Description

"Schleifwerkzeug mit gekühlter Arbeitsfläche Die Neuerung betrifft ein Schleifwerkzeug bzw, eine Scleif= Scheibe mit ,gekilhlter Arbeitsfläche, die für den Rundschliff benutzt wird und dessen Kühlkanäle zur besseren Tufterzeu= gung in gebogener Linie von der Mittelbohrung bis zur Arbeits= fläche verlaufen."Grinding tool with cooled work surface The innovation affects a grinding tool or a grinding disc with a cooled work surface that is used for the round joint and its cooling channels for better Tuftergeneration = supply run in a curved line from the central hole to the work surface.

Bekannt sind Schleifscheiben mit gekühlter Arbeitsfläche bei denen die Kühlkanäle radial vom Umfang der Schleifschei= be bis zur Mittelbohrung in gerader Richtung verlaufen. Grinding wheels with a cooled work surface are known for those the cooling channels radially from the circumference of the grinding wheel to the center hole in a straight line Run direction.

(Deutsche-Patentschrift Nr. 884 oo5). Gerade diese radialen Kühlkanäle in den für Rundschliff benutzten Schleifkörpern haben sich in der praxis als nicht ausreichend erwiesen.Denn der Kühleffekt, der durch die angesogene und wieder ausge= schleuderte uft eintreten sollte, ist in einer Weise erreicht worden.Aus diesem Grunde ist auch auf eine reine Luftkühlung bei Schleifscheiben mit radialen Kanälen von Anfang an ver= zichtet worden. Damit iiberhaunt ein besserer Kbbleffekt gegenüber herkömmlicher Schleifscheiben erzielt wurde,hat man dieses radiale Kühlsystem mit flüssigen Kühlmittel be= schickt. Es hat sich weiter herausgestellt,daß bei Abnutzung r der Schleifscheibe, also bei Veringerung des Schleifscheiben= durchmessers fast kein Kühleffekt mehr vorhanden war. (German patent specification No. 884 oo5). Especially these radial cooling channels in the grinding tools used for circular grinding have proven to be not in practice This has been proven to be sufficient, because the cooling effect created by the sucked in and out again hurled uft should enter has been achieved in a way. From this It is also based on pure air cooling for grinding wheels with radial channels waived from the start. So that a better kbble effect overlooks conventional grinding wheels, you have this radial cooling system with liquid coolant. It has also been found that when worn r of the grinding wheel, i.e. when reducing the grinding wheel diameter = almost there was no longer any cooling effect.

Die Neuerung beseitigt nun diesen Nachteil dadurch, daß die einzelnen Kühlkanäle wie bei einem Kreiselgebläse von der Mittelbohrung ausgehend in einem bestimmten Radius verlaufen und in der Arbeitsfläche der der Schleifscheibe enden. Durch die neue anordnung der Kühlkanäle wird bei richtiger Dreh= richung der Schleifscheibe, die Luftgeschwindigkeit innerhalb dieses Kanalsystems um ein mehrfaches erhöht und damit auch cter Kühleffekt. Auch bei großer Abnutzung der Schleifscheibe können noch Werkzeuge odgl. ohne flüssige Kühlmittel, nur mit der erzeugten Luftkühlung zuverlässig geschliffen werden. Es werden auch somit kleinere Betriebe in der Lage versetzt,ohne den Zusatz von fliissigen Kühlmitteln,nur mit reiner Luftkühlung wirkungsvoll, sauberer und übersichtlicher, Schleifarbeiten aus zuführen. Natürlich kann dieses Kühlsystem besonders vorteil= haft mit flüssigem Kühlmittel beschickt werden, weil die Kühl mitteltemperatur durch die größere Luftgeschwindigkeit konstanter gehalten wird. The innovation eliminates this disadvantage in that the individual Cooling channels like a centrifugal fan starting from the central bore in one run certain radius and end in the working surface of the grinding wheel. Due to the new arrangement of the cooling channels, if the grinding wheel rotates in the correct direction, the air speed within this duct system increased several times and with it also cter cooling effect. Even if the grinding wheel is very worn can still tools or the like. without liquid coolants, only with the air cooling generated be ground reliably. Smaller businesses will also be able to do this added, without the addition of liquid coolants, only effective with pure air cooling, Carry out grinding work in a cleaner and clearer manner. Of course this can Cooling system particularly advantageous = be charged with liquid coolant because the coolant temperature is kept more constant due to the greater air speed will.

