Description

Die Erfindung betrifft eine Schmiervorrichtung für einen spreizbaren Haspeldorn zum Aufwickeln bandförmigen Walzgutes gemäß dem Oberbegriff des Patentanspruchs 1. Ein derartiger Haspeldorn mit einer Schmiervorrichtung ist aus der DE 2032542 A1 bekannt.
Weitere Haspeldorne der gattungsgemäßen Art sind beschrieben, in der europäischen Patentanmeldung 00 02 652. Sie sind als Spreizdorne ausgebildet, um das aufgewickelte Blechbund von der Haspelwelle abziehen zu können oder das Aufstecken eines zum Abwickeln bereitzustellenden Bundes auf die Haspelwelle in einfacher Weise zu ermöglichen. Zum Spreizen werden die an der Domwelle vorgesehenen Keilflächen relativ zu den Spreizsegmenten verschoben, so daß sich letztere radial nach innen oder außen bewegen. Zur Einleitung der Spreizbewegung sind verschiedene mechanische Antriebssysteme bekannt, denen allen ein Problem gemeinsam ist, nämlich das der ausreichenden Schmierung der unter Last gegeneinander geführten Gleitflächen.The invention relates to a lubricating device for an expandable coiler mandrel for winding strip-shaped rolling stock according to the preamble of patent claim 1. Such a coiler mandrel with a lubricating device is known from DE 2032542 A1.
Further reel mandrels of the generic type are described in European patent application 00 02 652. They are designed as expanding mandrels in order to be able to pull the coiled sheet metal bundle off the reel shaft or to allow a coil to be made available for unwinding to be attached to the reel shaft in a simple manner. For spreading, the wedge surfaces provided on the dome shaft are displaced relative to the spreading segments, so that the latter move radially inwards or outwards. Various mechanical drive systems are known for initiating the spreading movement, all of which have one problem in common, namely that of sufficient lubrication of the sliding surfaces which are guided against one another under load.

Je nach der Anzahl der vorhandenen Keilflächen ergibt sich eine Vielzahl von mit Schmiermittel zu versorgenden Schmierstellen, die üblicherweise mit Handschmiernippeln ausgerüstet sind und regelmäßig geschmiert werden müssen. Depending on the number of wedge surfaces available, there is a multitude of with Lubricants to be supplied to lubrication points, usually with Hand lubrication nipples are equipped and must be lubricated regularly.

Bei ca. 50 Schmierstellen bedeutet das Abschmieren der Haspeldorne nicht nur einen großen Aufwand; das Abschmieren von Hand erfordert gleichzeitig einen längeren Stillstand der Anlage und damit Produktionsausfall. Zusätzlich beinhaltet die schlechte Zugänglichkeit der Schmierstellen am Haspeldorn eine erhebliche Unfallgefahr. Auch können einzelne Schmierstellen übersehen oder vergessen werden, was zur Beschädigung der Gleitflächen und schlimmstenfalls zum Ausfall des Haspels führen kann.With around 50 lubrication points, greasing the reel mandrels does not mean just one great effort; hand lubrication requires a longer time Plant downtime and thus loss of production. In addition, the bad includes Access to the lubrication points on the coiler mandrel poses a significant risk of accidents. Also individual lubrication points can be overlooked or forgotten, what for Damage to the sliding surfaces and, in the worst case, lead to the reel failing can.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine sichere Schmierstoffversorgung aller Einzelschmierstellen eines spreizbaren Haspeldornes sicherzustellen und die Stillstandszeiten durch Verkürzung der Instandhaltungszeiten zu verringern. Zusätzlich soll die Unfallgefahr vermieden werden.Proceeding from this, the object of the present invention is a safe one Lubricant supply to all individual lubrication points of an expandable coiler mandrel ensure and downtimes by reducing maintenance times to reduce. In addition, the risk of accidents should be avoided.

Gelöst wird diese Aufgabe erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1.This object is achieved according to the invention with the characteristic Features of claim 1.

