[0002] Steel pipe rolling is a metal processing process that involves continuous deformation and extension through a series of rolling mills (rollers) to eventually form the desired steel pipe shape and size. In the cold-rolled steel pipe process, it is necessary to clean impurities and apply lubricating oil on the steel pipe. The main purpose is to reduce the friction coefficient and rolling force during rolling, while cooling the rolls to control the roll shape, reduce or prevent the rolls from sticking to the steel, and improve the surface quality of the rolls and rolled steel pipes. However, it is difficult to adaptively clean the steel pipes before oiling and the subsequent oiling work according to the diameter of the steel pipe in the prior art, resulting in unqualified subsequent rolling quality of the steel pipe.

On the limit block 31 on the side of the ring 3, to avoid affecting the stability and strength of the extension rod 66 during rotation due to its excessive length, the extension rod 66 is installed with a gear three 661 meshing with the gear two 651, one end of the valve 65 is connected to the oil pump, and the other end of the valve 65 is provided with an oil delivery pipe 652, and the oil delivery pipe 652 is provided with branch pipes respectively connected to the nozzle 64, and the upper end of the extension rod 66 is provided with a support plate 662, and the support plate 662 is connected to one end of the pull rope 67, and the other end of the pull rope 67 passes through the vertical plate 68 on the fixed ring 3 and is connected to the lever 611, and the pull rope 67 is sleeved with a spring 671 located between the vertical plate 68 and the support plate 662.

[0024] Specific implementation and principle:

[0025] During operation, the steel pipe to be rolled is inserted into the annular frame 4, and the bend 53 on the connecting plate 52 is driven to rotate through the steel pipe, so that the cleaning brush 51 contacts the surface of the steel pipe to clean the surface impurities of the steel pipe. At the same time, the rotation of the rotating shaft 54 ​​drives the extension rod 66 to rotate, and the gear three 661 thereon drives the gear two 651 on the valve 65 to rotate, so that the valve 65 is opened, and the oil pump injects oil into the nozzle 64 through the oil main pipe 652 and the branch pipe and sprays it to the steel pipe. At the same time, the support plate 662 on the extension rod 66 pulls the lever 611 on the gear ring 61 through the pull rope 67 to rotate the gear ring 61, driving the gear one 62 to rotate, and the rack 63 drives the nozzle 64 to move up to the corresponding position through the gear one 62. After the lubricating oil is sprayed on the steel pipe, the steel pipe is processed by the rolling machine 2.

[0026] In summary, the present application drives the rotation of the cleaning brush 51 by the movement of the steel pipe to clean the impurities on the surface of the steel pipe. The staggered distribution of the cleaning brush 51 allows the cleaned impurities to fall off better. While the rotating shaft 54 ​​rotates, the valve 65 is opened to a corresponding degree to allow the lubricating oil to be sprayed onto the steel pipe. At the same time, the pull rope 67 is used to pull the gear ring 61 to rotate, so that the rack 63 drives the nozzle 64 to move upward, thereby adapting to the diameter requirement of the steel pipe. The steel pipe is then processed by the rolling machine 2. The entire device can better clean and spray the steel pipe before rolling it.
