  • the locking device has at least one wedge drive with slider and driver, that function of the force deflection known by wedge drives can be used to simply actuate the locking device if the slide having the spacer element depends on the relative movement between blank holder and tool top when closing the forming tool, is slidably mounted under contact with the driver to move the spacer into its working position.
  • a wedge drive compared to an axle-mounted rocker arm of the prior art be made relatively robust, so that even high loads can be safely removed. In this way, it may for example also be possible to use gas springs as pressure medium.
  • the wedge drive can firmly fix the distance between the blank holder and blank holder on the locking device according to the invention. According to the invention, it is therefore a forming tool provided that can be used even at high loads and always allows a high forming quality.
  • the forming tool can be a deep-drawing tool for tensile-compression-forming according to DIN 8584. Further, it is generally mentioned that a metal sheet, a sheet metal blank (sheet metal blank) or a tailored blank sheet (Tailored Blank) can be formed with this forming tool.
  • the spacer element forms a stop for the blank holder and / or blank holder in its working position.
  • this comparatively mechanically robust solution can further improve the stability of the forming tool.
  • the holding-down device has a shoulder protruding radially from the die, which forms a counterstop for the abutment of the spacer element, the construction of the forming tool can be further simplified.
  • the locking device can be provided outside of cooperating for forming tool parts - with which a relief in the structure reachable and possible interference contours on the forming tool can be avoided.
  • the loads on the movable tool parts or on the upper tool part can be reduced if the driver is attached to the upper tool and the slider is slidably mounted on the blank holder.
  • the slider can be returned to its free rest position after opening the forming tool - structurally simple solved.
  • the spacer element on the slide is displaceably mounted against the action of a second spring whose direction of action opposes the direction of action of the first spring, the spacer element can be moved under pretension into its working position - which can increase the reliable operation of the locking device.
  • the spacer element can be shifted in time offset from the movement of the slide in its working position, which can facilitate the vote of the wedge guide on the relative movement between blank holder and upper tool.
  • the construction of the forming tool can be further simplified in this way.
  • the handling of the forming tool - both when loading with a sheet and when removing the formed sheet / the formed board - is advantageously unimpaired by the locking device, when the slider is slidably mounted so that it in the working position of the spacer element to the die next situated position.
  • Slide velvet spacer are namely with open forming tool from the insertion or removal area between the two tool parts further away, whereby the locking device can not form any interference contours on the forming tool.
  • the locking device can be protected in a structurally simple way from damage caused by the loading / unloading of the sheet - which can contribute to further increase the stability of the forming tool.
  • first and second pressure medium are designed as gas springs.
  • FIGS. 1 to 4 For example, shown as a single-acting press forming tool 1 is used for deep drawing a sheet, a sheet metal blank (sheet metal blank) and / or a custom sheet metal blank (Tailored Blank).
  • Fig. 1 is this forming tool 1 in its open position, in which open position the reshaping flat board 2 is already inserted. In this open position of the forming tool 1, the two tool parts 3, 4 of the forming tool 1 can be seen.
  • the first, upper tool part 3 includes a tool upper part 5, a die 6 and a hold-down 7.
  • the hold-7 is supported against the upper tool 5 via a first pressure medium 8, which is executed in the embodiment as the first gas spring 108 - see the latter Fig. 3 ,
  • the die 6 is rigidly connected to the upper tool 5.
  • the second lower tool part 4 includes a lower tool part 9, a punch 10 and a sheet holder 11.
  • the sheet holder 11 is supported against the lower tool part 9 via a second pressure means 12, which is designed as a second gas spring 112 - see the latter Fig. 3 ,
  • the forming tool 1 according to the invention therefore requires no under-air.
  • the punch 10 of the lower tool part 4 is attached to the lower tool part 9 and cooperates with the die 6 of the upper tool part 3 for forming the board 2 together.
  • the forming tool 1 also has a locking device 13 which is provided between plate holder 11 and hold-down 7.
  • the locking device 13 comprises a spacer element 14, with which the distance between the sheet holder 11 and hold-down 7 can be set. This is necessary for the opening of the forming tool 1, in spite of possibly different pressure forces of the first and second pressure means 8, 12 a high quality, eg. B. at the deformed board 2, to ensure.
  • This locking device 13 is actuated by the closing movement of the forming tool 1, as shown in FIG Fig. 2 can be seen. In synopsis of FIGS.
  • the spacer element 14 is movably mounted in response to a relative movement resulting upon closing of the forming tool 1 - namely from a free rest position 15 when the forming tool 1 is open Fig. 1 in a working position 16 after Fig. 3 , which defines the distance between blank holder 11 and hold-down 7 when opening the forming tool 1.
  • this movement of the spacer element 14 is converted by a wedge drive 17, which belongs to the locking device 13.
  • the wedge drive 17 has a slide 18 and a driver 19, which form corresponding guide surfaces 20 on the wedge drive 17.
  • the slide 18 has the spacer element 14 and is displaceably mounted - namely in the embodiment of the sheet holder 11.
  • the driver 19 which in the embodiment on the upper tool 5 is fixed - moved and thus moves the spacer element 14 under the hold-down 7, whereby the hold-7 abuts the spacer element 14 and thus to the blank holder 11.
  • the spacer element 14 forms a stop 24 for the hold-7.
  • the forming tool 1 according to the invention thus has a particularly high stability.
  • Fig. 1 can be seen further, the slider 18 is slidably mounted against an action of a first spring 21, which is designed as a third gas spring.
  • This spring 21 acts between slide 18 and plate holder 11 and presses the slider 18 along its first linear guide 22 on the blank holder 11 of the die 6 away.
  • the slider 18 comes in the working position 16 of the spacer element 14 of the die 6 closest, which position 23 of the slider in the Fig. 3 can be seen.
  • slide 18 In the rest position 15 of the spacer element 14, slide 18 is arranged furthest away from the die 6. In order for this resulting interference contours are prevented when loading the forming tool 1.
  • the hold-down device 7 forms a shoulder 25 radially projecting the die 6, which forms a counter-abutment 26 for the stop 24 of the spacer element 14.
  • This counter-abutment 26 is provided on the axially projecting portion 27 of the radially projecting shoulder 25, whereby the spacer element 14 can be made demenwitzend reduced in height.
  • the spacer 14 is slidably mounted on the slider 18 against the action of a second spring 28.
  • This designed as a fourth gas spring spring 21 acts between the spacer element 14 and slide 18 and loads the spacer element 14 along its second linear guide 31 on the slider 18 with a direction of action 29, which is opposite to the direction of action 30 of the first spring 21.
  • the spacer 14 can be brought under bias in its working position 16, which bias in Fig. 2 can be seen against the action of the second spring 28 on the basis of the displacement of the spacer element 14.
  • the slide 18 also movably mounted on the upper tool part 5 and the driver can be attached to the blank holder 11.
  • the spacer element forms a stop 24 for the blank holder 11 to determine the distance between blank holder 11 and hold-7. It is also conceivable that the spacer element 14 each forms a stop 24 for blank holder 11 and hold-down 7 - this is also not shown.
