A riveting hammer, also known as a pneumatic hammer, but specifically it is a pneumatic riveting gun. It is a type of tool used to drive rivets. Nearly all rivet guns are pneumatically powered although some are just typical hand held hammers. (These more traditional hammers are available at Stiletto Tools.) The rivet gun is used on the manufactured head side of the rivet and a bucking bar is used on the buck-tail side of the rivet. Those rivet guns used to drive rivets in structural steel are quite large while those used in aircraft assembly are easily held in one hand. A rivet gun differs from an air hammer in the precision of the driving force.
Rivet guns vary in size and shape and have a variety of handles and grips. Pneumatic rivet guns typically have a regulator which adjusts the amount of air entering the tool. Regulated air entering passes through the throttle valve which is typically controlled by a trigger in the hand grip. When the trigger is squeezed, the throttle valve opens, allowing the pressurized air to flow into the piston. As the piston moves, a port opens allowing the air pressure to escape. The piston strikes against the rivet set. The force on the rivet set pushes the rivet into the work and against the buck. The buck deforms the tail of the rivet. The piston is returned to the original position by a spring or the shifting of a valve allowing air to drive the piston back to the starting position.
Riveting hammers and planishing hammers are the same in that they are both used with metal works, though there purposes are different. The role of a rivet tool when joining two pieces of metal together is to provide the force required to make the rivets go firmly into the holes made for them in manner that the rivets cannot come out again. Now doing this requires a considerable degree of force, as the holes drilled for the rivets are typically slightly smaller than the diameter of the rivets. This makes it impossible for the rivets to come out once they have been forced into the holes by the rivet tool. For this reason, in order to provide the amount of force required to push the rivets into the holes in a manner that makes it hard for the rivets to ever come out again, most rivet tools are available in the form of guns.
There are many available riveting hammers in the market, the HS recoiling riveting system. This product is designed to reduce vibration of the hands of the operator by approximately 85 percent. This reduces the health risk like carpal tunnel syndrome related to repetitive motion vibration. It eliminates the most harmful low-frequency and can be safely operated over the full workday, without sacrificing tool power, efficiency or reliability. This product features adjustable power throttle which allows usage in multiple rivet capacities and uses standard shack rivets. Orders can be processed online at hstooling.com.
