Definitions

  • FIG. 2 it is a clinching die very similar to that shown in Figure 1 of the above-mentioned US-A-4,972,565 is. It comprises an anvil 10 with a base 12 and roof-like beveled support surfaces 14 on which (in the exemplary embodiment: two) expanding parts 16 are supported.
  • the expansion parts 16 are with upright, approximately crescent-shaped extensions 18 in plan view Mistake.
  • stamp material in enforced the space enclosed by the extensions 18 and between the stamp and the working surface 20 of the anvil 'compressed and thus spread , the expansion parts move sideways and give space free for the lateral flow of the material.
  • the evasive movement of the Spreading parts 16 also has a downward component due to the inclination of the support surfaces 14.
  • the straight edge regions 34 lie in a line with fold lines 38 .mu.m the tab portions 40 are angled so that they are in the finished Component run perpendicular to the central section.
  • “bend” is not to be understood here as the formation of a sharp edge, but a bending radius is intentionally provided; because the component is preferred made of spring steel would cause brittle fracture without a bending radius consist. This applies mutatis mutandis to others to be described Deformation of the blank.
  • the arrows indicate the direction in which the individual parts are facing relocated to carry out the installation of the tool.
