| Abstract: | The structural characteristics of a special tooth-shaped clutch hub part were analyzed. The technological difficulties in the cold compound extruding process and the key points in die designing of this kind of part were elaborated. And the die manufacturing, installation and alignment were also introduced. An optimized design was put forward targeted to tackle the existing technological problems in the compound extruding process. The optimized punch, cavity die and billet were all designed. The optimization results were verified by experiments. |
