Description

Technical Field

[0001] The utility model relates to the technical field of circular saw blades, in particular to a carbide-tooth circular saw blade with an assembled structure. Background Technique

[0002] As a product of carbide cutting tools, carbide saw blades are specially made for cutting and grooving metal materials and are the most commonly used cutting tools in wood processing. The quality of carbide saw blades is closely related to the quality of processed products.

[0003] In the prior art, when installing a circular saw blade, it is usually installed on a cutting machine by using screws. However, the method of installing with screws is rather troublesome, and the screws are prone to thread slipping when the saw blade rotates. Moreover, when the existing circular saw blade cuts materials, the heat dissipation effect is poor, and the temperature cannot be dissipated well, which may cause the phenomenon of tooth burning, reducing the cutting quality of the device. Therefore, the existing device needs to be improved to meet the actual requirements. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a carbide-tooth circular saw blade with an assembled structure, which has the advantages of being convenient for quickly installing and disassembling the saw blade and having a good heat dissipation effect of the saw blade, and solves the above technical problems.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the utility model provides the following technical solutions: A carbide-tooth circular saw blade with an assembled structure includes a saw blade body and a rotating rod. Saw teeth are installed around the saw blade body. Heat dissipation holes are formed in the circumferential direction of the side end of the saw blade body. A sound insulation slot is installed in the circumferential direction of the side end of the saw blade body. A graphene heat dissipation strip is installed in the circumferential direction of the side end of the saw blade body. An installation block is fixedly installed at the side end of the saw blade body. A spring groove is formed at the bottom end of the installation block. A spring group is fixedly installed at the top end inside the spring groove. A clamping block is fixedly installed at the bottom end of the spring group. A clamping groove is formed on the outer wall of the rotating rod.

[0008] Preferably, six groups of saw teeth are provided, and the saw teeth are installed around the saw blade body through fastening bolts.

[0009] Through the above technical solution, since multiple groups of saw teeth are provided and are detachably installed around the saw blade body, when one saw tooth is damaged, only the damaged saw tooth needs to be replaced, which can save costs.

[0010] Preferably, the sound insulation slot is of a curved structure, and sound insulation holes are formed at both ends.

[0011] Through the above technical solution, by setting the sound-absorbing slits and sound-absorbing holes, the circular saw blade has a certain sound-absorbing ability, which can reduce noise pollution.

[0012] Preferably, a limit bolt is threadedly installed on the side end of the mounting block.

[0013] Through the above technical solution, when the limit bolt is rotated into the mounting block, the limit bolt can limit the clamping block to prevent the clamping block from moving.

[0014] Preferably, a pull ring is fixedly installed at the top end of the clamping block, and the pull ring penetrates through the top end of the mounting block.

[0015] Through the above technical solution, by pulling the pull ring upward, the upward movement of the pull ring can drive the clamping block to move upward, and the clamping block is disengaged from the clamping groove.

[0016] Compared with the prior art, the present utility model provides a cemented carbide tooth circular saw blade with an assembled structure, having the following beneficial effects:

[0017] 1. In the present utility model, by pulling the pull ring around, the movement of the pull ring can drive the clamping block to move into the spring groove. At this time, the spring group is compressed. Then, the saw blade body is sleeved on the outer wall of the rotating rod. After fixing the position, the positions of the clamping block and the clamping groove are made corresponding, and then the pull ring is released. The spring group loses the pulling force and needs to recover the deformation, thereby driving the clamping block to move into the clamping groove, so as to fix the saw blade body and the rotating rod by using the clamping block and the clamping groove. Finally, only by rotating the limit bolt inward can the clamping block be fixed.

[0018] 2. In the present utility model, by setting the sound-absorbing slits, the circular saw blade has a certain sound-absorbing ability, which can reduce noise pollution. By setting the heat dissipation holes and graphene heat dissipation strips, the saw blade body can be dissipated heat, improving the heat dissipation effect of the device body. At the same time, when a certain saw tooth is damaged, only the damaged saw tooth needs to be disassembled and replaced, which can save costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , a cemented carbide circular saw blade with an assembled structure, including a saw blade body 1 and a rotating rod 2. Saw teeth 3 are installed around the saw blade body 1. Heat dissipation holes 4 are provided on the circumferential side of the saw blade body 1. A sound insulation slot 5 is installed on the circumferential side of the saw blade body 1. Graphene heat dissipation strips 6 are installed on the circumferential side of the saw blade body 1. Mounting blocks 7 are fixedly installed on the side end of the saw blade body 1. Spring grooves 8 are provided at the bottom end of the mounting blocks 7. Spring groups 9 are fixedly installed at the top end inside the spring grooves 8. Clamping blocks 10 are fixedly installed at the bottom end of the spring groups 9. Card slots 11 are provided on the outer wall of the rotating rod 2.

[0026] Specifically, six groups of saw teeth 3 are provided, and the saw teeth 3 are installed around the saw blade body 1 through fastening bolts. The advantage is that since multiple groups of saw teeth 3 are provided and are detachably installed around the saw blade body 1, when one saw tooth 3 is damaged, only the damaged saw tooth 3 needs to be replaced, which can save costs.

[0027] Specifically, the sound insulation slot 5 has a curved structure, and sound insulation holes are provided at both ends. The advantage is that by providing the sound insulation slot 5 and the sound insulation holes, the circular saw blade has a certain sound insulation ability, which can reduce noise pollution.

[0028] Specifically, a limit bolt 12 is installed on the side end of the mounting block 7 by threading. The advantage is that when the limit bolt 12 is rotated into the mounting block 7, the limit bolt 12 can limit the clamping block 10 to prevent the clamping block 10 from moving.

[0029] Specifically, a pulling ring 13 is fixedly installed at the top end of the clamping block 10, and the pulling ring 13 passes through the top end of the mounting block 7. The advantage is that by pulling the pulling ring 13 upward, the upward movement of the pulling ring 13 can drive the clamping block 10 to move upward and make the clamping block 10 disengage from the card slot 11.

[0030] During use, by pulling the pull ring 13 in all directions, the movement of the pull ring 13 can drive the clamping block 10 to move into the spring groove 8. At this time, the spring group 9 is compressed. Then, the saw blade body 1 is sleeved on the outer wall of the rotating rod 2. After fixing the position, the positions of the clamping block 10 and the clamping groove 11 are made to correspond. Then, the pull ring 13 can be released. The spring group 9 loses the pulling force and needs to restore its deformation, thereby driving the clamping block 10 to move into the clamping groove 11, so as to fix the saw blade body 1 and the rotating rod 2 by using the clamping block 10 and the clamping groove 11. Finally, only by turning the limit bolt 12 inward can the clamping block 10 be fixed. By providing a sound-absorbing slit, the circular saw blade has a certain sound-absorbing ability, which can reduce noise pollution. By providing heat dissipation holes 4 and graphene heat dissipation strips 6, heat dissipation can be carried out on the saw blade body 1, improving the heat dissipation effect of the device body. At the same time, when a certain saw tooth 3 is damaged, only the damaged saw tooth 3 needs to be disassembled and replaced, which can save costs.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
