Definitions

  • the present invention refers to a cutting device, especially to a cutting machine of multithreading wires with diamond pearls to cut blocks of natural or artificial stone.
  • processes for cutting into sheets of 2 cm or other thicknesses are made with diamond wire or multiwire saw machines, which use 10, 15, 20 or up to 100 wires of diamond cut, that can be of 5mm, 6mm and 7.2 mm of diameter. They usually have from 23 to 25 linear meter of development, and generally consist of a laminated and closed steel wire with 35 to 37 diamond pearls per meter.
  • control pulleys usually have 2000 mm of diameter, tension pulleys 800 mm and guidance and support pulleys 400 mm resulting in elements with high maintenance cost and susceptible to mechanical and cutting failures, due to the fact that a failure of a cutting element (wire) leads to the possibility of failuresof several further elements. Due to the aforementioned characteristics the possibilities of the variation of the cutting thickness of the material are very limited.
  • each ring takes place, in the prior art, by the adjustment of the position of the pulleys or of the return drum, subdivided to this end into individual pulleys, separated with each other by the distance at which the diamond wires should work, to cut the slabs into the requested thickness.
  • Tension devices of the diamond wires in which the tension pulleys that act over the wires alternated in the return or backflow branches in the annular path that act radially, pushing or pulling, over an only wire so that tension is produced in all the wire are known. In this case, however, the devices act in at least two branches or different points in the path of the wires.
  • the tensioning is subdivided into two devices, one for the displacement of the pulleys for major adjustments, as in the case of substitution of one or more diamond wire rings and another for the fine adjustment of the unique wire tension.
  • the tensioning exercised requires the use of the pulleys or wheels that do not have a great diameter, preventing this way very big dimensions of the machine, to jeopardize the winding of the wire, the life and the duration of the wire itself. Therefore, the diamond wire needs drums, wheels or pulleys that have diameters equal or bigger than one meter to have an acceptable average life.
  • the steel wire that supports the diamond inserts is bended every time it comes into flexion with a wheel, pulley or drum and with it makes a short rotation arch.
  • the above- mentioned guidance rollers can be supported over the support structure of the actuation roller and move with it, or over said translation part of the tension device.
  • the reduction in the number of contacts of the wire closed in a ring in its path always leads to an improvement in the duration (life) of the diamond wire.
  • WO 2012/143956 Al that includes a frame device, formed by 5 pulleys, 1 oversize engine flywheel, 4 of them are tensors individually over each axis (description of the WO: in which the support of the cutting diamond wires for its tensioning is distributed in four support points, two in the guidance rollers, but present in the upper entrance and lower exit branches of the wire tensioning device, and two in individual pulleys for each diamond wire, of the tensor device, supported over a translation part thereof, with respect to which in turn cause the support and tensioning pulleys of the unique wire oscillate independently regarding the translation part of the tensor device).
  • the document CN105263658A is also known, that includes a frame device, composed of 10 flywheels, 2 of the flywheels correspond to individual horizontal tensors over each cutting element (wires), 2 of the flywheels correspond to guides, placed at the lower ends, 1 of the flywheels of major diameter corresponds to the motor axis.
  • the patent EP1598162A1 that claims a frame device, composed of 9 flywheels, 3 of which are individual tensors over each cutting element (wire), 1 engine flywheel. It allows the variation of cutting thicknesses but only in predefined values.
  • the document WO2009098721A1 that describes a frame device,composed of 4 pulleys, 1 oversize engine flywheel, 1 of them is individually tensor over each axle.
  • the patent WO2011033541 Al refers to a frame device, composed of 5 pulleys, 1 oversize engine flywheel, 2 of which are guidance flywheels and are located coplanar in the lower end of the device, 1 of them is individually tensor over each axis.
  • the document WO2015198281 Al that claims a frame device, composed of 4 pulleys plus 4 additional guides, 1 engine flywheel, 2 tensioning flywheels.
  • patent WO2016071936A1 that includes a frame device, composed of 6 pulleys, 1 oversize engine flywheel, 1 free pulley ,2 guidance pulleys, 2 tensor flywheels.
  • support, tension and rotation devices are known, that are complex, that is, are formed by a great number of parts, with high costs and/or high maintenance, that also include the time used in the assembly and disassembly of the parts of the devices; both in the ordinary maintenance and in the replacement of the diamond wire rings, and in the extraordinary maintenance such as the substitution or repartition of parts of the device.
  • Most expensive maintenance operations are the substitution of the bearings of the tensioning pulleys or of the non-metallic material to cover the slots of the wheel or drum to transmit the cutting movement.
  • a premature wear of the plastic coating material of the pulleys and bearings causes an excessive dead time of replacement of cutting parts and supplies (that must be recovered) and requires highly skilled workforce to guarantee the optimum operation and profitability of the equipment.
  • Said state of the art is susceptible of significant improvements regarding the possibility of overcoming the before-mentioned inconveniences and to make a multiwire machine to cut blocks of natural or artificial stones with the profitability characteristics intrinsically associated with the parts of the machine used.
