Abstract

The invention relates to a processing method of integral guide apparatus. The processing method comprises the following steps: processing preparation: a front mounting edge, blades and a rear mounting edge are preassembled, and the blades are numbered in sequence; electron beam welding; assembly and fixing: a brazing material is prearranged; vacuum brazing: the surface, making contact with components, of each clamp for component welding is brushed with a welding stop flux; then the components are placed on a clamp base plate with the rear mounting edge facing downwards, and an interval between the bottom surface of the inner edge plate of each blade and the clamp base plate is not larger than 0.10 mm; two ring clamps with spigots are arranged on inner rings and outer rings of the components respectively, the clamped and fixed components are placed into a vacuum furnace together with the clamps for brazing, and stress-relief heat treatment of bellows components is performed simultaneously; combined machining. The processing method thoroughly solves the problem that part of brazing joints on the inner edge plates of the blades crack during processing of the integral guide apparatus, the component machining stress is small, and the dimensions are precise; the manufacture cost is reduced, and the processing efficiency is increased.

Description

technical field [0001] The invention relates to a manufacturing technology of an aero-engine, in particular to a processing method of an integral guide. Background technique [0002] The integral guide is an important part of the aero-engine. It is mainly composed of front mounting edge, rear mounting edge, blade assembly (18 pieces), bellows, and bellows front ring. The material of the parts is nickel-based superalloy. The processing and manufacturing of the guide It is mainly completed by welding and machining. The original processing process of the integral guide is: single-piece machining, brazing between the blade edge plates and between the blade edge plates and the front and rear mounting edges, intermediate machining datum, argon arc welding bellows and machining process parts , heat treatment for stress relief, and combined machining; the common problem in the process of processing multiple guides according to this process is that the inner edge of the blade of the...
