Abstract

A leveling machine for metal sheet or strip with upper and lower leveling rollers offset relative to one another and supported by back-up rollers, which are located between web plates lying on adjustment wedges supported on roller blocks and cross ties, includes discharge rods reciprocating in the metal plate traveling direction and disposed between the web plates.

Description

Die Erfindung betrifft eine Richtmaschine für Bleche und Bänder mit versetzt zueinander angeordneten oberen und unteren, von Stützrollen beaufschlagten Richtwalzen, wobei die Stützrollen zwischen Stegblechen angeordnet sind, die auf Anstellkeilen über die Walzenstühle und Quertraversen abgestützt sind, und mit unterhalb der unteren Stützrollen und oberhalb des unteren Walzenstuhls angeordneten Fördereinrichtungen zur Sinterabfuhr.The invention relates to a straightening machine for sheets and strips with staggered upper and lower straightening rollers acted upon by support rollers, the support rollers being arranged between web plates which are supported on adjusting wedges above the roller mills and crossbeams, and below the lower support rollers and above the Lower roller mill arranged conveyors for sinter removal.

Um den beim Richten von Blechen und Bändern unvermeidlich anfallenden Sinter oder sonstige Schmutzanteile aus dem Richtbereich abführen zu können, weisen bekannte Richtmaschinen im Walzenstuhl jeweils zwischen den Stegblechen und damit in großer Anzahl Schlitze auf, die sich bis durch die untere Quertraverse fortsetzen. Jedoch reichen selbst große bzw. breite Schlitze nicht aus, um zu verhindern, daß der Sinter, der meist mit z.B. Fett oder Öl vermischt ist, was ein Anbacken begünstigt, die Schlitze zusetzt. Abgesehen davon bedeuten die Schlitze eine unnötige Schwächung von Walzenstuhl und Quertraverse, und außerdem müssen zusätzliche Abschirmungen vorgesehen werden, da der Sinter die gesamten Bewegungsteile der Richtmaschine durchläuft.In order to be able to remove the sintering or other dirt that is unavoidable when straightening sheets and strips, known straightening machines in the roller mill each have between the web sheets and thus a large number of slots that continue through the lower crossbar. However, even large or wide slots are not sufficient to prevent the sinter, which is usually associated with e.g. Fat or oil is mixed, which promotes caking and clogs the slots. Apart from this, the slots mean an unnecessary weakening of the roller mill and cross-beam, and additional shields must also be provided, since the sinter passes through the entire moving parts of the straightening machine.

Bei einer durch die JP-A-63 104 724 bekannt gewordenen Richtmaschine der eingangs genannten Art sind zur Sinterabfuhr Förderbänder vorgesehen, von denen sich eins unterhalb der unteren Stützrollen und oberhalb des unteren Walzenstuhls befindet, das den während des Richtprozesses von dem Blechband herunterfallenden Sinter ausfördert und an ein zweites Förderband abgibt, das den Sinter in einen seitlich neben der Richtmaschine bereitstehenden Sammelwagen abwirft. Das in der Richtmaschine angeordnete Förderband vergrößert die Bauhöhe der Richtmaschine, und da der Sinter auch hier wiederum die gesamten Bewegungsteile der Richtmaschine durchläuft, sind Materialanhäufungen und damit das Herunterfallen des Sinters behindernde Anbackungen nicht auszuschließen.In a straightening machine of the type mentioned at the beginning of JP-A-63 104 724, conveyor belts are provided for sinter removal, one of which is located below the lower support rollers and above the lower roller mill, which conveys the sinter falling off the sheet metal belt during the straightening process and delivers it to a second conveyor belt, which throws the sinter into a collecting trolley that is on the side next to the straightening machine. The conveyor belt arranged in the straightening machine increases the overall height of the straightening machine, and since the sinter also passes through the entire moving parts of the straightening machine here, material accumulations and thus the sinters falling down can not be ruled out.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Richtmaschine so zu gestalten, daß die Sinterabfuhr ohne die genannten Nachteile sichergestellt ist.The invention has for its object to design a generic straightening machine so that the sinter removal is ensured without the disadvantages mentioned.

