" Tafelschere zum verwindungsfreien Schneiden " " Guillotine shears for torsion-free cutting "
Bei Tafelscheren war bisher beim Schneiden schmaler Blechstreifen der Nachteil, daß eine große Verwindung in Kauf genommen werden mußte. Eine Korrektur durch Veränderung des Schnittwinkels ist durch das starke Ansteigen der Schnittkräfte begrenzt.The disadvantage of using guillotine shears when cutting narrow strips of sheet metal was that a large amount of twisting had to be accepted. Correction by changing the cutting angle is limited by the sharp increase in cutting forces.
Um dies zu verhindern, wird nach dem Erfindungsgedanken der Messerbalken 1 und damit verbunden das Obermesser 2 ohne MesserSteigung horizontal angeordnet. Der Messertisch 3 und damit verbunden das Untermesser 4, ist festehend mit dem Scherenrahmen und Ständer 5 mit der zum geraden Übermesser 2 ..rforderlichen Messersteigung angeordnet.In order to prevent this, according to the inventive concept, the knife bar 1 and the connected upper knife 2 are arranged horizontally without knife pitch. The knife table 3 and the connected lower knife 4 are fixed to the scissor frame and stand 5 with the knife pitch required for the straight upper knife 2.
Um den schon durch die gerade Anordnung des bewegten Obermessers 2 bewirkten Richtvorgang der Blechstreifen noch zu unterstützen,ist der Blechhalter, zusammengestzt, aus der Blechhalterwange 7 und aus mehreren über die Arbeitsbreite angeordneten doppeltwirkenden Hydraulikzylinder 6 in der Tischmessersteigung, parallel dazu geneigt angeordnet.In order to further support the straightening process of the sheet metal strips, which is already effected by the straight arrangement of the moving upper knife 2, the sheet metal holder, composed of the sheet metal holder cheek 7 and several double-acting hydraulic cylinders 6 arranged across the working width in the table knife pitch, is arranged inclined parallel to it.
Hierbei ist die Blechhalterwange 7 über Zuglaschen unmittelbar an den Stirnflächen
des Messertisches 3 befestigt.
Die Fig. 1 zeigt die Vorderansicht einer Tafelschere Die Fig. 2 zeigt die Seitenansicht einer Tafelschere, wobei die Schrägstellung
des Messertisches 3 mit dem Messer &lgr; erkennbar ist.The sheet metal holder cheek 7 is attached directly to the front surfaces of the knife table 3 via pull tabs.
Fig. 1 shows the front view of a guillotine shear. Fig. 2 shows the side view of a guillotine shear, where the inclination of the knife table 3 with the knife &lgr; can be seen.
Die Fig. 3 zeigt einen der mehrere über der Arbeits'breitt angeordneten doppelt wirkenden Hydraulikzylinder b, die Blechhalterwange 7 und das Untermesser Hierbei ist die Darstellung des letzten an der rechten Seite angeordneten Zylinders bezogen.Fig. 3 shows one of the several double-acting hydraulic cylinders b arranged over the working width, the sheet metal holder cheek 7 and the lower knife. The illustration here refers to the last cylinder arranged on the right-hand side.
Bei der Beschreibung ist der Messerbalken mit 1, das Obermesscr mit 2, das Untermesser mit 4, der Messertisch mit 3, der Scherenrahmen und Ständer mit die doppeltwirkenden Hydraulikzylinder als Einzelblechhalter wirksam mit 6 und die Blechhalterwange mit 7 bezeichnet.In the description, the knife bar is designated with 1, the upper knife with 2, the lower knife with 4, the knife table with 3, the scissor frame and stand with the double-acting hydraulic cylinders effective as single sheet holders with 6 and the sheet holder cheek with 7.
Der Erfindungsgedanke bezieht sich nicht nur auf die Darlegung in der Patentbeschreibung, sondern erstrekt sich auf jegliche Abwandlung.The inventive concept does not only refer to the explanation in the patent description, but extends to any modification.
