Abstract：

The hot and cold composite forming technology was proposed to manufacture a kind of special tooth disc-hub. The hot forging process was analyzed and the process parameters were optimized by combining the orthogonal test with FEM. Regarding the reductions of the maximum forming load, the maximum damage and die wear as evaluation indexes, it was studied the influences of initial forming temperature, web thickness, the bottom blind hole height, extrusion velocity and lubricating factor on hot forging, and the suitable process parameters were obtained as follows: billet initial forming temperature 1100 ℃, web thickness 16.0 mm, the height of bottom blind hole 16.0 mm, extrusion velocity 250 mm·s-1 and lubricating factor 0.2. The technological practice shows that the optimized method can manufacture qualified hot forging parts for subsequent cold sizing process.
