Fuel press-fitting mold for cylinder thin-wall structure projectile body and using method of fuel press-fitting mold

Abstract

The invention belongs to the technical field of weapons and ammunition, and relates to a fuel press-fitting mold for a cylinder thin-wall structure projectile body and a using method of the fuel press-fitting mold. The fuel press-fitting mold comprises a base, an ejector head, a first sleeve, a fastening structure and a pressing rod; a first groove is formed in the top face of the base, and the section of the first groove is circular; the ejector head is coaxially arranged in the first groove in a sleeved manner and is used for limiting the projectile body; the first sleeve is coaxially arranged in the first groove in a sleeved manner and located on the upper side of the ejector head; the fastening structure is arranged on the base and used for fixing the relative positions of the first sleeve and the first groove; and the pressing rod is inserted in the first sleeve. The fuel press-fitting mold is low in manufacturing cost, the manufacturing cost is reduced, the press-fitted shape has good repeatability, then the influence on the aerodynamic characteristic consistency of an outer trajectory is reduced, due to the protection design for the thin-wall part of the projectile body, the thin-wall projectile body can be protected in the press-fitting process, deformation is avoided, it can be guaranteed that high-temperature is not in direct contact with personnel in the whole process, the risk that the personnel are scalded is reduced, the structural adaptability is high, flexibility is achieved, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of weapons and ammunition, and in particular relates to a fuel press-fitting die for cylindrical thin-walled projectiles and a method for using the same. Background technique [0002] Hollow ammunition is a kind of high-speed and low-resistance ammunition, which occupies an important position in the development of ammunition. The cylindrical structure of the ammunition is the most prominent feature of hollow ammunition, but it is precisely because of this internal structure that the charge and launch of hollow ammunition are subject to This restricts and limits the development of hollow bullets. [0003] The problem with the current existing technology is that in order to reduce the weight of the bomb and reduce the flight resistance, most of the hollow bullets can only adopt a thin-walled structure, and then only with the help of the bullet holder and the conventional shell charging can the launch condition...

AI Technical Summary

Problems solved by technology

[0005] At present, the design of the injection mold for this type of ammunition is still blank, and due to research needs, the inner surface of the fuel needs to be adjusted frequently, which also brings difficulties to the design of the injection molding mold
