Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren sowie auf Einrichtungen zum Benetzen von Bändern, Streifen, Platinen oder dergleichen, insbesondere aus Metall mit einem Schmier mittel, welches über Walzen aufgetragen wird.The invention relates to a method as well as to Devices for wetting tapes, strips, boards or the like, in particular made of metal with a lubricant medium, which is applied over rollers.
Derartige Einrichtungen, wie sie beispielsweise durch das DBP 35 35 479 oder das DE-GM 82 05 070 bekannt geworden sind, sind Umform vorrichtungen, wie Walzvorrichtungen, Stanz- und/oder Zieh vorrichtungen oder dergleichen vorgeschaltet, um z. B. Blechbänder vor der entsprechenden Bearbeitung auf der Ober- und/oder Unterseite mit einem Schmiermittel zu benetzen.Such Facilities such as those found in DBP 35 35 479 or the DE-GM 82 05 070 have become known, are forming devices, such as rolling devices, punching and / or drawing devices or the like upstream to z. B. Sheet metal strips before the corresponding processing on the upper and / or wet the underside with a lubricant.
Der vorliegenden Erfindung lag die Aufgabe zugrunde, die Verteilung des Schmiermittels zu verbessern, die Auftrags schicht zu vergleichmäßigen sowie dünnere Filmschichten auf zutragen und Methoden zu finden, den Einsatz preiswerterer Stoffe zu ermöglichen und somit das Beölen zu verbilligen. Weiterhin soll der Einsatz der Einrichtungen bei Inbetrieb nahme beschleunigt werden.The present invention was based on the object Distribution of the lubricant to improve the order layer to even and thinner film layers to add and find methods of using cheaper To enable substances and thus to make oiling cheaper. Furthermore, the use of the facilities during commissioning be accelerated.
Gemäß der Erfindung wird dies dadurch erzielt, daß das Schmiermittel zum Auftragen beheizt wird.According to the invention, this is achieved in that the Lubricant is heated for application.
Erwärmtes oder erhitztes Schmiermittel ist dünnflüssiger; es kann sich besser und gleichmäßiger verteilen, und es ist möglich, dünnere Schichten auf zutragen, wodurch das Beölen preiswerter wird und wobei auch nach der Umformung des Bleches Kosten gespart werden und die Umwelt geringer belastet wird. Darüber hinaus können hochviskose Öle verwen det werden, die preiswerter sind als die bisher eingesetzten Öle, und wobei doch die oben angeführten Vorteile in gleicher Weise erzielt werden.Heated or heated lubricant is less viscous; it can spread better and more evenly, and it is possible to apply thinner layers, which makes oiling becomes cheaper and even after the forming of the Sheet metal costs can be saved and the environment less is charged. In addition, highly viscous oils can be used which are cheaper than those previously used Oils, and yet the advantages mentioned above in the same Way can be achieved.
Das Auftragen des Schmiermittels kann dadurch erfolgen, daß eine Walze von außen her mit Schmiermittel benetzt und das Schmiermittel oder die Walze beheizt wird, wobei z. B. im Falle der Beheizung der Walze die Beheizung derselben durch Strahlungshitze erfolgen kann.The lubricant can be applied in that wetting a roller from the outside with lubricant and that Lubricant or the roller is heated, z. B. in If the roller is heated, the roller is heated by it Radiant heat can occur.
In vielen Fällen ist es jedoch vorteilhaft, wenn das Auftra gen des Schmiermittels vom Innenraum einer durchlässigen Walze her erfolgt, wobei die Walze selbst und/oder das Schmiermittel selbst beheizbar sein kann. Erfolgt die Beheizung des Öles indirekt, also durch Beheizen der Walze, so können Heizpatronen, Heizdrähte, Heizbänder oder derglei chen an der Außenseite der Walze angelegt oder in Nuten, z. B. Längsnuten der Walze eingelegt sein. Zur Beheizung des Öles können aber auch an der Innenseite der Walze Heizelemente angebracht sein. In many cases, however, it is advantageous if the order lubricant from the interior of a permeable Roll forth here, the roller itself and / or that Lubricant itself can be heated. Does that happen Heating the oil indirectly, i.e. by heating the roller, so cartridge heaters, heating wires, heating tapes or the like Chen created on the outside of the roller or in grooves, z. B. Longitudinal grooves of the roller must be inserted. For heating the oil can also use heating elements on the inside of the roller to be appropriate.
Als durchlässige Walzen können in an sich bekannter Weise solche mit perforiertem rohrförmigem Grundkörper verwendet werden und einen Überzug aus Filz besitzen oder einen Bürstenbesatz aufweisen oder aber auch aus Sintermaterial bestehen, wobei die Schmiermittelzufuhr ebenfalls in an sich bekannter Weise durch eine Hohlachse zugeführt wird.As permeable rollers can be in a conventional manner used with perforated tubular base body and have a felt cover or one Have brush trimmings or made of sintered material exist, the lubricant supply also in itself is supplied in a known manner through a hollow axis.
Es kann, wie bereits erwähnt, hochviskoses Schmiermittel verwendet werden, welches durch die Hohlachse zugeführt und durch das Erhitzen dünnflüssiger wird. Der um die Walze gelegte Filz oder ein ähnliches saugfähiges Material kann das Schmiermittel besser aufsaugen und an das zu benetzende Material abgeben. Es können überaus dünne Schmiermittelfilme erzielt werden, und die Verteilung desselben erfolgt äußerst gleichmäßig. Desgleichen ist die Dosierung exakt einstellbar, und auch geringe Schmiermittelmengen treten gleichmäßig an die Oberfläche. In vielen Fällen sind die Vorteile bei den mit Filz oder dergleichen versehenen Walzen noch ausgeprägter als z. B. bei der Verwendung von Bürstenwalzen, weil Bürsten walzen unter anderem relativ träge auf Mengenänderungen reagieren und bei kleinen Zufuhrmengen eine derart gleichmä ßige Beölung, die mit Filzwalzen nicht möglich ist. Außerdem erfolgt beim Stillstand und Erkalten des Öles das Abtropfen in erheblich geringerem Maße, weil der Filz als Speicher oder Schwamm wirkt, und das Schmiermittel erkaltet und wieder zäher wird, tropft dasselbe nicht. As already mentioned, it can be a highly viscous lubricant are used, which is fed through the hollow axis and becomes thinner by heating. The one around the roller laid felt or a similar absorbent material can do that Better absorb the lubricant and apply it to the one to be wetted Deliver material. Very thin films of lubricant can be used be achieved, and the distribution of the same is extremely evenly. Likewise, the dosage is exactly adjustable, and even small amounts of lubricant occur evenly the surface. In many cases, the advantages are with the rollers provided with felt or the like are even more pronounced as z. B. when using brush rollers because brushes Among other things, they roll relatively slowly on changes in quantity react and such a small amount with small amounts Oiling, which is not possible with felt rollers. Furthermore when the oil comes to a standstill and cools down, it drips to a much lesser extent because of the felt as storage or Sponge works, and the lubricant cools down and again the toughest, the same does not drip.
Wie bereits erwähnt, lassen sich - auch bei der Verwendung von hochviskosen Ölen - dünne Auftragsschichten erzielen, welche wiederum weniger Reinigungsaufwand nach der Umformung des Bleches erfordern, was Kosten einspart und die Umweltbe lastung herabsetzt.As already mentioned, can also be used of highly viscous oils - achieve thin layers, which in turn means less cleaning effort after forming sheet, which saves costs and the environment load reduced.
