Definitions

  • the invention relates to a method and a chain for sawing stones or the like according to the respective preambles of claims 1 and 2.
  • wear pads consisting of a tungsten carbide base on which is directly formed, by the application of high pressure and high temperature, a layer of synthetic diamond. Such wear pads give extremely interesting results in the working of metals and even relatively abrasive composite materials.
  • the drill head was provided with helical series of such patches, bonded by brazing at an angle of substantial negative rake of about 15 1 and used with a cutting speed of 30 to 40 m / s as in used for grinding wheels.
  • the object of the invention is to use diamond-tipped carbide wear plates of the preceding type on the links of a chain for cutting stones or marbles while working at a low speed and eliminating the above drawbacks. that is to say in particular the significant wear, overheating and the high cost of restoring the tools.
  • the saw chain shown in fig. 1 is of a conventional design, as well as its drive and its guidance which have not been shown. It includes in particular an alternation of tool-carrying links such as 1 a and 1 b joined together by connecting links 2 in the form of a double yoke of a conventional embodiment.
  • Each of the tool-carrying links is made up of a single piece of steel.
  • this one-piece piece comprises a body 1a, extended at each end by a narrower tab 3a for articulation with the links 2, and surmounted by a cutting head 4a carrying a cutting insert. 5a.
  • This plate 5a has a tungsten carbide base covered on its upper working face by a layer of diamond. It can in particular be constituted by the product manufactured by the General Electric Company and sold under the brand name STRATAPAX. Preferably, a cylindrical shape of revolution is chosen, which allows its mechanical fixing in the head 4a by practicing in the latter a cylindrical counterbore opening at the periphery and in which the plate 5a is exactly embedded, and the latter is found locked in place by a locking plate 6a tightened by a locking screw 7.
  • the links 1b and 1c are identical in all respects to the links 1a except that their plates 5b and 5c are respectively offset slightly to the right for one and to the left for the other.
  • the links 1 d, 1 and 1 f are also identical to the previous ones except that they each have two counterbores to receive two plates respectively 5d to 5f, which are arranged symmetrically and move away from each other gradually while approaching the based.
  • the shape of their heads 4b to 4f and of their clamping plates 6d to 6f naturally evolves accordingly.
  • the nine diamond plates in each sequence of six links are preferably all identical and have been assigned a corresponding index only to refer to their respective positions.
  • each of the nine inserts works only with a limited arc and with a negative cutting angle of 3 to 6 °.
  • This double result is obtained by ensuring that the geometric axis of each insert, that is to say consequently the axis of the corresponding cylindrical counterbore in the head of the corresponding link, meets the axis of the chain, and this at a constant distance from the plate; on the other hand the angle of offset of each of these axes with respect to the previous one around the axis of the chain is also constant.
  • the chain thus formed is driven at a relatively low linear speed of 1.60 to 3 m / s; which consequently requires only a small driving force, with as a consequence a weak heating not requiring only a small quantity of cooling water.
  • this cutting speed and the low negative cutting angle extremely reduced wear is obtained which allows working for whole days without having to stop the saw for restoration.
  • the half-cone of revolution exposed above could have a more flattened configuration in the direction of advance, and be for example semi-elliptical, by distributing the successive spacings of the axes on this cone so as to have arcs cutting lengths of substantially equal length.

Claims (3)

1. Verfahren zum Sägen von Steinen und dergleichen mit Hilfe einer Kettensäge, die mit angesetzten Schneidplättchen (5a bis 5f) aus Wolframkarbid versehen ist, die jeweils in einem Hohlraum entsprechenden Querschnitts derart mechanisch arretiert (6a bis 6f, 7) sind, dass das Plättchen nach dem Entarretieren zum Vergleichmässigen des Verschleisses um einen geeigneten Winkel verdreht werden kann, dadurch gekennzeichnet, dass die Kette hintereinanderliegende, jeweils eine grössere Zahl von Kettengliedern (1 a, 2, 1 b, 2, ... 1f, 2) umfassende Folgen von Kettengliedern aufweist, dass die geometrischen Achsen (8a bis 8f) der verschiedenen Plättchen und infolgedessen auch der zugehörigen Hohlräume so verlaufen, dass diese Achsen die Kettenachse (9) in gleichbleibendem Abstand von dem zugeordneten Plättchen treffen, dass jede dieser Achsen gegenüber der Achse des vorangehenden Kettengliedes um die Kettenachse um einen immer gleichbleibenden Winkelbetrag verschwenkt ist, dass die Schneidflächen der Plättchen in an sich bekannter Weise an Ort und Stelle mit synthetischem Diamant belegt werden, dass die Plättchen so angeordnet sind, dass sich ein negativer Schnittwinkel von 3 bis 6° ergibt, und dass die Plättchen die Form eines Rotationszylinders oder eines polygonalen Prismas mit Mehrfachsymmetrie aufweisen.
2. Kettensäge für Steine oder dergleichen, zur Ausübung des Verfahrens nach Anspruch 1, mit hintereinanderliegenden Kettengliedern (1a, 2, 1 b, 2, ... 1f, 2), von denen mindestens einige (1 bis 1 f) Schneidplättchen (5a bis 5f) tragen, wobei jedes plättchentragende Kettenglied (1 a bis 1 f) als einheitliches massives Teil ausgebildet ist und einen Werkzeughalter (4a bis 4f) besitzt, in den mindestens ein Hohlraum geschnitten ist, der eines der Schneidplättchen (5a bis 5f) aufnimmt und sich zum Aussenrand hin öffnet, um zumindest den Schneidbogen dieses Plättchens freizugeben, und wobei eine Druckplatte (6a bis 6f) und eine Arretierschraube (7) die Arretierung des Plättchens oder der Plättchen in dem zugehörigen Hohlraum ermöglichen, dadurch gekennzeichnet, dass die Hohlräume kreisförmig oder polygonal geformt sind, und dass die Achsen (8a bis 8f) dieser Hohlräume auf die Achse (9) der Kette unter dem erwähnten negativen Schnittwinkel von 3 bis 6° treffen.
3. Kettensäge nach Anspruch 2, dadurch gekennzeichnet, dass hintereinanderliegende Folgen von Kettengliedern (1 a bis 1 f) von sich wandelnder Form vorgesehen sind, und dass die geometrischen Achsen (8a bis 8f) der verschiedenen Plättchen oder Hohlräume, wenn man sie sich als durch Verschiebung längs der Kettenachse zurückgeführt auf ein bestimmtes Kettenglied vorstellt, als gleichmässig von.einander entfernt liegende Erzeugende (8, 9) eines Rotationshalbkegels angeordnet sind, dessen halber Spitzenwinkel gleich dem erwähnten negativen Schnittwinkel von 3 bis 6° ist.
