[0003] Its ingenious design consists of two core components: a stable base body and a sharp saw blade. The base body, as the solid backing of the saw blade, not only bears the overall structure of the saw blade but also shoulders the important mission of firmly bonding the diamond cutting heads. The saw blade, on the other hand, is the cutting edge for performing the cutting task, and its excellent performance stems from the built-in diamond particles.
[0004] During operation, the triangular grinding wheel itself is prone to generating high temperatures and lacks an effective heat dissipation mechanism. This continuous high temperature may not only cause deformation of the saw blade, affecting its cutting accuracy and stability, but also accelerate the material aging due to long-term heating, significantly reducing its service life. Therefore, a high-strength triangular grinding wheel is proposed to solve the above problems. Summary of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1 and Figure 2, An embodiment provided by the present utility model: A high-strength triangular grinding wheel, which includes a base body 1. As the main structure of the entire device, it plays a role in supporting and connecting other components. The middle part of the base body 1 protrudes upward to facilitate installation through the installation hole 2. A through installation hole 2 is provided in the middle of the top end of the base body 1 for installing the entire device on corresponding equipment or tools. A triangular grinding disc 3 is fixedly connected to the bottom end of the base body 1. There are multiple groups of triangular grinding discs 3, and diamond particles are provided inside, which are mainly responsible for the grinding work. A grinding groove 5 is provided at the bottom end of the triangular grinding disc 3. The opening directions of the grinding grooves 5 provided on two adjacent groups of triangular grinding discs 3 are opposite. The reaction forces generated during the grinding operation can cancel each other out or partially cancel each other out, thereby reducing the vibration and instability of the overall structure and improving the stability and precision of grinding. A heat dissipation component is provided on the outer wall of the base body 1. The heat dissipation component includes a guide plate 41. The top end of the guide plate 41 is fixedly connected to the bottom end of the base body 1. The guide plate 41 is inclined. On the one hand, it is fixedly connected between the base body 1 and the triangular grinding disc 3, playing a role in strengthening the connection. On the other hand, it helps to guide the air flow and assist in heat dissipation. One end of the guide plate 41 close to the inner side of the base body 1 is fixedly connected to the outer wall of the triangular grinding disc 3. A first heat dissipation hole 42 is provided through the outer side of the top end of the base body 1. When the base body 1 rotates, the inclined first heat dissipation hole 42 can produce an effect similar to that of a fan blade. Due to its inclined angle, a certain air flow guiding effect will be generated during the rotation process, making it easier for the external cold air to be inhaled and the internal hot air to be discharged more smoothly, increasing the speed and flow rate of air circulation, thereby improving the efficiency of heat exchange, effectively reducing the temperature inside the base body 1, ensuring the stability and reliability of the equipment during the working process, reducing the risk of failures and damages that may be caused by overheating, and extending the service life of the equipment.
[0032] Refer to Figure 1 and Figure 3, a second heat dissipation hole 43 for heat dissipation is formed through the base body 1 near the middle of two adjacent sets of triangular grinding discs 3. The bottom end of the second heat dissipation hole 43 is close to the left side of the guide plate 41, which helps to guide the air flow. During the process of the guide plate 41 guiding the air flow to assist in heat dissipation, the second heat dissipation hole 43 can better cooperate with the guide plate 41, making the air flow more smooth, enhancing the heat dissipation effect. When the equipment is working, the generated heat can be dissipated outward through these second heat dissipation holes 43, reducing the temperature of the base body 1 and the triangular grinding discs 3, ensuring the normal operation of the equipment, and extending the service life. In addition, the second heat dissipation hole 43 also helps to discharge the debris ground by the triangular grinding discs 3, preventing the debris from accumulating inside the equipment and affecting the grinding effect and the normal operation of the equipment. A first reinforcing ring 44 is fixedly connected to the top end of the base body 1, providing the first reinforcement line of defense, which can reduce the possibility of deformation or damage of the base body 1. A second reinforcing ring 45 is fixedly connected to the outside of the top end of the base body 1 near the first reinforcing ring 44, further increasing the strength and stiffness of the base body 1. Cooperating with the first reinforcing ring 44, a double reinforcement barrier is formed, which can better disperse and bear external loads, improving the strength and stability of the top end of the base body 1 in a complex working environment. A wind guide plate 46 is fixedly connected between the first reinforcing ring 44 and the second reinforcing ring 45, and the wind guide plate 46 is arranged directly above the second heat dissipation hole 43.
