Abstract

본 발명은 포탄 등에 사용되는 체결형 탄체 및 그 제조방법에 관한 것이다. 종래 이런 종류의 탄체는 모두가 일체형으로 되어 있기 때문에 가공이 어려워 탄체의 개발에 많은 시간과 비용이 소요되는 문제점이 있었으며, 특히 후단이 막힌 탄체의 경우에는 그 내부에 공동을 형성하는데 어려움이 있어 더욱 제조가 어렵게 되는 문제점이 있었다. 본 발명은 탄체를 전반부재와 후반부재로 분리 제작하여 나사식으로 체결함으로써 탄체의 제작 및 개발에 소요되는 시간을 단축시킬 수 있는 만큼 탄약 전체의 제조 및 개발에 소요되는 시간 및 비용을 절감할 수 있게 되는 것이다.The present invention relates to a fastening type body for use in shells and the like and a method of manufacturing the same. Conventionally, this type of carcass has a problem that it takes a lot of time and cost to develop the carcass because it is difficult to process because all of them are integrated, especially in the case of the carcass of the rear end is difficult to form a cavity therein There was a problem that manufacturing is difficult. The present invention can reduce the time and cost required for the manufacture and development of the whole ammunition as it can shorten the time required for the production and development of the carcass by screwing the carcass separately into the first half and the second half by making the screw. Will be.
