Definitions

  • the invention is based on a method and / or
  • connection point due to the axially symmetric radial expansion tensions, which are not reduced, which also depends on the radial yielding of the walls of the deep-drawing opening and which is at the expense of the strength of the connection point.
  • the inventive method according to the main claim, or the inventive device for performing the method according to the auxiliary claim 8 has the Advantage that plates of different materials can be joined together with high strength. This means that plates made of metal and plastic can also be connected to one another, with sufficient durability. It is particularly advantageous that due to the different deformation of the plate sections in two transverse directions in the first transverse direction and their transitions to the second transverse direction, a relatively strong material displacement takes place with a correspondingly strong grip under the plates by the plate sections, however, at the expense of the thickness and thus also the strength of the wall parts , whereas less material is displaced in the second transverse direction due to the wedge shape of the die and thus the connecting neck between the bottoms of the plate sections and the plates is relatively thick and thus very solid. Since the transition between these two extremes is smooth, the strong neck of the wall parts in the second transverse direction and the strong grip under the plate sections in the first direction have a combined effect on the overall improvement of the connection off, for example also in comparison to all others
  • the stamp and the deep-drawing opening have a circular or oval cross-section
  • the working surface of the molding stamp s is wedge-shaped with a largely rectangular end face, so that strong dilutions bi s tear separations are formed on the sides of the mold tem that face away from one another the wall parts of the second and additional plate sections take place, so that the radial displacement is retained by the wedge surfaces.
  • the volume of the deep-drawing opening in and across the pressing direction is unchangeable, so that during de s The longitudinal and transverse expansion of the deep-drawn surface parts is relentlessly limited and an edge surface extending in the deep-drawing direction is created (EP 0 215 449).
  • the volume of the deep-drawing opening can be increased in the longitudinal and / or transverse direction during the squeezing process (DE-GM 297 00 868, WO 97/02912).
  • the radial outward flow is impeded in the first transverse direction.
  • the front edges that hinder the radial outward flow can also run in another direction, provided that this is advantageous for the inventive process.
  • the first and third plates can be made of metal and the second plate between them can be made of plastic.
  • Such combinations of materials have so far been possible in
  • the shaping stamp has an upper part the wedge shape and the deep-drawing opening have a circular or oval cross-section.
  • the deep-drawing opening in the die is designed in the radial and axial direction as a pocket opening, the side walls of which extend in the direction of movement of the die and, like the bottom surface of the deep-drawing opening, are rigid.
  • the side walls of the deep-drawing opening are designed to be radially flexible, which can be done via elastic means.
  • the intrinsically rigid bottom of the deep-drawing opening can be displaced by a certain stroke when a certain pressing force of the molding die is exceeded.
  • a depression is provided in the bottom of the deep-drawing opening, the depression toward the bottom surface having end edges engaging in the surface part after the deep-drawing process, in order thereby to hinder the radial material flow during the squeezing process, which in turn creates free spaces in which Material of the second or overlying plate sections can flow.
  • the central tri grooves are configured as continuous and / or offset with respect to one another.
  • Figure 1 shows a tool unit, including plates, before processing Figure 2 is a view acc. Arrow II in Figure 1
  • Figure 3 shows a section. Arrow III in Figure 1
  • Figure 4 shows a section through a finished
  • a die 1 is shown in side view, which has a working pin 2 and a holding shaft 3, each with a circular cross section, as can also be seen in Figure 2.
  • the pin 2 has an end face 4 and flats 5, which creates a kind of wedge shape.
  • the end face 4, as can be seen in FIG. 2, forms deep-drawing edges 7 with the lateral surface 6 of the pin 2, of which only the front one can be seen in FIG.
  • this form stamp is arranged in a press via a tool holder in order to be able to carry out a power stroke in the direction of arrow I.
  • a die 8 is arranged in the press, with a deep-drawing opening 9, with fixed radial walls 10 and a base 11 which is also immovable.
  • An annular groove 12 is provided between the base 11 and the wall 10.
  • Three plates are placed on the die 8, namely two metal plates 15 and 17 and a plastic plate 16 arranged between them.
  • the forming die 1 is rubbed downwards in the direction of arrow I, in a first part of his operation he pulls the three plates 15, 16 and 17 deep into the deep-drawing opening 9 until the first lower plate 5 hits the bottom 11, after which, due to the resulting resistance and the continued pressing pressure, the three plates are squeezed become.
  • the first plate 15 is pressed into the longitudinal groove 13, so that the flow process is hindered radially outwards.
  • the squeezed material therefore flows primarily in the direction of the longitudinal groove instead of across it.
  • the plate sections of the plates 16 and 17 drawn into the deep-drawing opening 9 are thinned at the appropriate points and, if necessary, separated, while at the points where the flats 5 act, these squeeze the process transversely to their course promote.
  • FIG. 4 shows a section through a finished connection point, which corresponds to the position of the die 1 shown.
  • FIG. 5 shows a section through the same connection point, but rotated by 90 °, ie that 7 separations 18 have been created on the inside of the point by the deep-drawing edges.
  • the first plate 15 is not affected in this separation process.
  • the deep-drawn and squeezed plate section 19 belonging to the plate 15 has the elevations 20 formed by the annular groove 12 and the longitudinal groove 13.
  • the Plate section 21 of the plastic plate 16 and the plate section 22 of the third plate 17 are by the deep-drawing edges, acc. 5, partially separated from one another, while in the other position rotated by 90 °, these plate sections 19, 21 and 22 are still fully connected to the plates 1, 16 17.

Abstract

L'invention concerne un procédé et un dispositif d'assemblage par imbrication. Dans le dispositif présenté, le poinçon de formage (1) présente une surface de travail (4, 5, 6) cunéiforme lui permettant d'effectuer différents refoulements de matière dans deux directions transversales décalées, l'une par rapport à l'autre, de 90 DEG .
