摘要： In an automatic screwer a tubular housing (1) features a channel (4) provided with pliers (8) for keeping a screw (7) inserted in the channel while a shell (9) contains a pneumatic motor for rotating a blade (10) that can be inserted in the head (7b) of the screw (7) with a pneumatic distributor connected with two chambers (12, 13) and a lever (20) linked to the distributor (35) to set under pressure either the return chamber (12) or the final advancement chamber (13). An initial advancement chamber (15a) is connected with a source (100) of compressed air through an intake valve (30) and a piston (14) slides in the chamber (15a). The intake valve is controlled so as to set under pressure the initial advancement chamber (15a) with advancement of the piston (14) and engagement of the blade (10) with the head (7b) of the screw (7), or with discharge of the initial advancement chamber (15a), according to the release or the operation of the lever (20).

摘要： A 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 (2) fixing it to a laminate structure (100). The rivet gun also 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 (64) for connecting a compressed air infeed duct 14 with a feed-discharge duct (23) leading to the pneumatic cylinder (21). A discharge valve (63) is disposed in series with the inlet valve (61) and has an adjustment ring (176) for adjusting of the maximum traction force. Another discharge valve (90) is disposed in series with the discharge valve (63) previously mentioned and is provided for adjustment of the stroke of the segment stem (7).

摘要： 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.
