Description

Technical Field

[0001] This utility model relates to the field of double-tooth saw blade technology, specifically to a durable double-tooth high-speed steel band saw blade. Background Technology

[0002] Double-tooth high-speed steel band saw blades are tools specifically designed for efficient cutting of metal materials. They are made of high-speed steel, a material widely used in cutting tools due to its excellent hardness, wear resistance, and heat resistance, which improves the durability and cutting efficiency of the saw blade.

[0003] Existing double-tooth high-speed steel band saw blades generally use a linkage structure to increase the distance between the mounting rods at both ends of the saw body, so that the saw blade body can be locked together. However, the saw blade body is prone to sliding on the mounting rods at both ends of the saw body during use. Because the saw blade body is relatively thin and its own strength is insufficient, it is easy to deform or even break when subjected to external pressure, which affects the service life of the saw blade body and the work efficiency of the workers. Utility Model Content

[0004] In view of the problems existing in the current double-tooth high-speed steel band saw blade, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a durable double-tooth high-speed steel band saw blade, which solves the problem that the saw blade body is prone to sliding on the mounting rods at both ends of the saw body during use. Because the saw blade body is relatively thin and its own strength is insufficient, it is easy to deform or even break when subjected to external pressure, which affects the service life of the saw blade body and the work efficiency of the workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A durable double-tooth high-speed steel band saw blade includes a saw blade body and a saw body. Anti-oxidation layers are fixedly connected to both end sidewalls of the saw blade body. A wear-resistant layer is fixedly connected to the sidewall of each anti-oxidation layer. A reinforcing sleeve is fixedly fitted onto the sidewall of the saw blade body. A first mounting opening is provided on both end sidewalls of the saw blade body. A second mounting opening is provided on the surface of the reinforcing sleeve corresponding to the first mounting opening. Mounting rods are fixedly connected to both end sidewalls of the saw body. A limiting plate is fixedly connected to one end of each mounting rod. The rod wall of each mounting rod is respectively engaged with both ends of the saw blade body through the first and second mounting openings. Mounting sleeves are fixedly connected to one end sidewall of the reinforcing sleeve corresponding to the two second mounting openings. Internal threads are provided inside each mounting sleeve. A threaded sleeve is threaded onto each mounting sleeve through the corresponding internal threads. Multiple first saw teeth are fixedly connected to one end sidewall of the saw blade body, and multiple second saw teeth are fixedly connected to one end sidewall of the saw blade body.

[0007] Preferably, each of the threaded sleeves is fixedly connected to a mounting plate on its sidewall, and each of the mounting plates is fixedly connected to an anti-slip rubber pad on its sidewall.

[0008] Preferably, the surface of the saw blade body is provided with multiple heat dissipation holes.

[0009] Preferably, each of the first saw teeth has a chip removal groove on its surface.

[0010] Furthermore, the antioxidant layer is an organosilicon resin coating.

[0011] Preferably, the wear-resistant layer is a tungsten carbide coating.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model utilizes a reinforcing sleeve to enhance the mechanical strength and hardness of the saw blade body. Two mounting rods at each end of the saw body connect to corresponding first and second mounting ports, allowing the saw body to movably engage with the saw blade body and the reinforcing sleeve. Rotating the threaded sleeve connects the mounting sleeve to the threaded sleeve via its internal thread. One end of the mounting plate engages with the side wall of the corresponding limiting plate via an anti-slip rubber pad, making the connection between the saw blade body and the saw body more secure. This prevents the saw blade body from moving along the wall of the mounting rod through the first mounting port during use, thus avoiding deformation or even breakage during operation. This improves worker efficiency and extends the service life of the saw blade body.

[0014] 2. This utility model utilizes a reinforcing sleeve to enhance the mechanical strength of the saw blade body, and further utilizes a tungsten carbide coating with high hardness and high wear resistance. Through processes such as arc spraying, tungsten carbide powder is sprayed onto the surface of the saw blade to form a coating with high hardness and wear resistance, thereby improving the rigidity and service life of the saw blade body.

[0015] 3. This utility model utilizes the setting of a first saw tooth, a second saw tooth, and a chip removal groove to arrange the first and second saw teeth on the saw blade body in a paired manner. This design helps to balance the cutting force, reduce the vibration and wear of the saw blade, and the chip removal groove helps to remove chips and improve cutting efficiency, enabling the first and second saw teeth to cut various materials quickly and accurately.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a durable double-tooth high-speed steel band saw blade.

