Definitions

  • the invention relates to a device and a method for molding and / or hardening of sheet metal components, according to the preamble of claim 1, or according to the preamble of claim 4, such as from US2004 / 0000184 A1 known.
  • the object of the invention is to provide a device for forming and / or hardening of sheet metal components, which makes it possible in a simple and effective manner to produce undercuts, indentations or indentations, which are also subject to curing in these areas.
  • the slides which are responsible for the molding of undercuts, indentations or enforcements, formed water-cooled, so that even in the region of undercuts indentations or indentations reliably hardening is achieved by the cooling.
  • wedge drives In order to produce indentations, indentations, undercuts and the like, it is known to use so-called wedge drives, wherein a wedge drive 1 comprises a slide lower part 2 and a slide upper part 3. Slide upper part and lower slide part can slide on one another here on an inclined wedge surface, the slider upper part 3 being moved along the direction of arrow 6 by the sliding movement on the inclined surface. This makes it possible to carry out an impression to a metal sheet to be formed.
  • Such wedge drives are arranged in forming tools and are provided via an actuating surface 5 is actuated by a tool upper part in that the tool upper part presses on the actuating surface 5 and thereby carries out the displacement in the direction 6.
  • Such a slide upper part has a component-side mounting surface 7 for receiving a pusher tool 8, wherein the pusher tool 8 itself is responsible for the forming, indenting, undercut or hole punching.
  • the slide upper part feeding holes 9 are guided, which open at the surface 7 and laxative holes 10 are present, which are guided by the surface 7 in the slide upper part.
  • cooling liquid can be guided to the surface 7 and discharged through the holes 10.
  • the pusher tool 8 has in a surface 12, which faces the surface 7 in the assembled state, backward milled channels or grooves 13 which at least partially aligned with the holes 9, 10 or cooperate, that through the holes 9 cooling liquid into the grooves or channels 13 can be guided and can be discharged accordingly through the holes 10 from the grooves 13.
  • a cooling of the slide tool 8 can be brought about.
  • the slider member carrying the slider tool is appropriately equipped with the water cooling.
  • the slide tool 8 may also have a central inlet bore and a central drain hole or more Zulaufbohrungen or more drain holes, which the cooling liquid in the Slider tool 8 arranged cooling holes or cooling channels leads.
  • cooling channels or cooling grooves can be arranged between the slide tool 8 and the surface 7 of the upper slide part 3, a seal.
  • a working slide 8a with a filling slide 8b is in Fig. 2 shown.
  • the filling slide 8b virtually offers the re-storage for the slide 8a and the slide tool 8a. In this way, the undercut 16 can be generated, wherein both slides are moved back against the arrow directions before molding and thus allow a shaping of the component 15 upwards.
  • the pusher tools can all be cooled, not just the tools of the work pusher.
  • coolant-carrying parts are not designed as grooves, but as introduced into the slide tool 8a, 8b channels or holes.
