Abstract: The floating-plug drawing deformation process of AZ31 magnesium alloy tube was simulated by Deform-3D. The influences of outer die-plug half-cone-angle matching, die bearing length and transition section length on the deformability of the floating-plug drawing were investigated. The results showed that the material displays the maximum compressive stress in the transition zone between bearing band and transition band of the outer die during the drawing process. The appropriate matching of outer die-plug cone angles can reduce the drawing force, and also improve the dimensional accuracy. The die bearing length has a great impact on the tube’s strain uniformity and the drawing force, while the transition section length affects little. Finally, the experiment verified the simulation results and confirmed the successful production of the resultant high-dimensional-accuracy AZ31 magnesium alloy pipe.
