Description

Technical Field

[0001] This utility model relates to the field of cutting saw blade technology, and in particular to a special saw blade for cutting ultra-thin diamond mesh window screens. Background Technology

[0002] A cutting saw blade is a circular tool used to cut materials to a predetermined shape and size. Diamond mesh screens are a common door and window protection and ventilation facility. Their main uses include: insect and bird prevention, ventilation, dust prevention and security, sun shading and privacy, as well as durability and maintenance. The material is corrosion resistant, easy to clean, and suitable for long-term use.

[0003] However, traditional saw blades typically use a single blade head shape (often a straight blade head or a single curved blade head). During the cutting process of diamond mesh window screens, insufficient or uneven contact area can easily occur, leading to local stress concentration. This can easily cause the yarn to tear or break, making it impossible to cut the yarn smoothly, thus affecting the smoothness and efficiency of the saw blade cutting.

[0004] Therefore, those skilled in the art have provided a special saw blade for cutting ultra-thin diamond mesh screens to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-thin saw blade specifically for cutting diamond mesh screens. This saw blade features a cutting structure with both a flat cutter head and an arc-shaped cutter head. Combined with obliquely arranged saw teeth, it can perform sliding cuts on the diamond mesh screen threads. The combination of the two cutter heads provides a more uniform contact area during feeding, reducing localized high stress concentration, lowering the risk of thread jumping and slippage during cutting, and reducing the probability of thread tearing and breakage during cutting. This, in turn, improves the efficiency and stability of the saw blade's cutting performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A special saw blade for cutting ultra-thin diamond mesh window screens includes a mounting base. A cutting structure is provided in the middle of the outer wall of the mounting base. The cutting structure includes a saw plate. Multiple saw teeth are fixedly connected to the outer wall of the saw plate. Flat cutter heads and arc-shaped cutter heads are fixedly connected to the outer walls of the saw teeth respectively.

[0008] The outer walls of both the upper and lower surfaces of the cut structure are provided with heat-conducting structures. The heat-conducting structures include a fixed groove, a strip groove, and a circular groove. An annular heat sink is fixedly connected to the inner wall of the fixed groove. Multiple heat-conducting strips are fixedly connected to the outer wall of the annular heat sink. A heat-conducting sheet is fixedly connected to the end of each heat-conducting strip away from the annular heat sink.

[0009] Through the above technical solution, the saw blade is equipped with a heat-conducting structure. Under the guidance of the heat-conducting strip, the heat absorbed by the heat-conducting plate on the saw teeth can be transferred to the annular heat sink, thereby reducing the rate at which the saw teeth temperature rises and reducing cutting errors caused by thermal softening, thermal deformation, and thermal expansion. In addition, the heat-conducting strip and heat-conducting plate made of aluminum alloy can provide auxiliary reinforcement to the saw plate and saw teeth, thereby improving the overall toughness and stability of the saw blade and thus improving the safety of the saw blade in use.

[0010] Furthermore, the saw blade is fixedly connected to the center of the outer wall of the mounting base, and multiple heat-conducting and chip-removing grooves are formed around the periphery of the upper surface of the saw blade.

[0011] The above technical solution enables the cutting debris to be discharged through the heat-conducting chip removal groove and to be cooled.

[0012] Furthermore, the saw teeth are made of high-speed steel, and both the flat and curved blades are made of tungsten carbide.

[0013] Furthermore, the fixing grooves are respectively formed on the upper and lower surfaces of the saw blade;

[0014] The above technical solution enables the annular heat sink to dissipate the heat conducted from the saw blade and the heat-conducting strip.

[0015] Furthermore, the strip grooves are respectively formed on the periphery of the upper and lower surfaces of the saw blade, and the heat-conducting strip is fixedly connected to the strip grooves;

[0016] The above technical solution enables the heat-conducting strip to conduct heat from the heat-conducting sheet through the strip groove.

[0017] Furthermore, the circular grooves are respectively formed on the upper and lower surfaces of the serrations, and the heat-conducting sheet is fixedly connected to the circular grooves;

[0018] The above technical solution enables the heat-conducting plate to absorb the heat from the saw teeth through the circular groove.

[0019] Furthermore, a limiting mounting groove is formed at the center of the upper surface of the mounting base;

[0020] The above technical solution enables the saw blade to be snapped into place on the required cutting equipment by setting a limiting installation groove, and the limiting installation groove can reduce the possibility of the saw blade accidentally loosening.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes an ultra-thin saw blade specifically for cutting diamond mesh screens. Compared with most traditional diamond mesh screen cutting saw blades, this saw blade has a cutting structure with a flat cutter head and an arc-shaped cutter head. Combined with obliquely arranged saw teeth, it can perform sliding cuts on the diamond yarn of the diamond mesh screen. The combination of the two cutter heads can provide a more uniform contact area during feeding, reduce local high stress accumulation, reduce the risk of yarn jumping and jumping off during the cutting process, and also reduce the probability of yarn tearing and breaking during cutting, thereby improving the efficiency and stability of the saw blade cutting.

