Abstract

PURPOSE: To easily form a square lid by lowering the other die through bringing a rubber die mounted one die into contact with the inside of a deep drawn lid, and by pressing the rubber die and expanding the same outwards.
CONSTITUTION: When a drawn lid 12 is set between an upper die 14 and a lower die 16 an urethane rubber die 15 fixed to the lower die 16 is brought into contact with the inside of the lid 12. Then the upper die 14 is lowered to press the urethane rubber die 15 and to expand the same outwards, thereby the lid 12 is extended until a space 17 of the upper die 14 and a space 18 of the lower die 16, and is formed. Then the upper die 14 is lifted to restore the pressure of the urethane rubber die 15, enabling the formed lid to be taken out of the urethane rubber die 15 in the die 16.
