Abstract
Verfahren zum Pressformen und Härten eines Werkstücks aus Stahl in einer Gesenkpresse, wobei das Werkstück (4) auf seinen Austenitisierungstemperaturbereich erwärmt wird, anschließend zwischen ein Obergesenk (2) und ein Untergesenk (3) eines Umformwerkzeugs (1) der Gesenkpresse gelegt wird, nachfolgend das Werkstück (4) zwischen dem Obergesenk (2) und dem Untergesenk (3) warm umgeformt wird und anschließend durch unmittelbaren Kontakt mit einem Kühlmittel (6) innerhalb des Umformwerkzeugs (1) gehärtet wird. Die Gesenke (2, 3) werden nach dem Umformen teilweise wieder auseinander gefahren, so dass das Kühlmittel (6) durch den enstehenden Spalt (10, 11) zwischen den Gesenken (2, 3) und dem Werkstück (4) in den Formhohlraum (9) einströmt. A method of press-forming and hardening a steel workpiece in a swaging press, wherein the workpiece (4) is heated to its austenitizing temperature range, then placed between an upper die (2) and a lower die (3) of a swaging press forming tool (1), hereinafter Workpiece (4) between the upper die (2) and the lower die (3) is hot formed and then cured by direct contact with a coolant (6) within the forming tool (1). The dies (2, 3) are partially moved apart again after the forming, so that the coolant (6) through the resulting gap (10, 11) between the dies (2, 3) and the workpiece (4) in the mold cavity ( 9) flows in.
