Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic presses, and in particular to a servo motor drive system. Background Art

[0002] A hydraulic press is a device that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. It relies on the force of the pump to allow the hydraulic oil to enter the cylinder or piston through the hydraulic pipeline. Then, there are seals that cooperate with each other in the cylinder or piston. These seals separate the hydraulic oil in different positions, thereby generating different pressures. These pressures can be transmitted to other actuators to achieve different process flows. The working principle of the hydraulic press is to use a hydraulic pump to convert the mechanical energy of the motor into liquid pressure energy. This pressure energy is transmitted to the actuator through a series of control elements, and then converted into mechanical energy to drive the load. In the hydraulic press, hydraulic oil is both a medium for transmitting energy and a lubricant and coolant.
