Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung wendelförmiger Wellrohre, insbesondere aus längsnahtgeschweißten Metallrohren, wobei ein in einem rotationsbeweglich antreibbaren Wellerkopf drehbar gelagerter Wellerwälzring unter Einbringung der Wellung auf der Oberfläche eines glatten Rohres abwälzbar angeordnet ist, wobei die Vorrichtung mehrere in Fertigungsflussrichtung hinter dem Wellerkopf am Umfang des Wellrohres verteilt angeordnete Druckrollen aufweist, die gegen die sich gegenüberliegenden Flanken der Wellung des Wellrohres anlegbar sind, um beim Drehen um das Wellrohr den Abstand zwischen den Flanken zur Veränderung der Steigung zu reduzieren und/oder den Außendurchmessers des Wellrohres zu vergrößern.The invention relates to a device for producing helical corrugated pipes, in particular of longitudinally welded metal tubes, wherein a rotatably driven in a rotatable shaft head rotatably mounted Wellerwälzring is arranged abrollable by introducing the corrugation on the surface of a smooth tube, wherein the device more in the production flow direction behind the corrugated head on the circumference the corrugated pipe has arranged distributed pressure rollers which can be applied against the opposite flanks of the corrugation of the corrugated pipe to reduce the distance between the flanks to change the slope when turning around the corrugated pipe and / or to increase the outer diameter of the corrugated pipe.

In bekannten Vorrichtungen zur Herstellung von Wellrohren werden Formringe und Druckrollen verschiedener Art verwendet. Die DE 41 37 275 A1 betrifft ein Verfahren zur kontinuierlichen Herstellung schraubenlinienförmig oder ringförmig gewellter dünnwandiger, insbesondere längsnahtgeschweißter Metallrohre, bei welchen sich ein in einem drehantreibbaren Wellerkopf exzentrisch zum glatten Metallrohr frei drehbar gelagerter Wellerwälzring auf der Oberfläche des glatten Metallrohres unter Einbringung der Wellung abwälzt. Dabei wird das Metallrohr durch eine an dem glatten oder dem gewellten Metallrohr angreifende Abzugsvorrichtung transportiert. Die dabei auf den Wellerwälzring einwirkende Kraft wird ständig gemessen, um so die Drehgeschwindigkeit des Wellerkopfes in Abhängigkeit von der gemessenen Kraft zu regeln. Hierzu sind der Wellerwälzring und damit der Wellerkopf und mit diesem mechanisch verbundene Teile begrenzt längsaxial verschiebbar und wirken auf eine Kraftmessvorrichtung, insbesondere eine Kraftmessdose ein. Es wird eine festgelegte Kraft beziehungsweise ein festgelegter Druck am Wellerwälzring eingehalten, indem die Drehgeschwindigkeit des Wellerkopfes verändert wird. Dabei kann der Druck so eingestellt sein, dass der Wellerkopf je nach der gewünschten Wellung auf Zug, auf Druck oder in der neutralen Lage gefahren werden kann.Former rings and pressure rollers of various types are used in known devices for producing corrugated pipes. The DE 41 37 275 A1 relates to a method for the continuous production of helically or annularly corrugated thin-walled, in particular longitudinally welded metal tubes, in which a rotatably rotatable shaft head eccentrically to the smooth metal tube freely rotatably mounted Wellerwälzring rolls on the surface of the smooth metal tube with introduction of the corrugation. In this case, the metal tube is transported by an attacking on the smooth or corrugated metal tube extraction device. The force acting on the Wellerwälzring force is constantly measured so as to control the rotational speed of the shaft head in dependence on the measured force. For this purpose, the Wellerwälzring and thus the corrugator head and with this mechanically connected parts are limited longitudinal axis displaceable and act on a force measuring device, in particular a load cell. It is a specified force or a specified pressure on Wellerwälzring complied by the rotational speed of the shaft head is changed. In this case, the pressure can be set so that the corrugated head can be moved depending on the desired corrugation to train, to pressure or in the neutral position.