[0023] 2. This utility model proposes an ultra-thin saw blade specifically for cutting diamond mesh window screens. Compared with most traditional diamond mesh window screen cutting saw blades, this saw blade is equipped with a heat-conducting structure. Under the guidance of the heat-conducting strip, the heat absorbed by the heat-conducting plate on the saw teeth can be transferred to the annular heat sink, thereby reducing the rate at which the saw teeth temperature rises and reducing cutting errors caused by thermal softening, thermal deformation, and thermal expansion. In addition, the heat-conducting strip and heat-conducting plate made of aluminum alloy can provide auxiliary reinforcement to the saw plate and saw teeth, thereby improving the overall toughness and stability of the saw blade and thus improving the safety of using the saw blade.

[0029] One embodiment provided by this utility model:

[0030] Reference Figure 1 , 2 3. A special saw blade for cutting ultra-thin diamond mesh window screens, comprising a mounting base 1, a cutting structure 2 provided in the middle of the outer wall of the mounting base 1, the cutting structure 2 including a saw blade 201, multiple saw teeth 202 fixedly connected to the outer wall of the saw blade 201, and flat cutter heads 204 and arc-shaped cutter heads 205 respectively fixedly connected to the outer wall of the saw teeth 202, and heat-conducting structures 3 provided on the outer walls of the upper and lower surfaces of the cutting structure 2, the heat-conducting structures 3 including a fixing groove 301, a strip groove 305 and a circular groove 306, an annular heat sink 302 fixedly connected to the inner wall of the fixing groove 301, and multiple heat-conducting strips 3 fixedly connected to the outer wall of the annular heat sink 302. 03. A heat-conducting strip 303 is fixedly connected to a heat-conducting plate 304 at the end away from the annular heat sink 302. The saw blade is provided with a heat-conducting structure 3. Under the guidance of the heat-conducting strip 303, the heat absorbed by the heat-conducting plate 304 on the saw teeth 202 can be guided and transferred to the annular heat sink 302, thereby reducing the rate of temperature rise of the saw teeth 202 and reducing cutting errors caused by thermal softening, thermal deformation and thermal expansion. In addition, the aluminum alloy heat-conducting strip 303 and heat-conducting plate 304 can provide auxiliary reinforcement for the saw plate 201 and the saw teeth 202, thereby improving the overall toughness and stability of the saw blade and thus improving the safety of the saw blade.

[0031] Reference Figure 1 , 2 3. The saw blade 201 is fixedly connected to the center of the outer wall of the mounting base 1. Multiple heat-conducting chip removal grooves 203 are formed around the periphery of the upper surface of the saw blade 201, allowing the cut chips to be discharged through the grooves and for heat dissipation. The saw teeth 202 are made of high-speed steel, while the flat blade head 204 and the arc-shaped blade head 205 are both made of tungsten carbide. Fixing grooves 301 are respectively formed on the upper and lower surfaces of the saw blade 201, allowing the annular heat sink 302 to dissipate the heat conducted from the saw blade 201 and the heat-conducting strips 303. Strip grooves 305 are respectively formed around the periphery of the upper and lower surfaces of the saw blade 201. The heat-conducting strip 303 is fixedly connected to the strip groove 305, so that the heat-conducting strip 303 can conduct heat to the heat-conducting sheet 304 through the strip groove 305. The circular groove 306 is respectively opened on the upper and lower surfaces of the saw tooth 202. The heat-conducting sheet 304 is fixedly connected to the circular groove 306, so that the heat-conducting sheet 304 can absorb heat from the saw tooth 202 through the circular groove 306. A limiting installation groove 4 is opened at the center of the upper surface of the mounting base 1. By setting the limiting installation groove 4, the saw blade can be snapped onto the required cutting equipment, and the limiting installation groove 4 can reduce the possibility of the saw blade accidentally loosening.

[0032] Working principle: First, the saw blade is installed on the cutting equipment via the mounting base 1. It is securely fixed under the limiting positioning of the mounting groove 4. When the equipment is started, the ultra-thin saw blade rotates counter-clockwise, allowing the diamond wire on the diamond mesh screen to slide sequentially along the alloy flat blade 204 and the arc-shaped blade 205 for smoother cutting. During the cutting process, the friction between the blade and the diamond wire generates heat that accumulates on the saw teeth 202. This heat is first absorbed and guided by the heat-conducting plate 304, and then conducted to the annular heat sink 302 through the heat-conducting strip 303. The large contact area between the annular heat sink 302 and the air improves heat dissipation efficiency. Combined with the heat dissipation capabilities of the heat-conducting plate 304 and the heat-conducting strip 303, heat dissipation is efficiently guided, reducing heat accumulation on the saw teeth 202 and the blade, thus lowering the heat generated during saw blade cutting. Furthermore, the aluminum alloy heat-conducting plate 304 and the heat-conducting strip 303 enhance the strength of the ultra-thin saw blade while conducting heat.
