Abstract

Saw blades for cutting natural stone have a saw plate (1) which is fitted with diamond-studded cutting segments (2). To increase the cutting capacity of the saw plates (1), the cutting segments (2) are elastically attached to the saw plate (1), in which arrangement either these cutting segments (2) are fastened to a U-shaped flexible stirrup (5) or the fastening location of the cutting segments on the saw plate is of flexible design. A further increase in the stability of the saw blades can be achieved by the cutting segments (2) being of conically tapering design as viewed in cross-section, and in fact with such an angle of taper that the cutting face, rectangular in each case, of the cutting segment is displaced downwards as a result of the wear in such a way that this cutting face retains approximately the same height <IMAGE>

Description

Die Erfindung betrifft ein Sägeblatt, insbesondere diamantbesetzte Sägeblätter zum Schneiden von Natursteinen, bestehend aus einem mit Schneidsegmenten besetzten Stammblatt.The invention relates to a saw blade, in particular diamond-studded saw blades for cutting natural stones, consisting of a master blade covered with cutting segments.

Die Betriebskosten von Sägeblättern werden zum einen von den Anschaffungskosten und zum anderen von der Zerspanungsleistung und der Standzeit der Sägeblätter bestimmt. Es ist bekannt, die Standzeit der Sägeblätter dadurch zu verlängern, daß die Höhe der Schneidsegmente, d.h. der verschleißende Teil dieser Schneidsegmente möglichst hoch gemacht wird. Die Belaghöhe kann jedoch nicht beliebig erhöht werden, da ansonsten ein unzureichender seitlicher Freischnitt und eine ungleichmäßige Abnutzung der Schneidsegmente erfolgt, wodurch diese eine für den Schnitt unvorteilhafte konische Gestaltung erhalten.The operating costs of saw blades are determined on the one hand by the acquisition costs and on the other hand by the cutting performance and the service life of the saw blades. It is known to extend the service life of the saw blades by increasing the height of the cutting segments, i.e. the wearing part of these cutting segments is made as high as possible. However, the covering height cannot be increased arbitrarily, since otherwise there is insufficient lateral free cutting and uneven wear of the cutting segments, which gives them a conical configuration which is disadvantageous for the cut.

Mit Diamantschneidsegmenten bestückte Sägeblätter von 200 - 4.000 mm Durchmesser weisen heute eine Zerspanungsleistung von ca. 4oo cm'/min auf. Die Standzeit der Sägeblätter beträgt bei üblicherSaw blades with a diameter of 200 - 4,000 mm equipped with diamond cutting segments have a cutting performance of approx. 4oo cm '/ min. The service life of the saw blades is the usual

Belaghöhe ca. 600 m2. Aufgabe der Erfindung ist es, die Zerspanungsleistung und die Standzeit von Schneidsegmenten von Sägeblättern, insbesondere von mit Diamenten besetzten Schneidsegmenten wesentlich zu steigern. B elaghöhe about 600 m 2. The object of the invention is to erspanungsleistung the Z and increase the service life of cutting segments of saw blades, especially occupied with Diamenten cutting segments significantly.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst,daß die Schneidsegmente elastisch auf dem Stammblatt aufgebracht sind. Vorteilhaft werden die Schneidsegmente auf U-förmig ausgebildeten Bügeln befestigt, die mit ihren seitlichen Schenkeln am Stammblatt befestigt sind, wobei der mittlere Verbindungssteg einen Abstand zum Stammblatt aufweist. Es ist jedoch auch denkbar, im Stammblatt unterhalb der Befestigungsstellen die Schneidsegmente mit Aussparungen zu versehen, so daß gleichfalls eine elastische Lagerung der Schneidsegmente erfolgt.This object is achieved in that the cutting segments are elastically applied to the base sheet. The cutting segments are advantageously fastened on U-shaped brackets which are attached to the base sheet with their lateral legs, the middle connecting web being at a distance from the base sheet. However, it is also conceivable to provide the cutting segments with cutouts in the base sheet below the fastening points, so that the cutting segments are also elastically supported.

Die elastische Lagerung der Schneidsegmente hat eine Steigerung der Zerspanungsleistung und auch der Standzeit um Werte bis zu je 50 % erbracht, wobei die Belaghöhe jeweils gleich hoch gewählt worden ist. Diese Leistungssteigerung und Erhöhung der Standzeit ist darauf zurückzuführen, daß durch die elastische Lagerung der Schneidsegmente die spröden Diamanten im Schneidbelag erheblich mehr geschont werden, so daß diese bei der stoßartigen Belastung der Schneidsegmente weniger zerschlagen werden. Die Leistung des Sägeblattes ist proportional der im Eingriff stehenden Diamantspitzen. Durch die elastische Lagerung der Schneidsegmente werden die herausragenden und schneidenden Diamantspitzen weniger stark zerschlagen und herausgebrochen, so daß im jeweiligen Augenblick mehr Diamantsegmente im Eingriff stehen und länger genutzt werden können. Die Folge ist eine erheblich gesteigerte Standzeit und Zerspanungsleistung.The elastic mounting of the cutting segments has increased the cutting performance and also the tool life by values of up to 50% each, whereby the covering height has been chosen to be the same. This increase in performance and increase the service life due to the fact that by the elastic mounting of the cutting segments in the brittle diamond S chneidbelag be considerably spared more, so that they are less shatter in shock-like load on the cutting segments. The performance of the saw blade is proportional to the engaged diamond tips. Due to the elastic mounting of the cutting segments, the protruding and cutting diamond tips are less severely broken and broken out, so that at any given moment more diamond segments are in engagement and can be used for longer. The result is a significantly increased tool life and cutting performance.

