Description
Die Erfindung betrifft eine Einrichtung zum Blankschleifen von verzundertem Warmband oder dessen freien Enden in einer Bandanlage insbesondere in Vorbereitung einer Verbindung durch Schweißen.The invention relates to a device for bright grinding of scaled Hot strip or its free ends in a strip system, especially in preparation a connection by welding.
Beim Schweißen von verzundertem Warmband, insbesondere in einem Bereich geringer Banddicke, beispielsweise kleiner 1,2 mm, ist dieser Schweißprozeß mit einer Abbrenn-Stumpf-Schweißmaschine nicht mehr möglich. Hier kann nur mit einer Laserschweißmaschine gearbeitet werden.When welding scaled hot strip, especially in one area This welding process is also of small thickness, for example less than 1.2 mm a flash butt welding machine is no longer possible. Here can only with a laser welding machine.
Eine Alternative zum Schweißen von verzundertem Band besteht darin, daß das Band vor dem Schweißen metallisch blank gereinigt wird. Hierfür gibt es bereits die Möglichkeit, auf der Schweißmaschine eine Schleifeinrichtung zu installieren, die mit einem Schleifkopf, oder mit einem Fräser arbeitet. Falls eine solche Installation nicht möglich ist, muß eine separate Schleifeinrichtung in die Bandlinie integriert werden.An alternative to welding scaled tape is that Band is cleaned bright metallic before welding. For this there are already the possibility of installing a grinding device on the welding machine, that works with a grinding head, or with a milling cutter. If such an installation is not possible, a separate grinding device must be integrated in the belt line become.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Blankschleifen von verzundertem Warmband anzugeben, welche den Schleifprozeß des verzunderten Bandes in möglichst kurzer Zeit durchführt, um erforderliche Stillstandszeiten des Bandes im Einlaufteil einer kontinuierlich arbeitenden Bandanlage möglichst weitgehend zu kürzen. Je weniger Zeit benötigt wird, desto kleiner kann ein Zwischenspeicher für das Band ausgelegt werden. The invention has for its object a device for bright grinding of scaled hot strip, which indicate the grinding process of the scaled Tape in the shortest possible time to the required downtimes of the belt in the inlet section of a continuously operating belt system if possible largely cut. The less time it takes, the smaller one can Buffer for the tape can be designed.
Zur Lösung der Aufgabe wird mit der Erfindung bei einer Einrichtung der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung vorgeschlagen, daß die Schleifeinrichtung mit zwei parallel geführten Endlosschleifbändem ausgestattet ist, von welchen das eine Endlosschleifband mit der Bandoberseite, und zugleich das andere Endlosschleifband mit der Bandunterseite zum Schleifen in Arbeitskontakt bringbar ist.To solve the problem with the invention in a device in the preamble of type mentioned with the invention proposed that the Grinding device equipped with two parallel grinding belts is one of which is an endless sanding belt with the belt top, and at the same time the other endless sanding belt with the underside of the belt for sanding in working contact is feasible.
Eine Ausgestaltung der Schleifeinrichtung sieht vor, daß jedes Schleifband über eine dieses antreibbare Rollenbank gespannt ist.An embodiment of the grinding device provides that each grinding belt over one of these drivable roller banks is excited.
Dabei ist die Schleifeinrichtung derart ausgebildet, daß jede Rollenbank zum Bandschleifen an eine Fläche der Bandoberseite bzw. der Bandunterseite des Warmbandes bei dessen Stillstand mit Schleifkraft anlegbar ist.The grinding device is designed such that each roller bank for Belt grinding on a surface of the upper or lower side of the belt Hot strip can be applied with grinding force at standstill.
Mit Vorteil wird durch das gleichzeitige Schleifen des Warmbandes mittels Endlosschleifbändem von beiden Seiten, d. h. der Bandoberseite und gleichzeitig der Bandunterseite, der Schleifprozeß wesentlich beschleunigt und mit zufriedenstellenden Ergebnis in kurzer Zeit durchgeführt.The simultaneous grinding of the hot strip using endless grinding belts is advantageous from both sides, i.e. H. the band top and at the same time the Underside of the belt, the grinding process is significantly accelerated and satisfactory Result done in a short time.
Eine weitere Ausgestaltung der Schleifeinrichtung sieht vor, daß die Rollenbänke über Führungen miteinander abstandsveränderlich derart verbunden sind, daß ihre Unterstützungsrollen einander gegenüberstehen.Another embodiment of the grinding device provides that the roller banks are connected to one another in a variable manner via guides in such a way that their support roles face each other.
Damit wird verhindert, daß jeder Rolle eine Gegenkraft entgegengesetzt wird und es wird erreicht, daß das Band gleichzeitig von beiden Seiten geschliffen werden kann, ohne daß die Rollen bleibende Verformungen am Band erzeugen. This prevents a counterforce from being opposed to each roller and it is achieved that the belt is ground from both sides at the same time can, without the rollers producing permanent deformations on the belt.
Dabei ist die Schleifeinrichtung quer zur Bandlaufrichtung ausgerichtet. Die Rollenbänke sind über Führungen miteinander verbunden, so daß die Unterstützungsrollen exakt einander gegenüberstehen.The grinding device is aligned transversely to the belt running direction. The roller banks are connected to each other via guides, so that the support roles face each other exactly.
Um bei dieser Anordnung alle Bereiche des Bandes gleichmäßig schleifen zu können, wird die Anordnung der Rollenbänke quer zur Laufrichtung des Warmbandes um eine Strecke entsprechend wenigstens dem Abstand zweier benachbarter Rollen hin- und herfahrbar ausgebildet.To grind all areas of the belt evenly with this arrangement can, the arrangement of the roller banks is transverse to the running direction of the hot strip by a distance corresponding to at least the distance between two neighboring ones Rollers trained back and forth.
Eine Ausgestaltung der Schleifeinrichtung sieht vor, daß die Enden der Rollenbänke über Führungen miteinander abstandsveränderlich verbunden sind, so daß sich zwischen den Rollenbänken ein länglich-rechteckiger Schleifraum ergibt, was dazu führt, daß das zu schleifende Band durch diesen geschlossenen Schleifraum ein- und hindurchgeführt werden muß. Falls dies aus arbeitstechnischen Gründen als nachteilig empfunden wird, sieht die Erfindung in einer weiteren Ausgestaltung der Schleifeinrichtung vor, daß sie in Form an der Vorderseite offenen Gabel mit zwei im parallelen Abstand abstandsveränderlichen Zinken ausgebildet ist, von welchen jeder mit einer ein Endlosschleifband aufweisenden Rollenbank und vorzugsweise mit einer Bandklemmeinrichtung sowie mit Mitteln zur gegenseitigen Abstandseinstellung ausgestattet ist.An embodiment of the grinding device provides that the ends of the roller banks are connected to one another in a variable manner via guides, so that there is an elongated rectangular grinding space between the roller banks, what causes the belt to be ground through this closed grinding space must be introduced and passed through. If this is for technical reasons Is perceived as disadvantageous, the invention sees in a further embodiment the grinder that they are in the open fork shape with two spaced-apart tines formed in parallel distance from which each with a roller bank having an endless grinding belt and preferably with a band clamp and with means for mutual Distance adjustment is equipped.
