Description

TECHNICAL FIELD

[0001] The utility model belongs to the wire saw technical field especially relates to a wire saw made of core rope. BACKGROUND

[0002] Wire saw, also called diamond wire saw, diamond wire and rope saw, is composed of core wire, consolidation and blade material. The core wire is usually single wire of high strength material, and can also be rope twisted by multiple single wires, which is also called core rope. Through production processes such as electroplating, resin and brazing, the blade material particles are consolidated on the outer periphery of the core wire or core rope by the consolidation, forming a linear cutting material, which is mainly used for cutting high-hardness materials such as crystalline silicon, sapphire, magnetic materials, stone, gem, glass and the like.

[0003] The core wire or core rope of conventional wire saw is made of single material, and the consolidation and blade material particles are continuously distributed on the surface of the core wire or core rope, and the consolidation continuously covers the outer peripheral surface of the core wire or core rope. During the cutting operation of the wire saw, there is little space for accommodating cooling liquid and waste, which affects the cutting efficiency and cutting quality. UTILITY MODEL CONTENT

[0004] In order to solve the technical problem of insufficient space for accommodating cooling liquid and waste on the conventional wire saw in the background art, the utility model aims to provide a wire saw made of core rope, which can solve the above problems.

[0005] The technical scheme for realizing the utility model is as follows: a wire saw made of core rope, characterized in that the wire saw comprises the core rope, blade material and consolidation, and the consolidation consolidates the blade material on the outer periphery of the core rope to form the wire saw. The core rope is twisted by multiple strands, and the multiple strands include inner strands and outer peripheral strands, the outer peripheral strands include conductive strands and insulating strands, the consolidation consolidates the blade material on the conductive strands, and the multiple conductive strands (2) and the insulating strands are arranged in parallel along the axial direction of the core rope to form a spiral groove area.

[0006] The spiral groove area formed by the outer periphery of the wire saw can better accommodate waste and cooling liquid, which is conducive to chip removal and cooling during cutting and helps to improve the efficiency and effectiveness of cutting. The blade material is fixed on part of the strands of the core rope by the binder, that is, part of the strands have blade material, while the rest of the strands do not, so that the parallel arrangement of multiple strands forms a spiral groove area. During cutting, cooling liquid or waste can flow out of the spiral groove area, and the spiral groove area can better accommodate waste and cooling liquid, which is conducive to chip removal and cooling during cutting and helps to improve the efficiency and effectiveness of cutting. In addition, the blade material is a particle or a fine powder of high-hardness material, usually diamond, and can also be cubic boron nitride, etc. The binder is usually a metal that wraps the core rope, such as nickel. The binder combines the blade material with the core rope, and the blade material is distributed on the outer peripheral surface of the core rope. The binding method is usually electroplating or adhesion, and can also be brazing, etc. The multiple strands of the core rope include inner strands and outer peripheral strands, the outer peripheral strands include conductive strands and insulating strands, the blade material is fixed on the conductive strands, and the conductive strands and the insulating strands are arranged in parallel along the axial direction of the core rope to form a spiral groove area. The whole or surface of the conductive strands is made of a conductive material, usually a high-strength metal or alloy such as high-carbon steel, tungsten, molybdenum, etc. The whole or surface of the insulating strands is made of an insulating material such as resin, paint, plastic, aramid, etc. The blade material can be fixed on the conductive strands by electroplating.

[0007] Further, the binder is metal nickel, and the blade material is electroplated on the conductive strands by the metal nickel. Through a binding process such as electroplating, the binder such as metal nickel binds the blade material on the outer peripheral surface of the core rope, thereby making the wire saw. The outer peripheral area of the conductive strands constituting the core rope can be normally electroplated and bound to form a bound blade material area. However, since the insulating strands cannot conduct electricity, the outer periphery of the insulating strands cannot form effective binding during electroplating, so the outer peripheral area of the insulating strands has no bound blade material, i.e. a bound blank area, and the bound blank area forms a spiral groove area along the axial direction of the core rope between the two bound blade material areas. In this way, the bound blade material on the outer periphery of the core rope is distributed in a spiral along the axial direction of the core rope, and there is a spiral groove area without bound blade material between the bound blade materials.

[0008] Further, the ratio of the number of insulating strands to the number of conductive strands on the outer peripheral surface of the core rope is 1:5 or 1:4 or 1:3 or 1:2 or 1:1 or 2:1 or 3:1 or 4:1 or 5:1, or other suitable ratios. The core rope twisted according to the appropriate ratio has good quality, strong toughness, good cutting effect, and moderate proportion of the spiral groove area.

[0009] Further, when the diameters of the conductive strands and the insulating strands are different, the diameter of the insulating strands is smaller than the diameter of the conductive strands, which can increase the depth of the spiral groove and improve the cutting effect.

[0010] Further, the insulating strand is coated with an insulating coating outside the conductive strand, that is, it is not necessary to develop a whole insulating material to make the strand, but only to coat the insulating coating outside the conductive strand, thereby reducing the cost of developing and producing the insulating strand by the enterprise.

