Bekannte Möglichkeiten den Dehnungsverlauf im Bodenbereich zu beeinflussen sind zum Beispiel eine besondere geometrische Gestaltung des Bodens. Des Weiteren kann durch einen gezielten Reibungsparameter der Oberfläche des Stempels zur Blechoberfläche der Blechfluss und damit die Zielgrößen beeinflusst werden.Known options To influence the strain course in the floor area are, for example a special geometric design of the floor. Furthermore can be determined by a specific friction parameter of the surface of the Stamp to the sheet metal surface the sheet metal flow and thus the target variables are influenced.
Weiterhin sind Verfahren bekannt bei denen in mehreren Arbeitsgängen im Folgeverbund der Zielbereich der Bodenfläche zunächst vorgeformt werden.Farther Methods are known in which in several operations in Follow-on composite of the target area of the bottom surface are first preformed.
Es ist nun ein Verfahren bekannt bei dem durch mehrfaches Wölben (Deformieren) und Rückwölbens (Reformieren) des Ziehteilbodens eine entstehende Oberflächenvergrößerung im Boden eintritt. Diese Oberflächenvergrößerung wird Verfahrensbedingt während des Reformieren des Ziehteilbodens durch Überlagerung von Zugspannungen in die Blechteilzarge überführt, wodurch
- a) die Einsatzplatine verkleinert werden kann
- b) die Zargenhöhe gesteigert wenden kann oder
- c) die Festigkeit im Boden gesteigert werden kann.
- a) the insert board can be downsized
- b) can increase the frame height increased or
- c) the strength in the soil can be increased.
Ein Arbeitszyklus besteht aus Deformieren und Reformieren des Ziehteilbodens und wird als Penetration des Ziehteilbodens bezeichnet. Das Ziehverfahren nennt sich „Penetrations-Tiefziehen".One Duty cycle consists of deforming and reforming the drawing part floor and is referred to as Penetration of Ziehteilbodens. The drawing process is called "penetration deep drawing".
Der Ziehteilboden kann einmalig oder mehrmalig während eines Tiefzuges penetriert werden.Of the Drawing part floor can be penetrated once or several times during a deep drawing become.
