Der Gegenstand des Anspruchs 3 des Patentes 1011843 wird durch die Erfindung in vorteilhafter Weise weiter ausgestaltet, indem eine einfache Verstellmöglichkeit für die Biegerollen angegeben wird, die dazu geeignet ist, die Stellung der Biegerollen den jeweiligen Erfordernissen des Biegevorganges anzupassen und insbesondere das Biegen von sich kegelförmig im Querschnitt verjüngenden Rohren in weitgehend selbsttätiger Weise zu ermöglichen.The subject matter of claim 3 of patent 1011843 is made more advantageous by the invention Way further developed by providing a simple adjustment option for the bending rollers which is suitable for adjusting the position of the bending rollers to the respective requirements of the bending process adapt and in particular the bending of conically tapering tubes in cross section to enable in a largely automatic manner.
Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß die Radialverstellung der in .ihren Gerüsten radial verschieblich gelagerten Rollenträger unter Zwischenschaltung von Kurventrieben mittels auf jedem Gerüst um die Längsachse der Maschine drehbar gelagerter Stellringe erfolgt, die durch mit jedem der Ringe kämmende sowie mit zwei mit verschiedenem Drehsinn umlaufenden Wellen kuppelbare Ritzel drehantreibbar sind.According to the invention, this aim is achieved in that the radial adjustment of the scaffolding radially displaceable roller carrier with the interposition of cam drives by means of Each frame around the longitudinal axis of the machine is rotatably mounted adjusting rings, which through with each the rings meshing and can be coupled with two rotating shafts with different directions of rotation are rotatable.
Die Zeichnung veranschaulicht die Erfindung an Hand von Ausführungsbeispielen; es zeigtThe drawing illustrates the invention on the basis of exemplary embodiments; it shows
Fig. 1 einen Schnitt durch eine Ausführungsform der Biegerollen-Verstellvorrichtung,1 shows a section through an embodiment of the bending roller adjusting device,
Fig. 2 einen Schnitt längs der Linie A-A in Fig. 1,FIG. 2 shows a section along the line AA in FIG. 1,
Fig. 3 einen Schnitt durch eine andere Ausführungsform der Biegerollen-Verstellvorrichtung. 3 shows a section through another embodiment of the bending roller adjusting device.
Die radiale Verstellung der in den Gerüsten 13 angeordneten Rollen 11, die für die Herstellung von Rohren mit zusammenlaufenden, auseinanderlaufenden, parallelen, beliebig gebogenen oder dergleichen Erzeugenden erforderlich ist, wird gemäß Fig. 1 durch Schraubenbolzen 1 und Muttern mit hoher Gewindesteigung bewirkt, womit das Lager 22 jeder Rolle 11 versehen ist. Die Schraubenbolzen 1 tragen, auf ihnen befestigt, ein Ritzel 2 (kegelförmig bzw. zylindrisch mit geraden oder schraubenförmigen Zähnen), das in einen entsprechend verzahnten Ringsektor 3 eingreift, der um die Längsachse der Maschine drehbar gelagert ist. Dieser Ringsektor kann auch abwechslungsweise von zwei Stirnrädern 4 getrieben werden, die in einen verzahnten Bogensektor9 eingreifen und die über Kupplungen 5 wahlweise in entgegengesetzten Richtungen angetrieben werden, deren Antrieb ihrerseits zweckmäßig durch zwei in entgegengesetzten Drehrichtungen umlaufende Übertragungswellen 6 erfolgt.The radial adjustment of the rollers 11 arranged in the stands 13, which are used for the production of Pipes with converging, diverging, parallel, arbitrarily curved or the like Generating is required, is shown in FIG. 1 by bolts 1 and nuts with high Causes the thread pitch, with which the bearing 22 of each roller 11 is provided. Carry the bolts 1, attached to them, a pinion 2 (conical or cylindrical with straight or helical teeth), which engages in a correspondingly toothed ring sector 3 around the longitudinal axis of the machine is rotatably mounted. This ring sector can also be driven alternately by two spur gears 4 which engage in a toothed arc sector9 and which are optionally in opposite directions are driven, their drive in turn expediently by two in opposite directions of rotation rotating transmission shafts 6 takes place.
