Rivet gun

technology Maturity 7-9 Next article →

A rivet gun is a special tool used to join metal pieces together.

It is often called a rivet hammer or a pneumatic hammer. Most of these tools use air to get their power. This air power helps the gun drive a rivet through two pieces of work. The rivet holds the parts tightly so they stay in place. These tools are very important for building big things like ships or planes.

To understand how it works, you can think of a piston inside the tool.

First, a worker squeezes a trigger on the handle. This opens a valve and lets pressurized air flow into the piston. The moving piston then strikes a part called a rivet set. This strike pushes the rivet into the metal work. On the other side, a bucking bar supports the tail of the rivet. The force flattens the tail into a new head called a shop head.

There are many different kinds of rivet guns for different jobs. Some guns are very large for working on heavy steel. Other guns are small enough to hold in just one hand for aircraft assembly. A slow-hitting gun strikes about 2,500 times every minute. This type is very common and easy to control. A fast-hitting gun can strike between 2,500 and 5,000 times per minute. These fast guns are sometimes called vibrators and work well with soft rivets.

Some tools work in even more unique ways. A corner riveter is a small tool made for tight spaces. It has a very short driver to work at right angles. A squeeze riveter uses air to squeeze the rivet from both sides at once. This tool creates very even results. There is also a special tool called a pop-rivet gun. This tool was invented by Hamilton Wylie in 1916.

A pop-rivet gun is different because it does not hammer the rivet.

Instead, it uses a metal shaft called a mandrel to form the rivet in place. When you squeeze the handle, a ball on the rivet tail pulls a metal sleeve tight. This creates a second head on the other side of the work. The metal sleeve is compressed between the ball and the original head. Finally, the mandrel reaches a weak point and breaks or "pops." This tool is handy because it does not need a bucking bar.
