Description
Vorrichtung zum Richten von Rohren, Rundstangen o. dgl. Zum Richten von Walzstäben; Rohren u. dgl. werden Richtmaschinen verwendet, die meist mehrere Rollen aufweisen, zwischen denen das Walzgut hindurchgezogen wird.Device for straightening pipes, round bars or the like. For straightening of rolled bars; Pipes and the like. Straightening machines are used, usually several Have rollers between which the rolling stock is pulled through.
Bei den Rollenrichtmaschinen ist die Achse der Rallen senkrecht zur Bewegungsrichtung des Walzgutes angeordnet, während die Schrägwalzrichtmaschinen Rollen mit in der Fortbewegungsrichtung winklig angeordneter Achse aufweisen, Bei den Richtmaschinen beider Bauarten wird .das Walzgut geradlinig zur Einsteckrichtung fortbewegt.In roller straightening machines, the axis of the rails is perpendicular to the Direction of movement of the rolling stock arranged while the cross roll straightening machines Have rollers with an axis arranged at an angle in the direction of movement, at the straightening machines of both types. the rolling stock is straight to the insertion direction moved.
Alle bisher bekannten Bauarten haben den Nachteil, daß der Kopf des Werkstückes kaum gerichtet werden kann. Insbesondere bei den Rollenrichtmaschinen ergibt sich infolge der versetzten Anordnung der Rollen am.Vorderende des Werkstückes eine Abweichung, die mindestens so laug ,ist wie der Abstand der beiden letzten Rollen voneinander.All previously known types have the disadvantage that the head of the Workpiece can hardly be straightened. Especially with the roller straightening machines results from the staggered arrangement of the rollers at the front end of the workpiece a deviation that is at least as long as the distance between the last two Roles from each other.
Die Erfindung hat den Zweck, stabförmiges Walzgut, wie Rohre u. dgl., über seine ganze Länge gleichmäßig zu richten. Dies geschieht vermittels einer Vorrichtung, in der mehrere in einer Ebene mit schräg zur Einsteckrichtung des Richtgutes gelagerte Richtrollen vorgesehen sind, denen in einem Abstand entsprechend dem Durchmesser des Richtgutes eine Richtplatte gegenüberliegt.The invention has the purpose of rod-shaped rolling stock, such as pipes and the like., straighten evenly over its entire length. This is done by means of a device in which several stored in one plane at an angle to the direction of insertion of the object to be straightened Straightening rollers are provided, which at a distance corresponding to the diameter of the object to be straightened is opposite a straightening plate.
Die Erfindung ist in der folgenden Beschreibung an Hand der beigefügten Zeichnung beispielsweise erläutert. In der Zeichnung zeigt Fig. z eine schematische Seitenansicht auf die Vorrichtung gemäß der Erfindung und Fig. "z eine Draufsicht auf dieselbe.The invention is described in the following description with reference to the accompanying drawings Drawing explained for example. In the drawing, FIG. Z shows a schematic Side view of the device according to the invention and FIG. "Z a plan view on the same.
Die Vorrichtung besteht aus mehreren in einer Ebene angeordneten Rollen a. Die Achsen b dieser Rollen stehen, wie Fig: zeigt, winklig zur Förderrichtung des Richtgutes c. Unter diesen Rollen a ist eine Richtplatte d angeordnet, und zwar in einem Abstand von den Rollen an, der dein Durchmesser des Richtgutes entspricht. Wird das Richtgut c in die Vorrichtung eingesteckt und werden die Rollen cc im Sinne des Pfeiles e gedreht, dann dreht sich das Richtgut im Sinne des Pfeiles f und wandert gleichzeitig nach vorn und seitlich im Sinne des Pfeiles g. Infolge dieser Drehbewegung wird das Richtgut über seine ganze Länge gleichmäßig gerade gerichtet, und die Bildung des -sogenannten kurzen Kopfes-ist ausgeschlossen:The device consists of several rollers arranged in one plane a. The axes b of these rollers are, as Fig: shows, at an angle to the conveying direction of the target item c. A straightening plate d is arranged under these rollers a, namely at a distance from the rollers that corresponds to the diameter of the target material. If the object to be straightened c is inserted into the device and the rollers cc in the sense of arrow e rotated, then the target rotates in the direction of arrow f and wanders simultaneously forwards and sideways in the direction of arrow g. As a result of this turning movement the material to be straightened is evenly straightened over its entire length, and the formation the so-called short head is excluded:
