For the structure characteristics of the automobile shock absorber shell,the solutions and design route of the new process,which realized the hot extrusion integral forming by composite process of forward extrusion and lateral extrusion,were put forward by forming process analysis,and the hot extrusion die of the shock absorber shell was designed. Furthermore,the head of punch was designed as a flat bottomed cone,and the unit extrusion pressure was reduced. The die was designed as the composite structure of...
