[0002] A circular saw blade is a cutting tool used for processing blanks of materials such as stone, wood, metal, and plastic. A high-speed circular saw blade is a saw blade containing a large amount of elements such as carbon, tungsten, molybdenum, and vanadium, and is widely used in the construction and furniture industries. Saw blades of different specifications are required to cut objects of different sizes. When cutting a large object, a larger distance between the saw teeth of the saw blade is required to ensure the cutting efficiency of the saw blade. When cutting small objects, a smaller distance between the saw blades is required.

[0003] When the circular saw blade is cutting, the circular saw blade is easily broken by the material to be cut and splashes around, causing injury to the user. Content of the Utility Model

A fixing hole is provided at the middle position on one side of the alloy saw blade matrix. First reinforcing rings are provided on the inner sides of both sides of the alloy saw blade matrix. A plurality of heat dissipation holes are arranged around the fixing hole on one side of the alloy saw blade matrix. Second reinforcing rings are installed on the outer sides of both sides of the alloy saw blade matrix. An impact-resistant saw blade ring is installed on the outer surface of the alloy saw blade matrix. A plurality of wear-resistant saw teeth are arranged around the fixing hole on the outer surface of the impact-resistant saw blade ring.

[0006] Preferably, one end of the top of the wear-resistant saw tooth is arc-shaped.

[0007] Preferably, the intervals of the plurality of heat dissipation holes on the alloy saw blade matrix and the plurality of wear-resistant saw teeth on the impact-resistant saw blade ring are the same.

[0008] Preferably, the alloy saw blade matrix and the impact-resistant saw blade ring are connected by welding.

[0009] Preferably, the first reinforcing ring and the second reinforcing ring have the same strength.

[0010] Compared with the prior art, the beneficial effects of the present utility model are: This circular saw blade that prevents breakage forms a high-strength circular saw blade through the alloy saw blade matrix, the first reinforcing ring, the second reinforcing ring, and the impact-resistant saw blade ring, improving the strength of the circular saw blade, preventing the circular saw blade from being easily broken and having a short service life. At the same time, heat dissipation holes are provided on the alloy saw blade matrix to prevent the material of the alloy saw blade matrix from becoming brittle due to high temperature during the cutting process.

[0014] 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.

[0015] Please refer to Figure 1-2 , an embodiment provided by the present utility model: An anti - breakage circular saw blade, including an alloy saw blade substrate 1, a fixing hole 2 is opened at the middle position on one side of the alloy saw blade substrate 1, and the circular saw blade is installed on a cutting tool through the fixing hole 2. First reinforcing rings 3 are arranged on the inner sides of both sides of the alloy saw blade substrate 1. A plurality of heat dissipation holes 4 are arranged around the fixing hole 2 on one side of the alloy saw blade substrate 1. The temperature of the alloy saw blade substrate 1 during operation is reduced through the heat dissipation holes 4. Second reinforcing rings 5 are installed on the outer sides of both sides of the alloy saw blade substrate 1. The strength of the alloy substrate is improved through the cooperation between the first reinforcing ring 3 and the second reinforcing ring 5. An impact - resistant saw blade ring 6 is installed on the outer surface of the alloy saw blade substrate 1. The buffering force of the circular saw blade is reduced through the impact - resistant saw blade ring 6. A plurality of wear - resistant saw teeth 7 are arranged around the fixing hole 2 on the outer surface of the impact - resistant saw blade ring 6.

[0016] In this embodiment, one end of the top of the wear - resistant saw teeth 7 is arc - shaped. When the arc - shaped wear - resistant saw teeth 7 are cutting, the wear - resistant degree of the arc - shaped saw teeth is relatively high.

[0017] In this embodiment, the intervals between the plurality of heat dissipation holes 4 on the alloy saw blade substrate 1 and the plurality of wear - resistant saw teeth 7 on the impact - resistant saw blade ring 6 are the same. The heat generated during the cutting of the wear - resistant saw teeth 7 can be introduced into the alloy saw blade substrate 1 through the impact - resistant saw blade ring 6 and discharged through the heat dissipation holes 4.

[0018] In this embodiment, the alloy saw blade substrate 1 and the impact - resistant saw blade ring 6 are connected by welding to prevent the impact - resistant saw blade ring 6 from falling off the alloy saw blade substrate 1 during the cutting of the circular saw blade.

[0019] In this embodiment, the first reinforcing ring 3 and the second reinforcing ring 5 have the same strength. The alloy saw blade substrate 1 increases its strength through the first reinforcing ring 3 and the second reinforcing ring 5, preventing the alloy saw blade substrate 1 from cracking.