Die radiale \rerstellung der Rollen kann auch durch entsprechend gestaltete Steuerscheiben (Fig. 3) herbeigeführt werden. In dem Ring 2O1 der offen oder geschlossen in entsprechenden Führungen mit geschmierten reibungsarmen Flächen bzw. in Rollen verdreht werden oder durch ein anderes System, das die Reibung zwischen den Teilen auf einen Mindestwert herabdrückt, gelagert sein kann, sind Führungsschlitze 19 von entsprechender Form eingebettet, von The radial \ r creation of the rollers can also be appropriately designed control disks (Fig. 3) are brought about. In the ring 2O 1, which can be rotated open or closed in appropriate guides with lubricated low-friction surfaces or in rollers or by another system that reduces the friction between the parts to a minimum value, guide slots 19 of a corresponding shape are embedded , from

denen Rollen 21 geführt werden, die über ein Lager, das gabelartig oder auch frei tragend sein kann, an den Lagerstücken 22 der Rollen 11 befestigt sind.which rollers 21 are guided, which have a bearing that can be fork-like or cantilevered the bearing pieces 22 of the rollers 11 are attached.
Jede Rollengruppe ist mit einem derartigen Steuerring ausgerüstet. Sein Antrieb erfolgt durch die gleichen Vorrichtungen, wie sie in dem Antriebssystem für die radiale Verstellung der Rollen mittels verzahnter Räder und Zahnkränzen Anwendung finden.Each roller group is equipped with such a control ring equipped. It is driven by the same devices as in the drive system are used for the radial adjustment of the rollers by means of toothed wheels and sprockets.
Auf diese Weise wird erreicht, daß durch Verdrehen der Ringe die Schlitzführungen, innerhalb deren die kleinen Rollen 21 geführt sind, auf diese einwirken und damit die Biegerollen 11 radial verstellt werden.In this way it is achieved that by turning the rings, the slot guides within which the small rollers 21 are guided, act on them and thus the bending rollers 11 are adjusted radially.
Die Ausbildung der Schlitze ist eine derartige, daß es bei einer fortlaufenden Verdrehung der Ringe möglich ist, Rohre von einer bestimmten Beschaffenheit zu erzeugen.The formation of the slots is such that there is a continuous rotation of the rings it is possible to produce pipes of a certain quality.

und/oder durch passende innere und äußere Profilierung der Ringe gewährleistet werden.and / or can be ensured by suitable inner and outer profiling of the rings.
Jeder Ring kann in einem oder in mehreren Punkten in beliebiger Weise angetrieben werden.Each ring can be driven in any way in one or more points.
Die Betätigung der Kupplungen, durch die der Antrieb und die Stillsetzung der Rollenverstellung gesteuert wird, erfolgt durch einen Hebel 7 mittels einer Reihe von verzahnten Sektoren 8, die im Bedarfsfall über Schwinghebel 8' von einer Förderkette 10 mit Nasen 10' für das Blech angetrieben werden. Der Antrieb der beiden Übertragungswellen äst von der Welle abgenommen, die die Zahnräder trägt, welche die Ketten über zwecks Geschwindigkeitsänderung auswechselbare Zahnräder antreiben. Auf diese Weise ist es möglich, die Umdrehungszahlen der einen Rädergruppe im Verhältnis zu der der anderen Zahnrädergruppe sowie der beiden Übertragungswellen zu verändern, genau wie es beispielsweise bei Drehbänken zur Änderung der Schraubengänge üblich ist. Eine solche Möglichkeit, die Umdrehungszahlen verändern zu können, erlaubt, die radiale Verstellung der Biegerohre zu variieren, womit die Bewegungen der Rollen in bezug auf die Durchgangsgeschwindigkeit des Bleches abgestimmt und somit alle möglichen Kegelformen innerhalb der Bearbeitungsgrenzen der in Frage stehenden Maschine hergestellt werden können.The actuation of the clutches, through which the drive and the shutdown of the roller adjustment are controlled is done by a lever 7 by means of a series of toothed sectors 8, which if necessary are driven via rocker arm 8 'from a conveyor chain 10 with lugs 10' for the sheet metal. Of the Drive of the two transmission shafts is removed from the shaft that carries the gears, which Drive the chains via interchangeable sprockets to change the speed. In this way it is possible to determine the number of revolutions of one gear group in relation to that of the other gear group as well as the two transmission shafts, just as it is, for example, with lathes to change the screw threads is common. One such way to change the number of revolutions being able to vary the radial adjustment of the bending tubes, thus making the movements of the rollers in relation to the speed of passage of the sheet and thus all possible Taper shapes are made within the machining limits of the machine in question can.