Diese Aufgabe wird erfindungsgemäß durch eine Richtmaschine mit den Merkmalen des Patentanspruchs 1 gelöst. Somit läßt sich der anfallende Sinter mittels der kontinuierlich, langsam hin- und herfahrenden Stangen austragen, von denen jeweils eine zwischen zwei benachbarten Stegblechen, die seitlich einen geschlossenen Raum bzw. Austragkanal begrenzen, angeordnet ist. Über die Breite der Richtmaschine sind insgesamt etwa 30 Austragstangen vorhanden. Der Sinter hat damit keine Gelegenheit, sich in den geschlossenen Austragkanälen im Blechbereich festzusetzen, und da Schlitze zur Sinter- bzw. Schmutzabfuhr entfallen können, werden weder der Walzenstuhl noch die untere Quertraverse geschwächt.This object is achieved according to the invention by a straightening machine with the features of patent claim 1. The resulting sinter can thus be discharged by means of the continuously, slowly moving rods, one of which is arranged between two adjacent web plates which laterally delimit a closed space or discharge channel. There are a total of about 30 discharge bars across the width of the straightening machine. Sintering therefore has no opportunity to get stuck in the closed discharge channels in the sheet metal area, and since slots for sintering and dirt removal can be omitted, neither the roller mill nor the lower cross-beam are weakened.

Es wird vorgeschlagen, daß ein Austragwagen die Austragstangen aufnimmt, der zu diesem Zweck vorteilhaft kopfseitig einen sich über die Breite der Richtmaschine erstreckenden Tragbalken für die Austragstangen aufweisen kann. Die Austragstangen lassen sich bspw. mit ihnen in dem Tragbalken zugeordneten Aufnahmen verschrauben oder durch Einrasten lösbar verbinden.It is proposed that a discharge carriage receive the discharge rods, which for this purpose can advantageously have a support beam for the discharge rods that extends across the width of the straightening machine. The discharge rods can, for example, be screwed to receptacles assigned to them in the support beam or releasably connected by latching.

Nach einem Vorschlag der Erfindung kann eine Austragstange aus zwei durch schräggestellte Bleche miteinander verbundenen Winkeleisen bestehen. Auf diese Weise ergibt sich eine einfache Herstellung der Austragstangen, und die schräggestellten Bleche erfüllen neben ihrer die Winkeleisen verbindenden Funktion außerdem noch eine den Schmutz bzw. Sinter lösende Kratzerfunktion.According to a proposal of the invention, a discharge rod can consist of two angle irons connected to one another by inclined sheets. In this way, the discharge rods are easy to manufacture, and the inclined sheets also perform a scratch function that removes the dirt or sinter in addition to their function connecting the angle iron.

Es empfiehlt sich, daß die Ausstragstangen an ihren Kopfenden mit einem Überstand ausgebildet sind. Die entsprechend dem Hub des Austragwagens somit über den eigentlichen Walzenstuhlbereich der Richtmaschine hinaus verlängerten Austragstangen lassen sich aufgrund ihres Überstandes abstützen, und zwar sowohl bei ein- als auch bei ausgebautem Walzenstuhl.It is recommended that the discharge rods are formed with a protrusion at their head ends. The discharge rods, which are thus extended beyond the actual roller mill area of the straightening machine in accordance with the stroke of the discharge carriage, can be supported on the basis of their protrusion, both when the roller mill is installed and when it is removed.

Weiterhin empfiehlt es sich, daß der Austragwagen lösbar an einen Schubstangen-Antrieb angeschlossen ist. Da zum schnellen Walzenstuhlwechsel die Austragstangen - wie zuvor gesagt - über eine weite Strecke aus der Richtmaschine herausgefahren werden müssen, läßt sich durch einfaches Umsetzen der an dem Wagen angelenkten Schubstange ein großer Ausfahrhub erreichen, bis der Wagen mit den Austragstangen in eine den Walzenstuhlwechsel nicht mehr störende Außerbetriebsposition gebracht ist.It is also recommended that the discharge trolley be detachably connected to a push rod drive. Since the discharge rods have to be moved out of the straightening machine over a long distance to quickly change the roll mill, a large extension stroke can be achieved simply by moving the push rod articulated on the carriage until the carriage with the discharge rods no longer changes the roll mill disturbing out of service position is brought.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel des Gegenstandes der Erfindung näher erläutert ist. Es zeigen:

Die Rollenrichtmaschine 1 weist einen aus zwei am Fundament verankerten Ständern 2, 3 bestehenden Maschinenrahmen auf. Die Ständer 2, 3 sind durch eine obere Rahmentraverse 4a sowie eine untere und eine obere Quertraverse 4, 5 starr miteinander verbunden. An der oberen Quertraverse 4 ist ein oberer Walzenstuhl 6 gehalten; ein unterer Walzenstuhl 7 ist verfahrbar auf der unteren Quertraverse 5 angeordnet. Die obere Quertraverse 4 ist über Anstellzylinder 10 gegen die untere Quertraverse 5 anstellbar; jeweils ein- und auslaufseitig an den Ecken angeordnete und somit insgesamt vier Anstellzylinder 10 greifen an die obere Quertraverse 4 an.The roller leveler 1 has a machine frame consisting of two stands 2, 3 anchored to the foundation. The stands 2, 3 are rigidly connected to one another by an upper frame cross member 4a and a lower and an upper cross member 4, 5. An upper roller mill 6 is held on the upper crossbar 4; a lower roller mill 7 is movably arranged on the lower crossbar 5. The upper crossmember 4 can be adjusted against the lower crossmember 5 by means of a setting cylinder 10; each on the inlet and outlet side Arranged at the corners and thus a total of four positioning cylinders 10 engage the upper crossbar 4.

