Description

Die Erfindung betrifft ein kreisförmiges Sägeblatt gemäß dem Oberbegriff des Anspruchs 1, insbesondere zur Bearbeitung von natürlichem oder künstlichem Steinmaterial, beispielsweise in Form von Betonwänden. Das Sägeblatt weist an seinem Umfang Bearbeitungsmittel wie Schneid- oder Schleifmittel beziehungsweise Kombinationen hiervon auf. Die Schneid- oder Schleifmittel können dabei beispielsweise durch Diamantkörper, Schneidzähne oder einer Kombination aus beidem gebildet sein. An dem Sägeblatt sind wenigstens zwei in einer Umfangsrichtung aufeinander folgende Sektoren mit jeweils einem axialen Planlaufabweichungsbereich ausgebildet, wobei die aufeinander folgenden Planlaufabweichungsbereiche der Sektoren hinsichtlich einer Mittelebene des Stammblattes zu unterschiedlichen Seiten hin gerichtet sind.The invention relates to a circular saw blade according to the preamble of claim 1, in particular for processing natural or artificial stone material, for example in the form of concrete walls. The saw blade has at its periphery processing means such as cutting or abrasive or combinations thereof. The cutting or abrasive means may be formed for example by diamond body, cutting teeth or a combination of both. On the saw blade at least two successive in a circumferential direction sectors are each formed with an axial Planlaufabweichungsbereich, the successive Planlaufabweichungsbereiche the sectors are directed with respect to a median plane of the master blade to different sides.

Derartige Sägeblätter werden über eine Zentralbohrung an der Werkzeugaufnahme eines entsprechenden Werkzeuggerätes festgelegt und von diesem im Betrieb in Rotation versetzt.Such saw blades are determined via a central bore on the tool holder of a corresponding tool device and offset from this in operation in rotation.

Aus der EP 1 270 126 A1 ist ein kreisförmiges Sägeblatt mit einer Trägerscheibe bekannt, an deren Umfang Schneidelemente angeordnet sind. Ferner sind an den Seitenflächen der Trägerscheibe besonders abriebsfeste Bereiche vorgesehen. Diese verhindern im Betrieb ein durch Reibung hervorgerufenes übermässiges Aufheizen und eine daraus resultierende Verformung des Sägeblattes, die zu einem ungenauen Schnitt führt. Nachteilig an dem bekannten Sägeblatt sind die relativ hohen Materialkosten.From the EP 1 270 126 A1 is a circular saw blade with a carrier disc known, on the circumference of cutting elements are arranged. Furthermore, particularly abrasion-resistant areas are provided on the side surfaces of the carrier disk. These prevent in operation caused by friction excessive heating and a resulting deformation of the saw blade, which leads to an inaccurate cut. A disadvantage of the known saw blade are the relatively high material costs.

Die US 2002/123302 A1 offenbart ein kreisförmiges Sägeblatt mit Zähnen, die entlang des Umfangs angeordnet sind und an der Spitze ein Bearbeitungsmittel aufweisen. Das, Sägeblatt ist nicht eben ausgebildet, sondern weist eine serpentinenähnlich gewundene Form auf. Diese Form des Sägeblattes erzeugt eine grössere Schnittstärke und sorgt dafür, dass der Bearbeitungsstelle mehr Luft zugeführt wird. Ein serpentinenähnlich gewundenes Sägeblatt wird als vorteilhaft beschrieben für Schnitte, bei denen viel Material abgetragen wird und eine geringe Genauigkeit ausreichend ist. Nachteilig an dem bekannten serpentinenähnlich gewundenen Sägeblatt sind die Zunahme der Schnittstärke und damit eine reduzierte Schnittgeschwindigkeit sowie die Ungenauigkeit des Schnittes.The US 2002/123302 A1 discloses a circular saw blade having teeth disposed along the circumference and having a machining means at the tip. The saw blade is not flat, but has a serpentine-like tortuous shape. This shape of the saw blade creates a greater cutting thickness and ensures that more air is supplied to the processing site. A serpentine-like wound saw blade is described as advantageous for cuts in which much material is removed and low accuracy is sufficient. A disadvantage of the known serpentine-like wound saw blade are the increase in the cutting thickness and thus a reduced cutting speed and the inaccuracy of the cut.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einem kreisförmigen Sägeblatt die genannten Nachteile zu vermeiden und bei niedrigen Herstellungskosten einen präzisen Schnitt zu gewährleisten.The present invention has for its object to avoid the disadvantages mentioned in a circular saw blade and to ensure a precise cut at low production costs.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass bei einem Durchmesser des Sägeblattes bis 800 mm wenigstens vier Sektoren mit wechselnden Planlaufabweichungsbereichen vorgesehen sind, wobei die Planlaufabweichungsbereiche eine maximale Planlaufabweichung zwischen 0,1 und 0,2 mm aufweisen, und bei einem Durchmesser des Sägeblattes von mehr als 800 mm wenigstens sechs Sektoren mit wechselnden Planlaufabweichungsbereichen vorgesehen sind, wobei die Planlaufabweichungsbereiche eine maximale Planlaufabweichung zwischen 0,2 und 0,45 mm aufweisen. Die in Umfangsrichtung wechselseitig aufeinander folgenden Planlaufabweichungsbereiche beziehungsweise die dazwischen liegenden Übergangsbereiche sorgen für eine gewisse Aussteifung des Sägeblattes in axialer Richtung. Hierdurch erhält das Sägeblatt im Betrieb eine grössere Seitenstabilität, wodurch ein besonders präziser Schnitt gewährleistet wird. Ferner bewirken die Planlaufabweichungsbereiche einen gewissen Ventilationseffekt, der für eine bessere Kühlung des Sägeblattes sorgt. Hierdurch kann bei längerem Betrieb eine Abnahme der Steifigkeit infolge von Erwärmung des Sägeblattes verringert werden.According to the invention, this object is achieved in that at a diameter of the saw blade to 800 mm at least four sectors are provided with changing Planlaufabweichungsbereichen, wherein the Planlaufabweichungsbereiche have a maximum axial runout between 0.1 and 0.2 mm, and with a diameter of the saw blade of more than 800 mm at least six sectors are provided with alternating runout areas, the runout areas have a maximum runout between 0.2 and 0.45 mm. The circumferentially mutually consecutive plan run deviation ranges or the intervening Transition areas ensure a certain stiffening of the saw blade in the axial direction. As a result, the blade receives in operation a greater lateral stability, whereby a particularly precise cut is guaranteed. Furthermore, the Planlaufabweichungsbereiche cause a certain ventilation effect, which ensures better cooling of the saw blade. As a result, a decrease in rigidity due to heating of the saw blade can be reduced during prolonged operation.

