摘要： A pressing machine 1 includes: a bed 6 on which a die-cushion device 10 is provided; and a bolster 51 provided on the bed 6. The bed 6 has an inner space 61 in which a die-cushion pad 13 of the die-cushion device 10 is lifted up and down. A supporting portion 63 penetrating the die-cushion pad 13 in a lifting direction and supporting a lower surface of the bolster 51 via a carrier 52 is provided in the inner space 61. With this arrangement, since the bolster 51 is supported by the supporting portion 63, the bolster 51 can be prevented from being flexed during a press forming operation, whereby a highly accurate press forming operation can be realized. In addition, since the supporting portion 63 penetrates the die-cushion pad 13, unlike conventional arrangements, the die-cushion pad 13 does not need to be divided, whereby a complication of the arrangement can be avoided.

摘要： A die cushion pad 13 is divided into four small pads 15 and a large pad 16. With this arrangement, a load applied to an action point of each of the small pads 15 can be equalized by the large pad 16, and an overturning moment arising between the action point and a reaction force point that equates the center of the small pad 15 can be canceled, thereby preventing flexure of the small pad 15. Accordingly, since flexure of the cushion pin and the like can be prevented, there is no risk that the cushion pin is frictioned against the penetrating hole of a bolster, and the lifting operation can be smoothly performed, whereby a higher-accuracy pressing forming operation can be realized.
摘要翻译：模具缓冲垫13被分成四个小垫片15和大垫片16。通过这种布置，施加到每个小焊盘15的作用点的负载可以被大焊盘16相等，并且在作用点和反作用力点之间产生的翻转力矩等于小垫15的中心可以取消，从而防止小垫15的弯曲。因此，由于可以防止缓冲销等的挠曲，所以不会有缓冲销与垫圈的贯通孔摩擦的风险，能够平稳地进行提升作业，能够进行更高精度的冲压加工可以实现。
