Description

Die Erfindung betrifft eine Rohrbiegevorrichtung gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a pipe bending device according to the preamble of the patent claim.

Eine derartige Rohrbiegevorrichtung ist aus der DE-OS 21 12 019 bekannt.Such a pipe bending device is known from DE-OS 21 12 019.

Das Lösen des gebogenen Rohrs, d. h. des Rohrbogens am Ende des Biegevorganges ist häufig umständlich und zeitaufwendig.Loosening the bent tube, d. H. the pipe bend at the end of the bending process is often cumbersome and time consuming.

Aufgabe der Erfindung ist es daher, die eingangs genannte Rohrbiegevorrichtung so auszubilden, daß das Lösen des Rohrbogenanfanges bzw. des vorderen Rohrendes an der Spanneinrichtung schnell und einfach erfolgen kann.The object of the invention is therefore to design the pipe bending device mentioned above so that the Loosen the beginning of the pipe bend or the front end of the pipe on the clamping device quickly and easily can be done.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Patentanspruchs angegebenen Merkmale.This object is achieved according to the invention by what is specified in the characterizing part of the patent claim Characteristics.

Durch die erfindungsgemäß ausgebildete Spanneinrichtung 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 tensioning device designed according to the invention enables the sheet to be released more quickly achieved so that the finished pipe bend moved out of the bending device without further measures and the next pipe can be moved into the bending device.

Die bisher erforderlichen Nebenzeiten werden durch die erfindungsgemäße Vorrichtung erheblich verkürzt.The previously required non-productive times are considerably shortened by the device according to the invention.

Die erfindungsgemäße Vorrichtung kann dabei eine Außen- und/oder Innenspanneinrichtung aufweisen und ist für jeden Biegewinkel geeignetThe device according to the invention can have an external and / or internal clamping device and is suitable for every bending angle

In der ein Ausführungsbeispiel der Erfindung zeigenden Zeichnung sind die verschiedenen Vorgänge beim Biegen eines Rohres schematisch dargestellt. Es zeigtIn the drawing showing an embodiment of the invention are the various operations shown schematically when bending a pipe. It shows

F i g. 1 eine Rohrbiegevorrichtung vor dem Biegevorgang,
F i g. 2 die Vorrichtung nach dem Biegevorgang,F i g. 1 a pipe bending device before the bending process,
F i g. 2 the device after the bending process,

Fig. 3 die Vorrichtung mit dem freigegebenen Biegegut.3 shows the device with the released material to be bent.

In den Darstellungen der F i g. 1 und 2 wird das Rohr 1 mit Hilfe einer Deckeinrichtung 2 durch Biegerollen 3 d. h. mit Hilfe einer Einrichtung zum Verschieben und Führen über eine induktive Heizeinrichtung 4 gedrückt, wobei es an seinem Ende fest in den Biegearm 5 eingespannt ist.In the representations of FIG. 1 and 2 become pipe 1 with the help of a deck device 2 by bending rollers 3 d. H. with the help of a device for moving and Guide pressed over an inductive heating device 4, whereby it is firmly in the bending arm 5 at its end is clamped.

Die Spanneinrichtung 6 ist in dem Biegearm 5 insgesamt verschiebbar angeordnet, so daß, wie F i g. 3 zeigt, nach Vollendung des Biegevorganges eine Verschiebung dir Spannvorrichtung 6 und damit eine Freigabe des Biegegutes erfolgt. Unmittelbar nach dem der Rohrbogen die Biegevorrichtung verlassen hat, wird das nächste Rohr Γ eingefahren.The clamping device 6 is arranged in the bending arm 5 so that it can be displaced as a whole, so that, as in FIG. 3 shows, after completion of the bending process, a shift dir jig 6 and thus a The bending material is released. Immediately after the pipe bend has left the bending device retracted the next pipe Γ.

Durch die Verschiebbarkeit der SpanneinrichtungDue to the displaceability of the clamping device

kann das bisher übliche Öffnen der Biegerollen und der Heizeinrichtung nach dem Biegevorgang entfallen, da das Rohr nunmehr in Längsachse weiter transportiert und die Fertigung optimal ablaufen kann.the previously usual opening of the bending rollers and the heating device after the bending process can be dispensed with, since the pipe is now transported further in the longitudinal axis and production can proceed optimally.
