Abstract

The invention discloses an annular piece combined forging method, and belongs to the technical field of forging. The problems that two components need to be produced according to the two components, the forging cost is increased, forging energy waste is large, and raw material consumption is large are solved. According to the annular piece combined forging method, a combined production manner is used for combining the two components the same in material for forging, the method comprises the following steps that round steel is arranged in a forging die of a forging press, a first forge piece and second forge piece combined forging force piece ring blank is formed, an annular piece of a combined forging force piece is placed in a punch press to conduct recess punching, the ring blank of thecombined forging force piece is cut off, and a first forge piece blank and a second force piece blank are obtained. By means of the annular piece combined forging method, one punching waste is omitted, raw material consumption is reduced, energy consumption is reduced, the forging manual operation is reduced, the forging efficiency is improved, and output per shift is increased. In addition, the combined force piece is divided into the two components, the method for punching, cutting-off and hobbing through a lathe can be adopted for proceeding, and materials are saved to the maximum degree without procedure increasing.

Description

technical field

[0001] The invention relates to the technical field of forging, in particular to a combined forging method of a ring-shaped piece. Background technique

[0002] The early double-ring blanks generally adopt the axial split forging method. Although the process is simple, the material consumption is large due to the presence of flashes that need to be removed, and the material flow is more complicated. The structure and mechanical properties of different parts of the product are quite different. Large, it is easy to cause large processing deformation and heat treatment deformation.

[0003] Especially when two annular parts are of the same material and the user needs to supply them in pairs, the determined production process is: forging, punching, heat treatment, and turning. see figure 1 and figure 2 shown, where, figure 1 are two annular mating parts, figure 2 Forgings for two annular mating parts.

[0004] According to the conventional production tech...