Durch die maximalen Planlaufabweichungen liegen die maximalen Seitenschläge im Bereich der üblichen Toleranzen für die betreffenden Sägeblattgrössen, so dass keine merklich Zunahme der jeweiligen Schnittstärke und damit auch kein merklicher Abfall der Schnittgeschwindigkeit hervorgerufen wird.Due to the maximum runout deviations are the maximum side impacts in the range of the usual tolerances for the respective saw blade sizes, so that no appreciable increase in the respective average thickness and thus no significant drop in the cutting speed is caused.

Bevorzugterweise ist zwischen den maximalen Planlaufabweichungen jeweils zwei benachbarter Sektoren ein Übergangsbereich vorgesehen, in dem der Umfang des Sägeblattes eine monotone Neigung gegenüber der Mittelebene aufweist und der sich in Umfangsrichtung über wenigstens 30° erstreckt. Durch derartige Übergangsbereiche kann eine besonders gute Aussteifung des Sägeblattes in axialer Richtung erzielt werden.Preferably, a transition region is provided between the maximum runout deviations in each case two adjacent sectors, in which the periphery of the saw blade has a monotonous inclination relative to the median plane and extending in the circumferential direction over at least 30 °. By such transition regions, a particularly good stiffening of the saw blade in the axial direction can be achieved.

Vorteilhafterweise weist dabei der Umfang des Sägeblattes eine kontinuierliche Wellenform auf, wodurch trotz der ausgebildeten Seitenschläge im Betrieb ein sehr ruhiger Lauf des Sägeblattes im zu bearbeitenden Material erzielt wird.Advantageously, in this case, the circumference of the saw blade on a continuous waveform, whereby despite the trained side impacts during operation, a very smooth running of the saw blade is achieved in the material to be processed.

Ferner sind die Planlaufabweichungsbereiche vorteilhafterweise durch Beaufschlagung der Seitenflächen des Sägeblattes mit entsprechend gerichteten und energetisch vorbestimmten Schlägen ausgeformt. Auf diese Weise ist eine besonders einfache und kostengünstige Herstellung des Sägeblattes möglich.Furthermore, the runout areas are advantageously formed by applying the side surfaces of the saw blade with appropriately directed and energetically predetermined shocks. In this way, a particularly simple and inexpensive production of the saw blade is possible.

Fig. 1 zeigt ein Sägeblatt 2 zur Bearbeitung von mineralischen Werkstoffen in Form eines Wandsägeblattes mit einem Durchmesser d von bis zu 800mm. Dieses weist ein Stammblatt 4, beispielsweise aus Stahl auf, an dem Bearbeitungsmittel 6 in Form von Schneidzähnen gehalten sind. Die Schneidzähne können dabei einstückig mit dem Stammblatt 4 ausgebildet sein oder wenigstens teilweise aus einem speziellen, auf das Stammblatt 4 aufgebrachten Material gebildet sein. Alternativ zu den Schneidzähnen oder in Kombination mit diesen können am Umfang U des Sägeblattes 2 auch Diamantkörper vorgesehen werden. Dabei können, wie in Fig. 1 durch strichpunktierte Linien angedeutet, beispielsweise Diamantsegmente 7 am Umfang U angebracht sein. Fig. 1 shows a saw blade 2 for machining mineral materials in the form of a wall saw blade with a diameter d of up to 800mm. This comprises a master sheet 4, for example made of steel, are held on the processing means 6 in the form of cutting teeth. The cutting teeth can be integrally formed with the master blade 4 or at least partially formed from a special, applied to the master sheet 4 material. As an alternative to the cutting teeth or in combination with these, diamond bodies can also be provided on the circumference U of the saw blade 2. It can, as in Fig. 1 indicated by dash-dotted lines, for example, diamond segments 7 may be attached to the circumference U.

