Abstract

The invention provides a warhead annular pilot chamber forming device and a forming method thereof, and belongs to the technical field of ammunition charging. The device used in the forming method comprises a die sleeve, a fixing sleeve, a pull rod, a core rod and a punch. Firstly, an annular cavity is formed between the inner wall of the die sleeve and the core rod at an opening of an ammunitionbody through cooperation of the die sleeve, the fixing sleeve, the pull rod and the core rod, then a certain amount of explosive is poured into the annular cavity, the fixing sleeve is taken out, thepunch is inserted into the annular cavity to compact the explosive, and therefore forming of an annular pilot chamber in the center of the end face of a warhead grain is achieved. According to the device and the method, the historical bottleneck that a cavity pilot chamber can only be formed in the center of the end face of the warhead grain through the step-by-step press-fitting charging and supplementary charging technology is solved. Through research and production practice verification, according to the warhead annular pilot chamber forming device and technology, the charging amount is increased, and then the damage effect of a warhead is improved.

Description

technical field [0001] The invention belongs to the technical field of ammunition charge, relates to step-by-step press-fit charge technology, and in particular to a warhead annular fuze chamber forming device and method thereof. Background technique [0002] As the defense ability of ammunition damage objects is getting stronger and stronger, the requirements for ammunition damage ability in modern warfare are also increasing. There are three key technologies to determine the damage capability of ammunition: the use of high-energy sources, advanced ammunition warhead structure design, and the use of advanced ammunition charging technology (including charging technology and equipment technology). Among them, ammunition charging technology is one of the core technologies of ammunition manufacturing and an important content of non-nuclear efficient damage. Therefore, the development of charge technology is not only an urgent need to improve the damage capability of ammunition...
