Description

Es sind an Schleifmaschinen Einrichtungen bekannt, um den Sohleifstraiub abizus!auge:n. Diese Einrichtungen e:ind mit Ader .Maschine auch zum Teil organisch verbunden. Es dsa fernerhin bekannt, auch die beim Schleifen entstehenden -Nebel von Kühlflüssigkeiten, insbesondere wenn, Öl -als Kühlflüssigkeit :benutzt wird, @abzu!sau!gen. Diese Absaugeeinrichtungen sind jedoch so gehalten, idaß sie neben iden Maschinen Aufstellung finden edier daß von einer zentralen Stelle aus die Saugrohre zu :den einzelnen Maschinen geleitet wenden.There are facilities known on grinding machines to the sole hoist abizus! eye: n. These facilities e: ind with vein .Machine also partly organic tied together. It is also known, including the mist that occurs during grinding of coolants, especially if oil is used as coolant: @abzu! sau! gen. However, these suction devices are kept in such a way that they are next to The same machines can be set up from a central point for the suction pipes to: turn the individual machines directed.

Der Nachteil, (der solcher zentralen Absauge einrichtung anhaftet, besteht darin, idraß sich idie Kühlflüssigkeitsnebel nur unvdll!ständig aib!saugen lassen, weil :die Saiugrohre meistens am seitlichen oder hinteren Teil der Schleifscheibenschutzhaube angebracht werden. Ferner .sind bei :einer ,zentralen Abisaugung große Verluste in Iden Leitungen vorhanden. Die Abseugung der Flüssigkeitsnebel geht nur unvollkommen vor sich, weil sie sich zum Teil an denInnenwandungemderRöhren niederschlagen. Die Anlage wirkt auch störend im Betrieb.The disadvantage (which is inherent in such a central suction device, consists in the fact that the coolant mist is only visibly sucked in constantly because: the suction pipes mostly on the side or rear part of the grinding wheel protection hood be attached. Furthermore, there are major losses with: a central suction system present in Iden lines. The suction of the liquid mist is only imperfect in front of you, because some of them are reflected on the inner wall of the tubes. the The system also has a disruptive effect on operation.

Die Ei.nzelaibsaugung .ist @insofern nicht vollkommen, weil das Gerät .in der Nahe oder neftxen der Maschine stehen rnuß und verhältnismäßig viel Platz für. sich beansprucht.The egg suction is not perfect because the device There is a relatively large amount of space near or next to the machine for. claimed.

Gemäß ;der Erfindung all id'ieser Übelstand dadurch beseitigt werden, daß idüe Einrichtung zur Absaugung der Flüssigkeitsnebel in; :dem Ständer .der Maschine selbst untergebracht wind, weil (diese Anordnung die günstigsten Abisaugebediingungen in sieh schließt. .Entgegen der bisherigen Gepflogenheit, ,die Flüssigkeitsnebeil seitlich an der Schleifscheibenschutzhaube abous,augen, erfolgt hier die Absaugung (durch ,im Maschinenbett (angebrachte Kanäle, ,die unterhalb (der Schleifscheibe münden und nach abwärts verlaufen. Durch,die natürliche Schleuderwirkung der Scbleifscheibe wind @dtie Küh1fiü:ssigkeit zum großen Teil nach unten ab, geschleudert. Diese Wirkung wind durch die Schwerkraft sowie einegewisseBlaswirkung unterstützt, die iduroh,die schnelle Drehurig (der Schleifscheibe erzeugt wind. Auf (diese Weise ist es.. möglich, mit einem kleinen Absaupsraggregat auszukommen, Idas in dem Ständer,der Maschine untergeb,nacht wenden kann. Ein Ausführungsibeiispiel :der Erfindung :ist in ,der Zeichnung in Fig. i im Schnitt A-B der Eig. 2 und in Fig. 2 im Grundriß und teilweisen Schnitt dargestellt.According to the invention, all this deficiency can be eliminated by that idüe device for suction of the liquid mist in; : the stand .of the machine even housed wind, because (this arrangement the most favorable Abisaugbedingungen in see closes. Contrary to the previous practice,, the liquid hatchet On the side of the grinding wheel protection hood abous, eyes, the extraction takes place here (through, in the machine bed (attached channels,, which underneath (the grinding wheel open and run downwards. By, the natural centrifugal effect of the grinding wheel wind @dtie Küh1fiü: ssigkeit for the most part downwards, hurled. This effect wind supported by gravity as well as a certain blowing effect, the iduroh, the fast Drehurig (the grinding wheel generates wind. In (this way it is .. possible get by with a small suction unit, Idas in the stand, the machine subordinate, night can turn. An exemplary embodiment of the invention: is in, the Drawing in Fig. I in section A-B of the prop. 2 and in Fig. 2 in plan and in part Section shown.

Aus :in: bekannter Weise angeordnerten Kühl- und gegebenenfalls. auch Spritzflüssigkeftsdüsen i fließt Flüssigkeit ;auf die Schleifscheibe tu im Bereich des Werksdickes b. Die Schleif s heibe a wird von einem haubenartigen Gehäuse c umschlossen, von dessen Unterseite ein Abisaug.ekanail d abzweigt. Dieser führt über einen Filter e zu einem Exhaustor f und von: idiesem zu,einem Luftkanal g im Maschinenfundament, oder einen Awstritts.schlite: h für,die von allen Flüssigkeitsanteilen befreite Luft aufweist. Die idurch Iden Filter e abgeschiedene Flüssigkeit kann von einer Pumpe i zu einer Samm,e#-stel!le zurückgefördert werden.From: in: a known way arranged cooling and possibly. Spray liquid nozzles i liquid also flows; onto the grinding wheel tu in the area of the factory thickness b. The grinding disk a is enclosed by a hood-like housing c, from the underside of which a suction duct d branches off. This leads via a filter e to an exhaustor f and from: i to this, an air duct g in the machine foundation, or an access slide: h for which has air that has been freed of all liquid components. The liquid separated by the filter e can be conveyed back to a collecting point by a pump i.

Wie idie vorstehende Beschreibung erkennen läßt,wind idie Schleuderwirkung ,der Schleifscheibe a :am s.tänksten zwischen (der Stelle, am: ider das Kühlmittel auf die Scheibe auftrifft, und dem untersten Punkt ider Schleifscheibe sein. Sie wird in diesem Bereich wesentlich idurch idie Schwerkraft und den saugenden Luftstrom unterstützt, der idurch idie schnelle Drehung ider Schleifscheibe erzeugt wind'. Infolge dieser Unterstützung und der Kiirze (der Saugleitung ist es möglich, reit einem kleinen Absaugeaggregat auszukommen, das auch einen entsprechend niedrigen; Kraftbedarf auf 'weist und ohne Schwierigkeiten in der Maschine selbst :entengebracht wenden kann.As I can see from the description above, I have the centrifugal effect , the grinding wheel a: at the s.tankest between (the place, at: ider the coolant hits the wheel, and be the lowest point of the grinding wheel. she In this area it is mainly due to the force of gravity and the sucking air flow which I generate wind 'by the rapid rotation of the grinding wheel. As a result of this support and the shortness (of the suction line it is possible to ride get by with a small suction unit that also has a correspondingly low one; Power requirement on 'shows and without difficulties in the machine itself: duck-brought can turn.
