Abstract
Description
Die vorliegende Erfindung betrifft eine Trennscheibe, insbesondere mit einem Durchmesser für über 500 mm, sowie ein Verfahren zur Herstellung einer derartigen Trennscheibe.The present invention relates to a cutting disc, in particular with a Diameter for over 500 mm, and a method for producing such Cutting disc.
Trennscheiben mit großen Durchmessern werden in der metallerzeugenden Industrie verwendet, wo beispielsweise in Stahlwerken oder Gießereien Brammen getrennt werden. Hierbei ist es günstig, die Scheibenstärke der Trennscheiben möglichst gering zu halten, um die Schnittverluste bei den hochwertigen und teuren metallischen Werkstoffen gering zu halten. Zudem führt eine geringe Scheibenstärke dazu, daß der Leistungsaufwand der Trennmaschine sinkt, wodurch sämtliche mechanischen und elektrischen Komponenten der Trennmaschine bei gleichem Trennergebnis weniger belastet werden.Large diameter cutting discs are used in the metal producing industry used where, for example, in steel mills or foundries slabs separated become. It is favorable, the disc thickness of the cutting discs as low as possible to keep the cutting losses in the high quality and expensive metallic Keep materials low. In addition, a low disk thickness causes the Power consumption of the cutting machine decreases, causing all mechanical and electrical components of the cutting machine with the same separation result less be charged.
Bei der Reduzierung der Scheibenstärke ist man derzeit mit dem Problem konfrontiert, daß die im Verhältnis zu ihrem Durchmesser sehr dünnen Scheiben zum Taumeln neigen. Um dieses Taumeln zu verhindern, wurde einerseits versucht, die Spannflansche im Durchmesser zu vergrößern, um die Trennscheiben radial weiter außen zu stabilisieren. Die Vergrößerung der Spannflansche führt jedoch zu einer Verringerung der möglichen Schnitttiefe sowie zu größeren bewegten Massen.Reducing disk thickness is currently a problem that in relation to their diameter very thin disks to tumble tend. To prevent this tumbling, on the one hand tried, the To increase the clamping flanges in diameter, radially to the cutting discs stabilize outside. The enlargement of the clamping flanges, however, leads to a Reduction of the possible cutting depth and larger moving masses.
Bei einem zweiten Lösungsweg wurde versucht, auf einen ausschließlich metallischen Innenbereich der Trennscheibe außen einen kreisringförmigen Schleifbereich aufzusetzen. Das Problem einer stabilen und dauerhaften Verbindung von metallischem Innenbereich und außenliegendem Schleifbereich konnte bisher jedoch noch nicht zufriedenstellend gelöst werden.In a second approach, an attempt was made to a purely metallic Inside the cutting disc outside a circular grinding area sit up. The problem of a stable and lasting connection of Metallic interior and external grinding area has so far, however not yet be solved satisfactorily.
Aufgabe der vorliegenden Erfindung ist es daher, eine Trennscheibe zu schaffen, die trotz im Verhältnis zum Durchmesser geringer Scheibenstärke stabil läuft, wobei gleichzeitig die Probleme der bekannten Lösungsansätze vermieden werden. Object of the present invention is therefore to provide a cutting disc, the despite being stable in relation to the diameter of a small disk thickness, wherein At the same time the problems of the known approaches are avoided.
Dies wird erfindungsgemäß dadurch erreicht, daß die Trennscheibe seitlich mit Stahlblechen oder Stahlgittern mit einer Mindeststärke von 0,5 mm versehen ist.This is inventively achieved in that the cutting disc laterally with Steel sheets or steel meshes is provided with a minimum thickness of 0.5 mm.
