Title
(DE) HEBELÜBERSETZTE SCHNEIDVORRICHTUNG
(EN) LEVER-TRANSLATED CUTTING DEVICE
(FR) DISPOSITIF DE COUPE À RAPPORT DE LEVIER
Abstract
(DE)
Die Erfindung betrifft eine Schneidvorrichtung mit einem Gestell (1), einem daran um eine erste Schwenkachse (2) schwenkbar befestigten Schneidmesser (3) und einem Untersetzungsgetriebe (4, 5), welches jeweils die Hinschwenkbewegung mehrerer hintereinander ausgeführter Hin- und Rückschwenkbewegungen eines Antriebsarmes (6) in eine Schneidschwenkbewegung des Schneidmessers (3) überträgt. Zur Verbesserung der Handhabbarkeit ist eine Schneidmesser-Rückschwenkeinrichtung (20, 21, 22, 23) vorgesehen, mit der das Schneidmesser (3) von einer Schwenkendstellung in eine Ausgangsstellung zurückgeschwenkt werden kann. Die Rückschwenkeinrichtung besitzt insbesondere ein unter Ausbildung eines Freigangs am Schneidmesser (3) angreifendes Zugglied (20).
(EN)
The invention relates to a cutting device, comprising a frame (1), a cutting blade (3), which is fastened to the frame for pivoting about a first pivot axis (2), and a reduction transmission (4, 5), which converts each forward pivoting movement of a plurality of successively performed forward pivoting movements and backward pivoting movements of a drive arm (6) into a cutting pivoting movement of the cutting blade (3). In order to improve the ease of handling, a cutting-blade back-pivoting apparatus (20, 21, 22, 23) is provided, by means of which the cutting blade (3) can be pivoted back from a pivoting end position to an initial position. The back-pivoting apparatus has, in particular, a tension element (20), which acts on the cutting blade (3) in such a way that a clearance is formed.
(FR)
L'invention concerne un dispositif de coupe comportant un bâti (1), une lame de coupe (3) fixée sur celui-ci de manière à pouvoir pivoter autour d'un premier axe de pivotement (2) et un engrenage réducteur (4, 5), lequel transfert respectivement le mouvement de pivotement de plusieurs mouvements de pivotement va-et-vient d'un bras d'entraînement ( 6) dans un mouvement de pivotement de coupe de la lame de coupe (3). L'invention vise à améliorer la facilité de manipulation. À cet effet, un dispositif de pivotement en arrière de la lame de coupe (20, 21, 22, 23) est prévu, au moyen duquel la lame de coupe (3) peut être pivotée en arrière d'une position finale de pivotement à une position initiale. Ledit dispositif de pivotement en arrière comporte en particulier un organe de traction (20) venant en prise, tout en formant un jeu, avec la lame de coupe (3).