Aus der DE 66 09 600 U ist eine gattungsgemäße Vorrichtung zum Herstellen wendelförmig gewellter Metallschläuche oder dergleichen aus Metallrohren bekannt, die mehrere das Metallrohr einschließende und um das Metallrohr drehbare Formringe mit einer Schrägstellung gegenüber dem Metallrohr und einem gegenseitigen axialen Abstand aufweist, welcher einer vorgegebenen Wendelsteigung entspricht. Weiterhin hat die Vorrichtung mehrere in axialem Abstand von den Formringen und radial um das Metallrohr verteilte Druckrollen, deren Schrägstellung und axialer Abstand einer anderen vorgegebenen Wendelsteigung entspricht und deren gegenseitiger Abstand zunehmend geringer ist als die Wendelsteigung. Jede Druckrolle hat zwei seitliche Bereiche, die jeweils an den sich gegenüberliegenden Seitenwänden einer Welle angreifen und beim Drehen den Abstand zwischen den Seitenwänden zur Verringerung von Steigung und Erhöhung des Außendurchmessers der Wellung verändern. Der Abstand zwischen den Rädern der Druckrollen nimmt von der ersten bis zu der letzten Druckrolle in Rohr-Umfangsrichtung stetig ab.From the DE 66 09 600 U a generic device for producing helically corrugated metal tubes or the like of metal tubes is known, which has a plurality of the metal tube and rotatable around the metal tube forming rings with an inclination relative to the metal tube and a mutual axial distance corresponding to a predetermined helix pitch. Furthermore, the device has a plurality of axially spaced from the mold rings and radially around the metal tube pressure rollers whose inclination and axial distance corresponds to another predetermined helix pitch and the mutual distance is increasingly less than the helical pitch. Each pressure roller has two lateral areas which each engage the opposite side walls of a shaft and, when rotated, change the distance between the side walls to reduce pitch and increase the outer diameter of the corrugation. The distance between the wheels of the pressure rollers decreases steadily from the first to the last pressure roller in the tube circumferential direction.

Weiterhin ist auch durch die DE-AS 16 52 990 eine Lagerung des Wellerkopfes bekannt, die eine begrenzte Axialverschiebung des Wellerkopfes gestattet.Furthermore, by the DE-AS 16 52 990 a storage of the corrugated head is known, which allows a limited axial displacement of the corrugated head.

Ferner ist bei einem Verfahren gemäß der DE-AS 20 49 235 , bei dem die Wellung in der Rohrwandung durch ein sich auf das Glattrohr aufschraubendes Wellwerkzeug erzeugt wird, das Wellwerkzeug axial verschiebbar anzuordnen.Furthermore, in a method according to the DE-AS 20 49 235 in which the corrugation in the pipe wall is produced by a corrugated tool screwing onto the smooth pipe, the corrugated tool being arranged to be axially displaceable.

Die bekannten Vorrichtungen haben jedoch den Nachteil, nur unter großen Schwierigkeiten in derselben Vorrichtung Metallrohre verschiedener Größe und Art mit einer Wellung versehen zu können. Es ist ferner gelegentlich erwünscht, ein mit einer Wellung versehenes Metallrohr derart zu verändern, dass auf einer bestimmten Länge des Metallrohres eine größere Anzahl von Wellen vorhanden ist, um so die Steigung der Wellung zu vermindern, wobei jedoch die Form des Metallrohres aufrechterhalten werden soll.However, the known devices have the disadvantage that they can be provided with a corrugation only with great difficulty in the same device metal tubes of different sizes and types. It is also occasionally desirable to alter a corrugated metal tube such that there is a greater number of corrugations over a given length of the metal tube so as to reduce the pitch of the corrugation while maintaining the shape of the metal tube.

Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zur problemlosen Anpassung an nahezu beliebige Steigungen des einlaufenden Wellrohres zu schaffen.The invention has for its object to provide a way to easily adapt to almost any slope of the incoming corrugated pipe.

Diese Aufgabe wird erfindungsgemäß mit einer Vorrichtung gemäß den Merkmalen des Anspruchs 1 gelöst. Die weitere Ausgestaltung der Erfindung ist den Unteransprüchen zu entnehmen.This object is achieved with a device according to the features of claim 1. The further embodiment of the invention can be found in the dependent claims.

