Technical Field

[0001] The utility model belongs to the field of saw blades, and particularly relates to a highly wear-resistant and environment-friendly saw blade. Background Technique

[0002] A saw blade is a tool used for various cutting tasks and is widely applied in multiple industries and application fields such as woodworking, metal processing, stone processing, plastic processing, etc. During processing, a suitable type of saw blade is selected according to the material to be cut to ensure that the saw blade can effectively and safely complete the work. According to the requirements of a specific sawing machine or tool, the saw blade is installed and ensured to be firmly installed to avoid unnecessary vibrations or dangers during operation.

[0003] In the work of existing saw blades, the side surface of the saw blade is in direct contact with the cutting material, and is subject to large friction and easy to wear, thus affecting the service life of the saw blade. And based on the friction between the side surface of the saw blade and the cutting material, a large amount of noise is usually generated. Summary of the Utility Model

Detailed Embodiments

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0021] As Figures 1 to 3 shown, a highly wear-resistant and environment-friendly saw blade provided by an embodiment of the present utility model includes a saw blade body 1, includes a mounting hole 11 integrally formed with the saw blade body 1, and further includes:

[0022] Cutting unit 2, multiple groups of the cutting unit 2 are arranged in a ring along the outer edge of the saw blade body 1. The cutting unit 2 includes a cutting edge 3 for cutting. A chip groove 4 is fixedly arranged on one side of the cutting edge 3. An alloy cutter head 5 is also welded inside the cutting edge 3. A cutter head groove 31 is arranged at the position corresponding to the alloy cutter head 5 on the cutting edge 3.

[0023] Sound-absorbing unit 6, multiple groups of the sound-absorbing unit 6 are arranged in a ring along the outer edge of the saw blade body 1. The sound-absorbing unit 6 includes a sound-absorbing groove 7 with one end communicating with the chip groove 4. The other end of the sound-absorbing groove 7 communicates with a sound-absorbing hole 8. An auxiliary sound-absorbing groove 9 is fixedly arranged on one side of the sound-absorbing hole 8.

[0024] In an embodiment of the present invention, the cutting of materials by the high-hardness wear-resistant alloy cutter head 5 welded in the cutter head groove 31 improves the wear resistance of the saw blade and increases the service life of the saw blade. By arranging heat dissipation grooves 12 in the middle of both sides of the saw blade body 1, the contact area between the side of the saw blade and the cutting material is reduced, friction is reduced, and the heat dissipation space is increased, reducing noise and rotational resistance. And through this design, the weight of the saw blade is reduced, further reducing the motor load. By arranging the sound-absorbing unit 6, the noise of the cutting unit 2 part is reduced, improving the use comfort.

[0025] As Figure 3 shown, as a preferred embodiment of the present invention, heat dissipation grooves 12 are fixedly arranged in the middle of both sides of the saw blade body 1.

[0026] Furthermore, the alloy cutter head 5 is made of a high-hardness wear-resistant material, and the thickness of the alloy cutter head 5 is greater than that of the cutting edge 3.

[0027] In an example of the present invention, by arranging heat dissipation grooves 12 in the middle of both sides of the saw blade body 1, the contact area between the side of the saw blade and the cutting material is reduced, friction is reduced, and the heat dissipation space is increased, reducing noise and rotational resistance. And through this design, the weight of the saw blade is reduced, further reducing the motor load. By arranging the alloy cutter head 5, the wear resistance of the saw blade is improved, and the service life of the saw blade is increased. And the welding design reduces the material cost of the saw blade while meeting the wear resistance requirements. By setting the thickness of the alloy cutter head 5 to be greater than that of the cutting edge 3, during cutting, the direct friction of the material on the surface of the cutting edge 3 can be reduced, increasing the service life of the saw blade.

[0028] As a preferred embodiment of the present invention, the cutting edge 3 is treated by quenching and carburizing to improve hardness and wear resistance.

[0029] In an example of the present utility model, during the saw blade cutting operation, the cutting edge 3 will inevitably collide and rub against the material and chips. Through quenching and carburizing treatments, the hardness and wear resistance of the cutting edge 3 can be improved, thereby increasing the service life of the saw blade.

[0030] As Figures 1 to 2 shown, as a preferred embodiment of the present utility model, the sound-absorbing groove 7 is provided as a strip-shaped groove with a rectangular cross-section. The sound-absorbing hole 8 is provided as a circular through-hole. The auxiliary sound-absorbing groove 9 is provided as an "S"-shaped groove.

[0031] In an example of the present utility model, by arranging the sound-absorbing groove 7 in cooperation with the sound-absorbing hole 8 and the auxiliary sound-absorbing groove 9, the structure and shape of the saw blade can be changed, vibrations generated during cutting can be reduced, and thus the generation of noise can be reduced. When the saw blade encounters the material during operation, the sound-absorbing unit 6 will change the way of air flow, reducing the sound generated by gas flow. In addition, the sound-absorbing unit 6 can increase the heat dissipation area on the surface of the saw blade, helping to quickly dissipate the heat, reducing the heat generated by friction during the operation of the saw blade, and reducing the risk of deformation of the saw blade.
