Embodiment

[0014] See figure 1 , the die forging forming method of large-scale disk-like forgings of the present invention, it first assembles the forging block 2 and the upper die 1, and then carries out the partial forming of the center of the forging 3 by cooperating the forging block 2 and the lower die 4, see figure 2 , and then unload the forging block 2 from the upper die 1, through the cooperation of the upper die 1 and the lower die 4, the edge part of the forging that has been partially formed in the center is partially formed until the forging is formed in place as a whole, see image 3 with Figure 4 , wherein the upper part of the forging block is provided with a profile that matches the cavity of the upper die, and the lower part is provided with a cavity for forming the core of the disc forging.

Abstract

The invention provides a die forging and forming method of a large-scale disc type forging piece. According to the die forging and forming method provided by the invention, the forging load can be effectively reduced, the metal flow and the forging piece die filling are facilitated, the forging heating number can be effectively reduced, the production efficiency can be increased, and the production cost can be lowered. The die forging and forming method is characterized by firstly carrying out die-forging on the center part of a local forming disc type forging piece and then carrying out die-forging on the edge part of a forming disc type forging piece until the forming disc type forging piece is integrally formed.

Description

technical field [0001] The invention relates to the field of production of large disc forgings, which is mainly used in the die forging, free forging and billet making process of large disc forgings, in particular to a die forging forming method of large disc forgings. Background technique [0002] Large-scale disc forgings are widely used, mainly in emerging fields such as wind power, nuclear power, steam turbines, ships, military industry, and aerospace. At present, in the forging process of large disc forgings, the forming and quality performance of large discs are often affected by the large load required for forging, difficult metal flow, unsatisfactory filling and many times of forging. Contents of the invention [0003] In view of the above problems, the present invention provides a die forging forming method for large disc forgings, which can effectively reduce the forging load, facilitate metal flow and forging filling, and can effectively reduce the number of for...
