Rohrbiegedorn mit DrehantriebTube bending mandrel with rotary drive

Nach dem Patent Nr. 946 675 ist es bekannt, den Biegedorn einer Rohrbiegemaschine mit einer zum Fassen des Rohres dienenden Klemmvorrichtung und mit einem Längsantrieb zu versehen, damit der Dorn neben seiner Aufgabe, eine Verformung des Rohrquerschnittes im Biegebereich zu verhindern, auch ein Längsverschieben des Rohres, d. h. das Einziehen des zu biegenden Rohres in die Biegemaschine und das Herausschieben des gebogenen Rohres aus der Maschine, vornehmen kann.After the patent no. 946 675 it is known to the mandrel a Pipe bending machine to be provided with a clamping device serving to grasp the pipe and with a longitudinal drive so that the mandrel in addition to its task of preventing deformation of the pipe cross-section in the bending area, also longitudinal displacement of the pipe, d. H. pulling the pipe to be bent into the bending machine and pushing the bent pipe out of the machine, can make.

Wenn Rohrwerkstücke mit mehreren Biegungen versehen werden sollen, müssen die Rohrwerkstücke von Biegung zu Biegung jeweils in eine neue Lage gebracht werden. Dazu muß das Werkstück nicht nur, entsprechend den Abständen von Biegung zu Biegung, längsverschoben, sondern auch, entsprechend der Neigung der Biegungen zueinander, jeweils um seine Längsachse gedreht werden. Bei automatischen Rohrbiegemaschinen wird dieses Verschieben und Drehen des Rohrwerkstückes von Biegung zu Biegung in bekannter Weise durch ein längs- und drehend angetriebenes Außenspannfutter, in welches das in die Biegemaschine eingeführte Rohrende eingespannt ist, vorgenommen. Nach der Erfindung soll der ohnehin vorhandene Dorn anstelle des Spannfutters treten. Darin liegt der Vorteil, daß das Rohrwerkstück nicht nur ganz bis zum Ende gebogen, sondern hinterher auch ganz aus der Maschine herausgeschoben werden kann, was mit dem bekannten Außenspannfutter nicht möglich ist.If pipe workpieces are to be provided with several bends, the pipe workpieces must be brought into a new position from bend to bend. For this purpose, the workpiece not only has to be accordingly the distances from bend to bend, shifted lengthways, but also, according to the inclination of the bends to one another, each rotated about its longitudinal axis. With automatic tube bending machines, this shifting and turning of the tube workpiece from bend to bend in a known manner by means of a longitudinally and rotationally driven external chuck into which the inserted into the bending machine pipe end is made. According to the invention, the already existing mandrel is to be replaced of the chuck. This has the advantage that the pipe workpiece is not only bent all the way to the end, but also afterwards can also be pushed completely out of the machine, which is not possible with the known external chuck.

Erfindungsgemäß hat der Dorn, der, wie bekannt, mit einer Innenklemmvorrichtung zum Festhalten des Rohres und mit einem Längs-According to the invention, the mandrel, as is known, has an internal clamping device to hold the pipe in place and with a longitudinal

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Es zeigen:An exemplary embodiment is shown in the drawing. Show it:

Figur 2 den Dorn nach Figur 1 in kleinerem Maßstab mit aufgezogenem, gebogenem Rohr und zugehörigem Biegewerkzeug.Figure 2 shows the mandrel according to Figure 1 on a smaller scale with a raised, bent pipe and associated bending tool.

Der Dorn, bestehend aus der Dornstange 1 und dem starr mit dieser verbundenen Dornkopf 2, in dem die radial bewegbaren Spannbacken 3, \t die beim Vorschieben der Keilstange 4 den Dorn mit dem aufgeschobenem Rohrwerkstück kuppeln, eingebaut sind. Ein nicht gezeichneter Längsantrieb bewirkt dann das Verfahren des Domes mit dem Rohrwerkstück in der Längsrichtung. Der erfindungsgemäße Antrieb für die Drehung des Domes undThe mandrel consisting of the mandrel bar 1 and rigidly connected with this mandrel head 2, in which the radially movable clamping jaws 3, \ t which couple the mandrel with the deferred tube workpiece during advancement of the wedge rod 4 are built. A longitudinal drive (not shown) then moves the dome with the pipe workpiece in the longitudinal direction. The drive according to the invention for the rotation of the dome and
