Tungsten high density bucking bar rivet blocks
1)Tungsten bucking Details:
Tungsten bucking bar are placed behind work surfaces to provide a backing member in applying impact fasteners and including intermitted tool head and handle parts with a low-recoil impact-absorbing spacer provided there between to take shock loads in compression and shear.
2)Tungsten alloy bucking bar dimensions:
The size and weight of tungsten bucking bars depend on the size and alloy of the rivet to be driven. Under certain circumstances, and for specific rivet installations, specially designed bucking bars can be manufactured.
3)Tungsten alloy bucking bar applications:
Bucking bars are used on the backside of a metal rivet to counter the force of the hammering and to create bucktail. Bucking bar also can be used to absorb the force of rivet, reducing the vibration of bucking.
