Description

Technical Field

[0001] The present application relates to the technical field of grinding wheels, and in particular to a grinding wheel with good heat dissipation effect. Background Art

[0002] Grinding wheels are the most important type of grinding tools in grinding processing. Grinding wheels are porous bodies made by adding a binder to abrasives, pressing, drying and sintering.

[0003] An existing patent (publication number: CN219882233U) discloses a fast-heating grinding wheel, comprising a grinding wheel body with an axial hole at its center; a shaft sleeve secured within the axial hole; heat dissipation chucks mounted on both the front and rear ends of the shaft sleeve; the inner sides of the heat dissipation chucks bonded to the surface of the grinding wheel body; and fixed rods mounted around the circumference of the heat dissipation chucks, which are secured to the surface of the grinding wheel body. This invention utilizes heat dissipation grooves to increase the contact area between the heat dissipation chuck and the air, enhancing the heat dissipation effect during rotation. Furthermore, the provision of annular grooves and heat sinks further increases the contact area between the heat dissipation chuck and the air, thereby improving heat dissipation and reducing heat transfer to equipment such as grinders and cutters, thereby protecting these devices. It also increases the cooling rate of the grinding wheel body, reducing damage to the grinding wheel body caused by high temperatures to a certain extent.

[0004] However, the above-mentioned grinding wheels increase the heat dissipation area and improve the heat dissipation effect by opening heat dissipation grooves, setting annular grooves and heat sinks on the grinding wheel body. Most of these designs rely on passive heat dissipation, that is, relying on natural convection of air or air flow around the grinding wheel to remove heat, and the heat dissipation efficiency is limited. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present application provides a grinding wheel with good heat dissipation effect, which has the advantages of good heat dissipation efficiency and solves the problems raised in the background technology.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a grinding wheel with good heat dissipation effect, comprising a mounting ring, a heat insulation ring fixedly connected to the outer surface of the mounting ring, a cooling ring fixedly connected to the outer surface of the heat insulation ring, a plurality of circumferentially arranged cooling fins fixedly connected to the outer surface of the cooling ring, a sand disk connected to the outer surface of the cooling ring, and each cooling fin fixedly embedded in the sand disk;

[0007] The front and back sides of the cooling ring are fixedly connected with a plurality of circumferentially arranged air boxes, and both ends of the air boxes are provided with an air inlet and an air outlet respectively, and the area of ​​each air inlet is larger than that of the air outlet.

[0008] Through the above scheme, through the combined design of the mounting ring, the heat insulation ring, the cooling ring and the cooling fins, and in conjunction with the air inlet and outlet settings of the air box, active heat dissipation is achieved by utilizing the airflow generated by the rotation during the rotation of the grinding wheel. This design not only accelerates the circulation efficiency of the gas on the surface of the cooling ring, but also significantly improves the overall heat dissipation effect, so that the grinding wheel can more effectively reduce the temperature during operation and extend its service life. The cooling ring and cooling fins are made of copper alloy material, which has good thermal conductivity and light weight, which not only improves the heat dissipation effect but also reduces the overall weight of the grinding wheel. The rib design on the surface of the cooling fin not only improves the friction coefficient, but also ensures the mechanical strength of the sand disc, making the grinding wheel more durable during the grinding process. The heat insulation ring is made of glass fiber reinforced plastic, which effectively prevents heat transfer, protects the grinding wheel machine from high temperature, and further improves the safety and reliability of the grinding wheel.

[0009] Furthermore, the cooling ring and each cooling fin are made of copper alloy material.

[0010] The above solution has good thermal conductivity and light weight, which can improve the heat dissipation effect and reduce the overall weight.

[0011] Furthermore, the mounting ring is made of stainless steel.

[0012] Through the above scheme and the above arrangement, the strength and durability of the mounting ring can be improved, ensuring the stability and safety of the grinding wheel during use.

[0013] Furthermore, a special-shaped hole is provided at the center of the mounting ring.

[0014] Through the above scheme and the above arrangement, the installation of the whole and the grinding machine can be achieved.

[0015] Furthermore, a plurality of ribs are fixedly connected to the surface of each cooling fin.

[0016] Through the above solution, by providing the ribs, the friction coefficient can be increased, thereby ensuring the mechanical strength of the sand tray.

[0017] Furthermore, the thermal insulation ring is made of glass fiber reinforced plastic.

[0018] Through the above solution, heat transfer can be effectively prevented and the grinding machine can be protected from high temperature.

[0019] Furthermore, each of the cooling fins is bent.

[0020] Through the above solution and the above arrangement, the contact area between the cooling fins and the sand tray can be increased, thereby improving the heat dissipation effect.

[0021] Furthermore, hard abrasive grains are evenly distributed in the sand tray.

