Process method for improving machining quality of annular part with honeycomb

Abstract

The invention relates to a process method for improving the machining quality of an annular part with a honeycomb. The process method is characterized by comprising the following steps that machiningcontents before and after honeycomb welding are determined, firstly, the machining position of the upper end surface of the honeycomb of the part is determined, the honeycomb upper end face is processed to the design size after honeycomb welding is adjusted to be processed to the design size before honeycomb welding, so that the problem that in the post-welding machining process, due to the fact that the honeycomb heights are inconsistent, the honeycomb is locally collided or cannot be machined to the size required by design is solved; except the upper end surface and the mounting surface of the honeycomb, the rest surfaces are combined and machined to the final size after the honeycomb is welded. The process method for improving the machining quality of the annular part with the honeycombhas the advantages that the process method is already applied to similar parts of other types of engines, the qualified rate of the parts is increased to 100% from 71% before application, and the economic benefit is greatly improved.

Description

technical field [0001] The invention relates to the field of machining, in particular to a process method for improving the machining quality of an annular part with a honeycomb. Background technique [0002] There are a large number of thin-walled ring parts with honeycombs in the engine components, and the deformation after welding is always the bottleneck problem in the manufacturing process of such parts. The inner ring parts of the guide vane are also one of the thin-walled ring parts with honeycomb. The structure is complex, the wall is thin, the rigidity is poor, and the precision is high; the material removal amount is large during processing, the processing stress is large, and the processing is easy to deform, especially with honeycomb. The thin-walled annular parts also need brazing honeycomb and aging process, the temperature is high, and the deformation after welding and aging is large, which brings great difficulty to subsequent machining, and the quality of th...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the honeycomb end face jumps greatly due to welding deformation of the thin-walled annular parts with honeycomb, which causes the processing of the upper end face of the honeycomb to be unqualified or even damage the honeycomb. Content), adding auxiliary process steps to improve clamping stability and other improvement measures, and verifying them, so that the parts meet the design requirements, solve the problems of low processing pass rate and poor economy, and provide a special way to improve the processing quality of ring parts with honeycomb Process method
