Nail Gun Working

Nail Guns or Power Nailers are great tool for building a two-story house, installing hardwood floors or running your own furniture repair shop, which is why you ought to know the nail gun basics before buying one. The simplest nail guns use ordinary springs to generate the hammering force. In these nailers, the motor (battery or electric powered) rotates two drive axles. The front axle moves a small scooper plate, a metal disc with a curved groove cut into it, and the rear axle moves a gear train, which turns a small triangular metal cam.

Nail-Loading Mechanism
The nails are glued together loosely, in a long strip. This nail strip loads into the gun's magazine, which feeds into the "barrel" of the gun. Springs in the base of the magazine push the nail strip into the barrel. When the hammer comes down, it separates the first nail from the strip, driving it out of the gun and into the wood. When the hammer is cocked back, the springs push the next nail into position.

An electromagnetic nail gun uses a solenoid as a hammer. When you pull the trigger:

1) The electrical circuit runs the current through the electromagnet so that the piston extends downward. Typically, the piston is attached to a sturdy blade.

2) The blade makes contact with the nail, forcing it out of the gun.

3) At the bottom of the cylinder, the piston hits an electrical switch.

4) Throwing this switch reverses the electrical current running through the electromagnet. The electromagnet draws the piston back in for another hit.