Erfindungsgemäß ist also eine Vorrichtung vorgesehen, bei der die Druckrollen in Bezug auf die Mittellängsachse des Wellrohres begrenzt axial beweglich angeordnet sind. Hierdurch wird in überraschend einfacher Weise eine nahezu unbegrenzte und selbsttätig wirksame Anpassung der Druckrollen an unterschiedliche, zuvor mittels des Wälzringes beziehungsweise der vorhergehenden Druckrolle eingebrachte Steigungen der Wellung ermöglicht, sodass insbesondere die individuelle Einstellung der Positionierung der Druckrollen entfällt. Dabei sind die Druckrollen derart in der Vorrichtung zu einer Baueinheit integriert, dass der Wälzring eine Vorwelleinrichtung bildet, während die Druckrollen die Nachwelleinrichtung bilden. Dadurch, dass nicht etwa der axiale Versatz der am Umfang verteilten Druckrollen die Steigung festlegt, sondern die Art der Vorwellung und die Geometrie der Druckrollen, kann eine Vielzahl unterschiedlicher Wellrohrsteigungen ohne Austausch der Druckrollen realisiert werden. Der Umformungsgrad kann dabei flexibel und in wirtschaftlich ebenso wie technologisch vorteilhafter Weise auf den Wälzring sowie auf die Druckrollen aufgeteilt werden, sodass in der Praxis eine wesentliche Entlastung des Wellkopfes erreicht werden kann. Hierbei wird außerdem eine unerwünschte Torsionsbeanspruchung des Wellrohres weitgehend vermieden.According to the invention, therefore, a device is provided in which the pressure rollers are arranged axially movable relative to the central longitudinal axis of the corrugated tube limited. As a result, a virtually unlimited and automatically effective adjustment of the pressure rollers to different, previously introduced by means of the Wälzringes or the previous pressure roller pitches of the corrugation is possible in a surprisingly simple manner, so that in particular the individual adjustment of the positioning of the pressure rollers deleted. In this case, the pressure rollers are integrated in the device into a structural unit such that the rolling ring forms a pre-shaft device, while the pressure rollers form the post-wave device. The fact that not about the axial offset of the circumferentially distributed pressure rollers determines the slope, but the type of Vorwellung and the geometry of the pressure rollers, a variety of different Wellrohrsteigungen can be realized without replacing the pressure rollers. The degree of deformation can be divided flexibly and economically as well as technologically advantageous manner on the Wälzring and on the pressure rollers, so that in practice a significant relief of the corrugated head can be achieved. In this case, an undesirable torsional stress of the corrugated pipe is also largely avoided.

Die Druckrollen könnten auf einer in Richtung der Mittellängsachse ausgerichteten Achse drehbeweglich und begrenzt axial verschiebbar angeordnet sein. Besonders vorteilhaft ist hingegen eine Ausführungsform der Erfindung, bei welcher die Druckrollen an einer um eine Achse schwenkbeweglichen Schwinge angeordnet sind, die auf der Achse durch einen Anschlag begrenzt verschiebbar angeordnet ist. Hierdurch wird in einfacher Weise eine radiale und axiale Verlagerung der Druckrollen mittels derselben Achse ermöglicht, sodass der Herstellungsaufwand minimiert werden kann. Zugleich kann die Schwinge mittels einer Vorspannkraft in Richtung des Wellrohres vorgespannt sein oder Stellglieder zur radialen Einstellung aufweisen. Weiterhin können in die Schwinge auch Sensoren zur Positionserfassung integriert sein.The pressure rollers could be arranged to be rotatable and limited axially displaceable on an axis aligned in the direction of the central longitudinal axis. In contrast, an embodiment of the invention is particularly advantageous in which the pressure rollers are arranged on a rocker which is pivotable about an axis and which is displaceably arranged on the axis so as to be displaceable by a stop. As a result, a radial and axial displacement of the pressure rollers is made possible by means of the same axis in a simple manner, so that the production cost can be minimized. At the same time, the rocker may be biased by a biasing force in the direction of the corrugated pipe or have actuators for radial adjustment. Furthermore, sensors for position detection can be integrated in the rocker.

Die Druckrollen könnten schräg anstellbar sein, um so beispielsweise durch den Neigungswinkel den Freiraum zwischen den randseitigen Bereichen der Rollen entsprechend dem Neigungswinkel zu verringern und somit eine Verstärkung der Umformung zu erreichen. Besonders vorteilhaft ist hingegen eine Abwandlung der Erfindung, bei welcher die Druckrollen um eine Längsachse im gewünschten Winkel zur Mittellängsachse des Wellrohres beweglich angeordnet sind, wobei die Steigung durch die Geometrie der zu diesem Zweck beispielsweise einstellbaren Druckrolle bestimmt ist.The pressure rollers could be obliquely adjustable, so as to reduce, for example, by the angle of inclination, the free space between the edge regions of the rollers according to the angle of inclination and thus to achieve an amplification of the deformation. In contrast, a modification of the invention is particularly advantageous in which the pressure rollers are movably arranged about a longitudinal axis at the desired angle to the central longitudinal axis of the corrugated tube, wherein the slope is determined by the geometry of the pressure roller, which is adjustable for this purpose, for example.

