Description

Technical Field

[0001] This utility model relates to a saw blade, specifically a saw blade for cutting aluminum substrates. Background Technology

[0002] Aluminum substrate cutting saw blades are carbide toothed circular saw blades specifically designed for cutting aluminum alloy materials. These saw blades are commonly used for cutting aluminum profiles, pipes, bars, and radiators, and are compatible with specialized equipment such as aluminum cutting machines and sliding table saws.

[0003] Existing aluminum substrate cutting saw blades have a complex structure and unreasonable design. The blades are subjected to significant pressure when cutting aluminum substrates, and existing saw blades lack a buffering mechanism for the blades, making them easily damaged and shortening their lifespan. Furthermore, if a single blade is damaged, all blades must be replaced as a whole, which is difficult and costly. Replacing the blade also requires disassembling the corresponding parts using tools, resulting in low maintenance efficiency. Therefore, the inventors have improved the structure of the aluminum substrate cutting saw blade. Utility Model Content

[0004] The purpose of this utility model is to provide a saw blade for cutting aluminum substrates. This saw blade has a simple structure and reasonable design. The pressure generated during cutting is partially offset by the rubber ring and the bladder, which effectively reduces the damage to the moving blade and the saw teeth themselves. It can replace individual moving blades, which not only realizes tool-free disassembly and replacement of moving blades and improves maintenance efficiency, but also eliminates the need to adjust the entire mounting ring, reducing the difficulty and cost of maintenance. This solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a saw blade for cutting aluminum substrates, the saw blade including a saw disc, with saw teeth arranged on the outer side of the saw disc, wherein the saw teeth include a mounting ring and a plurality of main teeth fixed in the circumferential direction of the mounting ring, the mounting ring being fixed in the circumferential direction of the saw disc, a movable slice and an insert bar located on one side of the movable slice are provided on each of the plurality of main teeth, and a mounting groove for mounting the movable slice is formed on each of the plurality of main teeth, the movable slice including a cutting head and an inner mounting block fixed to the cutting head, through holes are provided on the main teeth and the cutting head, one end of the insert bar is inserted into the through hole, and the other end is located on the outer side of the main teeth, and a rubber ring and a bladder fixed inside the rubber ring are provided on the outer side of each insert bar.

[0006] Preferably, the inner mounting block is disposed in the mounting groove and fits against the inner wall of the mounting groove. The end of the cutting head near the inner mounting block is inserted into the mounting groove. The cutting head does not fit against the inner wall of the mounting groove, but leaves a gap. The cutting head is positioned by the inner mounting block.

[0007] Preferably, the length direction of the active slice is perpendicular to the length direction of the insert, and the insert passes through both ends of the cutting head.

[0008] Preferably, the cutting head has an inner edge wall and an outer edge wall, and a pointed head is provided between the inner edge wall and the outer edge wall to cut the aluminum substrate.

[0009] Preferably, both the rubber ring and the bladder are disposed in the mounting groove, and both the rubber ring and the bladder are arranged in a ring shape.

[0010] Preferably, the capsule is a hollow cavity structure, and the pressure inside the capsule is greater than or equal to one standard atmospheric pressure. By setting the hollow capsule, the insertion rod and the cutting head are not relatively stationary. When the cutting head is subjected to pressure, it can produce a small sway to offset part of the pressure, thereby reducing damage to the cutting head without affecting the cutting function of the cutting head.

[0011] Preferably, the rubber ring fits against the inner wall of the through hole on the cutting head, and the capsule is fixed to the outside of the insert rod. When the insert rod is installed, the through hole will exert a certain compressive force on the rubber ring and the capsule.

[0012] Preferably, a magnet is fixed inside the main tooth body, and one end of the insert rod located in the through hole is magnetically attracted to the magnet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a saw blade for cutting aluminum substrates. The saw blade includes a saw disc with saw teeth on the outer side. The overall structure is simple and reasonably designed. The saw teeth include a mounting ring and multiple main teeth fixed in the circumferential direction of the mounting ring. The mounting ring is fixed in the circumferential direction of the saw disc. Each of the multiple main teeth has a movable slice and a bar located on one side of the movable slice. Each of the multiple main teeth has a mounting groove for mounting the movable slice. The movable slice includes a cutting head and an inner mounting block fixed to the cutting head. Through holes are provided on the main teeth and the cutting head. Each bar has a rubber ring on its outer side and a bladder fixed inside the rubber ring. By setting the movable slice on the main teeth, when the saw disc drives the main teeth and the movable slice to rotate at high speed, the movable slice is subjected to pressure when cutting the aluminum substrate, and this pressure is also applied to the rubber ring and the bladder. This pressure is partially offset by the rubber ring and the bladder, thus effectively reducing the damage to the movable slice and the saw teeth themselves, extending their service life, and making it highly practical.