Durch den Vorschlag der Erfindung lassen sich die Schmierzeiten des Haspeldorns und damit die Stillstandszeiten der Anlage erheblich verkürzen. Durch Vereinfachung des Schmiervorganges läßt sich die Unfallgefahr ausschalten; die Domstandzeit wird durch die gleichmäßige und vollständige Schmiermittelversorgung erhöht, so daß durch die längere Verfügbarkeit der Anlage die Produktionsmenge gesteigert werden kann.The proposal of the invention makes it possible to lubricate the reel mandrel and thus significantly reduce the downtimes of the system. By simplification the lubrication process can eliminate the risk of accidents; the cathedral life will increased by the even and complete supply of lubricant, so that the production volume can be increased due to the longer availability of the system can.

Dadurch, daß alle Schmierstellen der Domwelle zentral von einem Punkt ausgehend abgeschmiert werden, wird die Schmiermittelversorgung vereinfacht. Durch Verbindung jeder Schmierstelle über eine separate Längsbohrung mit der Fettverteilung ist sichergestellt, daß keine Schmierstelle ausgelassen wird.Because all lubrication points of the dome shaft start centrally from one point are lubricated, the lubricant supply is simplified. By Connection of each lubrication point with a separate longitudinal bore Grease distribution ensures that no lubrication point is left out.

Dadurch, daß die ringförmigen Quernuten gegenüber der zentralen Bohrung in der Dornwelle abgedichtet sind, wird ein gezieltes Leiten des Schmiermittels zu den einzelnen Bohrungen möglich, wobei nach einem anderen Merkmal der Erfindung die jeder Schmierstelle zugeführte Fettmenge einstellbar ist.The fact that the annular transverse grooves opposite the central bore in the Mandrel shaft are sealed, the lubricant is directed to the individual holes possible, the according to another feature of the invention the amount of grease supplied to each lubrication point is adjustable.

Ein besonderer Vorteil der vorliegenden Erfindung besteht darin, daß die zentrale Fettverteilung automatisch mit einer Fettzuführleitung koppelbar ist. Auf diese Weise wird es möglich, den gesamten Schmiervorgang des Haspeldornes zu automatisieren und damit sowohl die Unfallgefahr, wie auch Fehler des Bedienungspersonals auszuschalten.A particular advantage of the present invention is that the central Fat distribution can be automatically coupled to a fat supply line. In this way it becomes possible to automate the entire lubrication process of the reel mandrel and thus both the risk of an accident and errors by the operating personnel turn off.

Auf den Keilflächen 3 und 4 sind (die nicht dargestellten) Spreizsegmente gleitend geführt und in der bei 4 angedeuteten Nut gegen Fliehkräfte gehalten. Alle Keilflächen 2 und 3 sind mit einem Netz von Schmiernuten versehen, die in der Zeichnung als Schmierstellen 5 bezeichnet sind. Die Schmierstellen 5 sind einzeln abzuschmieren, was erfindungsgemäß über die dreiteilige Patrone 6a, 6b, 6c erfolgt, die in eine zentrale Bohrung 7 der Domwelle einschiebbar ist. Die Patrone 6a, 6b, 6c ist, wie der Schnitt A-A zeigt, mit einer Vielzahl längsverlaufender Bohrungen 8 versehen, von denen jede Bohrung 8 mit einer von ebensovielen ringförmigen Quernuten 9 korrespondiert, die am Außenumfang der Patrone 6a, 6b, 6c vorgesehen sind. Jede ringförmige Quernut ist gegenüber der Bohrung 7 bei 10 abgedichtet, so daß bei entsprechender Verbindung der ringförmigen Quernut 9 mit einer zu den Keilflächen 2, 3 führenden Bohrung 11, über die Längsbohrung 8, die ringförmige Quernut 9 und die Zuführbohrung 11 eine Versorgung der Schmierstellen 5 gezielt und individuell ausführbar ist.In the schematic representation of the single drawing figure, that with 1 designated mandrel shaft of an expandable reel mandrel recognizable on its circumference in the longitudinal direction one behind the other four wedge surfaces 3 distributed over the circumference and 4 are arranged. On the wedge surfaces 3 and 4 are (not shown) Spreading segments slidably guided and in the groove indicated at 4 against centrifugal forces held. All wedge surfaces 2 and 3 are provided with a network of lubrication grooves that are designated as lubrication points 5 in the drawing.
