Applications of Tungsten Bucking Bar

Bucking bar is a work tool received behind work surfaces to provide a backing member in applying impact fasteners and including intermitted toolhead and handle parts with a low-recoil impact-absorbing spacer provided there between to take shock loads in compression and shear.

Tungsten bucking bars are used on the backside of a metal rivet to counter the force of the hammering on the other side. They also can be used to absorb the force of rivet guns, reducing the vibration of bucking.

Tungsten bucking bars used to form bucktails on rivets. And come in many different shapes and sizes. They are normally made from an alloy steel similar to tool steel. The particular shape to be used depends upon the location and accessibility of the rivet to be driven.

The size and weight of the bar depend on the size and alloy of the rivet to be driven. Under certain circumstances, and for specific rivet installations, specially designed bucking bars are manufactured locally.

At Chinatungsten Online,  tungsten bucking bars are normally made from tungsten heavy alloy. All edges are deburred and working surfaces are polished for troubles-free use. This helps to prevent marring of formed bucktails. Please notice that never hold a bucking bar in a vise unless the vise jaws are equipped with protective covers to prevent marring of the bucking bar.

Working Principle of Tungsten Bucking Bar

The tungsten bucking bar may be secured in a bench vice and, with the components positioned by hand; rivets are set with a gun held in the other hand.  The main advantage here is that the bar is stationary and the components may be more easily held and positioned for riveting.

Tungsten Bucking bar orientation

Rest tungsten bucking bar on inserted rivet and try to locate its point of balance.

With gun set in place, use tungsten bucking bar to push rivet (and gun assembly) outward. Tungsten bucking bar will then register at right angles to the rivet as it comes to rest on the aluminum.

Push rivet back into place with gun set and reposition bucking bar, if necessary, to maintain its point of balance on the rivet. (repeat steps 2and 3until point of balance is determined). Often the index finger can be placed on the back of the bucking bar directly opposite the rivet tail. It then becomes the ‘sensor’ for correct bar position.

Pressure is held on gun while riveting. Bucking bar is held with only moderate force (otherwise rivet may be set with head proud of surface). A rubber grommet may be used over the rivet tail to assist in squeezing parts together during riveting. It acts as a 'pressure plate' .

Duration of riveting is determined by experimentation with a test piece or previous.
