Description

Technical Field

[0001] This utility model relates to the field of saw blade equipment technology, specifically to a saw blade that is easy to remove chips. Background Technology

[0002] Saw blades are a general term for thin, circular cutting tools used to cut solid materials. Saw blades can be divided into: diamond saw blades for stone cutting; high-speed steel saw blades for metal cutting; and carbide saw blades for cutting solid wood, furniture, engineered wood, aluminum alloys, aluminum profiles, radiators, plastics, and PVC.

[0003] Chinese utility model CN2023208998542 proposes a "circular saw blade with convenient chip removal". This device includes a base, a cutting head, a cutting slit, a receiving groove, an annular flow channel, and a radial flow channel. During operation, chips from the cutting area enter the cutting slit and are compressed into the receiving groove. When the cutting slit and receiving groove separate from the cutting area, centrifugal force causes the chips to be ejected from both. While this device improves chip removal efficiency, the friction between the cutting head and the workpiece generates significant cutting heat, drastically shortening the cutting head's lifespan. This leads to tooth breakage, affecting the blade's normal operation. Since existing saw blades do not allow for cutting head replacement, subsequent tooth breakage necessitates replacing the entire blade, increasing operating costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a saw blade that is easy to remove chips. This solves the problem that in the prior art, when the saw blade tip comes into contact with the workpiece, the friction of the cutting surface generates a lot of cutting heat, which shortens the life of the tip. Moreover, the existing saw blade tips are not easy to replace, which means that when a tooth breaks, the entire saw blade needs to be replaced, which increases the cost of use.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a saw blade that facilitates chip removal, comprising:

[0007] The saw blade body has multiple chip removal grooves circumferentially arranged on the saw blade body, and a chip accumulation groove is also provided near the chip removal groove and located on the saw blade body. A heat conduction groove extends downward in the chip accumulation groove.

[0008] The mounting end includes a mounting groove formed on the saw blade body, a limiting protrusion and a connecting end provided near the mounting groove and on the saw blade body, and a blade is detachably connected in the mounting groove by an external bolt.

[0009] In some embodiments, a mounting hole is provided at the center of the saw blade body.

[0010] In some embodiments, the mounting groove has an opening on one side and a positioning block on the other side, the positioning block being used to extend into the blade.

[0011] In some embodiments, the connecting end includes a connecting screw hole, which includes a first hole, a second hole, and a third hole. The first hole is disposed on the side wall of the chip accumulation groove, and the second hole and the third hole are disposed on the outer wall of the saw blade body and communicate with the interior of the mounting groove. The blade is bolted to the interior of the first hole, the second hole, and the third hole.

[0012] In some embodiments, a mounting block is provided at the bottom of the blade, the mounting block is slidably connected in the mounting groove, and a positioning hole is provided on one side of the mounting block to cooperate with the positioning block.

[0013] In some embodiments, an extension plate is fixed to the left side of the mounting block, the extension plate has a screw hole that mates with the first hole, and the side wall of the mounting block has two screw holes that mate with the second hole and the third hole respectively.

[0014] In some embodiments, the bottom of the blade is provided with a limiting notch that mates with the limiting protrusion.

[0015] In some embodiments, the blade is further provided with a first included angle, the angle of the first included angle being α, and 3°≤a≤8°.

[0016] In some embodiments, the saw blade body is a tungsten carbide saw blade, and the blade is a hardened steel blade body.

[0017] In some embodiments, the length of the chip accumulation groove is less than the length of the heat conduction groove.

