Abstract

The invention discloses a forging method of a GH4169 alloy inner cartridge receiver special-shaped ring part. The forging method comprises the steps of sawing, upsetting, punching, chambering and rolling, wherein the forging method further comprises the step of mold formation after the rolling step. The forging method has the following beneficial effects: the forged ring part is finally formed by a mold; the subsequent machining margin of the obtained forged part is low; the material utilization rate is high; the production efficiency is high; and in addition, a mold forming process nearly damages the streamline of the forged part.

Description

technical field [0001] The invention relates to a high-temperature alloy special-shaped ring forging process, in particular to a GH4169 alloy inner casing special-shaped ring forging forming method. Background technique [0002] Superalloys have good fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, good processing performance, welding performance and long-term organizational stability, and can manufacture various parts with complex shapes. They are used in aerospace, nuclear energy, and petroleum industries. widely used in. [0003] The inner casing ring is a key component of the aircraft engine. The traditional forging process adopts rolling into a constant cross-section ring and then machining. The disadvantages of the above method are: 1. The material utilization rate is low, resulting in waste of raw materials; 2. Due to the subsequent mechanical Large machining allowance leads to low production efficiency; 3. Due to a large number o...
