Description

Technical Field

[0001] This utility model belongs to the field of diamond saw blade technology, and in particular relates to an ultra-thin hot-pressed diamond saw blade. Background Technology

[0002] Ultra-thin hot-pressed diamond saw blades are widely used in the processing of hard and brittle materials such as stone, ceramics, and glass. Due to their thinner thickness, these blades can achieve precise cutting and reduce cutting losses, leading to a continuous increase in demand in fields such as construction and decoration, and building materials processing. With increasing demands for processing efficiency, users are also placing higher requirements on the stability, ease of maintenance, and service life of saw blades.

[0003] Most ultra-thin diamond saw blades currently on the market adopt a one-piece structure, which often requires replacement of the entire blade after wear, resulting in high operating costs. At the same time, the saw blade easily generates a lot of heat during high-speed cutting, and the heat is difficult to dissipate quickly, which can easily cause the saw blade to deform and affect cutting accuracy. To address this issue, an ultra-thin hot-pressed diamond saw blade is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an ultra-thin hot-pressed diamond saw blade that is easy to replace, has reusable clamping and fixing plates, and has good heat dissipation and chip removal effects, thus solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An ultrathin hot-pressed diamond saw blade includes: a saw blade, with a clamping plate and a fixing plate respectively provided on both sides of the saw blade. The saw blade is arranged in a ring shape. A plurality of evenly distributed support plates are fixed on the side of the fixing plate near the saw blade. Each of the two support plates has a threaded hole on one side. Two fixing bolts are inserted into one side of the clamping plate. The two fixing bolts are threadedly connected to the two threaded holes respectively.

[0007] The clamping plate and the fixing plate are fixed by connecting the fixing bolt to the threaded hole. The saw blade is clamped between the clamping plate and the fixing plate. The clamping plate and the fixing plate are supported by the supporting plate to leave a cavity between them.

[0008] Multiple positioning elements are evenly arranged between the saw blade and the fixed plate to position the saw blade.

[0009] As a further embodiment of this utility model, the positioning component includes a limiting post and a limiting groove. The limiting post is fixed on the side of the fixing plate near the saw blade, and the limiting groove is disposed on the inner circumference of the saw blade. When the saw blade and the fixing plate are combined, the limiting post is located in the limiting groove.

[0010] As a further embodiment of this utility model, multiple heat dissipation grooves are provided on the opposite side of the clamping piece and the fixing piece, and one end of the heat dissipation groove extends to the outer circumferential wall of the clamping piece and the fixing piece, respectively.

[0011] As a further improvement of this invention, the heat dissipation groove is arc-shaped.

[0012] As a further improvement of this utility model, multiple through-holes are provided on one side of both the clamping piece and the fixing piece.

[0013] As a further improvement of this utility model, a through fixing hole is provided at the center point of both the clamping piece and the fixing piece.

[0014] As a further embodiment of this invention, the outer circumferential wall of the saw blade is provided with a plurality of equally spaced chip discharge ports.

[0015] Working principle: During assembly, align the limiting groove on the saw blade with the limiting post on the fixing plate, then join the two together. Next, place the clamping plate on the other side of the saw blade and align the fixing bolt with the threaded hole. After locking the fixing bolt, the connection between the saw blade, clamping plate, and fixing plate is completed. When the saw blade is damaged, it can be easily replaced. The clamping plate and fixing plate can be recycled, reducing material waste and lowering operating costs. Then, connect it to the equipment through the fixing hole according to the installation direction of the saw blade. During use, the saw blade, clamping plate, and fixing plate rotate. During rotation, air can enter the cavity between the clamping plate and fixing plate through the heat dissipation groove and be discharged through the air outlet. The air flow can improve the heat dissipation effect of the saw blade and facilitate continuous use.

[0016] The embodiments of this utility model have the following beneficial effects:

[0017] In this invention, the saw blade is precisely fixed between the clamping plate and the fixed plate through the positioning cooperation of the limiting post and the limiting groove, and the locking connection of the fixing bolt and the threaded hole, thus preventing circumferential displacement during cutting. After the saw blade wears out, it can be replaced simply by loosening the fixing bolt. The clamping plate and the fixed plate can be reused, reducing material waste and lowering long-term operating costs.

[0018] In this invention, the cavity formed by the support plate, combined with the ventilation structure of the arc-shaped heat dissipation groove and the air outlet, allows air to quickly enter the cavity and be discharged when the saw blade rotates, thus carrying away the heat generated during cutting and preventing the saw blade from deforming due to high temperature.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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 without creative effort are within the protection scope of the present utility model.