[0025] This utility model provides, for example Figure 1-4 The image shows a durable double-tooth high-speed steel band saw blade, comprising a saw blade body 1 and a saw body 2. Anti-oxidation layers 3 are fixedly connected to both side walls of the saw blade body 1, and a wear-resistant layer 4 is fixedly connected to the side wall of each anti-oxidation layer 3. Reinforcing sleeves 5 are fixedly fitted onto the side walls of the saw blade body 1. First mounting openings 6 are provided on both side walls of the saw blade body 1, and second mounting openings 7 are provided on the surface of the reinforcing sleeves 5 corresponding to the first mounting openings 6. Mounting rods 8 are fixedly connected to both side walls of the saw body 2, and one end of each mounting rod 8 is fixed... A limiting plate 9 is connected. The rod wall of each mounting rod 8 is respectively engaged with both ends of the saw blade body 1 through the first mounting port 6 and the second mounting port 7. One side wall of the reinforcing sleeve 5 is fixedly connected to the two second mounting ports 7 respectively. Each mounting sleeve 10 has an internal thread 11. Each mounting sleeve 10 is threaded with a threaded sleeve 12 through the corresponding internal thread 11. The side wall of each threaded sleeve 12 is fixedly connected to a mounting plate 15. The side wall of each mounting plate 15 is fixedly connected to an anti-slip rubber pad 16.

[0026] By using a reinforcing sleeve 5 to enhance the mechanical strength of the saw blade body 1, and by using a tungsten carbide coating with high hardness and high wear resistance through processes such as arc spraying, tungsten carbide powder can be sprayed onto the surface of the saw blade to form a coating with high hardness and wear resistance, thereby improving the rigidity and service life of the saw blade body 1.

[0027] By using two mounting rods 8 at each end of the saw body 2 to connect with the corresponding first mounting port 6 and second mounting port 7, the saw body 2 is movably connected to the saw blade body 1 and the reinforcing sleeve 5. By rotating the screw sleeve 12, the mounting sleeve 10 is threadedly connected to the screw sleeve 12 through the internal thread 11. One end of the mounting plate 15 is engaged with the side wall of the corresponding limiting plate 9 through the anti-slip rubber pad 16. This makes the connection between the saw blade body 1 and the saw body 2 more secure, preventing the saw blade body 1 from moving on the rod wall of the mounting rod 8 through the first mounting port 6 during use, which could lead to deformation or even breakage of the saw blade body 1 during operation, thus improving the work efficiency of the workers.

[0028] In order to dissipate the heat generated by the friction between the saw blade body 1 and the material during operation, such as Figure 1 As shown, the surface of the saw blade body 1 has multiple heat dissipation holes 17.

[0029] By utilizing multiple heat dissipation holes 17, the heat generated by the friction between the saw blade body 1 and the material during operation is quickly dissipated, thus preventing the heat generated by friction from affecting the service life of the first saw tooth 13, the second saw tooth 14, and the saw blade body 1.

[0030] In order to resist oxidation in the atmosphere, such as Figure 2 As shown, the antioxidant layer 3 is an organosilicon resin coating.

[0031] Silicone resin coating is a new type of steel protective material that can meet the protection requirements of high temperature and extreme climate environments, while also exhibiting excellent weather resistance and chemical resistance. The high strength and high viscosity of silicone resin can form a protective layer to protect the saw blade body1 from atmospheric oxidation.

[0032] Finally, in order to improve cutting efficiency, such as Figure 1 and 2 As shown, a plurality of first saw teeth 13 are fixedly connected to one side wall of the saw blade body 1, and a plurality of second saw teeth 14 are fixedly connected to one side wall of the saw blade body 1. The wear-resistant layer 4 is a tungsten carbide coating, and a chip removal groove 18 is provided on the surface of each first saw tooth 13.

[0033] By setting the first saw tooth 13, the second saw tooth 14 and the chip removal groove 18, the first saw tooth 13 and the second saw tooth 14 on the saw blade body 1 are arranged in pairs. This design helps to balance the cutting force, reduce the vibration and wear of the saw blade, and the chip removal groove 18 helps to remove chips and improve cutting efficiency, which can help the first saw tooth 13 and the second saw tooth 14 to cut a variety of materials quickly and accurately.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
