Abstract
Description
Technical Field
[0001] The present invention relates to the field of steel ball production, and in particular to a polishing production process for high-precision bearing steel balls used in the field of 5G or 6G communications. Background Art
[0002] During the manufacturing process, the steel balls used in wind turbine bearings usually need to go through several major processes such as cold heading, heat treatment, hard grinding, initial grinding, polishing, strengthening, fine grinding and cleaning. In the polishing process, due to the high labor intensity of polishing large wind turbine balls, the relatively high noise in the production environment where the equipment and personnel are located, and it is difficult to control the final quality during the production process. Since the polishing process is easy to get out of control, the steel balls are often not polished cleanly due to insufficient polishing time, or the surface of the steel balls is scratched and abraded due to too long polishing time, resulting in a large number of unqualified products in the flaw detection, but the actual steel balls themselves have no problems, that is, they are qualified products. Such a phenomenon has a certain impact on the qualification rate and production cost of the final product.
[0003] The existing polishing process usually pours steel balls into a wooden polishing barrel, and uses the rotation of the polishing barrel to drive the steel balls inside to circulate, so as to achieve the purpose of polishing through the mutual collision of the steel balls during circulation. The above-mentioned polishing method only uses the mutual collision between steel balls to achieve polishing, and its polishing effect is not very good. In order to improve the polishing effect, different numbers of iron collision blocks are installed in the polishing barrel, so that the steel balls will collide with the iron collision blocks during circulation. However, although such a method can improve the polishing effect, the improvement is relatively small. Moreover, in this method, when adding the collision blocks, the collision blocks are usually fixed in the polishing barrel by bolts. This method requires pre-drilling threaded holes in the polishing barrel. In addition, due to the installation of the collision blocks, the phenomenon of dead corner balls is more likely to occur, especially when processing smaller steel balls, dead corner balls are more likely to occur. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide a high-precision bearing steel ball polishing production process for 5G or 6G communication fields, which has good polishing effect and avoids the occurrence of dead-angle balls.
[0005] In order to solve the above technical problems, the technical solution of the present invention is: a high-precision bearing steel ball polishing production process for 5G or 6G communication field, the innovation of which is: comprising the following steps
[0006] S1 Cleaning: First, in the shutdown state, the steel balls are loaded into a dedicated cleaning device, the dedicated cleaning device comprising a pair of parallel cleaning seats, a horizontally arranged cleaning rotating rod is connected between the two cleaning seats, the cleaning rotating rod is driven to rotate by a first cleaning motor installed on the cleaning seat, a cleaning plate is fixedly connected to the cleaning rotating rod, a cleaning bucket is arranged on the cleaning plate, the cleaning bucket is driven to rotate by a second cleaning motor installed on the cleaning plate, and the cleaning bucket is a polygonal hollow bucket with an upper end open;
[0007] After the steel balls are loaded into the cleaning barrel, the first cleaning motor drives the cleaning rotating rod to rotate, thereby driving the cleaning barrel to swing, so that the angle between the cleaning barrel and the horizontal plane is between 40-50 degrees, and then the second cleaning motor drives the cleaning barrel to rotate, so that the steel balls roll in the cleaning barrel, and while rolling, a proper amount of clean water is injected into the cleaning barrel, and then 2-3kg of magnesium oxide and 2-3kg of soda ash are added, and the water, magnesium oxide and soda ash are stirred together to clean the steel balls. After cleaning for 5-10 minutes, while the cleaning barrel keeps rotating, a large amount of clean water is injected into the cleaning barrel to flush out the turbidity in the cleaning barrel. If there are still abrasives and stains on the surface of the steel balls, continue to clean until there are no abrasives and stains on the surface of the steel balls, then the cleaning barrel can be stopped from rotating, and the steel balls in the cleaning barrel can be unloaded into a special turnover box;
