A pneumatic riveter uses air pressure to drive a rivet into metal. There are three types: riveting machines, rivet guns, and automated assembly line riveters. The rivet is inserted into a hole and a buck is used to push against it. The riveting process is quick and involves air pressure pushing a piston down to flatten the back of the rivet. There are three methods of driving rivets: single-shot, slow-blow, and fast-blow, with the slow-blow being the most common.
A pneumatic riveter is a tool that uses air to create enough pressure to drive a rivet into structural metal. There are three basic configurations for a pneumatic riveter; riveting machines, riveting machines and riveting machines. Each of these work similarly, but have a slightly different construction. These three types have different methods of actually driving the rivet. These riveters are common in many types of manufacturing and construction, from building skyscrapers and airplanes to reinforcing blue jeans.
Most rivet guns, regardless of size and configuration, work the same way. The rivet is inserted into a hole in the metal; this hole is often slightly smaller than the rivet to facilitate a strong connection. A solid metal block, called a buck, is placed on the opposite side of the pneumatic riveter to provide a surface to push the rivet against.
The actual rivet pounding process is made up of many steps, but happens in a fraction of a second. The air is pumped into a containment chamber inside the riveter where it is held under pressure. When the riveter pulls the trigger, air rushes into a piston chamber and pushes the piston down. This pushes the rivet down into the buck, flattening the back of the rivet.
The construction of the pneumatic riveter has less to do with how it works and more to do with how it is used. A rivet tool is a large machine that is generally used in the construction of a building or large machinery. Rivet guns are smaller handheld tools used for lighter projects, such as aircraft construction. Both of these tools are held directly by an operator who has full control over them. Riveters are part of a larger manufacturing process and are often found on automated assembly lines.
Three main methods can drive rivets into metal. The single-shot riveter drives the rivet down with one extremely powerful blow. These riveters are used almost exclusively on high-strength metals, such as steel. If used on a lighter metal, the impact would deform the impact point structure. While this method is usually very fast, it also requires a highly skilled operator.
The other two types of pneumatic riveters repeatedly strike the rivet as long as the operator continues to hold the trigger. This incrementally drives the rivet into the metal and deforms the back. In general, these riveters are easier to use than the single shot type. A slow-blow pneumatic riveter strikes the rivet between 1,500 and 2,500 times per minute, while a fast-blow riveter can strike up to 5,000 times per minute. The slow impact riveter is the most common style of riveter on the market.
