Definitions

  • the invention relates to a method according to the preamble of the main claim.
  • This known method therefore essentially requires five successive, absolutely essential, essential processing steps, the forces to be used for the "collapse" being considerable, so that large mechanical expenditure is required to absorb these high pressures.
  • the invention has for its object to simplify the generic method in such a way that, despite less mechanical effort, the cylindrical peripheral surface formed, which is also referred to as the contact surface, has a greater wall thickness than the actual hub surface.
  • This object on which the invention is based is achieved in that the metal blank is flanged in a first process step in a departure from the previous method of operation and then the flanging is flattened to form the contact surface.
  • This mode of operation eliminates the processing of the formed that was previously required in the prior art Edge avoided and instead of the deep-drawing press producing a pot-like body, a simple border roller is used.
  • a metal blank 1 is shown, which is clamped between two chuck jaws 4 and 5 according to FIG. 1.
  • a squeeze roller 7 is shown and when the squeeze roller 7 is fed onto the border 2, the end product shown in FIG. 4 is reached, namely a support surface 3 which has a greater thickness than the hub surface 8 of the metal blank 1.
  • Grooves running in the circumferential direction can be incorporated into the bearing surface thus formed, so that, for example, a poly-V pulley is formed or it is also possible to apply transverse toothings so that a cross-toothed pulley can be created.
  • the round blank can have a thickness of 1.6 mm, it being possible to bring the contact surface 3 to a thickness of 3.2 mm by using the new method. It is known that a wall thickness increase of about 20 can be achieved even when boarding.
