本发明论及的是药筒,特别强调是以铝合金为材料制造的药筒.由于药筒的大量高速生产,这样,在药筒制造和严格检验过程中可能产生破裂以及其它不理想的特性.本文所涉及的破裂,包括小的裂纹故障.产生破裂的原因有二:1、制造过程中药筒壁发生破裂;2、可能是制造药筒材料固有的毛病而引起药筒壁部破裂.药筒的这种故障多半产生于退壳槽较前区域.由于从药筒壁部破裂处溢出高热气体,药筒就会受到严重烧蚀.这种破裂,特别对轻型铝药筒来说,有可能损坏炮栓、药室、运动部件的表面,致使火炮报废.更严
The present invention deals with cartridges, with a particular emphasis on cartridges made of aluminum alloy.As a result of the massively high-speed manufacture of cartridges, ruptures and other undesirable properties may occur during cartridge manufacturing and rigorous testing The ruptures involved in this article include small cracks that can cause rupture for two reasons: 1. Cracking of the cartridge wall during manufacturing; 2. Cracking of the cartridge wall may be caused by the inherent problems of manufacturing cartridge materials. This failure of the cartridge mostly results from the earlier area of the withdrawal channel, which can be severely ablated due to the high temperature of the gas spilled from the wall of the cartridge, especially for lightweight aluminum cartridges May damage the bolt, medicine room, moving parts of the surface, resulting in artillery scrapped.
