Abstract
A device for fabricating a toothing at an inner facing edge of a three-dimensional pot-shaped body produced by forming and fine blanking exclusively implemented by cutting and/or shaving with a fine blanking die and/or a shaving device. The device includes a base plate and a pressure pad between which the pot-shaped body is receivable. A pilot die is received within a hollow space of a die and is biased in an advancement direction of the die such that a portion of the pilot die protrudes from the hollow space and contacts the base of said pot-shaped body before the die when the die is advanced in the working direction. A groove is thereby created between said curved edge of the pot-shaped body and the pilot die for leading a fine blanking burr or shaving chips into the recess of the pot-shaped body. Further advancement of the die fixing and pressing the burr or the chips into the recess.
