Abstract

PURPOSE:To avoid the generation of crack and wrinkle, to improve the yield of a material and to reduce the material cost by forming a bulging part on the part corresponding to the part becoming of the recess of a side wall of the blank circumferential part. CONSTITUTION:The punching shape of a blank 10 is set so that the peripheral edge 14 of the blank 10 becomes parallel on the boundary (alternate long and two short dashes line) of the zone 12 pressed by a wrinkle presser at drawing time and punched. In succession a bulging part 18 is formed on the segmental zone 16 elongated with the progress of drawing. Thereafter, drawing is executed on the center of the blank in the state of constraining the zone 12 together with the bulging part by a die, wrinkle presser, etc., and a container-like part 100 is formed. According to the progress of the drawing, the material of the zone 12 is pulled in the slope line direction for the peripheral edge 14, the bulging part 18 is pulled in and the bulging part is eliminated. Consequently the generation of crack and wrinkle is evaded and the material yield can be improved.