[0011] Further, the diameter of the strand is 0.02mm-2mm, and the strand constituting the core rope can be a single wire or a strand formed by multiple single wires. If the strand is a single wire, the diameter is also 0.02mm-2mm.

[0012] Further, the strand can be composed of multiple single wires, or the whole strand is a single wire, thereby obtaining different core rope strength and flexibility to match different cutting requirements.

[0013] Further, the inner strand of the core rope forms a core rope center part, and the center part can be a strand composed of multiple single wires, thereby obtaining better core rope flexibility and fatigue resistance. The center part can be a strand or a single wire, thereby obtaining higher core rope strength.

[0014] Further, the wire saw can be a long linear wire saw with two end points, or a ring type wire saw with no end points.

[0015] By adopting the above technical scheme, the utility model has the following beneficial effects:

[0016] (1) The spiral groove area part of the wire saw has no solidified material and blade material, can better accommodate the swarf and cooling liquid, is beneficial to the swarf removal and cooling liquid flow during cutting, and helps to improve the cutting efficiency and effect;

[0017] (2) The arrangement of the spiral groove area can reduce the amount of blade material and solidified material, and reduce the manufacturing cost;

[0018] (3) The spiral groove area has no hard solidified material, helps to improve the flexibility and fatigue resistance of the whole wire saw, and prolongs the service life of the diamond rope;

[0019] (4) The insulating strand can be formed by coating the insulating coating outside the conductive strand, thereby reducing the cost of developing and producing the insulating strand by the enterprise;

[0020] (5) The number of the insulating strand and the conductive strand on the outer circumferential surface of the core rope is set in a certain proportional relationship, a suitable balance is obtained in terms of cutting ability and swarf removal ability, and different cutting applications are met;

[0021] (6) The strands that make up the core rope can be a single filament or multiple filaments, selected as needed for the use scenario to achieve the appropriate saw strength and flexibility. BRIEF DESCRIPTION OF DRAWINGS

[0031] Example 1:

[0032] As Figures 1-3As shown, the present embodiment provides a wire saw made of a core rope, the wire saw comprising a core rope 6, a blade material 5 and a consolidant 4, the consolidant 4 consolidating the blade material 5 on the outer periphery of the core rope 6 to form the wire saw. The core rope 6 is made of a plurality of strands 9 twisted spirally, the plurality of strands 9 comprising inner strands and outer periphery strands. The outer periphery strands comprise conductive strands 2 and insulating strands 1, the consolidant 4 consolidating the blade material 5 on the conductive strands 2 of the core rope 6. The plurality of conductive strands 2 with the blade material 5 and the insulating strands 1 without the blade material are arranged axially in parallel along the core rope 6 to form a spiral groove area 7. During cutting, cooling liquid or waste chips and the like can flow out from the spiral groove area 7, which can better accommodate the waste chips and the cooling liquid, facilitate chip removal and cooling during cutting, and help improve the efficiency and effect of cutting.

[0033] Preferably, the whole or surface of the conductive strands 2 is made of electrically conductive material, typically high-strength metal or alloy such as high-carbon steel, tungsten, molybdenum, etc. The whole or surface of the insulating strands 1 is made of insulating material such as resin, paint, plastic, aramid, etc. The blade material 5 can be fixed on the conductive strands 2 by electroplating.

[0034] Preferably, the consolidant 4 is metal nickel, and the blade material 5 is electroplated on the conductive strands 2 by the metal nickel. The blade material 5 is consolidated on the outer periphery surface of the twisted core rope 6 by the consolidant 4 such as metal nickel through a consolidation process such as electroplating, thereby making the wire saw. The outer periphery area of the conductive strands 2 constituting the core rope 6 can be normally electroplated and consolidated to form a consolidated blade material area 8. However, the outer periphery area of the insulating strands 1 cannot be effectively consolidated due to the non-conductivity of the insulating strands 1 during electroplating, so that the outer periphery area of the insulating strands 1 is free of the consolidated blade material 5, i.e. a consolidated blank area, which forms the spiral groove area 7 axially along the core rope 6 between the consolidated blade materials 5 on both sides. In this way, the consolidated blade material 5 on the outer periphery of the core rope 6 is distributed spirally axially along the core rope 6, and the spiral groove area 7 without the consolidated blade material 5 is formed between the consolidated blade materials 5.

[0035] Preferably, the ratio of the number of the insulating strands 1 to the conductive strands 2 on the outer periphery surface of the core rope 6 is 1:5, 1:4, 1:3, 1:2, 1:1, 2:1, 3:1, 4:1, 5:1 or other suitable ratios, and the core rope 6 twisted spirally according to the suitable ratio has good quality, high toughness and good cutting effect, and the spiral groove area 7 has a moderate proportion.

[0036] Preferably, when the diameters of the conductive strand 2 and the insulating strand 1 are different, the diameter of the insulating strand 1 is smaller than the diameter of the conductive strand 2, so as to ensure the area of ​​the solidification zone of the cutting material 5 and improve the cutting effect.

