Abstract
Description
Technical Field
[0001] This utility model relates to the field of diamond saw blade technology, and in particular to a diamond saw blade. Background Technology
[0002] Diamond saw blades, commonly used in industrial sawing tools, play a crucial role in cutting hard and brittle materials such as concrete, refractory materials, stone, and ceramics. Their structure mainly consists of two parts: the matrix and the cutting head. The cutting head is typically composed of a matrix alloy and diamond particles in a specific ratio. The matrix alloy firmly holds the diamond particles, enabling efficient cutting of various hard materials. Currently, the entry angle of diamond saw blades is mostly designed to be positive, ranging from 5 to 12°. This angle generates a downward cutting force during the cutting process, suitable for the processing needs of most hard and brittle materials.
[0003] However, in practical applications, the inventors observed a series of technical problems when using diamond saw blades with a positive angle of entry to cut soft-material veneer engineered wood panels. During the cutting process, the surface and bottom edges of the panel curl outwards, accompanied by tearing and breakage, resulting in rough and uneven cut edges. This severely affects cutting accuracy and surface quality, reducing the effectiveness and processing efficiency of diamond saw blades in soft-material processing scenarios. Utility Model Content
[0004] The main technical problem solved by this utility model is to provide a diamond saw blade that improves the performance and processing efficiency in soft material processing scenarios.
[0005] To solve the above-mentioned technical problems, the present invention provides a diamond saw blade, comprising: a circular saw blade base, wherein a plurality of first welding stations are connected in an annular array on the outer circular surface of the circular saw blade base, and a second welding station fixed on the circular saw blade base is provided between adjacent first welding stations. Left saw teeth are welded to the first welding stations respectively, and right saw teeth are welded to the second welding stations respectively. A negative rake angle α, which is an upward cutting force, is provided between the line connecting the top cutting edge of the left saw tooth and the center of the circular saw blade base and the cutting surface of the left saw tooth. The negative rake angle α is provided between the line connecting the top cutting edge of the right saw tooth and the center of the circular saw blade base and the cutting surface of the right saw tooth.
[0006] The cutting surface of the left saw tooth is provided with a left transverse front angle b, and the cutting surface of the right saw tooth is provided with a right transverse front angle c. The included angles of the left transverse front angle b and the right transverse front angle c are equal and the inclination directions are symmetrically arranged.
[0007] The top surface of the left saw tooth is provided with a top surface inclination angle d, and the top surface of the right saw tooth is provided with the same top surface inclination angle d.
[0008] By adopting the above technical solution, in practical applications, the staggered arrangement of the left and right saw teeth, along with their special design of a negative rake angle 'a', effectively guides the left and right saw teeth to generate upward cutting force. This innovative design significantly weakens the rebound force of soft and brittle materials during the cutting process, thereby greatly reducing the probability of edge curling and chipping. Furthermore, both the left and right saw teeth are equipped with a top bevel angle 'd', which is paired with a left transverse rake angle 'b' on the left saw tooth and a right transverse rake angle 'c' on the right saw tooth. The synergistic effect of these angular parameters greatly improves the cutting sharpness of the diamond saw blade, significantly enhancing its performance and thus effectively improving overall processing efficiency.
[0009] In a preferred embodiment, the present invention can be further configured such that the angle d of the apex is 15-20°.
[0010] By adopting the above technical solution, the cutting sharpness of the diamond saw blade is enhanced because the top angle d is 15-20°.
[0011] In a preferred embodiment, the present invention can be further configured such that the negative front angle α is 12–25°.
[0012] By adopting the above technical solution, the left and right saw teeth are arranged in an alternating pattern, with their negative rake angle α set in the range of 12–25°. This angle range allows the saw teeth to direct the cutting force into the interior of soft materials when they cut into them, changing the direction of force on the material and effectively reducing the rebound force during the cutting process. Compared to conventional angle designs, this negative rake angle configuration can significantly reduce the risk of edge curling and chipping caused by springback in soft materials, ensuring the flatness of the cut surface and processing accuracy.
[0013] In a preferred embodiment, the present invention can be further configured such that the angle of the left lateral front angle b is 10-15° and the angle of the right lateral front angle c is 10-15°.
[0014] By adopting the above technical solution, both the left lateral front angle b and the right lateral front angle c are set in the range of 10-15°. This angle setting gives the sharp, tough corners of the left and right saw teeth unique cutting characteristics. During the cutting process, the sharp, tough corners of the saw teeth first cut into the soft material, completing the initial break. Subsequently, the cutting edges on the left and right saw teeth, with the help of the inward cutting force generated by the angle design, precisely divide the material.
[0015] In a preferred embodiment, the present invention can be further configured as follows: the first welding platform is provided with an opening groove one, the inner wall of the opening groove one is fixed to the two sides of the left saw tooth by welding, and the second welding platform is provided with an opening groove two, the inner wall of the opening groove two is fixed to the two sides of the right saw tooth by welding.
[0016] By adopting the above technical solution, by setting an opening slot one on the first welding platform, the welding area between the left saw tooth and the first welding platform is expanded, and the connection between the left saw tooth and the first welding platform is strengthened. By setting an opening slot two on the second welding platform, the connection between the right saw tooth and the second welding platform is strengthened.
