Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum Biegen von rohr- oder stabförmigem Material gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a method and a device for bending tubular or rod-shaped material according to the preamble of
Gattungsgemäße Biegevorrichtungen zum Biegen von rohr- oder stabförmigem Material, insbesondere zum Biegen von Rohren, Drähten oder Profilen, sind aus dem Stand der Technik bekannt. Solche gebogenen Rohre werden beispielsweise in Solarkollektoren oder Wärmetauschern in Form von Wärmetauscherschlangen eingesetzt. Diese bestehen aus mäandernden Rohrleitungen, durch die ein Wärmeträgermedium gepumpt wird. Zur Herstellung solcher mäandernder Rohre, beispielsweise Kupferrohre, werden Biegemaschinen eingesetzt, welche das Rohrmaterial von einer Haspel über eine Richtstrecke ziehen. Anschließend wird das Rohr an einem Biegekopf entlang geschoben und schließlich an der gewünschten Stelle die Biegung durchgeführt. Dabei entsteht nach und nach ein mäanderndes Rohrgebilde. Da die Flächen solcher Kollektoren oder Wärmetauscher mitunter sehr groß sind, wird gerade bei den letzten Biegevorgängen zur Fertigstellung des mäandernden Rohrgebildes der bereits gebogene Teil des Rohrgebildes einer starken Belastung aufgrund der Bewegung des bereits gebogenen Teils des Rohrgebildes um den Biegepunkt ausgesetzt. Das mäandernde Rohrgebilde wird dabei sehr instabil.Generic bending devices for bending tubular or rod-shaped material, in particular for bending pipes, wires or profiles, are known from the prior art. Such curved tubes are used for example in solar collectors or heat exchangers in the form of heat exchanger coils. These consist of meandering pipes through which a heat transfer medium is pumped. For the production of such meandering pipes, such as copper pipes, bending machines are used, which pull the pipe material from a reel over a guideline. Subsequently, the tube is pushed along a bending head and finally carried out at the desired location, the bend. This gradually creates a meandering pipe structure. Since the surfaces of such collectors or heat exchangers are sometimes very large, just in the last bending operations to complete the meandering pipe structure of the already bent part of the pipe structure is exposed to a heavy load due to the movement of the already bent part of the pipe structure to the bending point. The meandering pipe structure becomes very unstable.
Um diesem Problem zu begegnen, sind an den herkömmlichen Biegemaschinen Tische zur Unterstützung des mäandernden Rohrgebildes angebracht.In order to counteract this problem, tables for supporting the meandering pipe structure are attached to the conventional bending machines.
Nachteilig ist, dass auch diese Tische zur Unterstützung des mäandernden Rohrgebildes bei einem Biegevorgang mit bewegt werden müssen. Diese Tische müssen ebenfalls mit Antrieben und entsprechenden Steuerungen sowie Führungen ausgerüstet sein. Der maschinenbautechnische Aufwand und damit auch die Kosten zur Herstellung und zum Betrieb einer solchen Biegemaschine sind dadurch bedingt sehr hoch.The disadvantage is that these tables must be moved to support the meandering tube structure in a bending operation with. These tables must also be equipped with drives and corresponding controls and guides. The mechanical engineering effort and thus the cost of producing and operating such a bending machine are conditionally very high.
Aufgabe der vorliegenden Erfindung ist es daher, die oben genannten Nachteile zu beseitigen und insbesondere eine Biegevorrichtung für rohr- oder stabförmigesObject of the present invention is therefore to eliminate the above-mentioned disadvantages and in particular a bending device for tubular or rod-shaped
Material bereitzustellen, welche auf solche mitbewegten Unterstützungstische verzichten kann.Provide material that can dispense with such mitbewegten support tables.
