Definitions

  • bowls for motor vehicle wheels is usually made of boards, which in turn are punched out or burned out of strip material or wide flat steel.
  • the material waste is very high and is about 35 to 40%.
  • a cylindrical bandage is produced, from which a calotte is then produced by orbital pressing.
  • the bowl bottom is preformed. Subsequently, in a conventional manner, the completion of the bowl.
  • Another method is the rolling and welding of a full circular ring.
  • the invention has for its object to simplify the manufacturing process.
  • the rejuvenation or strain hardening of the material is already achieved in the strip, before the first forming, by rolling.
  • Strip is tapered on one side by means of conical rollers, so that a curved part is formed.
  • Significant difference from the prior art, however, is that no circular ring is produced, with a circumference of nearly 360 °, but a pitch circle ring whose circumference is between 130 ° -310 °, preferably at 180 °.
  • this Tellnikring is formed by rounding into a closed ring, thereby creating a conical bandage immediately, which is then welded.
  • bandage produced in this way can be formed by simple pressing operations, both the bottom of the bowl (hub flange) and the bowl pot.
  • the prerequisite for the bottom of the bowl is that this area is already preformed, ie when rolling the strip between the conical rollers, a material thickness taper occurs on the outer side of the strip depending on the desired transformation between 20% and 50%.
  • the circumference of the pitch ring is between 130 ° and 310 °.
  • the further work sequence corresponds to the current production method
  • the effect of the new process is a material saving of about 38% compared to the currently practiced process.
  • the starting product is a strip of coil or Breüfiachstahl the specified dimension. This is conically rolled out by tapered rollers and at the same time deformed into a bow or partial circle ring.
  • the pitch ring has a circumference of 180 °, but in any case significantly less than 360 ° ( Fig.2 ).
  • the bottom of the bowl (hub flange) is pre-pressed under a press and the radius between the bottom of the bowl and the bowl of the bowl is carried out in accordance with the finished size ( Figure 5 ).
  • the folding of the bowl bottom can be done under a press or on a flow-forming machine.
  • the final pressing of the hub flange can be done directly in the conical bandage in a pressing operation.
