Nail Gun is a great tool for quickly and easily fastening two pieces of material together, and can make many tasks much easier and faster. They are powered either pneumatically or electrically and use a trigger to propel nails into a wide variety of materials. But how exactly do nail guns work?
The technology behind them is actually quite simple, and it has been steadily improved and modified over the years. In this article, we will take a look at what makes a nail gun work, and how it has become an invaluable tool for anyone who works with wood, plastic, and metal materials.
How do nail guns work?
A nail gun works through a very simple mechanism. When the trigger is pressed, a piston is driven forward. This action compresses a spring, which is released when the trigger is released. The force of the spring pushes a piston forward, driving a nail out of the gun and into the material being nailed. The piston is then reset, allowing the user to fire another nail.
The most common type of nail gun is a pneumatic nail guns and cordless nail guns.
Working Mechanism Of Pneumatic Nail Gun:
Pneumatic nail guns use compressed air to drive nails into a variety of materials with speed and accuracy. The pneumatic nail gun works by creating a high-pressure environment in the cylinder, which results in a pneumatic hammering action that propels the nail forward.
1. Compressed Air:
A pneumatic nail gun uses compressed air to power the nail driving mechanism. So air is compressed by a compresser and then stored in a chamber. This air is then released to power the nail driving action.
2. Triggering the Action:
The user pulls the trigger on the nail gun, which releases a small amount of compressed air. This air is then sent to the piston, which is the part of the gun that drives the nail.
3. Driving the Nail:
The air that is released from the trigger is sent to the piston, which drives the nail into the material. The piston is a cylinder that has a hole in the top and a hole in the side. The hole on the side is where the air enters. This pressure of air on the piston pushes the nail into the material.
4. Exhaust:
The exhaust of the pneumatic nail gun is the air that is released after the nail is driven into the material. The air is released from the piston and exits the nail gun.
Components of Pneumatic Nail Gun:
- Compressor: This is the main component of a pneumatic nail gun. It compresses air and provides a source of power for the nail gun.
- Air Hose: This is the part that connects the compressor to the nail gun and is necessary for powering the nail gun.
- Nail Magazine: The nail magazine holds the nails and feeds them into the gun when needed.
- Trigger: The trigger releases a burst of air which propels the nail out of the gun.
- Hammer: The hammer is responsible for striking the nail and driving it into the surface.
- Exhaust Valve: The exhaust valve releases the compressed air after the nail has been driven into the surface.
- Safety Mechanism: Most pneumatic nail guns come with a safety mechanism to prevent accidental firing.
Working Mechanism Of Cordless Nail Gun:
The cordless nail gun is a convenient tool for fastening materials. The working mechanism of the cordless nail gun is fairly simple and straightforward, making it easy to use and maintain.
1. Power Source:
The cordless nail gun is powered by a rechargeable battery. This battery sends an electric impulse to the motor, which in turn activates the piston to drive nails into the material.
2. Loading the Nail Gun:
Before using a cordless nail gun, it must be loaded with the appropriate size nails. This is typically done by inserting the nails into the magazine located at the bottom of the gun. The magazine is then locked into place, ensuring the nails are securely held in place.
3. Firing the Nail Gun:
To fire the nail gun, the user must press the trigger located at the top of the gun. This engages the motor, which then compresses the spring inside the gun. This results in the release of a piston, which propels the nail through the barrel and into the material that is being fastened.
4. Releasing the Nail Gun:
After the nail has been fired, the user must release the trigger of the nail gun. This disengages the motor and allows the spring to return to its original state, releasing the piston and allowing the nail to be ejected.
5. Reloading the Nail Gun:
Once the nail gun has been empty, the user must reload the gun with more nails. This is typically done by unlocking the magazine and inserting the nails into the chamber. The magazine is then locked back into place, ensuring the nails are securely held in place.
Components Of Cordless Nail Gun:
- Battery: The battery is the primary power source for the cordless nail gun. It is typically a rechargeable NiCad or lithium-ion battery.
- Trigger: This is the part of the nail gun that is used to fire nails. It is typically a pressure-sensitive switch that is activated when the user presses on it.
- Nose Piece: The nose piece is a metal piece located at the front of the nail gun that guides the nail into the surface being driven.
- Safety Switch: The safety switch is a lever designed to prevent accidental firing of the nail gun.
- Motor: The motor is responsible for driving the hammer that propels the nails out of the gun.
- Hammer: The hammer is what actually drives the nail out of the nail gun. It is typically made of steel and has a pointed tip that strikes the nail head.
- Barrel: The barrel is the part of the gun that houses the nails. It is typically made of steel or plastic and is designed to hold the nails securely in place.
- Magazine: The magazine is the part of the gun that holds the nails for easy loading and reloading. It is typically made of plastic or metal and can be loaded with either single or multiple nails.