Die seitlich auf die axialen Stirnflächen der Trennscheibe aufgebrachten Stahlbleche oder Stahlgitter führen zu einer großflächigen Verteilung der von den Spannflanschen ausgehenden Einspannkräfte. Da die Stahlbleche oder Stahlgitter radial weiter nach außen reichen als die Spannflansche, wird die Trennscheibe großflächig stabilisiert. Aufgrund der relativ geringen Stärke der Stahlbleche oder Stahlgitter wird jedoch die Schnitttiefe nicht reduziert. Dies gilt insbesondere dann, wenn die Stahlbleche oder Stahlgitter bündig in Vertiefungen in den Seitenflächen der Trennscheibe eingefügt sind, wie dies eine bevorzugte Ausführungsform vorsieht.The steel sheets applied laterally to the axial end faces of the cutting disk or steel grids lead to a large-scale distribution of the clamping flanges outgoing clamping forces. As the steel sheets or steel mesh continues to grow radially outside range as the clamping flanges, the cutting disc is stabilized over a large area. However, due to the relatively low strength of the steel sheets or steel mesh, the Cutting depth not reduced. This is especially true when the steel sheets or Steel grille inserted flush in recesses in the side surfaces of the cutting disc are as a preferred embodiment provides.
Um eine optimale Übertragung der Einspannkräfte sicherzustellen, ist es günstig, wenn die Stahlbleche oder Stahlgitter mit der Trennscheibe verklebt sind. Die Stahlbleche oder Stahlgitter können damit auch die in den Randzonen der Trennscheibe auftretenden Biegebeanspruchungen optimal aufnehmen, sodaß ein Taumeln wirksam unterbunden wird.To ensure optimum transfer of the clamping forces, it is advantageous if the steel sheets or steel mesh are glued to the cutting disc. The steel sheets or steel mesh can thus also in the edge zones of the cutting disc Optionally absorb occurring bending stresses, so that a tumbling effect is prevented.
Für ruhige Rundlaufeigenschaften der Trennscheibe ist es günstig, wenn die Stahlbleche oder Stahlgitter im wesentlichen eine runde Form aufweisen.For quiet concentricity of the cutting disc, it is advantageous if the Steel sheets or steel mesh have a substantially round shape.
Im Sinne einer weiteren Stabilisierung der Trennscheibe kann diese in an sich bekannter Weise mindestens eine Gewebeeinlage aufweisen.In terms of further stabilization of the cutting disc, this can in itself known manner have at least one fabric insert.
Das erfindungsgemäße Verfahren sieht vor, daß die Stahlbleche oder Stahlgitter gemeinsam mit dem Bindemittel, dem Schleifkorn und allfälligen Füllstoffen der Trennscheibe verpreßt und anschließend ausgehärtet werden. Dieses Herstellverfahren ist produktionstechnisch besonders günstig und sichert gleichzeitig einen festen Halt der Stahlbleche oder Stahlgitter.The inventive method provides that the steel sheets or steel mesh together with the binder, the abrasive grain and any fillers of the Cutting disc pressed and then cured. This Production process is particularly favorable in terms of production technology and secures at the same time a firm hold of the steel sheets or steel mesh.
Dieser Halt kann noch weiter verbessert werden, indem die Stahlbleche oder Stahlgitter vor dem Verpressen auf der der Trennscheibe zugewandten Seite mit einem Kleber, insbesondere Epoxikleber, versehen werden. This hold can be further improved by using the steel sheets or Steel grid before pressing on the side facing the blade with a Glue, in particular epoxy glue, be provided.
Weitere Merkmale und Einzelheiten der vorliegenden Erfindung ergeben sich aus der
nachfolgenden Figurenbeschreibung. Dabei zeigt:
Bei der in den Figuren dargestellten Trennscheibe 1 handelt es sich um eine kunstharzgebundene Schleifscheibe. Als Kunstharz werden verschiedene Phenolharze verwendet, durch deren gezielte Auswahl im Zusammenspiel mit der Wahl des Schleifmittels und der Füllstoffe das Schleifverhalten sowie der Härtegrad der Trennscheibe den jeweiligen Erfordernissen angepaßt wird.The cutting disc 1 shown in the figures is a Resin-bonded grinding wheel. As a resin, various phenolic resins used by their targeted selection in conjunction with the choice of Abrasive and the fillers the grinding behavior and the degree of hardness of Cutting disc is adapted to the respective requirements.
Als Schleifmittel werden bevorzugt konventionelle Schleifmittel wie Siliziumcarbid und Korunde eingesetzt. Als Füllstoffe dienen vor allem Festschmierstoffe, beispielsweise Pyrit und Graphit, sowie übliche gepulverte Materialien zur Kunststoffverstärkung wie Kalziumcarbonat oder Glaspulver.As abrasives are preferred conventional abrasives such as silicon carbide and Corundum used. As fillers are mainly solid lubricants, for example Pyrite and graphite, as well as common powdered materials for plastic reinforcement such Calcium carbonate or glass powder.
