Description

Technical Field

[0001] This utility model relates to the field of diamond saw blade technology, and more specifically, to a noise-reducing diamond saw blade. Background Technology

[0002] A diamond saw blade is a cutting tool widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics. A diamond saw blade mainly consists of two parts: the matrix and the cutting head. The matrix is ​​the main supporting part that holds the cutting head together. The cutting head is the part that performs the cutting action during use. The cutting head wears down over time, while the matrix does not. The cutting head's ability to cut is due to the diamond it contains. Diamond, as the hardest known material, abrades and cuts the workpiece within the cutting head. The diamond particles are encased in metal within the cutting head, increasing its hardness.

[0003] Through exploration, for example, Chinese patent application CN201921372036.7 discloses a diamond circular saw blade with a noise reduction structure. By creating uniformly spaced slits on the outer side of the saw blade substrate, and creating a second end hole and a first end hole at each end of the slits, the sound generated during cutting can be blocked from propagating inside the saw blade substrate. At the same time, the vibration frequency of the saw blade substrate itself is changed during cutting, reducing the vibration frequency and making the sound generated during cutting less sharp and harsh. In addition, the second end hole, the slits, and the first end hole can accommodate deformation and eliminate thermal stress, preventing the product from deforming due to temperature rise, effectively improving the adverse effects caused by thermal deformation during use.

[0004] However, when the above solution is used, noise reduction and heat dissipation are achieved through the seam and the first and second end holes. Cutting is achieved by the high-speed rotation of the cutter head in contact with the workpiece, which causes the saw blade to vibrate and generate noise. The noise reduction and heat dissipation effect is not ideal. Furthermore, the above solution cannot avoid the damage of the cutter head during long-term use. When the cutter head is damaged, the entire saw blade needs to be replaced, resulting in waste. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a noise-reducing diamond saw blade. The technical problem to be solved is that the noise reduction and heat dissipation effect is not ideal, and the replacement of the entire saw blade due to the damage of the cutter head results in waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing diamond saw blade, comprising a saw blade substrate:

[0007] The outer surface of the saw blade substrate is provided with a noise-reducing cutting device that can cut the workpiece by cutting, which can reduce vibration and noise, and can be easily replaced.

[0008] The noise reduction cutting device includes multiple slots, which are respectively opened on the outer surface of the saw blade base. Insert blocks are movably provided inside the slots. Hollow diamond triangular cutter heads are fixed at the upper end of the insert blocks. Cutting edges are fixed at both ends of the diamond triangular cutter heads. By inserting multiple insert blocks into multiple slots, when the saw blade base rotates, it can drive multiple diamond triangular cutter heads and cutting edges to rotate. Cutting is achieved through the cutting effect of the cutting edges.

[0009] The saw blade substrate is provided with a heat dissipation device that conducts heat to conduct heat and dissipate heat.

[0010] In a preferred embodiment, a through hole is provided on the inner side of the saw blade substrate, the through hole is connected to the slot, a micro bolt passes through the inner side of the through hole, and a nut limiting groove is provided at one end of the through hole. The micro bolt is inserted into the through hole and the slot, thereby limiting the insertion block.

[0011] In a preferred embodiment, a plate-shaped nut is movably provided inside the nut limiting groove, and the plate-shaped nut serves as the limiting bolt.

[0012] In a preferred embodiment, a limiting hole is formed on the inner side of the insert block, and the micro bolt passes through the inner side of the limiting hole and is threaded to the inner side of the plate nut.

[0013] In a preferred embodiment, the conductive heat dissipation device includes a heat dissipation groove formed on the outer surface of the saw blade substrate. One end of the heat dissipation groove is provided with a heat conduction groove. When the saw blade substrate rotates, the heat dissipation groove can bring airflow into the heat conduction groove, thereby cooling the copper ingot.

[0014] In a preferred embodiment, a copper ingot is fixedly provided inside the heat conduction groove. The copper ingot has high thermal conductivity and can conduct heat dissipation to the saw blade substrate.

[0015] In a preferred embodiment, the saw blade base has noise-absorbing lines on both sides, noise-diffusing holes at both ends of the noise-absorbing lines, and an installation groove on the inner side of the saw blade base.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a noise-reducing cutting device, which facilitates cutting by shaving, reducing vibration and noise, and allowing for easy replacement. This avoids the need to replace the entire saw blade due to blade head damage, preventing waste. Multiple inserts are inserted into multiple slots, and micro-bolts are inserted into the slots and limiting holes for positioning. The micro-bolts are threaded onto the slots by a plate nut, thus fixing the inserts. When the diamond triangular blade head is damaged, simply loosen the micro-bolts to remove the diamond triangular blade head from the saw blade base for replacement, eliminating the need to replace the entire saw blade and avoiding waste. Because the diamond triangular blade head has cutting edges at both ends, when the saw blade base rotates, it drives the diamond triangular blade head to rotate and cut. The internal cavity of the diamond triangular blade head is used for chip discharge, and cutting is performed by the cutting edges, thus reducing vibration and noise caused by blade head collision during cutting.

