[CN 201620292855.0] Hydraulic oil circuit system of hydraulic press


[CN 201620292855.0] Title of hydraulic oil circuit system of a hydraulic press: Application number of hydraulic oil circuit system of a hydraulic press: CN 201620292855.0 Applicant: Foshan Jufeng Hydraulic Equipment Manufacturing Co., Ltd. Application Date: 2016-4-8 Patent Type: Utility Model The utility model discloses a hydraulic oil circuit system of a hydraulic press, involving the field of machinery, it includes the main cylinder point down oil circuit, the main cylinder point up oil circuit, the lower cylinder point up oil circuit, the lower cylinder point down oil circuit, the lower cylinder point down completion oil circuit, the feeding point out oil circuit, the feeding point return oil circuit, the main hydraulic cylinder pressure increase oil circuit and the main hydraulic cylinder pressure reduction oil circuit. The hydraulic oil circuit of the utility model has good stability and reasonable design, and can realize the fast downward movement of the upper hydraulic cylinder, slow speed, it is especially suitable for a product when the lower hydraulic cylinder is pushed out and stretched, the main hydraulic cylinder can realize the function of increasing or decreasing the pressure, which greatly improves the yield of difficult products. The lower hydraulic cylinder can freely set the flow and pressure at different times in the molding process, and can not only operate inching, but also realize semi-automatic control.
