[CN 201810251170.5] Free forging hydraulic press with high efficiency transmission


[CN 201810251170.5] Title of a high-efficiency free forging hydraulic press: Application number of a high-efficiency free forging hydraulic press: CN 201810251170.5 Applicant: Zhongke Juxin Jieneng Hot Forging Equipment Research and Development Co., Ltd. Application Date: 2018-3-26 Patent Type: Application for the Invention The present invention relates to a high-efficiency free forging hydraulic press, including a hydraulic cylinder, a main hydraulic pump and a booster energy storage device. In the present invention, two sets of pressurized energy storage devices are arranged between the hydraulic pump and the hydraulic cylinder of the free forging hydraulic press. The two sets of pressurized energy storage devices alternately provide equal pressure or pressurized pressure to the hydraulic cylinder of the free forging hydraulic press through the control system. After the pressure oil, the hydraulic cylinder in the free forging hydraulic press can obtain the beneficial effect of two kinds of pressure hydraulic oil, and realize the purpose of residual energy storage and efficient transmission of the hydraulic machine. The invention has the advantages of reasonable resource allocation, simple setting structure, good supercharging effect, and significant energy saving and consumption reduction.