[0015] 2. In this utility model, one end of the insert rod is inserted into the through hole, and the other end is located on the outside of the main tooth body. A magnet is fixed inside the main tooth body. The end of the insert rod located in the through hole is magnetically attracted to the magnet. When a movable slice is damaged, the insert rod only needs to be removed from the through hole to separate the insert rod from the magnet, and then the single movable slice can be removed for replacement. This not only realizes tool-free disassembly and replacement of movable slices, improving maintenance efficiency, but also eliminates the need to adjust the entire mounting ring, thus reducing the difficulty and cost of maintenance, making it suitable for widespread use.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0026] Please see Figure 1 One embodiment of this utility model is a saw blade for cutting aluminum substrates. The saw blade for cutting aluminum substrates includes a saw disc 1, and saw teeth 2 are provided on the outer side of the saw disc 1.

[0027] Please see Figure 2 The saw tooth 2 includes a mounting ring 21 and multiple main tooth bodies 22 fixed in the circumferential direction of the mounting ring 21. The mounting ring 21 is fixed in the circumferential direction of the saw disc 1. Each of the multiple main tooth bodies 22 is provided with a movable blade 23 and a stick 24 located on one side of the movable blade 23.

[0028] Please see Figures 3 to 4Multiple main teeth 22 are each formed with mounting grooves for mounting movable slices 23. The movable slice 23 includes a cutting head 231 and an inner mounting block 232 fixed to the cutting head 231. The cutting head 231 has an inner edge wall 2311 and an outer edge wall 2312. A pointed head 2313 is provided between the inner edge wall 2311 and the outer edge wall 2312. The aluminum substrate is cut by the pointed head 2313. The inner mounting block 232 is disposed in the mounting groove and fits against the inner wall of the mounting groove. The end of the cutting head 231 near the inner mounting block 232 is inserted into the mounting groove. The cutting head 231 does not fit against the inner wall of the mounting groove, but leaves a gap. The cutting head 231 is positioned by the inner mounting block 232.

[0029] Please see Figure 5 Both the main tooth body 22 and the cutting head 231 have through holes. One end of the insert rod 24 is inserted into the through hole, and the other end is located outside the main tooth body 22. The length direction of the movable slice 23 is perpendicular to the length direction of the insert rod 24, and the insert rod 24 passes through both ends of the cutting head 231.

[0030] Please see Figure 6 Each insert 24 has a rubber ring 25 on its outer side and a bladder 26 fixed inside the rubber ring 25. Both the rubber ring 25 and the bladder 26 are set in the mounting groove and are arranged in a ring shape. The bladder 26 is a hollow cavity structure, and the pressure value inside the bladder 26 is greater than or equal to one standard atmosphere, specifically 1 to 1.08 times one standard atmosphere. By setting the hollow bladder 26, the pressure between the insert 24 and the cutting head 231 is... It is not relatively static; the cutting head 231 can produce a small wobbling after being subjected to pressure, thereby offsetting some of the pressure and reducing damage to the cutting head 231 without affecting its cutting function. The rubber ring 25 fits against the inner wall of the through hole on the cutting head 231, and the capsule 26 is fixed to the outside of the insert rod 24. When installing the insert rod 24, the through hole will exert a certain compressive force on the rubber ring 25 and the capsule 26. Therefore, when the rubber ring 25 and the capsule 26 are installed... Figure 6When positioned as shown, it can buffer the pressure on the cutting head 231. When the saw disc 1 drives the main tooth body 22 and the movable slice 23 to rotate at high speed, the movable slice 23 is subjected to pressure when cutting the aluminum substrate, and also exerts pressure on the rubber ring 25 and the bladder 26. This pressure is partially offset by the rubber ring 25 and the bladder 26, effectively reducing the damage to the movable slice 23 itself and extending its lifespan. A magnet 27 is fixed inside the main tooth body 22. One end of the insert rod 24 located in the through hole is magnetically attracted to the magnet 27, thereby fixing the insert rod 24 to the main tooth body 22. When the movable slice 23 is damaged, the corresponding single movable slice 23 can be replaced simply by removing the insert rod 24 from the through hole. This not only achieves tool-free disassembly and replacement of the movable slice 23, improving maintenance efficiency, but also eliminates the need to adjust the entire mounting ring 21, thus reducing the difficulty and cost of maintenance.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
