ABSTRACT:
A blind rivet nut setting device includes a drawing mandrel, a motor, an interruptible first drive line for producing a rotational motion of the drawing mandrel, and a second drive line for producing an axial motion of the drawing mandrel. The second drive line includes a drive element and an output element. The drive element is axially movable and a portion of its axial movement length corresponds to an idle stroke with respect to the output element and a second portion of its axial movement corresponds to an effective stroke of the output element. The final point of the path of axial movement of the drive element is predetermined so that the effective stroke finishes immediately at the final point. The length of the idle stroke is adjustable.
