Abstract
Description
Technical Field
[0001] This utility model relates to the field of filing and grinding machine technology, and in particular to a novel filing and grinding machine saw blade. Background Technology
[0002] In fields such as metal processing and wood processing, filing machines are commonly used processing equipment, and the saw blade, as an important component of the filing machine, has a crucial impact on processing quality and efficiency.
[0003] Traditional saw blades for filing machines have many problems during use. For example, the saw blades have poor wear resistance, and the teeth are prone to wear after prolonged use, leading to decreased sawing accuracy and unstable processing quality. The saw blades also have poor heat dissipation performance; during high-speed operation and long-term work, the heat generated by the saw blade is difficult to dissipate quickly, causing the saw blade temperature to rise, which in turn affects the strength and toughness of the saw blade and shortens its service life. In addition, the installation fit between traditional saw blades and filing machines is not tight enough, and loosening is prone to occur during operation, affecting the stability and safety of processing. Therefore, we have proposed a new type of saw blade for filing machines to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of saw blade for filing and grinding machines, which achieves efficient and precise sawing, good heat dissipation, wear resistance and durability, and convenient assembly and disassembly through variable pitch saw teeth, wavy heat dissipation grooves, wear-resistant coating and convenient detachable structure, thereby improving processing quality and efficiency.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel saw blade for a filing and grinding machine, comprising a saw blade seat mounted on a filing and grinding machine, a saw blade body mounted on the saw blade seat via a detachable structure, the bottom of the saw blade body being provided with saw teeth, and the saw teeth being configured with variable pitch; the surface of the saw blade body being provided with a wear-resistant coating, and the saw blade body being provided with a plurality of heat dissipation grooves along the length direction, the heat dissipation grooves being wavy; the saw blade seat being provided with a mounting hole, a mounting rod being mounted on the rear inner wall of the mounting hole, and the saw blade body being provided with a mounting hole adapted to the mounting rod.
[0006] By adopting the above technical solutions, through variable pitch saw teeth, wavy heat dissipation grooves, wear-resistant coatings, and convenient detachable structures, efficient and precise sawing, good heat dissipation, wear resistance and durability, and convenient assembly and disassembly are achieved, thereby improving processing quality and efficiency.
[0007] A further feature of this invention is that the tooth pitch of the saw teeth increases sequentially from left to right, and the tooth pitch of the saw teeth increases sequentially from 8 to 12 mm from left to right. The front angle of the saw teeth is 15°-20° and the rear angle is 8°-12°.
[0008] By adopting the above technical solutions, the variable tooth pitch design and reasonable front and rear angle settings of the saw teeth enable the saw blade to cut into the material more smoothly during the sawing process, reduce sawing resistance, improve sawing efficiency and sawing accuracy, and are suitable for processing materials of different materials and thicknesses.
[0009] A further feature of this invention is that the spacing between adjacent heat dissipation slots is 5-8mm, and the depth of the heat dissipation slots is 1-1.5mm.
[0010] By adopting the above technical solution, the wavy heat dissipation grooves on the saw blade body increase the contact area between the saw blade and the air, which can more effectively promote heat dissipation. During the saw blade's operation, the heat generated can be quickly transferred to the air through the heat dissipation grooves, reducing the saw blade's temperature and thus ensuring the saw blade's strength and toughness during operation, reducing saw blade damage caused by excessive temperature.
[0011] A further feature of this invention is that the wear-resistant coating is formed by plasma spraying of tungsten carbide particles and nickel-based alloy, and the thickness of the wear-resistant coating is 0.3-0.5 mm.
[0012] By adopting the above technical solution, since the composite wear-resistant coating on the surface of the saw blade body is composed of tungsten carbide particles and nickel-based alloy coating, tungsten carbide has extremely high hardness and wear resistance, while nickel-based alloy ensures good bonding force between the coating and the saw blade body, which can effectively improve the wear resistance of the saw blade surface.
[0013] A further feature of this invention is that a positioning hole communicating with the mounting hole is provided on the front side of the saw blade body, and a positioning seat adapted to the positioning hole is installed at the bottom of the mounting rod.
[0014] By adopting the above technical solution, both ends of the saw blade body are respectively installed into the mounting holes, so that the mounting rod can pass through the fixing hole and the positioning seat can be installed into the positioning hole, thereby achieving the purpose of installing and positioning the saw blade body.
[0015] A further feature of this invention is that a clamping seat for fixing the saw blade body is slidably installed on the top inner wall of the mounting hole. The clamping seat has an insertion hole, and the mounting rod passes through the insertion hole and penetrates the clamping seat. One end of the mounting rod has an external thread, and a fixing nut for fixing the clamping seat is threaded on the external thread.
[0016] By adopting the above technical solution, the clamping seat is pushed so that the mounting plate passes through the insertion hole. The fixing nut is threaded onto the mounting rod, so that the fixing nut rotates while pressing along the mounting rod. The fixing nut can push the clamping seat to squeeze towards the saw blade body. The clamping seat can achieve the purpose of fixing the saw blade body, thereby facilitating the assembly and disassembly of the saw blade body.
[0017] A further feature of this invention is that a T-shaped hole is provided on the top inner wall of the mounting hole, and a T-shaped seat installed in the T-shaped hole is fixedly mounted on the top of the clamping seat.
