Abstract

The invention provides a forging die of a wind turbine bearing collar. The forging die of the wind turbine bearing collar comprises a main die, a core roller and a forge piece blank arranged between the main die and the core roller. The core roller is sequentially provided with an upper sharp section, a middle section and a lower sharp section from top to bottom. The middle section is provided with a boss. The boss is located between the upper end face and the lower end face of the forge piece blank. According to the forging die of the wind turbine bearing collar, the boss is arranged on the middle section of the main die and located between the upper end face and the lower end face of the forge piece blank, so that the inner surface of a forge piece forms a groove, the boss and the groovecooperate and can effectively solve the problem that during ring rolling, the forge piece blank shifts in the die, and stable ring rolling formation can be achieved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a forging die for a wind power bearing ring. Background technique [0002] Under the action of external force, the mold makes the blank into a tool with a specific shape and size. It is widely used in blanking, forming stamping, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and engineering plastics, rubber, etc. , ceramics and other products in the molding process of compression molding or injection molding. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. However, wind power bearing rings are usually made of raw materials into regular rectangles and then processed into shapes. The metal performance of this p...