Eine andere, ebenfalls besonders sinnvolle Ausgestaltung der Erfindung wird dadurch erreicht, dass die Druckrollen an einem gemeinsamen Rollengestell angeordnet sind. Hierdurch können die Druckrollen zur Anpassung an wesentliche Dimensionsänderungen des Wellrohres gemeinsam ausgetauscht werden, sodass unerwünschte Stillstandszeiten der Vorrichtung verringert werden können. Dabei sind vorzugsweise alle Druckrollen an derselben Welle angeordnet.Another, also particularly useful embodiment of the invention is achieved in that the pressure rollers are arranged on a common roller frame. As a result, the pressure rollers can be exchanged to adapt to significant dimensional changes of the corrugated tube together, so that undesirable downtime of the device can be reduced. In this case, all pressure rollers are preferably arranged on the same shaft.

Dabei ist es besonders zweckmäßig, wenn das Rollengestell an der Vorrichtung in seiner axialen und/oder radialen Position einstellbar ist, sodass eine einfache Zentrierung der Druckrollen gegenüber dem Wellrohr ermöglicht wird. Dabei kann zudem zur Anpassung an unterschiedliche, mittels des Wälzringes eingebrachte Steigungen zusätzlich auch eine axiale Positionsänderung des Rollengestells vorgenommen werden.It is particularly expedient if the roller frame on the device in its axial and / or radial position is adjustable, so that a simple centering of the pressure rollers relative to the corrugated pipe is made possible. In addition, an axial position change of the roller frame can also be made to adapt to different, introduced by means of the Wälzringes gradients.

Weiterhin erweist es sich als besonders praxisnah, wenn die zumindest drei Druckrollen gleich verteilt an dem Umfang des Wellrohres angeordnet sind. Hierdurch wird eine gleichmäßige Verformungskraft in das Wellrohr eingeleitet, um so auch hohe Qualitätsanforderungen erfüllen zu können. Selbstverständlich ist die Vorrichtung nicht auf drei Druckrollen beschränkt. Vielmehr lässt sich je nach Einsatzzweck und Rohrdurchmesser mittels einer Mehrzahl von, beispielsweise sechs, Druckrollen eine weitere Qualitätsverbesserung erreichen, indem die je Druckrolle eingebrachten Verformungskräfte reduziert werden.Furthermore, it proves to be particularly practical if the at least three pressure rollers are distributed evenly distributed on the circumference of the corrugated tube. As a result, a uniform deformation force is introduced into the corrugated pipe in order to meet even high quality requirements. Of course, the device is not limited to three pressure rollers. Rather, depending on the application and pipe diameter by means of a plurality of, for example six, pressure rollers can achieve a further quality improvement by reducing the deformation forces introduced per pressure roller.

Eine andere, ebenfalls besonders Erfolg versprechende Ausgestaltung der Erfindung wird dann erreicht, wenn zumindest eine Druckrolle zwei seitliche, radial vorspringende Bereiche aufweist, die jeweils an den sich gegenüberliegenden Flanken der Wellung des Wellrohres anlegbar sind, um so eine durch die Geometrie und den Abstand der Bereiche bestimmte Verformung der Wellung zu erreichen. Der die Bereiche verbindende Zylinderkern ist dabei auch bei hohen Umformgraden stets zu dem Wellrohr beabstandet, um so einer Abflachung der Wellung vorzubeugen. Selbstverständlich können die Bereiche einteilig miteinander verbunden sein oder aber auf einem zylindrischen Körper beispielsweise auch austauschbar fixiert sein. Ferner können die vorspringenden Bereiche mit einer reibungsmindernden Oberflächenbeschaffenheit, insbesondere einer Beschichtung, ausgestattet sein, oder Einrichtungen zur Einstellung vorbestimmter Temperaturen aufweisen.Another, also particularly promising embodiment of the invention is achieved when at least one pressure roller has two lateral, radially projecting portions which can be applied to each of the opposite flanks of the corrugation of the corrugated tube, so as to a by the geometry and the distance Areas to achieve certain deformation of the corrugation. The cylinder core connecting the regions is always spaced even at high degrees of deformation to the corrugated pipe, so as to prevent a flattening of the corrugation. Of course, the areas can be integrally connected to each other or be fixed on a cylindrical body, for example, interchangeable. Further, the projecting portions may be provided with a friction-reducing surface finish, in particular a coating, or have means for setting predetermined temperatures.

