[0017] In order to deepen the understanding of the present utility model, the following will further describe the present utility model in detail in conjunction with embodiments. The embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.
[0018] According to Figures 1-3As shown in the figure, this embodiment provides a heat-sensitive temperature type diamond cutting saw blade, which includes a substrate 1 and cutting heads 2. The cutting heads 2 are provided at the outer edge of the substrate 1, and a shaft hole 3 is provided at the center of the substrate 1. The cutting heads 2 are provided with first heat dissipation grooves 4, and a plurality of first heat dissipation grooves 4 are equiangularly arranged on the cutting heads 2. The substrate 1 is provided with first heat dissipation holes 5, and a plurality of first heat dissipation holes 5 are equiangularly arranged on the substrate 1 and the number of first heat dissipation holes 5 is adapted to the number of first heat dissipation grooves 4. One end of the first heat dissipation groove 4 extends towards the substrate 1 and communicates with the first heat dissipation hole 5. On the front surface of the substrate 1 on one side of the first heat dissipation hole 5, there is an installation hole 6, and a heat conducting sheet 7 is arranged in the installation hole 6. The heat conducting sheet 7 is annular and multiple groups are arranged in the installation hole 6. A thermosensitive sheet 8 is arranged at the center of the installation hole 6. Between adjacent first heat dissipation holes 5 on the substrate 1, there is a continuous heat dissipation channel, and the continuous heat dissipation channel is composed of a plurality of second heat dissipation holes 9. The plurality of second heat dissipation holes 9 are arranged in a spiral arc shape on the substrate 1.
[0019] The heat-sensitive temperature process of the heat-sensitive temperature type diamond cutting saw blade of the present utility model is as follows: The heat during the operation of the saw blade is transferred to the heat conducting sheet 7 and then transferred to the thermosensitive sheet 8 by the heat conducting sheet 7. After the thermosensitive sheet 8 senses the heat, it changes color, and the temperature of the saw blade is judged according to the depth of the color change. The first heat dissipation grooves 4, the first heat dissipation holes 5 and the second heat dissipation holes 9 of the present utility model can comprehensively improve the heat dissipation capacity of the saw blade.
[0020] Copper nails 10 are arranged in the first heat dissipation holes 5, and both ends of the copper nails 10 protrude from the inside of the first heat dissipation holes 5. During the high-speed rotation and cutting process of the saw blade, vibrations will be generated, and these vibrations are one of the main sources of noise. The copper nails 10 are arranged in the first heat dissipation holes 5 as inlays. Due to the damping characteristics of the material of the copper nails 10, they can absorb and disperse part of the vibration energy, thereby reducing the amount of vibration transmitted to the substrate 1 and the surrounding environment, and further reducing the generation of noise. Copper is an excellent heat conducting material, and its heat conduction performance is much better than that of the substrate 1. After inlaying copper nails 10 on the saw blade, the copper nails 10 can serve as a "bridge" for heat conduction, quickly transferring the heat generated during the cutting process of the saw blade to the edge or surrounding environment of the saw blade. This form of heat conduction can significantly reduce the working temperature of the saw blade, prevent performance degradation and damage caused by overheating. The embedding of the copper nails 10 also increases the total heat dissipation area of the saw blade. Although the area occupied by the copper nails 10 themselves is relatively small, they can form multiple raised heat dissipation points on the surface of the saw blade. These heat dissipation points not only increase the contact area between the saw blade and the air, but also may generate local air flow disturbances when the saw blade rotates, promoting air convection and heat exchange, thereby improving the heat dissipation efficiency.
[0021] The second heat dissipation groove 11 is provided on the cutter head 2. The second heat dissipation groove 11 is arranged between adjacent first heat dissipation grooves 4, and the length of the second heat dissipation groove 11 is 1 / 4 of the length of the first heat dissipation groove 4. By setting the length of the second heat dissipation groove 11, while ensuring the excellent heat dissipation capacity of the saw blade, the overall structure strength of the saw blade is also ensured, so that the cutter head 2 of the saw blade is not prone to chipping.
[0022] The apertures of the plurality of second heat dissipation holes 9 arranged in a spiral arc shape on the base body 1 increase sequentially from the inside out from the shaft hole 3. The aperture of the second heat dissipation hole 9 with the largest aperture is 1 / 3 of the aperture of the first heat dissipation hole 5, and the aperture of the second heat dissipation hole 9 with the smallest aperture is 1 / 5 of the aperture of the first heat dissipation hole 5. The plurality of second heat dissipation holes 9 with apertures increasing from the inside out in a spiral arc shape can form a spiral blade structure on the base body 1, so that a cyclone air flow can be generated when the saw blade rotates, accelerating the air flow speed, thereby improving the heat dissipation effect; by limiting the aperture of the second heat dissipation hole 9 in the present invention, it can be ensured that the base body 1 has good structural strength, and the saw blade is not prone to generate large vibration noise during use.
[0023] The base body 1 includes a base layer 101 and a ceramic heat dissipation coating 102. The ceramic heat dissipation coating 102 is provided on both sides of the base layer 101, and the thickness of the ceramic heat dissipation coating 102 is 1 / 3 of the thickness of the base layer 101. By setting the base body 1 to be composed of the base layer 101 and the ceramic heat dissipation coating 102, the wear resistance, heat conductivity and heat dissipation performance of the saw blade can be improved through the ceramic heat dissipation coating 102.
[0024] Heat insulation rings 12 are provided on both the front and back sides of the base body 1 outside the shaft hole 3. By providing the heat insulation rings 12, it can prevent heat from being transferred to the shaft hole 3 too quickly, causing overheating and deformation of the base body 1 at the shaft hole 3.
[0025] The heat-sensitive temperature type diamond cutting saw blade of the present invention realizes heat-sensitive temperature through the heat conduction sheet 7 and the thermosensitive sheet 8 arranged in the mounting hole 6. After the temperature is transferred to the thermosensitive sheet 8, the thermosensitive sheet 8 changes color to prompt the temperature rise situation; in the present invention, by providing the first heat dissipation groove 4 on the cutter head 2 to communicate with the first heat dissipation hole 5 provided on the base body 1, and by providing a continuous heat dissipation channel composed of a plurality of second heat dissipation holes 9 arranged in a spiral arc shape on the base body 1 between adjacent first heat dissipation holes 5, the heat dissipation capacity of the saw blade can be effectively improved. The heat dissipation structure is diversified, avoiding the problem of insufficient heat dissipation caused by a single heat dissipation form. The plurality of second heat dissipation holes 9 with apertures increasing from the inside out in a spiral arc shape can form a spiral blade structure on the base body 1, so that a cyclone air flow can be generated when the saw blade rotates, accelerating the air flow speed, thereby improving the heat dissipation effect.
