Extrusion process is a type of advanced production technology,especially suitable for the processing of fine-pitch gear. This pa-per,according to the requirement of gear form and of square technology of a gear shaft,analyzes the program for extrusion process of a gear shaft,designs one shot process extrusion die structure,optimizes extrusion die structure and its processing technology,and solves the difficulties in the production of extrusion dies,replacing gear hobbing manufacturing with the gear shaft production technology,thus in-creasing the yield percent of pass by three percent,and increasing the production efficiency by five times.