Auf dem unteren Walzenstuhl 7 sind Rollenanstellkeile 8 gelagert, die durch je einen Druckmittelzylinder 9 verschiebbar sind. Jedem Anstellkeil 8 ist ein Lagerträgerkeil 11 für untere Richtrollen 12 und diese abstützenden Stützrollen 13 zugeordnet; zwischen den Stützrollen 13 sind die Lagerungen der Richtrollen 12 aufnehmende Stegbleche 14 angeordnet. Weiterhin sind mehrere obere Richtrollen 15 an ihren Ballen abgestützt, und zwar mittels Stützrollen 17, die sich zwischen Stegblechen 16 befinden. Die oberen Richt- und Stützrollen 15, 17 sind an einem Lagerträgerkeil 18 gelagert. Jeder der benachbarten Lagerträgerkeile 18 ist an einen Anstellkeil 21 abgestützt, dessen andere Seite am oberen Walzenstuhl 6 anliegt. Die Anstellkeile 21 sind durch je einen Druckmittelzylinder 22 verschiebbar. Die oberen und unteren Richtrollen 15, 12 sind einzeln angetrieben und über Gelenkwellen mit einem nicht dargestellten Antrieb verbunden.Roller positioning wedges 8 are mounted on the lower roller mill 7 and can be displaced by one pressure medium cylinder 9 each. A bearing support wedge 11 for lower straightening rollers 12 and supporting rollers 13 supporting them is assigned to each wedge 8; between the support rollers 13 the bearings of the straightening rollers 12 receiving web plates 14 are arranged. Furthermore, several upper straightening rollers 15 are supported on their bales, namely by means of support rollers 17, which are located between web plates 16. The upper straightening and support rollers 15, 17 are mounted on a bearing carrier wedge 18. Each of the adjacent bearing carrier wedges 18 is supported on an adjusting wedge 21, the other side of which lies against the upper roller mill 6. The adjusting wedges 21 can be displaced by one pressure medium cylinder 22 each. The upper and lower straightening rollers 15, 12 are individually driven and connected to a drive (not shown) via cardan shafts.

Wie sich näher den Figuren 2a, 2b und 3a, 3b entnehmen läßt, ist der Rollenrichtmaschine 1 an ihrem einlaufseitigen Ende ein in einer Führung 24 in Blechlaufrichtung 25 kontinuierlich langsam hin- und herbeweglicher, unterhalb des Rollgangs 26 für die in die Richtmaschine 1 einlaufenden Bleche angeordneter Austragwagen 27 - nachfolgend lediglich Wagen genannt - zugeordnet (vgl. Figur 2b). Zum Hin- und Herverfahren ist der Wagen 27 an einen Schubstangen-Antrieb 28 angeschlossen. An seinem der Richtmaschine 1 zugewandten Ende weist der Wagen 27 einen sich über die gesamte Breite der Richtmaschine erstreckenden Tragbalken 29 (vgl. Figur 3b) auf. Der Tragbalken 29 ist mit zahlreichen, parallel nebeneinanderliegenden Austragstangen 31 versehen, die mit ihren dem Wagen 27 zugewandten Enden mit dem Tragbalken 29 verbunden sind. Jede Austragstange 31 besteht gemäß Figur 3a aus zwei Winkeleisen 32, die über schräggestellte Bleche 33 zu einer festen Einheit miteinander verbunden sind.As can be seen in more detail in FIGS. 2a, 2b and 3a, 3b, the roller straightening machine 1 at its inlet end is continuously and slowly movable back and forth in a guide 24 in the sheet metal running direction 25, below the roller table 26 for the sheets entering the straightening machine 1 arranged discharge carriage 27 - hereinafter referred to simply as carriage - assigned (see FIG. 2b). The carriage 27 is connected to a push rod drive 28 for the back and forth process. At its end facing the straightening machine 1, the carriage 27 has a support beam 29 which extends over the entire width of the straightening machine (cf. FIG. 3b). The support beam 29 is provided with numerous parallel discharge rods 31 which are connected to the support beam 29 by their ends facing the carriage 27. According to FIG. 3a, each discharge rod 31 consists of two angle irons 32, which are connected to one another via inclined plates 33 to form a fixed unit.

