Method for molding shell matched with adaptor

Abstract

The invention discloses a method for molding a shell matched with an adaptor, and belongs to the technical field of solid rocket engine shells. The method comprises the following steps: 1, processinga shell body; 2, detecting the circle run-out of an area which is a position where the shell body is matched with the adaptor for to-be-wound fibers, and determining the circle run-out value and maximized circle run-out position of the cylindrical surface of the shell body in the area relative to the axes of the shell body; 3, winding glass fibers to the outer surface of the shell body matched with the adaptor to form a glass fiber layer; 4, curing the shell body wound with the glass fiber layer at medium and low temperature; and 5, processing the curing-molded glass fiber layer according to the circle run-out value and maximized circle run-out position in the third step to enable the circle run-out value in the area of the shell body wound with the glass fiber layer to be less than 1mm. The method can solve the problem that an existing thin-walled large-diameter high-strength steel metal shell is poor in matching with an adaptor of a cartridge.

Description

Technical field [0001] The invention belongs to the technical field of solid rocket motor casings, and in particular relates to a method for forming a metal casing matched with an adapter. Background technique [0002] The missile and the launch barrel adapter have geometrical matching problems. For missiles that use large-diameter high-strength steel thin-walled shell engines, heat treatment is required during the processing of the metal shell, and the heat treatment process will cause the thin-walled shell to become larger. Deformation. At present, during the assembly process, the adapter needs to be repaired according to the specific size of the single product before it can be installed with the engine. During the use and maintenance process, the adapter needs to mark the installation position; at the same time, the adapters are not interchangeable between each engine product of the same model This problem has aggravated the difficulty of the product in the final assembly of t...

AI Technical Summary

Problems solved by technology

[0003] In view of this, the present invention provides a method for forming a metal shell matched with an adapter, which solves the problem of poor matching between the existing thin-walled large-diameter (2m) high-strength steel metal shell and the adapter of the cartridge, By wrapping the glass fiber layer outside the matching area of ​​the shell body and the adapter, the adapters of the same type can be interchanged under the premise that the increase in structural mass is limited, reducing the assembly and use process of the metal shell and the adapter Moderate difficulty, greatly improving the performance of missile weapons
