[0046] In the above-described scheme, the second guide rail 16 is installed on both sides of the inner wall of the second movable groove 507, and has a smooth sliding surface and precise dimensions, wherein the design of the second guide rail 16 ensures the stability and precision of the second polishing wheel bearing seat 508 during the movement, and reduces the wear and noise caused by friction and vibration; the second polishing wheel bearing seat 508 is a key component for supporting the rough polishing wheel 504, and second slide grooves 17 adapted to the second guide rail 16 are opened on both sides thereof, wherein the second slide groove 17 is tightly matched with the second guide rail 16, so that the second polishing wheel bearing seat 508 can move and position smoothly in the second movable groove 507; the design of the second slide groove 17 ensures that the second polishing wheel bearing seat 508 can slide accurately along the trajectory of the second guide rail 16 during the movement, avoiding deviation and shaking; this design not only improves the precision and efficiency of the polishing operation, but also facilitates the maintenance and maintenance of the equipment.

[0047] See also Figure 5 As an embodiment of the utility model, an asynchronous motor 18 is provided on one side of the frame 1, wherein the output end of the asynchronous motor 18 is fixedly connected to a driving taper sleeve pulley 19; the rotating shaft at one end of the fine polishing wheel 503 passes through the first polishing wheel bearing seat 506 and extends outward, wherein the top end of the rotating shaft of the fine polishing wheel 503 is fixedly connected to a driven taper sleeve pulley 20, and the driving taper sleeve pulley 19 and the driven taper sleeve pulley 20 are connected through a V-belt 21.

[0048] In the above scheme, the asynchronous motor 18 serves as the power source of the polishing equipment, and the asynchronous motor 18 is installed on one side of the frame 1; the active taper sleeve pulley 19 is fixedly connected to the output end of the asynchronous motor 18 and rotates with the rotation of the asynchronous motor 18, wherein the design of the active taper sleeve pulley 19 takes into account the matching with the V-belt 21 to ensure smooth and efficient transmission; the driven taper sleeve pulley 20 is fixedly connected to the top of the rotating shaft of the fine polishing wheel 503 and rotates with the rotation of the fine polishing wheel 503, wherein the design of the driven taper sleeve pulley 20 also takes into account the matching with the V-belt 21 to achieve effective transmission with the active taper sleeve pulley 19; the V-belt 21 serves as a transmission medium and is connected between the active taper sleeve pulley 19 and the driven taper sleeve pulley 20; the rotating shaft at one end of the fine polishing wheel 503 passes through the first polishing wheel bearing seat 506 and extends outward, and the fine polishing wheel 503 is responsible for fine polishing the surface of the mold steel to achieve the required surface finish and precision.

[0049] When the asynchronous motor 18 is started, its output end drives the active taper sleeve pulley 19 to rotate. Since the active taper sleeve pulley 19 and the V-belt 21 have good matching properties, the V-belt 21 can fit tightly on the active taper sleeve pulley 19 and rotate accordingly; as the V-belt 21 rotates, the V-belt 21 begins to contact and transmit power to the driven taper sleeve pulley 20. Since the driven taper sleeve pulley 20 is fixedly connected to the rotating shaft of the fine polishing wheel 503, the fine polishing wheel 503 also begins to rotate accordingly; in this process, the V-belt 21 plays a role in transmitting power and adjusting the transmission ratio; when the fine polishing wheel 503 starts to rotate, the fine polishing wheel 503 begins to perform fine polishing on the surface of the mold steel, and a suitable polishing wheel and polishing parameters are selected according to the requirements of the polishing process and the material characteristics of the mold steel for polishing operation; during the polishing process, it is necessary to maintain a smooth rotation of the fine polishing wheel 503 and a stable polishing pressure to ensure the consistency of the polishing quality, and it is also necessary to adjust the polishing parameters in time according to the polishing effect to achieve the best polishing effect.

[0050] See also Figure 5 As an embodiment of the utility model, a driving pulley 22 is coaxially arranged on the rotating shaft of the fine polishing wheel 503 near one end of the driven taper sleeve pulley 20, wherein the rotating shaft of one end of the rough polishing wheel 504 passes through the second polishing wheel bearing seat 508 and is fixedly connected with the driven pulley 23, and the driven pulley 23 is connected to the driving pulley 22 through a belt 24.

[0051] In the above-described solution, a driving pulley 22 is coaxially arranged on the rotating shaft of the fine polishing wheel 503 near one end of the driven cone pulley 20. This means that the driving pulley 22 and the fine polishing wheel 503 rotate coaxially, that is, their rotational speeds and directions are the same. The driving pulley 22 is designed to transmit the power of the fine polishing wheel 503 to the rough polishing wheel 504 to achieve the linkage between the two. The rotating shaft of one end of the rough polishing wheel 504 passes through the second polishing wheel bearing seat 508 and is fixedly connected with a driven pulley 23. The driven pulley 23 rotates with the rotation of the rough polishing wheel 504 and is a key component for receiving power and transmitting it to the rough polishing wheel 504. The design of the driven pulley 23 takes into account the belt 24 drive connection with the driving pulley 22 to ensure the smooth transmission of power. The driving pulley 22 and the driven pulley 23 are drive-connected by a belt 24. The belt 24, as a transmission medium, has the advantages of smooth transmission, low noise, accurate transmission ratio, etc., and can effectively transmit the power of the fine polishing wheel 503 to the rough polishing wheel 504.

[0052] When the fine polishing wheel 503 starts to rotate, the coaxially arranged driving pulley 22 also rotates accordingly. The rotation of the driving pulley 22 is transmitted to the driven pulley 23 through the belt 24, thereby driving the rough polishing wheel 504 to rotate. Since the belt 24 drive has the characteristic of flexible connection, it can absorb vibration and impact to a certain extent and protect the transmission components from damage. The fine polishing wheel 503 and the rough polishing wheel 504 rotate in their respective bearing seats and perform fine and rough polishing treatments on the surface of the die steel respectively. The linkage between the two makes the polishing operation more continuous and efficient.
