Description

Technical Field

[0001] This utility model relates to the field of cutting saw blade technology, and in particular to a composite noise-reducing carbide saw blade structure. Background Technology

[0002] Carbide saw blades are the most commonly used cutting tools. The quality of carbide saw blades is closely related to the quality of processed products. Correctly and reasonably selecting carbide saw blades is of great significance for improving product quality, shortening processing cycles, and reducing processing costs. Carbide saw blades include multiple parameters such as the type of carbide tip, the material of the base body, diameter, number of teeth, thickness, tooth shape, angle, and bore diameter. These parameters determine the saw blade's processing capacity and cutting performance. When selecting a saw blade, it is necessary to choose the correct blade based on the type and thickness of the material being sawed, the sawing speed, the sawing direction, the feed speed, and the kerf width.

[0003] Chinese Patent Publication No. CN218593206U discloses a composite noise-reducing carbide circular saw blade. Through the design of multiple heat dissipation holes, it increases the contact area between the saw blade body and the outside air, preventing the saw blade body from breaking due to overheating during operation. Simultaneously, the multiple finger holes on the handle enhance airflow speed through pressure changes, thereby more effectively dissipating heat from the circular saw blade body. These finger holes also facilitate user handling and carrying of the circular saw blade body, improving user convenience. The overall structure is simple to operate and easy to use, improving heat dissipation performance while also facilitating user handling and carrying. The blade is connected via a threaded connection between a fastening bolt and a fastening groove.

[0004] The mounting plate facilitates the installation of the fixing plate onto the circular saw blade body, ensuring the stability of the handle and enhancing the connection strength between the handle and the circular saw blade body. It also facilitates the subsequent disassembly and assembly of the handle, thereby improving the convenience of the user when disassembling and assembling the handle. By using the sound-absorbing slot, the first sound-absorbing hole and the second sound-absorbing hole, the noise during cutting can be reduced. At the same time, the first sound-absorbing hole and the second sound-absorbing hole can eliminate stress concentration when processing the sound-absorbing slot, preventing cracks from forming in the circular saw blade body.

[0005] The aforementioned carbide saw blades are integral structures, requiring complete replacement when wear occurs. This results in high application costs for carbide saw blades. Furthermore, the integral structure of the carbide saw blade provides a good vibration transmission path, leading to high noise during cutting. Therefore, this utility model discloses a composite noise-reducing carbide saw blade structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a composite noise-reducing carbide saw blade structure, which solves the technical problem that traditional carbide saw blades are integral structures, requiring the entire blade to be replaced when wear occurs, resulting in high application costs. Furthermore, the integral structure of the carbide saw blade provides a good vibration transmission path, leading to high noise during cutting.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A composite noise-reducing carbide saw blade structure includes two side guards and multiple spliced ​​saw blades located between the two side guards;

[0009] The splicing saw blades are all fan-shaped, and multiple splicing saw blades together form a ring. The two side guard plates are fixed together by screws to form an integral structure, so that multiple splicing saw blades are clamped and positioned between the two side guard plates.

[0010] Beneficial effects: This composite sound-absorbing carbide saw blade structure holds multiple fan-shaped spliced ​​saw blades between two side guards. When a single saw blade is worn or damaged, the spliced ​​saw blade can be replaced individually, reducing maintenance costs. The spliced ​​saw blades with multiple fan-shaped structures, together with the connecting holes, can limit the overall vibration of the saw blade and reduce the propagation path of sound waves, thus achieving a noise reduction effect. In addition, the connecting holes, together with the heat dissipation holes, help the saw blade dissipate heat during use, prevent the saw blade from overheating, and extend the service life of the saw blade.

[0011] Furthermore, the outer arc of the splicing saw blade is fixed with an arc-shaped strip, and multiple cutting teeth are equidistantly arranged on the side of the arc-shaped strip away from the splicing saw blade.

[0012] Furthermore, a spline groove is provided in the middle of each of the two side guard plates, and a central ring is fixed to the edge of the spline groove on the adjacent side of the two side guard plates. The central ring is provided with multiple assembly holes.

[0013] Furthermore, multiple heat dissipation holes are provided at the center of the outer arc of the side guard plate, and corresponding connection holes are provided on the splicing saw blade corresponding to the heat dissipation holes.

[0014] Furthermore, the side guard plate is provided with multiple connecting posts on the side facing the splicing saw blade, and the splicing saw blade is provided with corresponding through holes for each connecting post.

