It must be shaped to hot forging axle trucks and large buses by swaging, to ensure the strength and fatigue life of the index components. Hot forging, a forging technology, generally refers to the metal blank is heated to a temperature above the recrystallization temperature of the material, the use of metal mold plastic forming blank forging method for precision forging shapes and sizes. Now, 120 MN hot die forging press die forging of automobile front axle production process as a whole is becoming more common, and improve the level of technology and die design. But in order to improve product quality and reduce production costs, for more than 95 kg of truck front axle and truck front axle, many difficulties and problems still exist in the process of production. This article is based on a typical truck front axle as an object, to analyze and introduce G312 die forging technology and die design of automobile front axle.
