Therefore, when the saw blade rotates at high speed and contacts the workpiece for cutting, these forces will cause stress concentration in certain areas of the saw blade. If the stress cannot be effectively dispersed in these areas, it will cause excessive local stress, thereby causing damage to the saw blade. Utility Model Content

If the stress cannot be effectively dispersed in these areas, it will cause excessive local stress, thereby causing damage to the saw blade. A saw blade with increased surface stress is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a saw blade with increased surface stress, comprising a saw blade body, a plurality of tooth grooves are evenly arranged at the edge of the outer surface of the saw blade body, buffer grooves are arranged on the outer surfaces of both sides of the saw blade body near the tooth grooves, a plurality of first annular hammer points are evenly arranged on the top of the saw blade body, a plurality of groups of first linear hammer points are arranged near the outer side of the first annular hammer points on the top of the saw blade body, a plurality of second annular hammer points are evenly arranged on the bottom of the saw blade body, and a plurality of groups of second linear hammer points are arranged near the outer side of the second annular hammer points on the bottom of the saw blade body.
[0006] Preferably, a center hole is opened at the center of the outer surface of the saw blade body, and a plurality of mounting holes are evenly opened on the outer surface of the saw blade body near the outer side of the center hole.
[0007] Preferably, the positions of the first annular hammer point and the second annular hammer point (8) are matched, and the positions of the first linear hammer point and the second linear hammer point are staggered.

[0010] Preferably, the buffer groove extends from the edge of the saw blade body to a plane position, and the depth of the buffer groove is 0.1-0.2 mm.
[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
[0012] 1. In the utility model, when the saw blade body rotates at high speed and contacts the workpiece for cutting, the first annular hammer point can form an annular compressive stress zone on the surface of the saw blade body, which is helpful to evenly distribute stress and reduce local stress concentration. The first linear hammer point can further expand the influence range of the compressive stress of the first annular hammer point, so that the stress distribution on the surface of the entire saw blade body is more uniform. At the same time, the second annular hammer point and the second linear hammer point on the other side of the saw blade body are arranged in coordination.

When the saw blade body 1 rotates at high speed and contacts the workpiece for cutting, through the coordinated setting of the first annular hammer point 6 and the first linear hammer point 7 on the surface of the saw blade body 1, the first annular hammer point 6 can form an annular compressive stress belt on the surface of the saw blade body 1, which helps to evenly distribute stress and reduce local stress concentration. The first linear hammer point 7 can further expand the influence range of the compressive stress of the first annular hammer point 6, so that the stress distribution on the surface of the entire saw blade body 1 is more uniform.

The first linear hammer point 7 can further expand the influence range of the compressive stress of the first annular hammer point 6, making the stress distribution on the surface of the entire saw blade body 1 more uniform. Uniform, and at the same time, with the coordinated setting of the second annular hammer point 8 and the second linear hammer point 9 on the other side of the saw blade body 1, the second annular hammer point 8 in the relative position and the second linear hammer point 9 in the staggered position are helpful to balance the structural stress of the saw blade, reduce the deformation caused by unilateral stress concentration, and further improve the structural stability of the saw blade body 1. By setting the buffer groove 5 between the tooth grooves 4, when the saw blade body 1 is subjected to force to cut the workpiece, the position of the buffer groove 5 plays a role in increasing the surface area of the cutting position of the saw blade body 1, which helps to quickly dissipate heat, thereby keeping the saw blade body 1 within the optimal operating temperature range and improving the cutting strength of the saw blade body 1.
