Description

Technical Field

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

[0002] Ring saw blades, with their high-efficiency cutting performance, are widely used in many important industries such as construction, metal processing, and wood processing. In the construction field, they are key tools for cutting hard materials such as concrete and stone; in the metal processing industry, they can precisely cut various metal sheets; and in the wood processing process, ring saw blades play an indispensable role in cutting both logs and boards.

[0003] However, in actual cutting operations, the intense friction between the ring saw blade and the material being cut generates a large amount of heat. The continuously accumulated heat not only significantly reduces the cutting efficiency of the saw blade, accelerates the wear of the saw blade tip, and greatly shortens the service life of the saw blade, but may also cause the saw blade substrate to deform due to high temperatures, thereby affecting cutting accuracy and even causing safety accidents.

[0004] Currently, some ring saw blades improve heat dissipation by adding ventilation holes or optimizing the cutter head structure, but these methods have limitations. Simply adding ventilation holes may weaken the structural strength of the saw blade substrate and reduce its stability; existing optimized cutter head structures have limited heat dissipation effects and cannot meet the heat dissipation requirements of long-term, high-intensity cutting operations. Therefore, there is an urgent need to develop a technical solution that can effectively improve the heat dissipation performance of ring saw blades while ensuring the structural strength and cutting stability of the saw blade. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a diamond ring saw blade.

[0006] To achieve the above objectives, this application discloses a diamond ring saw blade, comprising: a saw blade base; a plurality of diamond cutting heads, wherein the diamond cutting heads are arranged circumferentially along the saw blade base; a U-shaped groove is formed between adjacent diamond cutting heads, and a V-shaped groove is formed in the middle of each diamond cutting head.

[0007] The bottom of the U-shaped groove is provided with ventilation holes, and the two ends of the ventilation holes pass through two adjacent U-shaped grooves respectively.

[0008] The paths of the ventilation holes on the multiple U-shaped grooves are curved inward into an arc shape and are consistent with the rotation trajectory of the saw blade base.

[0009] The paths of the ventilation holes between two adjacent U-shaped grooves are staggered.

[0010] The inner wall of the U-shaped groove is provided with multiple fins.

[0011] Both ends of the fin are retracted into the U-shaped groove.

[0012] Compared to traditional diamond ring saw blades, the diamond ring saw blade of this application utilizes a combination of U-shaped and V-shaped grooves to create an effective heat dissipation channel, preventing overheating during prolonged high-speed cutting and extending its service life. Furthermore, the U-shaped groove provides greater chip removal space, preventing chip accumulation that could cause jamming or damage to the workpiece surface. Attached Figure Description

[0016] 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.

[0017] Example 1: As Figure 1 As shown, a diamond ring saw blade is commonly used in industries such as construction, metal processing, and wood processing. For example, in construction, it is used to cut materials such as concrete and stone; in metal processing, it can cut various metal sheets; and in wood processing, it can be used to cut logs and planks.

[0018] The diamond ring saw blade in this embodiment includes: a saw blade base 101; a plurality of diamond cutting heads 102, the diamond cutting heads being arranged circumferentially along the saw blade base; a U-shaped 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.

[0019] The saw blade base 101 is the basic structure of the saw blade, usually made of high-strength metal materials (such as steel alloys). The saw blade base has a ring structure, which is used to support the cutter head and withstand the centrifugal force during high-speed rotation.

[0020] The diamond cutting tip is the part that actually performs the cutting. It is made by sintering diamond particles with a metal binder. The cutting tip is evenly distributed around the circumference of the saw blade base to ensure a smooth and balanced cutting process.

[0021] The main function of the U-shaped groove 103 is to increase the air circulation space, which helps to dissipate heat during the cutting process; at the same time, it can provide chip space to facilitate the discharge of cutting chips; it can also reduce the weight of the saw blade and reduce energy consumption during high-speed rotation.

[0022] The V-groove 104 creates an additional, directional flow path, allowing coolant or air to flow not only on the cutter head surface but also along the recessed portion of the V-groove, further enhancing the cooling effect. During cutting, it guides the coolant or air to more effectively cover the entire cutter head area, especially near the cutting face, where heat is concentrated and critical areas require rapid cooling. The V-groove 104 ensures that the cooling medium is distributed more evenly across the cutter head, rather than being concentrated in certain localized areas.

[0023] The saw blade design in this embodiment, compared to traditional diamond ring saw blades, utilizes a U-shaped groove and a V-shaped groove to form an effective heat dissipation channel, preventing the saw blade from overheating during prolonged high-speed cutting and extending its service life. Furthermore, the U-shaped groove provides a larger chip removal space, preventing chip accumulation that could cause jamming or damage to the workpiece surface.

[0024] Example 2: As Figure 2-3 As shown, this embodiment further improves the heat dissipation structure based on embodiment 1. Specifically, a ventilation hole 105 is provided at the bottom of the U-shaped groove 103, and the two ends of the ventilation hole 105 respectively penetrate two adjacent U-shaped grooves 103. When the saw blade rotates, air will flow in the ventilation hole, and the heat of the saw blade surface and cutting area will be carried away by forced convection, thus achieving a cooling effect.

[0025] The paths of the ventilation holes 105 on the plurality of U-shaped grooves 103 are curved inward into an arc shape and are consistent with the rotation trajectory of the saw blade base 101. The arc design can better adapt to the rotational movement of the saw blade. When the saw blade rotates, due to the inertia of the air, it is easier to maintain a continuous motion state when flowing along the arc-shaped ventilation holes, reducing energy loss and thus more effectively carrying heat away from the saw blade.

[0026] The ventilation holes 105 between two adjacent U-shaped grooves 103 are staggered. When the saw blade is subjected to external force during cutting, the staggered ventilation holes make the stress distribution on the saw blade substrate more uniform, avoiding excessive local stress.

[0027] Example 3: As Figure 2 As shown, multiple fins 106 are provided on the inner wall of the U-shaped groove 103. The presence of the fins increases the surface area of ​​the inner wall of the U-shaped groove, thereby increasing the contact area with air, promoting heat exchange, and accelerating heat dissipation.

[0028] Both ends of the fin 106 are retracted into the U-shaped groove 103. The retraction of both ends of the fin 106 into the U-shaped groove 103 can protect the fin and prevent it from being subjected to unnecessary collisions and wear during the operation of the saw blade, while ensuring the safety and reliability of the overall structure of the saw blade.

[0029] 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.
