A fixed propulsion system for molded shell gunpowder, its fasteners and processing technology

Abstract

The invention discloses a plastic shell gunpowder fixing propelling system and a fastener and a machining process thereof and belongs to the field of fastener fastening instruments. The system comprises a gunpowder charging bin. A gun propellant hole is formed in one end of the gunpowder charging bin, the other end of the gunpowder charging bin is a primer end, and a powder load gun propellant is arranged in the gun propellant hole. A primer mixture hole is formed in the bottom of the gun propellant hole and a powder load primer mixture is arranged in the primer mixture hole. An anti-explosion gap is reserved between the powder load gun propellant and the powder load primer mixture. A stepped hole is formed by the gun propellant hole and the primer mixture hole and the gun propellant hole is larger than the primer mixture hole. Quality accidents caused by the reduction of the firing rate of a shell-free powder load due to the fact that the shell-free powder load is exposed outside and absorbs moisture are effectively avoided, safety accidents of explosion, caused by various factors such as collision, high temperature and open fire, of the shell-free powder load can be avoided as well, and meanwhile through the arrangement of the gun propellant and the primer mixture, it can be guaranteed that the powder load is effectively triggered, and the high firing rate is guaranteed.

Description

technical field [0001] The invention relates to the field of nail-shooting and fastening equipment, in particular to a molded case gunpowder fixing propulsion system, fasteners and processing technology thereof. Background technique [0002] In the use of the current nail shooter, most of the nail fasteners used are the structure with the exposed nail bullets without shells. The patent number is ZL201020539750.3, which discloses a fastener with this structure. In actual use, it was found that the nail-shooting bullet without a case was exposed to the influence of air humidity and easily absorbed moisture, which caused the problem of a low fire rate of the nail-shooting bullet, high safety hazards, and low production efficiency. In addition, there is also the problem that due to the exposed nail-shooting bullet without the case, the tip of the nail and the nail-shooting bullet without the case are likely to collide during transportation, which may cause an explosion and cause...