[0018] By adopting the above technical solution, and by setting T-shaped holes and T-shaped seats, the clamping seat can be guided, thereby achieving the purpose of stable movement of the clamping seat.
[0019] The beneficial effects of this utility model are:
[0020] (1) Install both ends of the saw blade body into the mounting holes so that the mounting rod can pass through the fixing hole and the positioning seat can be installed into the positioning hole, so as to achieve the purpose of installing and positioning the saw blade body.
[0021] (2) By pushing the clamping seat, the mounting plate passes through the insertion hole. By threading the fixing nut onto the mounting rod, the fixing nut rotates while pressing along the mounting rod. The fixing nut can push the clamping seat towards the saw blade body. The clamping seat can fix the saw blade body, thus facilitating the assembly and disassembly of the saw blade body.
[0022] (3) The composite wear-resistant coating on the surface of the saw blade body is composed of tungsten carbide particles and nickel-based alloy coating. Tungsten carbide has extremely high hardness and wear resistance, while nickel-based alloy ensures good bonding between the coating and the saw blade body, which can effectively improve the wear resistance of the saw blade surface.
[0023] (4) The wave-shaped heat dissipation grooves on the saw blade body increase the contact area between the saw blade and the air, which can more effectively promote the dissipation of heat. During the operation of the saw blade, the heat generated can be quickly transferred to the air through the heat dissipation grooves to reduce the temperature of the saw blade, thereby ensuring the strength and toughness of the saw blade during operation and reducing the damage to the saw blade caused by excessive temperature.
[0024] (5) The variable tooth pitch design and reasonable front and back angle settings of the saw teeth enable the saw blade to cut into the material more smoothly during the sawing process, reduce sawing resistance, improve sawing efficiency and sawing accuracy, and are suitable for processing materials of different materials and thicknesses.

[0034] See Figures 1-4This utility model provides a novel saw blade for a filing and grinding machine, including a saw blade seat 101 mounted on a filing and grinding machine. A saw blade body 102 is mounted on the saw blade seat 101 via a detachable structure. The bottom of the saw blade body 102 is provided with saw teeth 103, and the saw teeth 103 are configured with variable tooth pitch. A wear-resistant coating 104 is provided on the surface of the saw blade body 102, and a plurality of heat dissipation grooves 105 are formed along the length direction on the saw blade body 102. The heat dissipation grooves 105 are wavy. An installation hole 201 is provided on the saw blade seat 101, and an installation rod 202 is installed on the rear inner wall of the installation hole 201. A fixing hole 203 adapted to the installation rod 202 is provided on the saw blade body 102.
[0035] Specifically, the tooth pitch of the saw teeth 103 increases sequentially from left to right, and the tooth pitch of the saw teeth 103 increases sequentially from 8 to 12 mm from left to right. The front angle of the saw teeth 103 is 15°-20° and the back angle is 8°-12°.
[0036] Specifically, the spacing between adjacent heat dissipation slots 105 is 5-8mm, and the depth of heat dissipation slots 105 is 1-1.5mm.
[0037] Specifically, the wear-resistant coating 104 is formed by plasma spraying of tungsten carbide particles and nickel-based alloy, and the thickness of the wear-resistant coating 104 is 0.3-0.5 mm.
[0038] Specifically, the saw blade body 102 has a positioning hole 301 on the front side that communicates with the fixing hole 203. The bottom of the mounting rod 202 is fitted with a positioning seat 302 that matches the positioning hole 301. A clamping seat 401 for fixing the saw blade body 102 is slidably installed on the top inner wall of the mounting hole 201. The clamping seat 401 has an insertion hole 402, and the mounting rod 202 passes through the insertion hole 402 and passes through the clamping seat 401. One end of the mounting rod 202 has an external thread, and a fixing nut 403 for fixing the clamping seat 401 is threaded on the external thread.
[0039] Specifically, a T-shaped hole 501 is provided on the top inner wall of the mounting hole 201, and a T-shaped seat 502 installed in the T-shaped hole 501 is fixedly installed on the top of the clamping seat 401.
[0040] Working principle: The two ends of the saw blade body 102 are respectively installed into the mounting holes 201, allowing the mounting rod 202 to pass through the fixing hole 203.

The fixing nut 403 pushes the clamping seat 401 towards the saw blade body 102, thus fixing the saw blade body 102 and facilitating its assembly and disassembly. The composite wear-resistant coating 104 on the surface of the saw blade body 102 is made of tungsten carbide. The blade is composed of granules and a nickel-based alloy coating. Tungsten carbide has extremely high hardness and wear resistance, while the nickel-based alloy ensures good adhesion between the coating and the saw blade body 102, effectively improving the wear resistance of the saw blade surface. The wave-shaped heat dissipation grooves 105 on the saw blade body 102 increase the contact area between the saw blade and the air, which can more effectively promote heat dissipation. During the saw blade's operation, the heat generated can be quickly transferred to the air through the heat dissipation grooves 105, reducing the temperature of the saw blade, thereby ensuring the strength and toughness of the saw blade during operation and reducing saw blade damage caused by excessive temperature. The variable tooth pitch design and reasonable front and rear angle settings of the saw teeth 103 enable the saw blade to cut into the material more smoothly during sawing, reducing sawing resistance, improving sawing efficiency and sawing accuracy, and making it suitable for processing materials of different materials and thicknesses.
