Gezielte Beeinflussung umformtechnisch induzierter Eigenspannungen beim Drahtziehen

Abstract: ZusammenfassungNach dem Drahtziehen treten hohe Zugeigenspannungen in den oberflächennahen Schichten des Drahtes auf. Dieser Eigenspannungszustand ist für die weitere umformtechnische Verarbeitung, z. B. für das Biegen zur Herstellung von Torsionstabfedern, ungeeignet. Nach derzeitigen Standards wird dem Drahtziehen eine Wärmebehandlung nachgeschaltet. In diesem Artikel wird ein neuer Ansatz zur Einstellung des Eigenspannungszustandes direkt im Umformprozess des Drahtes vorgestellt. Durch eine Modifikation der… Show more

“…The tool setup of the experimental device for the drawing process includes the interchangeable specific die with additional convex or concave geometric elements presented in the introduction, and for further details, it is referred to [ 5 , 16 , 17 , 18 ]. A solid lubricant (LOCTITE LB 8191) was applied to each of the samples, and additionally, lubrication with high-alloyed drawing oil was used during forming.…”

“…A solid lubricant (LOCTITE LB 8191) was applied to each of the samples, and additionally, lubrication with high-alloyed drawing oil was used during forming. For the current investigations, the drawing tools [ 5 , 18 ] were upgraded to include temperature measurements and were further adapted for drawing at higher speeds. In Figure 3 and Figure 4 , the drawing tool setups are presented.…”
