Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Schleifen der Messer von Zerspanern. Solche Zerspaner dienen dem Zerspanen von Hackschnitzeln zu Spänen, die industriell weiterverarbeitet werden können, beispielsweise als Ausgangsmaterial für Spanplatten. Siehe beispielsweise EP 0 626 234 A2.The invention relates to a device for grinding the knives of Machining. Such chippers are used for cutting wood chips Chips that can be processed industrially, for example as Starting material for chipboard. See for example EP 0 626 234 A2.
Ein großes Problem bei solchen Zerspanern besteht in der relativ geringen Standzeit der Messer. Aufgrund des Verschleißes müssen die Messer bereits nach wenigen Stunden Betriebsdauer ausgetauscht werden, d. h. mehrmals pro Arbeitsschicht. Das Einbauen neuer, scharfer Messer erfordert einen besonderen Aufwand. Die angestrebte Spandicke ergibt sich nämlich aus dem Abstand des Messers gegenüber den sogenannten Verschleißplatten, die ihrerseits Bestandteil des Messerkranzes sind. Daraus folgt, daß das Austauschen stumpfer Messer gegen scharfe Messer sehr Zeit- und kostenaufwendig ist. Insbesondere sind die Personalkosten hierfür hoch.A big problem with such chippers is the relatively small Knife service life. The knives must already be worn be replaced after a few hours of operation, d. H. multiple times per shift. The installation of new, sharp knives requires one special effort. The desired chip thickness results from the distance of the knife from the so-called wear plates, the in turn are part of the knife ring. It follows that the Replacing blunt knives with sharp knives very time and is expensive. In particular, the personnel costs for this are high.
Es ist bekannt, Schleifmessern beim Schleifprozeß ein Kühl- und Schmiermittel zuzuführen, um das Schleifen effizienter zu machen. Dies hat jedoch bisher nicht das gewünschte Ergebnis gebracht. Der Schleifprozeß kann wegen der anfallenden Wärmemenge nur relativ langsam durchgeführt werden.It is known to use a cooling and grinding knives in the grinding process Add lubricant to make grinding more efficient. this has However, so far the desired result has not been achieved. The grinding process can only be carried out relatively slowly due to the amount of heat generated become.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Schleifen der Messer von Zerspanern derart zu gestalten, daß der Schleifprozeß effizienter durchgeführt werden kann.The invention has for its object a device for grinding the To design cutters' knives in such a way that the grinding process becomes more efficient can be carried out.
Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.
Der Erfinder hat erkannt, daß durch die erfindungsgemäße Gestaltung der Schleifvorrichtung das Medium zum Kühlen und zum Schmieren mit hoher Geschwindigkeit an die Arbeitsstelle der Schleifvorrichtung herangeführt wird. Durch die Zentrifugalkraft der Schleifvorrichtung wird nicht nur die Strömungsgeschwindigkeit des Mediums erhöht, sondern auch der Strahldruck des Mediums, so daß dies auch wirklich alle Flächenelemente des zu schleifenden Messers erfaßt. Auf diese Weise läßt sich der Schleifprozeß rascher und effizienter durchführen.The inventor has recognized that the design of the Grinding device the medium for cooling and for lubrication with high Speed is brought up to the working point of the grinding device. Due to the centrifugal force of the grinding device, not only the Flow rate of the medium increases, but also that of Jet pressure of the medium, so that this is really all surface elements of the knife to be grinded. In this way, the grinding process perform faster and more efficiently.
Die Erfindung ist anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.
Fig. 1 zeigt eine Vorrichtung zum Schleifen von Messern eines Zerspaners. Der Zerspaner selbst ist hier nicht dargestellt. Fig. 1 shows a device for sharpening knives of a chipper. The chipper itself is not shown here.
Die Schleifstation 1 ist auf Rollen 1.2 relativ zum Zerspaner verfahrbar, derart, daß ein Messerkorb am Zerspaner in Empfang genommen und von diesem hinwegtransportiert werden kann, zur Arbeitsposition der Schleifstation 1. Im dargestellten Ausführungsbeispiel ist ein Messerkorb 2 in die Schleifstation 1 eingesetzt. Er ruht auf Rollen 1.3, so daß er in der Schleifstation 1 um seine eigene Achse getaktet werden kann.The grinding station 1 can be moved on rollers 1.2 relative to the chipper, in such a way that a knife basket can be received at the chipper and transported away from it to the working position of the grinding station 1 . In the exemplary embodiment shown, a knife basket 2 is inserted into the grinding station 1 . It rests on rollers 1.3 so that it can be clocked about its own axis in the grinding station 1 .
Der Messerkorb 2 weist eine Vielzahl von Messerpaketen 3 auf, die am besten aus Fig. 4 erkennbar sind. Man sieht dort jeweils einen Tragklotz 3.1, eine Klemmplatte 3.2, ein zwischen diesen beiden befindliches Messer 3.3, eine Spannschraube 3.4 sowie eine Verschleißplatte 3.5.The knife basket 2 has a multiplicity of knife packs 3 , which can best be seen from FIG. 4. One can see there a support block 3.1 , a clamping plate 3.2 , a knife 3.3 located between these two, a clamping screw 3.4 and a wear plate 3.5 .
Das entscheidende Element der gesamten Vorrichtung ist eine Schleifeinrichtung 4. Diese ist aus Fig. 1 erkennbar, aber noch genauer aus Fig. 2.The decisive element of the entire device is a grinding device 4 . This can be seen from FIG. 1, but more precisely from FIG. 2.
Die Schleifeinrichtung 4 ist im wesentlichen topfförmig. The grinding device 4 is essentially cup-shaped.
Wie man aus Fig. 2 und Fig. 3 erkennt, weist die Schleifeinrichtung 4 einen Adapter 1, eine Schleifscheibe 4.2 und einen daran angesetzten Schleifring 4.3 auf.As seen from Fig. 2 and Fig. 3, the grinding device 4 to an adapter 1, a grinding wheel 4.2 and a slip ring attached thereto 4.3.
Der Schleifring 4.3 liegt an einem Messer 2.1 an, dessen Schneide geschliffen wird.The slip ring 4.3 rests on a knife 2.1 , the cutting edge of which is ground.
Dem Adapter 4.1 ist eine Leitung 5.2 zum Heranführen eines Kühl- und Schmiermediums zugeordnet. Man erkennt einen Kanal, der aus den Kanalabschnitten 5.2 im Adapter 4.1 und 5.3 in der Schleifscheibe 4.2 zusammengesetzt ist. Hierdurch wird Medium von einem radial innenliegenden Punkt radial nach außen auf die Schneide des Messers 2.1 geleitet.A line 5.2 for introducing a cooling and lubricating medium is assigned to the adapter 4.1 . A channel can be seen which is composed of the channel sections 5.2 in the adapter 4.1 and 5.3 in the grinding wheel 4.2 . As a result, medium is guided radially outward from a point lying radially inward onto the cutting edge of the knife 2.1 .
Zur Erhöhung des Druckes sind mehrere Schaufeln 5.4 vorgesehen. Diese dienen der Druckerhöhung.Several blades 5.4 are provided to increase the pressure. These serve to increase the pressure.
Es versteht sich, daß sich die erfindungsgemäße Vorrichtung nicht nur zum Schleifen von Messern eines Zerspaners, sondern auch von anderen Teilen, beispielsweise von Verschleißplattern eines Zerspaners, einsetzen läßt.It is understood that the device according to the invention is not only for Grinding knives of a chipper, but also of other parts, for example, wear plates of a chipper can be used.
