摘要 |
A rivet bucking tool (10) is provided with a damping piston (13) actuated by air pressure in a damping chamber (42) of the tool housing (11) of sufficient volume to isolate the housing (11) from undesirable vibration. The piston (13) forms an assembly with a bucking die (23) so as to inertially restrain recoil jointly therewith. A pressure reduction valve (28) is provided on the tool (10) for selectively setting the pressure in the damping chamber (42) to produce an elastic force bias on the assembly approximately equal to the optimal manual bucking force required for properly forming the rivet head and bucking in the riveting work at hand. |
