  Vorrichtung zur Herstellung von Profilen durch Verformung von Metallstreifen   oder-stäben durch  
Ziehen zwischen Formwalzen.

 annähernd senkrecht zueinander. Die   Wirkungsriehtung   der einen Gruppe des Formwalzensystems verläuft dabei wieder annähernd parallel zur Wirkungsrichtung der   Zuführungs- bzw.   Abführungs- rollen. Die Formwalzen lagern in Bügeln, die im Formwalzengehäuse mittels Schraubenspindeln ein- und feststellbar sind. 



   Beim Ausführungsbeispiel nach Fig. 3 trägt der   Formwalzenständer   23 drei, je aus einer Druckund einer Gegenwalze bestehende Walzengruppen. Diese Walzengruppen sind in einem Rahmen 22 gelagert, der im Formwalzenständer 23 verdrehbar ist. Mittels der Fixierleisten 24 und 25 kann der
Rahmen 22 in jede erforderliche Lage gebracht werden, so dass die Verfolmungswalzen auch in ihrer
Gesamtheit in bezug auf das zu verformende Material beliebig verdreht und eingestellt werden können. 



  Ausser dieser Einstellung der Formwalzen ist wieder eine Einzeleinstellung der in   Druckbügeln   lagernden Formwalzen mittels Schraubenspindeln gegeben. Bei der Herstellung komplizierterer Profile sind zwischen den Einführungs- und Abführungsrollen zweckmässig mehrere Walzengruppen angeordnet, die in der   Förderrichtung   des zu verformenden Materials hintereinanderliegen. Die eigentliche Ver-   formarbeit kann   hier vorteilhafteiweise in eine Vorformung und eine   Fertigformung   aufgeteilt werden, wobei auch noch mehrere Zwischenverformungen eingeschaltet werden können. Auch hier wird das Profil in einem einzigen Arbeitsgange, d. h. einem Durchgange durch das Formwalzensystem, jedoch an mehreren räumlich hintereinanderliegenden Stellen der Verformung unterzogen.

   Das Formwalzensystem kann hier eine den   Zuführungsrollen nachgelagerte Vorformungsgruppe   aufweisen, deren Wirkungsrichtung wieder annähernd parallel zu jener der Zuführungsrollen verläuft und an welche eine Fertigformungsgruppe   anschliesst,   welche Formwalzen mit zueinander im Winkel verlaufenden Wirkungsrichtungen aufweist. 



   Durch die universelle Verstellbarkeit der Zuführungs- und Abführungsrollen. der Walzen des Formwalzensystems sowie durch die gesamte Verstellbarkeit dieser Teile mittels der verschwenkbaren Platte 1 ist vollkommen geradliniger und streng ausgerichteter Durchzug des Materials und gleichmässiges Anliegen desselben an die die   Formarbdt   vollführenden Walzen gewährleistet.   Hicdurch   wird auch bei Verwendung von Walzengruppen mit zueinander im Winkel   verlaufenden Wirkungsriehtungen ein   gleichmässiges Anliegen sämtlicher Walzen an das Material und damit eine gleichmässige Bearbeitung desselben über sämtliche zu verformende Flächen erzielt und die Gefahr beseitigt, dass der auf das Material auszuübende Druck bzw.

   Gegendruck durch die   Zufuhrung-odeur   Abführungsrollen aufgenommen wird, so dass die durch diese   unerwünschte   Entlastung betroffene Formwalze nicht voll wirken kann. Durch die Vermeidung dieser   i'belstände   werden gemäss der Erfindung auch sehr komplizierte Profile mit grösster Genauigkeit erhalten. 



   PATENT-ANSPRUCHE :

 approximately perpendicular to each other. The direction of action of one group of the forming roller system again runs approximately parallel to the direction of action of the feed and discharge rollers. The forming rollers are stored in brackets that can be adjusted and locked in the forming roller housing by means of screw spindles.



   In the embodiment according to FIG. 3, the forming roll stand 23 carries three groups of rolls, each consisting of a pressure roll and a counter roll. These roller groups are mounted in a frame 22 which can be rotated in the forming roller stand 23. By means of the fixing strips 24 and 25, the
Frame 22 can be brought into any required position so that the tracking rollers are also in their
The whole can be rotated and adjusted as desired with respect to the material to be deformed.



  In addition to this setting of the forming rollers, there is again an individual setting of the forming rollers mounted in pressure brackets by means of screw spindles. When producing more complicated profiles, several groups of rollers are expediently arranged between the infeed and outfeed rollers, which roller groups lie one behind the other in the conveying direction of the material to be deformed. The actual deformation work can here advantageously be divided into a pre-forming and a final forming, with several intermediate deformations also being able to be switched on. Here, too, the profile is created in a single operation, i. H. one pass through the forming roller system, but subjected to the deformation at several spatially consecutive points.

   The forming roller system can have a preforming group downstream of the feed rollers, the direction of action of which again runs approximately parallel to that of the feed rollers and which is followed by a finishing group which has forming rollers with directions of action running at an angle to one another.



   Due to the universal adjustability of the feed and discharge rollers. the rollers of the forming roller system and the total adjustability of these parts by means of the pivotable plate 1 ensures a completely straight and strictly aligned passage of the material and uniform contact of the same to the rollers performing the forming. As a result, even when using roller groups with effective directions running at an angle to one another, uniform contact of all rollers against the material and thus uniform processing of the same over all surfaces to be deformed is achieved and the risk of the pressure or pressure to be exerted on the material being eliminated.

   Counterpressure is absorbed by the supply or discharge rollers, so that the forming roller affected by this undesirable relief cannot work fully. By avoiding these deposits, very complicated profiles are also obtained with the greatest accuracy according to the invention.
