Abstract

PURPOSE: To enable pressure forming to be done by one process by dividedly disposing press dies to trough parts, crest parts and protrusion parts.
CONSTITUTION: A bottom part N is held by a trough part holding die 1. Next, a crest part press die 2 and protrusion part press die 4 are simultaneously pressed in the perpendicular direction to perform enclosing of the end parts in the longitudinal direction of a deck plate P. At the same time, a handle part H and an anti-falling protrusion part B are formed. The handle part H is deep drawn. The anti-falling protrusion part B is formed as the protrusion part press die 4 set in the trough part holding die 1 moves cooperatively with the pressing down of the crest part press die 2 and the protrusion part B is worked by the protrusion part receiving die 5.
