Description

Technical Field

[0001] This invention relates to the field of hydraulic tooling technology for support roller seats, specifically to a hydraulic tooling for support roller seats and its usage method. Background Technology

[0002] Hydraulic tooling for support roll seats is a special hydraulic complete set of equipment for the grinding rolls of hot / cold rolling mills. It is used for the disassembly and assembly of support rolls (support rolls) and bearing seats (roll seats).

[0003] The hydraulic tooling for support roll seats can independently pull out / press the bearing housing from the support roll neck, and inspect the oil film bearing, slide plate, and seal. In conjunction with the hydraulic push-pull cylinder, lifting track cylinder, and balance cylinder within the mill stand, the entire set of upper and lower support rolls and roll seats can be pulled out of the frame as a whole, without the need for complete removal of the separate roll and roll seat. It can also be used with the mill stand to complete the pull-out / push-in roll replacement operation for the entire support roll system. However, in the use of hydraulic tooling for support roll seats, there are many specifications of support roll seats, and the base of the hydraulic tooling is integrally molded. This results in various support roll seats not being able to maintain coaxiality with the hydraulic system after installation, meaning the hydraulic tooling can only meet the needs of one type of support roll seat. Consequently, the hydraulic tooling cannot be matched with multiple support roll seats, requiring operators to constantly replace the hydraulic tooling. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the hydraulic tooling for the support roller seat cannot be matched with various support roller seats, and operators need to constantly change the hydraulic tooling for the support roller seat. Therefore, a hydraulic tooling for the support roller seat is proposed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: Design a hydraulic fixture for supporting a roller seat, including a base plate and a bracket. The top rear of the base plate is fixedly connected to the bottom of the bracket. The front of the bracket is machined with a groove. The top opening of the base plate is connected to a control structure. The top of the bracket is connected to a hydraulic structure. Vertical plates are respectively connected to the left and right sides of the top of the control structure.

[0006] This feature: The base plate serves to fix the position of the support and ensure its stable operation. At the same time, through structural design, it coordinates the connection between the support and other components to reduce the impact of vibration.

[0007] Preferably, the control structure includes a straight plate and a first cylinder. The outer cylindrical wall of the straight plate is threadedly connected to the top opening of the bottom plate by bolts. The front and rear sides of the top of the straight plate are respectively fixed to the bottom of the two first cylinders. The output end of the first cylinder is fixedly connected to a top plate. The outer circular opening of the top plate is threadedly connected to a beam plate by bolts.

[0008] This setting: The bolt rotates upward through the straight plate, the bottom of the bolt's outer wall disengages from the top opening of the base plate, and then the straight plate is pulled forward to disengage from the base plate.

[0009] Preferably, the rear outer wall of the beam plate is slidably connected to the inner wall of the groove.

[0010] This feature allows the beam to slide up and down through the inner wall of the groove under stress, while the groove also restricts the beam, enabling it to slide stably up and down.

[0011] Preferably, the top left and right sides of the beam plate are fixedly connected to the bottom of the two vertical plates respectively.

[0012] This feature: The beams and slabs serve to fix the position of the uprights and ensure their stable operation. At the same time, the structural design coordinates the connection between the uprights and other components to reduce the impact of vibration.

[0013] Preferably, the inner wall of the upright plate is threaded with a second screw.

[0014] This feature: The inner wall of the upright plate is threaded, and when the second screw is under force, it rotates left and right through the inner wall of the upright plate.

[0015] Preferably, a bent plate is rotatably connected to the inner side of the outer wall of the second screw.

[0016] This setting: The inner side of the outer wall of the second screw is subjected to force and rotates through the bearing in the circular opening of the outer wall of the bent plate. At the same time, when the second screw rotates left and right, it will move the bent plate left and right.

[0017] Preferably, a second handle is fixed to the outer end of the second screw, and the bottom of the bent plate is in contact with the top of the beam plate.

[0018] This feature allows the second handle to form a point of leverage with the hand; by gripping and turning the second handle, the second screw can be rotated.

