Shock absorption effect of four-column hydraulic press

by:WORLD     2022-10-25
WORLD Press Machine is mainly engaged in hydraulic equipment and automation equipment. As a mature product in the market, the hydraulic press is committed to the research and development, design, manufacture and after-sales of small and medium-sized hydraulic equipment in various industries. Tailor-made for users: energy-saving, exquisite and durable hydraulic equipment, the company has its own research and development team, and can provide solutions according to the parameters, process and working conditions of users' own products. Today, Shanghai WORLD Press Machine will talk to you about the shock absorption effect of the four-column hydraulic press.












1. Thicken the backing plate on the workbench: As we all know, the main reason for the vibration of the four-column multifunctional hydraulic press is the sudden release of the large energy stored in the liquid in the working cylinder. Therefore, the way to solve this problem is to try to reduce the storage capacity of the elastic compressive energy of the liquid in the working cylinder. Therefore, a backing plate of a certain thickness is added between the working table of the four-column hydraulic press and the lower die to make the working stroke of the moving beam move up, thereby reducing the volume of the upper cavity of the working cylinder when the load is suddenly lost, and correspondingly reducing the elasticity of the stored liquid energy.














2. The working cylinder and plunger of 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 descend together. The upper chamber of the cylinder enters the pressure oil and the lower chamber discharges oil, and pushes the plunger and the moving beam to press down together. When the material breaks suddenly and loses load, the upper cylinder plunger remains stationary, only the lower chamber plunger may produce downward impact, but Since the lower cylinder only needs to meet the requirements of cutting the material, the plunger stroke does not need to be large, and the volume of the upper cavity of the lower cylinder can be relatively small, so the stored liquid elastic energy is also relatively small, correspondingly reducing the impact and vibration.












3. Add a one-way throttle valve to the hydraulic control oil circuit of the hydraulic control check valve of the four-column hydraulic press. After adjusting the throttle valve, the clearance of the hydraulic control flow is controlled to reduce the movement speed of the control piston, which extends the hydraulic pressure. When the main valve of the control check valve is opened, the small unloading valve on the main spool is first opened, and then the main valve is opened, and the pressure relief time can be extended, which can eliminate vibration, impact and noise.
