Nail gun, also known as nail shooter, is often called nail gun because of its similar appearance and principle to pistol. It is a tool for driving nails into buildings by using gunpowder gas produced by blank ammunition as power. Empty shells, who fired the nails, are just different in size from ordinary military empty shells, and are also harmful to people.
Nail gun is an advanced modern fastening technology, which has many advantages compared with traditional methods such as embedded fixation, drilling and grouting, bolt connection and welding. It has its own energy, thus getting rid of the burden of wires and air ducts, which is convenient for on-site and aerial work. The operation speed is fast and the construction period is short, which can greatly reduce the labor intensity of workers; The function is reliable and safe, and it can even solve some construction problems in the past; Save money and reduce construction cost.
According to the action principle, nail gun can be divided into two categories: direct action nail gun and indirect action nail gun.
Direct-acting nail gun:
Direct-acting nail shooter uses gunpowder gas to directly act on dry nails to promote nail shooting. Therefore, when the nail gun flies away from the nail tube, the speed (about 500 m/s) and kinetic energy are very high.
Indirect action nail gun:
The gunpowder gas indirectly acting on the nail shooter does not directly act on the nail shooter, but acts on the piston in the nail shooter, and the energy is transferred to the nail shooter through the piston. Therefore, the nail leaves the nail tube at a lower speed. There is a great difference in the nail shooting speed between the direct nail shooter and the indirect nail shooter.
At present, except for special circumstances, others generally do not use direct nail guns, but use indirect nail guns. Reliability and safety are far superior to the former. In terms of use, some nail guns are only suitable for repairing ingot molds, fixing insulation boards and hanging signs in metallurgical industry, so they are named special nail guns, while others are suitable for all walks of life, so they are also called general nail guns.