[0019] Preferably, the hydraulic structure includes a second cylinder and a round rod. The bottom of the second cylinder is fixedly connected to the top of the bracket, and the output end of the second cylinder is fixedly connected to the rear end face of the round rod. Rib plates are fixedly connected to the upper and lower sides of the round rod, and a first screw is rotatably connected to the outer circular opening of the rib plate. A sliding plate is threadedly connected to the outer wall of the first screw, and a first handle is fixedly connected to the outer end of the first screw. A groove plate is fixedly connected to the front side of the round rod.

[0020] This setting: The first screw rotates through the bearing in the circular opening on the outer wall of the prism plate, and the first handle can form a force point with the hand. Turning the first handle will rotate the first screw.

[0021] Preferably, the opening on the outer wall of the groove plate is slidably connected to the outer wall of the slide plate.

[0022] This setting allows the skateboard to slide up and down through the opening on the outer wall of the groove plate when subjected to force. At the same time, the groove plate restricts the skateboard, ensuring stable linear motion.

[0023] Preferably, the rear end face of the prism is fixedly connected to the output end of the second cylinder.

[0024] This feature increases the contact surface of the prism plate, making it more stable on the outer wall of the round rod and preventing deformation.

[0025] How to use the hydraulic tooling for supporting roller seats: S1, Hydraulic fixture for supporting roller seat: Place the bottom of the support roller seat against the top of the beam plate. Then, grasp the second handle and rotate the second screw inward through the vertical plate. The rotating second screw moves the bent plate inward against the beam plate, so that the inner side of the bent plate is against the outer wall of the support roller seat. Then, make the front of the support roller seat against the inner bend of the bent plate. Then, continue to rotate the second screw to make the bent plate clamp the support roller seat. S2. Next, the first cylinder is energized, and its output end moves the top plate upwards. The moving top plate then moves the beam upwards, causing the beam to adjust its position by dragging the top support roller seat, aligning the bearing position of the support roller seat with the groove plate position. Before officially starting the roller seat disassembly and assembly operation, it is necessary to connect the tooling's hydraulic oil supply station in advance, check all hydraulic pipeline joints for leaks, and ensure that the oil pressure gauge readings are within the equipment's standard range. Simultaneously, use a wire brush and compressed air to clean the surface of the beam plate of accumulated iron oxide scale, oil stains, and metal debris to prevent the bottom of the roller seat from tilting after placement. When using a workshop overhead crane to lift the support roller seat, control the crane to lower it slowly, and prevent heavy objects from directly impacting the beam plate to avoid deformation under load.

[0026] The hydraulic tooling for a support roller seat proposed in this invention has the following advantages: by energizing the first cylinder in the control structure, the output end of the first cylinder moves the top plate upward, and the moving top plate moves the beam plate upward. At this time, the beam plate drags the top support roller seat to adjust its position, so that the bearing position of the support roller seat is aligned with the position of the groove plate. This allows the hydraulic tooling for the support roller seat to be matched with various support roller seats without the need to constantly replace the hydraulic tooling for the support roller seat.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-8 In this embodiment, a hydraulic fixture for supporting a roller seat includes a base plate 1 and a bracket 4. The top rear of the base plate 1 is fixedly connected to the bottom of the bracket 4. The function of the base plate 1 is to fix the position of the bracket 4 and ensure its stable operation. At the same time, the structural design coordinates the connection between the bracket 4 and other components to reduce the impact of vibration. The front of the bracket 4 is machined with a groove 9. The top opening of the base plate 1 is connected to a control structure 2. The top of the bracket 4 is connected to a hydraulic structure 3. The top left and right sides of the control structure 2 are respectively connected to vertical plates 5.

