Description

Technical Field

[0001] This utility model relates to the field of cutting saw blade technology, and in particular to an explosion-proof edge saw blade for cutting plates. Background Technology

[0002] When producing wood products, boards need to be cut. When using a saw blade to cut the boards, the saw teeth can easily cause the wood to tear at the edge of the cut point just before penetrating the board, resulting in waste of the board. At the same time, as the saw blade continues to cut the board, the temperature of the saw blade will continue to rise. This continuous increase in temperature will change the metal properties of the saw blade, causing it to age and become damaged.

[0003] Therefore, those skilled in the art have provided an explosion-proof edge saw blade for cutting sheet metal to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an explosion-proof edge saw blade for cutting boards. Through a through groove, the middle and lower ends of the saw teeth are hollowed out, thus forming two grooves on the surface of the board during cutting. The upper part of the saw teeth then cuts through the middle of these grooves, effectively preventing edge chipping at the cut.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An explosion-proof edge saw blade for cutting plates includes a cutting saw blade with multiple saw teeth fixedly connected to its outer wall. Each saw tooth has a through groove on one side of its outer wall, the through groove extending through half of a saw tooth. The upper surface of the cutting saw blade has a first heat dissipation groove and a second heat dissipation groove arranged in an array at intervals in the middle. The upper and lower surfaces of the cutting saw blade are coated with titanium aluminum nitride. The outer wall of the titanium aluminum nitride coating away from the cutting saw blade is coated with a ceramic coating. The ceramic coating away from the titanium aluminum nitride coating is coated with a chromium nitride coating.

[0007] The above technical solution effectively improves the overall heat dissipation performance of the cutting saw blade during high-speed rotation by setting the first and second heat dissipation slots.

[0008] Furthermore, each of the upper surfaces of the cutting saw blade has a mounting groove in the middle.

[0009] The above technical solution makes it easier to install the cutting saw blade onto the cutting machine.

[0010] Furthermore, the thickness of the titanium aluminum nitride coating, the ceramic coating, and the chromium nitride coating is 3 micrometers;

[0011] The above technical solutions indirectly ensure the effectiveness of the cutting saw blade's hardness by providing various coatings with excellent comprehensive performance.

[0012] This utility model has the following beneficial effects:

[0013] 1. The present invention proposes an explosion-proof edge saw blade for cutting plates. Through the provision of a first heat dissipation groove and a second heat dissipation groove, when the cutting saw blade rotates at high speed, the gas inside the first heat dissipation groove and the second heat dissipation groove is continuously thrown out from the outer edge, thereby forming a local low-pressure zone inside the first heat dissipation groove and the second heat dissipation groove. In order to fill this low-pressure zone, high-pressure air from the outside is "drawn" in from the sides and surroundings of the first heat dissipation groove and the second heat dissipation groove, thereby achieving the purpose of heat dissipation for the cutting saw blade.

[0014] 2. The present invention proposes an explosion-proof edge saw blade for cutting boards. Through the through groove, the middle and lower ends of the saw teeth are hollowed out. During cutting, the saw teeth form two grooves on the surface of the board. Then, the upper part of the saw teeth cuts the board in the middle of the two grooves, which can effectively prevent the edge from bursting when cutting the board. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] One specific embodiment of this utility model is provided:

[0023] Reference Figures 1-5 :

[0024] An explosion-proof edge saw blade for cutting plates includes a cutting saw blade 1. Multiple saw teeth 5 are fixedly connected to the outer wall of the cutting saw blade 1. A through groove 6 is opened on one side of the outer wall of each saw tooth 5. The length of the through groove 6 extends through half of the saw tooth 5. A first heat dissipation groove 2 and a second heat dissipation groove 4 are arranged in an array at intervals in the middle of the upper surface of the cutting saw blade 1. A titanium aluminum nitride coating 7 is provided on both the upper and lower surfaces of the cutting saw blade 1. A ceramic coating 8 is provided on the outer wall of the titanium aluminum nitride coating 7 away from the cutting saw blade 1. A chromium nitride coating 9 is provided on the side of the ceramic coating 8 away from the titanium aluminum nitride coating 7.

[0025] The first heat dissipation groove 2 and the second heat dissipation groove 4 can effectively improve the overall heat dissipation performance of the cutting saw blade 1 when rotating at high speed.

[0026] Reference Figure 2 , Figure 3 and Figure 5 :

[0027] The upper surface of the cutting saw blade 1 is provided with a mounting groove 3 in the middle, which makes it easier to install the cutting saw blade 1 onto the cutting machine. The thickness of the titanium aluminum nitride coating 7, ceramic coating 8 and chromium nitride coating 9 is 3 micrometers, which indirectly ensures the effectiveness of the hardness of the cutting saw blade 1 by providing good comprehensive performance of various coatings.

[0028] Working principle: When using, install the cutting saw blade 1 on the cutting machine, and then attach the attached... Figure 2The saw blade rotates counterclockwise. Upon contact with the board, the two tips of the saw teeth 5 first make contact with the board. Then, through high-speed rotation, the two tips cut two grooves in the board. The cutting machine then lowers the depth of the cutting saw blade 1, and the saw teeth 5 cut the board in the middle of the two grooves near the end of the cutting blade 1. By continuously lowering the height of the cutting saw blade 1, the board is cut through the board through the above process. During cutting, the centrifugal force generated by the high-speed rotation causes the gas inside the first heat dissipation groove 2 and the second heat dissipation groove 4 to be thrown out from the outer edge, thus forming a local low-pressure area inside the first heat dissipation groove 2 and the second heat dissipation groove 4. To fill this low-pressure area, high-pressure air from the outside is "drawn" in from the sides and around the first heat dissipation groove 2 and the second heat dissipation groove 4 through the "draw-acceleration-" process. The process of "throwing out" continues in a continuous cycle, forming a "pumping effect" to cool the cutting saw blade. Then, during cutting, the chromium nitride coating 9 effectively reduces the adhesion of wood chips. When the outer chromium nitride coating 9 is worn, the overall wear resistance of the cutting saw blade 1 can be continuously improved by the internal ceramic coating 8 and titanium aluminum nitride coating 7.
