Der Erfindung liegt die Aufgabe zugrunde eine gegenüber dem Stand der Technik verbesserte Vorrichtung zum Warmumformen von Metallblechen anzugeben.Of the Invention is based on the object one over the State of the art to provide improved device for hot forming metal sheets.
Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The The object is achieved by the in the claim 1 specified characteristics solved. Advantageous developments The invention are the subject of the dependent claims.
Die erfindungsgemäße Vorrichtung zum Warmumformen eines Werkstückes, insbesondere von Metallblech, umfasst mindestens zwei Werkzeughälften, die jeweils an einer Aufspannplatte befestigbar sind. Erfindungsgemäß weist wenigstens eine Werkzeughälfte Bereiche mit unterschiedlichen Wärmeleiteigenschaften auf.The Hot-forming device according to the invention a workpiece, in particular of sheet metal, comprises at least two mold halves, each on a platen are fastened. According to the invention, at least one Tool half areas with different heat conduction properties on.
Anhand der Bereiche mit unterschiedlichen Wärmeleiteigenschaften ist es in Gewinn bringender Weise möglich, eine lokale Abkühlgeschwindigkeit des Werkstückes gezielt zu beeinflussen. Das bedeutet, dass durch die verschiedenen Wärmeleiteigenschaften der Bereiche ein Abkühlverhalten in ausgewählten Abschnitten des Werkstückes verzögert oder beschleunigt werden kann. Durch die aus den verschiedenen Wärmeleiteigenschaften resultierenden lokalen Abkühlgeschwindigkeiten ist es in vorteilhafter Weise realisierbar, dass vorgegebene Abschnitte des Werkstückes beispielsweise eine geringere Festigkeit und/oder eine höhere Duktilität im Vergleich zu weiteren Abschnitten des Werkstückes aufweisen.Based the areas with different heat conduction properties is it possible in a profitable way, a local Cooling speed of the workpiece targeted to influence. That means that through the different heat conduction properties the areas have a cooling behavior in selected Delayed or accelerated sections of the workpiece can be. Due to the different heat conduction properties resulting local cooling rates, it is more advantageous Realizable manner that given sections of the workpiece For example, a lower strength and / or a higher Have ductility compared to other sections of the workpiece.
Zusätzlich zu der lokalen Gestaltung der Wärmeleiteigenschaften der Werkzeughälfte kann die Werkzeughälfte lokale Temperierelemente aufweisen. Mit Hilfe dieser zusätzlichen Temperierelemente kann die (lokale) Temperatur der Werkzeughälfte während des Umformprozesses gezielt gesteuert bzw. geregelt werden. Insbesondere kann die Werkzeughälfte beim Produktionsstart gezielt erwärmt werden, um das Erreichen der Gleichgewichtstemperatur zu beschleunigen. Die Heizung kann z. B. durch eine oder mehrere in die Werkzeughälfte eingebettete Heizpatrone(n) und/oder durch ein die Werkzeughälfte durchströmendes Medium (z. B. Öl, Wasser etc.) erreicht werden. Mit Hilfe eines Mediums, das Hohlräume im Werkzeughälfte durchströmt, kann weiterhin eine gezielte Temperierung (lokale Aufheizung oder Abkühlung) der Werkzeughälfte erreicht werden.additionally to the local design of the heat conduction properties of Tool half can be the tool half local Have tempering. With the help of this additional Tempering elements can be the (local) temperature of the mold half controlled or regulated during the forming process become. In particular, the tool half at the start of production to be heated specifically to reach the equilibrium temperature to accelerate. The heater can z. B. by one or more embedded in the tool half cartridge heater (s) and / or through a medium flowing through the tool half (eg oil, water etc.). With help of a Medium, which flows through cavities in the tool half, can furthermore a targeted temperature control (local heating or cooling) the mold half can be achieved.
