With the growing numbers of automobiles in Germany, the demands of modern passenger cars regarding safety and efficiency constantly increase. The application of hot stamped parts allows reducing the weight of the body in white and simultaneously improving passenger safety. However, high forming temperatures prevent the use of lubricants, so that high friction and tool wear limit the process window. In order to use the full potential of the hot stamping process, the development of measures to reduce friction and wear is needed. For this purpose, a method for characterizing the tribological conditions within hot stamping has been elaborated within this work. This method allows for analyzing the friction and wear conditions reproducible and specifically. With this method, a comprehensive process understanding regarding the predominant tribological conditions has been created. Based on the created process understanding tool-side measures for reducing friction and wear have been identified. The experimental investigations indicate that the choice, as well as the heat treatment of the tool material and the application of PVD-tool-coatings, can reduce friction and wear. Concluding, the transferability of the findings of the strip drawing tests on a B-pillar-geometry in laboratory-scale was shown. Thus, it can be concluded that the basic findings of this work can be used for hot stamping processes.<\/p>","protected":false},"excerpt":{"rendered":"
Mit steigenden Fahrzeugzahlen in Deutschland nehmen die Anforderungen an moderne Pkws hinsichtlich Sicherheit und Effizienz stetig zu.
