Abstract

PURPOSE: To easily manufacture large-sized parts by applying a metallic soap layer to the surface of a preform formed by executing warm forging or hot forging to a stock heated to a prescribed temperature and performing a lubrication treatment, and subsequently, bringing the preform to cold press fitting in the axial direction of a die and bringing it to extrusion.
CONSTITUTION: A stock formed to a cylindrical shape is heated to a prescribed temperature, and thereafter, compressed in the vertical direction and primary forming is executed, and this stock is inserted between a male die and a female die of a forging device 2 and brought to compression forming, and pushed and expanded. Subsequently, a preform A having a tooth form Aa in the outside periphery of the stock is formed by a tooth form 6a of the lower die 6. Next, the preform A is removed by a knockout pin 10 and deburring is executed. Thereafter, by immersing the preform A successively in a sodium stearate solution from a zinc phosphate solution, a zinc stearate layer is generated. The preform A is inserted and held by the upper punch 26 and the lower punch 28 of an extrusion device 20 and led to a guide part 24b. Next, the rough shape member A is brought to extrusion to the lower part and a tooth form Ba is formed by a cutting edge part 24c. In such a way, precision working of the rough shape member can be executed easily by cold extrusion.
