Abstract：

Based on the cold pushing process of Ф219 mm×5 mm TA2 elbow, a finite element mode was established by the Deform-3D software. The virtual orthogonal experiment was numerically simulated, in which the clearance between the tube and the mandrel, the clearance between the tube and the die and the friction coefficient were regarded as influential factors while the average of wall thickness of formed below and the ellipticity of cross-section were chosen as the evaluation index. The influential regularities of different parameters on cold pushing were obtained and optimized parameters were obtained with clearance 1.0 mm and friction coefficient 0.06. The verifying experiment shows that the results of the numerical simulation of orthogonal experiment are accurate and effective, and the elbow quality requirements are met.
