Abstract

The invention relates to a concentric launch canister body welding method in the field of welding deformation control. The concentric launch canister body welding method comprises the steps of: (S1) assembly of an inner cylinder and a shrinkage section; (S2) assembly of the inner cylinder and a guide rail base; (S3) correction of the deformation of the inner cylinder; (S4) welding of the inner cylinder and a reinforcing rib; (S5) assembly of an outer cylinder; (S6) installation of an outer hoop and a flange; (S7) overall welding molding; (S8) overall destressing of workpieces; and (S9) local shape correction of the workpieces. Multiple tools are matched for use in overall welding process of concentric launch canister bodies, so that the spot welding positioning can be performed to each part of the concentric launch canister bodies beforehand, the welding links in the process are reduced to the greatest extent, the technical effect of nearly once overall molding is achieved, and the concentric launch canister body welding deformation can be controlled with high precision; and the inner cylinder and the guide rail base need no machining after welding to greatly reduce the productioncost.

Description

technical field [0001] The invention relates to the field of welding deformation control, in particular to a method for welding concentric emitting cylinders. Background technique [0002] As a missile launcher, the concentric launcher is mainly used for missile transportation, storage and launch. The main structure of the concentric launching tube is the tube body, the guide rail, and the front and rear end covers. The concentric launching cylinder body is composed of an inner cylinder body, a contraction section, an outer cylinder body, a reinforcing rib, a guide rail seat, a flange, and an outer hoop. The inner cylinder is a cylinder; the shrinkage section is a cone; the outer cylinder is a plurality of circular arc plates; the ribs are grooved parts, wherein the ribs of the ribs are arc-shaped, and the outer diameter of the ribs is consistent with the outer diameter of the outer cylinder; The appearance of the rail seat is a trapezoidal groove; the outer hoop is a ring...
