Abstract：

For the complex structure characteristics of heavy-duty truck front axle, combined with the theory of metal plastic forming, the forming process of roll forging billet and die forging for the heavy-duty truck front axle was developed, and the billet sizes and the number of roll forging passes were determined by calculation. According to the reasonable forward slip value, the roll forging parts and the roll forging groove were designed, and the design of roll forging mold, bending mold, pre-forging mold and final forging mold were completed by three-dimensional parametric modeling software UG respectively. In addition, the forming process of front axle was simulated numerically by finite element software Deform-3D, and by observing the filling situation of each characteristic part in the forming process of front axle, the pressure and temperature changes during the forming process and the size comparison between the front axle forgings after forming and the actual produced front axle forgings, the rationality of forming process and mold design was verified to reduce the mold debugging period, improve the efficiency of product design and the material utilization rate, and reduce the product development cost. Finally, the designed forming process and mold for front axle were used in the actual production.