[0033] Refer to Figure 1 , Figure 3 and Figure 4 , multiple groups of wind guide plates 46 are provided. The multiple groups of wind guide plates 46 are inclined. When the equipment is running, the surrounding air will flow due to the operation of the equipment. The presence of the wind guide plates 46 can guide and regularize the originally disordered air flow, making it flow more specifically towards the second heat dissipation hole 43. By guiding the air flow into the second heat dissipation hole 43, the amount of air entering the heat dissipation area can be increased, thereby improving the efficiency of heat exchange. At the same time, the wind guide plate 46 connects the first reinforcing ring 44 and the second reinforcing ring 45, which can enhance the stability and integrity of the entire structure. Multiple groups of the first heat dissipation holes 42 and the second heat dissipation holes 43 are formed. The multiple groups of the first heat dissipation holes 42 and the second heat dissipation holes 43 are circumferentially arrayed around the center line of the base body 1, which can increase the heat dissipation area. The multiple groups of heat dissipation holes can allow more hot air to exchange with the outside cold air, thereby more effectively reducing the temperature inside the base body 1. The first heat dissipation holes 42 are inclined. The inclined directions of the first heat dissipation holes 42, the second heat dissipation holes 43, and the wind guide plate 46 are the same. When the air flows, due to the same inclined direction of each component, the air flow can pass through the first heat dissipation holes 42, the second heat dissipation holes 43, and flow under the guidance of the wind guide plate 46 more orderly, reducing the disorder and resistance of the air flow, thereby improving the efficiency of air circulation.
[0034] Refer to Figure 1 and Figure 3, a reinforcing component is provided at the top end of the base body 1. The reinforcing component includes a fixing groove 61 which is opened at the top end of the base body 1, providing an installation and fixing position for the reinforcing fixing plate 62. The inner wall of the fixing groove 61 is fixedly connected with the reinforcing fixing plate 62, and the outer wall of the top end of the reinforcing fixing plate 62 is fixedly connected to the inner walls of the bottom ends of the first reinforcing ring 44 and the second reinforcing ring 45, enabling the reinforcing fixing plate 62 to effectively transfer the forces received by the first reinforcing ring 44 and the second reinforcing ring 45 to the base body 1, enhancing the stability and load-bearing capacity of the overall structure. The number of the fixing grooves 61 and the reinforcing fixing plates 62 is the same, and the reinforcing fixing plates 62 are circumferentially arrayed around the center line of the base body 1, ensuring uniform and effective support and reinforcement in all directions. When the top end of the base body 1 bears various external forces and stresses, it can maintain the integrity and stability of the structure, reducing the risk of deformation and damage, thereby enhancing the load-bearing capacity and durability of the base body 1.
[0035] Working principle: During use, the entire grinding wheel is installed on the corresponding equipment or tool through the mounting hole 2 in the middle of the top end of the base body 1. When the equipment starts, the base body 1 drives the multiple groups of triangular grinding discs 3 at the bottom end to rotate at high speed. The triangular grinding discs 3 and the diamond particles inside them grind the workpiece. Since the grinding grooves 5 with opposite opening directions are provided on two adjacent groups of triangular grinding discs 3, the reaction forces generated during grinding cancel each other out or partially cancel each other out, reducing the vibration of the overall structure and ensuring the stability and accuracy of grinding.
[0036] As grinding progresses, a large amount of heat is generated. As the base body 1 rotates, the inclined first heat dissipation holes 42 generate an air flow guide, promoting the inhalation of external cold air and the discharge of internal hot air. At the same time, through the cooperation of multiple groups of second heat dissipation holes 43 and the guide plate 41, the air flow is enhanced to dissipate the heat and discharge the debris generated during grinding.
[0037] In terms of structural strength, the first reinforcing ring 44 and the second reinforcing ring 45 at the top end of the base body 1 cooperate with each other to form a double reinforcement barrier to disperse and bear external loads. The air guide plate 46 between the first reinforcing ring 44 and the second reinforcing ring 45 guides the air flow into the second heat dissipation holes 43 to assist in heat dissipation.
[0038] At the same time, through the reinforcing fixing plates 62 in multiple groups of fixing grooves 61, the forces received by the first reinforcing ring 44 and the second reinforcing ring 45 are effectively transferred to the base body 1, ensuring that the top end of the base body 1 maintains the structural integrity and stability when bearing external forces and stresses, and enhancing the load-bearing capacity and durability.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
