Embodiment Construction
[0053] 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.
[0054] This embodiment proposes a method for preparing a titanium alloy variable-wall-thickness hollow active-cooling cabin. The variable-wall-thickness hollow active-cooling cabin is a 360° closed rotary body with a local reinforcement structure. The interior is a heading hollow structure. The wall thickness t1 is greater than the intermediate wall thickness t2, such as figure 1 shown.
[0055] The preparation method of the present embodiment specifically comprises the following steps:
[0056] The first step, tube blank preparation: divide the hollow active cooling cabin with variable wall thickness into 10 titanium alloy tube blanks for preparation. Such as figure 2As shown, the 10 tube blanks are the outer tube ...
