一、在框式液压机的工作台上加厚垫板，大家都知道引起液压机振动的主要原因是工作缸中液体储存的A sudden release of greater energy. Therefore, the way to solve this problem is to try to reduce the storage amount of liquid elastic compression energy in the working cylinder.
2., the working cylinder and plunger of the frame hydraulic press using the tandem plunger hydraulic press are divided into upper and lower sections. When the idle stroke is downward, the upper and lower plungers and the moving beam一起下降;接触工件后，四柱液压机上缸进排油口关闭，但下缸上腔进压力油下腔排油，推动柱塞及动粱一起下压。
When the material breaks and suddenly loses load, the plunger of the upper cylinder remains stationary, and only the plunger of the lower chamber may produce downward impact. However, since the lower cylinder only needs to meet the requirements of cutting off the materialThe plunger stroke does not need to be large, and the volume of the upper cavity of the lower cylinder can also be relatively small, so the elastic energy of the stored liquid is also relatively small, which correspondingly reduces the impact vibration
