Abstract：

According to the part drawing of steering knuckle for JMC truck provided by customer, the shape and structure of part were analyzed, and the blank size of steering knuckle was calculated by combining the existing extrusion process with the forging equipment. Then, the forging drawing of steering knuckle for JMC truck was designed, and the corresponding forging process was formulated. Furthermore, the tonnage load, pre-forging deformation temperature field and final forging material forming of steering kunckle forgings for JMC truck were simulated by the finite element numerical simulation method of Deform. According to the numerical simulation results, the actual production verification was conducted after the forging process was optimized, and the results of finite element numerical simulation were compared with the actual conditions of pre-production to verify the authenticity of the research results. Thus, the reliability of forging production is ensured, the internal quality of forgings is improved, the life of forging dies is extended significantly, the cost of mold repair is reduced, and the forging output is increased from 900 pieces to 1100 pieces, which provides a useful reference for the development of new products with similar structure.
