Abstract

PURPOSE: To simplify die exchanging operation and its apparatus, by placing a hydraulic cylinder between the piston and the cushion pad of an air die cushioning apparatus of the press.
CONSTITUTION: A piston 21 having hydraulic chamber 22 of which is inner hollow, is fitted to a cylinder 20 for air die cushioning apparatus of a press to slide smoothly. The second piston 23 is fitted to a hydraulic chamber 22, between of which top and the collar of a piston 21 is inserted by a spring 24. And a piston 23 is fitted with a cushion pad 26 for supporting a cushion pin via a piston rod 25. During the pressing operaton, the piston 21 is supplied by pressured oil with which the cushioning pad 26 is pushed upward, to make it perform cushioning function. When to exchange a die, the pressured oil inside of the piston 21 is returned to a tank 32 through a valve 35, and the pad 26 is lowered by the action of a spring 24.