[0026] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0027] In one embodiment: Please refer to Figures 1-3 As shown, this embodiment provides a saw blade, including a saw blade 1, which is manufactured using a hot-pressing process and has an overall annular structure. Multiple equidistant chip discharge ports 4 are integrally formed on the outer circumference of the saw blade 1 to carry away material chips during cutting, with a uniform spacing between adjacent chip discharge ports 4. During cutting, the chips generated by the high-speed rotating saw blade 1 can quickly leave the cutting area through the chip discharge ports 4, preventing chip accumulation between the saw blade 1 and the material to be cut, reducing cutting resistance and lowering the wear rate of the saw blade 1.

[0028] Both the clamping plate 2 and the fixing plate 3 are forged from No. 45 steel. Their structural dimensions are matched, and each has a through fixing hole 11 at its center point for connection to the cutting equipment. On the side of the clamping plate 2 closest to the saw blade 1, two cylindrical fixing bolts 5 are movably inserted. The two fixing bolts 5 are symmetrically distributed about the center of the clamping plate 2, with external threads machined on their outer walls and chamfered ends for easy installation. On the side of the fixing plate 3 closest to the saw blade 1, multiple evenly distributed support plates 7 are integrally formed. The support plates 7 have a fan-shaped structure, with a thickness adapted to the overall structural requirements, and are arranged radially around the center of the fixing plate 3. On the side of two opposing support plates 7 furthest from the center of the fixing plate 3, threaded holes 6 matching the fixing bolts 5 are provided. The depth of the threaded holes 6 matches the length of the fixing bolts 5, ensuring full engagement between the two.

[0029] Multiple positioning components are provided between the saw blade 1 and the fixed plate 3. These positioning components consist of limiting posts 9 and limiting grooves 10. The limiting posts 9 are cylindrical structures, fixed to the side of the fixed plate 3 near the saw blade 1 by welding, and their height is consistent with the thickness of the support plate 7. The limiting grooves 10 are formed on the inner circumference of the saw blade 1. The groove opening size matches the diameter of the limiting posts 9, the groove depth matches the height of the limiting posts 9, and the number of grooves is consistent with the limiting posts 9 and evenly distributed. During assembly, the limiting grooves 10 on the saw blade 1 are aligned with the limiting posts 9 on the fixed plate 3, and then the two are joined together. After the limiting posts 9 are embedded in the limiting grooves 10, the saw blade 1 is precisely positioned on the fixed plate 3, preventing circumferential displacement and ensuring the rotational stability of the saw blade 1 during subsequent cutting.

[0030] After assembling the saw blade 1 and the fixing plate 3, place the clamping plate 2 on the other side of the saw blade 1. Adjust the position of the clamping plate 2 so that the two fixing bolts 5 are aligned with the threaded holes 6 on the two support plates 7. Screw the fixing bolts 5 into the threaded holes 6 and lock them in place. At this time, the saw blade 1 is stably clamped between the clamping plate 2 and the fixing plate 3. The support plates 7 provide effective support for the clamping plate 2, leaving a cavity between the clamping plate 2 and the fixing plate 3 with a height consistent with the thickness of the support plates 7. This cavity provides space for heat dissipation of the saw blade 1. When the saw blade 1 becomes worn or damaged due to long-term use, simply use a wrench to rotate the fixing bolts 5 counterclockwise to unscrew them from the threaded holes 6. The clamping plate 2 can then be removed and a new saw blade 1 can be replaced. The clamping plate 2 and the fixing plate 3 can be reused, reducing material waste and lowering operating costs.

[0031] This application can be used in the field of diamond saw blades, or in other fields applicable to this application.

[0032] In another embodiment: refer to Appendix Figures 1-3 An ultra-thin hot-pressed diamond saw blade is applied in the field of diamond saw blades. The structure of this embodiment is basically the same as that of the aforementioned embodiments, except that:

[0033] Multiple arc-shaped heat dissipation grooves 8 are provided on the opposite side of the clamping plate 2 and the fixing plate 3, with one end extending to the outer circumferential wall of the clamping plate 2 and the fixing plate 3. Multiple through vent holes 12 are also provided in the edge area of ​​the clamping plate 2 and the fixing plate 3. The vent holes 12 are circular or square holes and are connected to the cavity between the clamping plate 2 and the fixing plate 3.

[0034] The saw blade 1 can be connected to the equipment via the fixing hole 11 according to its installation direction and then put into use. During use, the saw blade 1, clamping plate 2, and fixing plate 3 rotate synchronously with the output shaft of the equipment. During rotation, external air enters the cavity between the clamping plate 2 and the fixing plate 3 through the arc-shaped heat dissipation groove 8, making full contact with the saw blade 1, which generates heat at high speed. The air that absorbs heat is then quickly discharged through the air outlet 12, forming a continuous airflow. This effectively removes the heat generated by the saw blade 1, preventing performance degradation or deformation due to overheating, improving the heat dissipation effect of the saw blade 1, and facilitating continuous long-term use.
