Abstract
PURPOSE: To eliminate the sliding plate, to reduce man-hour and to prevent the cushion from weakening, by guiding the cushion by the hollow pipe post at its outer surface of the lower die and also by guiding the guide post of the upper die by the hollow pipe post at its inner surface.
CONSTITUTION: The plate to be worked is inserted between the upper and lower dies 11, 12 and the upper die 12 is lowered. An upper guide post 13 is guided by a pipe post 14 and both the dies are brought close. The plate is pressed between a slightly projected cushion 15 from the upper surface of the lower die 11 and the upper die 12, and it is further lowered and deeply drawn and embossed etc. In the meanwhile the cushion 15 is lowered against the elastic force of an urethane rubber 19 and a sliding bush 17 of the cushion 15 is guided by the outer surface of the pipe post 14 and is slided downward. After the completion of the forming, the cushion 15 is pushed upward by the elasticity of the rubber 19 and is restored to its former position.
