Abstract

The rivet gun includes a change-over switching device (30) linked to controls (50,60) for reversing rotation of the motor (4). The controls (60) include an inlet valve (61) operated by a trigger for connecting compressed air infeed duct (14) in a feed-discharge duct (23) leading to the pneumatic cylinder (21). A discharge valve (63) is disposed in series with the inlet valve (6l) and has an adjustment ring for adjusting the maximum traction force. - The rivet gun includes a pneumatic motor (4), that drives a segment stem (7). A pneumatic cylinder (21) actuates a hydraulic cylinder (22) which sends oil under pressure to an expansion chamber (10) provided for moving back the segment stem (7) and buckling the rivet, fixing it to a laminate structure.
