Abstract

Zur Herstellung eines Bolzenelements mit einem Schaft, der im Bereich seines freien Endes einen verringerten Durchmesser aufweist, wird vorgeschlagen, ausgehend von einem zylindrischen Drahtstift die Reduzierung des vorderen Abschnitts durch einen Walzvorgang herzustellen. Bei einem Bolzenelement mit Gewinde, also beispielsweise einer Schraube, kann das Reduzieren des Durchmessers und das Aufwalzen des Gewindes in einem Vorgang mit Hilfe eines einzigen Walzbackenpaares erfolgen. Das Walzbackenpaar enthält eine Reduzierfläche, mit deren Hilfe die Durchmesserverringerung durchgeführt werden kann.
