After the four column hydraulic press has been used for a period of time, each time it is started or stopped, there will be a few bumps due to the vibration, which is not good for the hydraulic press and affects the production efficiency.
Due to the internal or external periodic alternation of the hydraulic press process system, the vibration caused by the excitation force, also known as forced vibration work, is mostly caused by external interference. In order to eliminate it, first find the vibration source; to prevent the frequency of the excitation force of the four column hydraulic press close to the natural frequency of the system, so as to prevent resonance, replace the speed of the motor or change the speed of the main shaft of the hydraulic press In order to eliminate the vibration, the accuracy of the contact surface, the roughness of the contact surface, the clearance and the forward contact stiffness are used to eliminate the vibration.
It is necessary to reduce or eliminate the exciting force of vibration source. It is necessary to balance the parts with rotating speed above 600r / min, especially for the parts with high-speed rotation, the manufacturing accuracy and device accuracy of the forward gear of the four column hydraulic press, especially the working stability accuracy of the forward gear, and then reduce the vibration caused by periodic impact and reduce the noise; the manufacturing and installation precision of the forward rolling bearing In order to reduce the vibration caused by the shortcomings of rolling bearing, the transmission belt with uniform length and thickness is selected.
Four column hydraulic press can choose hydraulic buffer equipment to reduce the impact of parts when reversing.
