Embodiment 1

[0061] Forged by die forging Figure 1a The parts shown in are described as examples, as follows:

[0062] Figure 1a The part shown in is a disc-shaped part with the dotted line as the center of rotation.

[0063] Such as Figure 1a , design the final forging model according to the part drawing according to the principle of small margin design (make the forging model as close as possible to the part and make the forging size as small as possible), such as Figure 1c ; According to the principle of easy forming and no need for machining, the prefabricated model is obtained, such as Figure 1b .

Abstract

The invention discloses a method for controlling forging deformation of a complex plate-like die forging. By setting step structures on a preform model and a final forging model, when the forging is formed, about the step structure corresponding to a final forging forming die and the step structure provided on the preform model, two or more deformation fulcrums are formed between the final forgingforming die and the perform at the corresponding step structure position. By providing a plurality of deformation fulcrums on an insufficient deformation area, the deformation amount of the insufficient deformation area can be greatly increased when forming the perform, thereby greatly reducing the design amount of the forging remaining blocks, reducing the raw materials required for the forging,and reducing the forging cost while ensuring the deformation amount during the forming process of the forging.

Description

technical field [0001] The invention relates to the technical field of forging technology, in particular to a method for controlling the amount of forging deformation of a complex disc cake internal die forging. Background technique [0002] In order to meet the weight reduction requirements of aerospace stress-bearing parts, in recent years, more and more aerospace disk cake-type stress-bearing parts are designed as complex integral parts. This kind of pancake integral part is not only complex in shape, but also requires no less microstructure morphology and macroscopic mechanical properties than ordinary shape parts. In order to ensure that the microstructure and macroscopic mechanical properties of complex pancake parts meet the requirements of use, in the process of designing and forging corresponding integral forgings, especially in the process of forging complex pancake forgings of titanium alloys and superalloys, it is generally necessary to Strictly control the unif...
