Abstract
Description
Die Erfindung betrifft eine Rohrbiegemaschine mit einer um eine vertikale Achse drehbaren Biegeschablone, einem um die Achse der Biegeschablone schwenkbaren Schwenkarm, der eine Spannbacke zum Festspannen eines Rohrabschnitts an der Biegeschablone aufweist, und einer Gleitschiene, die ein Widerlager für den ungebogenen Rohrabschnitt aufweist.The invention relates to a pipe bending machine having a bending template that can be rotated about a vertical axis, a swivel arm that can be pivoted about the axis of the bending template, which has a clamping jaw for clamping a pipe section to the bending template, and a slide rail that has an abutment for the unbent pipe section.
Die bekannten Rohrbiegemaschinen haben eine drehbare Biegeschablone, die an ihrem Umfang eine Biegerille aufweist, die einen Teil des Querschnittes des zu biegenden Rohres aufnimmt. Das Rohr wird von einer an einem Schwenkarm befestigten Spannbacke in die Biegerohrrille gedrückt. Wird der Schwenkarm bei gleichzeitiger Drehung der Biegeschablone um die Achse der Biegeschablone herum verschwenkt, so wird das Rohr um die Biegeschablone herumgezogen, wobei eine Rohrbiegung erzeugt wird. Bei Rohren, die zunächst gerade sind, ist es gleichgültig, ob die Rohrbiegung nach rechts oder nach links erfolgt. Häufig kommt es jedoch vor, daß Rohre gegenläufig gebogen werden müssen, nämlich mit einer Rechtsbiegung und anschließend mit einer Linksbiegung. Diese Biegungen können unter Umständen sehr nahe aneinander liegen. In solchen Fällen kann, nachdem die erste Biegung hergestellt worden ist, das Rohr nicht gedreht werden, um die zweite Biegung zu erzeugen, weil eine solche Drehung durch die Teile der Biegemaschine verhindert wird.The known pipe bending machines have a rotatable bending template, which has a bending groove on its circumference, which receives part of the cross section of the pipe to be bent. The tube is pressed into the bending tube groove by a clamping jaw attached to a swivel arm. If the swivel arm is pivoted around the axis of the bending template while simultaneously rotating the bending template, the tube is pulled around the bending template, whereby a tube bend is generated. For pipes that are straight at first it doesn't matter whether the pipe bends to the right or to the left. However, it often happens that pipes have to be bent in opposite directions, namely with a right bend and then with a left bend. Under certain circumstances, these bends can be very close to each other. In such cases, after the first bend has been made, the tube cannot be rotated to produce the second bend because such rotation is prevented by the parts of the bending machine.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohrbiegemaschine zu schaffen, mit der auch komplizierte Rohrformen hergestellt werden können, bei denen Biegungen sehr nahe aneinander anschließen.The invention has for its object to provide a pipe bending machine with which complicated pipe shapes can be produced, in which bends are very close to each other.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Anspruch 1 angegebenen Merkmalen.This object is achieved according to the invention with the features specified in claim 1.
