Description

Technical Field

[0001] This utility model relates to a saw blade, specifically a saw blade for processing fiberglass boards. Background Technology

[0002] Fiberglass board is a new type of composite material sheet made of glass fiber and resin. It uses high-quality alkali-free glass fiber as raw material and is manufactured through high-temperature and high-pressure lamination, resulting in excellent physical properties such as high strength, corrosion resistance, and good insulation. Fiberglass boards require a saw blade for cutting during processing.

[0003] Existing fiberglass board processing saw blades have a complex and poorly designed structure. Their pointed ends are typically not specially designed, meaning they can only tear the fiberglass board by high-speed rotation of the pointed end. However, the contact between the pointed end and the fiberglass board during cutting generates significant friction, and the pointed end cannot directly compress the cutting area, resulting in irregular cross-sections and excessive debris. Furthermore, existing saw blades require tools to remove all the pointed ends after damage, a cumbersome and time-consuming process. Therefore, the inventor has improved the structure of the fiberglass board processing saw blade. Utility Model Content

[0004] The purpose of this utility model is to provide a saw blade for processing fiberglass boards. This saw blade has a simple structure and reasonable design, which can tear fiberglass boards more quickly and efficiently, improving cutting efficiency. During the tearing process, the arc-shaped part squeezes the material at the cross-section of the fiberglass board towards the inside of the fiberglass board. The squeezing effect of the arc-shaped part reduces the irregularity of the joint after cutting, reduces debris, and realizes tool-free replacement of the blade, making maintenance simpler, more convenient and faster, saving time and solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a saw blade for processing fiberglass boards, the saw blade comprising a central disc, a fixing structure and a cutting blade located on the fixing structure, the fixing structure comprising a fixing ring and a positioning seat, wherein the fixing ring and the positioning seat are distributed at both ends of the central disc, a plurality of sliding grooves and a receiving groove communicating with the plurality of sliding grooves are provided at the end of the positioning seat away from the fixing ring, wherein the openings of the plurality of receiving grooves are located at the outer edge of the positioning seat, the plurality of sliding grooves are distributed in the circumferential direction of the positioning seat, and each of the plurality of sliding grooves is provided with a slidable lever, each of the plurality of levers is connected to a sliding rod, each of the plurality of receiving grooves is provided with a spring and an insert connected to the spring, the ends of the plurality of springs away from the inserts are connected to the inner wall of the receiving groove, the ends of the plurality of sliding rods away from the plurality of levers pass through the plurality of springs and are connected to the plurality of inserts, the cutting blade comprising a substrate and a plurality of cutting heads fixed in the circumferential direction of the substrate, the cutting head comprising a fixed end and a pointed tip provided on the fixed end, and an arc-shaped portion provided at the end of the fixed end near the fixing ring.

[0006] Preferably, both the fixing ring and the positioning seat are fixed to the central disk, and both the fixing ring and the positioning seat are coaxially arranged with the central disk.

[0007] Preferably, the substrate is sleeved on the outside of the central disk, and the two sides of the substrate are respectively attached to the fixing ring and the insert. Therefore, the fixing ring and the insert can be used to limit the two sides of the substrate respectively, so that the multiple cutting heads are firmly fixed on the outside of the central disk.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a saw blade for processing fiberglass boards. The saw blade includes a central disc, a fixed structure and a cutting blade located on the fixed structure. The overall structure is simple and reasonably designed. The cutting blade includes a substrate and multiple cutting heads fixed in the circumferential direction of the substrate. Each cutting head includes a fixed end and a pointed tip on the fixed end. An arc-shaped part is provided at the end of the fixed end near the fixed ring. By providing an arc-shaped part on the cutting head, the pointed tip continuously enters the interior of the fiberglass board during the cutting process. Because the arc-shaped part protrudes outward, it exerts a certain pressure on the fiberglass board during cutting, directly squeezing the fiberglass board. This allows the pointed tip to tear the fiberglass board more quickly and efficiently, improving the cutting efficiency. During the tearing process, the arc-shaped part squeezes the material at the cross-section of the fiberglass board towards the interior of the fiberglass board. The squeezing effect of the arc-shaped part reduces the irregularity of the joint after cutting and reduces debris, making it highly practical.

