Abstract

PURPOSE: To prevent excessive pulling-in of peripheral part into a forming die by arranging plural stoppers made of elastic material between the punch holder and blank holder and increasing pressure pad force of peripheral part of the blank in the process of drawing.
CONSTITUTION: A die 1 is lowered and the periphery 6a of a blank 6 is held by the die face 1b and blank holder 4. Forming by drawing of the blank 6 is started with descent of the die 1. In this stage, pulling of peripheral part 6a into the forming die is allowed. When the blank holder 4 comes into elastic contact with a stopper made of an elastic material and compresses the stopper 7 by pressure of the die 1 with progress of drawing, compressive reaction of the stopper 7 is added to elastic supporting reaction of the blank holder 4, and pressure pad force increases gradually and becomes greater with progress of drawing. Consequently, pulling of peripheral part 6a into the forming die almost stops. By this way, the area of blank layout of the blank 6 can be made as small as possible.
