Description

Vorrichtung zur Abstützung eines Schleifbandes Die Erfindung betrifft eine Vorrichtung zur Abstützung eines Schleifbandes mittels einer gelochten, mit einer Überdruckkammer verbundenen Stützplatte zur Zuführung eines Gleitmittels zwischen Schleifband und Stützplatte.Device for supporting an abrasive belt The invention relates to a device for supporting a grinding belt by means of a perforated, with a pressure chamber connected support plate for supplying a lubricant between Sanding belt and backing plate.

Bei den bekannten Vorrichtungen dieser Art sind die Lochungen der Stützplatte an der Auflaufstelle des Schleifbandes auf die Stützplatte angeordnet. Es wird ein flüssiges Medium durch die Lochungen zwischen die Oberfläche der Stützplatte und die Unterseite des Schleifbandes gepreßt. Zusätzlich wird hierbei noch ein Kühlschmierstoff durch Düsen auf die Oberfläche des Schleifbandes gesprüht.In the known devices of this type, the holes are the Support plate arranged at the point where the sanding belt runs onto the support plate. A liquid medium is drawn through the perforations between the surface of the support plate and pressed the underside of the sanding belt. In addition, a cooling lubricant is used here sprayed through nozzles onto the surface of the sanding belt.

Im Gegensatz hierzu wird nach der Erfindung als Gleitstoff ein gasförmiges Preßmittel, z. B. Kohlendioxyd, Stickstoff od. dgl., verwendet. Dem gasförmigen Preßmittel kann außerdem Öl in feinverteilter Form oder kolloidaler Graphit, Antischweißzusätze od. dgl. beigemengt werden. Durch diese Maßnahmen wird durch die Einwirkung des gasförmigen Preßmittels das Schleifband gewissermaßen schwebend abgestützt, ein kühles Schleifen erreicht und die Griffigkeit des Bandes sowie seine Lebensdauer beträchtlich erhöht. Durch Anwendung von Schleifbändern, die in bekannter Weise mit Lochungen, Einschnitten, Zungen od. dgl. versehen sind, läßt sich der Kühl-und Schmiereffekt, da die unter Überdruck zugeführten Medien dann zusätzlich durch diese Lochungen hindurchtreten können, noch besonders steigern.In contrast to this, according to the invention, a gaseous lubricant is used as the lubricant Pressing means, e.g. B. carbon dioxide, nitrogen or the like. Used. The gaseous Pressing agents can also contain oil in finely divided form or colloidal graphite, anti-perspiration additives or the like. Be added. Through these measures, the action of the gaseous pressing means, the grinding belt is supported in a floating manner, a cool grinding achieved and the grip of the belt as well as its service life increased considerably. By using sanding belts in a known manner Are provided with perforations, incisions, tongues or the like, the cooling and Lubricating effect, as the media supplied under excess pressure are then additionally carried through them Perforations can pass through, especially increase.

In der Zeichnung ist die Vorrichtung zur Abstützung eines Schleifbandes dargestellt. Hierbei ist das Schleifband mit 1 bezeichnet, die Oberfläche der Vorrichtung, über die das Band unter Einwirkung eines Preßmittels schwebend gleitet, mit 2. Die Stützplatte weist die Überdruckkammer 3 auf und besteht aus einem Oberteil 5, das verschiedene Lochungen 6 aufweist, und einen Unterteil 4. 4 und 5 sind fest aufeinandergepreßt, so daß durch die Dichtfläche 7 ein Austritt des gasförmigen Preßmittels verhindert wird. Letzteres wird durch eine Zuführungsleitung 9 der Überdruckkammer 3 zugeführt. Von dort aus strömt es durch eine größere Zahl von Kanälen 6 in den Kontaktbereich des Bandes 1. Die Kanäle 6 können noch Erweiterungen 8 aufweisen, die es ermöglichen, die schwebende Abstützung besonders günstig zu beeinflussen, vor allem bei der Verwendung von gelochten Bändern.In the drawing is the device for supporting a grinding belt shown. Here the sanding belt is denoted by 1, the surface of the device, over which the belt slides under the action of a pressing means, with 2. Die Support plate has the overpressure chamber 3 and consists of an upper part 5, the has different holes 6, and a lower part 4. 4 and 5 are firmly pressed together, so that the gaseous pressing agent is prevented from escaping through the sealing surface 7 will. The latter is fed to the overpressure chamber 3 through a feed line 9. From there it flows through a large number of channels 6 into the contact area of the band 1. The channels 6 can also have extensions 8, which make it possible to influence the floating support particularly favorably, especially when using of perforated tapes.
