    摘要: According to the die cushion apparatus of a press machine (100) and the die cushion controlling method of the present invention, in holding the cushion pad (2) on standby at a desired standby position, it is possible to hold the cushion pad (2) on standby in parallel with the lower faces of the dies (202) mounted to the slide (104), and if the lower faces of the dies (202) are inclined, it is possible to hold the cushion pad (2) on standby in the state of being inclined. Through this configuration, it is possible to easily allow the material to come into contact with the lower faces of the dies (202) from the beginning of the die cushion force control (beginning of the collision), and also possible to smoothen the die cushion action in the plane, thereby enhancing the formability.

    摘要: The present invention provides a servo press system (100, 200, 300, 400) and a drawing method using the servo press system. The drawing method according to the aspect of the present invention includes: a stopping step of stopping the slide (23, 24, 26) for a first period (S 12-S22) in a course of a stroke for performing drawing; a keeping step of reducing (S16) the die cushion force to below a predetermined die cushion force and keeping (S18) the die cushion force for a second period (S18) within the first period (S12-S22) for which the slide is stopped; and a restarting step of restarting (S20, S22) the slide after keeping (S 18) the die cushion force for the second period (S 18), wherein drawing (S10-S22) including the stopping step, the keeping step, and the restarting step is performed at least one time in the course of the stroke for performing drawing.
