DIE CUSHION APPARATUS OF PRESS MACHINE AND DIE CUSHION CONTROLLING METHOD

摘要

According to the die cushion and die cushion controlling method of the invention of a press (100), in terms of the vacancy needed for one keeps standby cushion (2), it can keep standby cushion (2), it is parallel with below the mold (202) for being installed to sliding (104), it can be that inclined state keeps standby cushion (2) if being inclined below mold (202). It is configured by this, can easily allow that material contacts below same mold (202) since die-cushion force controlled (collision) is just and the possible die-cushion action made in the planes is smooth, therefore improve formability.
