Description

Technical Field

[0001] This utility model belongs to the field of grinding wheel technology, specifically relating to a novel high-speed explosion-proof resin grinding wheel. Background Technology

[0002] A grinding wheel is a circular, bonded abrasive tool with a central through-hole, made by mixing abrasive and a binder, pressing, drying, and firing the mixture. Grinding wheels are the most widely used and extensive type of abrasive tool. They rotate at high speeds and are used for roughing, semi-finishing, finishing, grooving, and cutting of workpieces' outer and inner diameters, planes, and various profiles. Grinding wheels can be classified according to the type of binder used, including resin-bonded grinding wheels, rubber-bonded grinding wheels, metal-bonded grinding wheels, ceramic-bonded grinding wheels, electrocoated grinding wheels, and single-layer metal-coated grinding wheels. Resin-bonded grinding wheels are made using phenolic resin, epoxy resin, polyurethane resin, polyvinyl alcohol resin, etc., as binders.

[0003] Resin grinding wheels have the characteristics of high strength, high elasticity, impact resistance and robustness, but poor heat resistance. Therefore, how to dissipate heat from numerical grinding wheels is an urgent problem to be solved. To solve this problem, a new type of high-speed explosion-proof resin grinding wheel is proposed. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a novel high-speed explosion-proof resin grinding wheel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel high-speed explosion-proof resin grinding wheel, comprising a grinding wheel base and a mounting ring. The grinding wheel base has multiple ventilation channels. The front side of the grinding wheel base has multiple first air holes communicating with the ventilation channels, and the back side of the grinding wheel base has multiple second air holes communicating with the ventilation channels. The mounting ring is fixedly connected to the center of the grinding wheel base. Multiple pressure blocks fixedly connected to the mounting ring are fixedly connected to both sides of the grinding wheel base. Multiple positioning holes are opened on both sides of the mounting ring. A wheel ring is provided on the outer ring of the grinding wheel base.

[0006] Preferably, the outer diameter of the wheel ring is 100-500mm, and the thickness of the grinding wheel base and the wheel ring is 1-6mm.

[0007] Preferably, the raw material of the wheel ring is phenolic resin powder, corundum abrasive, or silicon carbide abrasive.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention allows air to pass through the first air hole, the second air hole, and the ventilation channel through the grinding wheel base, which can remove the heat generated during operation, resulting in better heat dissipation and strong practicality. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1-4 This utility model provides the following technical solution: A novel high-speed explosion-proof resin grinding wheel, comprising a grinding wheel base 1 and a mounting ring 6. The grinding wheel base 1 has multiple ventilation channels 8. The front side of the grinding wheel base 1 has multiple first air holes 3 communicating with the ventilation channels 8. The back side of the grinding wheel base 1 has multiple second air holes 7 communicating with the ventilation channels 8. The mounting ring 6 is fixedly connected to the center of the grinding wheel base 1. Multiple pressure blocks 5 are fixedly connected to the mounting ring 6 on both sides of the grinding wheel base 1. Multiple positioning holes 2 are opened on both sides of the mounting ring 6. A wheel ring 4 is provided on the outer ring of the grinding wheel base 1.

[0018] Specifically, the outer diameter of the wheel ring 4 is 100-500mm, and the thickness of the grinding wheel base 1 and the wheel ring 4 is 1-6mm.

[0019] Specifically, the raw materials for the wheel ring 4 are phenolic resin powder, corundum abrasive, and silicon carbide abrasive.

[0020] The working principle and usage process of this utility model are as follows: When using the grinding wheel of this patent for processing, the mounting ring 6 can be driven to rotate through the positioning hole 2 on the mounting ring 6, thereby driving the grinding wheel base 1 to rotate. The grinding wheel base 1 drives the wheel ring 4 to rotate. During the rotation of the grinding wheel base 1, air enters the ventilation channel 8 from the first air hole 3 and is then discharged from the second air hole 7. In this process, the heat generated when the grinding wheel is working can be dissipated. Compared with traditional grinding wheels, the heat dissipation effect is better and the practicality is stronger.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
