Description

Die vorstehende Erfindung betrifft eine Maschine zum Biegen von strangförmigem Material, wie z.B. Rohren, Stangen Profilen oder Metalldraht.The above invention relates to a machine for bending of strand-like material, e.g. Pipes, rods Profiles or metal wire.

Es ist aus dem Stand der Technik bekannt geworden, zum Biegen von Rohren, Stangen, Profilen oder Metalldraht Maschinen einzusetzen, die aus einem Maschinenbett bestehen, wobei dem Maschinenbett z.B. ein Rohr zugeführt wird, dessen vorderes Teil einem Biegevorgang zu unterziehen ist.It has become known from the prior art for Bending pipes, bars, profiles or metal wire Use machines that come from a machine bed exist, the machine bed e.g. fed a pipe becomes, the front part of a bending process undergo.

Für den Vorschub des Rohres ist ein gesteuert verfahrbarer Wagen vorgesehen, der entlang paralleler Führungen des Maschinenbettes verfahrbar ist. Der Wagen ist mit einem Spannfutter versehen, das es ermöglicht, das Rohr zu spannen. Ferner erlaubt das Spannfutter eine präzise, gesteuerte Drehbewegung des Rohres um dessen Längsachse.A controlled movable one is for the advance of the pipe Carriage provided along the parallel guides of the Machine bed is movable. The car is with one Provided chuck that allows the pipe to be closed tighten. Furthermore, the chuck allows a precise, controlled rotation of the tube around its longitudinal axis.

Am vorderen Ende der Biegemaschine sind in übereinander angeordneter Lage mehrere Biegeformen vorgesehen, die wahlweise in Übereinstimmung mit der Achse des zu biegenden Rohes positionierbar sind. Dadurch eröffnet sich die Möglichkeit, unter Zuhilfenahme eines bekannten, schwenkbaren Biegearmes, in Übereinstimmung mit dem vorderen Rohrstück, Biegevorgänge durchzuführen, die die Erstellung von Biegungen mit unterschiedlichen Radien und unterschiedlichem Krümmungsverlauf ermöglichen.At the front end of the bending machine are one on top of the other arranged location provided several bending shapes that optionally in accordance with the axis of the bend Raw can be positioned. This opens the Possibility, with the help of a known, pivotable bending arm, in accordance with the front pipe section to perform bending operations that the Creation of bends with different radii and allow different curvature.

Die modernen Biegemaschinen der beschriebenen Art weisen in Übereinstimmung mit dem vorderen Ende des Rohres auch häufig Einrichtungen zum Abtrennen des Rohrstückes, welches den Biegevorgängen unterzogen wurde, auf.The modern bending machines of the type described have in Match the front end of the tube too often facilities for severing the pipe section, which has undergone the bending processes.
