[0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to cause them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes and sizes. According to the forging forming mechanism, forging can be divided into free forging, die forging, ring rolling and special forging. The forging die is a die used in the forging process. The raw material undergoes plastic deformation in the forging die under the action of external force, thereby obtaining parts of the desired shape and size.

[0003] On the one hand, die forging not only has high requirements on materials, but also has complex product shapes, which are formed by extrusion of upper and lower model cavities; on the other hand, the weight of die forgings is limited by the capacity of general die forging equipment, and the weight of die forgings generally does not exceed 70 kilograms; on the other hand, the manufacturing cycle of die forging is long and the cost is relatively high. Finally, compared with free forging, the investment cost is higher. Utility Model Content