Nähere Einzelheiten und Vorteile der Neuerung ergeben sich aus der folgenden Beschreibung des auf der Zeichnung dargestellten Ausführungsbeispieles. Hierbei zeigt: Abb,l den Grundriß einer für Rundschliff benutzten Schleif scheibe Abb. 2 einen Längsschnitt der Schleifscheibe Ibb. 1 mit Tragscheiben.Further details and advantages of the innovation emerge from the following description of the embodiment shown in the drawing. Here: Fig. 1 shows the plan of a grinding wheel used for circular grinding Fig. 2 is a longitudinal section of the grinding wheel Ibb. 1 with support washers.

Die Grundrißdarstellung Abb.1, zeigt Schleifscheibe(1# sowie die durch gestrichelte Linien gekennzeichneten Kühlkanäle (6) .The plan view Fig.1 shows the grinding wheel (1 # as well as the through dashed lines marked cooling channels (6).

Die Kühlkanäle (6), alle beginnend in Bohrung C?) -Z2rlaufren in einem bestimmten Radius zur Arbeitsfläche (8)der Schleifscheibe )1). Die Kühlkanäle (6) sind so angeordnet, daß sie wie die Luftleitbleche in einem Kreiselgebläse verlaufen.Die geförderte Luftmenge kann noch erhöht werden,wenn die Kühlkanäle (6) so gestaltet werden,daF sie an der Bohrung (7) normal beginnen undsich bis zur Arbeitsfläche #8) laufend vergrößern. Weil die Kühlung nur in Pfeilrichtung (a) wirksam wird,ist es zweckmäßig die Schleifscheibe (1) mit einem Pfeil ZU beschildern.The cooling channels (6), all starting in hole C?) -Z2rlaufren in one certain radius to the working surface (8) of the grinding wheel) 1). The cooling channels (6) are arranged so that they run like the air baffles in a centrifugal fan The amount of air delivered can be increased if the cooling channels (6) are designed in this way that they start normally at the hole (7) and extend to the work surface # 8) enlarge continuously. Because the cooling is only effective in the direction of the arrow (a) it is advisable to sign the grinding wheel (1) with an arrow ZU.

In Abb.2 sind die beiden Tragscheiben (2+3) dargestellt,die beiderseitiz in Bohrung (7) die Schleifscheibe (1) aufnehmen und zugleich zentrieren.Wenn die Schleifscheibe (1) in Pfeil= richtung (a) rotiert,tritt die angesaugte Luft durch mehrere Bohrungen oder Ausnehmungen (5) der Tragscheiben (2+3) in den freien Raum (7). Sie wird dann durch die Kühlkanäle (6) gebläse= artig beschleunigt und kommt so an der Arbeitsfläche (8) zur Wirkung.Die Bohrungen oder- Ausnehmungen (5) sind von inden gesenkt bzw. stark abgeschrägt,damit sie beim Rotieren größere Luft= -mengen durchlassen.In Fig.2 the two support disks (2 + 3) are shown, which are on both sides Pick up the grinding wheel (1) in the hole (7) and center it at the same time If the grinding wheel (1) rotates in the direction of the arrow (a), the sucked in air passes through several bores or recesses (5) of the support disks (2 + 3) in the free space (7). It is then accelerated like a fan through the cooling ducts (6) and comes so on the work surface (8) to the effect. The holes or recesses (5) are from inden lowered or strongly beveled, so that they have larger amounts of air when rotating let through.