[0018] This invention incorporates a heat dissipation device that facilitates the conduction of heat from the saw blade substrate, thereby improving the saw blade's heat dissipation effect and extending its service life. Heat is transferred through copper ingots within the heat conduction grooves. Since copper is a copper product, and copper has excellent thermal conductivity, it can conduct and dissipate the temperature of the saw blade substrate. The high-speed rotation of the saw blade substrate drives the heat dissipation grooves to rotate, thus utilizing the heat dissipation grooves to air-cool the copper ingots, thereby improving the overall heat dissipation effect and extending the service life.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art of diamond saw blades without creative effort are within the scope of protection of the present utility model.

[0025] like Figure 1 and 2 As shown, this utility model provides a noise-reducing diamond saw blade, including a saw blade base 1: noise-reducing lines 4 are respectively opened on both sides of the saw blade base 1, and sound-diffusing holes 5 are opened at both ends of the noise-reducing lines 4. An installation groove 6 is opened on the inner side of the saw blade base 1.

[0026] In order to reduce the waste of replacing the entire saw blade due to the damage of the blade head, the outer surface of the saw blade base 1 is provided with a noise reduction cutting device 2 that can cut the cutting object by cutting. This device can reduce vibration and noise and can be easily replaced.

[0027] like Figure 3 As shown, the noise reduction cutting device 2 includes multiple slots 21, which are respectively opened on the outer surface of the saw blade base 1. Insert blocks 25 are movably arranged inside the slots 21. A hollow diamond triangular cutter head 27 is fixedly mounted on the upper end of the insert block 25. Cutting edges 28 are fixedly mounted at both ends of the diamond triangular cutter head 27. A through hole 29 is opened inside the saw blade base 1, communicating with the slots 21. A micro bolt 22 passes through the inside of the through hole 29. A nut limiting groove 23 is opened at one end of the through hole 29, and a plate nut 24 is movably arranged inside the nut limiting groove 23. Insert blocks 25... A limiting hole 26 is provided on the inner side. A miniature bolt 22 passes through the inner side of the limiting hole 26 and is threaded to the inner side of the plate nut 24. Multiple inserts 25 are inserted into multiple slots 21 respectively. The miniature bolt 22 is inserted into the slots 21 and the limiting hole 26 for limiting. The miniature bolt 22 is threaded to the plate nut 24, thereby fixing the inserts 25. When the diamond triangular cutter head 27 is damaged, the diamond triangular cutter head 27 can be removed from the saw blade base 1 and replaced simply by loosening the miniature bolt 22. There is no need to replace the entire saw blade, thus avoiding waste.

[0028] Because the diamond triangular cutter head 27 has cutting edges 28 at both ends, when the saw blade base 1 rotates, it drives the diamond triangular cutter head 27 to rotate and cut. The internal cavity of the diamond triangular cutter head 27 is used for chip discharge, and cutting is performed by the cutting edges 28, thus reducing the vibration noise caused by the cutter head colliding and cutting.

[0029] Furthermore, in order to improve the heat dissipation effect of the saw blade, a heat dissipation device 3 is provided on the inner side of the saw blade base 1 to conduct heat dissipation by conducting heat through the saw blade base 1.

[0030] like Figure 4 As shown, the heat dissipation device 3 includes a heat dissipation groove 31, which is formed on the outer surface of the saw blade base 1. A heat conduction groove 32 is formed at one end of the heat dissipation groove 31, and a copper ingot 33 is fixed inside the heat conduction groove 32. Heat is transferred through the copper ingot 33 in the heat conduction groove 32. Since the copper ingot 33 is a copper product, copper has good thermal conductivity, so it can conduct and dissipate the temperature of the saw blade base 1. The high-speed rotating saw blade base 1 drives the heat dissipation groove 31 to rotate. Therefore, the heat dissipation groove 31 is used to air-cool the copper ingot 33, which improves the overall heat dissipation effect and increases the service life.

[0031] The working principle is as follows: When in use, the output end of the cutting machine is connected to the mounting slot of this utility model, thereby fixing this utility model to the output end of the cutting machine. When cutting the object, the noise reduction cutting device 2 cuts the object, thus reducing vibration and noise. Through the detachable effect of the noise reduction cutting device 2, the diamond triangular cutter head 27 can be easily replaced, avoiding the problem of needing to replace the entire saw blade due to the damage of individual diamond triangular cutter heads 27, thereby reducing waste. During the cutting process, the heat dissipation device 3 improves the heat dissipation effect of this utility model, thereby increasing the service life of this utility model and improving the overall practicality of this utility model.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
