Embodiment Construction

[0009] Such as figure 1 As shown, put the titanium alloy spoke structure welded casing on the base 1, press the inner cover 2, install the upper limit sleeve 3, put the gland 4, insert the wedge 5, and complete the assembly of parts. During heat treatment correction, the inner diameter of the upper and lower ends of the outer casing 7 is corrected by the bulging force generated under high temperature on the base 1 and the upper and lower positioning spigots on the base 1, and the inner positioning spigot on the base 1 and the inner cover 2 positioning spigot 1. The bulging force is generated at high temperature to correct the inner diameter of the upper and lower ends of the inner casing 8. At the same time, the base 1, the inner cover 2 and the gland 4 are connected by the mandrel 6. During the heat treatment process, the inner casing 8 and the outer casing are always maintained 7 coaxiality. The limit sleeve 3 exerts gravity on the inner casing 8 through the gland 4 and the...

Abstract

The invention relates to a device for performing heat treatment correction on a titanium alloy spoke structure welded case. According to the technical scheme, the device for performing heat treatment correction on the titanium alloy spoke structure welded case comprises a base, a central spindle, an inner cover, a limiting sleeve, a gland and a wedge block. The invention aims to perform heat treatment correction on the titanium alloy spoke structure welded case by utilizing the bulging force and gravity of the device, a supporting plate is limited to shrink to drive an inner case to move up during the heat treatment correction, and the titanium alloy spoke structure welded case is enabled to meet the requirement of design paper through one-step heat treatment correction.

Description

technical field [0001] The invention relates to a device, in particular to a device for heat treatment correction of a titanium alloy spoke structure welding casing. Background technique [0002] In order to pursue a higher thrust-to-weight ratio and reduce the overall weight of the engine, the new aero-engine uses a large amount of titanium alloy materials, many of which are welded casings with titanium alloy spoke structure. This type of titanium alloy spoke structure welding casing is usually welded by the inner casing, the outer casing and several spoke-shaped support plates. Welding stress generated during welding causes parts to deform, and heat treatment correction is required for the titanium alloy spoke structure welded casing. When using the heat treatment correction of the existing fixture, the inner case moves up due to the contraction of the support plate, causing the parts to be unqualified, and a second correction is required.
