[CN 201910446306.2] Electro-hydraulic Control System and Forming Process of 3000T Liquid Die Forging Hydraulic Press Title: Electro-hydraulic Control System and Forming Process of 3000T Liquid Die Forging Hydraulic Press Application Number: CN 201910446306.2 Applicant: Tianjin Tianforging Press Co., Ltd. Application Date: 2019-5-27 Patent Type: Invention Application The invention discloses an electro-hydraulic control system and forming process of 3000T liquid die forging hydraulic press, belonging to the technical field of liquid metal forming, characterized: the electro-hydraulic control system of the 3000T liquid die forging hydraulic press includes at least: a displacement sensor for detecting the position information of the slider; a pressure sensor for detecting the pressure information of the upper chamber of the master cylinder; and a PLC electrically connected with the displacement sensor and the pressure sensor. The invention is designed by the electro-liquid control system of the liquid die forging hydraulic machine, and the method of rapid forming of liquid aluminum liquid is realized by using PID algorithm as the core element of Siemens 1500 series PLC. At the same time, compared with the South Korea traditional valve-controlled liquid forging press, the proportional cartridge valve of atos can realize adjustable downward speed and smooth speed transition, which can not only improve the production rhythm, but also improve the production efficiency.