Die Erfindung kommt insbesondere bei diamantbesetzten Schneidsegmenten zum Tragen, da diese äußerst empfindlich gegen stoßartige Beanspruchungen sind. Die Erfindung kann jedoch auch gleichermaßen bei anderen harten Schneidelementen eingesetzt werden, die in einer Masse eingebettet sind.The invention is particularly useful for diamond-trimmed cutting segments, since they are extremely sensitive against sudden loads. However, the invention can also be used equally with other hard cutting elements which are embedded in a mass.

Im folgenden wird die Erfindung anhand der Zeichnung näher beschrieben, in dieser zeigen:

  • Fig. 2 ein erfindungsgemäß ausgebildetes Sägeblatt, bei dem das Schneidsegment auf einem Bügel befestigt ist,
  • Fig. 3 eine weitere Ausführungsform eines erfindungsgemäßen Stammblattes mit einer Aussparung im Bereich des Schneidsegmentes und
  • Fig. 4 einen Schnitt nach Linie IV-IV in Fig.3.
The invention is described in more detail below with reference to the drawing, in which:
  • 1 is a partial side view of a conventional saw blade,
  • 2 shows a saw blade designed according to the invention, in which the cutting segment is fastened on a bracket,
  • 3 shows a further embodiment of a master blade according to the invention with a recess in the area of the cutting segment and
  • Fig. 4 shows a section along line IV-IV in Fig.3.

In den Fig. 1 bis 3 bezeichnet 1 das Stammblatt von Sägeblättern. Dieses Stammblatt kann einen Durchmesser bis zu drei Metern aufweisen. Auf dem Stammblatt 1 ist bei den bekannten Sägeblättern das Schneidsegment 2 unmittelbar aufgelötet. Die Schneidsegmente 2 bestehen aus einem rechteckförmigen äußeren Teil, deren Höhe etwa 5 mm beträgt und einem sich daran anschließenden, nach innen kegelförmig verjüngenden Teil 4, dessen Höhe etwa 15 mm beträgt, so daß die Höhe des gesamten Schneidsegmentes etwa 20 mm ausmacht. Der Kegelwinkel des kegelförmigen Teils ist so gewählt, daß sich bei fortschreitender Abnutzung der Höhe und der Breite des rechteckförmigen Teiles des Schneidsegmentes die Seitenfläche des rechteckförmigen Teiles 3 derart nach unten verschiebt,daß diese in etwa die gleiche Höhe behält, jedoch ständig zum Stammblatt zuwandert. Hierdurch ist gewährleistet, daß ständig sowohl die erforderliche Seitenführung für das Stammblatt erhalten bleibt wie auch das erforderliche Freischneiden erreicht wird. Hierdurch ist es möglich, die Höhe des Schneidsegmentes so groß zu machen, daß bereits hierdurch eine Erhöhung der Standzeit erreicht wird, ohne daß eine ungleichmäßige Abnutzung und ein Verlaufen des Schnittes zu befürchten ist.1 to 3, 1 denotes the master blade of saw blades. This master sheet can have a diameter of up to three meters. In the known saw blades, the cutting segment 2 is soldered directly onto the master blade 1. The cutting segments 2 consist of a rectangular outer part, the height of which is approximately 5 mm and an adjoining, inwardly tapering part 4, the height of which is approximately 15 mm, so that the height of the entire cutting segment is approximately 20 mm. The cone angle of the conical part is chosen so that as the wear progresses, the height and width of the rectangular part change of the cutting segment moves the side surface of the rectangular part 3 downward in such a way that it maintains approximately the same height, but constantly migrates towards the base sheet. This ensures that both the required lateral guidance for the master blade is maintained as well as the required free cutting is achieved. This makes it possible to make the height of the cutting segment so large that an increase in the service life is achieved in this way without fear of uneven wear and a running of the cut.

