Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a disassembly device for the inner hole bearing of the continuous casting roll sleeve, which is mainly used for the automated disassembly of the inner hole bearing of the 150 bending roll sleeve in the continuous casting production line. Background Technology

[0002] The existing 150 continuous casting roll sleeve inner bore bearing is manually disassembled. The roll sleeve is manually lifted from horizontal position, moved to the disassembly workbench, placed in a special jig, and separated from the bearing at one end of the roll sleeve by 3 to 8 hammer blows with a 16-pound sledgehammer. After separation, the roll sleeve is manually removed from the disassembly workbench and placed on the ground, laid horizontally, and then the other end is lifted up and placed back on the disassembly workbench, placed in the special jig, and then separated from the bearing at the other end of the roll sleeve by 3 to 8 hammer blows with a 16-pound sledgehammer. After separation, the roll sleeve is removed from the workbench and placed horizontally on the ground. Finally, the roll sleeve is transported away by crane.

[0003] The 150 continuous casting roll has a tight fit between the inner bearing and the roll sleeve. Disassembly requires significant manual force, is cumbersome, necessitates multiple people working together, and is extremely labor-intensive, easily leading to worker fatigue and impacting work efficiency and quality. Furthermore, disassembling each roll sleeve involves multiple steps, each requiring manual handling, operation, and inspection, resulting in a lengthy process and extended maintenance cycles for the continuous casting roll, affecting production schedules. Additionally, manual operation makes it difficult to control the vertical accuracy of the roll sleeve's placement on the worktable and the jig's placement, potentially causing damage to the inner bore locating sleeve from hammer blows. Since the roll sleeve operates at 600℃, the bearing locating hole can deform, making disassembly difficult. Moreover, the disassembly process easily causes scratches and deformation on the bearing inner ring or the inner surface of the roll sleeve, affecting the assembly accuracy and service life of the bearing and roll sleeve, thus impacting the quality and stability of continuous casting production. There are also high safety risks: improper operation during manual disassembly using press equipment can easily lead to mechanical injuries and other safety accidents, threatening worker safety. Manual disassembly requires workers to possess certain skills and experience. Incorrect disassembly methods can damage roller sleeves or bearings. Therefore, workers need to be familiar with the disassembly procedures and precautions to ensure a smooth process. Manual disassembly is relatively slow and difficult to complete in a short time. This not only increases labor costs but may also affect equipment maintenance schedules and production efficiency.

[0004] Traditional manual disassembly tools have poor adaptability and are difficult to integrate with existing production processes. Traditional hammering for disassembling roller sleeve bearings can easily damage the roller sleeve, bearing, or surrounding components, especially when excessive force is applied, potentially causing cracks or deformation. The force applied by hammering is often uneven, which may lead to excessive localized stress on the bearing or roller sleeve, thus affecting its structural integrity. During hammering disassembly, it is difficult to accurately control the applied force and direction, which may result in incomplete disassembly or damage to the bearing and sleeve, affecting subsequent installation and use. Improper operation when using hammers or other tools may cause the tools to slip or bounce, causing injury to the operator. The hammering disassembly process often requires multiple attempts, is inefficient, and may require additional time for cleaning and inspection.

[0005] Therefore, when disassembling the inner bearing of the roller sleeve, adopting more scientific and safer methods, such as using specialized disassembly tools (e.g., hydraulic disassembly machines, heaters, etc.), can effectively avoid the above-mentioned drawbacks and improve the efficiency and safety of disassembly.

The roll sleeve translation device is connected to the lifting device and drives the lifting device to move laterally. The disassembly device is also installed on the main frame and is located on both sides of the roll sleeve bracket, with the disassembly device corresponding to the two support grooves on the roll sleeve bracket.

[0009] The disassembly device includes a roller sleeve clamping cylinder and a disassembly hydraulic cylinder. The disassembly hydraulic cylinder is located between the two roller sleeve clamping cylinders. The end of the roller sleeve clamping cylinder is connected to a push plate, and the piston of the disassembly hydraulic cylinder can pass through the push plate.

The roller support 10 is also provided with two grooves. The roll sleeve translation device is connected to the lifting device and drives the lifting device to move horizontally. The disassembly device is also installed on the main frame 13 and is located on both sides of the roll sleeve bracket 9. The disassembly device corresponds to the two grooves on the roll sleeve bracket 9.

[0030] See Figure 3 , Figure 4The roller sleeve translation device includes a translation cylinder 2 and a translation cylinder blocking plate 21. The piston rod of the translation cylinder 2 is connected to the translation cylinder blocking plate 21 and moves the translation cylinder blocking plate 21 laterally. A slide rail is provided on the inner wall of the translation cylinder blocking plate 21. The driving device of the lifting device is a lifting cylinder 1. The cylinder body of the lifting cylinder 1 is fixedly connected to the translation cylinder blocking plate 21. The piston rod of the lifting cylinder 1 is connected to a lifting cylinder sliding plate 22. The lifting cylinder sliding plate 22 is slidably connected to the slide rail on the inner wall of the translation cylinder blocking plate 21. Under the drive of the translation cylinder blocking plate 21, the lifting cylinder 1 moves laterally. The top of the piston rod of the lifting cylinder 1 is fixedly connected to the roller bracket 10 and drives the roller bracket 10 to move up and down.

