Description

Die Erfindung betrifft eine Richtmaschine für Bleche und Bänder mit einer oberen und einer unteren Richtwalzenreihe und mit mehreren über die Länge der Richtwalzen nebeneinander angeordneten Stützrollen, wobei jeweils in Durchlaufrichtung der Bleche aufeinanderfolgende Stützrollen mehrerer Richtwalzen an Lagerträgern gelagert sind, die senkrecht-zur Blechebene geführt und durch verschiebbare Keile abgestützt sind.The invention relates to a straightening machine for sheets and strips with an upper and a lower row of straightening rollers and with a plurality of support rollers arranged alongside one another over the length of the straightening rollers, successive support rollers of a plurality of straightening rollers being mounted in the direction of travel of the sheets on bearing supports which are guided perpendicularly to the sheet plane and are supported by sliding wedges.

Bei einer bekannten Richtmaschine sind die oberen Richtwalzen an einem Oberrahmen gelagert, der durch angetriebene Spindeln mit senkrechten Holmen des Maschinengestells höhenverstellbar verbunden ist. Die unteren Richtwalzen sind an einem Unterrahmen gelagert, der auf beiden Seiten mit bogenförmigen Flächen auf zwischen den vertikalen Holmen geführten Sätteln schwenkbar gelagert ist. Die Sättel sind mit geneigten Flächen auf horizontal verschiebbaren Keilen höhenverstellbar im Gestell abgestützt. Jede der oberen und unteren Richtwalzen ist durch mehrere Stützrollen an ihren Ballen abgestützt. Die in Durchlaufrichtung aufeinanderfolgend angeordneten Stützrollen mehrerer Richtwalzen sind jeweils als Satz an Lagerträgern gelagert. Die Lagerträger sind einzeln über verstellbare Keile am Oberrahmen bzw. am Unterrahmen abgestützt. Durch gesonderte Höhenverstellung jedes Stützrollensatzes kann die Biegung der Richtwalzen gemeinsam eingestellt werden. Durch geradliniges Heben und Senken bzw. durch Schwenken des Unterrahmens können die unteren Richtwalzen gemeinsam in die dem erforderlichen Richtspalt entsprechende Position gebracht werden.In a known straightening machine, the upper straightening rollers are mounted on an upper frame, which is connected in a height-adjustable manner by means of driven spindles to vertical bars of the machine frame. The lower straightening rollers are mounted on a subframe which is pivotally mounted on both sides with curved surfaces on saddles guided between the vertical bars. The saddles are supported in the frame with inclined surfaces on horizontally displaceable wedges. Each of the upper and lower straightening rollers is supported on their bales by several support rollers. The support rollers of several straightening rollers, which are arranged successively in the direction of flow, are each mounted as a set on bearing supports. The bearing brackets are individually supported by adjustable wedges on the upper frame or on the lower frame. The bending of the straightening rollers can be adjusted jointly by separately adjusting the height of each support roller set. By lifting and lowering in a straight line or by swiveling the lower frame, the lower straightening rollers can be brought together into the position corresponding to the required straightening gap.

Die Konstruktion dieser Richtmaschine mit höhenverstellbaren oberen und unteren Rahmen bedingt eine aufwendige Bauart mit langen Holmen. Dabei ist die Maschinensteifigkeit wegen der Länge der Holme und ihrer Verbindung über Spindeln mit dem Oberrahmen sehr gering. Ein weiterer Nachteil ist, daß trotz aufwendiger Verstelleinrichtungen eine gesonderte Einstellung des Richtspaltes zwischen jeweils zwei Richtwalzen nicht möglich ist und daher der Richtspalt nicht beliebig variiert werden kann.The construction of this leveler with height-adjustable upper and lower frames requires an elaborate design with long bars. The machine rigidity is very low due to the length of the bars and their connection to the upper frame via spindles. Another disadvantage is that, despite complex adjustment devices, a separate adjustment of the straightening gap between two straightening rollers is not possible and therefore the straightening gap cannot be varied as desired.

