Abstract：

In order to solve the problems of insufficient filling and heavy punch load in the multi-directional die forging of four-way valve body in actual production, the filling process of four-way valve body was simulated numerically by finite element software DEFORM-3D, and the influences of feed speed of horizontal punch, feed speed of vertical punch and heating temperature of blank on the temperature distribution of forgings were studied through the simulation results. At the same time, in order to obtain the optimal parameters, the influences of the feed speed of horizontal punch, the feed speed of vertical punch and the heating temperature of blank on the quality of four-way valve body were studied by the control variable method. The results show that the reasonable choice of feed speed for punch and heating temperature of blank avoids the excessive difference of local velocity or uneven temperature distribution in the forming process of forgings, so as to avoid the generation of stress in the cooling process of forgings and effectively improve the quality of forgings. Thus, the optimal hot forging process parameters are obtained with the feed speed of horizontal punch for 7 mm·s-1, the feed speed of vertical punch for 18 mm·s-1, and the heating temperature of blank for 1050 ℃.
