[CN 201810572174.3] Parallel motion control system and control method for sliding block of hydraulic press


[CN 201810572174.3] A Hydraulic Press Slider Parallel Motion Control System and Control Method Title: A Hydraulic Press Slider Parallel Motion Control System and Control Method Application Number: CN 201810572174.3 Applicant: Nantong Forging Equipment Co., Ltd. Application Date: 2018-6-6 Patent Type: Invention Application The present invention discloses a hydraulic press slider parallel motion control system and control method, mainly including a master cylinder, used to provide thrust to drive the slider; displacement sensor, used to detect the displacement of the slider; the speed control module is used to control the movement of the master cylinder; the controller is used to collect the displacement sensor signal, execute the control algorithm and transmit the control command signal to the control element in the speed control module. The invention uses spatial coordinate conversion technology, directly for the displacement and deflection angle attitude of the hydraulic machine slider at the same time for translational motion control and active leveling control, suitable for the number of redundant hydraulic machine slider parallel control.
