Die vorbekannte Vorrichtung verfügt über eine eine Setzsteuernut aufweisende Setzsteuerkulisse und über einen Nietstößel, der mit einem Setzsteuerstift in Verbindung ist, der wiederum in die Setzsteuernut eingreift. Weiterhin ist eine Vorlageschaftstange vorhanden, an der die Setzsteuerkulisse drehfest angebracht ist. Die Vorrichtung ist überdies mit einer Antriebseinheit ausgestattet, mit der die Vorlageschaftstange zu einer Drehung antreibbar ist, um den Nietstößel zwischen einer rückgezogenen Vormontagestellung und einer vorgeschobenen Montagestellung zu bewegen. Dadurch lässt sich ein insbesondere als Spreizniet ausgebildetes Befestigungselement mechanisch setzen, indem über die Bewegung des Nietstößels beispielsweise ein Nietstift zwischen Federarme eines Spreiznietes einschiebbar ist. Bei dieser Vorrichtung steht ein mit der Vorschubstange in Verbindung stehender Niethaltekopf relativ wenig über eine Stirnseite eines Aufnahmegehäuses über, was eine insgesamt kompakte Bauform ergibt.Such a device is off DE 10 2005 054 719 B3 known. The prior art device has a set control cam having a set control groove and a rivet ram in communication with a set control pin which in turn engages the set control groove. Furthermore, a Vorstelleschaftstange is present, on which the Setzsteuerkulisse is mounted rotatably. The apparatus is further provided with a drive unit with which the master rod is rotatable to move the rivet follower between a retracted pre-assembly position and an advanced assembly position. As a result, a fastening element designed in particular as a spreader rivet can be mechanically set in that, for example, a rivet pin can be inserted between spring arms of a spreader rivet via the movement of the rivet ram. In this device, a rivet holding head communicating with the feed rod projects relatively little beyond an end face of a receptacle housing, resulting in an overall compact design.
