Description

Technical Field

[0001] This utility model relates to the technical field of crystallizer copper tube polishing equipment, and in particular to a pneumatic polishing machine for polishing crystallizer copper tubes. Background Technology

[0002] The length of the crystallizer copper tube is generally 900~1000mm. The inner cavity of the crystallizer copper tube can be square, round, or irregularly shaped. The smoother the inner surface of the crystallizer copper tube, the better the adhesion of the plating layer and the higher the steel throughput. However, traditional crystallizer copper tubes are polished using mechanical belt polishing machines. These machines are not only bulky, but the roughness of the crystallizer copper tubes polished by them can only reach 0.016~0.032mm. In addition, some areas of the crystallizer copper tube polished by mechanical belt polishing machines still need to be manually processed, which is inefficient and cannot meet the current market needs.

The second bevel gear 14 is coaxially fixedly installed on the rotor long shaft 9 and rotatably installed in the steering housing. The first bevel gear 13 is coaxially fixedly installed on the central shaft 12 and meshes with the second bevel gear 14. The third end cover 17 is installed on the end of the steering housing away from the second bearing 10 to prevent the rotating shaft from falling off. The polishing assembly is detachably installed on the connecting rod 18 by threads. The connecting rod 18 is detachably installed on the lower shaft 15 by threads.

[0032] The polishing assembly includes a support sleeve 19, a grinding disc 20, and a polishing pad 21. The support sleeve 19 is detachably mounted on the connecting rod 18 by threads. The grinding disc 20 is fixedly mounted on the support sleeve 19, and the polishing pad 21 is bonded to the lower end of the grinding disc 20.

[0034] The working principle of this utility model is as follows: Install air inlet connector 1 on the operating table with air inlet channel, and connect the air duct 2 on air inlet connector 1 to the air inlet channel on the operating table. The air inlet channel on the operating table is connected to the external blower through the hydraulic station pipeline.

[0035] Example 1: When polishing the square crystallizer copper tube, insert the grinding disc 20 and polishing pad 21 into the crystallizer copper tube, start the blowing device, and the blowing device will blow air through the hydraulic station pipe and the air inlet pipe into the air duct 2 on the air inlet connector 1, through the air duct 3 and the air duct 1 into the air inlet hole 30, the air inlet chamber 23, and the air inlet slot 24. The air will drive the rotor 7 to rotate by blowing the fan blades 29. When rotating, the fan blades 29 move along the inner wall of the eccentric chamber in the cylinder 6, following the center of the rotor 7. As the distance to the inner wall of the eccentric chamber gradually decreases, the fan blade 29 gradually slides in the guide groove on the rotor 7. When the rotor 7 rotates, it drives the second bevel gear 14 to rotate through the rotor long shaft 9. The second bevel gear 14 drives the central shaft 12 to rotate through the first bevel gear 13. The central shaft 12 drives the upper shaft 11 and the lower shaft 15 to rotate. The lower shaft 15 drives the support sleeve 19 to rotate through the connecting rod 18. The support sleeve 19 drives the polishing disc 21 to rotate through the grinding disc 20, thereby polishing the inner wall of the copper tube of the crystallizer.

[0036] Example 2: When it is necessary to polish the copper tube of the circular crystallizer, replace the first grinding disc 20 in the polishing assembly with the second grinding disc 31, and replace the first polishing plate 21 with the second polishing plate 32. The connection method of the second grinding disc 31 is the same as that of the first grinding disc 20, and the connection method of the second polishing plate 32 is the same as that of the first polishing plate 21. The polishing principle is the same as that of Example 1.
