In order to study the effect of different initial conditions (initial relative density, friction factor) on the compacting process of powder connecting rod forging process, the plastic deformation finite element software DEFORM-3D was used to simulate the process of powder connecting rod forging. The results show that different initial conditions have an important effect on the compacting process of powder connecting rod forging. (1) The equivalent stress of connecting rod forging process is concentrated in the shaft part, and the equivalent stress of the two ends of the connecting rod is relatively small, which indicates that the equivalent stress is uneven and the forming density is not uniform in all parts of the forging process; 2) The initial relative density of small forging forging at the end of the big rod at the end of the material can not reach the dense, the initial relative density of the preform, the final forging densification effect; (3) the greater the friction factor, connecting rod The greater the resistance of the surface material flow, the greater the size of the connecting rod is more difficult to achieve compact, indicating that the friction factor on the relative density of the rod has a greater impact on uniformity. Through the research on the influence of the densification process of the powder connecting rod, the optimization design of pre forging billet and the die and the forming rule of the powder forging rod are provided.
