Embodiment Construction

[0033] The technical solutions of the present invention will be clearly and completely described below through embodiments in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] The structure of the parts of the titanium alloy casing part to be corrected in this embodiment is as follows: Figures 12 to 13As shown, the material of the rectified titanium alloy casing part 11 is TC4 titanium alloy, which consists of an outer ring 11-1, an inner ring 11-2 and three spoke plates 11 connecting the outer ring 11-1 and the inner ring 11-2 -3, the radial plates are evenly distributed around the circumference of the outer ring 11-1 and the inner ring 11-2. The outer...

Abstract

The invention discloses a hot shape correction tool for titanium alloy casing parts, comprising an inner ring support, an outer ring support, first radial plate supports, second radial plate supports, third radial plate supports, outer ring press plate components, an inner ring press cover plate and a first fastening stud; in use, a radial plate in a titanium alloy casing part to be corrected, mounted on the inner ring support, is fixed through the inner ring support, the inner ring press cover plate and the first fastening stud; the radial plate in the titanium alloy casing part to be corrected is fixed through the first, second and third radial plate supports; the outer ring press plate components are mounted on the outer ring support and used to fix an outer ring in the titanium alloy casing part to be corrected, mounted in an outer ring support positioning groove. The hot shape correction tool for titanium alloy casing part allows a titanium alloy casing part of special-shaped structure to be thermally shape-corrected after being welded, the processing quality of such part is guaranteed, and the requirements of use are met.

Description

technical field [0001] The invention belongs to the technical field of parts welding and shape correction, and relates to a welding and shape correction tool, in particular to a heat treatment shape correction tool for titanium alloy casing parts. Background technique [0002] A casing part of an aero-engine such as Figure 12 , Figure 13 As shown, it is welded by an inner ring, an outer ring, and a plurality of spoke plates connecting the inner ring and the outer ring, and its material is titanium alloy. The web between the inner ring and the outer ring has a certain inclination angle, and the outer ring is a thin-walled conical cylinder. Since such parts are special-shaped parts, and the welding workload is heavy, the vertical direction of the inner ring and outer ring of the part and the angular direction of the radial plate will be greatly deformed after welding, which cannot meet the requirements of use. It is necessary to correct the shape after welding. And through...