[0030] This embodiment uses the standard working conditions of a metallurgical grinding mill as the adaptation benchmark. The tooling is compatible with the support roller seats of hot rolling and cold rolling mills with widths of 0.8m-2.3m. The base plate 1 is made of 12mm thick Q355 low-alloy high-strength steel plate, cut and formed as a whole, with overall dimensions of 1200mm×750mm. Φ18 countersunk mounting holes are reserved at the four corners of the plate, and M16 high-strength anchor bolts are provided to lock the entire tooling to the hardened work area floor of the grinding mill. Eight transverse load-bearing reinforcing ribs are welded at equal intervals at the bottom of the base plate, each rib with a height of 40mm, which can distribute the concentrated load from the heavy roller seats. The maximum static load of the tooling can reach 12 tons, fully covering the maintenance needs of large support roller seats in wide and thick plate production lines.

[0031] The entire surface of the base plate is coated with three layers of oil-resistant and wear-resistant epoxy anti-corrosion coating, which can resist the corrosion of workshop emulsions, cooling water, and iron oxide scale for a long time, preventing the base plate from rusting, thinning, and deforming under load. The support 4 is made of 100×100mm rectangular seamless square tubes, fully welded together, with an overall height of 900mm. Two sets of triangular reinforcing ribs are welded to the back of the support to offset the reverse bending moment generated by hydraulic jacking operations, preventing the support from tilting and weld cracking due to long-term unilateral stress. The groove 9 on the front of the support is integrally milled and the inner wall of the groove is polished smooth to reduce the sliding resistance when the beam plate is raised and lowered.

[0032] Control structure 2 includes a straight plate 201 and a first cylinder 202. The outer cylindrical wall of the straight plate 201 is threadedly connected to the top opening of the base plate 1 by bolts. When the bolts are rotated upward through the straight plate 201, the bottom of the outer wall of the bolts disengages from the top opening of the base plate 1, and then the straight plate 201 is pulled forward to disengage from the base plate 1. The front and rear sides of the top of the straight plate 201 are fixedly connected to the bottom of the two first cylinders 202 respectively. The first cylinders 202 are multi-stage cylinders. The output end of the first cylinders 202 is fixedly connected to a top plate 203. The outer circular opening of the top plate 203 is threadedly connected to a beam plate 204 by bolts. The rear of the outer wall of the beam plate 204 is slidably connected to the inner wall of the groove 9. The beam plate 204 slides up and down through the inner wall of the groove 9 under force. At the same time, the groove 9 restricts the beam plate 204, allowing the beam plate 204 to slide up and down stably. The left and right sides of the top of the beam plate 204 are respectively connected to two vertical plates 5. The bottom is fixedly connected. The function of the beam plate 204 is to fix the position of the upright plate 5 and ensure its stable operation. At the same time, the structural design coordinates the connection between the upright plate and other components to reduce the impact of vibration. The straight plate 201 is made of 8mm steel plate bent into one piece. The cylindrical mounting base is symmetrically welded on both sides. The base has threaded holes and is equipped with 4 M12 high-strength anti-loosening bolts to lock and fix it to the base plate. After loosening the bolts, the straight plate and cylinder assembly can be pulled forward as a whole, which is convenient for disassembling and inspecting the lifting drive component and replacing the seals.

[0033] The two first cylinders 202 employ a synchronized hydraulic oil circuit supply, with a matching flow-dividing synchronization valve controlling the lifting stroke of both cylinders to be completely identical. The total lifting stroke of the cylinders is adjustable from 0-320mm. Small, light-duty roller seats can be placed in a low position, while large, heavy-duty roller seats can be raised for centering, adapting to the height adjustment needs of all roller seat specifications. The top plate 203 is made of 40Cr tempered heat-treated steel plate, with four sets of M10 threaded holes pre-drilled on the plate surface for locking with the beam plate. No special tooling is required for disassembly and assembly. The beam plate is a U-shaped integrated load-bearing platform with a diamond-shaped anti-slip pattern pressed on the surface to increase the friction between the bottom of the roller seat and the beam plate, preventing lateral sliding and offset of the roller seat during lifting. The rear side of the beam plate has an integrated guide slider with a copper-based self-lubricating wear-resistant bushing embedded inside. The bushing can be removed and replaced individually, significantly reducing the wear caused by the reciprocating sliding of the beam plate in the groove 9, extending the service life of the entire lifting structure, and reducing the frequency of daily parts replacement.

