【Abstract】 The data is obtained by using DEFORM-3D software as a simulation of the actual machining process. Based on the orthogonal test range analysis method, the research takes the forming load and the degree of die wear as the test index to optimize the bearing cap process parameters, namely the forming speed 15 mm/s, the friction coefficient of 0. 1, the initial temperature of 700℃, the die die hardness of 63 HRC.According to the optimal parameters, the effect of different factors in the extrusion process on the forming load and the wear of the die are explored. And the correctness of the orthogonal test is verified: the extrusion has a good forming effect and the processing quality of parts is improved and also the cost of trial mode is reduced, which provides reference value for the production and processing of end caps.更多还原
