Abstract

PURPOSE:To improve roundness as well as to prevent products from deviation of center by a method wherein disc and rib are formed first, and then, with reference to these, successive processes are to be carried out. CONSTITUTION:A circular shape blank C1 is cut out of a steel sheet and is machined and formed into a shallow cylindrical shape 1 having a relatively larger diameter by drawing. After drawn further, it is formed into a stepped cup-like cylindrical shape 4 with a rim 3. The periphery rim 3 of the stepped cup-like cylindrical shape 4 is punched off 3' for true roundness C2 to form the stepped cup-like cylindrical shape 8. Next, a U-shape groove 25 is formed in this product 8 by forming a bulge and the formed body is further compressed into a finished product 29.
