Abstract

The invention discloses an oil press piston closed-loop control system. The oil press piston closed-loop control system comprises a transformer, a switch power source module, a PID controller, a displacement detection module for detecting the displacement of a piston, a servo motor and a motor driver for driving the servo motor to run. The output end of the transformer is connected with the inputend of a switch power source, and the output end of the switch power source is electrically connected with various circuit modules. The output end of the displacement detection module is connected with the input end of the PID controller, and the output end of the PID controller is in communication connection with the motor driver. The displacement detection module is used for detecting the pistonmovement distance in the oil press running process, the difference between the piston position and the set position is calculated, and the PID controller calculates the rotation speed of the servo motor according to the difference; and the motor driver is used for controlling the rotation speed of the servo motor, accordingly, a piston closed-loop control loop is formed, and the piston positioning precision is improved. The oil press piston closed-loop control system is used for controlling the piston position of an oil press and the rotation speed of the servo motor.

Description

technical field [0001] The invention relates to the technical field of motor control, and more specifically relates to a servo motor closed-loop control system applied to a hydraulic press. Background technique [0002] As a kind of hydraulic machine, the hydraulic press uses special hydraulic oil as the working medium and the hydraulic pump as the power source. The force of the pump makes the hydraulic oil enter the piston through the hydraulic pipeline, and the hydraulic oil circulates in the oil tank through the check valve to make the piston Cycle work to complete certain mechanical actions as productivity. [0003] During the working process of the hydraulic press, whether the piston can be positioned accurately has become the criterion for judging whether the hydraulic press can accurately process the product. In the prior art, the motor configured for the pump in the hydraulic press mainly adopts an open-loop control method, and the control precision of the piston is...