Diese Aufgabe wird durch eine Vorrichtung zum Biegen von rohr- oder stabförmigem Material mit den Merkmalen des Anspruchs 1 sowie ein Verfahren mit den Merkmalen des Anspruchs 15 gelöst.This object is achieved by a device for bending tubular or rod-shaped material having the features of
Erfindungsgemäß weist die Vorrichtung zum Biegen von rohr- oder stabförmigem Material eine Biegeeinheit mit mehreren, auf Führungsachsen geführten Biegeköpfen auf, die derart miteinander gekoppelt sind, dass mehrere Biegungen des rohr- oder stabförmigen Materials in einem Biegevorgang durchführbar sind. Durch die erfindungsgemäße Biegevorrichtung ist ermöglicht, dass bei einem Biegevorgang nicht jeweils nur eine Biegung des zu biegenden Materials erzeugt wird, sondern mehrere Biegungen gleichzeitig oder kurz nacheinander ausführbar sind.According to the invention, the device for bending tubular or rod-shaped material has a bending unit with a plurality of guided on guide axes bending heads, which are coupled together such that a plurality of bends of the tubular or rod-shaped material in a bending operation can be performed. The bending device according to the invention makes it possible that in a bending operation not only one bend of the material to be bent is generated in each case, but a plurality of bends can be executed simultaneously or in quick succession.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Biegeköpfe bestehen vorzugsweise aus einer Biegekontur und einer Biegerolle. Die Biegekonturen sind dabei derart senkrecht zur Biegerichtung drehbar an der Vorrichtung angeordnet, dass sie zwischen eine das rohr- oder stabförmige Material teilweise umgreifenden Position und einer das rohr- oder stabförmige Material freigebenden Position erstellbar sind. Dadurch ist ermöglicht, dass das zu biegende Material nach dem Biegevorgang in einfacher Weise freigegeben werden kann.The bending heads preferably consist of a bending contour and a bending roller. The bending contours are arranged so perpendicular to the bending direction rotatable on the device that they can be created between a tubular or rod-shaped material partially encompassing position and the tubular or rod-shaped material releasing position. This makes it possible that the material to be bent after the bending process can be released in a simple manner.
In einer Ausführungsvariante sind die Biegerollen drehbar an Koppelstangen angeordnet, wobei die Koppelstangen in einer nochmals bevorzugten Ausführungsvariante in ihrer Länge verstellbar ausgebildet sind. Mit solchen verstellbaren Koppelstangen ist es ermöglicht, das zu biegende Material beispielsweise zu Mäandern unterschiedlicher Länge zu biegen.In one embodiment, the bending rollers are rotatably arranged on coupling rods, wherein the coupling rods are formed adjustable in length in a further preferred embodiment variant. With such adjustable coupling rods, it is possible to bend the material to be bent, for example, to meanders of different lengths.
Die Erfindung betrifft ferner ein Verfahren zur Herstellung einer mäandernden Rohrleitung mit einer Vielzahl von Biegungen, wobei erfindungsgemäß eine Vielzahl von Biegungen gleichzeitig in einem Schritt hergestellt wird. Vorzugsweise werden dabei gleichzeitig vier Biegungen hergestellt. Hierdurch können mehrere Windungen gleichzeitig hergestellt werden und neben einer schnelleren Herstellungszeit auch eine exaktere Maßeinhaltung sichergestellt werden. Vorzugsweise werden die erzeugten Windungen dann um einen Betrag entsprechend der Länge des erzeugten Windungskörpers vorgeschoben und die nächsten Windungen in einem Schritt erzeugt.The invention further relates to a method for producing a meandering pipeline having a plurality of bends, wherein according to the invention a plurality of bends are produced simultaneously in one step. Preferably, four bends are produced simultaneously. This allows several turns produced at the same time and in addition to a faster production time and a more exact dimensional compliance can be ensured. Preferably, the generated windings are then advanced by an amount corresponding to the length of the generated winding body and the next windings are generated in one step.

Die Biegekonturen 8, 9, 10, 11 sind bevorzugt so ausgebildet, dass sie einen Biegeabschnitt mit einer umfangsseitigen Nut 19 aufweisen, welche das zu biegende rohr- oder stabförmige Material 20 während eines Biegevorgangs teilweise umgreift. Um das Material nach dem Biegevorgang wieder freigeben zu können, sind die Biegekonturen 8, 9, 10, 11 senkrecht zur Biegerichtung rotierbar an den Führungsachsen 4, 5, 6 angeordnet. Dadurch wird erreicht, dass das zu biegende Material 20 nach dem Biegevorgang durch Drehen der Biegekontur in eine bestimmte Winkelstellung, bei der die Biegekontur das Material nicht mehr umschließt, freigegeben und das fertig gebogene Material 20 für einen nächsten Biegevorgang vorgeschoben werden kann.The bending

In einer weiteren Variante ist die Länge der Koppelstangen 12, 13 veränderbar ausgeführt, beispielsweise durch ein in die Koppelstangen 12, 13 integriertes Schiebeelement. Dadurch kann die Länge der Koppelstangen 12, 13 während des Biegeprozesses verändert werden, so dass die Abstände der Führungsachsen 4, 5, 6 im Verhältnis zur Schlittenbewegung des Schlittens 7 unabhängig gesteuert werden können. Dadurch sind Variationen der Biegegeometrien, insbesondere Mäandergeometrien, ermöglicht.In a further variant, the length of the
