Description

Häufig sollen Blechscheren lediglich Blechtafeln besäumen, d.h. nur an den Kanten beschneiden.Often, tin snips should only trim sheet metal, i.e. only at the edges trimming.

Die Erfindung betrifft eine derartige Schere, die außerordentlich 'einfach, leicht und daher billig gegenüber Scheren ist, die auch die Aufgabe haben, Blechtafeln mitten durchzuschneiden.The invention relates to such scissors, which are extremely 'simple, light and is therefore cheap compared to scissors, which also have the task of centering sheet metal cut through.

Gemäß der Erfindung ist die das Obermesser tragende und am Untermesser entlang führende Katze bügeiförmig derart gestaltet, daß sie 'den am Obermesser auftretenden Schneiddruck unmittelbar auf den Untermesserträger überträgt.According to the invention, the one carrying the upper knife and along the lower knife leading cat bow-shaped designed so that they 'occur on the upper knife Transfers cutting pressure directly to the lower blade carrier.

Die Erfindung ist durch die Zeichnung beispielsweise dargestellt, und zwar ist Abb. ι eine Seitenansicht, Abb. 2 eine Stirnansicht zum Teil im Schnitt.The invention is illustrated by the drawing, for example, namely is Fig. Ι a side view, Fig. 2 is a front view in part Cut.

An den Ständern 1, 1 ist der Untermesserträger 2 sowie das die Schneidkatze 3 für das Obermesser 4 tragende kräftige Führungsrohr s gelagert. Die Katze 3 mit dem Messer 4 wird an dem Untermesser 6 entlanggeführt, z. B. mittels in der Zeichnung nur schematisch angedeuteter Galischer Kette 7, die über an den Ständern 1 gelagerte Rollen 8, 8 geführt und z. B. von einer Rolle 9 aus angetrieben wird.On the stands 1, 1 is the lower knife carrier 2 and the trolley 3 for the upper knife 4 supporting strong guide tube s stored. The cat 3 with the knife 4 is guided along the lower knife 6, for. B. means in the drawing only schematically indicated Galic chain 7, which is guided over rollers 8, 8 mounted on the uprights 1 and Z. B. is driven by a roller 9 from.

Die Katze 3 ist gemäß der Erfindung bügeiförmig derart ausgebildet, daß sie den Untermesserträger 2 untergreift. Sie trägt vorzugsweise zwei Druckrollen 10, die auf einer am Untermesserträger angebrachten Stahlschiene 11 laufen.According to the invention, the cat 3 is bow-shaped in such a way that it supports the lower blade carrier 2 reaches below. It preferably carries two pressure rollers 10 on one The steel rail 11 attached to the lower knife carrier run.

Die zu besäumenden Blechplatten werdein auf den Tisch 12 aufgelegt und zwischen dem Untermesser 6 und dem daran entlangbewegten kreisförmigen Obermesser 4 beschnitten. Die Katze 3 wird dabei in bekannter Weise an dem Rohr 5 geführt. Zur Aufnahme des Schneiddruckes ist aber nicht die Anordnung eines oberen Balkens erforderlich. Dieser überträgt sich vielmehr mittels des bügelförmigen Teiles der Katze und der Druckrollen 10, 10 unmittelbar auf den Untermesserträger 2. Es erfolgt somit ein Aus- ■ gleich des Schneiddruckes gegen Untermesser und Obermesser, und auch der Untermesserträger 2 wird nicht auf seiner ganzen Länge auf Biegung beansprucht, sondern nur zwischen den beiden Rollen io, 10 und kann gleichfalls erheblich leichter ausgeführt werden. Auch kann von Verspannungen und Verstrebungen an der Maschine abgesehen werden. The sheet metal plates to be trimmed are placed on the table 12 and between the Lower knife 6 and the circular upper knife 4 moved along it trimmed. The cat 3 is guided on the pipe 5 in a known manner. To record the cutting pressure does not require the arrangement of an upper beam. Rather, this is transmitted by means of the bow-shaped part of the cat and the Pressure rollers 10, 10 directly on the lower knife carrier 2. There is thus an equalization of the cutting pressure against the lower knife and upper knife, and also the lower knife carrier 2 is not over its entire length stressed on bending, but only between the two roles io, 10 and can can also be carried out much more easily. Also can of tension and bracing on the machine.
