[0019] like Figure 1-Figure 3 As shown, the utility model discloses a saw blade structure for both cutting and grinding, comprising a reinforcing substrate 2, a saw blade 1 and a mounting hole 5. The saw blade 1 is fixed at the outer edge of the reinforcing substrate 2, a plurality of diamond particles are attached and wrapped on the surface of the saw blade 1, a plurality of saw teeth distributed in an array are arranged on the side of the saw blade 1 away from the reinforcing substrate 2, and the mounting hole 5 is penetrated at the center of the reinforcing substrate 2; removable grinding sheets 4 are arranged on both sides of the reinforcing substrate 2, and the grinding sheets 4 are made of diamond abrasive material and can grind the cutting surface of metal or non-metal materials.

[0020] The saw blade 1 , the reinforcing substrate 2 and the grinding sheet 4 are all coaxially arranged with the mounting hole 5 , and the thickness of the reinforcing substrate 2 is twice that of the saw blade 1 .

[0021] In order to improve the silencing and heat dissipation performance of the saw blade 1, a plurality of array-distributed silencing holes 3 are provided at the edge of one side of the reinforcing base plate 2 close to the saw blade 1, and the silencing holes 3 are located between the grinding plate 4 and the saw blade 1; the setting of the silencing holes 3 has the functions of silencing, heat dissipation and reducing resonance.

[0022] In order to fix the grinding sheet 4, an annular connecting sheet is fixedly provided on one side of the grinding sheet 4 close to the mounting hole 5, and the thickness of the connecting sheet is half of the thickness of the grinding sheet 4. The two connecting sheets located on both sides of the reinforcing base sheet 2 are connected by multiple bolt assemblies.

[0023] The two side surfaces of the reinforcing substrate 2 are provided with a plurality of positioning grooves 6 distributed in an array with the center of the mounting hole 5 as the axis. A clamping block 7 cooperating with the positioning groove 6 is fixed on one side of the grinding sheet 4 close to the reinforcing substrate 2 , and the clamping block 7 is inserted into the positioning groove 6 .

[0024] In order to enhance stability, the cross-section of the positioning groove 6 is a convex structure, the small end of the positioning groove 6 extends to the surface of the reinforcing substrate 2, and the large end of the positioning groove 6 is located inside the reinforcing substrate 2, the card block 7 is consistent with the shape and size of the positioning groove 6, and the large end of the card block 7 is clamped at the large end of the positioning groove 6.

[0025] In order to ensure the strength of the reinforcing substrate 2 , the positioning grooves 6 arranged on the two side surfaces of the reinforcing substrate 2 are staggered and cross-arranged.

[0026] In summary, the saw blade 1 structure for both cutting and grinding described in the utility model first aligns the clamping block 7 on the grinding disc 4 with the positioning groove 6 on the reinforcing substrate 2, applies external force to squeeze the clamping block 7, squeezes the clamping block 7 into the positioning groove 6, then flips the reinforcing substrate 2, and clamps another grinding disc 4 onto the reinforcing substrate 2, and finally fixes the two grinding discs to the reinforcing substrate 2 in sequence through the bolt assembly.

[0027] When in use, the reinforcing base plate 2 is connected to the cutting device through the mounting hole 5. The saw blade 1 first cuts the object and then continues to advance. The grinding sheets 4 on both sides grind the cut surface of the object after cutting. After cutting, the cut surface is also grinded at the same time, thereby improving work efficiency.
