Abstract：

According to the forging technology requirements of high strength mechanical parts, the hydraulic system and PLC control system of die forging press with beam-column structure were designed. The hydraulic system applied a booster circuit based on the pressurized cylinder to reduce the pressure rating of system and improve the service life of hydraulic components. Then, it used the differential connection and the accumulator-based fast-motion circuit to achieve the rapid operation of hydraulic cylinder. The relief circuit which decreased pressure first and then changed direction was applied to reduce the impact of hydraulic directional change. Next,the pressure increasing circuit and the fast moving circuit were simulated by AMESim software, and the pressure of system was 10.65 MPa. After the pressure increasing circuit was pressurized, the pressure inside the hydraulic cylinder was up to 52.46 MPa, which accorded with the design requirement of the booster ratio of 5.165. The simulation results show that the system has the advantages of high pressure, quick action, supercharging effect and high automation, and meet the demand for high strength mechanical parts.
