Study of rotating drawing process of wire rod based on slab method and FEM simulation with constant shear friction

Abstract

The study based on the slab method and FEM simulation is to explore the wire rod drawing using rotating die. Constant shear friction is assumed at the interface between die and wire rod to explore different drawing conditions such as rotating angular velocity (ω), half die angle (α°), frictional factor (m) etc. on the influence of drawing forming characteristics. Besides, the die stress of rotating die occurred has been analyzed to realize whether the drawing die is failed or not. The axial stress, the radial stress, the drawing force, and the rotating torque can be obtained from the slab method to compare with the FEM, the error between the both models is around 8-10%. Moreover the realistic experiment is able to verify the acceptances of both models. Therefore through the study due to the rotation of drawing die, the drawing force can be reduced and the flowing of wire rod is increased.
