Reduced Recoil Bucking Bar

The bucking bar includes a housing and a driven member movable with respect to the housing. The worker using the bar holds it with the driven member pressed against one end of the rivet. When blows are delivered from the hammer through the rivet to the bar, an appropriate reaction force is generated automatically by mechanisms within the bar. These mechanisms include at least a first pressure chamber and an exhaust port for releasing pressure from the pressure chamber to the atmosphere. By controlling the flow of air through the pressure chamber, the mechanisms within the bucking bar control the forces acting on the driven member during the recoil and rebound motions. Preferred control mechanisms include a second pressure chamber and a movable shuttle. The shuttle is initially biased in a preferred direction by a biasing element in the form of a coil spring. Subsequent movement of the shuttle is dependent upon the characteristics of the hammer blow. Generation of reaction force within the bucking bar is in turn dependent on the position and motion of the shuttle. Preferably, the shuttle acts as part of several valves controlling the flow of pressurized air into and out of the two pressure chambers. A piston fixed to the end of the driven member acts as part of another valve for controlling the flow of pressurized air into the first pressure chamber.

Specification of Tungsten Heavy Alloy Bucking Bar

Bucking bars made of tungsten alloy with high density are ideal for vibration-damping applications.

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.

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.

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

Tungsten Heavy Alloy bucking bars are resulting in a bucking bar of the same weight but half the size. Bucking bars are used in rivet setting to upset the shank of the rivet. Tungsten Heavy Alloy bucking bars reduce the recoil when reflecting the impact back to the rivet shaft.

Tungsten Bucking Bar Information

Tungsten bucking bars are absolutely one of the best investments you can make if you are building an airplane or do a lot of riveting. Tungsten bars are approximately twice the density of steel of the same size. This bars weighs 1lb 7oz.

This allows you to create a smaller bar that fits in more places, yet has the mass required to give excellent quality rivets. In addition, there is a lot less vibration than a comparable steel bar, which leads to reduced operator fatigue and less chance of injury.

Tungsten Steel Bucking Bar Description

Tungsten Steel bucking bars weighs almost twice as much as conventional steel which makes it a perfect material for manufacturing a small yet heavy bucking bar. As you know, the heavier the bar, the easier it is to shoot your rivet. With conventional steel bucking bars, installing rivets in open areas has never been a problem, but when the rivet is in a confined space and the ability to use a heavy enough bar to properly install the rivet without work hardening is not possible.

Why Choose Tungsten Heavy Alloy to Produce Bucking Bar?

Enjoy easier, better riveting with less fatigue. Tungsten heavy alloy bucking bars offer the maximum density available. These bars are more than twice as heavy as an identical bar made of steel. The small size and high density makes these bars versatile, able to fit in small areas. All bars have a full radius on all edges for safety and ease of handling.

Tungsten Heavy Alloy bucking bars are resulting in a bucking bar of the same weight but half the size. Bucking bars are used in rivet setting to upset the shank of the rivet. Tungsten Heavy Alloy bucking bars reduce the recoil when reflecting the impact back to the rivet shaft.

Higher density reduces vibration and kick back while bucking. Take a cue from the pros and use what they use. We carry a full line of standard bars and can custom build bars to your specifications. All bars have smooth faces and rounded edges and corners for ease and safety in handling.

According to the investigation for different bucking bars of the same shape but different materials and mass characteristics, use of heavier but same sized tungsten bucking bars can reduce vibration transmission to the hand.

In a word, tungsten bucking bars are very useful for bucking rivets and will make your life much easier in the build process.

Tungsten Heavy Alloy Bucking Bars

Tungsten heavy metal bucking bars are manufactured in sintered or polished alloys of 90%-95% tungsten with a nickel-copper-iron-moly matrix. These alloys are very similar to tungsten-carbides but the chemical composition is developed differently to reduce embrittlement. The high density (twice as heavy as steel) and tensile strength (110 kpsi) of this alloy makes the ideal combination for chatter free tools and supper chatter free tools. Heavy metal boring bars greatly enhance boring application by absorbing vibration and drastically reduce chatter, enabling to machine deeper bores with greater precision and finish.

Tungsten Heavy Alloy bucking bars are denser than steel, resulting in a bucking bar of the same weight but half the size. Bucking bars are used in rivet setting to upset the shank of the rivet. Tungsten Heavy Alloy bucking bars reduce the recoil when reflecting the impact back to the rivet shank.

High Density Tungsten Bucking Bars

High Density Tungsten Bucking Bars are 50% more dense than lead and over twice the density of steel. It presents an easy way to improve ergonomics in an aerospace manufacturing or other plant.

Tungsten Bucking Bar is used on the backside of a metal rivet to counter the hammering force. They also can be used to absorb the force of rivet guns, reducing the vibration of bucking.

Tungsten Bucking Bar has different shapes and dimensions, it depends on applicable circumstances.

Tungsten Bucking Bar Craft

Bucking bar is a piece of steel used to upset the driven head of the rivet. Bucking bars are made in a variety of sizes to fit various situations. Bucking bars must be handled carefully to prevent marring surfaces. When choosing a bucking bar to get into small places,choose one in which the center of gravity falls as near as possible over the rivet shank. Avoid using too light of a bucking bar,because this causes excessive deflection of the material being riveted. And in turn, it might cause marking of the outer skin by the rivet set. A bucking bar that is too heavy will cause a flattened driven head and might cause a loose manufactured head.

Back Riveting-Bucking Bar

Back riveting is a method of setting rivets, usually in a skin component, by striking the buck tails with a special gun set while the flush head is securely supported in its dimple or counter sink by a steel plate or bucking bar.

Control surfaces are usually back riveted using a horizontal steel plate mounted on a table. The skin rivets are held vertically in their holes with thin Scotch Magic tape or fine Mylar tapes over the heads. The internal rib or stiffener is placed over the rivets and the special gun set is used to sequentially set these fasteners.

Bucking bar orientation

1. Rest bucking bar on inserted rivet and try to locate its point of balance.
2. With gun set in place, use bucking bar to push rivet (and gun assembly) outward. Bucking bar will then register at right angles to the rivet as it comes to rest on the aluminum.
3. Push rivet back into place with gun set and reposition bucking bar, if necessary, to maintain its point of balance on the rivet. 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.
4. 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'
5. Duration of riveting is determined by experimentation with a test piece or previous experience.
