As shown in fig. 1 and 2, a power saw blade having a three-dimensional surface structure, which is mainly an electric or the like power saw blade (different from a manual saw), such as a reciprocating saw blade, a curved saw blade, a band saw blade, a circular saw blade, and the like; the saw blade for the power saw comprises a back material 1, wherein saw teeth 2 are arranged on the back material 1, and a three-dimensional surface structure 3 used for adjusting the overall balance degree of the back material is arranged on the surface of the back material 1, so that the deflection and vibration caused by self unbalance are reduced when the saw blade for the power saw is used.

Wherein, the whole shape of the saw blade with the three-dimensional surface structure is sheet-shaped, because only the sheet-shaped (thinner) saw blade can generate deflection and vibration in the actual use, and at the same time, the saw blade also needs to be an electric saw blade with power, and the like, because the manual saw is driven by manpower to reciprocate in the use process, the reciprocating speed is not high, the amplitude of the deflection and vibration is not large, and even if the deflection and vibration occur, the saw blade can be adjusted by hands, therefore, the technical proposal mainly arranges the three-dimensional surface structure 3 on the surface of the electric saw blade with power, and the thickness of the back material 1 is not needed to be increased, on one hand, the saw path of the saw blade can be ensured to be narrower, the resistance in the processing application can be reduced, the efficiency performance can be improved, on the other hand, the problem of the deflection and vibration in the actual use caused by the thinner thickness of the sheet-shaped saw blade can be solved, the saw blade has better rigidity and smaller processing resistance.

In some embodiments, the three-dimensional surface structure 3 may be implemented by providing different structures as required, such as providing through holes on the surface of the back material 1; or a blind hole is arranged on the surface of the backing material 1 (the blind hole is a via hole which connects the surface layer and the inner layer but does not penetrate the whole plate); or welding salient points on the surface of the back material 1; or a pressing hole is formed on the surface of the back material 1, one surface of the back material 1 is pressed to the other surface but is not penetrated at the pressing hole, and a structure with one surface being concave and the other surface being convex is formed; and so on. The three-dimensional surface structure 3 can be realized by adopting any one of the structures according to actual needs, can also be realized by combining any two structures, or simultaneously adopts a plurality of structural combinations, so that the use requirements are met.

Wherein, the purpose of setting up three-dimensional surface structure 3 is in order to make the atress ability of whole saw bit when using of saw bit for the power saw more balanced: the three-dimensional surface structure 3 is designed to be a through hole arranged on the surface of the back material 1 or a blind hole arranged on the surface of the back material 1, and is mainly characterized in that the weights of different positions of the saw blade are possibly different due to various reasons (such as processing errors, requirements of sawing materials and the like) on the whole saw blade, so that the deflection and vibration of the saw blade during working can be aggravated, and the weight of the position can be reduced by arranging the through hole or the blind hole on the position with heavier weight on the surface of the saw blade, so that the stress of the whole saw blade can be more balanced; the three-dimensional surface structure 3 is designed to weld salient points on the surface of the back material 1, and the two surfaces of the back material 1 are stressed more evenly in a weight increasing mode on the surface of the back material 1; the three-dimensional surface structure 3 is designed to apply a compression hole on the surface of the back material 1, wherein one surface of the back material 1 presses against the other surface but is not penetrated through the compression hole to form a structure with one surface being concave and the other surface being convex, so that the three-dimensional surface structure is suitable for realizing the effect of reducing weight on one surface and increasing weight on the other surface by forming the structure with one surface being concave and the other surface being convex when the two surfaces of the back material 1 are unbalanced in stress, and the two surfaces of the back material 1 are more balanced in stress.

As a preferred embodiment, the three-dimensional surface structure 3 is designed to weld protruding points on the surface of the back material 1, because of this structure, there is no need to process the structure of the back material 1 itself (i.e. the back material 1 can still maintain its shape and size), which can ensure the rigidity performance during saw blade processing, and only the protruding points need to be welded on the surface of the back material 1 to solve the above problems.

The saw blade for a power saw having a three-dimensional surface structure described above will be described with reference to a saber saw (one of reciprocating saws is used for sawing pipes, profiles, and wood):

the saber saw comprises a back material 1, sawteeth 2 are arranged on the back material 1, and a three-dimensional surface structure 3 for adjusting the integral balance degree of the back material is arranged on the surface of the back material 1, so that the deflection and vibration caused by the unbalance of the saw blade for the power saw are reduced when the saw blade is used; the three-dimensional surface structure 3 is designed to apply a squeezing hole on the surface of the back material 1, wherein one surface of the back material 1 presses against the other surface but is not penetrated at the squeezing hole to form a structure with one surface being concave and the other surface being convex.

In some embodiments, the backing 1 comprises a front side, a rear side, an upper side, a lower side, a left surface and a right surface, which together form a complete saw blade, the teeth 2 are arranged on the lower side, and the relief surface structure 3 is arranged on the left surface and/or the right surface.

In some embodiments, the front side is inclined to form a narrow front and a wide back shape for the entire saw blade, which makes it easier and less resistant to sawing material.

In some embodiments, the upper side is provided in a stepped shape with a lower front and a higher rear to reduce resistance when sawing the material.

In some embodiments, an end of the upper side surface close to the rear side surface is provided with a step shape with a high front and a low rear to meet the installation requirement.

In some embodiments, a mounting through hole 11 is provided at a position of the backing material 1 near the rear side surface for use in mounting with other structures of a power saw.

In some embodiments, an outwardly projecting mounting portion 12 is provided on the rear side to meet mounting requirements.
