[CN 201710282793.4] Demoulding Control System and Control Method of Isothermal Forging Hydraulic Press Title: Demoulding Control System and Control Method of Isothermal Forging Hydraulic Press Application Number: CN 201710282793.4 Applicant: Tianjin Tianforging Press Co., Ltd. Application Date: 2017-4-26 Patent Type: Invention Application The present invention discloses a demoulding control system and control method of isothermal forging hydraulic press, including: slider displacement sensor, lower unloading cylinder displacement sensor, upper unloading cylinder displacement sensor, slider proportional cartridge, slider proportional servo valve, lower unloading cylinder proportional servo valve, upper unloading cylinder proportional servo valve, proportional pump, quantitative pump, programmable controller, it is used to read the position data of the slider and calculate the real-time speed of the slider, the position data of the lower unloading cylinder and calculate the real-time speed, the position data of the upper unloading cylinder and calculate the real-time speed, and the oil discharge flow of the proportional servo valve of the slider, the proportional servo valve of the lower unloading cylinder and the proportional servo valve of the upper unloading cylinder. The invention calculates the real-time speed of the slider according to the programmable controller through the displacement sensor data, and calculates the output proportional plug-in oil discharge and the proportional servo valve oil supply, so as to meet the requirements of the slow release control after pressing in the isothermal forging hydraulic press.
