Abstract
This study proposes a cold drawing technology of wire rod with rotating die; it carries out an FEM simulation on rotating drawing using DEFORM-3D commercial software. Frictions among the die and the wire material are assumed as constant shear friction. The effective stress, the effective strain, the velocity field, and the drawing force can be determined from the FEM simulation. In this study, effects of various drawing conditions such as the rotating angular velocity, the half die angle, the frictional factor, the die filet on the drawing forming characteristics are explored effectively. From this FEM simulation, it is noted that the rotating die effect can reduce the drawing force and increase the material flow.
