Description

Technical Field

[0001] This utility model belongs to the technical field of crystallizer copper tube processing equipment, specifically relating to a cleaning and polishing device for crystallizer copper tube processing. Background Technology

[0002] The crystallizer copper tube is an accessory used in continuous casting machines for cast steel. It is a core component of the continuous casting machine, responsible for the solidification and forming of molten steel. Its structure, material, and performance parameters play a decisive role in the quality of the cast billet and the production capacity of the casting machine. During the production process, the inner wall of the crystallizer copper tube needs to be polished to remove the burrs.

[0003] Existing polishing equipment generally requires clamping copper tubes sequentially onto fixtures, allowing polishing of only one copper tube's inner wall at a time. This affects polishing efficiency and results in poor polishing effects, failing to effectively polish and clean the corners of the copper tube's inner wall. Furthermore, when polishing the inner wall of the copper tube, polishing debris accumulates inside the tube's cavity, making it difficult to remove and thus hindering the cleaning of the tube's interior. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a cleaning and polishing device for processing copper tubes in crystallizers. This device allows an electric push rod to drive a polishing mechanism to effectively polish all parts of the inner wall of the copper tube, including corners, greatly improving the polishing effect. The first and second lateral moving mechanisms enable the polishing mechanism to move quickly above the corresponding copper tube, effectively increasing polishing efficiency. The blowing structure provides high-pressure airflow to the polished areas, effectively cleaning metal debris adsorbed inside the copper tube. This makes the device more suitable for polishing and cleaning the inside of copper tubes.

The second lead screw is connected to the drive shaft of the second motor. The slide rod is arranged parallel to the second lead screw. There are two limit rods, which are respectively arranged below the second lead screw and the slide rod and are parallel to each other. The lateral movable plate is threaded to the outside of the second lead screw and sleeved on the outside of the slide rod and the limit rod.

[0021] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 6 The embodiments are described in detail below.

[0022] This embodiment provides a cleaning and polishing device for processing copper tubes in crystallizers, as shown in the attached document. Figure 1-6As shown, the device includes a placement rack 1 for placing copper tubes and a top support rack 2. A rectangular limiting frame 3 for vertically placing copper tubes is fixedly connected to the upper surface of the bottom of the placement rack 1. Several rectangular limiting frames 3 are fixedly connected to the upper surface of the bottom of the placement rack 1 in a rectangular array. The top support rack 2 is fixedly connected to the upper surface of the placement rack 1, and a first lateral moving mechanism is provided at its top. The first lateral moving mechanism includes a first motor 4, a first lead screw 5, a lead screw slide 6, and a top bracket 7. There are two first lead screws 5, which are rotatably connected to both sides of the upper surface of the top support rack 2 and arranged parallel to each other. The first motor 4 is fixedly installed on the upper surface of the top support rack 2, and its output shaft is connected to it via a spline. One end of the first lead screw 5 is connected to a gear shaft 8, and the ends of the two first lead screws 5 away from the first motor 4 are fixedly connected to the gear shafts 8. The two gear shafts 8 are externally connected to a belt 9. The two sides of the lower surface of the top bracket 7 are fixedly connected to lead screw slides 6, and the two lead screw slides 6 are connected to the outside of the first lead screw 5 by threaded transmission. There are two top brackets 7, and the two top brackets 7 are respectively connected to the outside of the two first lead screws 5 by lead screw slides 6. When the first motor 4 drives the corresponding first lead screw 5 to rotate, it can drive the other first lead screw 5 to rotate synchronously through the belt 9, so that the two first lead screws 5 drive the two top brackets 7 to move laterally synchronously, so as to achieve the purpose of adjusting the structure above the top bracket 7 to move along the axial direction of the first lead screw 5.

[0023] A second lateral moving mechanism is provided between the two top supports 7. The second lateral moving mechanism includes a second motor 10, a second lead screw 11, a slide rod 12, a limit rod 13, and a lateral movable plate 14. The second lead screw 11 is rotatably connected to one side between the two top supports 7 and is connected to the drive shaft of the second motor 10 via a spline. The second motor 10 is fixedly installed on the side of one of the top supports 7. The slide rod 12 is fixedly connected to the other side between the two top supports 7 and is arranged horizontally parallel to the second lead screw 11. Limit rods 13 are provided below the second lead screw 11 and the slide rod 12, and the two limit rods 13 are respectively fixedly connected to the two sides between the two top supports 7. The lateral movable plate 14 is connected to the outside of the second lead screw 11 via a threaded drive and is sleeved on the outside of the slide rod 12 and the two limit rods 13. The lateral movable plate 14 can move along the axial direction of the slide rod 12 and the limit rod 13 under the drive of the second lead screw 11.

[0024] An electric push rod 15 is fixedly installed on the upper surface of the transverse movable plate 14, and the movable rod part of the electric push rod 15 passes through the lower part of the transverse movable plate 14. The bottom end of the movable rod of the transverse movable plate 14 is fixedly connected to a hanger 16, and a drive mechanism is provided at the bottom of the hanger 16. The drive mechanism includes a third motor 17 and an external gear ring 18. The third motor 17 is fixedly installed on the inner bottom wall of the hanger 16, and the drive shaft passes through the lower part of the hanger 16 and is connected to the external gear ring 18 through a spline.

