In this paper, cold closed\|die extrusion forging technology of the bevel gears were researched experimentally. The 3\|D numerical simulation was successively applied to analyze the forming processes and hydraulic die\|shelf was specially designed and manufactured for the cold precision forming of the gears. The results show that design in the technology and die cavity is effective,numerical simulation is satisfactory, die\|shelf system has functional reliability and load can be assigned reasonably to closing die and extrusion. They would be valuable for applying the technique to practical production.
