ABSTRACT:
A blind riveter has a pistol-shaped housing connected via hydraulic and pneumatic lines and a rivet-feed duct to an actuator and rivet-feed arrangement. The housing has a tip forming a mandrel-receiving aperture and formed of a plurality of inwardly biased but outwardly deflectable holding elements. A chuck is displaceable in this housing between a front position engageable around the mandrel extending back through the aperture from a blind rivet whose head rests against the tip and a back position spaced well back from this aperture. During displacement from the front to the back position the mandrel is pulled back to upset its rivet and is broken off and during displacement from the back to the front position, the chuck grips the mandrel of a blind rivet that was introduced from behind into the housing behind the aperture and pushes it through the aperture, deflecting the holding elements apart. The rivets are blown into the housing through the feed duct each time the chuck pulls all the way back, and the blast of air feeding the fresh rivet in blows the broken-off mandrel from the previous rivet out the housing. During upsetting of a rivet the holding elements forming the housing tip are locked together and prevented from spreading.