Eine andere, ebenfalls besonders Erfolg versprechende Ausgestaltung der Erfindung liegt auch dann vor, wenn zumindest zwei paarweise angeordnete Druckrollen jeweils einen einzigen vorspringenden Bereich aufweisen und die Bereiche jeweils an den sich gegenüberliegenden Flanken der Wellung des Wellrohres anlegbar sind. Aufgrund der hierbei unabhängig voneinander beweglichen Druckrollen wird nahezu jede beliebige Kontur der Wellung, beispielsweise auch mit einer unterschiedlichen Neigung der vorder- und rückseitigen Flanken, realisierbar, sodass eine optimale Anpassung des Wellrohres an die jeweiligen Anforderungen erfüllt werden kann. Der Bereich besteht hierzu beispielsweise aus einem zylindrischen Vorsprung mit einem endseitigen Radius, wobei die Seitenflächen des vorspringenden Bereichs parallel zueinander verlaufen. Die mit dem einzigen vorspringenden Bereich ausgestatteten Druckrollen weisen dabei vorzugsweise eine konvexe Kontur auf.Another, also particularly promising embodiment of the invention is also present when at least two pressure rollers arranged in pairs each have a single projecting area and the areas each at the opposite flanks of the corrugation of the corrugated pipe can be applied. Due to the here independently movable pressure rollers almost any contour of the corrugation, for example, with a different inclination of the front and back flanks, realized, so that an optimal adaptation of the corrugated pipe can be met to the respective requirements. For this purpose, the region consists, for example, of a cylindrical projection with an end-side radius, the side surfaces of the projecting region extending parallel to one another. The pressure rollers equipped with the single projecting area preferably have a convex contour.

Dabei können diese mit dem einzigen vorspringenden Bereich ausgestatteten Druckrollen auf einer gemeinsamen Achse beweglich angeordnet sein. Besonders sinnvoll ist es hingegen, wenn die zwei Druckrollen jeweils um die zueinander und gegenüber der Mittellängsachse des Wellrohres geneigte Achse rotationsbeweglich angeordnet sind, wobei die Achsen derart zueinander geneigt sind, dass eine negative Steigung der Flanken der Wellung mittels der Druckrollen darstellbar ist. Dadurch wird erstmals eine auch als Toruswellung bezeichnete Verformung über die Vertikale hinaus ermöglicht, um so ein Höchstmaß an Flexibilität bei der Herstellung des Wellrohres zu ermöglichen. Die so geschaffene Wellung weist also im Bereich des Wellungsgrundes aufeinander zulaufende Flanken auf, sodass der Abstand der Flanken in radialer Richtung auf die Mittellängsachse abnimmt und im Bereich des Wellungsgrundes sein Minimum hat.In this case, these pressure rollers equipped with the single protruding area can be arranged movably on a common axis. It is particularly useful, however, when the two pressure rollers are rotatably arranged in each case about the mutually and with respect to the central longitudinal axis of the corrugated tube axis, wherein the axes are inclined to each other such that a negative slope of the flanks of the corrugation is represented by the pressure rollers. This allows for the first time also referred to as Toruswellung deformation beyond the vertical addition, so as to allow the highest degree of flexibility in the production of corrugated pipe. The corrugation created in this way therefore has mutually tapering flanks in the region of the corrugation base, so that the spacing of the flanks in the radial direction decreases towards the central longitudinal axis and has its minimum in the region of the corrugation bottom.

