Abstract

Eine Warmformlinie zur Herstellung von warmumgeformten und pressgehärteten Blechprodukten aus Metallplatinen 6 umfasst eine Heizstation 1 und eine Umformstation 2. Die Heizstation 1 weist ein Unterwerkzeug 3 und ein Oberwerkzeug 4 auf, zwischen denen eine Metallplatine 6 zum Erwärmen aufgenommen wird. Die Erwärmung bzw. Aufheizung einer Metallplatine 6 in der Heizstation 1 erfolgt durch mittelbare Widerstandserwärmung. Die Wärme wird außerhalb der Metallplatine 6 erzeugt und gelangt durch Wärmeleitung in die Metallplatine 6 selber. Hierzu weist das Unterwerkzeug 3 und/oder das Oberwerkzeug 4 eine elektrische Widerstandsheizung 7 mit zumindest einem Flächenheizelement auf. Erfindungsgemäß ist das Flächenheizelement eine Heizplatte 8 mit einem Plattenkörper 9 aus einem elektrisch leitfähigen Material, wobei der Plattenkörper 9 als Heizleiter 11 ausgebildet ist. Hierzu ist der Plattenkörper 9 geschlitzt und beispielsweise mit einem Schlitz 10 versehen, welcher sich über die Dicke d des Plattenkörpers 9 erstreckt.
