[0023] like Figures 1 to 5 As shown, a single-edged forming knife with a dynamic balancing groove comprises a knife handle 1, a coolant hole 2 is provided inside the knife handle 1, one end of the coolant hole 2 is connected to an infusion groove 3, a rotating rod 5 is provided at one end of the infusion groove 3, a connecting rod 7 is fixed to one end of the rotating rod 5, an infusion hole 6 is provided on the outer side of one end of the rotating rod 5, four infusion holes 6 are provided inside the rotating rod 5, and the infusion hole 6 penetrates the rotating rod 5 and is connected to the infusion groove 3, so as to facilitate the coolant to be input into the infusion hole 6 through the coolant hole 2 and the infusion groove 3;

[0024] A swivel 20 is provided on the outer wall of the swivel rod 5, and blocks 21 are fixed on both sides of the swivel 20. A slot 4 is provided on the outer wall of the block 21. A swivel plate 22 is fixed inside the swivel 20. An infusion hole three 25 is provided on the outer surface of the swivel plate 22. One side of the infusion hole three 25 is connected to the infusion hole two 8, one end of the infusion hole two 8 is connected to the infusion groove two 9, and one end of the infusion groove two 9 is connected to the liquid channel one 10. By rotating the swivel 20, it is convenient to connect and seal the infusion hole one 6 and the infusion hole two 8. When the single-edged forming knife is used, it is convenient to allow the coolant to flow into the infusion groove two 9 through the connection of the infusion hole one 6, the infusion hole three 25, and the infusion hole two 8, and then input it into the cooling hole one 13 and the cooling hole two 14 through the infusion groove two 9 and the three liquid channels to cool the cutting edge 17 and the polishing edge 18. Embodiment 2

[0025] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0026] Liquid channel 1 10 is connected to liquid channel 2 11 on both sides, and liquid channel 3 16 is provided on one side of liquid channel 2 11. The coolant in liquid channel 1 10 can flow to cooling hole 2 14 and cooling hole 1 13 respectively through liquid channel 2 11 and liquid channel 3 16, thereby reducing the temperature of cutting edge 17 and polishing edge 18 and extending the service life of the single-edged forming knife.

[0027] One end of the liquid channel three 16 is connected to the cooling hole one 13, and one end of the liquid channel two 11 is connected to the cooling hole two 14. The cooling hole one 13 and the cooling hole two 14 facilitate cooling of the cutting edge 17 and the polishing edge 18.

[0028] The rotating ring 20 forms a rotating structure with the rotating rod 5 through the clamping block 21 and the clamping slot 4, and the infusion hole 1 6 forms a connecting structure with the infusion hole 2 8 through the infusion hole 3 25. By rotating the rotating ring 20, the rotating plate 22 is driven to rotate, so that the rotating plate 22 can connect and seal the infusion hole 1 6 and the infusion hole 2 8. When the single-edged forming knife is in use, the coolant can flow into the cooling hole on the cutter head 12 through its structure, so as to cool the cutter head 12, the cutting edge 17 and the polishing edge 18, prevent the cutting edge 17 and the polishing edge 18 from being quickly worn due to excessive temperature, and extend the service life of the single-edged forming knife. In addition, the chip groove 2 and the dynamic balancing groove 1 15 are symmetrically arranged, so as to maintain the stability of the single-edged forming knife when the single-edged forming knife is in use.

[0029] A rubber pad 23 is bonded to one side of the rotating plate 22, and a rubber pad 24 is bonded to the inner wall of the rotating plate 22. The rubber pad 23 and the rubber pad 24 can increase the friction between the rotating ring 20 and the rotating rod 5 and the connecting rod 7 to prevent the rotating ring 20 from rotating without contact.

[0030] A cutter head 12 is fixed to one end of the tool handle 1, a chip groove 2 is provided on one side of the cutter head 12, a dynamic balancing groove 15 is provided on the other side of the cutter head 12, a cutting edge 17 is provided on one side of the dynamic balancing groove 15, and the chip groove 2 and the dynamic balancing groove 15 are symmetrical to each other. The symmetrical arrangement of the chip groove 2 and the dynamic balancing groove 15 facilitates the smooth operation of the single-edged forming knife when the single-edged forming knife is in use, and the chip groove 2 can discharge the chips cut by the cutting edge 17.

[0031] The outer wall of the cutter head 12 is provided with a polishing edge 18, and a chip removal groove 19 is provided on one side of the polishing edge 18. The polishing edge 18 facilitates polishing of the cut workpiece to make the machined surface smooth.

[0032] Working principle: before using the single-edged forming knife, the rotating ring 20 on the handle 1 rotating rod 5 and the connecting rod 7 is rotated through the clamping block 21 and the clamping slot 4, and the rotating ring 20 drives the rotating plate 22 to rotate, so that the infusion hole 3 25 corresponds to the infusion hole 2 8 and the infusion hole 1 6, so that the coolant enters the infusion groove 1 3 from the coolant hole 2, and then the coolant is input into the infusion groove 2 9 through the infusion hole 1 6, the infusion hole 3 25, and the infusion hole 2 8. When the rotating ring 20 is rotated, the friction between the rotating ring 20 and the connecting rod 7 and the rotating rod 5 is increased through the rubber pad 1 23 and the rubber pad 2 24 to prevent the rotating rod 5 from rotating on the outside of the connecting rod 7 and the rotating rod 5. At the same time, it can also play a sealing role to prevent the coolant from entering the gap between the infusion hole 1 6, the infusion hole 3 25, and the infusion hole 2 8. The coolant flows out, causing a waste of coolant, and the infusion hole 1 6 and the infusion hole 2 8 can be sealed at any time through the rotating ring 20. After the coolant flows into the infusion groove 2 9, it flows into the liquid channel 2 11 and the liquid channel 3 16 respectively through the liquid channel 1 10, so that the coolant flows out of the cooling hole 13 and the cooling hole 2 14 to cool the cutting edge 17 on one side of the dynamic balancing groove 15 and the chip groove 2 and the polishing edge 18 on the outer wall of the tool head 12, thereby extending the service life of the single-edged forming knife and preventing the single-edged forming knife from processing the workpiece for a long time. The temperature of the cutting edge 17 and the polishing edge 18 is too high, causing the cutting edge 17 and the polishing edge 18 to be damaged, resulting in a shortened service life, and the chips processed by the cutting edge 17 and the polishing edge 18 can be discharged through the chip groove 2 and the chip groove 1 19.