Aufgabe der Erfindung ist die Schaffung einer konstruktiv einfacheren Richtmaschine in kompakterer und damit steiferer Bauweise, bei der die Richtwalzen unter Last sowohl gebogen als auch gegeneinander angestellt werden können. Zusätzlich soll eine gesonderte Einstellung des Richtspaltes zwischen einzelnen gegenüberliegenden Richtwalzen möglich sein.The object of the invention is to provide a structurally simpler straightening machine in a more compact and therefore more rigid construction, in which the straightening rollers can be bent as well as set against one another under load. In addition, a separate adjustment of the straightening gap between individual opposing straightening rollers should be possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die oberen und unteren Richtwalzen an einem mit einer Ständertraverse verbundenen oberen bzw. unteren Walzenstuhl beweglich gelagert und gegen die Kraft von Federelementen gegeneinander anstellbar sind, an dem auch die Lagerträger senkrecht zur Blechebene geführt sind, und daß bei einer Richtwalzenreihe jeweils einzelnen Richtwalzen zugeordnete Stützrollen an je einem sich parallel zu den Richtwalzen erstreckenden vertikal geführten Lagerkamm gelagert sind, die mit geneigter Unterseite auf je einem parallel zu den Richtwalzen längsverschiebbaren Keil verstellbar abgestützt sind.This object is achieved in that the upper and lower straightening rollers are movably mounted on an upper or lower roller mill connected to a stand cross member and can be adjusted against the force of spring elements, on which the bearing supports are also guided perpendicular to the sheet plane, and in that support rollers assigned to each straightening roller row are each supported on a vertically guided bearing comb which extends parallel to the straightening rollers and which are adjustably supported with an inclined underside on a wedge which is longitudinally displaceable parallel to the straightening rollers.

Auf diese Weise wird mit einfachen betriebssicheren Verstelleinrichtungen eine vielfältige Möglichkeit zur Verstellung gegen den Richtdruck und zur Biegung der Richtwalzen geschaffen.In this way, simple, reliable adjustment devices create a diverse possibility for adjustment against the straightening pressure and for bending the straightening rollers.

Darüber hinaus wird bei einer Richtwalzenreihe die Einstellung des Richtspaltes zwischen einzelnen gegenüberliegenden Richtwalzen ermöglicht. Aufwendige Verstelleinrichtungen wie Spindeln und Schwenksättel werden eingespart. Dadurch wird die Bauhöhe der Richtmaschine verringert und die Maschinensteifigkeit wesentlich verbessert.In addition, it is possible for a series of straightening rolls, the adjustment of the gap between individual SE opposite straightening rolls. Elaborate adjustment devices such as spindles and swivel saddles are saved. This reduces the height of the straightening machine and significantly improves machine rigidity.

Gemäß einem weiteren Merkmal der Erfindung sind die Lager der Richtwalzen durch am Walzenstuhl angebrachte Federpuffer im Sinne einer öffnung des Richtwalzensatzes gehalten. Dadurch sind die Richtwalzen in ständiger Anlage an den Stützrollen, wobei ihre Position und Biegekontur durch die Position der Stützrollen bestimmt ist.According to a further feature of the invention, the bearings of the straightening rolls are held by spring buffers attached to the roll mill in the sense of an opening of the straightening roll set. As a result, the straightening rollers are in constant contact with the support rollers, their position and bending contour being determined by the position of the support rollers.

Die Lager der Richtwalzen können weiterhin in einer Führung am Walzenstuhl nebeneinanderliegend aufgenommen sein.The bearings of the straightening rollers can also be accommodated in a guide on the roller mill lying side by side.

Sowohl die quer zu den Richtwalzen angeordneten als auch die parallel zu den Richtwalzen angeordneten Verstellkeile können durch Hydraulikzylinder verschiebbar sein, deren Beaufschlagung einzeln oder gemeinsam regelbar ist.Both the adjusting wedges arranged transversely to the straightening rollers and the adjusting wedges arranged parallel to the straightening rollers can be displaceable by hydraulic cylinders, the action of which can be regulated individually or together.

