Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur Herstellung von U-förmig gebogenen Rohren, welche als Steigbügel in Kanalisationen, Schächten, Stauwehren, Reservoiren, aber auch in Kaminen und Türmen aller Art, inner- und außerhalb derselben verwendbar sind.The present invention relates to a device for manufacturing U-shaped bent Pipes, which are used as stirrups in sewers, shafts, weirs, reservoirs, but also in Fireplaces and towers of all kinds, inside and outside the same, can be used.
Das zur Herstellung eines Steigbügels geeignete Rohrstück weist einen Kunststoffschlauch, vorzugsweise auf Polyäthylenbasis auf, welcher in kaltem Zustand lose auf das Rohrstück aufgesteckt und anschließend durch Streckung zum Haften gebracht wird. Dabei erfolgt die Streckung des Schlauches mit der Biegung des Rohrstückes in die gewünschte Form.The pipe section suitable for producing a stirrup has a plastic tube, preferably based on polyethylene, which is loosely attached to the pipe section when cold and then is made to adhere by stretching. The hose is stretched with the Bending the pipe section into the desired shape.
Die vorgeschlagene Vorrichtung zur Herstellung von U-förmig gebogenen Rohren ist dadurch gekennzeichnet, daß sie ein Auflagestück mit Klemmklotz und mit Formrollen zusammenwirkende, an der Biegekante dem Biegeradius entsprechende Rundungen aufweisende Formklötze besitzt, die beidseitig des Auflagestückes angeordnet sind und daß die ao Formrollen und Formklötze gegenüber dem Auflagestück und Klemmklotz dem zu biegenden Rohr entlang bewegbar sind.The proposed device for the production of U-shaped bent tubes is characterized in that that they have a support piece with clamping block and cooperating with form rollers on the The bending edge has shaped blocks that correspond to the bending radius and have shaped blocks on both sides of the support piece are arranged and that the ao form rollers and mold blocks opposite the support piece and clamping blocks are movable along the pipe to be bent.
In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigtThe drawing shows an example of an embodiment of the subject matter of the invention, namely shows

Zur Herstellung eines Steigbügels wird ein Stahlrohrl verwendet, welches auf die fertige Länge des Steigbügels abgeschnitten wird. Die Stahlrohrenden werden zu Mauerankern geformt.To make a stirrup, a steel tube used, which is cut to the finished length of the stapes. The steel pipe ends are formed into wall anchors.
Über das Stahlrohr wird ein Polyäthylenschlauch 3 gezogen, und zwar in kaltem Zustand lose aufgesteckt. Anschließend wird der Schlauch durch Streckung zum Haften gebracht. Die Streckung des Schlauches erfolgt durch die Biegung des Stahlrohres in die gewünschte Form.A polyethylene hose 3 is pulled over the steel tube, loosely attached when it is cold. The tube is then made to adhere by stretching. The stretching of the Hose is made by bending the steel tube into the desired shape.
Der Biegevorgang ist aus den F i g. 2 bis 6 ersiehtlieh.
Das ummantelte Rohr 5 wird mittels einer Biegevorrichtung gebogen, welche Biegevorrichtung ein
Auflagestück 6 mit radial zum Rohrstück beweglichem Klemmklotz 7 aufweist. Die Betätigung des
Klemmklotzes 7 kann mechanisch, hydraulisch oder pneumatisch erfolgen. An beiden Seiten des Auflagestückes
6 sind in der Längsrichtung des Rohres 5 Vorrichtung zur Herstellung von U-förmig
gebogenen RohrenThe bending process is shown in FIGS. 2 to 6 can be seen. The jacketed pipe 5 is bent by means of a bending device, which bending device has a support piece 6 with a clamping block 7 which can be moved radially to the pipe piece. The clamping block 7 can be actuated mechanically, hydraulically or pneumatically. On both sides of the support piece 6 are in the longitudinal direction of the tube 5 device for producing U-shaped
bent pipes

beweglich gehaltene Formelemente 8 vorgesehen, mit welchen Formrollen 9 zusammenwirken. Zum Biegen des Rohres 5 wird zunächst dasselbe mittels des Klemmklotzes 7 am Auflagestück 6 festgehalten, worauf die Formrollen 9 leicht angepreßt und den Radien der Formelemente 8 entsprechend bewegt werden. Dadurch wird sowohl das Stahlrohr gebogen als auch die Kunststoffhülle gestreckt. Durch diese Streckung wird die Kunststoffhülle am Rohrstück zum Haften gebracht.movably held mold elements 8 are provided, with which mold rollers 9 cooperate. To bend the pipe 5, the same is first held by means of the clamping block 7 on the support piece 6 , whereupon the forming rollers 9 are pressed lightly and the radii of the forming elements 8 are moved accordingly. This will both bend the steel pipe and stretch the plastic shell. This stretching causes the plastic sleeve to adhere to the pipe section.
Wie aus den F i g. 3 und 4 ersichtlich ist, wird das Rohrstück etwas mehr als der gewünschte Winkel gebogen, damit beim Zurückfedern das Stahlrohr die vorgesehene Form annimmt. Um das Herausnehmen des fertigen Bügels zu erleichtern bzw. zu ermöglichen, werden die Formelemente 8 nach beendigter Biegung in den Pfeilrichtungen 10 bewegt, so daß sie die aus der F i g. 4 ersichtliche Lage einnehmen. Gleichzeitig werden die Formrollen 9 und der Klemmklotz 7 in der Pfeilrichtung 11 vom Rohrstück abgehoben.As shown in FIGS. 3 and 4 can be seen, the pipe section will be slightly more than the desired angle bent so that the steel tube takes on the intended shape when it springs back. To take out To facilitate or enable the finished bracket, the form elements 8 are completed after Bend moved in the directions of arrows 10, so that they are from the F i g. 4 Assume the obvious position. At the same time, the forming rollers 9 and the clamping block 7 are removed from the pipe section in the direction of the arrow 11 picked up.
In den F i g. 5, 6 und 7 ist eine Formrolle näher gezeigt. Aus diesen Figuren ist ersichtlich, daß die Formrolle 9 den elastisch verformbaren Polyäthylenschlauch 3 des Rohres 1 streckt und dabei einen Wulst 12 erzeugt. Um diesen Effekt zu verstärken, ist die Formrolle 9 mit einer Bremstrommel 13 versehen, gegen welche Bremsklötze 14 angepreßt werden können.In the F i g. 5, 6 and 7 a forming roller is shown in more detail. From these figures it can be seen that the Form roller 9 stretches the elastically deformable polyethylene tube 3 of the tube 1 and thereby a Bead 12 generated. To increase this effect, the forming roller 9 is provided with a brake drum 13, against which brake pads 14 can be pressed.
