Automatic blind rivet setting device

Abstract

A blind rivet setting device which automatically feeds blind rivets into a rivet table, then sets the rivet by pulling and detaching the mandrel. The rivet feed mechanism includes a thin strip or ribbon of flexible material capable of holding the mandrel tips pierced therethrough and evenly spaced apart. The strip is drawn through a transverse feed slot formed through the rivet table generally orthogonal to the longitudinal axis of the device. A spring biased retracting device continuously pulls the strip through the feed slot so that the next rivet in succession facing the rivet table is automatically drawn into axial alignment within the rivet table ready for positioning and setting into a work surface. A worm gear with eccentric output drives a connecting rod for pulling and fracturing each mandrel from the rivet body. A flywheel connected between a motor drive and the worm gear arrangement enhances mandrel pulling capacity.
