Abstract

Verfahren zur Herstellung eines komplexen Blechformteils mittels pressengebundenem Werkzeug, mit:
- Einlegen eines Blechs (M) und Abwärtshub des Werkzeugoberteils (120), wobei das Blech (M) im Randbereich zwischen Matrizenring (160) und Niederhalter (140) geklemmt wird;
- weiterer Abwärtshub, wobei das Blech (M) zuerst über ausgefahrene Stempeleinsätze (131, 132, 133) gezogen wird und dabei lokale Materialbevorratungen im Blech (M) erzeugt werden;
- weiterer Abwärtshub bis Matrizenring (160) und Niederhalter (140) ihre Totpunkte erreichen, wobei gleichzeitig die Stempeleinsätze (131, 132, 133) aktiv zurückbewegt werden und die lokalen Materialbevorratungen freigeben und wobei das Blech (M) bereits bereichsweise zwischen Matrizenring (160) und Stempel (130) ausgeformt wird;
- weiterer Abwärtshub bis die Matrize (150) ihren Totpunkt erreicht, wobei das Nachfließen aus dem Randbereich verhindert und das Blech (M) lediglich unter Ausnutzung der lokalen Materialbevorratungen zwischen Matrize (150) und Stempel (130) fertig ausgeformt wird.
Ferner zur Ausführung dieses Verfahrens geeignetes Werkzeug (100).