Ein weiterer Vorteil wird nach der Erfindung darin gesehen, daß die den einzelnen Richtwalzen zugeordneten Stützrollen derart an den Lagerstützen bzw. den Lagerkämmen gelagert sind, daß ihre Achsen abwechselnd in und entgegengesetzt zur Durchlaufrichtung des Bleches aus der vertikalen Achsebene der Richtwalzen verlagert sind. Dadurch werden die Richtwalzen in horizontaler Richtung definiert geführt.Another advantage is seen according to the invention in that the support rollers assigned to the individual straightening rollers are mounted on the bearing supports or the bearing combs in such a way that their axes are shifted alternately in and opposite to the direction of travel of the sheet from the vertical axis plane of the straightening rollers. As a result, the straightening rollers are guided in a defined manner in the horizontal direction.

In the drawing, an embodiment of the invention is shown. Show it:
  • F ig. 1 shows the cross section of a roll straightening machine and
  • 2 shows a longitudinal section along the line II-II in FIG. 1st

Das Gestell der dargestellten Richtmaschine besteht aus zwei am Fundament verankerten Ständern 1, die durch eine obere Traverse 2 und eine untere Traverse 3 starr verbunden sind. Ein oberer Walzenstuhl 4 ist an der oberen Traverse 2 befestigt und erstreckt sich bis in die Fensteröffnungen der Ständer 1. Drei obere Richtwalzen 5 sind mit ihren Lagern 6 aneinanderliegend zwischen im Bereich der Ständerfester befindlichen Führungen 7, 8 am oberen Walzenstuhl 4 vertikal beweglich gelagert. Die Lager 6 der oberen Richtwalzen 5 sind mit Kolbenstangen von am Walzenstuhl 4 befestigten Federpuffern 9 verbunden. Jede obere Richtwalze 5 ist durch mehrere nebeneinander angeordnete Stützrollen 10 an ihrem Ballen abgestütz.The frame of the straightening machine shown consists of two stands 1 anchored to the foundation, which are rigidly connected by an upper cross member 2 and a lower cross member 3. An upper roller mill 4 is fastened to the upper crossmember 2 and extends into the window openings of the stand 1. Three upper straightening rolls 5 are mounted with their bearings 6 adjacent to one another between guides 7, 8 located in the area of the stand fixed on the upper roll mill 4. The bearings 6 of the upper straightening rollers 5 are connected to piston rods of spring buffers 9 attached to the roller frame 4. Each upper straightening roller 5 is supported on its bale by a plurality of support rollers 10 arranged side by side.

Der obere Walzenstuhl 4 weist sich quer zu den Richtwalzen 5 erstreckende Führungen 11 auf, in denen Querkeile 12 aufgenommen sind. Jeder Querkeil 12 ist über eine Kupplung 13 mit der Kolbenstange eines Hydraulikzylinders 14 verbunden, der an einer Stützbrücke 15 befestigt ist. In den Führungsöffnungen 11 sind weiter Lagerträger 16 vertikal beweglich geführt, die mit geneigten Oberflächen an den Querkeilen 12 anliegen. Die Lagerträger 16 sind mit Stirnplatten 17 versehen, die an den Außenflächen des oberen Walzenstuhles 4 geführt sind. Jeweils drei in Durchlaufrichtung des Richtgutes aufeinanderfolgende Stützrollen 10 der Richtwalzen 5 sind an einem Lagerträger 16 gelagert.The upper roller mill 4 has guides 11 which extend transversely to the straightening rollers 5 and in which transverse wedges 12 are received. Each cross wedge 12 is connected via a coupling 13 to the piston rod of a hydraulic cylinder 14 which is fastened to a support bridge 15. In the guide openings 11, bearing supports 16 are further guided such that they can move vertically and bear against the transverse wedges 12 with inclined surfaces. The bearing supports 16 are provided with end plates 17 which are guided on the outer surfaces of the upper roller mill 4. In each case three support rollers 10 of the straightening rollers 5, which follow one another in the direction of flow of the straightening material, are mounted on a bearing bracket 16.

Die Federpuffer 9 bewirken über die Richtwalzen 5 und die Stützrollen 10 eine ständige Anlage der Lagerträger 16 an den Querkeilen 12. Hierfür können aber auch besondere Haltemittel am oberen Walzenstuhl 4 angeordnet sein.The spring buffers 9 bring about a constant contact of the bearing supports 16 with the straightening rollers 5 and the support rollers 10 Cross wedges 12. However, special holding means can also be arranged on the upper roller mill 4 for this purpose.

