Abstract：

For the fact that some actuators in the forging hydraulic press system required high working pressure, while most of the other actuators required relatively low working pressure, a new hydraulic energy storage system based on a bidirectional supercharger was proposed. When the output oil of pump unct was pressurized by the supercharging system, the oil pressure

was significantly improved, and then together with the traditional hydraulic power unit, it supplied energy to the main working cylinder. The system overcomed the timing and periodicity of the load in the process of hydraulic press. Therefore, a motor-pump unit with lower installed power was selected in the hydraulic system design process to form a more economical and reasonable hydraulic system. The simulation results show that the output flow of the system keeps high stability and responsiveness after using the bidirectional supercharging device, and compared with the traditional hydraulic press, it has the advantages of light weight, small volume and compact structure, leading to broad application prospect.
