Abstract：

Two different process schemes of cold forging for conductive rod were numerical simulated by finite element software Forge-3D to obtain the distribution of stress and strain and the load changes of conductive rod in different process schemes, and the optimal process scheme was selected through analysis and comparison. It is found that the die load is small and distributes uniformly in each workstation during the forging process in the second process scheme, and the produced parts have high surface quality and no defect. Furthermore, the required workstation is less to increase the production efficiency, and the objective of optimization is met. The simulation and experimental results show that the parts produced by the second process scheme are fully filled without folding burrs, which is basically in line with the numerical simulation results and also applicable to the requirements of forging industry for low loss, high dimensional accuracy and high production efficiency. Thus, the second process scheme is more suitable for this optimization objective.
