Abstract

Es wird eine hydraulische Presse vorgeschlagen, die vor, während und nach dem Arbeitshub ständig vorge­ spannt ist, so daß von einer dynamischen Vorspannung der Presse gesprochen werden kann. Durch diese dynami­ sche Vorspannung wird ein ständiges Spannen und Ent­ spannen, wie dies bei herkömmlichen Pressen auftritt vermieden, wodurch sich eine Energieeinsparung und eine Schnittschlagdämpfung ergeben.