Bei der erfindungsgemäßen Rohrbiegemaschine kann der Schwenkarm um volle 180° verschwenkt werden und die Biegewerkzeuge sind derart ausgebildet, daß sie sowohl für Rechtsbiegen als auch für Linksbiegen geeignet sind. Demnach kann ein Rohr wahlweise von der linken oder der rechten Seite an die Biegeschablone angesetzt werden. Für Rechtsbiegung und für Linksbiegung ist jeweils eine separate Gleitschiene vorgesehen, die als Widerlager bzw. seitliche Abstützung für den nicht zu biegenden Rohrabschnitt dient. Ein Rohr kann mit der erfindungsgemäßen Rohrbiegemaschine sowohl mit einer Rechtsbiegung als auch mit einer Linksbiegung versehen werden, wobei es auch möglich ist, das Rohr zuvor um die Längsachse der Rohreinspanneinrichtung zu drehen. Wenn sich ergibt, daß ein bereits vorgebogenes Rohr bei Rechtsbiegung in eine Form gebracht wird, in der es mit Teilen der Rohrbiegemaschine kollidiert, kann das Rohr gegen die entgegengesetzte Seite der Biegeschablone gesetzt und in Linksbiegung verformt werden. Ferner besteht die Möglichkeit, Rechtsbiegungen und Linksbiegungen eines Rohres nacheinander vorzunehmen, ohne das Rohr verdrehen zu müssen.In the pipe bending machine according to the invention, the swivel arm can be swiveled through a full 180 ° and the bending tools are designed such that they are suitable for both right-hand and left-hand bending. Accordingly, a tube can be attached to the bending template from the left or the right side. A separate slide rail is provided for right-hand bends and left-hand bends, which serves as an abutment or lateral support for the pipe section that is not to be bent. With the pipe bending machine according to the invention, a pipe can be provided with both a right-hand bend and a left-hand bend, it also being possible to rotate the pipe beforehand about the longitudinal axis of the pipe clamping device. If it turns out that a pre-bent pipe at If the right bend is brought into a form in which it collides with parts of the pipe bending machine, the pipe can be placed against the opposite side of the bending template and deformed into a left bend. It is also possible to make right and left bends in succession without having to twist the tube.
Die Rohrbiegemaschine ermöglicht wegen der Wahl der Drehrichtung die Herstellung komplizierter Rohrformen mit einer einzigen Maschine oder auch die Weiterverarbeitung vorgebogener Rohre, die mit einer Maschine, die nur eine Biegerichtung aufweist, nicht gebogen werden könnten.Due to the choice of the direction of rotation, the tube bending machine enables the production of complicated tube shapes with a single machine or the further processing of pre-bent tubes that could not be bent with a machine that only has one bending direction.

Die Rohrbiegemaschine weist einen Biegekopf 10 auf, mit einem Arm 11, der von einer Stirnwand des Maschinengestells 12 horizontal absteht. Der Arm 11 kann an der Stirnwand des Maschinengestells 12 in horizontaler Richtung verfahren werden, wie durch den Pfeil 13 angedeutet ist, und außerdem in vertikaler Richtung.The pipe bending machine has a
Am vorderen Ende des Armes 11 befindet sich die Biegeschablone 14, die aus zwei übereinander angeordneten Schablonenteilen 15 und 16 besteht. Jedes Schablonenteil hat die Gestalt einer im wesentlichen zylindrischen dicken Scheibe, die an ihrem Umfang mit einer Biegerille 17 bzw. 18 versehen ist. Die Biegerille erstreckt sich jedoch nicht über den gesamten Umfang des Schablonenteils, sondern sie endet in einem tangentialen Klemmstück 19 bzw. 20.At the front end of the
