Abstract

The invention discloses a method for controlling the amount of forging deformation of a complex plate-type die forging. By setting a step structure on the preform model and the final forging model, when the forging is formed, the corresponding step structure of the final forging forming mold and the preform The step structure set on the model forms two or more deformation fulcrums at the corresponding step structure positions between the final forging forming die and the preform; by setting multiple deformation fulcrums in the insufficiently deformed area, the prefabrication can be greatly increased. The amount of deformation in the area where the deformation amount is insufficient during billet forming can greatly reduce the design amount of the remaining block of the forging while ensuring the amount of deformation during the forming process of the forging, reducing the raw materials required for forging forging and reducing the forging cost.

Description

technical field [0001] The invention relates to the technical field of forging technology, in particular to a method for controlling the forging deformation of a complex pancake inner die forging. Background technique [0002] In order to meet the weight reduction requirements of aerospace force-bearing parts, in recent years, aerospace pancake force-bearing parts are increasingly designed as complex integral parts. This kind of pancake integral parts not only have complex shapes, but also require no less than ordinary shape parts for their microstructure and macroscopic mechanical properties. In order to ensure that the complex pancake integral parts meet the requirements in terms of microstructure and macroscopic mechanical properties, 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 uniformity of the d...
