[0002] Forging is a processing method that uses pressure to make metal materials deform plastically, thereby obtaining a blank or part with certain shape, size and performance. The basic principle of forging: when external force is applied to the metal blank, the grains inside the metal will slip and rotate along the force direction. Under suitable temperature and pressure conditions, the rearrangement of these grains will gradually change the shape of the metal, and in this process, the organization of the metal material will become more compact, and the mechanical properties can also be improved. For example, forging can refine the grains of the metal, improve its strength and toughness. The application fields of forging include the mechanical manufacturing industry, the aerospace field, the shipbuilding industry, etc. During the forging process, when forging a column surface, it is necessary to ensure that the column remains horizontal and stable during the forging of the surface due to design requirements.
