摘要: A shock absorbing device in a press is formed by having a telescopically sliding member fastened to the punch plate of the press and a stopper member fastened to the die plate of the press and placing an oil of high viscosity between the post and the outer cylinder of the telescopically sliding member. This shock absorbing device damps the unloading impact produced when the punch of the press collides with a workpiece and fractures it and, thereby, abates the noise generated from the press, the tool and the workpiece.
