Description

Technical Field

[0001] This utility model relates to the field of diamond saw blade technology, specifically to a multi-groove diamond saw blade. Background Technology

[0002] Currently, diamond saw blades are widely used in stone processing, concrete cutting, and other fields, and their performance directly affects cutting efficiency, quality, and service life. Traditional diamond saw blades typically have diamond cutting heads arranged circumferentially around the saw blade body, and the structure between adjacent cutting heads is relatively simple.

[0003] In practical use, these types of saw blades present numerous problems. On one hand, the traditional saw blade head structure is not conducive to chip removal and heat dissipation, leading to chip accumulation during cutting, increased cutting resistance, reduced efficiency, and accelerated head wear due to the inability to dissipate heat promptly. On the other hand, the saw blade substrate experiences uneven stress distribution during cutting, easily resulting in stress concentration, reducing the strength of the saw blade substrate, and affecting the overall stability and service life of the saw blade. To address these issues, optimizing the structure of diamond saw blades is essential. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a multi-groove diamond saw blade.

[0005] To achieve the above objectives, this application discloses a multi-groove diamond saw blade, comprising: a saw blade base, and a plurality of diamond cutting heads arranged circumferentially along the saw blade base, wherein an opening groove is formed between adjacent diamond cutting heads, and a V-shaped groove is formed in the middle of each diamond cutting head; the opening groove extends toward the center of the saw blade base, and the lengths of adjacent opening grooves are different.

[0006] The opening slot includes a long slot and a short slot, and the long slot and the short slot are arranged alternately.

[0007] The surface of the diamond cutting head is provided with a groove, and the inner end of the groove extends to the saw blade base.

[0008] The outer side of the saw blade substrate is coated with a thermally conductive coating that extends into the groove.

[0009] The saw blade base is provided with heat dissipation holes, and air guides are installed inside the heat dissipation holes, with the air guides being inclined.

[0010] The saw blade of this application features slots between adjacent diamond cutting heads that extend towards the center of the saw blade substrate. These slots effectively accommodate chips generated during cutting, facilitating smoother chip removal and reducing cutting resistance caused by chip accumulation, thereby improving cutting efficiency. The varying lengths of the adjacent slots effectively disperse stress generated during cutting, preventing stress concentration in specific areas and reducing the impact on the strength of the saw blade substrate. This enhances the structural stability of the saw blade substrate and extends the service life of the saw blade. Attached Figure Description

[0015] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0016] Example 1: As Figure 1-3 As shown, a multi-groove diamond saw blade includes: a saw blade base 101, and a plurality of diamond cutting heads 102 arranged circumferentially along the saw blade base 101. An opening groove 103 is formed between adjacent diamond cutting heads 102, and a V-shaped groove 104 is formed in the middle of each diamond cutting head 102. The multi-groove diamond saw blade consists of the saw blade base 101 and the plurality of diamond cutting heads 102. The saw blade base is the basic structural part of the saw blade, providing support and mounting for the diamond cutting heads. The diamond cutting heads are the key components for the saw blade to achieve its cutting function, utilizing the high hardness of diamond to cut the material being cut; the opening groove 103 between adjacent diamond cutting heads facilitates chip removal during cutting.

[0017] The slots 103 extend toward the center of the saw blade substrate 101, and adjacent slots 103 have different lengths. When the saw blade is cutting, the saw blade substrate needs to withstand forces from all directions. If adjacent slots are the same length, under certain working conditions, stress may concentrate in certain areas, such as the ends of the slots. When adjacent slots are of different lengths, the stress is relatively dispersed. The alternating arrangement of long and short slots prevents stress from concentrating in a few specific locations, but distributes it over a wider area. This relatively reduces the stress at each point, lowering the risk of cracks or even breakage in the saw blade substrate due to stress concentration, thus ensuring the strength of the saw blade substrate.

[0018] The opening slot 103 includes a long slot 103a and a short slot 103b, which are arranged alternately. The different lengths of adjacent opening slots can enhance the structural integrity of the saw blade substrate to a certain extent. The short slots can provide some support and connection to the area between the long slots, allowing the saw blade substrate to better maintain its shape and structural stability when subjected to external forces, preventing the overall strength of the saw blade substrate from being affected by excessively weak local structures.

[0019] Example 2: Figure 3 As shown, the surface of the diamond cutter head 102 is provided with a groove 105, and the inner end of the groove 105 extends to the saw blade base 101.

[0020] The outer side of the saw blade substrate 101 is coated with a thermally conductive coating 106, which covers the groove 105. The outer side of the saw blade substrate 101 is coated with a thermally conductive coating 106, and the thermally conductive coating 106 covers the groove 105.

[0021] In this embodiment, the main function of the thermally conductive coating is to improve the heat dissipation performance of the saw blade substrate. In one specific embodiment, the thermally conductive coating can be a copper coating or a graphene coating. During the saw blade cutting process, both the blade head and the substrate generate heat. The thermally conductive coating can quickly transfer the heat away, preventing heat from accumulating on the saw blade. The thermally conductive coating covers the groove 105, further enhancing the overall heat dissipation effect of the saw blade, allowing the groove 105 to play a greater role in heat dissipation.

[0022] Example 3: As Figure 1 and 4As shown, the saw blade base 101 has heat dissipation holes 107, and air guide vanes 108 are disposed within the heat dissipation holes 107, with the air guide vanes 108 being inclined. The inclined arrangement of the air guide vanes 108 further enhances the airflow effect. The inclined air guide vanes can utilize the centrifugal force generated when the saw blade rotates to allow air to enter and exit the heat dissipation holes more smoothly. When the saw blade rotates, the inclined air guide vanes generate a guiding force on the air, causing the air to flow along the inclined direction of the air guide vanes, forming a regular airflow. The air velocity in the heat dissipation holes increases, which can more quickly remove the heat from the saw blade base, thereby significantly improving the heat dissipation efficiency.

[0023] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
