| Abstract: | The cold extruding process is one of the most economical and high efficiency technology for the gear shaft with involute-gear-tooth for transferring torque in automobile. Based on introducing the cold extrusion principle of involute-gear-tooth,the key technical problem including the dimensions and surface quality of extruding blank, choice of the main forming parameters and the fix of extruding blank in the cold extruding process, were analyzed .The choice of parameters of involute-gear-tooth for the die and the she structure of die with involute gear- tooth were describted |