  • the technical problems described herein are solved,according to the present invention, with a multiwire machine to cut blocks of natural or artificial stones, that reduces to a minimum the length of the cutting wires and uses a lesser amount of pulleys (2), which leads to a lower cost of maintenance due to savings of the mobile parts (bearings) and plastics coatings (and the saving when avoiding said parts), at the same time a lower electricity consumption is achieved, since there are less kilos that require to be moved per diamond wire (saving 80% in costs of maintenance compared to any similar machine).
  • the present invention refers to a cutting machine for multithreading wires with diamond pearls to cut blocks of natural or artificial stone that includes a command and control pulley associated to an engine, related to a second tension pulley that is attached to a pneumatic arm, that acts over the entirely of the pulley and cutting wires; over each pulley protection bands are installed, over which the steel wires are tensioned with diamond pearls; both pulleys are linked between them with the steel wires with diamond pearls, arranged in a confined cut ring shape.
  • Figure 1 is a schematic view in perspective of the cutting machine object of the present invention wherein a control and command pulley can be seen associated to a height adjustable engine, related to a second tension pulley that is attached to a pneumatic arm, in relation to each other with steel wires with diamond pearls, arranged in a confined cut ring shape.
  • Figure 2 shows a back view in perspective of the cutting machine object of the present invention, wherein the control and command pulley can be seen associated to an engine and a pneumatic arm.
  • Figure 3 represents a front view of the cutting machine object of the present invention, wherein pulleys can be seen arranged in a confined cut ring shape.
  • Figure 4 is a back view of the cutting machine object of the present invention, wherein the pneumatic arm can be seen and wherein pulleys can be seen arranged in a confined cut ring shape.
  • the object of the present invention is, therefore, a cutting machine for wires with diamond pearls to cut blocks of natural or artificial stone.
  • the following paragraphs include an accurate description of one preferred embodiment, making reference to the enclosed illustrative drawings, everything by way of explanatory example but not limited to, and which components can be selected among different equivalents without departing from the principles established in the present document.
  • Said machine includes a control and command pulley associated to an engine, height adjustable, related to a second tension pulley that is attached to a pneumatic arm, that acts over the entirety of the pulley and cutting wires; protection bands are installed over each pulley, over which the steel wires with diamond pearls are tighten.
  • Both pulleys are related to each other with the cutting wires (steel wire) with diamond pearls type diamond ends, arranged in a confined cut ring shape.
  • the cutting wires are characterized for having a much smaller length than that of the prior art, from 10 linear meters or more (the prior art is of 28 linear meters) which reduces fatigue and tension in the wire. This way, as there is reduced friction and reduced irregular tension a cut that uses the useful life of the diamond pearls until they are worn out, is obtained, without first having a collapse of the cutting wires, and having to replace them, equating this way the useful life of the diamond pearls with that of the cutting wire or steel cable.
  • protection bands of the polyurethane cover type are installed, over which the pearl steel wires are tightened. Said protection bands are individually replaceable in an easy and fast way since they are installed by force-fitting and in the case of worn out of the cover, it is only necessary to replace the damaged one for a new one.
  • the pulleys are of a small diameter, when they rotate, they allow that while de lower diamond wire makes the material cut, the upper one enters into the cavity made by the lower one without causing any alteration in the original cut.
  • the length of the cutting wires is significantly limited, which can have lengths from 10 linear meters, also limiting both the longitudinal and the horizontal vibration of the wire, extending its useful life while reducing the fatigue of the constituent material of the wire and of the pulley equipment, as well as of all the bearings of the engine equipment.
  • the present invention enables the variation of the cutting thicknesses of the material starting from 10mm; from the change of pulleys the cut can be adapted to the thickness required by the user.
  • the replacement of the pulley allows the variation of the thickness of the diamond wire from 4 mm to 8 mm without significant inconveniences.
  • the pneumatic arm can be hydraulic. It acts over the entirely of the pulley and cutting wires, and can act indistinctly over each cutting wire, using a selector for each independent tension arm. If necessary, in light of an inaccuracy in the provision of the lengths of the wires, or tensional requirements therefore during the cut, this system allows the absorption of their longitudinal differences, using the axis of one of the pulleys of the system as floating instead of fixed, over which a lever arm works that acts as tensor exerting an adjustable force derived from a pneumatic or hydraulic system which modifies the longitudinal location of the pulley axis.
  • the pulleys can vary in their amount depending on the amount of cutting wire necessary. This way, the purpose of the present invention, unlike the prior art, eliminates a great amount of pulleys, which reduces the cost of maintenance. Reduces the length of the diamond cables, which allows that in its useful life the cutting diamond is consumed. Eases the change of protective plastics that are installed by force-fitting (due to the fact that they are small-sized pulleys and are thus feasible to place). Eases the change of pulleys to vary the separation between diamond wires and this way vary thicknesses of cutting plates.
  • the characteristics of the present invention transform the multiwires into machines of very low cost of maintenance, consumption of resources (electric, water and supplies) and simplicity of the working force reducing risks of user personnel.
