Abstract
Richtmaschine für Rohre und Stangen, insbesondere Schrägwalzen-Richtmaschine, mit zumindest einer Oberwalze und zumindest einer Unterwalze (1) mit Pinolen (4, 11), auf welchen die Ober- und die Unterwalze (1) drehbar gelagert sind, wobei die Pinolen (4, 11) entlang ihrer Längsachse (9) verschiebbar und um ihre Längsachse (9) drehbar gelagert sind, und mit Feststellmitteln, mit welchen die Pinolen (4, 11) in verschiedenen Positionen feststellbar sind, wobei die Pinole (4, 11) einen Hohlraum (5) aufweist, welcher ein Druckmittel enthält, dass der Hohlraum (5) Wandungen hat, welche bei Beaufschlagung des Druckmittels mit Druck nach außen gedrückt werden und so die Pinole (4, 11) in ihrer Position feststellen.Straightening machine for pipes and rods, in particular cross roll straightening machine, with at least one top roller and at least one bottom roller (1) with quills (4, 11), on which the top and bottom rollers (1) are rotatably mounted, the quills (4 , 11) are displaceable along their longitudinal axis (9) and are rotatable about their longitudinal axis (9), and with locking means with which the sleeves (4, 11) can be locked in different positions, the sleeve (4, 11) having a cavity (5), which contains a pressure medium that the cavity (5) has walls which are pressed outwards when pressure is applied to the pressure medium and thus fix the sleeve (4, 11) in its position.
Description
Die vorliegende Erfindung betrifft eine Richtmaschine für Rohre und Stangen insbesondere eine Schrägwalzen-Richtmaschine, mit zumindest einer Oberwalze und zumindest einer Unterwalze mit Pinolen, auf welchen die Ober- und die Unterwalze gelagert sind, wobei die Pinolen verschiebbar und um ihre Längsachse drehbar gelagert sind, und mit Feststellmitteln, mit welchen die Pinolen in verschiedenen Positionen feststellbar sind.The present invention relates to a straightener for Pipes and rods, in particular an inclined roll straightening machine at least one top roller and at least one bottom roller with quills, on which the upper and lower rollers are mounted, the Quills are slidable and rotatable about their longitudinal axis, and with locking means with which the quills in different Positions can be determined.
Eine derartige Richtmaschine ist
aus der Druckschrift
Der Erfindung liegt daher die Aufgabe zugrunde, eine Richtmaschine vorzuschlagen, bei welcher das Feststellen der Pinole mit gegenüber dem Stand der Technik einfacher montierbaren Feststellmitteln möglich ist.The invention is therefore the object to propose a straightener in which the detection opposite the quill the prior art is easier to install locking means.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Pinole einen Hohlraum aufweist, welcher ein Druckmittel als Feststellmittel enthält, und dass der Hohlraum Seitenwandungen hat, welche bei Beaufschlagung des Druckmittels mit Druck nach außen gedrückt werden und so die Pinole in ihrer Position feststellen. Durch die Beaufschlagung des Druckmittels mit Druck wird der Außendurchmesser der Pinole vergrößert. Durch die Durchmesservergrößerung, wird die Pinole in der entsprechenden Pinolenführung festgeklemmt.This object is achieved according to the invention solved, that the quill has a cavity which is a pressure medium contains as a locking device, and that the cavity has side walls, which when loaded of the pressure medium are pressed outwards with pressure and so the quill in determine their position. By applying the pressure medium with pressure the outside diameter the quill enlarged. By the diameter increase, the sleeve is clamped in the appropriate sleeve guide.
Gemäß der Erfindung kann der Hohlraum eine im Querschnitt beliebige insbesondere aber eine kreisförmige oder ringförmige Form haben. Ferner kann gemäß der Erfindung das Druckmittel eine Flüssigkeit sein. Vorteilhaft ist die Flüssigkeit dann ein Hydrauliköl oder ein Silikonöl.According to the invention, the cavity can be a in cross-section any particular but a circular or annular To have shape. Furthermore, according to the invention the pressure medium is a liquid his. The liquid is advantageous then a hydraulic oil or a silicone oil.
Das Druckmittel kann in einer anderen Ausführungsform aber auch durch ein mechanisches Spreizmittel gebildet werden. Dabei kann es sich zum Beispiel um einen Kegel handeln, welcher in den Hohlraum der Pinole eingedrückt wird, wobei der Hohlraum der Pinole einen entsprechenden Innenkonus aufweist, so dass beim Eindrücken des Kegels der Durchmesser der Pinole größer wird.The pressure medium can be in another embodiment but can also be formed by a mechanical expansion means. there it can be, for example, a cone that goes into the cavity the quill pressed in is, the cavity of the quill a corresponding inner cone has so that when pressed of the cone the diameter of the quill increases.
Weitere Merkmale und Vorteile der vorliegenden Erfindung werden deutlich anhand der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels unter Bezugnahme auf die beiliegende Zeichnung.
