Description
Die Erfindung betrifft eine Verbesserung der durch Patent 503092 geschützten Richtmaschine. Die Erfindung besteht darin, daß statt der in Patent 503 092 angeordneten nicht angetriebenen mittleren Arbeitsringe an sich bekannte nicht angetriebene hyperbolische Walzen angeordnet werden, deren Welle parallel zur Drehebene der angetriebenen Arbeitsringe liegt.The invention relates to an improvement of the straightening machine protected by patent 503092. The invention consists in that instead of that arranged in patent 503 092 non-driven middle working rings known per se non-driven hyperbolic rollers are arranged, the shaft parallel to the The plane of rotation of the driven working rings lies.
In den Zeichnungen zeigt
Fig. ι einen waagerechten Schnitt.In the drawings shows
Fig. Ι a horizontal section.
Fig. 2 ist ein senkrechter Schnitt durch die angetriebenen Arbeitsringe.Figure 2 is a vertical section through the driven working rings.
Fig. 3 ist ein Schnitt durch den Lagerkasten der Hyperbelwalze.Fig. 3 is a section through the storage box of the hyperbolic roller.
Wird, wie in Fig. 2 durch den eingezeichneten Pfeil angedeutet, der angetriebene Arbeitsring im Uhrzeigersinne gedreht, so erhält das durchgehende Richtgut 14 den gleichen Drehsinn und wird wie eine Schraube fortschreitend durch die Maschine weiterbewegt. Der im Patent 503 092 vorgesehene nicht angetriebene mittlere Arbeitsring müßte nun, wenn er zur Anlage an das im Uhrzeigersinne sich drehende fortschreitende Richtgut gebracht wird, ebenfalls im Uhrzeigersinne umlaufen sollen. Der mittlere Arbeitsring wird aber infolge seiner Lagerreibung an der Drehung im Sinne des Richtgutvorschubs gehindert. Er sucht sich entgegen der Richtgutbewegung in seinem Gehäuse zu drehen, so daß er den Richtgutvorschub hemmt.If, as indicated in Fig. 2 by the arrow drawn, the driven working ring rotated clockwise, the continuous material to be straightened 14 receives the same Direction of rotation and is progressively moved through the machine like a screw. The non-driven middle working ring provided in patent 503 092 would now have to when it is brought to bear on the advancing material to be straightened, rotating in a clockwise direction will also circulate clockwise. The middle working ring will, however prevented from rotating in the sense of the target feed due to its bearing friction. He tries to turn against the movement of the material to be straightened in his housing, so that he can Target feed inhibits.
Die gemäß der Erfindung angeordnete von oben angreifende Hyperbelwalze aber erhält eine mit der Richtgutbewegung übereinstimmende Drehbewegung.The hyperbolic roller which is arranged according to the invention and which acts from above is retained a rotary movement that corresponds to the movement of the material to be straightened.
