Technical Field
[0001] This utility model relates to the field of alloy saw blades, specifically to a high-strength thermoplastic carbide saw blade. Background Technology
[0002] High-strength thermoplastic carbide saw blades are cutting tools that combine the superior performance of carbide materials with the properties of thermoplastics. They are suitable for a variety of industrial and manufacturing environments, especially where high cutting precision and wear resistance are required.
[0003] Existing high-strength thermoplastic carbide saw blades are usually one-piece structures. When the saw teeth wear out after long-term use, the entire blade needs to be replaced, resulting in material waste. Although some saw blades can separate the saw teeth from the saw disc, they do not have a reinforcing structure, which affects the overall strength of the saw blade structure and requires further improvement.

The end of the pin away from the moving block is inserted into the corresponding slot, and the surface of the pin is in contact with the inner wall of the slot.
[0011] Preferably, the reinforcing component includes four first reinforcing blocks, which are fixed in a circular array at the edge of the first saw blade. Each of the first reinforcing blocks has a positioning protrusion fixed at the end away from the mounting hole. The second saw blade surface is fixed with four second reinforcing blocks in a circular array. Each of the second reinforcing blocks has a positioning groove on its surface.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0018] Please refer to the appendix. Figures 1-5 The present invention provides a high-strength thermoplastic carbide saw blade, comprising a first saw disc 1 and a second saw disc 2. The second saw disc 2 has saw teeth 3 fixed in a circular array at its edge. The first saw disc 1 has a mounting hole 4 in the center for mounting the saw blade on the output shaft of a motor. The first saw disc 1 and the second saw disc 2 can be detached and installed by a plug-in assembly. A reinforcing assembly is also provided between the first saw disc 1 and the second saw disc 2. A heat dissipation assembly is provided on the first saw disc 1. The insertion assembly includes four rectangular slots 5 arranged in a circular array on the first saw disc 1. Each rectangular slot 5 has a cover plate 6 fixed at its opening. A return spring 7 is fixed inside each rectangular slot 5. A movable block 8 is fixed to the end of each return spring 7 away from the mounting hole 4. An actuating piece 9 is fixed to the surface of each movable block 8. Each cover plate 6 has a slotted hole 10. The end of the actuating piece 9 passes through the slotted hole 10, and its surface is in contact with the wall of the slotted hole 10. This allows the operator to manually move the actuating piece 9, thereby controlling the movement of the movable block 8 within the rectangular slot 5. Each rectangular slot 5 has a first through hole 11 on the inner wall away from the mounting hole 4. A pin 12 is fixed to the end of each movable block 8 away from the return spring 7. The end of the pin 12 away from the movable block 8 passes through the first through hole 11, and its surface... The first saw blade 1 and the second saw blade 2 are fitted together with the wall of the first through hole 11. The inner surface of the second saw blade 2 has four slots 13 arranged in a circular array. The four slots 13 correspond to four pins 12. The end of the pin 12 away from the moving block 8 is inserted into the corresponding slot 13, and the surface of the pin 12 is fitted together with the inner wall of the slot 13. Specifically, the first saw blade 1 and the second saw blade 2 can be installed by inserting the pins 12 into the slots 13. The operator only needs to push the lever 9 to move the pins 12 out of the slots 13, thereby disassembling the first saw blade 1 and the second saw blade 2. That is, this utility model sets the saw blade as a split structure. When the saw teeth 3 wear out after long-term use and need to be replaced, only the saw teeth 3 and the second saw blade 2 need to be replaced. There is no need to replace the first saw blade 1, thereby effectively reducing material waste. The reinforcing assembly includes four first reinforcing blocks 14, which are fixed in a circular array at the edge of the first saw disc 1. Each first reinforcing block 14 has a positioning protrusion 15 fixed at its end away from the mounting hole 4. Four second reinforcing blocks 16 are fixed in a circular array on the surface of the second saw disc 2. Each second reinforcing block 16 has a positioning groove 17 on its surface. The four positioning protrusions 15 correspond one-to-one with the four positioning grooves 17. The positioning protrusions 15 are inserted into their corresponding positioning grooves 17, and their surfaces are in contact with the inner wall of the positioning grooves 17. The first reinforcing blocks 14 and the positioning protrusions... 15 is designed as an integrated structure. The first reinforcing block 14 and the positioning protrusion 15 are convex, and the second reinforcing block 16 and the positioning groove 17 are concave. Specifically, under the action of the first reinforcing block 14, the positioning protrusion 15, the second reinforcing block 16 and the positioning groove 17, the first saw disc 1 and the second saw disc 2 after the insertion installation are re-inserted, which can effectively improve the strength of the overall structure of the saw blade. The positioning protrusion 15 and the positioning groove 17 can also play a positioning role, which facilitates the quick alignment and connection of the pin 12 on the first saw disc 1 and the slot 13 on the second saw disc 2, making it convenient to use. The heat dissipation assembly includes several circular heat dissipation holes 18 and several strip heat dissipation holes 19. The circular heat dissipation holes 18 and the strip heat dissipation holes 19 are arranged in a circular array on the first saw disc 1 for heat dissipation of the saw blade.
[0019] The usage process of this utility model is as follows: First, the operator pushes the four pins 12 towards the mounting holes 4 using the actuating piece 9. At this time, the return spring 7 undergoes elastic deformation, generating elastic force. Then, the first saw disc 1 is placed inside the second saw disc 2, and the positioning protrusion 15 of the first reinforcing block 14 on the first saw disc 1 is inserted into the positioning groove 17 on the second reinforcing block 16 on the second saw disc 2. Then, the actuating piece 9 is released, causing the pins 12 to pop out and insert into the slots 13 under the elastic force of the return spring 7. With the pins 12 and slots 13 engaged, the first saw disc 1 and the second saw disc 2 can be installed. The operator only needs to push the actuating piece 9 to remove the pins 12 from the slots 13. By disassembling the first saw disc 1 and the second saw disc 2, this utility model sets the saw blade into a split structure. When the saw teeth 3 wear out after long-term use and need to be replaced, only the saw teeth 3 and the second saw disc 2 need to be replaced, without replacing the first saw disc 1, thereby effectively reducing material waste. Moreover, under the action of the first reinforcing block 14, the positioning protrusion 15, the second reinforcing block 16 and the positioning groove 17, the first saw disc 1 and the second saw disc 2 can be re-inserted after the insertion installation, thereby effectively improving the overall strength of the saw blade structure. In addition, the positioning protrusion 15 and the positioning groove 17 can also play a positioning role, which facilitates the quick alignment and connection of the pin 12 on the first saw disc 1 and the slot 13 on the second saw disc 2, making it convenient to use.
[0020] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
