Abstract

A setting apparatus in which a mandrel of a blind rivet is inserted into a hole of a nose at the front end of the setting apparatus, and wherein a rivet body of the rivet is projected from the nose into a mounting hole of a workpiece. The mandrel is pulled rearward of the nose with a force capable of breaking the mandrel and expanding a shank of the rivet body so that the rivet is set in the workpiece by the expanded shank and a flange of the rivet body, followed by discharging of the broken mandrel from the setting apparatus. The force for pulling the mandrel is obtained from hydraulic pressure of a hydraulic cylinder . The hydraulic pressure is produced by a piston which moves in a pneumatic cylinder adjacent to the hydraulic cylinder. The nose is axially aligned with an apparatus body including the hydraulic cylinder and the pneumatic cylinder along the longitudinal direction of the setting apparatus from the front end to the rear end thereof. A discharge path for the broken mandrel is formed by a hollow tube extending from the mandrel inserting hole of the nose through (tubes and of) the apparatus body and (a tube of) the hydraulic cylinder to the rear end of the setting apparatus.
