Definitions

  • Fig. 1 the top view is shown on a stripe image.
  • the strip material 1 is provided in a first stage with a flow preform 3, which results in fine cutting in step 2 a custom-made component 2.
  • FIGS. 5a to 5d show a similar process as in the FIGS. 2 to 4 described, except that in addition a so-called roof mold 8 is stamped. Otherwise, the same names and the same functional sequence apply to the same parts.
  • FIG. 6 shows such a tooth 10 with an impressed roof shape 8, wherein the roof shape is bordered by the two conical tooth flanks 17.
  • the roof shape acts as an insertion bevel to achieve a softer switching of the synchronizer ring, coupling body or clutch disc when inserted into a tooth gap.
  • Fig. 2 the fineblanking process is shown in section 2 in section.
  • the strip material is clamped by the device 5 at a predefined pressure.
  • Stamp 6 and ejector 7 cut after the completed pressure build-up of 5, the component 2 in the conical design of the lower part of the device 5.
  • the pre-oriented material volume through the advanced flow prominence in the area 4 allows the flow of material into held cavities 4 and thus a burr-free component.
  • Fig. 3 shows another variant.
  • a flow precursor is introduced, in the same or following stage, a specific roof shape is further introduced by flow projections.
  • the in Fig. 2 described combined fine blanks with extrusion presses for preorientation of the material in contrast to Fig. 2 does not yet represent the final contour. Only in the subsequent stage is the burr-free extruding and calibrating on the final contour of the stamped part 2 by punch 6 and lifter 7 and a die. 5