[0008] S2 Scalding: Use a sodium oleate soap aqueous solution with a mass concentration of 10% as the scalding solution to ensure the cleanliness of the sodium oleate soap aqueous solution. The sodium oleate soap aqueous solution is milky yellow. Heat the sodium oleate soap aqueous solution to 80-100°C, then hang a special turnover box with steel balls into the sodium oleate soap aqueous solution to immerse it completely. Soak for 2-4 minutes for scalding treatment, then hang it out and dry it;
[0009] S3 Polishing: Clean and inspect the dedicated polishing equipment to ensure that it is clean, free of dirt, retained balls, and debris. The dedicated polishing equipment includes a polishing bracket, on which a horizontally arranged iron polishing barrel is installed. Both sides of the iron polishing barrel are installed on the polishing bracket through the cooperation of bearings and bearing seats. The iron polishing barrel is a polygonal hollow barrel with a feed inlet on the side wall of the iron polishing barrel and a barrel cover covering the feed inlet;
[0010] Put the cloth strips into the iron polishing barrel and spread them out appropriately, then put the steel balls boiled in sodium oleate soap water solution into the iron polishing barrel, close the barrel cover, turn on the second polishing motor to drive the iron polishing barrel to polish and dry the steel balls. The polishing time is between 8-10 minutes. After drying, the surface of the steel balls must be bright, without fog and dirt. Stop the iron polishing barrel, open the barrel cover, slowly pour the steel balls into the screening table, separate the cloth strips, and all the steel balls fall into the clean special turnover box;
[0011] S4 Inspection: Check to ensure that there are no dead corners in the iron polishing barrel and on the screening table. The polished steel balls must have a bright, clean surface without fog and dirt.
[0012] Furthermore, in steps S1, S2, and S3, the special turnover box includes nylon side panels, nylon baffles, and a nylon bottom panel. There are four nylon side panels in total, which together constitute a nylon box body. A rectangular ball outlet is opened at the bottom center of one of the nylon side panels. The nylon bottom panel gradually inclines from the end away from the ball outlet to the direction of the ball outlet. Several oil outlet grooves are evenly distributed on the nylon bottom panel. The oil outlet grooves gradually extend to the ball outlet along the inclination direction of the nylon bottom panel. A nylon baffle is arranged on the inner wall of the nylon side panel with the ball outlet. The nylon side panels and the nylon bottom panel together constitute a transport box body.
[0013] Furthermore, a handle is installed on the outer side of the upper end of the nylon box. There are two handles in total, which are respectively located on both sides of the nylon box. Both ends of the handle are fixed to the nylon box by nuts, and the handle is in a C shape.
[0014] Furthermore, the diameter of the oil outlet groove gradually increases from the end away from the ball outlet to the ball outlet.
[0015] Furthermore, the nylon baffle is composed of a fixed plate and a movable plate. The cross section of the fixed plate is L-shaped. There are two fixed plates, which are relatively fixed on both sides of the upper end of the nylon side plate. Step surfaces matching the fixed plates are respectively provided at both ends of the movable plate.
[0016] Furthermore, in step S2, the sodium oleate soap aqueous solution is replaced every 10 days of use and recorded.
[0017] The advantages of the present invention are as follows: the polishing process of the present invention, through the cooperation of special cleaning equipment and special polishing equipment, combined with the design of parameters such as cleaning time, scalding temperature, polishing time, etc., can more fully clean the surface of the steel ball before polishing, so that the polishing effect is better during polishing, and the polishing effect is not affected by the attached dirt. In addition, a polygonal iron polishing barrel is used for polishing. When the steel ball circulates, it directly collides with the inner wall of the polishing barrel, and there is no need to install a collision block. On the basis of further improving the polishing effect, the phenomenon of dead corner balls is avoided.
[0018] For the design of special turnover box, the whole turnover box is made of nylon material, which can protect the steel balls very well; the bottom of the nylon box is tilted to facilitate the removal of balls and avoid the phenomenon of ball storage; by setting the oil outlet, the detergent, oil and other liquids carried by the steel balls themselves can be easily discharged after accumulating in the box.

[0025] The following embodiments can enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.
[0026] The polishing production process of high-precision bearing steel balls for 5G or 6G communication fields of the present invention comprises the following steps
[0027] The first step is cleaning: First, in the shutdown state, put the steel balls into a special cleaning equipment.
