Embodiment Construction

[0037] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] This example proposes a method for preparing a titanium alloy thin-walled lightweight flap. The shape of the prepared flap is as follows figure 1 As shown, it has a surrounding mounting surface 1 , a middle diffusion welding area 2 and a rib area 3 . Wherein, the thickness t1 of the surrounding mounting surface 1 is 4 mm, the thickness t2 of the middle diffusion welding area 2 is 2 mm, and the thickness t3 of the rib area 3 is 0.5 mm.

[0039] The preparation method of the titanium alloy thin-walled lightweight cover specifically includes the following steps:

[0040] S1. Mold design

[0041] According to the final theoretical shape of the part, the flat diffusion welding mold and the hot pressing superplastic ...

Abstract

The invention provides a preparation method of a titanium alloy thin-wall lightweight covering cap part. According to the method, a titanium alloy diffusion connection and superplastic forming processmethod is adopted, flat plate diffusion welding is firstly adopted, and then hot pressing superplastic forming is carried out, so that full diffusion connection of two layers of plates in a diffusionwelding area can be ensured. According to the method, gas is adopted for diffusion welding, so that the diffusion welding rate of 100% of formed parts can be ensured; during the flat plate diffusionwelding, sealing is carried out in a mode that a sealing groove is formed in a die, so that smooth air paths of hot-pressing superplastic forming can be guaranteed; the periphery of the prepared titanium alloy lightweight structure covering cap is preset in the form of a reinforcing frame, so that unequal thicknesses of an installation surface and a middle part can be realized, the strength and rigidity of the part are guaranteed, and weight reduction is facilitated; the diffusion welding rate of the covering cap is high, the requirement of light weight and high strength can be met, the integrity of the part is good, subsequent shape correction is avoided, and the forming precision is high.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy processing, and in particular relates to a method for preparing titanium alloy thin-walled lightweight mouth cover parts. Background technique [0002] Lightweight, high-strength thin-walled components are more and more widely used in projectile structures. In order to meet higher performance requirements and achieve substantial weight reduction, the composite integral forming technology of titanium alloy superplastic forming and diffusion bonding has become the main solution for manufacturing thin-walled hollow components. The cover is mainly used as a window for installation and testing. The cover destroys the integrity of the projectile structure from the perspective of the projectile structure, but it is an indispensable part of the projectile structure from the perspective of function. In order to maintain the overall structural strength and rigidity of the projectile structure, the a...
