Description

Staubabsaugeeinrichtung an Schleifmaschinen für Blechtafeln -o. dgl. Die Erfindung betrifft eine Starubabsaugeeinrichtung an Schleifmaschinen, wie sie z. B. zur Entfernung des Zunders von Schwarzblechen und zu deren Blankschleifen gebraucht werden, die auif einer urn1aufenden und seitlich hin und her bewegten Planscheibe befestigt sind. Das Wesen der Erfindung besteht darin, daß der Schleifstein als Hohlzylinder von verhältnismäßig geringem Durchmesser ausgebildet und in einer schnellaufenden Hohlwelle eingespannt ist, deren Höhlung durch Öffnungen in ihrer Wand mit einem Sauger in Verbyindung steht, dessen Flügelrad auf der Hohlwelle selbst sitzt. Dadurch wird sofortige Ableitung des Schleifstaubes an der Entstebungsstelle gesichert, seine Auffangung, da er noch gewissen Wert besitzt, in Säcken oder sonstigen Behältern ermöglicht sowie die Anlage verwickelter Rohrleitungen, wie sie bei zentraler Absaugung erfordert werden, vermieden. Außerdem wird durch die Fassung des Schleifzylinders in der hohlen Welle vollsiändige Sicherheit gegen Zerspringen desselben gewährleistet. Bekannt ist die Absaugung an der Entstehungsstelle durch die Schleifvorlage oder den Anschlag für das Werkstück.Dust extraction device on grinding machines for sheet metal -o. like The invention relates to a Starub suction device on grinding machines, such as z. B. for removing the scale from black sheets and their bright grinding are needed that move on a rolling and sideways to and fro Face plate are attached. The essence of the invention is that the grindstone designed as a hollow cylinder of relatively small diameter and in a high-speed hollow shaft is clamped, the cavity through openings in their Wall is connected to a suction cup, the impeller of which is on the hollow shaft itself sits. This means that the grinding dust is immediately discharged at the de-stiffening point secured, its collection, since it still has a certain value, in sacks or something else Containers and the creation of intricate pipelines, as is the case with central Suction required are avoided. In addition, the socket of the grinding cylinder in the hollow shaft complete security against shattering is guaranteed. The suction at the point of origin by the grinding template or is known the stop for the workpiece.

Als Beispiel ist eine Ausführungsform durch Abb. r im -,vagerechten Schnitt und Abb. 2 für Querschnitt durch den Sauger dargestellt. Anordnung und Betrieb der Planscheiben sind, weil bekannt und nicht zur Erfindung gehörig, nur angedeutet.As an example, an embodiment is shown by fig Section and Fig. 2 for a cross section through the suction cup. Arrangement and operation the face plates are only indicated because they are known and do not belong to the invention.

Auf der umlaufenden seitlich hin und her bewegten Planscheibe a ist die zu schleifende Blechplatte b irgendwie befestigt. Sie wird von der Kopffläche des schnellaufenden Schleifzylinders c bestrichen, der in der hohlen Welle d gelagert ist, und an deren vorderern Ende Längsschlitze in der Wandung ein Festspannen des Schleifzylinders durch Anziehen :der auf konischem Gewinde laufenden Muttern e ermöglichen. Dem Verschleiß entsprechend kann der Schleifzylinder vorgeschoben werden. Die Wellenachse ist in bekannter Weise etwas schräg zur Achse der Planscheibenwel'.le angeordnet. Da der Schleifzylinder nur um ein geringes aus der Hohlwelle herausragt, so ist vollständige Sicherheit gegen Zerspringen auch bei hoher Drehzahl gewährleistet. Die hohle Welle ist in den beiden Kugelringlagern f und g gelagert. Den Achsialschub nimmt das Kugeldrucklager 1a auf. Innerhalb des Saugergehäuses o, das einen Teil des Maschinengestelles bildet, sind in der Wandung der Hohlwelle d Öffnungen i angebracht, durch die das Fllügelrad k den Schleifstaub, ihn an der Entstehungsstelle erfassend, absaugt, der dann durch die Öffnung l aus der Maschine austritt und in Säcken oder anderen Behältern aufgefangen werden kann, die in irgendeiner passenden Weise am. Maschinengestell angebracht werden. Zur In- lind Außerbetriebsetzung dienen die Fest- und Losscheiben m und n..The sheet metal plate b to be ground is somehow attached to the rotating faceplate a, which is moved back and forth to the side. It is brushed by the top surface of the high-speed grinding cylinder c, which is mounted in the hollow shaft d, and at the front end of which longitudinal slots in the wall allow the grinding cylinder to be tightened by tightening the nuts e running on the conical thread. The grinding cylinder can be advanced according to the wear. In a known manner, the shaft axis is arranged somewhat obliquely to the axis of the face plate shafts. Since the grinding cylinder only protrudes slightly from the hollow shaft, complete security against cracking is guaranteed even at high speed. The hollow shaft is mounted in the two ball ring bearings f and g. The thrust bearing 1a absorbs the axial thrust. Inside the vacuum cleaner housing o, which forms part of the machine frame, openings i are made in the wall of the hollow shaft d , through which the impeller k sucks off the grinding dust, grasping it at the point of origin, which then exits the machine through opening l and can be collected in bags or other containers which are attached to the machine frame in any suitable manner. The fixed and loose disks m and n are used for inbound shutdown.

PATENTANSPRUCH: Staubabsaugeeinrichtung an Schleifmaschinen für Blechtafeln o. dgl., dadurch gekennzeichnet, daß ein als Hohlzylinder ausgebildeter Schleifstein (c) in einer hohlen Welle (d) mit an einer Stelle durchbrochener Wandung gefaßt ist, durch deren Öffnung (i) ein auf der Hohlwelle selbst befestigtes, von einem Gehäuse am, Lagergestell umgebenes Flügelrad (k) den Schl`eifstajub an der Entstehungsstelle erfaßt und absaugt und so aus der Schleifmaschine herausbefördert. PATENT CLAIM: Dust extraction device on grinding machines for sheet metal or the like, characterized in that a grinding stone (c) designed as a hollow cylinder is held in a hollow shaft (d) with a perforated wall at one point, through the opening (i) of which a self-attached impeller (k), surrounded by a housing on the storage frame, grabs the grinding stick at the point of origin and extracts it and thus transports it out of the grinding machine.
