Description

Technical Field

[0001] The utility model relates to the technical field of resin cutting blades, in particular to an explosion-proof resin cutting blade with good wear resistance. Background Art

[0002] Resin cutting blades use resin as a binder and glass fiber mesh as a skeleton. They combine multiple materials and have particularly remarkable cutting performance for difficult-to-cut materials such as alloy steel and stainless steel.

[0003] In the use of most existing resin cutting blades, in order to improve the wear resistance of the resin cutting blades, a resin cutting blade with good wear resistance is developed, which can effectively improve the wear resistance of the resin cutting blades and thus increase the service life of the resin cutting blades. However, most of the existing resin cutting blades with good wear resistance will adsorb too much dust on their surfaces due to static electricity. The dust will increase wear and cause the wear resistance of the resin cutting blades to decrease. In view of this, an explosion-proof resin cutting blade with good wear resistance is proposed. Utility Model Content

[0007] In order to achieve the above-mentioned purpose of improving the wear resistance and explosion-proof performance of the resin cutting blade, the utility model provides the following technical solutions: an explosion-proof resin cutting blade with good wear resistance, comprising a resin cutting blade body, the inner surface of the resin cutting blade body is provided with heat dissipation holes, and the outer surface of the resin cutting blade body is provided with grooves.

[0008] Preferably, the resin cutting blade body is composed of a resin base layer and two glass fiber meshes, the resin base layer is the first layer of the resin cutting blade body, and the two glass fiber meshes are connected on both sides of the resin base layer. By setting the glass fiber mesh, the rotation speed of the grinding wheel can be increased, making the cutting more efficient, reducing the fatigue of the grinding wheel, and extending the service life of the grinding wheel. Once the grinding wheel is broken during cutting, the fragments of the broken grinding wheel can be retained, making the cutting operation safer and the side stiffness of the ultra-thin grinding wheel can be increased, making the cutting sharper and more wear-resistant.

[0009] Preferably, the opposite surfaces of the two glass fiber mesh sheets are connected with two high temperature resistant layers, which can isolate the transfer of temperature and make it difficult for the surface of the resin cutting piece to have the problem of rigidity reduction due to high temperature.

[0010] Preferably, the opposite sides of the two high-temperature resistant layers are connected to two anti-static layers, which are composed of conductive fibers. Conductive fibers refer to chemical fibers or metal fibers, carbon fibers spun by mixing conductive media into polymers, thereby preventing the resin cutting blade body from absorbing dust pollutants due to static electricity.

[0011] Preferably, the two opposite sides of the two antistatic layers are connected to two conductive fiber layers, which are chemical fibers or metal fibers or carbon fibers spun by mixing conductive media into polymers, and have excellent performance in eliminating and preventing static electricity, which is much higher than that of antistatic fibers.

[0012] Preferably, the opposite sides of the two conductive fiber layers are connected to two wear-resistant layers, which are high-hardness tungsten-based coated powders made by agglomeration sintering process. The surface of the cast tungsten carbide is coated with a metal cobalt layer for protection and bonding, and has excellent resistance to abrasive wear and high-temperature oxidation.

The conductive fiber refers to chemical fiber or metal fiber, carbon fiber, etc. spun by mixing a conductive medium into a polymer, thereby preventing the resin cutting blade body from absorbing dust and other pollutants due to static electricity, reducing its surface wear and making it more wear-resistant.