[0017] In a preferred embodiment, the present invention can be further configured such that the circular saw blade base, the first welding station, and the second welding station are integrally cut.
[0018] By adopting the above technical solution, integrated cutting avoids the gaps and stress concentration points caused by splicing after separate processing, making the overall structure of the saw blade more compact and uniform, maintaining better dynamic balance during high-speed rotating cutting, and reducing cutting deviations caused by vibration.
[0019] In summary, this utility model has at least one of the following beneficial technical effects:
[0020] 1. By staggering the left and right saw teeth and giving them a special negative rake angle α, the upward cutting force of the left and right saw teeth can be effectively guided. This innovative design significantly weakens the rebound force of soft and brittle materials during the cutting process, thereby greatly reducing the probability of edge curling and chipping.
[0021] 2. Both the left and right saw teeth are equipped with a top bevel angle d, which is matched with the left transverse front angle b on the left saw tooth and the right transverse front angle c on the right saw tooth. The synergistic effect of these angle parameters greatly improves the cutting sharpness of the diamond saw blade, significantly enhances the saw blade's performance, and thus effectively improves the overall processing efficiency.

[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 1-3 This utility model discloses a diamond saw blade, comprising: a circular saw blade base 1, with a plurality of first welding stations 2 connected in a ring array on the outer circumference of the circular saw blade base 1, and a second welding station 3 fixed on the circular saw blade base 1 between adjacent first welding stations 2. Left saw teeth 4 are welded onto the first welding stations 2, and right saw teeth 5 are welded onto the second welding stations 3. A negative rake angle α6, with an upward cutting force, is provided between the line connecting the top edge of the left saw tooth 4 and the center of the circular saw blade base 1 and the cutting surface of the left saw tooth 4. The negative rake angle α6 is also provided between the line connecting the top edge of the right saw tooth 5 and the center of the circular saw blade base 1 and the cutting surface of the right saw tooth 5. The angle of the negative rake angle α6 is 12-25°. The left saw teeth 4 and the right saw teeth 5 are arranged in an alternating pattern, and their negative rake angle α6 is set in the range of 12-25°. This angle range allows the saw teeth to direct the cutting force into soft materials when they penetrate them, changing the direction of force on the material and effectively reducing the rebound force during the cutting process. Compared to conventional angle designs, this negative rake angle configuration can significantly reduce the risk of edge curling and chipping caused by springback in soft materials, ensuring the flatness of the cut surface and processing accuracy.
[0030] The cutting surface of the left saw tooth 4 has a left transverse front angle b7, and the cutting surface of the right saw tooth 5 has a right transverse front angle c8. The included angles of the left transverse front angle b7 and the right transverse front angle c8 are equal and symmetrically arranged in the direction of inclination. The angle of the left transverse front angle b7 is 10-15°, and the angle of the right transverse front angle c8 is 10-15°. Both the left transverse front angle b7 and the right transverse front angle c8 are set in the range of 10-15°. This angle setting gives the sharp and tough corners of the left saw tooth 4 and the right saw tooth 5 unique cutting characteristics. During the cutting process, the sharp and tough corners of the saw teeth first cut into the soft material, completing the initial break. Subsequently, the cutting surfaces of the left saw tooth 4 and the right saw tooth 5 use the inward cutting force generated by the angle design to accurately divide the material.
[0031] The top surface of the left sawtooth 4 is provided with a top surface tilt angle d9, and the top surface of the right sawtooth 5 is provided with the same top surface tilt angle d9; the angle of the top surface tilt angle d9 is 15-20°.
[0032] The first welding station 2 is provided with an opening groove 11, the inner wall of which is fixed to the two sides of the left saw tooth 4 by welding. The second welding station 3 is provided with an opening groove 12, the inner wall of which is fixed to the two sides of the right saw tooth 5 by welding. By providing an opening groove 11 on the first welding station 2, the welding area between the left saw tooth 4 and the first welding station 2 is increased, and the connection between the left saw tooth 4 and the first welding station 2 is strengthened. By providing an opening groove 12 on the second welding station 3, the connection between the right saw tooth 5 and the second welding station 3 is strengthened.
[0033] The circular saw blade base 1, the first welding station 2, and the second welding station 3 are cut as a single piece. The single-piece cutting avoids the gaps and stress concentration points caused by splicing after separate processing, making the overall structure of the saw blade more compact and uniform. It can maintain better dynamic balance when cutting at high speed and reduce cutting deviation caused by vibration.
[0034] The implementation principle of this embodiment is as follows: In practical applications, by arranging the left saw tooth 4 and the right saw tooth 5 in an alternating pattern and giving them a special design with a negative rake angle a6, the left saw tooth 4 and the right saw tooth 5 can be effectively guided to generate an upward cutting force. This innovative design significantly weakens the rebound force of soft and brittle materials during the cutting process, thereby greatly reducing the probability of edge curling and chipping. In addition, both the left saw tooth 4 and the right saw tooth 5 are equipped with a top toughness inclination angle d9, and are respectively matched with the left transverse rake angle b7 on the left saw tooth 4 and the right transverse rake angle c8 on the right saw tooth 5. The synergistic effect of these angle parameters greatly improves the cutting sharpness of the diamond saw blade, significantly enhances the use effect of the saw blade, and thus effectively improves the overall processing efficiency.
