Abstract

Zum Tiefziehen von ebenen Blechen zu Formteilen mit am Formteilboden angeordneten, lokalen Formkonturen mit kleinen Formradien wird das randseitig eingespannte Blech mittels eines die Kontur des Formteils aufweisenden Formstempels gegen ein fluides Wirkmedium umgeformt. Um die lokalen Formkonturen bei geringen Wirkmediumdruck auszuformen, wird das Blech im Bereich der lokalen Formkonturen gegen im Wirkmedium ortsfest positionierte, elastisch nachgiebige Festkörper-Formelemente umgeformt. Die Formelemente bestehen vorzugsweise aus einem elastisch verformbaren, verschleißfesten Material.

Figure 00000001
In order to deep-draw flat metal sheets into molded parts with local molded contours with small mold radii arranged on the molded part base, the sheet metal clamped on the edge is shaped against a fluid active medium by means of a molded die having the contour of the molded part. In order to form the local shape contours at low active medium pressure, the sheet metal in the area of the local shape contours is reshaped against elastically resilient solid-form elements which are positioned in the active medium. The shaped elements preferably consist of an elastically deformable, wear-resistant material.
