发明名称 Press having gas cylinders of plastically deformable members for even distribution of blank-holding force on pressure member through cushion pins
摘要 A press including force applying means for producing a blank-holding force, a cushion pad which receives the blank-holding force when the cushion pad is lowered, cushion pins disposed on the cushion pad, and a pressure member supported by the upper ends of the cushion pins, so that the blank-holding force is transferred to the pressure member through the cushion pins to hold a blank placed on the pressure member, when the pressure member is moved down during a pressing operation on the blank. A plurality of mutually independent balancing members, such as gas cylinders each filled with a gaseous fluid, or plastically deformable members, are disposed in respective transfer paths of the blank-holding force between the pressure member and the respective cushion pins.
