Cushion pin, wear plate, load supporting device, die cushion, press machine and pressing method

摘要

An elastic member is disposed on a load supporting device such as cushion pins and wear plates, which are placed between at least a work and a die cushion pad and transfer a load applied to the work to the die cushion pad, to support the load. The load supporting device is disposed in two or more on the die cushion pad to realize equalization of the load applied to a die cushion. Thus, use of a conventional large-scale hydraulic circuit is eliminated, and the device can be simplified. And, the press machine can be produced at a low cost.
