Definitions

  • the present invention relates to diamond wire, including improved coupling means for coupling diamond pellets for cutting stony materials, such as marble, stones, granite, concrete and the like.
  • a diamond wire comprising essentially cutting tools in the form of diamond pellets, which are mounted on a high strength steel cable, is conventionally used.
  • two solutions are used, the first of which provides to attach the diamond pellets, as evenly spaced from one another, depending on the working conditions, by partially embedding said diamond pellets into a plastic or rubber material sheath.
  • the other solution provides to thread the diamond pellets on the cable, said diamond pellets being spaced from one another by spring and spacer elements, operating to absorb working vibrations and holding the diamond pellets, which practically constitute a series of cutting tools, spaced from one another.
  • This second type of assembling is preferred as soft materials such as marbles, limestones, and the like must be cut through or processed, since it allows to optimally discharge the cutting waste materials, with a consequent high working speed, much greater than that of the above mentioned plastic or rubber affixing or attaching methods.
  • the diamond pellets and spring elements, and related spacer elements are not made rigid with the steel cable thereby, if the steel cable breaks, the components supported thereon are projected, because of the comparatively high peripheral working speed, with a corresponding high speed.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a diamond wire including improved means for fixing diamond pellets to said wire, adapted to prevent materials from being projected through the working environment, even if the steel cable is broken.
  • a main object of the present invention is to provide such a diamond wire which can operate with a very high operating speed, thereby greatly reducing the stony material cutting time.
  • Another object of the present invention is to provide such a diamond wire which is suitable to allow an optimum discharging of the removed material, as well as to also provide a dry type of cutting, without the need of necessarily using a wet cutting, as it occurs at present.
  • Yet another object of the present invention is to provide such a diamond wire which, owing to its specifically designed constructional features, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a diamond wire, including improved coupling or attaching means for attaching the diamond pellets to said wire, for cutting stony materials, which can be easily made starting from easily available elements and materials.
  • a diamond wire including improved coupling means for coupling to said wire a plurality of diamond pellets, for cutting stony materials, comprising a steel cable supporting a plurality of diamond tools, characterized in that said wire further comprises restraining means for restraining at respective set positions each said diamond tool.
  • the diamond wire including improved coupling or attachment means for coupling to said diamond wire a plurality of diamond pellets, specifically designed for cutting stony materials, according to the present invention, which has been generally indicated by the reference number 1, comprises a steel strand or cable 2, supporting a plurality of diamond cutting tools 3, constituted by cylindric cutting elements, the so-called diamond pellets, which are made of a diamond material, suitable for providing an abrading operation.
  • each said diamond pellet is supported by a supporting bush element 4, arranged about the cable 2.
  • restraining means are provided for restraining at said position each said individual diamond tool or pellet, which restraining means are formed, according to a preferred embodiment of the invention, by locking ring elements 5 which are made rigid with said steel cable 2 by a crimping operation, thereby axially restrain each individual cutting diamond pellet or tool.
  • the mentioned restraining means comprise a weldment 10, locking said bush element 4 on said steel cable thereby fixedly restraining each said cutting tool, or cutting pellet 3, in said preset or target position.
  • the locking of the cutting tools is herein performed by using a glue material 20, affixing each bush element 4 to the steel cable.
  • the glueing material operates as a structural element to make said bush element rigid with said steel cable and, accordingly, it can comprise an adhesive or any desired plastic materials, such as elastomeric materials, polyurethane, thermoplastic materials having a property of making each individual bush element rigid with said steel cable 2.
  • the steel cable 2 is advantageously preloaded by a twisting of 1, 2 turns for each length linear meter, to cause the individual cutting diamond pellets to be subjected, as they are operated, to a rotary movement about the axis of the wire.
  • each individual diamond pellet is evenly worn through the overall surface thereof, since each said pellet is subjected to a continuous rotary action, during the cutting operation.
  • each cutting tool constituted by said diamond pellets, is affixed to the cable without using spacer spring elements or other spacing elements, thereby, if the cable is broken, no material will be projected to the outside environment.
  • the above disclosed coupling means allow to provide a size reduction between a cutting tool and an adjoining cutting tool, exclusively due to the presence of the cable, thereby greatly facilitating the discharging of the removed materials.
  • the above disclosed approach allows to use, as stated, a dry type of cutting operation with any desired types of materials and, to that end, it is possible to provide a suitable sucking device adapted to immediately remove powder deriving from cutting residues or waste materials, thereby providing a fully ecological and non polluting operation.
  • the diamond wire according to the invention provides a plurality of comparatively large free regions between each individual cutting tools, thereby facilitating the ejection of the processing waste materials, while allowing to achieve very high cutting speeds, i.e. a high m 2 /h ratio.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.
