Die structure for producing race for large mine car wheel

Abstract

The invention discloses a die structure for producing a rack for a large mine car wheel. The die structure comprises a core roller and a main die. A forge piece is arranged between the core roller and the main die, the middle of the core roller is a cylindrical section of a cylinder structure, an upper shoulder portion and a lower shoulder portion are arranged on the cylindrical section, and a groove is formed between the upper shoulder portion and the lower shoulder portion. The upper end face of the upper shoulder portion inclines downwards, the lower end face of the upper shoulder portion inclines upwards, the upper end face of the lower shoulder portion inclines downwards, and the side face of the lower shoulder portion inclines outwards from top to bottom. The side face of the main die is a vertical face. A holding roller device is further arranged, and a boss is arranged on the top of a holding roller. The die structure is used for machining the race forge piece for the large mine car wheel, consumption of materials is reduced, preparation is made for subsequent thermal treatment, and the quality and performance of products are guaranteed; two-station ring rolling is achieved, secondary remelting is avoided, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of forging dies, and in particular relates to a die structure for producing large mine wheel seat rings. Background technique [0002] The shape of forgings for large mine wheels is complex, and the inner diameter of the product parts is very deep. In order to get as close as possible to the parts and reduce the forging allowance, the depth of the forgings is also large, and the ring rolling is difficult, which requires a large pressing force. And it needs to be preformed. At present, the traditional processing method of large-scale mining wheel seat ring forgings is mostly to process forgings with a rectangular cross-section with a forging die, and then cut the forgings into a shape close to the shape of the product before finishing. This method has cutting residues. The shortcomings of large quantity, waste of materials, and high processing costs. Contents of the invention [0003] The technical proble...
