Embodiment 1

[0026] This fragment module is a schematic diagram of the modular structure of a large warhead cavity head fragment ( figure 1 ). In order to make full use of the inner cavity space of the warhead head and ensure the quality and center of mass of the warhead, the fragmentation module of this structure is designed. The specific process method is as follows:

[0027] First, determine the shape and size of the module according to the technical parameters of the warhead, design and process the mold. Clean the fragments with gasoline and alcohol, weigh the spherical fragments and put them into the mold according to the requirements of the drawing, vibrate or shake to make them densely arranged, slowly inject the vacuumed adhesive into the mold, let the adhesive fill every gap in the fragments, and then seal the mold, according to the process Heating and curing at the required temperature. After curing, disassemble the mold, clean and weigh the module, and apply adhesive evenly o...

Embodiment 2

[0029] This fragment module is a schematic diagram of the modular structure of the cylindrical part of a small warhead ( figure 2 ), if the size of the mouth of the warhead is smaller than the size of the inner cavity, the overall design fragment module cannot be assembled. After the fragment module is divided into three equal parts (divided along the circumferential direction), they are respectively pasted on the inner wall of the warhead shell. The specific process method is:

[0030] According to the design requirements, the fragments are initially divided into three equal parts. After the equal parts, the size of each fragment is just smaller than the size of the mouth of the warhead, which can realize smooth assembly. First, design and manufacture the mold according to the size and shape of each piece, weigh the spherical fragments into the mold, vibrate or shake to make the distribution dense; place the mold vertically on the platform, slowly inject the vacuumed adhesiv...

Abstract

The invention discloses a modular assembling method for a prefabricated spherical fragment of an ammunition warhead. The method comprises the following steps that modularization of the prefabricated spherical fragment is conducted, specifically, according to the technical requirements for the size, quantity, dimension, quality and center of mass of the fragment, the structural requirements of an inner cavity of a warhead are met, the shape and dimension of the fragment are designed, and the fragment is vertically and horizontally divided into a plurality of small pieces, a mold is designed according to the shape and dimension of each piece; according to the design weight of each piece of fragment, the pieces of fragments are weighed and put into the mold by adopting a regular arrangement method or a vibration method as the putting method; and after the pieces of fragments are put into the mold, an adhesive is poured into the mold, gaps among the fragments are filled with the adhesive,and a module with a required shape is formed after curing, so that the fragments and the mold are modularized into a whole. Compared with the prior art, module dividing can be performed according to the shape of an inner cavity of the warhead, the fragment modules with the needed shapes are obtained through the mold, the fragment modules are bonded to the corresponding positions of the inner cavity of the warhead, and the assembling requirements of fragments of various warheads are met.

Description

technical field [0001] The invention relates to the technical field of assembly of ammunition components, in particular to a modular assembly method for prefabricating spherical fragments of ammunition warheads. Background technique [0002] In order to improve the lethal power of weapons and ammunition, designers achieve the goal by increasing the amount of charge, increasing the explosive density and range, etc., without changing the shape and launch platform, by changing the internal structure, that is, by loading prefabricated spherical fragments. for this purpose. At present, the commonly used prefabricated spherical fragment methods include mechanical processing method and integral mold compression molding method. [0003] The mechanical processing method is to engrave prefabricated grooves on the inner cavity or outer surface of the warhead, and when the warhead explodes, it will be broken according to the prefabricated grooves to form fragments to improve the killin...
