Device for fabricating a toothing at a three-dimensional body produced by forming and fine blanking

A device for forming teeth into a curved edge of a pot-shaped body extending to an inner side of the pot-shaped body, said pot-shaped body including a recess adjacent to said curved edge, the device comprising:

• a base plate on which the pot-shaped body is restable;
• a pressure pad contactable with a top edge of the pot-shaped body such that said pot-shaped body is fixable between said base plate and said pressure pad;
• a die for fine blanking or shaving, said die including a hollow space;
• and
• a pilot die being received within said hollow space and slidable in a working direction of the die, said sliding pilot die being engageable with a base of the pot-shaped body, said pilot die being biased in said working direction such that a portion of said pilot die protrudes from said hollow space and contacts the base of said pot-shaped body before said die when said die is advanced in the working direction thereby creating a groove 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.
