In this process, not only the defects on the surface of cutting edge need to be removed, but also the geometric accuracy of cutting edge needs to be maintained to ensure its cutting performance. However, during polishing, a large amount of heat is generated due to the friction between the high-speed rotating grinding wheel and the surface of tungsten steel small round knife. If this heat is not dissipated in time, it is easy to cause the small round knife to deform due to heat, and even affect the hardness and wear resistance of the cutting edge. Therefore, effective heat dissipation and cooling of the surface of the small round knife become a technical problem that must be solved in the polishing process.

[0030] Water guide boss 15: designed in a conical shape, located at the top center of the polishing table 1. Its top is provided with an annular pipeline 4, which provides support for the spraying of cooling water.

Specifically, the polishing machine 3 is connected at the top of the polishing table 1 through the lifting module 2, and the driving motor drives the bearing disc 6 to rotate. In use, the lifting module 2 can adjust the height of the polishing machine 3 to adapt to the polishing requirements of small round knives 7 of different heights, and at the same time, the driving motor drives the bearing disc 6 and the small round knife 7 to rotate, forming relative motion with the polishing machine 3, and realizing comprehensive polishing of the small round knife 7.

This design improves the polishing stability of the small round knife 7 and the drainage efficiency of the bearing disc 6, and achieves the effect of improving the polishing precision and keeping the working environment dry.
[0042] Example three
[0043] Please refer to Figures 1-5As shown, the bottom of the polishing table 1 is provided with a collecting box 8 on both sides, the top of the collecting box 8 is provided with a communication channel 16 communicated with the drain port 12, specifically, through the communication channel 16 communicated between the collecting box 8 and the drain port 12, in use, the wastewater and debris generated during polishing flow into the communication channel 16 through the drain port 12, and finally into the collecting box 8, realizing effective collection and treatment of wastewater and debris.

[0044] The two sides of the annular pipeline 4 are connected with the protective fence 5 through the connecting sleeve 11, and one side of the annular pipeline 4 is communicated with the communication pipe 9.

This design improves the smoothness of the drain port 12 and the safety of the operation process, achieving the effects of enhancing the stability of the equipment and protecting the safety of the operator.
[0046] The scheme has the following working process:
[0047] When using the tungsten steel small round knife polishing device with heat dissipation function, first, adjust the polishing machine 3 to the appropriate height through the lifting module 2 to adapt to the size of the tungsten steel small round knife 7 to be polished. Then, connect the small round knife 7 with the screw hole at the top center of the bearing disc 6 through the screw rod of the positioning clamp 14, to ensure that the small round knife 7 is stably installed on the bearing disc 6. At this time, the bearing disc 6 is located at the top center of the water guide boss 15 and is surrounded by the annular pipeline 4. The annular pipeline 4 is stably connected with the protective fence 5 through the connecting sleeve 11, and the inner ring is communicated with several nozzles 10, which are uniformly distributed and ready for spraying heat dissipation.
[0048] After starting the grinding machine 3, the grinding machine 3 starts to grind the small circular knife 7. At the same time, the driving motor drives the bearing disc 6 and the small circular knife 7 to rotate through the shaft sleeve, and forms relative motion with the grinding machine 3 to realize overall grinding. In this process, the communication pipe 9 on one side of the annular pipeline 4 injects cooling water into the annular pipeline 4, and the cooling water is sprayed out through the spray head 10 to form fine water mist, which uniformly covers the surface of the small circular knife 7 and effectively absorbs and carries away the heat generated during grinding.
[0049] Due to the design of the water guide boss 15 as a cone, the water mist and the waste water generated during grinding are gathered downward under the action of gravity, and are further guided through the drainage groove 17 at the top edge of the bearing disc 6, and finally discharged through the liquid discharge port 12 opened on both sides of the top of the grinding table 1. The filter plate 13 fixedly connected inside the liquid discharge port 12 filters out the debris and impurities in the waste water, avoids clogging the liquid discharge port 12, and at the same time ensures that the waste water flows smoothly into the communication channel 16 and finally into the collection box 8, realizing effective collection and treatment of the waste water and debris.
[0050] The protective fence 5 plays a protective role during the entire grinding process, preventing debris and water splashes generated during grinding from splashing, and ensuring the safety and cleanliness of the working environment. In addition, the size of the bearing disc 6 is larger than the size of the small circular knife 7, which ensures that the small circular knife 7 will not exceed the range of the bearing disc 6 during grinding, further improving the safety of the operation.
