Description
Rohrbiegezange Es sind Rohrbiegezangen bekannt, bei denen die eine Maulhälfte ein Druckstück bildet, während die andere zwei etwas seitlich zum Druckstück liegende Backen trägt, die auch als Rollen ausgebildet sein können. Mit den bekannten Zangen lassen sich jedoch entweder nur geringe Winkel biegen, oder es genügt nicht der einfache Druck auf die Handgriffe der Zangen. Die Zange nach der Erfindung ermöglicht es, .ein Rohr mit einem Druck bis zu einem Winkel von 9o ° zu biegen.Pipe bending pliers There are pipe bending pliers known in which one Half of the mouth forms a pressure piece, while the other two are slightly to the side of the pressure piece carries lying jaws, which can also be designed as rollers. With the known However, pliers can either only be bent at small angles or it is not sufficient the simple pressure on the handles of the pliers. The pliers according to the invention make it possible it is to bend a pipe with a pressure up to an angle of 90 °.
An dem äußeren Ende der beiden kniehebelförmigen Handgriffe a sind zwei Halter b angelenkt, welche j e eine Profilrolle c tragen. Einerseits an den Rollenhaltern b und andererseits an den Kniehebeln a sind Streben d angelenkt. Zwei Stutzen e tragen das ebenfalls profilierte, gezahnte Druckstück f, das rückwärts in einer Führung g genau senkrecht geführt wird.At the outer end of the two toggle-shaped handles a , two holders b are articulated, each of which carries a profile roller c. Struts d are hinged on the one hand to the roll holders b and on the other hand to the toggle levers a. Two nozzles e carry the likewise profiled, toothed pressure piece f, which is guided backwards in a guide g exactly vertically.
Abb. x zeigt die geschlossene Rohrbiegezange, Abb. 2 die geöffnete Rohrbiegezange. Soll beispielsweise ein Rohr für elektrische Installationen an irgendeiner Stelle gebogen werden, so wird das Rohr einfach in die Nut des Druckstückes, also zwischen Rollen und Druckstück, gelegt, darauf die Zange zugedrückt, wobei die Rollen gleichmäßig seitlich ziehend und entgegen dem Druckstück über das Rohr rollen. Das Rohr wird also mit einem Druck, ohne zu knicken oder plattgedrückt zu werden, gebogen. Das gezahnte Druckstück sorgt für gleichmäßige Verteilung des Materials und ist in verschiedenen Größen leicht auszuwechseln. Ist der Bogen gedrückt, dann wird die Zange wieder geöffnet und kann dann sehr leicht vom Rohr wieder abgenommen werden.Fig. X shows the closed pipe bending pliers, Fig. 2 the open one Pipe bending pliers. For example, if a pipe for electrical installations is to be attached to any Place, the pipe is simply in the groove of the pressure piece, so between the rollers and the pressure piece, and then the pliers are pressed shut, the rollers Pulling evenly sideways and rolling against the pressure piece over the pipe. That Pipe is bent with one pressure without kinking or being pressed flat. The toothed pressure piece ensures even distribution of the material and is easy to change in different sizes. If the bow is pressed, then the pliers are opened again and can then be easily removed from the pipe.