[0028] like Figure 1As shown in the schematic diagram, the dedicated cleaning device includes a pair of cleaning seats 11 arranged in parallel, a horizontally arranged cleaning rotating rod 12 is connected between the two cleaning seats 11, both sides of the cleaning rotating rod 12 are installed on the cleaning seats 11 through the cooperation of bearings and bearing seats, thereby realizing the rolling cooperation between the cleaning rotating rod 12 and the cleaning seats 11, the cleaning rotating rod 12 is driven to rotate by a first cleaning motor installed on one of the cleaning seats 11, and a cleaning plate 13 is fixedly connected to the cleaning rotating rod 12, and the cleaning plate 13 is welded and fixed to the cleaning rotating rod 12, and as The cleaning rotating rod 12 rotates and swings, a cleaning bucket 14 is arranged on the cleaning plate 13, and a plane bearing is also arranged between the cleaning bucket 14 and the upper end surface of the cleaning plate 13, thereby ensuring that the cleaning bucket 14 can rotate stably. The cleaning bucket 14 is driven to rotate by a second cleaning motor 15 installed on the cleaning plate 13. The cleaning bucket 14 is a polygonal hollow bucket with an open upper end. When this cleaning bucket 14 is used, when cleaning, the steel ball circulates inside the cleaning bucket 14, so that the steel ball can collide with the inner wall of the cleaning bucket 14, making it easier for dirt attached to the surface of the steel ball to fall off.
[0029] After the steel balls are loaded into the cleaning barrel 14, the first cleaning motor drives the cleaning rotating rod 12 to rotate, and the rotation of the cleaning rotating rod 12 drives the cleaning barrel 14 to swing, so that the cleaning barrel 14 changes from a vertical direction to an inclined direction, and the angle between the cleaning barrel 14 and the horizontal plane is between 40-50 degrees. The design of such an angle is to ensure that the steel balls can flow smoothly inside the cleaning barrel 14 without falling out, and the cleaning solution in the cleaning barrel 14 can be replaced under the condition that the cleaning barrel 14 does not stop rotating. Then, the second cleaning motor 15 drives the cleaning barrel 14 to rotate, so that The steel ball is rolled in the cleaning barrel 14, and an appropriate amount of clean water is injected into the cleaning barrel 14 while the steel ball is rolling, and then 2-3 kg of magnesium oxide and 2-3 kg of soda ash are added, and the water, magnesium oxide and soda ash are stirred together to clean the steel ball. After cleaning for 5-10 minutes, while the cleaning barrel 14 keeps rotating, a large amount of clean water is injected into the cleaning barrel 14 to flush out the turbidity in the cleaning barrel 14. If there are still abrasives and stains on the surface of the steel ball, continue to clean until there are no abrasives and stains on the surface of the steel ball, then stop the cleaning barrel 14 and unload the steel balls in the cleaning barrel 14 into a special turnover box.
[0030] like Figure 2-Figure 4 As can be seen from the schematic diagram, the special turnover box includes a nylon side panel 1, a nylon baffle and a nylon bottom panel 3.
[0031] There are four nylon side panels 1, which together form a nylon box. A rectangular ball outlet 7 is opened at the bottom center of one of the nylon side panels 1. The nylon bottom panel 3 gradually tilts from the end away from the ball outlet 7 to the ball outlet 7. Several oil outlet grooves 2 are evenly distributed on the nylon bottom panel 3. The oil outlet grooves 2 gradually extend to the ball outlet 7 along the tilt direction of the nylon bottom panel 3. A nylon baffle is set on the inner wall of the nylon side panel 1 with the ball outlet 7. The nylon side panel 1 and the nylon bottom panel 3 together form a transport box. In this embodiment, the diameter of the oil outlet groove 2 gradually increases from the end away from the ball outlet 7 to the ball outlet.
[0032] The nylon baffle is composed of a fixed plate 5 and a movable plate 4. The cross section of the fixed plate 5 is L-shaped. There are two fixed plates 5, which are relatively fixed on both sides of the upper end of the nylon side plate 1. Step surfaces matching the fixed plates 5 are respectively provided at both ends of the movable plate 4.
