Abstract

Die Erfindung betrifft das automatisierte Härten von einzelnen Werkstücken, insbesondere Stahlblechen. The invention relates to the automated hardening of individuals Workpieces, especially sheet steel.

Es sollen Stahlbleche derart gehärtet werden, daß ihr Randbe­ reich gegenüber dem übrigen Stahlblech eine höhere Härte und eine höhere Verschleißfestigkeit aufweist, im übrigen Stahl­ blech eine hinreichende Federwirkung erreicht wird und dabei das Stahlblech weitestgehend verzugsfrei bleibt. Erfindungsgemäß wird ein Stahlblech (3) in einem Warmbad (1) unter Verwendung von Preßplatten (4) zur Verhinderung des Ver­ zuges derart gehärtet, daß das Stahlblech (3) einem Warmbad (1) zugeführt wird, hier mittels den Randbereich freilassender Preß­ platten (4) in der vorgesehenen Form gehalten wird, wobei spä­ testens gleichzeitig mit dem Anpreßvorgang über eine Verdrängungs­ einrichtung (6) dem Randbereich des Stahlbleches (3) Abschreck­ medium (2) aus dem Warmbad mit hoher Strömungsgeschwindigkeit zugeführt wird. Steel sheets are to be hardened in such a way that their edge rich compared to the rest of the steel sheet and has a higher wear resistance, steel otherwise a sufficient spring action is achieved while doing so the steel sheet remains largely free of distortion. According to the invention, a steel sheet (3) is placed in a warm bath (1) using press plates (4) to prevent ver addition hardened in such a way that the steel sheet (3) a warm bath (1) is supplied, here by means of the press leaving the edge region free plates (4) is held in the intended shape, with late at the same time as the pressing process via a displacement device (6) the edge region of the steel sheet (3) quenching medium (2) from the warm bath with high flow velocity is fed.