Zur Befestigung an einer Werkzeugaufnahme eines nicht dargestellten Werkzeuggerätes, dass das Sägeblatt 2 um eine Achse A herum entlang einer Umfangsrichtung rotatorisch antreibt, weist dieses eine Zentralbohrung 8 auf. Ferner teilt sich das Sägeblatt 2 in vier gleich grosse Sektoren S auf, wobei die Sektoren in Umfangsrichtung abwechselnd einen linken Planlaufabweichungsbereich B1 oder einen rechten Planlaufabweichungsbereich B2 aufweisen.For attachment to a tool holder of a tool device, not shown, that rotates the saw blade 2 about an axis A along a circumferential direction, the latter has a central bore 8. Further, the saw blade 2 is divided into four equal sectors S, wherein the sectors in the circumferential direction alternately have a left runout deviation range B1 or a right runout deviation range B2.

In Fig. 2 ist das Sägeblatt 2 zum leichteren Verständnis mit überhöhten Planlaufabweichungsbereichen B1, B2 und ohne Bearbeitungsmittel 6 dargestellt. Wie hieraus zu entnehmen ist, erstrecken sich die Planlaufabweichungsbereiche B1 und B2 weg von einer senkrecht zur Achse A aufgespannten Mittelebene E. Dabei bilden alle Planlaufabweichungsbereiche B1 und B2 einen maximalem Seitenschlag M1, M2 aus, der sich von der Mitte einer Umfangsfläche F des Umfangs U bis zur Mittelebene E erstreckt und zwischen 0,1 und 0,2 mm, insbesondere 0,125 mm, beträgt.In Fig. 2 the saw blade 2 is shown for easy understanding with excessive plan run deviation ranges B1, B2 and without processing means 6. As can be seen therefrom, the axial runout regions B 1 and B 2 extend away from a center plane E spanned perpendicularly to the axis A. In this case, all runout deviation regions B 1 and B 2 form a maximum side impact M 1, M 2, which extends from the center of a peripheral surface F of the circumference U to the center plane E and is between 0.1 and 0.2 mm, in particular 0.125 mm.

Wie aus Fig. 2 ferner zu entnehmen ist, bildet das Sägeblatt 2 am Umfang U zwischen den maximalen Planlaufabweichungen M1, M2 zweier benachbarter Sektoren jeweils einen sich über 90° erstreckenden Übergangsbereich C aus, der gegenüber der Mittelebene E eine wellenförmige monotone Neigung aufweist.How out Fig. 2 can also be seen, forms the saw blade 2 at the circumference U between the maximum runout deviations M1, M2 of two adjacent sectors each extending over 90 ° transition region C, which has a wavy monotone inclination relative to the center plane E.

Fig. 3 und 4 zeigen ein Sägeblatt 2 in Form eines Wandsägeblattes mit einem Durchmesser d der mehr als 800 mm beträgt. Im Gegensatz zur Ausführungsform nach Fig. 1 und 2 sind hier sechs Sektoren S mit Planlaufabweichungsbereichen B1, B2 vorgesehen. Dabei bilden alle Planlaufabweichungsbereiche B1 und B2 einen maximalem Seitenschlag M1, M2 aus, der zwischen 0,2 bis 0,45 mm, insbesondere 0,3 mm, beträgt (siehe Fig.4). Fig. 3 and 4 show a saw blade 2 in the form of a wall saw blade with a diameter d which is more than 800 mm. In contrast to the embodiment according to Fig. 1 and 2 Here six sectors S are provided with runout areas B1, B2. In this case, all of the runout deviations B1 and B2 form a maximum side impact M1, M2, which is between 0.2 to 0.45 mm, in particular 0.3 mm (see Figure 4 ).

Wie aus Fig. 4 ferner zu entnehmen ist, bildet das Sägeblatt 2 bei dieser Ausführungsform am Umfang U zwischen den maximalen Planlaufabweichungen M1, M2 zweier benachbarter Sektoren jeweils einen sich über 60° erstreckenden Übergangsbereich C aus, der gegenüber der Mittelebene E eine wellenförmige monotone Neigung aufweist.How out Fig. 4 can also be seen, forms the saw blade 2 in this embodiment at the circumference U between the maximum runout M1, M2 of two adjacent sectors each extending over 60 ° transition region C, which has a wavy monotone inclination relative to the center plane E.

Die Herstellung der Planlaufabweichungsbereiche B1, B2 erfolgt hierbei durch entsprechende Beaufschlagung des Sägeblattes 2 in Richtung der Achse A mit Schlägen eines nicht dargestellten Werkzeuges, wobei die Schläge eine vorbestimmte Schlagzahl und Schlagenergie aufweisen.The production of the runout deviation regions B1, B2 takes place here by corresponding action on the saw blade 2 in the direction of the axis A with impacts of a tool, not shown, wherein the blows have a predetermined impact number and impact energy.