[0037] Preferably, the insulated strand 1 is an insulating coating layer 3 covering the outside of the conductive strand 2. That is to say, it is not necessary to develop a strand 9 made of integral insulating material separately. It is only necessary to cover the outer periphery of the conductive strand 2 with the insulating coating layer 3, which reduces the cost for enterprises to develop and produce the insulated strand 1 separately.

[0038] Preferably, the diameter of the strand 9 is 0.02mm to 2mm. The strand 9 constituting the core rope 6 can be a single filament or a strand 9 formed by multiple single filaments. If the strand 9 is a single filament, its diameter is also 0.02mm to 2mm.

[0039] Preferably, the strand 9 is composed of multiple monofilaments, which are spirally twisted to form the strand 9, and then the strand 9 is spirally twisted to form the core rope 6, resulting in a stronger structure.

[0040] Preferably, the strand 9 is a monofilament, which has a simple structure and is easy to manufacture into the core rope 6.

[0041] Preferably, the internal strands of the core rope form the core rope center, which can be composed of strands of multiple monofilaments, thereby obtaining better core rope flexibility and fatigue resistance; the center can also be a monofilament, thereby obtaining higher core rope strength.

[0042] like Figure 4 As shown, the core rope 6 can have various cross-sections, such as a seven-core rope 6, which consists of four conductive monofilaments 11 and three insulating monofilaments 10 twisted together. The central monofilament is a conductive monofilament 11, and three of the outermost monofilaments are conductive monofilaments 11, while the other three are insulating monofilaments 10. The conductive monofilaments 11 and insulating monofilaments 10 are arranged alternately. The insulating monofilaments 10 are formed by wrapping the conductive wire with an insulating coating layer 3. During electroplating, the nickel metal solidifies the cutting edge 5 around the conductive monofilaments 11, while the insulating monofilaments 10 cannot be electroplated to form a nickel layer, and therefore there is no cutting edge 5 around them; this is the solidification blank area. The solidification blank area forms a spiral groove area 7 along the axial direction of the core rope 6 in the solidified cutting edge 5 on both sides.

[0043] Preferably, the conductive monofilament 11 can be a high-carbon steel wire or other metal wires with excellent tensile strength, such as tungsten wire, molybdenum wire, metal alloy wire, etc.; the insulating monofilament 10 can also be a monofilament or bundle of non-metallic insulating materials such as resin-impregnated carbon fiber or aramid fiber.

[0044] Preferably, the ratio of the number of conductive monofilaments 11 to insulating monofilaments 10 on the outer circumference can be 1:5, 1:4, 1:3, 1:2, 1:1, 2:1, 3:1, 4:1, 5:1, or other suitable ratios.

[0045] Preferably, the diameter of the conductive monofilament 11 is 0.02 mm to 2.0 mm.

[0046] Preferably, the conductive filament 11 and the insulating filament 10 have the same diameter, or the diameter of the conductive filament 11 is slightly larger than the diameter of the insulating filament 10.

[0047] Example 2:

[0048] like Figure 5 As shown, the cross-section of the core rope 6 can also be a thirteen-core rope 6 cross-section, that is, the core rope 6 is made of thirteen monofilaments of different diameters twisted together. The central monofilament is a conductive monofilament 11, and the twelve monofilaments distributed around the outer circumference are composed of conductive monofilaments 11 and insulating monofilaments 10.

[0049] Preferably, the twelve twisted wires distributed around the outer circumference of the core rope 6 consist of three insulating monofilaments 10 and nine conductive monofilaments 11, with the three insulating monofilaments arranged continuously.

[0050] Preferably, the number of insulating monofilaments 10 and conductive monofilaments 11 around the core rope 6 can be increased or decreased, for example, four insulating monofilaments 10 + nine conductive monofilaments 11 or seven insulating monofilaments 10 + five conductive monofilaments 11.

[0051] Preferably, the distribution of insulating monofilaments 10 on the outer circumferential surface of the core rope 6 can be continuous or alternating with conductive monofilaments 11.

[0052] like Figure 6 As shown, the central conductive monofilament 11 can be replaced with strand 9, for example, with a 1*7 monofilament structure, so that the core rope 6 becomes a 1*19 monofilament structure.

[0053] like Figure 7 As shown, the diameter of the insulating monofilament 10 on the outer periphery of the core rope 6 is different from that of the conductive monofilament 11.

[0054] Working principle: The cutting material 5 is fixed on a portion of the strands 9 by the fixing material 4. Some strands 9 have the cutting material 5, while the rest of the strands 9 do not. In this way, multiple strands 9 are arranged in parallel to form multiple spiral groove areas 7. During the cutting process, coolant or waste chips can flow out from the spiral groove areas 7, which can also better accommodate waste chips and coolant, which is beneficial for chip removal and cooling during cutting, and helps to improve the efficiency and effect of cutting.

[0055] The above-described specific embodiments further specifically describe the purposes, technical solutions and beneficial effects of the present application, and it should be understood that the above-described specific embodiments are merely examples of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