Zu diesem Zweck erweist sich eine Weiterbildung als besonders Erfolg versprechend, bei welcher die an den sich gegenüberliegenden Flanken der Wellung des Wellrohres anlegbaren Bereiche derselben Druckrolle oder unterschiedlicher Druckrollen in Richtung ihrer Achse zustellbar angeordnet sind, um so in Abhängigkeit des gewünschten Umformgrades den Abstand der beiden Bereiche, die jeweils an den sich gegenüberliegenden Flanken der Wellung des Wellrohres anlegbar sind, derselben Druckrolle oder benachbarter Druckrollen flexibel einstellen zu können. Insbesondere werden so Aufhärtungen im Wellungsgrund verringert. Die Zustellung ist dabei bei einer relativ zueinander geneigten Anordnung der Bereiche ebenso wie auch bei paralleler Anordnung realisierbar.For this purpose, a further development proves to be particularly successful, in which the regions of the same pressure roller or different pressure rollers which can be applied to the opposite flanks of the corrugated tube are arranged to be deliverable in the direction of their axis, thus depending on the desired degree of deformation the distance between the two Areas that can be applied in each case on the opposite flanks of the corrugation of the corrugated tube, to be able to flexibly adjust the same pressure roller or adjacent pressure rollers. In particular, so hardenings in Wellungsgrund be reduced. The delivery is feasible in a relatively inclined arrangement of the areas as well as in a parallel arrangement.

Dabei erweist es sich als besonders praxisnah, wenn diese Halbrollen mittels einer Einstellmutter in Achsrichtung zustellbar sind, sodass die Zustellung in einfacher Weise manuell durchgeführt werden kann. Zur Festlegung der eingestellten Position dient dabei eine Kontermutter.It proves to be particularly practical if these half rolls are deliverable by means of an adjusting nut in the axial direction, so that the delivery can be carried out manually in a simple manner. To determine the set position serves a lock nut.

Vorzugsweise sind die Geometrie und/oder der Abstand zwischen den Bereichen verschiedener Druckrollen unterschiedlich ausgeführt, um so in Drehrichtung des Rollengestells im Wellrohr einen steigenden Umformgrad sicherzustellen.Preferably, the geometry and / or the distance between the areas of different pressure rollers are designed differently, so as to ensure an increasing degree of deformation in the direction of rotation of the roller frame in the corrugated pipe.

The invention allows for various embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below.

In der Figur 1 sind drei am Umfang eines wendelförmigen Wellrohres 1 gleich verteilt angeordnete Druckrollen 2, 3, 4 dargestellt, die als zweite Umformstufe im Anschluss an eine mittels eines nicht gezeigten Wälzringes eingebrachte Wellung 5 einer weiteren Umformung mittels derselben, nicht weiter dargestellten Vorrichtung dient. Die Druckrollen 2, 3, 4 werden hierbei mit ihren seitlichen, radial vorspringenden Bereichen 2a, 2b, 3a, 3b, 4a, 4b jeweils an den sich gegenüberliegenden, in den Figuren 3 und 4 dargestellten Flanken 6, 7 der Wellung 5 abgewälzt, sodass sich bei der Drehbewegung um die Mittellängsachse 8 des Wellrohres 1 eine Veränderung von Steigung und Außendurchmesser der Wellung 5 ergibt.In the FIG. 1 are three on the circumference of a helical corrugated pipe 1 evenly distributed pressure rollers 2, 3, 4 shown, which serves as a second forming stage following a introduced by means of a rolling ring not shown corrugation 5 further forming by means of the same device, not shown. The pressure rollers 2, 3, 4 are in this case with their lateral, radially projecting portions 2 a, 2 b, 3 a, 3 b, 4 a, 4 b respectively at the opposite, in the Figures 3 and 4 shown flanks 6, 7 of the corrugation 5 rolled, so that during the rotation about the central longitudinal axis 8 of the corrugated pipe 1, a change of pitch and outer diameter of the corrugation 5 results.

Die Druckrollen 2, 3, 4 sind hierzu in einem in der Figur 2 gezeigten Rollengestell 9 angeordnet und können daher als eine gemeinsame Baueinheit in der Vorrichtung positioniert oder ausgetauscht werden. Zum Ausgleich der sich aufgrund der Umformung an jeder Druckrolle 2, 3, 4 ergebenden unterschiedlichen Steigung der Wellung 5 sind die Druckrollen 2, 3, 4 in Bezug auf die Mittellängsachse 8 des in der Figur 1 gezeigten Wellrohres 1 in Pfeilrichtung 10 begrenzt axial beweglich angeordnet. Hierzu sind die Druckrollen 2, 3, 4 jeweils an einer um eine Achse 11 schwenkbeweglichen Schwinge 12 angeordnet, wobei die Druckrollen 2, 3, 4 auf der Achse 23 begrenzt verschiebbar angeordnet sind.The pressure rollers 2, 3, 4 are for this purpose in a in the FIG. 2 arranged roller frame 9 and can therefore be positioned or replaced as a common structural unit in the device. To compensate for the resulting due to the deformation of each pressure roller 2, 3, 4 different pitch of the corrugation 5, the pressure rollers 2, 3, 4 with respect to the central longitudinal axis 8 in the FIG. 1 shown corrugated tube 1 in the direction of arrow 10 limited axially movable. For this purpose, the pressure rollers 2, 3, 4 are each arranged on a pivotable about an axis 11 rocker 12, wherein the pressure rollers 2, 3, 4 are arranged on the axis 23 slidably limited.

