[0002] Diamond saw blade is a cutting tool widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, ceramics, etc. It is mainly composed of two parts: the matrix and the diamond bit. Diamond, as the hardest substance, rubs in the bit to cut the object being processed.
[0003] When a diamond saw blade is in use, the main part that contacts the material being cut is the diamond cutter head. Since the cutter head is usually welded to the saw blade body, the long-term stress on the cutter head during the cutting process may cause tiny cracks in the welding area with the saw blade, resulting in breakage at the connection between the saw blade and the cutter head. Utility Model Content

[0008] The effect achieved by the above components is that the grooves on the surface of the metal sheet can accelerate the air circulation around the metal sheet and the cutter head when the saw blade is used for cutting, thereby dissipating the heat at the cutter head.
[0009] Preferably, a plurality of reinforcing rods are fixedly connected to one side of the metal sheet, and two ends of the reinforcing rods are respectively fixedly connected to one side of the two metal sheets close to each other.
[0010] The effect achieved by the above components is that the metal sheets can be connected by arranging the reinforcing rods, thereby further increasing the structural stability of the metal sheets on the outer surface of the disk body.
[0011] Preferably, a convex ring is fixedly connected to one side of the metal ring, and the height of the middle end of the outer surface of the convex ring is higher than the height at the edge.
[0012] The effect achieved by the above components is that by providing the convex ring, the waste cut by the saw blade can easily slide off the surface of the convex ring and is not easy to stay on the outer surface of the connection between the metal ring and the metal ring and the metal sheet.
[0013] Preferably, a plurality of inclined grooves are provided on the outer surface of the disc body near the chip groove, and the height of the inner wall of the inclined groove near one end of the chip groove is lower than the height of the inner wall of the inclined groove away from the chip groove.

A groove is provided on the outer surface of the rubber ring, and the inner width of the groove is matched with the width of the outer surface of the cutter head.
[0016] The effect achieved by the above components is: when the saw blade is not in use or is being transported, the rubber ring can be pulled to deform the rubber ring, and the groove inside the rubber ring can be put on the outside of the cutter head at the edge of the disk body in sequence. The cutter head is covered by the rubber ring to prevent the cutter head from being worn by accidental impact as much as possible.
[0017] Preferably, an annular strip is fixedly connected to the outer surface of the rubber ring, and the annular strip is located at upper and lower sides of the outer surface of the rubber ring, and the annular strip is a rubber strip with a certain hardness.
[0018] The effect achieved by the above components is that the edge of the rubber ring can be reinforced by arranging the annular strip to avoid the edge of the rubber ring from being worn and broken as much as possible.
[0019] Preferably, a convex piece is fixedly connected to the outer surface of the rubber ring, and one end of the convex piece protrudes from the outer surface of the rubber ring.
[0020] The effect achieved by the above components is that after the rubber ring is sleeved on the outer surface of the saw blade, the rubber ring can be conveniently pulled by pinching the protruding piece to deform the rubber ring and remove the rubber ring from the surface of the saw blade.

[0030] Reference Figure 1-4 As shown, in the present embodiment: a plurality of grooves 24 are provided on the outer surface of the metal sheet 21, and the grooves 24 are linearly distributed on the outer surface of the metal sheet 21. When the saw blade is used for cutting, the grooves 24 on the surface of the metal sheet 21 can accelerate the air circulation near the metal sheet 21 and the cutter head 4, and dissipate heat at the cutter head 4. A plurality of reinforcing rods 25 are fixedly connected to one side of the metal sheet 21, and the two ends of the reinforcing rods 25 are respectively fixedly connected to the sides of the two metal sheets 21 close to each other. By setting the reinforcing rods 25, the metal sheets 21 can be connected to each other, thereby further increasing the structural stability of the metal sheet 21 on the outer surface of the disk body 1.
[0031] Reference Figure 1-4 As shown, in the present embodiment: a convex ring 23 is fixedly connected to one side of the metal ring 22, and the middle end height of the outer surface of the convex ring 23 is higher than the height at the edge.
