described base structure 17 of the crimping die device 15. The crimping press 200 comprises a housing structure 217, which is connected to the base structure 17. The housing structure 217 comprises a further guide device 238, along which the further pressing die 220 can be transferred from its resting position in its crimping position.

(20) On the basis of FIG. 5 to FIG. 8, a method for creating a crimp connection with a crimping die device 15 in accordance with FIG. 1 and FIG. 2, a wedge flange 30 in accordance with FIG. 3 and a crimping press 200 in accordance with FIG. 5, is described. FIG. 6 shows the crimping die device 15, wherein the wedge flange 30 is in its resting position and the first moveable pressing die 20 is in its resting position. FIG. 7 shows the crimping die device 15, wherein the wedge flange 30 is between its resting position and its working position and the first moveable pressing die 20 is between its resting position and its crimping position. FIG. 8 shows the crimping die device 15, wherein the wedge flange 30 is in its working position and the first moveable pressing die 20 is in its crimping position.

(21) In a first step (step a)), the transfer of the first moveable pressing die 20 from its resting position into its crimping position takes place. The first moveable pressing die 20 is connected to the wedge flange 30 by the connection beam 33 with its plain bearing designed as contact geometry 29 engaging into the sliding block guide 35 and the connection beam 33 being attached to the first moveable pressing die 20 by means of the fastening means 29. The wedge flange 30 is moved with the aid of the first drive 23 and the first drive device 22 in the direction of the first moveable pressing die 20. The wedge flange 30 is pressed from its resting position along the first guide device 18 in the direction of its working position. The contact geometry 29 glides along the first sliding block inclination 36 of the sliding block guide 35, whereby the first moveable pressing die 20 is pressed with the aid of the gear unit 32 when transferring in the direction of the further pressing die 220 (see FIG. 7).

(22) In a further step (step b)) the positioning of the wedge flange 30 between the base structure 17 and the first moveable pressing die 20 is carried out. Thereby, the wedge flange 30 is operatively connected to the first moveable pressing die 20 by the contact surface 31 supporting the first moveable pressing die 20 and raising the first moveable pressing die 20 due to the wedge angle β between the contact surface 31 and the base surface 34 of the wedge flange 30. The wedge flange 30 is transferred into the working position by means of the first drive device 22 and the first moveable pressing die is simultaneously transferred into the crimping position (see FIG. 8). The contact geometry 29, which is designed as a plain bearing, glides along the further sliding block inclination 37 of the sliding block guide 35, which is flatter than the first sliding block inclination, whereby the first moveable pressing die 20 is pressed further in the direction towards the further pressing die 220 with the aid of the gear unit 32 during transfer. Subsequently or at the same time, the first moveable pressing die 20 is transferred by means of the pre-tensioning element 27 in the direction of the resting position (see FIG. 2) so that the first moveable pressing die 20 is ultimately in the crimping position. After a cable and a connecting element designed as a socket, for example, have been positioned in the crimping region 215, then the crimping of a crimp connection takes place using a further pressing die 220, wherein at least one crimping tool 216 is arranged on one of the two pressing dies 20 and 220 (step c)). The further pressing die 220 is guided with the aid of the crimp drive 151 towards the first moveable pressing die 20 so that the crimping tool 216 can create the crimp connection.
