Description

Technical Field

[0001] This utility model relates to the field of saw blade technology, and in particular to a saw blade that reduces noise. Background Technology

[0002] Saw blades, as a general term for thin, circular cutting tools for cutting solid materials, can be divided into three main categories based on the object being cut: first, diamond saw blades, specifically designed for stone cutting; second, high-speed steel saw blades (without carbide tips), mainly used for cutting metal materials; and third, carbide saw blades, suitable for cutting various materials such as solid wood, furniture, engineered wood, aluminum alloys, aluminum profiles, radiators, plastics, and PVC.

[0003] However, during high-speed rotation and cutting, the saw blade generates significant noise due to friction with the material and its own vibration. Resonance is a key factor contributing to this significant noise amplification. The saw blade itself is a thin metal sheet structure, and during high-speed rotation, uneven forces cause periodic vibrations. When the frequency of this vibration matches the saw blade's natural frequency, resonance occurs, leading to a sharp increase in noise and severely impacting the saw blade's performance. Utility Model Content

[0004] The main technical problem solved by this invention is to provide a saw blade that reduces noise, thus solving the problem of excessive noise.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a noise-reducing saw blade is provided, comprising: an annular saw blade body and a fixing ring connected to its inner hole, wherein a plurality of cutting tooth assemblies are connected in an annular array on the outer circular surface of the annular saw blade body, and a volume groove is provided between adjacent cutting tooth assemblies, wherein a noise-reducing tooth assembly is provided in the volume groove respectively.

[0006] It also includes several U-shaped noise-absorbing grooves arranged in a ring array on the fixed ring, and L-shaped noise-absorbing grooves are provided between adjacent U-shaped noise-absorbing grooves. One end of the L-shaped noise-absorbing groove extends to the ring saw blade body and communicates with the corresponding volume groove, and the other end extends to the fixed ring.

[0007] By adopting the above technical solution, the saw blade's retaining ring is installed on the rotating shaft of the cutting equipment. The rotating shaft drives the saw blade to rotate at high speed, at which point several cutting tooth assemblies on the outer circumference of the annular saw blade body cut the material. However, during the cutting process, significant friction occurs between the cutting tooth assemblies and the material, and coupled with the saw blade's own vibration, this generates considerable noise. This saw blade, by incorporating sound-absorbing tooth assemblies within the volumetric groove, effectively disrupts and disperses the sound waves generated by vibration, reducing resonance and thus lowering noise levels. Simultaneously, the use of U-shaped sound-absorbing grooves breaks the overall rigid structure of the retaining ring, dispersing its natural frequency and preventing resonance; the application of L-shaped sound-absorbing grooves breaks the overall rigid structure of both the retaining ring and the annular saw blade body, dispersing their fixed frequencies and similarly preventing resonance. Through these designs, noise amplification is reduced at its source, significantly enhancing the saw blade's performance.

[0008] In a preferred embodiment, the present invention can be further configured such that: the cutting tooth assembly includes a fixed tooth, the outer end of the fixed tooth is provided with a fixed groove, and the cutting tooth body is connected in the fixed groove.

[0009] By adopting the above technical solution, the cutting tooth body is connected to the ring saw blade body through fixed teeth: the fixed teeth are connected to the ring saw blade body, and the cutting tooth body is fixed in the fixed groove of the fixed teeth. This structure allows the cutting tooth body and the ring saw blade body to form an indirect connection. When the ring saw blade body rotates, it will drive the cutting tooth body to move together, thereby realizing the cutting of materials.

[0010] In a preferred embodiment, the present invention can be further configured such that the thickness of the fixing ring is less than the thickness of the annular saw blade body.

[0011] By adopting the above technical solution, since the thickness of the fixing ring is less than the thickness of the annular saw blade body, the friction area between the saw blade and the material is reduced, and the temperature generated by friction during cutting is lowered.

[0012] In a preferred embodiment, the present invention can be further configured such that the silencing tooth assembly includes a silencing tooth body, and a V-shaped groove is provided on one side of the silencing tooth body.

[0013] By adopting the above technical solution, the design of the silencing tooth body can effectively disrupt and disperse the sound waves generated by vibration, thereby reducing the occurrence of resonance. To further enhance this effect, the side of the silencing tooth body is also provided with V-shaped grooves, and multiple V-shaped grooves can be provided. Through this design, the disruption and dispersion effect of sound waves is significantly improved, and the probability of resonance is reduced accordingly.

[0014] In a preferred embodiment, the present invention can be further configured such that the annular saw blade body, the fixing ring, and the silencer tooth body are an integrated structural design.

[0015] By adopting the above technical solution, the structural strength is increased by integrating the annular saw blade body, the fixing ring, and the silencer tooth body into a single structure.

