Definitions

  • the invention relates to a method for producing a passage through a stack of at least two plate-shaped workpieces, in which, by means of a passage punch which is guided essentially vertically through the stack, material of one plate-shaped workpiece facing the passage punch through an opening of the other plate-shaped Workpiece is pulled through, the inner contour of the opening substantially corresponds to the outer contour of the passage.
  • Such methods for producing a swipe are known from the prior art.
  • a breakthrough is disclosed in DE 89 03 243, which connects several molded parts lying on top of one another without rivets.
  • the molded parts are individually provided with round holes in a previous step.
  • the hole in an external molded part is smaller than the holes in the other molded parts.
  • the edge zone of the smaller hole of the outer molded part which covers the larger holes of the other molded parts, is pushed through the holes of the other molded parts. This passage protrudes over the outer surface of the other outer molded part and is then flanged.
  • a method of the type mentioned is also known as part of a method for joining panels from DE 40 35 210 A1. There, the panels to be connected are also pre-punched individually in a previous step. The plate forming the passage is not perforated. A pass is created by pushing a cutting punch through the workpieces layered against a pressure plate, the material of the non-perforated plate being pulled through the pre-drilled holes of the other plates and spreading beyond the other plates.
  • a block stamp is additionally used, which flanges the spreads and thus creates a stronger connection.
  • a disadvantage of the known methods is that the molded parts or plates to be connected have to be predrilled individually in a separate operation. When drilling the holes, a distinction must already be made as to whether the respective molded part or the respective plate forms the passage, in which case a small or no hole is made, or whether the passage is pushed through the relevant molded part or the relevant plate, for which then larger holes must be made. Such a method is uneconomical due to the additional work steps and, due to the different bores in the molded parts or plates depending on the intended use, is cumbersome and prone to errors.
  • the object of the present invention is therefore to reduce the number of work steps in the method for producing a riveted connection, to simplify the individual work steps and thus to make the process more economical.
  • the object is achieved for a method of the type mentioned at the outset in that in a single infeed movement of the pull-through die, both the pull-through and the opening are formed on the other plate-shaped workpiece which is at the rear in the feed-in direction of the pull-through die, by the plate-shaped workpiece facing away from the pull-through die is supported by a die in such a way that when the punch is inserted into the stack, a piece of material is broken out of the rear plate-shaped workpiece, the outer contour of which essentially corresponds to the outer contour of the passage.
  • the process for producing the swipe is considerably simplified and less expensive in that the inventor u ⁇ vorunexpectedly succeeded in producing the swipe at the same time as the piece of material breaking out during a single infeed movement of the swaging die through the stack supported by the die.
  • the pull-through can protrude beyond the surface of the rear plate-shaped workpiece facing the die. This is particularly useful if the greatest possible length of the passage is desired, for example when cutting a thread in the passage.
  • the passage can also be processed in further, subsequent procedural steps.
  • the passage that protrudes beyond the surface of the rear plate-shaped workpiece facing the die preferably by means of a flanging punch, which is delivered from a side of the work piece opposite the punching punch, is flanged to produce a rivet-through riveting, after the flanging riveting Outer surface of the passage lies at least in sections on the outer surface of the rear workpiece.
  • a through-opening can be created through the stack before the opening is formed, the cross-sectional area of which corresponds at most to the cross-sectional area of the opening of the through-hole.
  • a passage opening results in a particularly clean passage since the passage punch is centered and guided through the passage opening.
  • the passage in this embodiment contains fewer dimensions. 4 material, so that due to the lower plastic deformation, the passage does not tear at the points of greatest plastic deformation.
  • the through opening is created by the stack with an essentially constant cross section. This enables a particularly quick and inexpensive manufacture of the through opening.
  • the passage opening is created by means of the passage stamp during the feed movement of the passage stamp, during which the passage and the piece of material are formed.

Abstract

Dans les procédés de rivetage connus, pour assembler une pile de pièces, le matériau d'une pièce située à l'extérieur est soyé à travers les trous prépercés individuellement des autres pièces, puis la partie du passage qui fait saillie hors de la dernière pièce est rabattue. L'inconvénient de ce type de procédé est que le perçage préalable des pièces est complexe et onéreux. L'invention vise à mettre au point un nouveau procédé permettant de réduire le nombre d'étapes, de simplifier les étapes individuelles et de rendre ainsi le procédé plus économique et efficace. En outre, l'assemblage doit également pouvoir s'effectuer par surfaces affleurées. Selon l'invention, un seul mouvement d'avancement d'un poinçon de soyage suffit à former le passage soyé dans une pièce et à réaliser les ouvertures dans les autres pièces, par enlèvement d'un ou de plusieurs morceaux de matériau. L'invention concerne en outre la réalisation d'un passage soyé.
