Abstract: A three-dimensional finite element model for die spinning of a cylindrical workpiece is established and a practical spinning process of 5A06 alloy tube is simulated with the model and Marc software. The rotation of the workpiece driven by the die and the passive rotations of spinning wheels due to the friction between the spinning wheels and the workpiece are considered in this model. The distributions of stress and strain of deformation region are analyzed. The phenomena during tube spinning are simulated, such as build-up, shape distortion, diametric reduction and increment. From the simulated results, it is concluded: Consideration of the quality and efficiency of production, spinning speed should not be too large. In this study, the simulation process should not exceed 0.8mm/s the traction speed. Spinning force is direct proportional to the traction speed and inverse proportion to the tip radius. This model reprents the spinning deformation behaviors completely. Simulation results correspond with the experiments very well. ? (2013) Trans Tech Publications, Switzerland.
