Zusammenfassung: | 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 Coulomb friction. The effective stress, the effective strain, the velocity field, various stress distributions, the die stress, the drawing force, and the rotating torque 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 coefficient, the die filet on the drawing forming characteristics are explored effectively. From this FEM simulation, it is noted that the effect of rotation die and die filet can reduce the drawing force and increase the material flow. |
