Technical Field

[0001] The utility model relates to the technical field of alloy saw blades, in particular to a high-performance combined humpback toothed alloy saw blade. Background Art

[0002] Saw blades are a general term for thin circular cutting tools used to cut solid materials. Alloy saw blades are usually used to cut various furniture, artificial boards, aluminum alloys, aluminum profiles, radiators, plastics, plastic steel and other materials.

[0003] Most of the existing humpback tooth alloy saw blades are of an integrated structure. The alloy saw blades will cause wear during use. If the saw teeth are worn, the entire carbide saw blade needs to be replaced, resulting in high replacement costs and waste of resources. In addition, the existing alloy saw blades will generate a lot of heat during operation. After long-term use, the temperature will rise and the saw blade will easily stick to the material, causing the saw to jam, posing a safety hazard. Utility Model Content

[0011] Preferably, the guide plates and guide grooves are evenly distributed in a circular array around the center of the second mounting plate, and one end of the guide groove is connected to the air hole.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a mounting plate 1, a mounting plate 2, a fixed column, a rotating plate, a limit plate and a slider. By pushing the slider to rotate the rotating plate until the notch is moved to the fixed column, the mounting plate 2 can be separated from the mounting plate 1, thereby realizing convenient disassembly of the saw blade, effectively reducing the difficulty of replacing the saw blade, and reducing the waste generated when replacing the saw blade. The limit plate is moved into the fixed groove by rotating the rotating plate.

[0023] The outer diameters of the mounting disc 1 and the mounting disc 2 3 are the same. The mounting disc 1 and the mounting disc 2 3 are respectively located on both sides of the saw blade 2. A circular through hole adapted to the fixing column 4 is provided on the side of the mounting disc 1. By placing the saw blade 2 between the mounting disc 1 and the mounting disc 2 3, the stability is enhanced. At the same time, both sides of the saw blade 2 are protected, which reduces the difficulty of disassembling the saw blade 2. The saw blade 2 is limited between the mounting disc 1 and the mounting disc 2 3 by the plug-in ring 20, and cooperates with the fixing column 4 to prevent the saw blade 2 from shaking when rotating at high speed.

[0024] The fixing grooves 5 are evenly and symmetrically distributed on the outside of the rotating plate 8. The rotating plate 8 is also slidably connected to the inside of the fixing grooves 5. The number of fixing holes 6 and fixing columns 4 is the same. The fixing holes 6 and fixing columns 4 are movably plugged into each other. Fit the saw blade 2 to the side of the mounting plate 2 3, and place the fixing columns 4 inside the fixing holes 6. Then place the mounting plate 1 on the other side of the saw blade 2 and ensure that one end of the fixing column 4 extends to the outside of the mounting plate 1.

[0025] The limit plate 10 is an arc-shaped plate with an inclined surface. The limit plate 10 is slidably connected to the inside of the fixed groove 5. The spring 12 is sleeved inside the slide rail 11. The slider 13 is slidably connected to the inside of the slide rail 11. Under the elastic force of the spring 12, the slider 13 is pushed to rotate the slide rail 11. When the notch 9 is away from the fixed column 4, the rotating plate 8 and the limit plate 10 move to the inside of the fixed groove 5. Since the surface of the limit plate 10 is an inclined surface, as the limit plate 10 moves further, the fixed column 4 will be pushed to move toward the side of the mounting plate 1, thereby making the connection between the mounting plate 1 and the mounting plate 2 3 tighter, avoiding the generation of a gap at the mounting plate 2 3. Subsequently, the elastic force of the spring 12 prevents the rotating plate 8 from rotating and causing the saw blade 2 to loosen from the fixed column 4.

[0026] The guide plate 15 and the guide groove 19 are evenly distributed in a circular array around the center of the mounting plate 2 3. One end of the guide groove 19 is connected to the air hole 18.

[0027] Working principle: When in use, the staff connects and fixes the whole to the drive shaft through the shaft hole 16. When the drive shaft drives the saw blade 2 to rotate and cut, the air flows through the arc-shaped guide plate 15. With the cooperation of the baffle 17, the air enters the guide groove 19 from the air hole 18. The air is discharged after heat exchange inside the guide groove 19. The discharged air will blow to the outer edge of the saw blade 2, thereby discharging the waste chips on the saw blade 2 and in the guide groove 7 in time, enhancing the heat dissipation effect of the saw blade 2. When the teeth of the saw blade 2 are worn after long-term use, the slider 13 is pushed to move in the slide rail 11, and the spring 12 is compressed while driving the rotating plate 8 to rotate until the notch 9 is moved to the outside of the fixed column 4. The mounting plate 1 can be disengaged from the mounting plate 2 3, and the saw blade 2 can be taken out from the outside of the fixed column 4, which is convenient for replacing the saw blade 2. The combined connection method is convenient for replacing the worn teeth themselves without replacing the whole, reducing the cost of use.
