Abstract:
Based on the structural characteristics of the power take-off transmission shaft,multi-pass extrusion technology was designed. The core processes of plastic pipe-expanding and internal spline extrusion were analyzed by the finite element software Deform-3D. The flow regulation of metallic materials and the punch load condition in the forming process were obtained. The orientation angle in front of the punch spline was increased with simulated test for several times, and the orientation angle of 60° was chosen, so that the  tear phenomenon of planning-type in the internal spline extrusion process was avoided. The small quantities production of pipe-expanding and internal spline extrusion was carried out by 200 t hydraulic press. The results show that the modified technology program of internal spline extrusion by multiple simulations is feasible. There is no planning-type tear phenomenon and defects such as wrinkles, cracks and so on.The geometry precision reaches grade IT8,and mass production will be possible.
