METHOD AND DEVICE FOR FABRICATING A TOOTHING AT A THREE-DIMENSIONAL BODY PRODUCED BY FORMING AND FINE BLANKING

摘要

A method and device for fabricating tooth at a three-dimensional body produced by forming and fine blanking is provided to increase stability of processes by removing a thermal treatment. In a method and device for fabricating tooth at a three-dimensional body produced by forming and fine blanking, a flat strip by forming and fine blanking in a tool is formed into a pot-shaped body(1) placed in the base of the body inner forms like impressions and/or projections and/or indentations and/or recesses and/or sinks and/or holes and/or pivots and a substantially evenly curved edge and afterwards the edge is fabricated into a toothing radially extending to the inner side of the body. The toothing in the edge of the pot-shaped body is exclusively produced by cutting or shaving with a fine blanking die(12) or a shaving device. A burr or shaving chips developing during cutting or shaving is pressed into a recess in the base of the pot-shaped body allocated to the toothing.
