Technical Field

[0001] The present invention relates to a saw blade, and more particularly to an anti-deformation saw blade and a processing method thereof. Background Art

[0002] Saw blade is a commonly used sawing tool, which can cut materials by rotating the saw blade. Common saw blades are divided into diamond saw blades and high-speed steel saw blades. Diamond saw blades can cut stone, and high-speed steel saw blades can cut wood, plastic, metal and other materials. Saw blades will generate heat during the sawing process. In order to improve the heat dissipation effect, many saw blades are equipped with heat dissipation grooves. Although the heat dissipation grooves improve the heat dissipation effect of the saw blade, they also affect the structural strength of the saw blade, causing the risk of deformation during the use of the saw blade, which affects the service life of the saw blade. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention provides an anti-deformation saw blade and a processing method. The saw blade has good heat dissipation effect during use, and the saw blade has good structural strength, is not easy to deform during cutting, and has a long service life.

[0005] A plurality of closed anti-deformation heat dissipation grooves are arranged on the saw blade body. During the rotation and cutting process of the saw blade body, the anti-deformation heat dissipation grooves play a role in heat dissipation, and the anti-deformation heat dissipation grooves are arranged in a closed manner, thereby ensuring the structural strength of the saw blade body around the anti-deformation heat dissipation grooves and preventing the saw blade body from being deformed. The anti-deformation heat dissipation grooves are arranged to deviate from the radial direction and the width of the anti-deformation heat dissipation grooves gradually increases in the direction away from the center of the saw blade body. During the rotation of the saw blade body, the tangential force received at the position of the anti-deformation heat dissipation grooves can be decomposed radially, thereby reducing the effect of the tangential force on the saw blade body at the position of the anti-deformation heat dissipation grooves and reducing the risk of deformation of the anti-deformation heat dissipation grooves. A plurality of groups of anti-deformation heat dissipation grooves are evenly distributed circumferentially, so that each position of the saw blade body is subjected to uniform force during the rotation of the saw blade body, thereby ensuring the structural strength of the saw blade body.

[0006] The saw blade of the patent application has good heat dissipation effect during use, and the saw blade has good structural strength, is not easy to deform during cutting, and has a long service life.

The length of the anti-deformation heat dissipation groove 2 and the spacing between two adjacent anti-deformation heat dissipation grooves 2 are reasonably set to ensure the heat dissipation effect while ensuring the structural strength of the saw blade body 1. In this embodiment, L1 is 10mm, L2≥30mm, L3 is 18mm, and L4 is 6mm.

[0058] The cutting blade 9 includes a left bevel blade 13 and a right bevel blade 14. The outer end surface 18 of the left bevel blade 13 is inclined from right to left toward the center of the saw blade body 1, and the outer end surface 18 of the right bevel blade 14 is inclined from left to right toward the center of the saw blade body 1. The widths of the left bevel blade 13 and the right bevel blade 14 are both greater than the thickness of the saw blade body 1. The left and right sides of the left bevel blade 13 extend out of the left and right sides of the saw blade body 1, respectively, and the left and right sides of the right bevel blade 14 extend out of the left and right sides of the saw blade body 1, respectively.

[0059] The left bevel blade 13 and the right bevel blade 14 are arranged alternately along the circumferential direction. The left side 16, the right side 17, the outer end face 18, and the front side 19 of the cutting blade 9 are all planes. The plane structure facilitates the grinding and trimming of the cutting blade 9. The front side 19 of the cutting blade 9 is provided with a corner surface 15 near the center side of the saw blade body 1, and the corner surface 15 is inclined away from the saw blade body 1 in the direction of rotation and cutting. The setting of the corner surface 15 is conducive to the discharge of chips.

[0060] The left side 16 and the right side 17 of the cutting head 9 are both inclined away from the rotation cutting direction of the saw blade body 1 and toward each other. The left side 16 and the right side 17 of the cutting head 9 are inclined, which reduces the contact area between the left side 16 and the right side 17 of the cutting head 9 and the sawing section, which is beneficial to reducing the sawing resistance. A space is formed between the rear side of the left side 16 and the right side 17 and the sawing surface, which is beneficial to heat dissipation and chip discharge.

[0061] A plurality of closed anti-deformation heat dissipation grooves 2 are arranged on the saw blade body 1. During the rotation and cutting process of the saw blade body 1, the anti-deformation heat dissipation grooves 2 play a role in heat dissipation. Moreover, the anti-deformation heat dissipation grooves 2 are arranged in a closed manner, thereby ensuring the structural strength of the saw blade body 1 around the anti-deformation heat dissipation grooves 2 and preventing the saw blade body 1 from being deformed. The anti-deformation heat dissipation grooves 2 are arranged to deviate from the radial direction and the width of the anti-deformation heat dissipation grooves 2 gradually increases in the direction away from the center of the saw blade body 1. During the rotation of the saw blade body 1, the tangential force received at the position of the anti-deformation heat dissipation grooves 2 can be decomposed radially, thereby reducing the effect of the tangential force on the saw blade body 1 at the position of the anti-deformation heat dissipation grooves 2 and reducing the risk of deformation of the anti-deformation heat dissipation grooves 2. A plurality of groups of anti-deformation heat dissipation grooves 2 are evenly distributed circumferentially, so that each position of the saw blade body 1 is subjected to uniform force during the rotation of the saw blade body 1, thereby ensuring the structural strength of the saw blade body 1.

[0062] A method for processing an anti-deformation saw blade, which realizes the processing of the anti-deformation saw blade, and includes the following steps: S1, processing an anti-deformation heat dissipation groove 2 on a saw blade body 1, and the anti-deformation heat dissipation groove 2 is processed by stamping, first stamping out a rough outline, and then trimming the outline to form a complete anti-deformation heat dissipation groove 2; S2, processing a plurality of circumferentially spaced accommodation grooves on the edge of the saw blade body 1, and forming a tooth back 8 between two adjacent accommodation grooves; S3, heat treating the saw blade body 1, first quenching and then tempering during the heat treatment process; S4, processing a tooth seat 11 on the tooth back 8; S5, welding a cutting head 9 on the tooth seat 11, and the cutting head 9 includes a left bevel head 13 and a right bevel head 14, and the left bevel head 13 and the right bevel head 14 are alternately arranged along the circumference.

[0063] When the saw blade is processed, the anti-deformation heat dissipation groove 2 and the chip groove 10 are processed on the saw blade body 1, and the hardness of the saw blade body 1 is increased after heat treatment, and then the cutting head 9 is welded to the tooth seat 11 to form a saw blade. The saw blade is easy to process, and the processed saw blade has good heat dissipation effect, good structural strength, is not easy to deform during the cutting process, and has a long service life.