[0031] See Figure 7 , Figure 8 The disassembly device includes a roller sleeve clamping cylinder 27 and a disassembly hydraulic cylinder 26. The disassembly hydraulic cylinder 26 is located between the two roller sleeve clamping cylinders 27. The end of the roller sleeve clamping cylinder 27 is connected to a push plate 24. The piston of the disassembly hydraulic cylinder 26 can pass through the push plate 24.

[0032] There are 8 sets of roller sleeve clamping cylinders 27, with 4 sets on each side of the main frame 13. A push plate 24 is connected to the end of every 2 sets of roller sleeve clamping cylinders 27. A disassembly hydraulic cylinder 26 is set on each side of the main frame 13, and the two sets of disassembly hydraulic cylinders 26 are staggered.

[0033] The cylinder bodies of the roller sleeve clamping cylinder 27 and the disassembly hydraulic cylinder 26 are fixed to the main frame 13 through the hydraulic cylinder connecting frame 23. The roller sleeve clamping cylinder 27 pushes the push plate 24, and the two push plates 24 clamp and position the roller sleeve. After the roller sleeve is positioned, the piston of the disassembly hydraulic cylinder 26 extends out and passes through the push plate 24. The hydraulic cylinder head 25 extends into the roller sleeve and pushes out one side bearing inside the roller sleeve.

[0034] See Figure 5 , Figure 6 and Figure 10 The centering device includes a centering cylinder 14, a guide rod 17, a flat head 18, a sliding centering baffle 12, a pull rod 20, and earrings 16. The centering device is positioned below the feeding slide plate 11. The guide rod 17 is located on both sides of the feeding slide plate 11. The flat head 18 is fixedly connected to the sliding centering baffle 12 and simultaneously slidably connected to the guide rod 17. The sliding centering baffle 12 is higher than the feeding slide plate 11. Two earrings 16 are symmetrically provided at the end of the piston of the centering cylinder 14. One end of the pull rod 20 is hinged to the earrings 16, and the other end of the pull rod 20 is hinged to the flat head 18. Figure 5The flat head 18 represents two extreme positions on the guide rod 17 within the piston stroke range of the centering cylinder 14. The piston of the centering cylinder 14 extends to push the flat head 18 and the sliding centering baffle 12 to open to both sides. When the roller sleeve rolls into position, the piston of the centering cylinder 14 retracts and pulls the flat head 18 and the sliding centering baffle 12 inward to clamp the roller sleeve, thus centering the roller sleeve to the working position.

[0035] The feeding slide plate 11 is inclined downwards. See Figure 1 , Figure 2 A roller conveyor dismantling frame 28 is fixed to the upper end of the main frame 13.

[0036] The bracket is a V-shaped groove.

[0037] The method of using this utility model is as follows:

[0038] See Figure 9 and Figure 7 , Figure 8 The roller sleeve is inserted into the feeding slide plate 11 and rolled to the position of roller sleeve I5. It is then clamped and centered by the centering device. After centering, the roller sleeve is lifted by the roller support bracket 10 and translated by the roller sleeve translation device, and then fed into the V-shaped groove of the roller sleeve bracket 9. The clamping cylinder 27 of the disassembly device clamps and positions roller sleeve III6 and roller sleeve IV7 via the push plate 24. After positioning, the hydraulic cylinder head 25 pushes out one bearing of roller sleeve III6, and the piston of the disassembly hydraulic cylinder 26 on the other side extends and pushes out the other bearing of roller sleeve IV7 via the hydraulic cylinder head 25. The clamping cylinder 27 retracts, and the push plate 24 returns to its original position, releasing roller sleeve III6 and roller sleeve IV7. At this time, the lifting cylinder 1 raises the roller support 10 and lifts roller sleeves III6 and IV7. The translation cylinder 2 pushes the lifting device to move them to the next station. After the roller support 10 falls, roller sleeve III6 is in the station of roller sleeve IV7. Roller sleeve IV7 rolls down the ramp at the tail of roller sleeve bracket 9 to the position of roller sleeve V8. Roller sleeve V8 can be removed. Then, the lifting device and the roller sleeve translation device move the roller sleeve at position I5 to the position of roller sleeve III6. The disassembly device is started again to push out one side of the bearing in roller sleeve I5 and the other side of the bearing in roller sleeve III6. Roller sleeve II4 enters the station of roller sleeve I5 to achieve centering.
