Abstract

Zur Erhöhung der Schnittqualität, insbesondere beim Stanzen hochfester martensitischer Werkstoffe oder auch beim Stanzen dicker Bleche, wird eine Blechhalteeinrichtung (2) vorgesehen, die das betreffende Werkstück (16) während des Stanzvorgangs fest einspannt. Die Spannkraft wird auf bis zu 40 % oder mehr Prozent der Stößelkraft erhöht. Insbesondere kann die von der Blechhalteeinrichtung (21) ausgeübte Kraft während des Werkstückdurchbruchs nochmals erhöht werden. Einerseits verbessert sich dadurch die Schnittqualität während sich andererseits eine effiziente Schnittschlagverhinderung an der Presse ergibt. Ein Schnittschlag ist wesentlich geschwächt oder tritt nicht auf.