Die gesamte obere Richtwalzenreihe 5 kann durch gemeinsame Verschiebung aller Querkeile 12 vertikal verstellt werden. Zur Erzielung einer Biegung der oberen Richtwalzen 5 können die Querkeile 12 durch separate Beaufschlagung einzelner Hydraulikzylinder 14 in unterschiedliche Positionen gefahren werden, so daß die oberen Stützrollen 10 eine bogenförmig verlaufende Anlage für die oberen Richtwalzen 5 bilden.The entire upper straightening roller row 5 can be adjusted vertically by moving all cross wedges 12 together. To achieve a bend in the upper straightening rollers 5, the transverse wedges 12 can be moved into different positions by acting separately on individual hydraulic cylinders 14, so that the upper support rollers 10 form an arcuate system for the upper straightening rollers 5.

Ein unterer Walzenstuhl 18 ist auf der unteren Traverse 3 gelagert und weist im Bereich der Ständeröffnungen seitliche Führungen 19, 20 für jeweils 4 Lager 21 von unteren Richtwalzen 22 auf. Jedes der Lager 21 ist mit einem am unteren Walzenstuhl 18 befestigten Federpuffer 23 verbunden und kraftschlüssig am Walzenstuhl 18 gehalten. Der untere Walzenstuhl 18 ist mit parallel zu den Walzenachsen verlaufenden Führungen 24 für Längskeile 25 versehen. Auf einer Konsole 26 sind mehrere Hydraulikzylinder 27 gelagert, deren Kolbenstangen über Gelenkstücke 28 stirnseitig an den Längskeilen 25 zu deren Einzelverstellung befestigt sind. Auf den geneigten Flächen der Längskeile 25 liegen Lagerkämme 29 mit geneigter Unterseite auf, an denen untere Stützrollen 30 für je eine untere Richtwalze 22 gelagert sind.A lower roller mill 18 is mounted on the lower cross member 3 and has lateral guides 19, 20 in the area of the stator openings for 4 bearings 21 each of lower straightening rollers 22. Each of the bearings 21 is connected to a spring buffer 23 fastened to the lower roller mill 18 and held non-positively on the roller mill 18. The lower roller mill 18 is provided with guides 24 for longitudinal wedges 25 running parallel to the roller axes. A plurality of hydraulic cylinders 27 are mounted on a bracket 26, the piston rods of which are fastened on the end face to the longitudinal wedges 25 by individual pieces 28 for their individual adjustment. On the inclined surfaces of the longitudinal wedges 25 there are bearing combs 29 with an inclined underside, on which lower support rollers 30 for a lower straightening roller 22 are each mounted.

Durch Einschieben der Längskeile 25 werden die unteren Stützrollen 30 gegen die unteren Richtwalzen 22 gepreßt, wodurch jede einzelne Richtwalze 22 gegen die Haltekraft der Federpuffer 23 in Richtung auf die oberen Richtwalzen 5 angestellt werden kann. Beim Herausziehen der Längskeile 25 durch die Hydraulikzylinder 27 bewirken die Federpuffer 23 und die Schwerkraft das Absenken der unteren Richtwalzen 22 und Stützrollen 30. Bei separater Beaufschlagung der Hydraulikzylinder 27 kann der Richtspalt zwischen jeweils zwei Richtwalzen 5 und 22 unabhängig vom Richtspalt zwischen den übrigen Richtwalzen eingestellt werden. Durch gemeinsame Beaufschlagung der Hydraulikzylinder 27 können alle unteren Richtwalzen 22 zur öffnung des Richtspaltes gemeinsam verstellt werden.By pushing in the longitudinal wedges 25, the lower support rollers 30 are pressed against the lower straightening rollers 22, whereby each individual straightening roller 22 can be set against the holding force of the spring buffer 23 in the direction of the upper straightening rollers 5. When pulling the longitudinal wedges 25 through the hydraulic cylinders 27, the spring buffers 23 and Lowering the lower straightening rollers 22 and support rollers 30 by gravity. When the hydraulic cylinders 27 are acted upon separately, the straightening gap between two straightening rollers 5 and 22 can be set independently of the straightening gap between the other straightening rollers. By acting on the hydraulic cylinders 27 together, all of the lower straightening rollers 22 can be adjusted jointly to open the straightening gap.
