Problems solved by technology

[0002] At present, the traditional processing method of shaft sleeve forgings is mostly to use forging dies to process forgings with a rectangular cross-section, and then cut the forgings into a shape close to the shape of the product before finishing. This method has large cutting allowances and waste. Disadvantages of high material and processing costs

Abstract

The invention discloses a shaft sleeve forging die structure which comprises a core roller and a main die. A forging is arranged between the core roller and the main die. The shaft sleeve forging die structure is characterized in that a convex shoulder portion protruding outwards is arranged in the middle of the core roller, a forming groove is formed in the main die, a step face is arranged in the forming groove, and a side face of the convex shoulder portion inclines towards the inner side by 1-3 degrees. The forging more similar with a product in shape is processed through the die structure, so that cutting allowance of subsequent processing is small, materials are saved, and processing cost is low; a certain calendering space is reserved for forging processing by the die, so that quality and performance of the product are guaranteed.

Description

technical field [0001] The invention belongs to forging die technology, in particular to a shaft sleeve forging die structure. Background technique [0002] At present, the traditional processing method of shaft sleeve forgings is mostly to use forging dies to process forgings with a rectangular cross-section, and then cut the forgings into a shape close to the shape of the product before finishing. This method has large cutting allowances and waste. The disadvantages of high material and processing costs. Contents of the invention [0003] The object of the present invention is to provide a mold structure for a shaft sleeve forging, which has the characteristics of material saving and low processing cost, so as to solve the above-mentioned problems existing in the processing of the shaft sleeve forging in the prior art. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A mold structure for a shaft sleeve forging, which...
