Abstract
Description
Tisch- und Messerbalkenkonstruktion zum verwindungsfrei-Table and knife bar construction for torsion-free
en Schnelden an Tafelscheren Bei Tafelscheren war @isher 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.en Cutting on guillotine shears @isher was cutting with guillotine shears narrow sheet metal strips have the disadvantage that a large amount of torsion is accepted had to become. A correction by changing the cutting angle is possible through the strong increases in cutting forces are limited.
Um dies zu verhindern, kommt nach dem Erfindungsgedanken die Messersteigung an dem sich bewegenden Messerbalken (1) zum Fortfall und der iqessertisch (3) erhält die erforderliche Steigung.In order to prevent this, the knife pitch comes after the idea of the invention on the moving cutter bar (1) to be eliminated and the iqessertisch (3) received the required slope.
Dies hat den Vorteil, die der abzuschneidende Blechstreifen während dem Schnittvorgang durch das gerade Obermesser (2) wieder gerichtet wird.This has the advantage that the metal strip to be cut off during the cutting process is straightened again by the straight upper knife (2).
Figur 1 zeigt die Vorderansicht einer Tafelschere, wobei der Blechniederhalter entfernt ist.Figure 1 shows the front view of a pair of guillotine shears, the sheet metal hold-down away.
Figur 2 zeigt die Seitenansicht einer Tafelschere, wobei die Schrägstellung des Messertisches (3) mit dem Messer (1) erkennbar ist, Bei der Beschreibung ist der Messerbalken mit 1, das Obermesser mit 2, das Untermesser mit 4, und der Messertisch mit 3 bezeichnet, Der Erfindungsgedanke bezieht sich nicht nur auf die Darlegung in der Patentbeschreibung, sondern erstreckt sich auch auf jegliche AbwandlungFigure 2 shows the side view of a pair of guillotine shears, the inclined position of the knife table (3) with the knife (1) is recognizable the cutter bar with 1, the upper knife with 2, the lower knife with 4, and the knife table denoted by 3, the idea of the invention relates not only to the presentation in the patent specification, but also extends to any modification
