[0025] With reference to Figure 1 and Figure 2 , the two sides of the outer side wall of the saw blade 1 are fixedly connected with thickening discs 7 around the first through hole 5. The thickening discs 7 can maximize the strength of the central region of the saw blade 1, thereby dispersing the stress, especially the torque and impact force, that the saw blade 1 receives during cutting, and minimizing the deformation or damage of the saw blade 1 at the center.

[0026] With reference to Figure 2 and Figure 3 , the side of the mounting flange 3 and the fixing flange 4 close to the thickening disc 7 is fixedly connected with a matching embedding groove 8, and the four sides of the saw blade 1, the thickening disc 7, the mounting flange 3 and the fixing flange 4 are provided with flange connecting holes 9. The four sides of the outer side wall of the thickening disc 7 away from the saw blade 1 are provided with limiting grooves 10, and the four sides of the inner side wall of the embedding groove 8 are fixedly connected with limiting strips 11 matched with the limiting grooves 10. When the saw blade 1 and the mounting flange 3 are sleeved on the driving shaft 2;

[0027] The saw blade 1 and the mounting flange 3 are rotated to align the limiting grooves 10 and the limiting strips 11, and then the fixing flange 4, the saw blade 1 and the mounting flange 3 are attached to each other. During the attachment process, the limiting strips 11 are smoothly inserted into the limiting grooves 10. Through the cooperation of the thickening disc 7 and the embedding groove 8, and the mutual restriction of the limiting grooves 10 and the limiting strips 11, the saw blade 1 is accurately positioned and limited in the axial and circumferential directions.

[0028] During cutting, the limiting grooves 10 and the limiting strips 11 can increase the contact area of the inner side wall of the embedding groove 8 and the thickening disc 7, so that the stress can be dispersed to a larger area, and the shape and structure can guide the stress to be distributed in the direction of the limiting groove 10, further reducing the risk of excessive local stress and preventing the saw blade from being damaged or deformed.

[0029] With reference to Figure 1 , Figure 2 and Figure 3 , the outer side wall of the mounting flange 3 and the fixing flange 4 away from the embedding groove 8 is provided with a counterbore 12 around the flange connecting hole 9.

At this time, the nuts are located in the counterbores 12 and do not protrude from the surface of the flanges, which not only ensures the firmness of the connection, but also makes the appearance of the entire device more flat, reducing the possibility of collisions or other safety hazards caused by the protruding nuts during use.

[0030] The outer side wall of the mounting flange 3 and the fixing flange 4 is provided with a heat dissipation groove 13 around the side away from the embedding groove 8, which can increase the surface area of the mounting flange 3 and the fixing flange 4, and further increase the heat exchange efficiency between the mounting flange 3 and the fixing flange 4 and the external air;

[0032] The sealing ring 16 is an elastic sealing ring, when the saw blade 1, the mounting flange 3 and the fixing flange 4 are mutually adhered and fixed, the reinforcing ring 14 is inserted into the sealing groove 15, and at the same time, the sealing ring 16 is compressed to fill the small gap between the inner side wall of the sealing groove 15 and the reinforcing ring 14, thereby preventing the external dust, debris, moisture and the like from entering the connection part of the saw blade 1, the mounting flange 3 and the fixing flange 4, reducing the wear and corrosion caused by impurities, and prolonging the service life of the equipment.

[0033] In use, the saw blade 1 is accurately sleeved on the driving shaft 2 through the first perforation 5 in the center of the saw blade 1, to ensure that the saw blade 1 can freely rotate on the driving shaft 2 and the position is approximately correct, and the mounting flange 3 is also sleeved on the driving shaft 2 through the second perforation 6 in the center of the mounting flange 3, at this time, the saw blade 1 and the mounting flange 3 are in a relatively adjustable state on the driving shaft 2;

[0034] The saw blade 1 and the mounting flange 3 are rotated to the positions where the limiting groove 10 and the limiting strip 11 are aligned with each other, and then the fixing flange 4, the saw blade 1 and the mounting flange 3 are mutually adhered, in the adhering process, the limiting strip 11 is smoothly inserted into the limiting groove 10, through the cooperation of the thickening disc 7 and the embedding groove 8, and the mutual restriction of the limiting groove 10 and the limiting strip 11, the saw blade 1 is accurately positioned and limited in the axial and circumferential directions, which prevents the displacement or shaking of the saw blade 1 in the working process due to stress, thereby ensuring the cutting accuracy and safety;

[0035] At the same time, the reinforcing ring 14 of the outer side wall of the saw blade 1 is accurately inserted into the sealing groove 15 of the mounting flange 3 and the fixing flange 4 close to the embedding groove 8, and forms a close abutment with the sealing ring 16 in the sealing groove 15;

[0036] Then, the bolt is passed through the flange connecting hole 9, the nuts are screwed on both ends of the bolt and are screwed to fit the mounting flange 3 and the fixed flange 4 respectively, thereby completing the fixation of the saw blade 1, the mounting flange 3 and the fixed flange 4, at this time, the nuts are located in the counterbores 12 and do not protrude from the flange surface, which not only ensures the firmness of the connection, but also makes the appearance of the entire device more flat, reduces the collision or other safety hazards that may be caused by the protruding nuts during use, and also facilitates the installation and operation of the equipment in a small space;

[0037] In use, the driving shaft 2 drives the mounting flange 3, the saw blade 1 and the fixed flange 4 to rotate to cut the material, in the cutting process, the saw blade 1 will generate a large amount of heat due to friction with the material during cutting, which will be conducted to the mounting flange 3 and the fixed flange 4 through the saw blade 1, the heat dissipation groove 13 increases the surface area of the flange, so that the heat can be dissipated more quickly to the surrounding air, effectively reducing the temperature of the saw blade 1, the mounting flange 3 and the fixed flange 4, and avoiding the problems of annealing, deformation or other performance degradation of the saw blade 1 due to overheating, thereby ensuring the normal operation and continuous working ability of the equipment.
