Description
Die Erfindung betrifft eine Schere zum Schneiden von Blech, Bandeisen, Profileisen u. dgl. Das Neue der Erfindung besteht darin, daß das mittelbar den Messerschlitten antreibende Hebelpaar durch zwei Paar Zwischenhebel mit dem zweiarmigen Handhebel verbunden ist, dessen kürzerer Arm sich beim Niederschwingen mit beiderseits angeordneten Rollen gegen das eine Paar der Zwischenhebel legt.The invention relates to scissors for cutting sheet metal, strip iron, profile iron The novelty of the invention is that the indirectly driving the knife carriage Pair of levers by two pairs of intermediate levers with the two-armed hand lever is connected, the shorter arm of which is arranged on both sides when swinging down Rolls against which a pair of intermediate levers puts.
Bei den Scheren für größere Leistungen ist mit einer einfachen Hebelübersetzung wie bei Meineren Leistungen nicht auszukommen. Es ist aus diesem Grunde bei' manchen Scheren ein1 Zahnbogen angebracht, in dessen Zähne ein am Handhebel befindliches Zahnrad eingreift.With the scissors for larger performances, a simple leverage as with my performances is not enough. It is appropriate for this reason, in 'some scissors 1 a dental arch, engages an onboard hand lever gear in the teeth.
Es sind auch Scheren mit Handhebel und Messerhebel eingeschalteten Zwischenhebeln bekannt; diese sowohl als auch die oben erwähnten Scheren mit Antrieb durch Zahnrad und Zahnbogen haben aber den Übelstand, daß der Handhebel einen großen Ausschlag machen muß, um den nötigen Hub des Messers zu bekommen.There are also scissors with hand lever and knife lever switched on intermediate levers known; this as well as the above mentioned scissors with gear drive and dental arches have the disadvantage that the hand lever has a large deflection must do to get the necessary stroke of the knife.
Dieser Übelstand ist durch vorliegende Erfindung beseitigt.This drawback is eliminated by the present invention.
Die Zeichnung stellt ein Ausführungsbeispiel der Schere dar, und zwar in Fig. 1 in Ansicht, in Fig. 2 in Draufsicht; Fig. 3 zeigt eine Einzelheit.The drawing shows an embodiment of the scissors, namely in Fig. 1 in View, in Fig. 2 in plan view; Fig. 3 shows a detail.
Der. Messerschlittem α wird in bekannter Weise durch die um den Bolzen b drehbaren Hebel c unter Einschaltung der Hebel d auf und ab bewegt.Of the. The knife slide α is moved up and down in a known manner by the lever c rotatable about the bolt b, with the engagement of the lever d .
An einem Vorbau e der Schere sind die Hebel/ drehbar gelagert, und an diese sind Hebel g angelenkt, welche mit dem Ende der Hebel c und zugleich mit dem Handhebel h drehbar verbunden sind. Der Handhebel h ist als zweiarmiger Hebel ausgebildet. Sein kürzeres Ende trägt auf jeder Seite eine Rolle i, die gegen die Unterseite der Hebel f drückt. Die Unterseite der Hebel f ist zweckmäßig bogenförmig.The levers / are rotatably mounted on a stem e of the scissors, and levers g are articulated to these, which are rotatably connected to the end of the lever c and at the same time to the hand lever h. The hand lever h is designed as a two-armed lever. Its shorter end carries a roller i on each side, which presses against the underside of the lever f. The underside of the lever f is expediently arcuate.
Wird der Handhebel h heruntergedrückt, so werden auch, da die Rollen* gegen die Hebel f drücken, diese sowie auch die Hebel g und c abwärts bewegt und gelangen in die in Fig. ι strichpunktierte Lage. Hierdurch 5« wird dann auch der Messerschlitten zum Schnitt abwärts bewegt.If the hand lever h is pressed down, then, since the rollers * press against the lever f , these and also the levers g and c are moved downwards and move into the position shown in phantom in FIG. As a result, the knife carriage is then also moved downwards for the cut.
Wie aus der Fig. 1 ersichtlich ist, ist der Ausschlag des Handhebels nicht groß. Dieser Hebel kann deshalb recht lang gemacht werden, ohne daß die Arbeit damit erschwert wird.As can be seen from FIG. 1, the deflection of the hand lever is not great. This Lever can therefore be made quite long without making work difficult will.
Mit der Schere kann auch in bekannter Weise eine Lochstanze verbunden sein.A hole punch can also be connected to the scissors in a known manner.
