Embodiment

[0043] like figure 1 As shown, the launch tube includes barrel section I to barrel section VII, and barrel section I to barrel section VII are sequentially formed into a whole through welding and tooling. In the present invention, the inner diameter of the launch barrel is 1984 mm, the thickness of the tank wall is 6 mm, and the total length is 9380 mm. A specific preparation method thereof is described.

[0044] Step 1 picking: Picking Q345, δ6 board, check the material quality certificate and the mark on the material according to the standard GB / T3274-2007, and the surface of the material should not have scars, cracks, folds, inclusions, air bubbles, and iron oxide sheet pressing, which are harmful to use defects, the steel plate shall not have delamination. The surface defects of the steel plate are allowed to be cleaned, and the cleaning should be smooth without edges and corners, and the allowable minimum thickness of the steel plate should be guaranteed.

Abstract

The invention relates to a method for preparing a launching tube suitable for missile launching, which comprises the following steps: picking-marking-cutting-cutting-edge planing-drum-cleaning-pairing-welding-campus-nondestructive testing-grinding- Heat treatment—Cleaning—Assembly—Machining—Scribing—Drilling—Inspection and warehousing. Through the preparation method of the present invention, the high-precision requirements of mechanical processing are guaranteed; the high-precision shape and position tolerance assembly requirements of the manufacturing tooling support are guaranteed; the alignment misalignment amount, edge angle and weld reinforcement during welding are guaranteed; Accurate size requirements; the launch tube has storage space, maintenance space and launch system at the same time.

Description

technical field [0001] The invention relates to a method for preparing a launching device, in particular to a method for preparing a launching tube suitable for missile launching. Background technique [0002] At present, the technical problem that the launch tube technology field has always wanted to solve is to enable the equipment of the launch tube to provide a storage space, a maintenance space, and a launch system. However, the main technical problems in the existing technology are as follows: [0003] (1) Machining guarantees the high-precision dimensions required by the drawings. [0004] (2) Make tooling supports to ensure the assembly of high-precision shape and position tolerances required by drawings. [0005] (3) When welding, ensure the amount of misalignment, edge angle and weld reinforcement. [0006] (4) When opening holes, ensure the high-precision dimensions required by the drawings. Contents of the invention [0007] Aiming at the problems in the abo...
