Abstract：

Due to the high working pressure large flow rate and harsh working conditions of the large-tonnage hydraulic die forging hammer, the system vibrates serious, the strike frequency is low, the striking energy is inaccurate, and the return speed is relatively high, resulting in serious cylinder collision phenomenon. Therefore, for CDKA series 400 kJ counterblow hammer, the optimization target evaluation function model was constructed by dynamic analysis, and multiple sets of values were selected for simulation research on three important parameters of pressure P, rodless cavity of hydraulic cylinder D and linkage cylinder diameter d4, and the parameters of high-pressure and large-flow rate hydraulic system for counterblow hammer were optimized. The results show that the optimized parameters conbination is P=17 MPa,D=Φ300 mm，d4=Φ60 mm. The strike frequency is improved of 55 times per min, the strike energy is stabilized, the final speed of return stroke is reduced of 1.86 m·s-1, and the degree of vibration is reduced.
