Deep draw manufacturing process

摘要

A method of manufacturing a drawn panel and a die set. The method includes clamping a blank between a binder and a die that defines a cavity. A first draw punch contacts the blank in advance of a second punch that subsequently engages the blank. A central area of the blank is drawn by the first draw punch that clamps a central area of the blank against a lower die. Side areas of the blank are drawn into the cavity by the side punches while the central punch clamps the blank again the lower die.
