A method for manufacturing a ring-shaped special-shaped part composed of various alloy materials

Abstract

The invention belongs to the technical field of forging manufacture, and specifically discloses a method for manufacturing an annular special-shaped part composed of alloy materials. In the present invention, the thin-walled ring parts are first obtained by processing the blank, and then the strength performance test is carried out based on the stress analysis. According to the obtained strength data, carbon steel materials with different carbon contents are used for 3D printing to manufacture multiple ring-shaped different hook parts. A plurality of ring-shaped different hook parts are fixedly connected to the thin-walled ring part to obtain a complete ring-shaped special-shaped part. The invention solves the disadvantages of the current ring-shaped special-shaped parts, such as the complex structure of high ribs, branch buds, and special-shaped protrusions protruding from the surface of the base body in the manufacturing process, as well as the use and waste of expensive metal materials in the forging process. The combination of 3D printing technology and different alloy materials can produce ring shaped parts quickly, at low cost and with high performance.

Description

technical field [0001] The invention relates to the technical field of forging manufacture, in particular to a method for manufacturing a ring-shaped special-shaped part composed of various alloy materials. Background technique [0002] With the development of aviation, aerospace, weapons, national defense science and industry and other fields, the amount of high-performance difficult-to-machine metal key components is increasing, and the processing of aerospace parts such as engine disks, shaft parts, turbine casings, and landing gears is difficult. keep growing. These complex structures usually adopt ingot casting, billet making, mold manufacturing, forging, machining and other processes, with large processing volume, low material utilization rate and extremely high cost. Forgings in the traditional forging field are all forged with the same alloy material, especially in complex structures, when the overall material is forged with expensive alloy materials, some parts wit...

These complex structures usually adopt processes such as ingot casting, billet making, mold manufacturing, forging, machining, etc., with large processing volume, low material utilization rate and extremely high cost

Forgings in the traditional forging field are all forged with the same alloy material, especially in complex structures, when the overall material is forged with expensive alloy materials, some parts with weaker strength requirements are also made of the same expensive material , which causes a waste of resources and brings high manufacturing costs to enterprises. At the same time, forgings with complex structures are limited by the forging process in the manufacturing process, and it is difficult to produce them completely.
