Definitions

  • the present invention relates to a device for Enforcing overlapping sheet metal parts with one Stamp and an anvil, on which at least two die parts are laterally movably supported, which delimit an opening, so that when the stamp moves into the opening dodge sideways when deforming the sheets and so a Joining point is formed.
  • This object can be achieved according to the invention in that the die parts are separated by joints that are not radial run. According to the state of the art, radial ones have always been used Gaps are provided between the die parts. In the backflow process the die parts must move outwards. This creates gaps between the die parts into which the material could dodge, so that at these points proper backflow process did not take place and this Areas did not contribute to the strength of the joining point.
  • the Grooves run at an angle to the radial direction.
  • the opening of the die has a circular cross-section , it is particularly preferred to add the joints to be arranged tangentially.
  • the opening of the die is one has circular cross-section, and the joints in shape from inward curved arches, so that the Opening like an iris can open.
  • FIGS. 1 to 5 The matrix arrangement is shown in FIGS. 1 to 5 the prior art is also shown again.
  • Figure 1 shows a currently common matrix arrangement consisting of four 300 separate matrix elements with radial joints 313, 314, 315, 316, each a quarter circle form.
  • FIG. 2 shows the same arrangement in the open state, i.e. at the end of the backflow if through the flow of the joining point, the matrix elements 313, 314, 315, 316 maximum are dispersed.
  • Figure 3 shows a joining point with the matrix device is made according to Figures 1 and 2, in plan view. It it is clearly recognizable that the joining point is not complete is round, but in the places where the individual matrix elements Bump 313 to 316 through the gap Has 300 recesses caused.
  • FIG. 4 shows a section through the joining point of the figure 3 along the line A-A. As you can see, there is the undercut there good and the joining point therefore seems to have good strength values exhibit.
  • the present invention teaches the corresponding column 300 is not radial (in the direction of flow of the backflow process).
  • a a particularly preferred embodiment is shown in FIG. 6.
  • the joints 400 are between the individual Matrix elements 413 to 416 arcuate, so that even when the die is expanded due to the backflow process cannot form columns because the individual matrix elements 413 to 416 move apart without gaps can, as shown in Figure 7.
  • FIG. 9 shows a sectional illustration through the die anvil arrangement for a die shape according to Figure 8.
  • the anvil 412 is also wider here than the maximum width of the joining point executed.
  • the L-shaped die elements 414 and 416 are attached to the side surfaces of the anvil. she are movable by a spring ring 420 and spring back elastically held in place.
  • the present invention can be done by a less complex Modification of the anvil-matrix arrangement a considerably better strength of the joining points can be achieved without for this additional work steps in the clinching process would be required.
