High-safety nonmetal training cartridge and manufacturing method thereof

Abstract

The invention relates to a high-safety nonmetal training cartridge and a manufacturing method of the high-safety nonmetal training cartridge, aiming to realize the advantages of low cost and little environment pollution. The training cartridge comprises a cartridge bottom, an upper cartridge body, a cartridge top, a black powder column, a tracer mixture, a tracer pipe, a gunpowder transferring column and a gunpowder separating plate, wherein the cartridge bottom is made from a high-strength plastic nonmetal material; the upper cartridge body, the powder separating plate, the tracer pipe and the cartridge top are made from higher-brittleness nonmetal materials; threaded connection is adopted between the cartridge bottom and the powder separating plate, between the cartridge bottom and an upper cartridge body and between the upper cartridge body and the cartridge top; the black powder column is formed by stacking a plurality of round powder pieces with holes in centers and consistent size; the tracer mixture is pressed and arranged in the tracer pipe; and the tracer pipe is pressed and arranged in a cartridge bottom hole. The manufacturing method comprises the steps of: injecting sealant into a round groove of the cartridge bottom; inserting a steel bar in the cartridge bottom hole to close the cartridge case, wherein the closing-in pressure of the cartridge case is same as that of a typical cartridge; pulling out the steel bar in the cartridge bottom hole; pressing the tracer pipe loaded with the tracer mixture in and placing the black powder column in a cavity of the upper cartridge body; and placing the powder transferring column in the cavity between the powder separating plate and the black powder column.

Description

technical field [0001] The invention relates to the improvement of a non-damaging conventional training ammunition structure in the field of conventional ammunition structure design. Background technique [0002] Since World War II, the cost of all kinds of battlefield resources has risen steadily. If want to finish artillery shooting training task, reach required training effect, artillery and similar weapon systems just need to use a large amount of ammunition. Therefore, all countries are developing training bombs with reliable performance, high safety, low price and suitable for mass production. At present, the most widely used is the pyrotechnic release training device, which mainly simulates the battlefield scene effects after the artillery fires, such as flashes, explosions, and red smoke when hits. Because these training devices are required to be very safe, they must not cause harm to personnel, and daily logistics maintenance will not cause damage to personnel an...
