Da das Blechprofil bei der im Zuge des Härtungsvorgangs vorgenommenen Kühlung im Pressenwerkzeug eingespannt ist, erhält man ein Produkt mit guter Maßhaltigkeit.From DE 24 52 486 A1 a process for the production of a cured one counts Sheet profile from a board in a Presshärtverfahren for State of the art, in which a made of hardenable steel board heated to hardening temperature, then hot worked in a press tool and then cured while the sheet metal profile in the press tool remains. As the sheet metal profile in the course of the curing process made cooling in the press tool is clamped receives a product with good dimensional stability.
Im Rahmen der WO 99/07492 ist vorgesehen, das vorbeschriebene Presshärtverfahren zu modifizieren und im Pressenwerkzeug die randseitigen Bereiche von vorgefertigten Löchern abzubiegen, so dass Kragen entstehen. In the context of WO 99/07492 is provided, the above-described Presshärtverfahren to modify and in the press tool, the marginal areas Turn off prefabricated holes so that collars emerge.
Dies geschieht im Pressenwerkzeug vor dem Härten. Die Öffnungen im Blechprofil sollen als Durchführungslöcher für Befestigungsschrauben dienen. Denkbar ist es, solche Löcher auch zur Lageorientierung des Blechprofils in nachfolgenden Fertigungsoperationen heranzuziehen.This happens in the press tool before hardening.

Auch ist die Maßgenauigkeit des hergestellten Blechprofils in die Abhängigkeit der Vorlochung gestellt. Werden die vorgegebenen Toleranzen verlassen, ist das Blechprofil unbrauchbar. Insbesondere bei Blechprofilen mit komlizierteren Geometrien muss mit größerem Ausschuss im Zuschnitt der Platinen kalkuliert werden.Unfavorable is the prefabrication of the holes in the output board. This is associated with additional manufacturing and logistics effort. Also is the Dimensional accuracy of the manufactured sheet profile in the dependence of the pre-perforation posed. If the given tolerances are left, that is Sheet metal profile unusable.
