What types of nail shooters are there and what are the principles?

The principle of the nail gun is to use the gunpowder gas generated by hitting the nail shell to push the piston rod, and then push the nail forward to achieve the purpose of fastening or connecting.

When in use, first put the nail in the barrel with the push rod, then put the nail bullet into the bullet cavity, then aim the gun at the fastening part, compress the barrel with considerable force, and then pull the trigger , So that the firing pin hits the bottom of the nail bullet and the gunpowder of the nail bullet explodes, so that the nail produces a high-pressure thrust.

An ordinary nail shooter has a plastic bracket in the middle of the nail, which is used to fix the nail in the barrel. The shell is about 4-5mm in diameter, and the mouth is tight, like an empty shell. When using, press the muzzle on the nail position and pull the trigger. The sound is deafening, similar to the sound of a normal rifle. The propellant is very powerful. If the nail is located in a normal brick wall instead of a concrete wall, the nail will always penetrate the wall.

According to the principle of action, nail guns can be divided into direct action nail guns and indirect action nail guns.

Direct nail shooter:

The direct nail - shooting device uses gunpowder gas to directly act on the dry nail - shooting device to push its movement. In this way, the nail has a high speed (about 500 m/s) and kinetic energy, and it can fly out of the nail tube.

Indirect action nail shooter:

The gunpowder gas in the nail shooter does not directly act on the nail shooter, but on the piston in the nail shooter, and the energy is transferred to the nail shooter through the piston. Therefore, the speed of the nail shooting machine is slow when it leaves the nail tube. There is a big difference in the speed of the direct-acting nail shooter and the indirect nail shooter.

What is the working principle of an electric nail gun?

There is an acceleration coil in the shell of the electric nail gun. The acceleration coil is equipped with a hammer body track. The hammer body can move in the hammer body track. The hammer body is made of magnetic conductive material. The front end of the hammer body is equipped with a striker. The control switch controls the electric nail Gun work. The punch body is provided with at least two rollers, the outer contour of the roller is higher than the outer surface of the punch, and the roller can rotate around its pin shaft. When the outer edge of the roller is in contact with the hammer path outside the hammer body, the friction arm of the hammer path and the roller is significantly larger than the force arm of the roller pin, so that the roller can rotate flexibly around its pin, thereby reducing the hammer in the movement process. Friction reduces the heating of the electric nail gun and prolongs the service life of the nail gun.