In der Figur 3 sind die unterschiedlichen Rollenprofile der in den Figuren 1 und 2 gezeigten Druckrollen 2, 3, 4 in einer Seitenansicht näher dargestellt. Um einen annährend übereinstimmenden Umformgrad des Wellrohres 1 durch jede einzelne Druckrolle 2, 3, 4 sicherzustellen, schließen die radial vorspringenden Bereiche 2a, 2b, 3a, 3b, 4a, 4b einen jeweils unterschiedlichen Winkel ein, der sich an den sich gegenüberliegenden Flanken 6, 7 der Wellung 5 des Wellrohres 1 abbildet. In der dargestellten Ausführungsform beträgt dieser mittels der Bereiche 2a, 2b, 3a, 3b der beiden in Drehrichtung aufeinanderfolgenden Druckrollen 2, 3 eingebrachte Flankenwinkel α circa 40° beziehungsweise der Flankenwinkel β circa 20°, während die letzte Druckrolle 4 parallele Bereiche 4a, 4b aufweist. Das auf diese Weise fertig gestellte Wellrohr 1 hat somit ebenfalls parallele Flanken 6, 7.In the FIG. 3 are the different role profiles in the FIGS. 1 and 2 shown pressure rollers 2, 3, 4 shown in more detail in a side view. In order to ensure an approximately matching degree of deformation of the corrugated tube 1 by each individual pressure roller 2, 3, 4, the radially projecting portions 2a, 2b, 3a, 3b, 4a, 4b include a different angle in each case, which at the opposite flanks 6, 7 of the corrugation 5 of the corrugated pipe 1 images. In the illustrated embodiment, this is by means of the regions 2a, 2b, 3a, 3b of the two successive in the direction of rotation pressure rollers 2, 3 introduced flank angle α about 40 ° or the flank angle β about 20 °, while the last pressure roller has 4 parallel portions 4a, 4b , The corrugated tube 1 finished in this way thus also has parallel flanks 6, 7.

Darüber hinaus ist auch eine weitergehende Umformung realisierbar, wie dies anhand der Figur 4 näher erläutert wird. Die in einer Seitenansicht gezeigten Druckrollen 13, 14 sind dabei um zueinander geneigte Achsen 15, 16 drehbeweglich. Die beiden Druckrollen 13, 14 haben jeweils einen einzigen vorspringenden Bereich 17, 18, die jeweils an den sich gegenüberliegenden Flanken 6, 7 der Wellung 5 des Wellrohres 1 anliegen, um so einen negativen Neigungswinkel γ der Flanken 6, 7 einzustellen. Zu diesem Zweck sind die Bereiche 17, 18 in Richtung ihrer jeweiligen Achse 15, 16 in Pfeilrichtung 19, 20 mittels einer Einstellmutter 21 zustellbar angeordnet und mittels einer Kontermutter 22 festlegbar. Hierdurch kann in einfacher Weise der Abstand a zwischen den Bereichen 17, 18 der benachbarten Druckrollen eingestellt und an die jeweiligen Anforderungen an die Flanken 6, 7 angepasst werden.In addition, a further transformation is feasible, as determined by the FIG. 4 is explained in more detail. The pressure rollers 13, 14 shown in a side view are rotatable about mutually inclined axes 15, 16. The two pressure rollers 13, 14 each have a single projecting portion 17, 18 which abut respectively on the opposite flanks 6, 7 of the corrugation 5 of the corrugated tube 1, so as to set a negative inclination angle γ of the flanks 6, 7. For this purpose, the areas 17, 18 in the direction of their respective axis 15, 16 in the direction of arrow 19, 20 arranged undeliverable by means of an adjusting nut 21 and by means of a lock nut 22 can be fixed. As a result, the distance a between the regions 17, 18 of the adjacent pressure rollers can be set in a simple manner and adapted to the respective requirements of the flanks 6, 7.