Jeweils eine Austragstange 31 ist in einem nach unten hin geschlossenen Raum zwischen zwei benachbarten Stegblechen 14 angeordnet und von einer solchen Länge, daß sie durch die Richtmaschine 1 hindurch bis in den Auslaufbereich 34 (vgl. Figur 2a) reicht. Dort, d.h. an ihren Kopfenden sind die Austragstangen 31 mit einem Überstand 35 ausgebildet, der dem Hub des Wagens 27 entspricht und eine ausreichende Abstützung der Austragstangen 31 gewährleistet. Bei eingebautem Walzenstuhl 7 stützen sich die Austragstangen 31 mit ihren Überständen 35 auf einer im Auslaufbereich 34 angeordneten Rolle 36 ab; ist der Walzenstuhl 7 ausgebaut, wie zum Walzenwechsel, müssen die Austragstangen 31 aus dem gesamten Walzenstuhlbereich herausgefahren werden. In diesem Fall stützen sie sich auf einem Stützträger 39 ab.One discharge rod 31 is arranged in a downwardly closed space between two adjacent web plates 14 and is of such a length that it extends through the straightening machine 1 into the outlet area 34 (see FIG. 2a). There, i.e. at their head ends the discharge rods 31 are formed with a projection 35 which corresponds to the stroke of the carriage 27 and ensures adequate support of the discharge rods 31. When the roller mill 7 is installed, the discharge rods 31 are supported with their projections 35 on a roller 36 arranged in the outlet region 34; if the roller mill 7 is removed, as for changing the roller, the discharge rods 31 must be moved out of the entire roller mill area. In this case, they are supported on a support bracket 39.

Während des Richtbetriebes wird dem Wagen 27 von dem Schubstangen-Antrieb 28 eine langsame, kontinuierliche hin- und hergehende Bewegung auferlegt, so daß die Austragstangen 31 aus ihrer in den Figuren 2a und 3a dargestellten hinteren Endposition stetig in entgegengerichteter Richtung in ihre dortige Endposition bewegt werden, und umgekehrt. Während dieser Hubbewegungen fördern die Austragstangen 31 von den zu richtenden Blechen bzw. Bändern herabfallenden, sich in den geschlossenen Räumen zwischen den Stegblechen ansammelnden Schmutz bzw. Sinter aus der Richtmaschine heraus, wo er ohne in Kontakt mit den Bewegungsteilen der Richtmaschine 1 zu kommen, gesammelt und temporär oder kontinuierlich abgefördert werden kann.During the straightening operation, a slow, continuous reciprocating movement is imposed on the carriage 27 by the push rod drive 28, so that the discharge rods 31 are moved continuously from their rear end position shown in FIGS. 2a and 3a in the opposite direction to their end position there , and vice versa. During these lifting movements, the discharge rods 31 convey from the straightening machine from the sheets or strips to be straightened, dirt or sinter accumulating in the closed spaces between the web plates, where they collect without coming into contact with the moving parts of the straightening machine 1 and can be removed temporarily or continuously.

Zum Wechseln des unteren Walzenstuhles 7 werden die Austragstangen 31 mittels des Wagens 27 aus der Richtmaschine 1 vollständig herausgezogen, wozu die an den Wagen 27 angelenkte Schubstange 37 des kurbelartigen Schubstangen-Antriebes 28 lediglich umgesetzt zu werden braucht. Eine zunächst ziehende Bewegung - wie in Figur 2b dargestellt - wird nach dem Umsetzen der Schubstange 37 durch eine schiebende und nach dem abermaligen Umsetzen wieder eine ziehende Bewegung abgelöst. Das Einfahren der Austragstangen 31 in die zwischen den Stegblechen 14, die sich oberhalb einer Abschlußplatte 40 und die Keilpaare 11, 8 von oben einschließenden U-Blechen 38 befinden, gebildeten Kanäle geschieht in umgekehrter Reihenfolge. Die Austragstangen 31 sorgen somit für eine kontinuierliche Sinter- bzw. Schmutzabfuhr, wozu es keiner den Walzenstuhl 7 und die untere Quertraverse 5 schwächenden, unvermeidlich zu Verstopfungen führenden Schlitze mehr bedarf.To change the lower roller mill 7, the discharge rods 31 are completely pulled out of the straightening machine 1 by means of the carriage 27, for which purpose the push rod 37 articulated on the carriage 27 of the crank-like push rod drive 28 need only be implemented. An initially pulling movement - as shown in FIG. 2b - is carried out by a pushing and after the repositioning again a pulling movement. The insertion of the discharge rods 31 into the channels formed between the web plates 14, which are located above an end plate 40 and the wedge pairs 11, 8 from above, enclosing U-plates 38, takes place in reverse order. The discharge rods 31 thus ensure continuous sintering or dirt removal, for which it is no longer necessary for slots which weaken the roller mill 7 and the lower cross-member 5 and inevitably lead to blockages.
