Description
Technical Field
[0001] The utility model relates to the technical field of cold rolling mills, and particularly relates to a cold rolling tube mill with a surface cleaning mechanism. Background Technique
[0002] The cold rolling tube mill is a process equipment that cold-rolls a rough tube using an annular hole. This machine has good bloom-opening performance and can also roll non-ferrous metal seamless tubes with ordinary precision. The biggest feature of the cold rolling tube mill is its high material utilization rate, and its precision and surface roughness are both better than those of cold-drawn tubes. During the cold rolling process, two rolling rolls squeeze the metal tube from top to bottom. The metal tube to be rolled is mostly a blank tube, and there are residues remaining on the outer wall of the blank tube. When the two rolling rolls roll the metal tube, the extrusion force causes the metal tube to reach the required size. However, when the rolling rolls squeeze the metal tube, they also squeeze the residues, causing some residues to be squeezed and adhered to the concave surface of the rolling rolls.
[0003] After retrieval, the existing Chinese patent publication number is: CN218340645U, which provides an automatic cold rolling tube mill. This patent forms a brushing action on the concave surface of the rolling roll through a rotating brush. In this way, when the concave surface of the rolling roll adheres to residues during the cold rolling process of the blank tube, the rotation of the rotating brush can effectively clean the concave surface of the rolling roll. Therefore, it avoids the situation where residues squeeze the surface of the blank tube during the cold rolling process of the rolling roll, causing concave marks on the surface of the blank tube, resulting in defective products in the rolled metal tube, further ensuring the quality of the metal tube after cold rolling treatment. At the same time, this method also does not require workers to regularly process the concave surface of the rolling roll, further reducing the working pressure and intensity of workers, and also ensuring the personal safety of workers.
[0004] Although the above patent can effectively clean the concave surface of the rolling roll through the rotation of the rotating brush, thus avoiding the situation where residues squeeze the surface of the blank tube during the cold rolling process of the rolling roll, causing concave marks on the surface of the blank tube.

An installation groove 21 is provided on the outside of the connecting plate 20. Two springs 22 are fixedly connected in the installation groove 21. A cleaning brush plate 23 is fixedly connected to the outer end of the spring 22. A brush is provided outside the cleaning brush plate 23. The cleaning brush plate 23 can contract in the installation groove 21 due to the compression and contraction of the spring 22. A driving component is arranged on the left side of the top of the box body 1. The right side of the driving component is connected to the moving frame 3. Rolling rolls 27 are fixedly connected to the outside of both of the two rotating shafts 4.
[0034] Refer to Figure 1 , The driving component includes a support frame 24. The bottom of the support frame 24 is fixedly connected to the box body 1. A cylinder 25 is fixedly connected to the outside of the support frame 24. A connecting frame 26 is fixedly connected to the output end of the cylinder 25. The bottom of the connecting frame 26 is fixedly connected to the moving frame 3. By cooperating with the rollers 5 and the sliding grooves 2 through the driving component, the moving frame 3 can be driven to reciprocate along the sliding grooves 2.
[0035] Refer to Figure 2 , Figure 3 and Figure 5, both sides of the bottom of the moving frame 3 are fixedly connected with two rollers 5, and the rollers 5 are arranged in the sliding grooves 2. The movement of the rollers 5 in the sliding grooves 2 plays a role in limiting. The large gears 6 are arranged outside both sides of the moving frame 3, and the two large gears 6 are meshed and connected with the two racks 7. The rack plate 14 is arranged in the slot 15, and the outer part of the rack plate 14 is slidably connected with the inner wall of the slot 15, which facilitates the rack plate 14 to move in the slot 15. The small gear 17 is arranged between the two rack plates 14, and both sides of the small gear 17 are meshed and connected with the rack plates 14, playing a transmission effect. Both adjacent sides of the two fixing plates 11 are fixedly connected with motors 18, and the output ends of the motors 18 are fixedly connected with the rotating rods 16.

The cleaning brush plate 23 is arranged in the installation groove 21, and the outer part of the cleaning brush plate 23 is slidably connected with the inner wall of the installation groove 21, which facilitates the cleaning brush plate 23 to expand and contract in the installation groove 21.
[0036] Working principle: When in use, start the cylinder 25 to drive the connecting frame 26 to move, thereby pushing the moving frame 3 to reciprocate in the sliding groove 2 through the rollers 5. The reciprocating movement of the moving frame 3 drives the two large gears 6 to rotate forward and backward along the racks 7. The rotation of the two large gears 6 drives the two rotating shafts 4 to rotate, and then drives the two rollers 27 to rotate. There is a blank tube (not marked in the figure) in the shielding tube 9, and the blank tube passes through the shielding tube 9 and extends between the two rollers 27. In this way, the two rollers 27 can cold-roll the blank tube. Start the motor 18 to drive the rotating rod 16 and the small gear 17 to rotate. Through the meshing connection, it drives the two rack plates 14 to move away from or towards each other, thereby driving the two telescopic plates 13 to expand and contract in the through grooves 12, and then driving the two cleaning brush plates 23 to approach both sides of the roller 27. Cooperating with the rotating roller 27 can clean the concave surface of the roller 27. Therefore, it avoids the situation that the residue squeezes the surface of the metal tube when the roller 27 cold-rolls the metal tube, resulting in dents on the surface of the metal tube. And through the compression and contraction of the spring 22, the cleaning brush plate 23 can contract in the installation groove 21, making the brush on the cleaning brush plate 23 fit more closely with the concave surface of the roller 27, and the cleaning effect is better.