Durch diese Maßnahme kann zwar die Standzeit erhöht werden, jedoch ist eine Erhöhung der Schneidleistung durch die geometrische Gestaltung des Schneidsegmentes, wenn überhaupt, nur in sehr geringem Umfange möglich. Gemäß der Erfindung wird jedoch auch die Schneidleistung wie auch die Standzeit eines Schneidsegmentes definierter Höhe bis zu 50 % gesteigert, wenn das Schneidsegment 2 elastisch, d.h. federnd nachgiebig auf dem Stammblatt 1 befestigt ist. Hierdurch wird erreicht, daß die Diamanten des Schneidsegmentes, die aus der Oberfläche desselben herausragen und im Einsatz sind, nicht durch die stoßweise Belastung zersplittert oder aus dem Schneidsegment herausgerissen werden. Bei der herkömmlichen Anordnung der Schneidsegmente wurden etwa lediglich 30.% der.Diamanten zum Schneiden ausgenutzt, während der Rest der Diamanten aus dem Schneidsegment herausgeschlagen wurden. Bei der elastischen Anordnung des Schneidsegmentes wurde gefunden, daß die Diamanten bis zu 70 % für die Zerspanarbeit herangezogen werden konnten, während lediglich noch ca. 30 % zersplitterten oder aus dem Schneidsegment herausgeschlagen wurden.The tool life can be increased by this measure, but an increase in the cutting performance due to the geometric design of the cutting segment is only possible to a very small extent, if at all. According to the invention, however, the cutting performance and the service life of a cutting segment of a defined height are increased by up to 50% if the cutting segment 2 is fastened to the master blade 1 in an elastic, ie resilient, manner. This ensures that the diamonds of the cutting segment, which protrude from the surface of the cutting segment and are in use, are not shattered by the intermittent loading or torn out of the cutting segment. With the conventional arrangement of the cutting segments, only 30 were used . % of the diamonds used for cutting while the rest of the diamonds were knocked out of the cutting segment. With the elastic arrangement of the cutting segment, it was found that the diamonds could be used up to 70% for the cutting work, while only about 30% were still shattered or knocked out of the cutting segment.

Diese elastische Lagerung der Schneidsegmente 2 auf dem Stammblatt 1 kann entweder, wie dies in Fig. 2 dargestellt ist, dadurch-erfolgen, daß die Schneidsegmente 2 auf einem U-förmig ausgebildeten Bügel 5 aufgelötet werden, dessen Schenkel 6, 7 ihrerseits mit dem Stammblatt 1 fest verbunden sind. Der die Schenkel 6, 7 verbindende Steg 8 weist einen ausreichenden Abstand zur Oberkante 9 des Stammblattes auf, so daß das Schneidsegment 2 einen ausreichenden Federweg erfährt. Die Elastizität des Bügels kann zum einen durch die Wahl der Stärke des Bügels 8 und zum anderen gleichfalls durch die Höhe der Schenkel 6, 7 bestimmt werden.This elastic mounting of the cutting segments 2 on the base sheet 1 can either, as shown in FIG. 2, take place in that the cutting segments 2 are soldered onto a U-shaped bracket 5, the legs 6, 7 of which in turn with the base sheet 1 are firmly connected. The web 8 connecting the legs 6, 7 is at a sufficient distance from the upper edge 9 of the main blade, so that the cutting segment 2 experiences sufficient spring travel. The elasticity of the bracket can be determined on the one hand by the choice of the thickness of the bracket 8 and on the other hand by the height of the legs 6, 7.

Bei dem Ausführungsbeispiel nach Fig. 3 ist das Schneidsegment 2 in herkömmlicher Weise unmittelbar auf das Stammblatt 1 aufgelötet. Allerdings weist dieses Stammblatt 1 unterhalb eines jeden Schneidsegmentes 2 eine Aussparung lO auf, die sich zumindest über die Breite des Schneidsegmentes 2 erstreckt. Hier wird die federnde Lagerung des Schneidsegmentes 2 durch die Breite der Aussparung lO und durch die Höhe des verbleibenden Steges 11 des Stammblattes 1 bestimmt.In the exemplary embodiment according to FIG. 3, the cutting segment 2 is soldered directly onto the master sheet 1 in a conventional manner. However, this master sheet 1 has a cutout 10 below each cutting segment 2, which extends at least over the width of the cutting segment 2. Here, the resilient mounting of the cutting segment 2 is determined by the width of the recess 10 and by the height of the remaining web 11 of the master blade 1.

In Fig. 4 ist ein Schnitt durch Fig. 3 dargestellt, der die Anordnung des Schneidsegmentes 2 auf dem Stammblatt 1 zeigt. Bei geeigneter Wahl der Elastizität des Schneidsegmentes auf dem Stammblatt 1 kann, wie die Versuche gezeigt haben, eine Erhöhung der Standzeit um 50 % und der Zerspanungsleistung gleichfalls um 50 % bei gleicher Schneidsegmenthöhe 2 erhalten werden. Hierdurch läßt sich die Wirtschaftlichkeit der Sägeblätter, insbesondere der mit Diamantspitzen besetzten Sägeblätter, in erheblichem Umfange erhöhen. Die Erfindung ist jedoch gleichermaßen auch für Sägeblätter geeignet eingesetzt zu werden, bei denen zum Schneiden nicht Diamanten, sondern andere spröde, harte Körper dienen.FIG. 4 shows a section through FIG. 3, which shows the arrangement of the cutting segment 2 on the master sheet 1. With a suitable choice of the elasticity of the cutting segment on the main blade 1, as the experiments have shown, an increase in the tool life by 50% and the cutting performance by 50% can be obtained with the same cutting segment height 2. As a result, the cost-effectiveness of the saw blades, in particular those with diamond tips, can be increased to a considerable extent. However, the invention is equally suitable to be used for saw blades in which not diamonds, but other brittle, hard bodies are used for cutting.
