Abstract

PURPOSE: To form cylindrical parts having various plural wall thicknesses with high precision in a short time, by forming plural sections having different wall thickness by performing press formings on metallic plates, and then, by performing deep drawing into a cylindrical form.
CONSTITUTION: Plural sections 11W13 having various thicknesses are formed by performing a press forming on a metallic plate 1. Then, a deep drawing is performed on the metallic plate 1 by using a lower die, in which a space corresponding to the sections having various thicknesses 11W13 is formed, and a punch, and a bottomed cylindrical part is formed. This bottomed cylindrical part is placed in a prescribed metallic die and a part near the bottom 2a is swollen outward by applying a compressive force in the axial direction of the cylindrical part 2. Thus, the cylindrical part 2 is formed to have the final shape. Moreover, a cylinder can be formed if necessary when a bottom part is removed by cutting off the part near the bottom 2a.