Auf einem zur Biegeschablone 14 koaxialen Lager ist ein Schwenkarm 21 gelagert, der radial von der Biegeschablone absteht. An diesem Schwenkarm befindet sich die Spannbacke, die von einem (nicht dargestellten) Linearantrieb längs des Schwenkarms 21 bewegt werden kann. Die Spannbacke weist zwei Backenteile 23 und 24 auf, die nebeneinander, jedoch in unterschiedlichen Höhen angeordnet sind. Das untere Backenteil 23 befindet sich auf gleicher Höhe wie das untere Schablonenteil 15 und das obere Backenteil 24 befindet sich auf gleicher Höhe wie das obere Schablonenteil 16. Beide Backenteile werden gemeinsam vor- und zurückbewegt, jedoch ist es auch möglich, die Backenteile einzeln zu steuern. Da das Backenteil 24 mit dem Schablonenteil 16 kleineren Durchmessers zusammenwirkt, steht es in Richtung auf die Biegeschablone 14 weiter vor als das Backenteil 23. Jedes der Backenteile 23 und 24 weist eine Rille 25 bzw. 26 auf, die einen Teil des Umfangs des zu biegenden Rohres 27 umschließt, während ein anderer Teil des Umfangs in der entsprechenden Biegerille 17 bzw. 18 der Biegeschablone 14 liegt.A
Das Schablonenteil 15 ist für Rechtsdrehung (im Uhrzeigersinn) vorgesehen, d.h. von seinem Klemmstück 19 aus erstreckt sich die Biegerille 17 im Gegenuhrzeigersinn. Das Schablonenteil 16 ist dagegen für Linksdrehung vorgesehen, d.h. von seinem Klemmstück 20 aus erstreckt sich die Biegerille 18 im Uhrzeigersinn. Beide Klemmstücke 19 und 20 liegen auf derselben Seite eines Durchmessers 28 der Biegeschablone 14.The
Von dem Arm 11 stehen nach entgegengesetzten Seiten Gleitschienenträger 30 und 31 ab. Jeder Gleitschienenträger 30 trägt eine Gleitschiene 32 bzw. 33, die parallel zum Arm 11 verläuft und dazu dient, die beim Rohrbiegen erzeugte Gegenkraft des Rohres aufzunehmen und das Rohr 27 seitlich abzustützen. Die Gleitschienen sind jeweils durch eine Antriebsvorrichtung längs ihres Gleitschienenträgers 30,31 verfahrbar. Die Gleitschiene 32 ist wirksam, wenn das Backenteil 23 zum Einsatz kommt. Sie befindet sich demnach auf gleicher Höhe wie das Backenteil 23 und das Schablonenteil 15. Die Gleitschiene 33 ist demgegenüber höher angeordnet. Sie kommt zum Einsatz, wenn das Rohr 27 an die entgegengesetzte Seite der Biegeschablone angesetzt wird und das Backenteil 24 zum Einsatz kommt.Slide arm supports 30 and 31 protrude from the
Jede der Gleitschienen 32 und 33 ist ferner mit einem Längsantrieb versehen, um dem Rohr während des Biegevorganges nachfolgen zu können.Each of the
In der in den durchgezogenen Linien dargestellten Position des Schwenkarms 21 ist die Spannbacke 22 quer zum Arm 11 und zur Richtung des Rohres 27 ausgerichtet und sie befindet sich auf der linken Seite der Biegeschablone 14. Das untere Backenteil 23 ist auf der linken Seite des Durchmessers 28 angeordnet und das Backenteil 24 auf der rechten Seite. Wird die Spannbacke 22 vorgeschoben, wird das Rohr zwischen dem Backenteil 23 und dem Klemmteil 19 festgeklemmt. Durch Drehen der Biegeschablone 14 erfolgt die Herstellung einer Rechtsbiegung des Rohres 27. Dabei befindet sich die untere Gleitschiene 32 in der Vorschubstellung, so daß sie das Rohr abstützt und die Gegenkraft aufnimmt. Ein Teil der Gleitschiene 32 ragt unter das Backenteil 24, um in der Nähe des Durchmessers 28 ebenfalls noch eine Abstützung zu bewirken.In the position of the
Wenn eine Linksbiegung erfolgen soll, wird das Rohr 27 an die entgegengesetzte Seite der Biegeschablone angesetzt, und zwar in Höhe des oberen Schablonenteils 16. Der Schwenkarm 21 befindet sich dann in der um 180° verschwenkten Position 21a. Das untere Backenteil 23, das nicht benutzt wird, ragt unter das vordere Ende der Gleitschiene 33. Wird die Spannbacke 22 vorgeschoben, so drückt das obere Backenteil 24 das Rohr gegen das obere Schablonenteil 16. Die obere Gleitschiene 33 wird vorgeschoben, um das Rohr seitlich abzustützen. Dann erfolgt aus der Position 21a des Schwenkarms eine Linksdrehung, wobei ein Abschnitt des Rohres um das Schablonenteil 16 herumgezogen und somit gebogen wird.If a left-hand bend is to take place, the