Der Durchmesser d der Trennscheibe 1 liegt typischerweise zwischen 800 mm und 1800 mm. Die Verhältniszahl von Durchmesser d zu Breite b liegt über 80, vorzugsweise sogar über 100. Diese Verhältniszahl soll aufgrund der vorliegenden Erfindung noch weiter gesteigert werden. Es sei angemerkt, daß die Breite b der Trennscheibe 1 aus Anschaulichkeitsgründen in den Figuren im Verhältnis zum Durchmesser d um ein Vielfaches zu groß gezeichnet ist.The diameter d of the cutting wheel 1 is typically between 800 mm and 1800 mm. The ratio of diameter d to width b is over 80, preferably even over 100. This ratio is due to the present Invention be further increased. It should be noted that the width b of the Cutting disc 1 for reasons of clarity in the figures in relation to Diameter d is drawn many times too large.
Die Trennscheibe 1 weist in den seitlichen Stirnflächen Vertiefungen 3 auf, die sich
über einen Durchmesserbereich des Durchmessers d von 45 % bis 80 % erstrecken. In
die Vertiefungen 3 sind die Stahlbleche oder Stahlgitter 2 im wesentlichen bündig
eingesetzt.The cutting disk 1 has
Die Stahlbleche oder Stahlgitter 2 weisen eine Mindeststärke von 0,5 mm auf und
können bis zu 3,0 mm stark sein, wobei übliche Werte eher zwischen 1,0 mm und 2,0
mm liegen. Die Stahlbleche bilden eine geschlossene Fläche, wogegen unter
Stahlgitter Strukturen verstanden werden, die Ausnehmungen, insbesondere
rechteckförmige Ausnehmungen aufweisen. Die Stahlbleche oder Stahlgitter 2 sind mit
der übrigen Trennscheibe 1 verklebt.The steel sheets or
Die Stahlbleche 2 sind beim gezeigten Ausführungsbeispiel rund, wie aus Fig. 3
ersichtlich. Auch wenn die runde Form für ruhige Rundlaufeigenschaften günstig ist,
sind auch beliebige andere Formen, insbesondere Polygonformen, vorstellbar.The
In Fig. 1 sind die beiden zusammenwirkenden Spannflansche 5a und 5b gezeigt, mit
denen die Kraftübertragung auf die Trennscheibe 1 erfolgt. Die Stahlbleche oder
Stahlgitter 2 führen dazu, daß die Krafteinleitung nicht nur auf den Bereich der
Spannflansche 5a und 5b beschränkt bleibt, sondern sich im wesentlichen auf die
gesamte Fläche erstreckt, die die Stahlbleche oder Stahlgitter 2 abdecken. Die
Stabilisierung der Trennscheibe 1 reicht somit radial weit nach außen.In Fig. 1, the two cooperating
In Fig. 2 ist zu erkennen, daß die Trennscheibe 1 eine Gewebeeinlage 6 aulweist. Es handelt sich dabei um ein harzimprägniertes Glasfasergewebe. Die Gewebeeinlage 6 stabilisiert die Trennscheibe 1 und verhindert die Entstehung vagabundierender Scheibenbruchstücke bei einem Versagen der Scheibe. Die vorliegende Erfindung erlaubt es, mit nur einer oder zumindest wenigen Gewebeeinlagen 6 auszukommen. Vorstellbar ist auch eine Ausführungsvariante ohne Gewebeeinlage. Dies ist insofern vorteilhaft, als bei Reduktion der Gewebeschichten das Volumen des Gewebes durch Schleifkom ersetzt werden kann, wodurch die Schleifeigenschaften verbessert werden.In Fig. 2 it can be seen that the cutting disc 1 aullege a fabric insert 6. It is a resin-impregnated glass fiber fabric. The fabric insert 6 stabilizes the blade 1 and prevents the formation of stray Slice fragments in case of failure of the disc. The present invention allows to get along with only one or at least a few fabric inserts 6. Also conceivable is a variant without tissue insert. This is insofar advantageous, as in reduction of the tissue layers, the volume of the tissue through Schleifkom can be replaced, whereby the grinding properties are improved.