[0022] Through the above scheme, the grinding needs under different materials and processing requirements can be met.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] The grinding wheel with good heat dissipation effect is designed with a combination of an installation ring, an insulation ring, a cooling ring and cooling fins, and is equipped with an air inlet and an air outlet of an air box, so that active heat dissipation is achieved by using the airflow generated by the rotation during the rotation of the grinding wheel. This design not only accelerates the circulation efficiency of the gas on the surface of the cooling ring, but also significantly improves the overall heat dissipation effect, so that the grinding wheel can more effectively reduce the temperature during operation and extend its service life. The cooling ring and cooling fins are made of copper alloy material, which has good thermal conductivity and light weight, which not only improves the heat dissipation effect but also reduces the overall weight of the grinding wheel. The rib design on the surface of the cooling fin not only improves the friction coefficient, but also ensures the mechanical strength of the sand disc, making the grinding wheel more durable during the grinding process. The insulation ring is made of glass fiber reinforced plastic, which effectively prevents heat transfer, protects the grinding wheel machine from high temperature, and further improves the safety and reliability of the grinding wheel.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1 、 Figure 2 and Figure 4 In this embodiment, a grinding wheel with good heat dissipation effect includes a mounting ring 1, which is made of stainless steel. Through the above configuration, the strength and durability of the mounting ring 1 can be improved, ensuring the stability and safety of the grinding wheel during use. A special-shaped hole 9 is opened at the center of the mounting ring 1. Through the above configuration, the installation of the whole to the grinding machine can be achieved. The outer surface of the mounting ring 1 is fixedly connected to a heat insulation ring 2, the outer surface of the heat insulation ring 2 is fixedly connected to a cooling ring 3, the outer surface of the cooling ring 3 is fixedly connected to a plurality of circumferentially arranged cooling fins 4, the outer surface of the cooling ring 3 is connected to a sand disk 5, and each cooling fin 4 is fixedly embedded in the sand disk 5.

[0033] See also Figure 1 、 Figure 3 and Figure 4 The insulation ring 2 is made of glass fiber reinforced plastic, which can effectively prevent heat transfer and protect the grinding wheel from high temperature. The cooling ring 3 and each cooling fin 4 are made of copper alloy material, which has good thermal conductivity and light weight, can improve the heat dissipation effect and reduce the overall weight. A plurality of ribs 10 are fixedly connected to the surface of each cooling fin 4. The setting of the ribs 10 can increase the friction coefficient, thereby ensuring the mechanical strength of the sand disc 5.

[0034] See also Figure 1 、 Figure 3 and Figure 4 The front and back sides of the cooling ring 3 are fixedly connected with a plurality of circumferentially arranged air boxes 6. An air inlet 7 and an air outlet 8 are respectively provided at both ends of the air box 6. The area of ​​each air inlet 7 is larger than that of the air outlet 8. Through the above arrangement, it is possible to realize that during the overall rotation, the rotation causes the airflow to be compressed through the air inlet 7 and then flows out to the surface of the cooling ring 3 through the air outlet 8, thereby accelerating the gas circulation efficiency on the surface of the cooling ring 3 and improving the cooling effect.

[0035] See also Figure 1 、 Figure 2 and Figure 3 Each cooling fin 4 is bent. Through the above arrangement, the contact area between the cooling fin 4 and the sand disk 5 can be increased, thereby improving the heat dissipation effect. Hard abrasive particles are evenly distributed in the sand disk 5, which can meet the grinding needs under different materials and processing requirements.

[0036] In this embodiment, a grinding wheel with good heat dissipation effect is designed by installing a combination of a ring 1, an insulation ring 2, a cooling ring 3 and cooling fins 4, and coordinating with the air inlet 7 and the air outlet 8 of the air box 6, so that active heat dissipation is achieved by using the air flow generated by the rotation during the rotation of the grinding wheel. This design not only accelerates the circulation efficiency of the gas on the surface of the cooling ring 3, but also significantly improves the overall heat dissipation effect, so that the grinding wheel can more effectively reduce the temperature during operation and extend its service life. The cooling ring 3 and the cooling fins 4 are made of copper alloy material, which has good thermal conductivity and light weight, which not only improves the heat dissipation effect but also reduces the overall weight of the grinding wheel. The ribs 10 on the surface of the cooling fins 4 not only improve the friction coefficient, but also ensure the mechanical strength of the sand disc 5, making the grinding wheel more durable during the grinding process. The insulation ring 2 is made of glass fiber reinforced plastic, which effectively prevents heat transfer, protects the grinding wheel machine from high temperature, and further improves the safety and reliability of the grinding wheel.

[0037] The working principle of the above embodiment is as follows: first, the grinding wheel is fixedly connected to the grinding machine through the special-shaped hole 9 on the mounting ring 1. When the grinding wheel starts to work, the grinding wheel starts to rotate as the grinding machine is driven. During the rotation, due to the special design of the air box 6, the area of ​​its air inlet 7 is larger than the air outlet 8, so that the air flow is compressed when passing through the air inlet 7, and then flows out to the surface of the cooling ring 3 through the air outlet 8. This design cleverly utilizes the air flow generated by the rotation of the grinding wheel to achieve the effect of active heat dissipation. As the air flow continues to circulate, the gas circulation efficiency on the surface of the cooling ring 3 is significantly improved, thereby effectively taking away the sand. The wheel generates heat during operation. At the same time, the cooling ring 3 and the cooling fins 4 are made of copper alloy. Copper alloy has good thermal conductivity and can quickly conduct the heat inside the grinding wheel to the surface of the cooling ring 3 and the cooling fins 4, and then carry it away through the airflow. In addition, the copper alloy is lighter in weight, which helps to reduce the overall weight of the grinding wheel and improve its utilization efficiency. Finally, the thermal insulation ring 2 is made of glass fiber reinforced plastic, which effectively prevents the transfer of heat, isolates the heat generated by the grinding wheel inside, and prevents it from being transferred to the grinding machine, thereby protecting the normal operation of the grinding machine and improving the safety and reliability of the grinding wheel.
