Abstract

Die Erfindung betrifft ein Verfahren bzw. eine Vorrichtung zum Tiefziehen von Blechformteilen, bei welchem die Blechformteile zumindest einem Tiefzug in einer Tiefziehpresse unterworfen werden. Erfindungsgemäß ist dieses Verfahren bzw. diese Vorrichtung zum Tiefziehen von Blechformteilen im Hinblick auf eine gezielte Entfestigung von kaltverfestigten Bereichen der Blechformteile ohne Unterbrechung des Umformvorgangs und ohne unerwünschte Entfestigung gezielt kaltverfestigter Bereiche bei gleichzeitiger Vermeidung von unerwünschter Grobkornbildung dadurch ausgestaltet, daß die Blechformteile in der Tiefziehpresse örtlich begrenzt entfestigungsgeglüht werden.

Figure 00000001
The invention relates to a method and a device for deep drawing sheet metal parts, in which the sheet metal parts are subjected to at least one deep drawing in a deep drawing press. According to the invention, this method or device for deep-drawing sheet metal parts with a view to targeted softening of work-hardened areas of the sheet-metal parts without interrupting the forming process and without unwanted softening of targeted work-hardened areas while avoiding undesired coarse grain formation in that the sheet-metal parts are localized in the deep-drawing press limited softening annealing.
