Abstract
This study addresses a comprehensive model to simulate the rotary swaging process of titanium alloy (Ti-6Al-4V) rods with a small diameter. One of the most important factors that affect the heterogeneity of products is the die inlet angle. Furthermore, the axial feed at each stroke has a strong influence on the homogeneity of the workpiece. Through numerical simulation based on 3D finite element code, Qform 9, the effect of the die inlet angle on the distributions of the strain, strain rate, and neutral plane are studied. It is can be found that the heterogeneity of strain and strain rate occurs during deformation in die angles is small. The axial feed at each stroke effects slightly on the forging force but considerably on the heterogeneity of the workpiece. The results of the simulation can be used to predict the quality of products, or as a guideline for the procedure of the die design.
