Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung von pressgehärteten Bauteilen, insbesondere Karosseriebauteilen von Kraftfahrzeugen, aus einer Platine aus ungehärtetem, warmumformbaren Stahlblech, wobei die Platine in einem Pressenwerkzeug zum Blechprofil warm umgeformt und gehärtet wird. Hierbei wird zunächst eine Platine gefertigt, deren Geometrie der Abwicklung des fertigen Bauteils entspricht. Anschließend wird diese Platine in einem Warmumform-Werkzeug zum Bauteil umgeformt und pressgehärtet, wonach das Bauteil mit einer Oberflächenbeschichtung versehen wird. Der gesamte randseitige Konturbeschnitt des Bauteils erfolgt vor dem Umform- und/oder Presshärtungsvorgang.The invention relates to a method for producing press-hardened components, in particular body parts of motor vehicles, from a blank of uncured, hot-formable steel sheet, wherein the board is hot formed and cured in a press tool for sheet metal profile. Here, a board is first manufactured, the geometry of which corresponds to the development of the finished component. Subsequently, this board is formed in a hot forming tool to the component and press-hardened, after which the component is provided with a surface coating. The entire edge contour cutting of the component takes place before the forming and / or press-hardening process.
