Mass production process suitable for plate welding receivers

Abstract

The invention relates to the field of machinery, in particular to a mass production process suitable for plate welding receivers. During welding, a tool I is adopted to expand a receiver main body, sothat the outer surface of the receiver main body is bonded with the inner surface of a flange edge, the welding line quality is guaranteed, and the deformation of the receiver main body is the smallest; the end with the smaller diameter of the receiver main body is downwards; then, a tool II is lifted into the receiver main body from the top; the receiver main body and the tool II are totally heated according to a heat treatment process; the tool II drops to the bottom under the effect of gravity to achieve a shape correcting effect; when the receiver main body is machined, the receiver mainbody is clamped by adopting a tool III; the receiver main body and the flange edge are machined according to a manufacturing process, and a longitudinal mounting edge window is formed in the receivermain body; and the tool III is totally bonded with the inner wall of the receiver main body to prevent vibration of the receiver main body and cutter avoidance, so that the deformation of the receivermain body is reduced, the cutting parameters in the machining process can be doubled or higher, the machining period is shortened, and the mass production is realized.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a mass production process suitable for plate welding casings. Background technique [0002] The aero-engine is the core component of the aircraft, and the casing is the key component of the aero-engine. It belongs to the typical thin-walled structure of the casing body, and its thinnest part is only 0.55mm. Processing materials, raw material procurement costs are extremely high, so it is particularly important to control the pass rate of the main body of the casing, but the conventional manufacturing process, the processing cycle is long, the main body of the casing is deformed, and the welding area of ​​the main body of the casing is often not well controlled, resulting in The dimensional accuracy of the main body of the casing is not easy to guarantee, thereby reducing the qualified rate of the main body of the casing. [0003] Therefore, a process is currently needed to shorten the p...