[0016] In a preferred embodiment, the present invention can be further configured such that the thickness of the silencing tooth body is equal to the thickness of the fixed tooth.

[0017] By adopting the above technical solution, since the thickness of the silencing tooth body is equal to the thickness of the fixed tooth, the damping when the saw blade contacts the material being cut can be increased, the vibration of the saw blade can be suppressed, and the sawing stability and accuracy can be improved.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] 1. By incorporating a sound-absorbing tooth assembly into the volumetric groove, the sound waves are disrupted and dispersed, reducing noise generated by resonance.

[0020] 2. By using U-shaped and L-shaped noise reduction grooves together, the natural frequencies of the fixing ring and saw blade body are dispersed, resonance is avoided, noise amplification is reduced from the source, and the performance is enhanced. Attached Figure Description

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] Reference Figures 1-2 The present invention discloses a noise-reducing saw blade, comprising: an annular saw blade body 1 and a fixing ring 2 connected to its inner hole. The outer circular surface of the annular saw blade body 1 is connected with a plurality of cutting tooth assemblies 30 in an annular array. A volume groove 4 is provided between adjacent cutting tooth assemblies 30, and a noise-reducing tooth assembly 50 is provided in the volume groove 4.

[0030] It also includes several U-shaped noise-absorbing grooves 6 arranged in a ring array on the fixed ring 2, and L-shaped noise-absorbing grooves 7 are provided between adjacent U-shaped noise-absorbing grooves 6. One end of the L-shaped noise-absorbing groove 7 extends to the ring saw blade body 1 and communicates with the corresponding volume groove 4, and the other end extends to the fixed ring 2.

[0031] The cutting tooth assembly 30 includes a fixed tooth 31, the outer end of which has a fixing groove 32. A cutting tooth body 33 is connected within the fixing groove 32. The cutting tooth body 33 is connected to the annular saw blade body 1 via the fixed tooth 31: the fixed tooth 31 is connected to the annular saw blade body 1, and the cutting tooth body 33 is fixed within the fixing groove 32 of the fixed tooth 31. This structure creates an indirect connection between the cutting tooth body 33 and the annular saw blade body 1. When the annular saw blade body 1 rotates, it drives the cutting tooth body 33 to move together, thereby achieving material cutting.

[0032] The thickness of the retaining ring 2 is less than the thickness of the annular saw blade body 1. Because the thickness of the retaining ring 2 is less than the thickness of the annular saw blade body 1, the friction area between the saw blade and the material is reduced, thus lowering the temperature generated by friction during cutting.

[0033] The noise-absorbing tooth assembly 50 includes a noise-absorbing tooth body 51, with a V-shaped groove 52 on one side. The noise-absorbing tooth body 51 effectively disrupts and disperses sound waves generated by vibration, thereby reducing resonance. To further enhance this effect, the side of the noise-absorbing tooth body 51 is also provided with a V-shaped groove 52, and multiple V-shaped grooves 52 can be provided. Through this design, the noise disruption and dispersion effect is significantly improved, and the probability of resonance is reduced accordingly.

[0034] The annular saw blade body 1, the fixing ring 2, and the silencer tooth body 51 are designed as an integrated structure. This integrated design increases the structural strength.

[0035] The thickness of the silencing tooth body 51 is equal to the thickness of the fixed tooth 31. Since the thickness of the silencing tooth body 51 is equal to the thickness of the fixed tooth 31, the damping when the saw blade contacts the material being cut can be increased, the vibration of the saw blade can be suppressed, and the sawing stability and accuracy can be improved.

[0036] The implementation principle of this embodiment is as follows: During use, the fixing ring 2 of the saw blade is installed on the rotating shaft of the cutting equipment. The rotating shaft drives the saw blade to rotate at high speed. At this time, several cutting tooth assemblies 30 on the outer circle of the annular saw blade body 1 will cut the material. However, during the cutting process, there will be a lot of friction between the cutting tooth assembly 30 and the material. In addition, the vibration of the saw blade itself will generate strong noise. By setting the sound-absorbing tooth assembly 50 in the volume groove 4, the saw blade can effectively disturb and disperse the sound waves generated by the vibration, reduce the resonance phenomenon, and thus achieve the purpose of reducing noise. At the same time, the use of the U-shaped sound-absorbing groove 6 breaks the overall rigid structure of the fixing ring 2, so that the natural frequency of the fixing ring can be dispersed, thereby avoiding resonance. The use of the L-shaped sound-absorbing groove 7 breaks the overall rigid structure of the fixing ring 2 and the annular saw blade body 1, so that their fixed frequencies are dispersed, which also plays a role in avoiding resonance. Through these designs, the amplification of noise is reduced from the source, and the performance of the saw blade is significantly enhanced.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