[0025] The drive mechanism is externally connected to a polishing mechanism for polishing the inner wall of the copper tube. The polishing mechanism includes a fixed plate 19, a main polishing roller shaft 20, spur gears 21, and a secondary polishing roller shaft 22. There are two fixed plates 19, which are respectively located at the top and bottom of the main polishing roller shaft 20 and the secondary polishing roller shaft 22. The main polishing roller shaft 20 is vertically rotatably connected between the centers of the two fixed plates 19, and the end of the shaft at the top passes through the top fixed plate 19 and is fixedly connected to the center of the lower surface of the outer gear ring 18. Spur gears 21 are rotatably connected at the four corners of the upper surface of the fixed plate 19, and there are eight spur gears 21 in total. The eight spur gears 21 are evenly divided into four groups, and the four groups of spur gears 21 are rotatably connected at the four corners of the upper surface of the fixed plate 19. The two spur gears 21 in each group are meshed with each other. Furthermore, the tops of the eight spur gears 21 are rotatably connected to the bottom of the hanger 16. The bottom ends of the four spur gears 21 that are far from the outer gear ring 18 are fixedly connected to the auxiliary polishing roller shafts 22. The main polishing roller shaft 20 and the four auxiliary polishing roller shafts 22 are vertically rotatably connected between the two fixed plates 19. The four spur gears 21 that are close to the outer gear ring 18 are meshed with the outer gear ring 18. After the outer gear ring 18 rotates, it can drive the four auxiliary polishing roller shafts 22 to rotate synchronously through the spur gears 21 around it. The four auxiliary polishing roller shafts 22 are arranged in a ring array around the main polishing roller shaft 20. The distance between the outermost edges of each pair of adjacent auxiliary polishing roller shafts 22 is the same as the diameter of the main polishing roller shaft 20, which can ensure that the main polishing roller shaft 20 and the auxiliary polishing roller shafts 22 can contact the inner wall of the copper tube.

[0026] When polishing the inner wall of the copper tube, the main polishing roller 20 is mainly used to polish the inner wall of the copper tube, while the auxiliary polishing rollers 22 around the perimeter can easily polish the right-angle corners of the copper tube, thus polishing the areas that the main polishing roller 20 cannot reach. This makes it easier to fully and thoroughly polish the inner wall of the copper tube and improve the production quality of the copper tube.

[0027] The top of the hanger 16 is equipped with an air-blowing structure for cleaning residue and metal debris from the inner wall of the copper tube. The air-blowing structure includes a high-pressure blower 23, a diverter pipe 24, and guide pipes 25. The high-pressure blower 23 is fixedly installed on the upper surface of the hanger 16, and its outlet end is connected to the inlet end of the diverter pipe 24. There are four guide pipes 25 arranged in a rectangular array around the top of the hanger 16. The outlet ends of the diverter pipes 24 are all connected to the four guide pipes 25. The air outlet at the bottom of the tube 25 is tilted away from the axis of the main polishing roller 20. When the polishing mechanism polishes the inner wall of the copper tube, the high-pressure blower 23 blows air into the guide tube 25 through the diversion tube 24. The air is guided by the guide tube 25 to the polishing part of the polishing mechanism and the copper tube, thereby blowing away the metal debris generated after polishing and effectively cleaning the inner wall of the copper tube. The synchronous movement of the blowing structure and the polishing mechanism facilitates the overall cleaning of the inner wall of the copper tube.

[0028] In summary, the cleaning and polishing device for processing copper tubes in crystallizers has the following operating steps:

[0029] 1. Place the copper tube to be processed vertically inside the rectangular limiting frame 3 of the placement rack 1 to ensure that the copper tube is vertical and stable;

[0030] 2. Start the first motor 4 of the first transverse drive mechanism, drive the two first lead screws 5 to rotate synchronously through the belt 9, drive the two top supports 7 to move laterally along the axis of the first lead screws 5, so that the second transverse moving mechanism is aligned with the direction of the copper tube axis.

[0031] 3. Start the second motor 10 of the second transverse moving mechanism, drive the second lead screw 11 to rotate, and drive the transverse movable plate 14 to move longitudinally along the slide bar 12 and the limit bar 13, so as to move the polishing mechanism directly above the copper tube.

[0032] 4. Control the electric push rod 15 to extend the movable rod downward, driving the hanger 16 and the polishing mechanism at the bottom to descend, so that the main polishing roller shaft 20 and the auxiliary polishing roller shaft 22 enter the inner wall of the copper tube. Adjust the extension stroke of the electric push rod 15 according to the length of the copper tube to ensure that the polishing mechanism covers the area to be processed inside the copper tube.

[0033] 5. Start the third motor 17 of the drive mechanism to drive the external gear ring 18 to rotate. The external gear ring 18 drives the main polishing roller shaft 20 and the four auxiliary polishing roller shafts 22 to rotate synchronously through the meshing spur gear 21. The main polishing roller shaft 20 polishes the straight wall area of ​​the copper tube, and the auxiliary polishing roller shafts 22 polish the right-angle corner area.

[0034] 6. Synchronously control the first transverse drive mechanism and the second transverse moving mechanism to make the polishing mechanism move along the axial and radial directions of the copper tube to complete the full polishing of the inner wall;

[0035] 7. Start the high-pressure blower 23. The airflow is distributed to the four guide pipes 25 through the diverter pipe 24. The inclined air outlet of the guide pipe 25 blows the airflow toward the polishing area to remove metal debris generated during polishing in real time. When the polishing mechanism moves, the air blowing structure follows synchronously to ensure that the inner wall of the copper pipe is clean throughout the process.

[0036] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