[0021] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0022] See Figures 1 to 4 As shown, a composite noise-reducing carbide saw blade structure includes two side guards 1 and multiple spliced ​​saw blades 2 located between the two side guards 1.

[0023] Specifically, the main material of the splicing saw blade 2 is composed of tungsten and cobalt. Tungsten provides excellent hardness and wear resistance, while cobalt acts as a binder to enhance the toughness and impact resistance of the saw blade. The side guard plate 1 is made of carbon steel or alloy steel, which can provide stable lateral support.

[0024] The splicing saw blades 2 are all fan-shaped, and multiple splicing saw blades 2 together form a ring. The two side guard plates 1 are fixed together with screws to form an integral structure, so that multiple splicing saw blades 2 are clamped and positioned between the two side guard plates 1.

[0025] Specifically, the side guard plate 1 is fixed as an integral structure with screws, providing stable support for the splicing saw blade 2, ensuring the stability and accuracy of the saw blade when rotating at high speed. The clamping force of the side clamps can also prevent the splicing saw blade 2 from shaking when under force. When a splicing saw blade 2 is worn or damaged, it can be replaced individually without replacing the entire saw blade, which greatly reduces maintenance costs. In addition, the design of multiple splicing saw blades 2 helps to reduce vibration, thereby reducing the noise generated during the cutting process.

[0026] Furthermore, an arc-shaped strip 21 is fixed to the outer arc of the splicing saw blade 2, and multiple cutting teeth 22 are equidistantly arranged on the side of the arc-shaped strip 21 away from the splicing saw blade 2;

[0027] Specifically, the equidistant distribution of the cutting teeth 22 on the arc-shaped strip 21 ensures a uniform cutting force during the cutting process, thereby improving cutting efficiency and cutting quality. The arc-shaped strip 21 serves as a support structure for the cutting teeth 22, which can transfer stress to the side guard plate 1 and the splicing saw blade 2, helping to protect the cutting teeth 22, extend the service life of the cutting teeth 22, and reduce the wear of the cutting teeth 22 under high load operation.

[0028] Furthermore, a spline groove 11 is provided in the middle of each of the two side guard plates 1, and a central ring 12 is fixed on the edge of the spline groove 11 on the adjacent side of the two side guard plates 1. The central ring 12 is provided with a plurality of mounting holes 13.

[0029] Specifically, the spline groove 11 is used to transmit torque, the center ring 12 provides a stable center point for the saw blade, which helps to maintain the balance and stability of the saw blade when rotating at high speed, and the fixing effect of the center ring 12 enhances the rigidity of the side guard plate 1, which helps to reduce the deformation of the side guard plate 1 during the cutting process. The mounting hole 13 facilitates the screw fixing of the two center rings 12 into a single structure.

[0030] Furthermore, multiple heat dissipation holes 14 are provided at the center of the outer arc of the side guard plate 1, and corresponding connection holes 23 are provided on the splicing saw blade 2 corresponding to the heat dissipation holes 14.

[0031] Specifically, the heat dissipation hole 14 and the connection hole 23 increase the contact area between the saw blade and the outside air, which helps to dissipate heat during use and prevent the saw blade from overheating due to long-term high-speed operation, thereby avoiding material fatigue and performance degradation. In addition, the connection hole 23 also makes it convenient to hold when installing or replacing splicing saw blade 2.

[0032] Furthermore, the side guard plate 1 is provided with a plurality of connecting posts 15 on the side facing the splicing saw blade 2, and the splicing saw blade 2 is provided with corresponding through holes 24 on the connecting posts 15.

[0033] Specifically, the through hole 24 allows the connecting post 15 to be inserted, so that the splicing saw blade 2 is fixed in the appropriate position. The function of the connecting post 15 is to provide a fixing point for the splicing saw blade 2, ensuring the stability and accuracy of the carbide saw blade during the cutting process, so as to enhance the structural strength of the carbide saw blade.

[0034] Furthermore, chip removal grooves 25 are provided at both ends of the outer arc of the splicing saw blade 2;

[0035] Specifically, the chip removal grooves 25 of adjacent spliced ​​saw blades 2 are spliced ​​together, so that chips can be smoothly discharged from the chip removal grooves 25 of the carbide saw blade, reducing the damage to the saw blade caused by chip accumulation, thereby improving cutting efficiency and the service life of the carbide saw blade.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