[0018] Compared with existing technologies, this utility model provides a saw blade with easy chip removal. Chip removal grooves are provided on the saw blade body to remove chips generated during cutting. Chip accumulation grooves are provided on the outer periphery of the saw blade body, and these grooves are evenly distributed along the circumference. These grooves allow waste chips generated during cutting to enter the chip accumulation grooves, preventing excessive chip accumulation in the chip removal grooves and ensuring proper cutting. Heat conduction grooves are also provided for effective heat conduction. An installation groove is provided on the saw blade body, with a limiting protrusion near the bottom of the installation groove. The blade is detachably connected to the installation groove via a connecting end, ensuring a tight fit between the bottom of the blade and the limiting protrusion, enhancing its integrity and ensuring the blade's working efficiency. Furthermore, since the blade is detachable, damaged sections can be individually disassembled. In addition to good chip removal, this design extends the service life of the saw blade body, significantly reducing user costs. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To address the problem that existing saw blades generate significant cutting heat during use due to friction between the saw blade tip and the workpiece, thus shortening the tip's lifespan, and the inconvenience of replacing existing saw blade tips necessitates replacing the entire blade when a tooth breaks, increasing operating costs, this invention provides a saw blade with easy chip removal. This design allows for individual replacement of the blade's individual blades while maintaining efficient chip removal, effectively extending the blade's lifespan.

[0028] It should be noted that the saw blade with easy chip removal described in this utility model is used in, but not limited to, the field of saw blades. For ease of explanation, this utility model only uses the application of the saw blade with easy chip removal in the field of saw blades as an example. The principle of the saw blade with easy chip removal in other types of equipment is essentially the same as that in the field of saw blades, and will not be described in detail here.

[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a saw blade that facilitates chip removal in one embodiment of the present invention. A saw blade that facilitates chip removal includes a saw blade body 1 and a mounting end 3. The saw blade body 1 has a plurality of chip removal grooves 2 circumferentially formed. Near the chip removal grooves 2 and located on the saw blade body 1, a chip accumulation groove 21 is also provided. A heat conduction groove 22 extends downward in the chip accumulation groove 21. The mounting end 3 includes a mounting groove 31 formed on the saw blade body 1. Near the mounting groove 31 and on the saw blade body 1, a limiting protrusion 32 and a connecting end 33 are provided. A blade 4 is detachably connected to the mounting groove 31 by an external bolt.

[0030] In this embodiment, a chip removal groove 2 is provided on the saw blade body 1 to remove the chips generated during the cutting process. A chip accumulation groove 21 is provided on the outer periphery of the saw blade body 1, and the chip accumulation groove 21 is evenly distributed along the circumference of the saw blade body 1. By providing the chip accumulation groove 21, the waste chips generated during the cutting of the saw blade body 1 can be placed into the chip accumulation groove 21, avoiding the situation where there are too many waste chips in the chip removal groove 2 and the cutting cannot be done well. The heat conduction groove 22 is provided to achieve the corresponding heat conduction effect. An installation groove 31 is provided on the saw blade body 1, and a limiting protrusion 32 is provided near the bottom of the installation groove 31. The blade 4 is detachably connected to the installation groove 31 through the connecting end 33, and the bottom of the blade 4 is tightly fitted with the limiting protrusion 32, making it more integrated. This can ensure the working efficiency of the blade 4. At the same time, since the blade 4 is a detachable connecting end 33, it can be disassembled individually when some blades are damaged. While having a good chip removal effect, it can extend the service life of the saw blade body 1 and greatly reduce the user's operating costs.

[0031] In one embodiment, please refer to Figure 1 - Figure 6 To facilitate the installation and removal of the blade 4 from the saw blade body 1, the mounting groove 31 has an opening on one side and a positioning block 311 on the other side. The positioning block 311 extends into the blade 4. The connecting end 33 includes a connecting screw hole 331, which includes a first hole 3311, a second hole 3312, and a third hole 3313. The first hole 3311 is located on the side wall of the chip collection groove 21, while the second hole 3312 and the third hole 3313 are located on the outer wall of the saw blade body 1 and communicate with the interior of the mounting groove 31. The interiors of the first hole 3311, the second hole 3312, and the third hole 3313 are all connected by bolts. The blade 4 is attached, and a mounting block 41 is provided at the bottom of the blade 4. The mounting block 41 is slidably connected in the mounting groove 31, and a positioning hole 411 that mates with the positioning block 311 is provided on one side of the mounting block 41. An extension plate 412 is fixed on the left side of the mounting block 41. A screw hole that mates with the first hole 3311 is provided on the extension plate 412. Two screw holes that mate with the second hole 3312 and the third hole 3313 are provided on the side wall of the mounting block 41. A limiting notch 42 that mates with the limiting protrusion 32 is provided at the bottom of the blade 4. A first included angle 43 is also provided on the blade 4. The angle of the first included angle 43 is α, and 3°≤a≤8°.

