[CN 201621241259.6] Hydraulic Circuit for Independent Oil Supplement of Hydraulic Fast Forging Machine


[CN 201621241259.6] Title of hydraulic circuit for independent oil replenishment of hydraulic fast forging machine: Application number of hydraulic circuit for independent oil replenishment of hydraulic fast forging machine: CN 201621241259.6 Applicant: Jiangsu Huawei Machinery Manufacturing Co., Ltd. Application Date: 2016-11-21 Patent Type: Utility Model The utility model relates to a hydraulic circuit for independent oil replenishment of hydraulic fast forging machine, with a pipeline between the main hydraulic cylinder and the oil tank, an unloading valve is set on the pipeline to quickly reduce the pressure in the main hydraulic cylinder; a filling valve is set on the connecting pipe between the main hydraulic cylinder and the filling tank, and the hydraulic oil in the filling tank is high-pressure oil. When the oil pressure in the main hydraulic cylinder is lower than the oil pressure in the filling tank, the main hydraulic cylinder can be quickly and independently replenished. It changes the working mode of filling tank and hydraulic pump in the traditional hydraulic circuit at the same time, avoids the shortcomings of slow speed caused by air suction, and realizes the beneficial effects of energy saving, stability and high efficiency of the system.
