Vibration reduction method of four-column hydraulic press

After the four-column hydraulic press has been used for a period of time, every time it is started or stopped, it will vibrate a few times due to vibration. This will be very bad for the hydraulic press over time, and will also affect the production efficiency. The operator will also be worried when working, so There must be a way to reduce vibration.

Vibration caused by the alternating internal and external circulation of the hydraulic press process system, also known as forced vibration power, is mainly caused by external interference. The source of vibration must be eliminated first; prevent the frequency of the excitation force of the four-column hydraulic press from approaching the natural frequency of the system to avoid Resonance occurs; change the motor speed or change the spindle speed to avoid resonance; use forward contact surface accuracy, reduce the connection surface roughness, eliminate gaps, forward contact stiffness and other methods to eliminate vibration.

Vibration isolation methods can be selected to reduce the vibration of the four-column hydraulic press. The motor and the bed can be flexibly connected to isolate the vibration of the motor itself; a hydraulic buffer device can be selected to reduce the impact when components are reversed; thick rubber or wood can be selected to isolate the machine tool from the foundation. ; The anti-vibration ditch separation layer equipment can be selected to be connected to the ground to prevent surrounding vibration sources from being transmitted to the hydraulic press through the ground and foundation.