[0014] 2. The fixing structure of this utility model includes a fixing ring and a positioning seat. Multiple sliding grooves and receiving slots communicating with the fixing ring are provided at the end of the positioning seat away from the fixing ring. The multiple sliding grooves are distributed along the circumference of the positioning seat, and each sliding groove contains a slidable lever. Each lever is connected to a sliding rod. Each receiving slot contains a spring and a piece connected to the spring. The ends of the springs away from the pieces are connected to the inner wall of the receiving slot. The ends of the sliding rods away from the levers pass through the springs and connect to the pieces. When the tip is damaged and needs replacement, simply pull the levers to retract the springs and cause the pieces to retract into the receiving slots. Then, the substrate and its cutting head can be removed from the central plate and replaced, thus achieving tool-free replacement of the cutting head. This makes maintenance simpler, more convenient, and faster, saving time and making it suitable for widespread use. Attached Figure Description

[0024] Please see Figure 1 One embodiment of this utility model is a saw blade for processing fiberglass boards. The saw blade for processing fiberglass boards includes a central disk 1, a fixing structure 2 and a cutting blade 3 located on the fixing structure 2.

[0025] Please see Figures 2 to 3 The fixing structure 2 includes a fixing ring 21 and a positioning seat 22, wherein the fixing ring 21 and the positioning seat 22 are distributed at both ends of the central disk 1. The fixing ring 21 and the positioning seat 22 are both fixed to the central disk 1, and the fixing ring 21 and the positioning seat 22 are both coaxially arranged with the central disk 1. The slice 3 includes a substrate 31 and a plurality of cutting heads 32 fixed in the circumferential direction of the substrate 31.

[0026] Please see Figure 4 At the end of the positioning seat 22 away from the fixing ring 21, there are multiple sliding grooves 221 and storage slots 222 communicating with the multiple sliding grooves 221 respectively. The openings of the multiple storage slots 222 are located at the outer edge of the positioning seat 22. In this embodiment, there are four sliding grooves 221 and four storage slots 222. The multiple sliding grooves 221 are distributed in the circumferential direction of the positioning seat 22, and each of the multiple sliding grooves 221 is provided with a slidable lever 23. Each of the multiple levers 23 is connected to a sliding rod 24. The multiple sliding rods 24 are slidably disposed inside the positioning seat 22, and the ends of the multiple sliding rods 24 away from the levers 23 respectively enter the multiple storage slots 222. Each of the multiple storage slots 222 is provided with a spring 25 and an insert 26 connected to the spring 25. The ends of the multiple springs 25 away from the insert 26 are connected to the inner wall of the storage slot 222. The multiple sliding rods 24 are located away from the multiple storage slots 222. One end of each lever 23 passes through multiple springs 25 and connects to multiple inserts 26. One end of each insert 26 is attached to the substrate 31, and the other end is attached to the inner wall of multiple storage slots 222. The substrate 31 is fitted onto the outside of the central disk 1, and both sides of the substrate 31 are attached to the fixing ring 21 and the inserts 26, respectively. Therefore, the fixing ring 21 and the inserts 26 can be used to limit both sides of the substrate 31, so that multiple cutting heads 32 are firmly fixed to the outside of the central disk 1. When the tip 322 is damaged, the levers 23 are pushed toward the center of the central disk 1, causing the multiple springs 25 to retract and drive the multiple inserts 26 to retract into the multiple storage slots 222. Then the substrate 31 can be removed from the central disk 1 and replaced, thus realizing tool-free replacement of the slice 3. The maintenance process is simpler, more convenient and faster, saving time.

[0027] Please see Figure 5The cutting head 32 includes a fixed end 321 and a pointed end 322 disposed on the fixed end 321. An arc-shaped portion 323 is provided at the end of the fixed end 321 near the fixed ring 21, and a slope 3211 is formed at the end of the fixed end 321 near the positioning seat 22. The slope 3211 reduces the width of the pointed end 322, allowing the pointed end 322 to cut the fiberglass board better. An arc-shaped surface 3231 is formed at the end of the arc-shaped portion 323 near the fixed ring 21. During cutting, the pointed end 322 continuously enters the interior of the fiberglass board. Since the arc-shaped portion 323 protrudes outward, it exerts a certain pressure on the fiberglass board during cutting, directly squeezing the fiberglass board. This allows the pointed end 322 to tear the fiberglass board more quickly and efficiently, improving the cutting efficiency. During the tearing process, the arc-shaped portion 323 squeezes the material at the cross-section of the fiberglass board towards the interior of the fiberglass board. This squeezing action reduces the irregularity of the joint after cutting, thereby reducing debris.