[0032] In this embodiment, the upper end of the mounting groove 31 is a flat end face, and an opening is provided on the left side of the mounting groove 31 to facilitate the blade 4 to drive the bottom mounting block 41 to slide into the mounting groove 31 from left to right, and to extend the positioning block 311 into the positioning hole 411 of the mounting block 41. An extension plate 412 is provided at the lower end of the mounting block 41, and screw holes are provided on the extension plate 412 to facilitate the overlap of the holes on the extension plate 412 with the first hole 3311. The extension plate 412 is then fastened to the inner wall of the chip accumulation groove 21 by bolts or screws. When the mounting block 41 extends into the mounting groove 31, the first... The second hole 3312 and the third hole 3313 coincide with the screw holes on the side wall of the mounting block 41. The mounting block 41 is also fastened to the saw blade body 1 by bolts, which makes the blade 4 more stable during operation. When it is necessary to replace the individual blade 4, only the bolts need to be removed to replace the blade 4 individually. The tilt angle of the blade 4 after installation is 7°, which makes it easier to cut softer materials, such as aluminum. The limiting notch 42 at the bottom of the blade 4 is set to cooperate with the limiting protrusion 32, which makes the assembly of the blade 4 and the saw blade body 1 more tight and integrated.

[0033] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The saw blade body 1 has a mounting hole 11 at its center. The saw blade body 1 is a tungsten carbide saw blade, and the blade 4 is a hardened steel blade. The length of the chip groove 21 is less than the length of the heat conduction groove 22.

[0034] In this embodiment, an installation hole 11 is opened at the center of the saw blade body 1 to facilitate normal installation of the saw blade body 1. The saw blade body 1 is made of tungsten carbide and the blade 4 is made of hardened steel, which greatly improves the service life of the saw blade body 1. The length of the heat conduction groove 22 is set to be longer than the length of the chip accumulation groove 21 in order to improve the heat dissipation effect of the saw blade.

[0035] To better understand this utility model, the following is combined with... Figures 1 to 6The technical solution of this utility model is described in detail as follows: A chip removal groove 2 is provided on the saw blade body 1 to remove the chips generated during the cutting process. A chip accumulation groove 21 is provided on the outer periphery of the saw blade body 1, and the chip accumulation groove 21 is evenly distributed along the circumference of the saw blade body 1. By providing the chip accumulation groove 21, the waste chips generated during the cutting of the saw blade body 1 can be placed into the chip accumulation groove 21, avoiding the situation where there are too many waste chips in the chip removal groove 2 and the cutting cannot be achieved well. In addition, the heat conduction groove 22 is provided to achieve the corresponding heat conduction effect. The blade 4 in this application is detachably connected to the mounting groove 31 of the saw blade body 1. The blade 4 drives the mounting block 41 to slide into the mounting groove 31 from left to right, and the positioning block 311 in the mounting groove 31 is engaged in the positioning hole 411 of the mounting block 41. At this time, the extension plate 412 is in close contact with the inner edge of the chip accumulation groove 21. The extension plate 412 is threaded to the first hole 3311 by external bolts, and the external bolts pass through the second hole 3312 and the third hole 3313, extending into the bolt holes on both sides of the mounting block 41 to complete the assembly of the blade 4. A limiting notch 42 is provided at the bottom of the blade 4 to cooperate with the limiting protrusion 32, which makes the assembly of the blade 4 and the saw blade body 1 more compact and stronger. Since the existing saw blade body 1 has the corresponding chip removal function, the blade 4 is prone to wear and tooth breakage during the cutting process. The blade 4 on the existing saw blade body 1 is not convenient to disassemble, which means that after tooth breakage, the entire saw blade body 1 needs to be replaced, which increases the user's operating cost and reduces the utilization efficiency of the saw blade body 1.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
