[0057] Please refer to Figures 1 to 4 The utility model provides a preferred embodiment of a water supply knife rod with enhanced rigidity, which includes a mounting flange 10, a connecting portion 20, and a rod portion 30.

[0058] The mounting flange 10 has a first end 101, a second end 102, and a first outer diameter D1. The first end 101 and the second end 102 are located at opposite ends of the mounting flange 10. The first outer diameter D1 is the maximum outer diameter of the mounting flange 10. The mounting flange 10 may also include an annular groove 12 and at least one buckle groove 14 for connecting with the main shaft of the processing machine. The distance from the first end 101 to the second end 102 of the mounting flange 10 is defined as a first length L1.

[0059] The connecting portion 20 extends outward from the first end 101 of the mounting flange 10 and is used to connect to the spindle of the processing machine. The connecting portion 20 has a second outer diameter D2, which is the maximum outer diameter of the connecting portion 20 and is smaller than the first outer diameter D1.

[0060] The rod 30 extends outward from the second end of the mounting flange 10, and the rod 30 is used to mount a tool. The length L2 of the rod 30 is more than 4 times the first length L1, and the length L2 of the rod 30 is less than 7 times the first length L1. In a preferred embodiment of the utility model, the length L2 of the rod 30 is 5 to 5.5 times the first length L1, and the outer periphery of the rod 30 forms a curved line when viewed from the side. The rod 30 has a third outer diameter D3, a fourth outer diameter D4, and a fifth outer diameter D5, wherein the third outer diameter D3 is smaller than the first outer diameter D1 and greater than or equal to the second outer diameter D2, and the third outer diameter D3 is 0.8 to 0.9 times the first outer diameter D1.

[0061] The fourth outer diameter D4 is located at the front end of the rod 30 away from the mounting flange 10; the fourth outer diameter D4 is smaller than the third outer diameter D3, and the fourth outer diameter D4 is smaller than 0.4 times the first outer diameter D1. Preferably, the fourth outer diameter D4 is 0.25 times to 0.36 times the first outer diameter D1.

[0062] The fifth outer diameter D5 is located at a first distance L3 between the rod portion 30 and the second end 102 of the mounting flange 10 . The first distance L3 is 0.5 times the first length L1 . The fifth outer diameter D5 is 0.65 to 0.75 times the first outer diameter D1 .

[0063] More specifically, the rod portion 30 also includes a sixth outer diameter D6, and the sixth outer diameter D6 is located at a second distance L4 between the rod portion 30 and the second end 102 of the mounting flange 10, and the second distance L4 is 2.5 times the first length L1, and the sixth outer diameter D6 is 0.45 times to 0.55 times the first outer diameter D1.

[0064] More specifically, the water-supply knife rod with enhanced rigidity also includes a cooling channel 40, which can be connected to the water outlet system of the processing machine. The cooling channel 40 includes a main channel 41, at least two lateral channels 42, and at least two branch channels 43. The main channel 41 extends along the length direction of the rod portion 30; each of the lateral channels 42 is arranged at an angular interval and is located between the opposite ends of the rod portion 30, and has a distance from the front end of the rod portion 30, and each of the lateral channels 42 extends radially and is connected to the main channel 41; each of the branch channels 43 is arranged at an angular interval and extends from the front end of the rod portion 30 toward the mounting flange 10, and each of the branch channels 43 is connected to a lateral channel 42.

[0065] Preferably, the distance between the end of each branch channel 43 facing the front end of the rod portion 30 and the main channel 41 is smaller than the distance between the end of each branch channel 43 facing away from the front end of the rod portion 30 and the main channel 41, that is, each branch channel 43 is inclined relative to the main channel 41.

[0066] During operation, the cooling water entering the cooling channel 40 can enter the channel of the tool installed on the rod 30 through the main channel 41, and flow out through the channel of the tool to reduce the temperature of the tool. Part of the cooling water flows to each branch channel 43 through each lateral channel 42, and flows out from the front end of the rod 30, and flows through the tool installed on the rod 30 from the periphery, thereby improving the cooling effect.

[0067] Since the length L2 of the rod 30 is more than 4 times the first length L1, the tool can be inserted into the rod 30 for a longer distance, thereby improving the stability of the processing; at the same time, since the outer periphery of the rod 30 forms an arc when viewed from the side, and the third outer diameter D3 of the rod is 0.8 to 0.9 times the first outer diameter D1 of the mounting flange 10, and the fifth outer diameter D5 is 0.65 to 0.75 times the first outer diameter D1 of the mounting flange 10, the bending strength and rigidity of the rod 30 can be greatly improved.

[0068] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
