Abstract：

Because of the shape,the clutch gears can not be processed by cutting,electrolytic process is adoptedTherefore, the productivity is very low , precision and service life of the gears are very bad and the depleted electrolyte pollutes environment.A practical die structure is presented for a hot precision forging the clutch gears in this treatise It describes the important points of the die design and assembly A powerful die separator on the die forces the forge piece to break away from male die as soon as the hammering is over.The key technical problems that the hot forge piece sticks to the male die are solved The improvement on technique and the economic benefit are very remarkable.
