As shown in Figures 1 and 2, a saw blade for a power saw with a three-dimensional surface structure is mainly an electric power saw blade (different from a manual saw), such as a reciprocating saw blade, a jig saw blade, a band saw blade, a circular saw Sheets, etc.; including a backing material 1, on which serrations 2 are arranged, and a three-dimensional surface structure 3 for adjusting the overall balance of the backing material is arranged on the surface of the backing material 1, so that all The saw blade for a power saw reduces the yaw and vibration caused by its own unbalance during use.

Among them, the overall shape of the power saw blade with a three-dimensional surface structure is a sheet shape, because only a sheet-shaped (thin thickness) saw blade is likely to have deflection and vibration during actual use, and at the same time It also needs to be an electric and other powered saw blade, because in the process of using the manual saw, it is manually driven to reciprocate. The pendulum and vibration can also be adjusted by hand, so the technical solution is mainly to set the three-dimensional surface structure 3 on the surface of the electric saw blade with power, so that the thickness of the backing material 1 does not need to be increased, on the one hand, the sawing path of the saw blade can be guaranteed. It is narrower to reduce the resistance during processing and application and improve the efficiency performance. At the same time, it has better rigidity and less processing resistance.

In some specific embodiments, the three-dimensional surface structure 3 can be implemented by setting different structures as required, such as setting through holes on the surface of the backing material 1; or setting blind holes (blind holes) on the surface of the backing material 1 The hole is a through hole that connects the surface layer and the inner layer without penetrating the whole board); or solder bumps on the surface of the backing material 1; or press an extrusion hole on the surface of the backing material 1, where One surface of the backing material 1 is pressed against the other surface but does not penetrate through, forming a structure in which one surface is concave and the other surface is convex; and so on. Wherein, the three-dimensional surface structure 3 can be realized by any of the above-mentioned structures according to actual needs, or can be realized by a combination of any two structures, or a combination of multiple structures can be realized at the same time, so as to meet the usage requirements.

Wherein, the purpose of setting the three-dimensional surface structure 3 is to make the force of the entire saw blade more balanced when the power saw blade is in use: and the three-dimensional surface structure 3 is designed to be arranged on the surface of the backing material 1 Through holes or blind holes are provided on the surface of the backing material 1, which is mainly because the different positions of the saw blade are caused by various reasons (such as processing errors, sawing material requirements, etc.) on the entire saw blade. The weight may be different, which will aggravate the yaw and vibration of the saw blade during operation. By setting a through hole or a blind hole at a position where the surface of the saw blade is heavier, the weight of the position can be reduced, so that the entire saw blade is The force can be more balanced; and the three-dimensional surface structure 3 is designed to weld bumps on the surface of the backing material 1, and by adding weight on the surface of the backing material 1, the two surfaces of the backing material 1 are The three-dimensional surface structure 3 is designed to press an extrusion hole on the surface of the backing material 1, where one surface of the backing material 1 is pressed to the other surface but does not penetrate through the extrusion hole. , forming a structure in which one surface is concave and the other surface is convex is suitable for when the force between the two surfaces of the backing material 1 is unbalanced, by forming a structure in which one surface is concave and the other surface is convex , so as to achieve the effect of weight reduction on one surface and weight gain on the other surface, so as to make the force between the two surfaces of the backing material 1 more balanced.

As a preferred embodiment, the three-dimensional surface structure 3 is designed to weld bumps on the surface of the backing material 1, because of this structure, the structure of the backing material 1 itself does not need to be processed (ie the The backing material 1 can still maintain its own shape and size), which can ensure the rigidity of the saw blade during processing. It only needs to weld bumps on the surface of the backing material 1 to solve the above problems. The processing technology of welding bumps is compared with other The processing technology of the structure is simpler (because the thickness of the saw blade is thin, the processing strength is not easy to control when processing through holes, blind holes, and a concave and convex structure on the surface of the backing material 1, and it needs to be repeatedly adjusted. It is easy to damage the saw blade and even cause scrap), the operation is more convenient, and it is beneficial to reduce the processing cost and processing efficiency.
