A bushing structure, a prefabricated fragment anti-personnel warhead and a manufacturing method thereof

Abstract

The invention discloses a bushing structure, a prefabricated fragment killing warhead and a manufacturing method thereof. The bushing structure includes several rounding units for placing prefabricated fragments. The rounding units include a diamond-shaped frame arranged axially and one end connected to the The bearing rib at the same top corner of the rhombus frame; the bearing rib is arranged on the radially inner side and the radially outer side of the bushing structure, and the other end of the bearing rib extends to the central area of ​​the rhombus frame, and The edge of the rhombus frame forms a bearing part that supports the prefabricated fragments; the adjacent rhombus frames are connected at the top corners to form an axial array of the rounded units in the axial direction, and form the circular unit in the circumferential direction. The circular array of the above-mentioned rounded units; the bushing structure of the present invention adopts the rounded units composed of multiple arrays of edges, and the prefabricated fragments can be fixed in the rounded units, so that the prefabricated fragments can be evenly distributed, and excessive constraints can be avoided on the basis of stable fixation The resulting trajectory deviation.

Description

technical field [0001] The invention relates to the technical field of manufacturing and assembling ammunition components, in particular to a bushing structure, a prefabricated fragment killing warhead and a manufacturing method thereof. Background technique [0002] Fragment kills the warhead mainly by the explosion of high-energy explosives to form a large number of high-speed fragments, and uses the high-speed impact, ignition and detonation of the fragments to damage the target. It can be used to kill living forces (people, animals), unarmored or lightly armored vehicles, aircraft, radar and missiles and other weapons and equipment. The prefabricated warhead is a kind of fragment killing warhead. The fragments are pre-processed and shaped, embedded in the shell matrix material or bonded to the inner lining outside the charge with resin, and the explosives explode to throw them out. The shape of the fragments is There are tile shapes, cubes, spheres, short rods, etc. Thi...

AI Technical Summary

Problems solved by technology

The titanium alloy thin-walled cylindrical framework in this scheme adopts the method of opening installation holes on the surface structure. On the one hand, its fixing effect on active fragments is poor, and the fixing positions are uneven; on the other hand, the cylindrical framework will be damaged during blasting. Generate additional fragments, absorb the energy of the ammunition to a certain extent, resulting in a reduction in energy utilization, and may also block the ballistic trajectory of active fragments, causing trajectory deviation
