[0002] Forging die refers to a tool that can shape the blank into a die forging. Forging die is a key tool necessary for die forging production and plays a vital role in die forging production. Forging die is a die used in the forging process. The blank undergoes plastic deformation in the forging die under the action of external force, thereby obtaining parts of the required shape and size. Forging die can be divided into hot forging die, warm forging die and cold forging die according to the different forging temperatures. Hot forging die can also be divided into hammer forging die, screw press forging die, mechanical press forging die, flat forging die and hydraulic press forging die due to different equipment. In daily work, it is found that in the production process, the die model is single, and when different die forgings need to be forged, different forging dies need to be frequently replaced. The replacement of forging die is troublesome, the operation is cumbersome, and the production efficiency is low.
