Definitions

  • the invention relates to the sawing of stones and marbles, in particular for the extraction of quarries.
  • 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 drilling head was provided with helical series of such plates, fixed by brazing at a significant negative cutting angle of the order of 15 ° and used with a cutting speed of 30 to 40 m / s as used. for grinding wheels.
  • the object of the invention is to use diamond carbide wear plates of the above type on the links of a chain for cutting stones or marbles while eliminating the above drawbacks, that is to say in particular heavy wear, overheating and the high cost of restoring tools.
  • the invention consists in working at low speed, from 1.60 to 3 m / s with a small negative cutting angle of 3 to 6 °.
  • the invention also consists in using diamond plates of circular or polygonal shape with multiple symmetries and in mechanically fixing them in one-piece metal links so that they can easily be rotated on themselves by a certain angle at each tool restoration.
  • the invention also consists in mounting in the cutting chain successive sequences each comprising a large number of different links between them in an evolutionary manner so that the geometric axes of the various plates of these links successively occupy the positions corresponding to generators regularly spaced on a half-cone of revolution having for axis the axis of the chain and for half-angle at the top the aforementioned negative cutting angle of 3 to 6 °, so that each insert only works according to a arc reduced from its periphery.
  • 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 la and lb 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 of 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.
  • a cylindrical shape of revolution is preferably 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 locked in place by a locking plate 6a tightened by a locking screw 7.
  • the links lb and lc are identical in all respects to the links 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 ld, le and lf 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 base.
  • 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 wafer; 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 therefore requires only a small motive force, with as a consequence a slight heating only requiring '' a small amount of cooling water.
  • this cutting speed and the low negative cutting angle an extremely reduced wear is obtained which allows working for whole days without having to stop the saw for restoration.
  • it suffices to unlock the locking screws 7a to 7f and to turn the plates on themselves by a reduced angle corresponds in principle to the common length of the arcs 10a to 10f.
  • the saw chain can be reused, considerably reducing and spacing down time lization, which greatly increases production, and therefore greatly reduces the cost price of m 2 sawn compared to traditional means.
  • 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.
