Abstract

The tube (1) which is to be bent is pushed through the bending machine between the rollers (3) and in inductive heater (4). The end of the pipe is gripped by jaws (6) which protrude from a bending arm (5). The jaws are mounted on the bending arm in such a way that they can be moved clear from the tube, so that the tube can be slid out of the machine along its longitudinal axis and the next tube can be inserted in the machine.

Description

"Spannvorrichtung für Rohrbiegemaschinen"Clamping device for tube bending machines

Gegenstand der Erfindung ist eine Spannvorrichtung für Rohrolegemaschinen zum Biegen von insbesondere induktiv ersermten Rohren.The invention relates to a clamping device for pipe laying machines for bending pipes, in particular inductively grounded.

Es ist bekannt, Rohre nach induktiver Erwärmung fest in einem Biegearm eingespannt zu biegen. Bei diesem Vorgang wird das örtlich ervewate Rohr durch eine achsiale Vorschubkraft und dee Zwangsführung des Biegearmes zu einem Bogen geformt.It is known to fix pipes firmly in a bending arm after induction heating clamped to bend. During this process, the locally ervewate pipe is passed through a axial feed force and the forced guidance of the bending arm formed into an arc.

nachteilig bei diesem Biegevorgang ist, daß es sehr umständlich und zeitaufwendig ist, den Rohrbogen aus der Spannvorrichtung zu lösen und aus der Biegevorrichtung zu entnehmen.The disadvantage of this bending process is that it is very cumbersome and it is time consuming to loosen the pipe bend from the jig and from the bending device refer to.

Aufgabe der Erfindung ist es, eine Spannvorrichtung zu schaffen, mit der das Lösen des Biegegutes vom Biegearm sowie das Herauswahren des fertig gebogenen Rohres aus der Biegevorrichtung vereinfacht und beschleunigt wird.The object of the invention is to create a clamping device with the loosening of the bending material from the bending arm as well as keeping out the finished bent Pipe from the bending device is simplified and accelerated.

Zur Lösung dieser Aufgabe wird erfindungsgemäß eine Spannvorrichtung vorgeschlagen, die gekennzeichnet ist durch eine im Biegearm gelagerte Spannvorrichtung, die um Spannlänge und Übermaß verschiebbar angeordnet ist. Die Spannung kann sowohl außen und/oder innen erfolgen.According to the invention, a clamping device is used to achieve this object proposed, which is characterized by a clamping device mounted in the bending arm, which is arranged to be displaceable by the span length and oversize. The tension can be both outside and / or inside.

Durch die erfindungsgemäße Spannvorrichtung wird eine schnellere Freigabe des Bogens erzielt, so daß der fertige Rohrbogen ohne weitere Maßnahmen aus der Biegevorrichtung herausgefahren und das nächste Rohr in die Biegevorrichtung eingefahren werden kann.The clamping device according to the invention enables faster release achieved the arch, so that the finished pipe bend without further measures from the Bending device extended and the next pipe inserted into the bending device can be.

Die bisher erforderlichen Nebenzeiten werden durch die erfindungsgemäße Vorrichtung erheblich verkürzt.The non-productive times previously required are reduced by the inventive Device shortened considerably.

Die erfindungsgemäße Vorrichtung kann als Außen- und/oder Innenspanneinrichtung ausgelegt sein und ist für jeden Biegewinkel geeignet.The device according to the invention can be used as an external and / or internal clamping device designed and is suitable for every bending angle.

In der beigefügten Zeichnung sind die verschiedenen Vorgänge beim Biegen eines Rohres schematisch dargestellt.In the attached drawing are the various operations at Bending a pipe shown schematically.

Es zeigen: Figur 1 eine Vorrichtung vor dem Biegevorgang, Figur 2 eine Vorrichtung nach dem Biegevorgang, Figur 3 das freigegebene Biegegut.The figures show: FIG. 1 a device before the bending process, FIG. 2 a device after the bending process, Figure 3 the released material to be bent.

In den Darstellungen der Figuren 1 und 2 wird das Rohr 1 mit Hilfe einer Druckeinrichtung 2 durch die Biegerollen 55 3 und über induktive Heizeinrichtung 4 gedrückt, wobei es an seinem Ende fest in den Biegearm 5 eingespannt ist.In the representations of Figures 1 and 2, the pipe 1 is with the help a pressure device 2 by the bending rollers 55 3 and via inductive heating device 4 pressed, whereby it is firmly clamped at its end in the bending arm 5.

Die Biegespannvorrichtung 6 ist in dem Biegearm 5 insgesamt verschiebbar angeordnet, so daß, wie Figur 3 zeigt, nach Vollendung des Biegevorganges eine Verschiebung der Spannvorrichtung 6 und damit eine Freigabe des Biegegutes erfolgt.The bending clamping device 6 can be displaced as a whole in the bending arm 5 arranged so that, as Figure 3 shows, a shift after completion of the bending process the clamping device 6 and thus a release of the material to be bent takes place.

Unmittelbar nach Verlassen des Rohrbogens der Biegevorrichtung lJird das nächste Rohr 1' in die Anlage gefahren.Immediately after leaving the pipe bend the bending device will be the next pipe 1 'is driven into the system.

Durch die erfindungsgemäße Spanneinrichtung wird die Biegemaschine ebenfalls vereinfacht, d.h. das bisher übliche Öffnen der Biegerollen und der Heizeinrichtung nach dem Biegevorgang kann entfallen, da das Rohr nunmehr in Längsachse weiter transportiert und die Fertigung optimal ablaufen kann' - Patent ansprüche -By means of the clamping device according to the invention, the bending machine also simplified, i.e. the previously usual opening of the bending rollers and the heating device after the bending process can be omitted, since the pipe is now transported further in the longitudinal axis and production can run optimally '- patent claims -
