Abstract：

In order to reduce the energy loss during the forging process, a hydraulic system of forging press with a maximum output pressure of 25 MN was designed, and a parallel dual-pump hydraulic station driven by a single motor was introduced. Then, a continuous boosting circuit based on a two-way hydraulic cylinder was designed, the calculation and simulation were conducted, and the control system based on S7-200smart series PLC and analog expansion module was designed. Furthermore, the models of parallel dual-pump hydraulic station, continuous boosting circuit and hydraulic system of forging press were established by software AMESim, and the simulation analysis were conducted on them respectively. The results show that when the output pressure of hydraulic station increases to 4.9 MPa, the output flow of hydraulic station is reduced by unloading of the low-pressure and large-flow pump to avoid motor overload and overflow loss. Different output pressure values of hydraulic station are set respectively to obtain the pressure values of hydraulic station and the upper chamber of hydraulic cylinder. The calculated value of boost ratio is around four, which is basically consistent with the design boost ratio k=4, and the boost effect is obvious. The overflow loss is minimized during the pressurization and boosting process, and the energy utilization rate is improved, which provides a reference for energy-saving design of high-pressure hydraulic system.
