1、减少液体弹性能储存量。液体储存的弹性能与工作缸中液体的高度成正比,因此,可在四柱液压机的工作台与下模之间加厚垫板,使活动横梁工作行程上移,以减少工作缸液柱高度。也有在工作缸活塞和活动横梁之间加一个可动垫块的,即在四柱液压机空程向下时,活塞与横梁一起下降,待接触工件后,在加压之前,活塞先回程上升,此时辅助液压缸动作,将可动垫块塞入活塞与活动横梁之间。降低工作介质的压力也可以减少液体储存的能量。

2, other ways to release energy. That is, at the moment when the 100-ton four-column hydraulic press suddenly loses load, part of the high-pressure liquid in the working cylinder is quickly drained to reduce the energy to be released. This method for the liquid pressure is higher, the effect is more significant, but requires the corresponding electro-hydraulic control valve sensitivity is relatively high, but also do not cause the discharge pipe larger vibration.
3、吸收能量以减震。在100吨液压机下部设置缓冲垫,调整到材料快要切断时,在切断瞬间,运动部分接触的缓冲垫,从而将一部分能量消耗在压缩缓冲垫上。缓冲垫可以是液压缓冲,也可以是气液缓冲。
