Abstract：

Based on the analysis of the structure for power tools profiled output shaft, two-steps forming program of variable bearing lengths forward extrusion for profiled pole and closed upsetting for head steps was proposed. A 3-D coupled thermo-mechanical finite element model was created and analyzed by the software Deform-3D. The data of metal flows and forming load in the whole process were acquired. The simulation shows that metal flows uniformly and reasonably. Based on the simulation and calculation, the die was designed, 200 t hydraulic press was selected to be the experiment equipment and a well filling extruded part without overlap defects was obtained. The experiment and simulation demonstrate that the program is feasible.