[0033] A handle 6 is installed on the outer side of the upper end of the nylon box. There are two handles 6, which are respectively located on both sides of the nylon box. Both ends of the handle 6 are fixed to the nylon box by nuts, and the handle 6 is in a C shape.
[0034] The second step is blanching: select a sodium oleate soap aqueous solution with a mass concentration of 10% as the blanching solution to ensure the cleanliness of the sodium oleate soap aqueous solution. The sodium oleate soap aqueous solution is milky yellow. Heat the sodium oleate soap aqueous solution to 80-100°C, and then hang a special turnover box containing steel balls into the sodium oleate soap aqueous solution so that it is completely immersed in it. Soak for 2-4 minutes for blanching treatment, and then hang it out and dry.
[0035] In the above steps, the sodium oleate soap aqueous solution is replaced every 10 days of use and recorded, so as to ensure that the sodium oleate soap aqueous solution can effectively scald the steel balls and ensure the scalding effect.
[0036] The third step is polishing: clean and inspect the dedicated polishing equipment to ensure that it is clean, free of dirt, retained balls, and debris.
[0037] like Figure 5As can be seen from the schematic diagram shown, the dedicated polishing equipment includes a polishing bracket 21, which is a rectangular frame structure composed of a plurality of horizontal bars, vertical bars and longitudinal bars. A horizontally arranged iron polishing barrel 22 is installed on the polishing bracket 21. Both sides of the iron polishing barrel 22 are installed on the polishing bracket 21 through the cooperation of bearings and bearing seats 25. The bearing seats 25 are fixed to the polishing bracket 21 by bolts. There is also a horizontally outwardly extending rotating shaft 26 on both sides of the iron polishing barrel 22. The bearings are fixed on the outer wall of the rotating shaft 26. The iron polishing barrel 22 is driven to rotate by a polishing motor installed on the polishing bracket 21. The iron polishing barrel 22 is a polygonal hollow barrel. A feed port 23 is opened on the side wall of the iron polishing barrel 22. At the same time, a barrel cover 24 covering the feed port 23 is provided on the iron polishing barrel 22. One side of the barrel cover 24 is hinged to the iron polishing barrel 22, and the other side of the barrel cover 24 is locked with the iron polishing barrel 22 by a quick wrench.
[0038] First, release the lock of the quick wrench, open the barrel cover 24, then put the cloth strips into the iron polishing barrel 24 and spread them out appropriately, then put the steel balls boiled in the sodium oleate soap aqueous solution into the iron polishing barrel 24, close the barrel cover 24, and lock it with the quick wrench, turn on the polishing motor to drive the iron polishing barrel 24 to rotate, so as to achieve polishing and drying of the steel balls. The polishing time is between 8-10 minutes. After drying, the surface of the steel balls must be bright, without fog and dirt. If the steel balls do not meet the above requirements after one polishing, they can be polished for the second time until they meet the above requirements. After drying, the iron polishing barrel 24 stops rotating, releases the lock of the quick wrench again, opens the barrel cover 24, and slowly pours the steel balls onto the screening table. The steel balls and cloth strips are manually screened to separate the cloth strips from the steel balls, and then all the steel balls fall into a clean special turnover box.
[0039] The fourth step is to check: check to ensure that there are no dead corner balls in the iron polishing barrel 24 and on the screening table. The polished steel balls must ensure that the surface is bright, clean, without fog and dirt, and the polishing of a batch of steel balls is completed.
[0040] The polishing process of the present invention, through the cooperation of special cleaning equipment and special polishing equipment, combined with the design of parameters such as cleaning time, scalding temperature, polishing time, etc., can more fully clean the surface of the steel ball before polishing, so that the polishing effect is better during polishing, and the polishing effect is not affected by the attached dirt. In addition, a polygonal iron polishing barrel is used for polishing. When the steel ball circulates, it directly collides with the inner wall of the polishing barrel, and there is no need to install a collision block. On the basis of further improving the polishing effect, the phenomenon of dead corner balls is avoided.
[0041] Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
