Definitions

  • the present invention relates to a multi-stage Forming machine with tool combination blocks, as in the preamble of independent claim 1 is defined.
  • DE-A-197 22 228 describes a multi-stage forming machine known in which each tool in a tool cartridge is arranged by means of a clamping device in the Forming machine is held.
  • the clamped tool cartridges can be replaced relatively quickly if necessary be so that the downtime of the forming machine significantly can be reduced.
  • a tool change takes time but still comparatively long because of the fine adjustment the mutual distance between two opposite interacting tools on the forming machine.
  • EP-B-0 354 428 describes a generic multi-stage forming machine described one on a stationary machine body attached first tool combination block with, for example five matrix blocks and one on one in the direction of this first tool combination block reciprocable press slide attached second tool combination block with, for example comprises five stamp blocks.
  • the tool combination blocks are interchangeable as a whole and outside the forming machine adjustable. To ensure sufficient tension the tool combination blocks with the machine body or press slide screwed. This has the Disadvantage that a quick change of tool combination blocks is not possible because of the operating personnel must be handled from the outside with auxiliary tools.
  • a multi-stage forming machine has to be created of the type mentioned at the beginning, in which the downtime the forming machine when changing the tool comparable forming machines of the prior art can be significantly reduced.
  • a multi-stage Forming machine a first and second tool combination block comprises, at least one of which is at least one Has flaps with which he can directly or indirectly on a stationary machine body or on a Pressing slides attached clamping cams directly from above or indirectly on the machine body or on the press slide is attached.
  • the flap and the tensioning cam are like this trained that by the dead weight of the tool combination block and / or one in the vertical direction on the tool combination block acting tension an elastic tension the tool combination block and the machine body or
  • the first and second tool combination block have interacting tool blocks and are stationary Machine body or attached to the press slide, that in the direction of the first tool combination block is movable.
  • the replacement of an entire tool combination block allows fine adjustment the mutual distance between two opposite interacting tool blocks outside the Forming machine, while this is still with the old tool combination block can continue to be operated.
  • the downtime can remove the old tool combination block and the actual attachment of the new tool combination block be restricted.
  • both tool combination blocks are with at least provided with a flap and directly or indirectly on the machine body or press carriage, it is in principle but also conceivable that the one tool combination block is attached in a different way.
  • the mentioned at least one flap in the upper edge area of the tool combination block and in the lower edge area the tool combination block is at least one more Clamping flap arranged over another clamping cam from above directly or indirectly on the machine body or is attached to the press slide.
  • the mentioned at least one flap in the upper edge area of the tool combination block and in the lower edge area of the tool combination block is at least one down protruding clamping cams arranged, which in a direct or indirectly attached to the machine body or to the press slide, inserted upward open flap is.
  • the one or more flaps have and / or the one or more clamping cams to the vertical inclined contact surface for the assigned clamping cam or Flap on, which is preferably curved, so that when exerting a vertically downward force on the tool combination block or the flaps the assigned clamping cam (s) bent outwards will or will.
  • Due to the elastic bend of the or Tension flap (s) can have a high preload in horizontal Direction are generated for a safe, tense Attachment of the tool combination block ensures the emergence counteracts fretting rust and a mutual absolutely precise adaptation of the contact surfaces makes unnecessary.
  • the curvature of the contact surface prevents Edge pressure is created.
  • At least one of the upper edge area two tool combination blocks several clamping tabs and / or in lower edge area of this tool combination block several after clamping cams projecting below are spaced apart. This allows the tool combination block to be wide area can be supported and braced.
  • the tool combination block preferably has clamping tabs or at least one of the tool combination blocks with clamping tabs at least one stop on a stop surface outside the tool combination block on top.
  • the tool combination block becomes vertically precise when it is hooked in positions and defines the maximum tension force.
  • a multi-stage forming machine comprises a machine body 1, on which by means of screws 15 Lock plate 5 is attached.
  • Lock plate 5 In wedge recesses 53 (Fig. 5) Force wedges 16 arranged in the lock plate 5 (Fig. 4) serve in addition to the screws 15 for support the vertical bracing forces that occur.
  • the Machine body 1 and the lock plate 5 run through an ejector rod bore 28 and an ejector rod guide 29 (Fig. 4).
  • the Lock plate 5 two elongated clamping cams 52 on the one on both sides arranged above the lock plate 5 Centering housing 12 each up to its lateral Extend edge.
  • At the lower end of the lock plate 5 are distributed across its width are four flaps that protrude upwards 51 attached.
  • a tool combination block is suspended in the lock plate 5 3 with a support plate 32, a centering plate 36, usually five die blocks 35 and one themselves Block guide extending over the entire width 34.
  • Fig. 6 is a matrix block 35 drawn, by means of Screws 24 is attached to the centering plate 36.
  • the die is clamped using claws 351 and Claw screws 352.
  • the block guide 34, centering plate 36 and support plate 32 are by means of screws 18 and Centering plate 36 and support plate 32 additionally by means of Screws 17 connected together.
  • At the top of the support plate 32 are four evenly distributed across the width Tension flap 31 formed while at the lower end four clamping cams 322 are formed.
  • each two outer clamping tabs 31 are stops 33 by means of Screws 19 attached to the support plate 32 on the stop surfaces 521 on the clamping cams 52 of the lock plate 5 rest and so the tool combination block 3 vertically exactly position.
  • wedge recesses 323 in the support plate 32 arranged force absorption wedges 316 (FIG. 2 and 3) serve in addition to the screws 19 for support of the tension forces that occur.
  • the support plate 32 has in the further slot-shaped recesses 324, which the Allow insertion and removal of the tool combination block 3 while ejector rods in the area of the support plate 32 protrude.
  • a centering pin 11 with a ball head screwed (Fig. 4).
  • the ball head into the centering housing 12 introduced and through its special training (Fig. 5) directed to the desired horizontal position.
  • Hooking the tool combination block 3 into the lock plate 5 is generally done using an external, here unsigned crane device.
  • insertion aids 21, 22 on the machine body 1 and on the Lock plate 5 provided.
  • the clamping tabs 31 of the tool combination block 3 are the tensioning cams 52 of the Lock plate 5 hanged while the clamping cams 322 des Tool combination blocks 3 between the clamping tabs 51 and vertical contact surface of the lock plate 5 and the ball head of the centering pin 11 inserted into the centering housing 12 become.
  • the jigs 7 each comprise a clamping lever 71 which is one at the Lock plate 5 mounted lever axis 73 is rotatable.
