Definitions

  • the present invention relates to a novel method for producing single-sided and double-sided ribbed discs, ie discs with a rib profile on one or both sides of the disc.
  • a disadvantage of this prior art is the relatively complex and therefore expensive manufacturing process, which was previously required for these discs. Common practice in mass production of these parts is the embossing of the rib profile. So far, only by using this manufacturing process can achieve an optimum rib contour, which is essential for the desired backup function.
  • this object is achieved in that the rib profile is produced by rolling.
  • the contour can be embossed either in advance in the raw material and then on the smooth punched disc.
  • a particularly efficient method of production preferably results when the rolling of the rib profile is effected by two synchronously running rollers or roller segments. Rollers (pairs) but also roll segments can be used for embossing.
  • the template for the rib profile can be recessed or raised on the rollers.
  • the production of the dials by rolling the profile is preferably carried out by embossing rollers.
  • the tools and devices for this manufacturing process according to the invention are significantly less expensive than the tools and devices required for the stamping process of the prior art.
  • the design of the rib profile can be done by two synchronously running roles.
  • the ribbed contour can be both recessed and raised mounted on the rollers.
  • the punching of the discs takes place.
  • discs of any desired inner and outer diameter can be produced from the same material already provided with the required ribs. This can be used for the cost-effective production of small quantities.
  • the disc profiles are arranged several times next to each other to minimize material consumption. Another manufacturing possibility is obtained by the discs are first punched out and then fed in the correct position a pair of profile rollers.
  • Another advantage of the manufacturing method according to the invention is a more uniform rib contour on both sides of the lock washers, if both sides ribbed discs to be produced. While the rib contour is completely rounded on embossed, ribbed discs on both sides, a slight flattening of the rib radius can be recognized due to the embossing process on the opposite side. Although this flattening can be kept within the required tolerance limits according to the prior art. Nevertheless, this leads to small variations in the assembly. In the present invention rolled version of the ribbed ribs on both sides of the rib profile is equally well rounded on both sides.
