I Preliminary step of cold forging to avoid deformation 1! II. The cylindrical rough material 11 is subjected to annealing a5J and a71 smoothing treatment. Finally, as shown in FIG. 9, a cylindrical blank material 11 is extruded from a predetermined press 1 and 12C. This press machine 12 is equipped with a hole 13 having the above-mentioned circle 4] rough material 11 (!: 内1■J), and a hole 14 formed around the inner circumference of the hole 13 corresponding to the hole 14 formed on the outside of the workpiece. gear cutting protrusion 1
A die 16 with a hole 11 formed in the center of the workpiece and a round 41-shaped force untabundge 18 coaxially installed in the center of the hole 13, and a die 16 with From the workpiece, the straw cylindrical rough material 11 is
414 is made from pan J19 which is extruded to -h. A cup-shaped forged product 20 having a radius 14 on the outer periphery is formed by the extrusion process. Next, as shown in FIG. 10, in which both axial ends of the cup-shaped forged product 20 are cut, one cylindrical tooth core 21 is formed. Next, carburizing method (solid carburizing method, liquid carburizing method)
The resistance of the cylindrical tooth width 21 is improved by surface treatment such as carburization vA) or cyanidation method. Suritake Ei 1 strengthens the sadness.
