A kind of molding method of the shell matched with the adapter

Abstract

The invention discloses a molding method of a housing matched with an adapter, which belongs to the technical field of solid rocket motor housings. The steps are as follows: the first step is to process the housing body; the second step is to cooperate the housing body with the adapter The position is the area where the fiber is to be wound, and the circular runout in this area is detected, and the circular runout value and the maximum circular runout position of the cylindrical surface of the shell body in this area relative to its axis are determined; the third step is to match with the adapter. The outer surface of the shell body is wound with glass fiber to form a glass fiber layer; the fourth step is to cure the shell body wrapped with the glass fiber layer at a medium and low temperature; the fifth step is to Position, process the cured and formed glass fiber layer, so that the circular runout value in the area where the shell body is wrapped with the glass fiber layer is less than 1mm; The problem of poor adapter matching.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motor casings, and in particular relates to a molding method for a casing matched with an adapter. Background technique [0002] There is a problem of matching the geometric dimensions of the missile and the launch tube adapter. For missiles using a thin-walled shell engine made of large-diameter high-strength steel, heat treatment is required during the processing of the metal shell, and the heat treatment process will lead to a larger thickness of the thin-walled shell. Deformation. At present, during the assembly process, the adapter needs to be repaired according to the specific size of a 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 between the same model engine products are not interchangeable. This problem has exacerbated the difficulty of the product...

Problems solved by technology

[0003] In view of this, the present invention provides a method for forming a housing matched with an adapter, which solves the problem of poor matching between the existing thin-walled large-diameter (2m) high-strength steel metal housing and the adapter of the cartridge. The glass fiber layer is wrapped around the area where the shell body matches the adapter, and on the premise that the increase in structural mass is limited, adapters of the same type can be interchanged, reducing the time spent on assembling and using the metal shell and the adapter. difficulty, greatly improving the performance of missile weapons
