Description

Technical Field

[0001] The utility model relates to the technical field of diamond wire saws, in particular to a diamond wire saw. Background Art

[0002] A diamond wire saw is a cutting tool that uses diamond particles as the cutting edge and is fixed to a metal wire (usually a high-strength steel wire) through an electroplating process or resin bonding.

[0003] The existing diamond wire saw uses steel wire as the base layer. However, during the high-speed rotation and high-load cutting process of the steel wire, the steel wire is repeatedly subjected to tensile, bending and torsional stresses, which can easily generate tiny cracks that gradually expand and eventually lead to fatigue fracture. Utility Model Content

[0004] In view of this, the utility model provides a diamond wire saw, which can enable the wire saw to withstand a greater cutting force, avoid the wire saw from breaking, and reduce the shedding of diamond particles.

[0005] In order to solve the above technical problems, the utility model provides a diamond wire saw, including a base layer, the base layer includes alloy steel and tungsten wire, the tungsten wire and the alloy steel are twisted, an electroplating layer 1 is provided on the outer surface of the base layer, a resin layer is provided on the outer surface of the electroplating layer 1, diamond particles are evenly laid on the resin layer, an electroplating layer 2 is provided on the outer surface of the diamond particles, and the protruding ends of the diamond particles are located on the outer surface of the electroplating layer 2; that is, by uniformly twisting the alloy steel and the tungsten wire, the strength and wear resistance between the alloy steel and the tungsten wire are enhanced, so that the wire saw can withstand a greater cutting force and avoid fatigue fracture, and then the electroplating layer 2 and the resin layer can well wrap the diamond particles to prevent them from falling during cutting.

[0006] The base layer includes carbon fiber powder, and the outer surfaces of the tungsten wire and the alloy steel are covered with the carbon fiber powder; that is, the wear resistance of the base layer is enhanced.

[0007] The diameter of the base layer is 0.1 mm to 0.15 mm, that is, the flexibility and cutting performance of the wire saw are maintained.

[0008] The thickness of the second electroplating layer is greater than that of the first electroplating layer, which can ensure that the diamond particles are better fixed and protected, thereby improving the overall performance and life of the diamond wire saw.

[0009] The particle size of the diamond particle layer is 10 microns to 18 microns; that is, the particle size of the diamond particle layer can be better laid on the base layer.

[0010] The materials of the first and second electroplating layers are nickel or chromium, which improves the cutting effect, durability and stability of the diamond wire saw.

[0011] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0012] 1. Twist the tungsten wire and alloy steel evenly, then evenly coat the tungsten wire and alloy steel with carbon fiber powder, and then heat press or sinter them. This can enhance the bonding force between the carbon fiber powder and the matrix layer, making them more closely combined, indirectly improving the strength and wear resistance, allowing the wire saw to withstand greater cutting force, and avoiding wire saw breakage.

[0013] 2. The diamond particles can be effectively fixed by the resin layer, the first electroplating layer and the second electroplating layer, thereby reducing the shedding of the diamond particles. BRIEF DESCRIPTION OF THE DRAWINGS

The alloy steel provides good rigidity and strength to ensure the stability of the wire saw during the cutting process. The twisted arrangement of the tungsten wire 102 and the alloy steel further enhances the strength and wear resistance of the base layer 100, so that the wire saw can withstand greater cutting force and avoid the wire saw from breaking. The electroplating layer 200 on the outer surface of the base layer 100 protects the base layer 100 from corrosion and wear. The outer surface of the electroplating layer 200 is provided with a resin layer 201, and the resin layer 201 is evenly laid with diamond particles 203. The outer surface of the electroplating layer 200 is coated with the resin layer 201, and the resin layer 201 has good adhesion and can well adhere the diamond particles 203, thereby improving the wear resistance and impact resistance of the wire saw.

The fiber powder provides an additional reinforcement effect for the base layer 100 with its light weight and high strength characteristics;

[0023] The diameter of the base layer 100 is 0.1 mm to 0.15 mm, which can ensure that the diamond particles 203 are evenly distributed on the wire saw, and can take into account both manufacturing costs and cutting performance while ensuring strength and rigidity;
