Description

Technical Field

[0001] This utility model relates to the field of saw blade application technology, and in particular to a detachable and modular saw blade. Background Technology

[0002] Saw blades are commonly used cutting tools in the cutting and processing of various materials.

[0003] Traditional saw blades are mostly one-piece structures. During long-term use, if some saw teeth are worn or cracked, the entire saw blade often needs to be replaced.

[0004] This not only wastes materials and increases usage costs, but also leads to longer equipment downtime and reduced production efficiency. Moreover, different cutting tasks may have different requirements for the shape, number, and arrangement of the saw teeth on the saw blade. Integrated saw blades are difficult to flexibly adapt to various cutting scenarios. Therefore, this utility model proposes a detachable modular saw blade. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a detachable and modular saw blade, so as to solve the problems of waste caused by replacing the entire saw blade after it is damaged and difficulty in adapting to various cutting needs in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a detachable and modular saw blade, including a saw blade base, wherein multiple saw teeth are uniformly engaged and connected to the outer wall of the saw blade base; Each of the aforementioned saw teeth has an internal mounting cavity for fitting onto the outer arc wall of the saw blade base, and one or more saw teeth can be disassembled and replaced.

[0007] The present invention is further configured such that: the outer arc wall of the saw blade base is uniformly provided with multiple slots in the circumferential direction, and the outer arc wall of the saw blade base is divided into multiple connecting parts by the multiple slots to adapt to the saw teeth.

[0008] The above technical solution allows for easy installation and disassembly of the saw teeth without interference, and the connection part can determine the installation position of the saw teeth.

[0009] The present invention is further configured such that: multiple toothed blocks are fixedly connected inside the mounting cavity, and the multiple toothed blocks are respectively embedded in the toothed grooves opened on the outer arc wall of the connecting part.

[0010] The above technical solution facilitates the secure connection of the saw teeth by utilizing the tooth blocks and tooth grooves during installation, thereby increasing the connection area during use and preventing loosening.

[0011] The present invention is further configured such that: positioning blocks are symmetrically fixedly connected to the inner sidewall of the mounting cavity, and the two sets of positioning blocks are respectively engaged and connected to the two sides of the connecting part with symmetrically opened positioning holes.

[0012] The above technical solution allows the saw teeth to be stably engaged with the positioning hole by the internal positioning block when they are installed on the connecting part through the mounting cavity, thereby further strengthening the connection between the saw teeth and the connecting part.

[0013] The present invention is further configured such that: the outer arc wall of the saw tooth is provided with a diamond cutting part, and the cross-section of the cutting part is trapezoidal.

[0014] The above technical solution utilizes a diamond-made cutting part to increase the hardness of the saw teeth during cutting, and the trapezoidal bevel allows the cutting position to expand slowly.

[0015] The present invention is further configured such that: multiple air ducts are symmetrically opened on both sides of the saw toothed part, and the end faces of the multiple air ducts extend to the inclined surface of the cutting part respectively.

[0016] The above technical solution facilitates the dissipation of heat generated during the cutting process of the saw teeth, thereby reducing the temperature of the saw teeth during use.

[0017] The beneficial effects of this utility model are as follows: This invention proposes a detachable modular saw blade. By detaching the saw blade base and saw teeth, when one or more saw teeth are damaged, the damaged tooth can be removed from the saw blade base and replaced with a new one, eliminating the need to replace the entire saw blade. This significantly saves material costs and replacement time, improving production efficiency. Furthermore, because different specifications of saw teeth can be selected and combined according to different cutting needs, the saw blade can flexibly adapt to various cutting scenarios, improving its versatility.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] like Figures 1-4 As shown, a detachable modular saw blade includes a saw blade base 1. Multiple slots 11 are evenly distributed along the circumference of the outer arc wall of the saw blade base 1, dividing the outer arc wall of the saw blade base 1 into multiple connecting portions 12 to accommodate saw teeth 2. The slots 11 facilitate the installation and disassembly of the saw teeth 2 without interference, and the connecting portions 12 determine the installation position of the saw teeth 2. Multiple saw teeth 2 are evenly engaged and connected to the outer wall of the saw blade base 1. The outer arc wall is provided with a diamond cutting part 21, and the cross-section of the cutting part 21 is trapezoidal. The diamond cutting part 21 can improve the hardness of the saw tooth 2 during cutting, and the trapezoidal bevel allows the cutting position to be gradually expanded. Multiple air ducts 22 are symmetrically opened on both sides of the saw tooth 2. The end faces of the multiple air ducts 22 extend to the bevel of the cutting part 21, which facilitates the heat generated by the saw tooth 2 during cutting and thus reduces the temperature of the saw tooth 2 during use.

[0022] like Figures 1-5 As shown, each of the multiple saw teeth 2 has an internal mounting cavity 23 for fitting onto the outer arc wall of the saw blade base 1. This allows for the disassembly and replacement of one or more saw teeth 2. Multiple tooth blocks 24 are fixedly connected inside the mounting cavity 23, and these tooth blocks 24 are respectively embedded in the tooth grooves 13 opened on the outer arc wall of the connecting part 12. This facilitates a secure connection between the saw teeth 2 and the tooth grooves 13 during installation, increasing the connection area and preventing loosening. Positioning blocks 25 are symmetrically fixedly connected to the inner side wall of the mounting cavity 23, and two sets of positioning blocks 25 are respectively engaged with positioning holes 14 symmetrically opened on both sides of the connecting part 12. This ensures that when the saw teeth 2 are installed on the connecting part 12 through the mounting cavity 23, they can be stably engaged with the positioning holes 14 using the internal positioning blocks 25, further strengthening the connection between the saw teeth 2 and the connecting part 12.

[0023] When using this invention, if wear or damage is found on a certain saw tooth 2, stop the machine and ensure that the sawing equipment is in a safe state. Use tools to remove the damaged saw tooth 2 from the saw blade base 1. Then, take a new saw tooth 2 of the same specifications and use the mounting cavity 23 to fit it onto the connecting part 12, so that the tooth block 24 and the tooth groove 13 are embedded and fixed. The positioning block 25 is engaged and connected to the inside of the positioning hole 14 to achieve a firm connection and fixation. After checking that everything is correct, the sawing equipment can be restarted to continue the cutting work.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
