Description

Technical Field

[0001] The utility model relates to the technical field of forging dies, in particular to a large-scale annular forging die. Background Art

[0002] Ring forgings are a product of the forging industry. They are a type of forgings. They are made by applying external force to metal billets (excluding plates) and forming them into ring-shaped objects with appropriate compression force through plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process builds a refined grain structure and improves the physical properties of the metal. Ring forgings can be seen everywhere in daily life and are an industrial product.

[0003] Large ring forgings need to be shaped using forging dies during the forging process. Currently, when large ring forging dies are used, they are placed on the die table with manual assistance. Manual placement of ring forgings relies on manual experience to place the ring forgings at the center of the die table. Although this achieves the placement of the ring forgings, it is not convenient to place the ring forgings at the center of the die table when placing the ring forgings, which affects the forging quality of the ring forgings. Therefore, it is necessary to design a forging die for large ring forgings. Utility Model Content
