ABSTRACT:
A rivet bucking tool (10) is provided with a damping piston (13) having a skirt (18) thereon and in which the shank (25) of a rivet bucking die (23) is freely removably received. This allows easy exchange of the dies (23) for piston recoil adaptation to rivets of different size and material. The area transformation between the shank (25) and the damping piston (13), the skirt (18) thereon, and the preferably airtight frictional fit of the skirt (18) around the shank (25) are utilized to convert bucking stress into vibration so as to reduce joint recoil of the damping piston (13) and die (23) during bucking. Vibration and recoil are absorbed in the tool housing (11) by compressed air in a damping chamber (42) wherein the pressure is selectively adjustable by a valve (28).
