[0027] As Figures 1-3 shown, the embodiment of the present application provides a water-cooled saw blade, including a tool shank 1. A first flow channel 11 and at least one second flow channel 12 are arranged inside the tool shank 1. Each second flow channel 12 is respectively communicated with the first flow channel 11 inside the tool shank 1. The first flow channel 11 and the second flow channels 12 form several channels penetrating through both ends of the tool shank 1 inside the tool shank 1;

[0028] A rotating shaft 2, one end of the rotating shaft 2 is rotatably inserted inside the tool shank 1, and the other end of the rotating shaft 2 protrudes from the tool shank 1;

[0029] A cutting member 3, the cutting member 3 is detachably installed at one end of the rotating shaft 2 away from the tool shank 1, and the outlet of the second flow channel 12 at the end of the tool shank 1 faces the cutting member 3.

[0030] In this embodiment, both the first flow channel 11 and the second flow channel 12 are linear, and the cross-sectional shapes of the first flow channel 11 and the second flow channel 12 are circular or regular polygons. The rotating shaft 2 is coaxially arranged with the tool shank 1. At the inlet of the first flow channel 11 at one end of the tool shank 1 away from the cutting member 3, an external water pump is connected. The water pump can continuously supply cooling water. The cooling water enters from the first flow channel 11 and then sprays out through the second flow channel 12. Optionally, the cutting member 3 is a saw blade;

[0031] During operation, the water pump pumps the cooling water into the first flow channel 11, and then the cooling water is conveyed from the first flow channel 11 to the second flow channel 12. At this time, the cooling water is divided at the second flow channel 12. After being divided into several parts, it sprays out from multiple outlets of the second flow channel 12 to quickly dissipate heat from the cutting member 3;

[0032] By arranging the first flow channel 11 and the second flow channel 12 inside the tool shank 1, the cooling water can flow through the first flow channel 11 and the second flow channel 12. After being divided by the second flow channel 12, it sprays out from the outlets of multiple second flow channels 12 towards the cutting member 3 to quickly dissipate heat from the cutting member 3, reduce the wear speed and replacement frequency of the cutting member 3, and thus reduce costs.

[0033] In one embodiment, the second flow channel 12 is distributed around the rotating shaft 2.

[0034] In this embodiment, when there are two or more second flow channels 12, the second flow channels 12 are arranged in a circumferential array around the rotating shaft 2 inside the tool shank 1, which can make the cooling water more evenly distributed when spraying from the second flow channel 12 to the cutting member 3, achieving uniform heat dissipation for the cutting member 3. At the same time, the rotating shaft 2 can also be cooled by the water flow in the second flow channel 12.

[0035] In one embodiment, the inner diameter of the second flow channel 12 gradually decreases in the direction close to the cutting member 3.

[0036] In this embodiment, through the setting that the inner diameter of the second flow channel 12 gradually decreases in the direction close to the cutting member 3, the flow rate of the cooling water at the outlet of the second flow channel 12 can be increased, so that the cooling water forms a water mist at the outlet of the second flow channel 12. The water mist is more likely to absorb heat and evaporate, which can further improve the heat dissipation effect and at the same time reduce the consumption of cooling water.

[0037] In one embodiment, a thread 13 is provided at the position of the tool shank 1 away from the cutting member 3 corresponding to the inlet of the first flow channel 11.

[0038] In this embodiment, a thread 13 is provided at a position corresponding to the inlet of the first flow channel 11 at one end of the tool shank 1 away from the cutting member 3. The purpose is to facilitate the connection between the tool shank 1 and the pipe joint of an external water pump, so that the cooling water pumped out by the water pump can flow through the first flow channel 11 and spray out from the outlet of the second flow channel 12 to cool and dissipate heat from the cutting member 3.

[0039] In one embodiment, a knob 41 is provided at one end of the screw rod 4 away from the rotating shaft 2.

[0040] In this embodiment, by providing a knob 41 at one end of the screw rod 4 away from the rotating shaft 2, the cutting member 3 can be directly installed by twisting the knob 41 without using tools, and the operation is simple and convenient.

[0041] As Figures 4-5 shown, in one embodiment, the cutting member 3 is installed on the rotating shaft 2 through a screw rod 4. A threaded hole 21 is provided at the end of the rotating shaft 2 extending out of the tool shank 1, and a mounting hole 31 is provided at the central position of the cutting member 3. The screw rod 4 passes through the mounting hole 31 and is connected to the threaded hole 31.

[0042] In this embodiment, during assembly, the screw rod 4 is inserted into the mounting hole 31 of the cutting member 3, and then one end of the screw rod 4 passing through the cutting member 3 is aligned with the threaded hole 21 of the rotating shaft 2. The screw rod 4 is twisted so that the screw rod 4 is connected to the threaded hole 21 until the cutting member 3 is fixedly locked, and the installation is completed.

[0043] By providing the screw rod 4 and the threaded hole 21 to cooperate for installing the cutting member 3, the installation and disassembly of the cutting member 3 are convenient and fast.

[0044] In one embodiment, a washer 6 is provided between the screw rod 4 and the cutting member 3.

[0045] In this embodiment, by providing a washer 6 between the screw rod 4 and the cutting member 3, the screw rod 4 can be prevented from loosening during operation, preventing accidents. It can also disperse the force applied by the screw rod 4 to prevent the force from concentrating on one point, which helps to protect the cutting member 3 from damage.

[0046] In one embodiment, at least one limiting protrusion 5 is provided around the threaded 13 hole at the end of the rotating shaft 2. A limiting portion 32 is provided at a position corresponding to the limiting protrusion 5 on the cutting member 3, and the limiting protrusion 5 is inserted into the limiting portion 32 to limit the cutting member 3.

[0047] In this embodiment, the limiting protrusion 5 is hemispherical or columnar. Optionally, the number of the limiting protrusions 5 is two. By providing the limiting protrusion 5, when encountering a workpiece that is difficult to cut, the situation of slipping between the cutting member 3 and the rotating shaft 2 can be effectively prevented.

[0048] Among them, the limiting portion 32 is in a groove shape or a hole shape that matches the shape and size of the limiting protrusion 5.

[0049] When assembling the water-cooled saw blade of the present application, first put the washer 6 on the screw rod 4, then insert the screw rod 4 into the mounting hole 31 of the cutting member 3, and then align the end of the screw rod 4 passing through the cutting member 3 with the threaded hole 21 of the rotating shaft 2. Turn the knob 41 to connect the screw rod 4 with the threaded hole 21 until the cutting member 3 is fixedly locked. Finally, connect the threads 13 on the inner wall of the first flow channel 11 at the other end of the tool bar 1 with the threads 13 of the external water pump pipeline joint to complete the assembly.

[0050] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