[0034] When the first cylinder 202 in the control structure 2 is energized, the output end of the first cylinder 202 moves the top plate 203 upward, and the moving top plate 203 moves the beam plate 204 upward. At this time, the beam plate 204 drags the top support roller seat to adjust its position, so that the bearing position of the support roller seat is aligned with the position of the groove plate 307, so that the hydraulic tooling of the support roller seat can match various support roller seats without constantly changing the hydraulic tooling of the support roller seat.

[0035] The inner wall of the vertical plate 5 is threaded with a second screw 6. The second screw 6 rotates left and right through the inner wall of the vertical plate 5 under force. The inner side of the outer wall of the second screw 6 is rotatably connected to a bent plate 7. The inner side of the outer wall of the second screw 6 rotates through the bearing in the circular opening of the outer wall of the bent plate 7 under force. At the same time, when the second screw 6 rotates left and right, it will move the bent plate 7 left and right. The outer end of the second screw 6 is fixed with a second handle 8. The second handle 8 can form a force point with the hand. By holding the second handle 8 and rotating it, the second screw 6 will be rotated. The bottom of the bent plate 7 is in contact with the top of the beam plate 204. The beam plate 204 restricts the bent plate 7, making the bent plate 7 move in a stable linear motion and preventing the bent plate 7 from changing angle.

[0036] Two sets of upright plates 5 are symmetrically welded and fixed to the upper surface of the beam plate. The interior of the upright plates is milled with M18 standard threads. The second screw 6 is made of 45# quenched and tempered alloy steel, and the entire surface is hot-dip galvanized for rust prevention. The inner end of the screw is equipped with a flat thrust needle roller bearing. When the screw is rotated, it will not drive the bending plate to rotate synchronously, preventing scratches on the precision-machined outer surface of the roller seat during the clamping process. A 5mm thick high-elasticity polyurethane buffer pad is pasted on the inner bending working surface of the bending plate 7. The pad can be removed and replaced by countersunk screws. A flexible buffer is formed between the metal and the roller seat, eliminating hard contact that could cause scratches or bumps on the roller seat surface.

[0037] The second handle 8 is a star-shaped anti-slip handwheel with an outer diameter of 100mm. The surface is provided with multiple anti-slip grooves, which can be easily rotated by the operator wearing protective gloves. The left and right sets of curved plates feed and clamp synchronously, which can ensure that the central axis is consistent after the roller seats of different widths are placed. This effectively reduces the coaxiality deviation during hydraulic jacking and reduces the probability of bearing disassembly and assembly jamming and seal scratch failure.

[0038] The hydraulic structure 3 includes a second cylinder 301 and a round rod 302. The bottom of the second cylinder 301 is fixedly connected to the top of the bracket 4. The output end of the second cylinder 301 is fixedly connected to the rear end face of the round rod 302. Rib plates 303 are fixedly connected to the upper and lower sides of the round rod 302 respectively. A first screw 304 is rotatably connected to the outer wall of the rib plate 303. A slide plate 305 is threadedly connected to the outer wall of the first screw 304. A first handle 306 is fixedly connected to the outer end of the first screw 304. A groove plate 307 is fixedly connected to the front of the round rod 302. The opening of the outer wall of the groove plate 307 is slidably connected to the outer wall of the slide plate 305. The slide plate 305 slides up and down through the opening of the outer wall of the groove plate 307 under force. At the same time, the groove plate 307 restricts the slide plate 305, making the slide plate 305 move in a stable linear motion. The rear end face of the rib plate 303 is fixedly connected to the output end of the second cylinder 301.

[0039] The second cylinder 301 is a high-thrust hydraulic jacking cylinder with a rated output thrust of 150 tons, fully meeting the load requirements for press-fitting and disassembling various oil film bearings. The bottom of the cylinder is secured to the top of the bracket with flange bolts, and the cylinder can be lifted out entirely for maintenance by loosening the flange bolts. The round rod 302 is machined from solid forged 40Cr steel, providing high overall rigidity and preventing bending deformation during jacking operations. The upper and lower sets of rib plates 303 are symmetrically and fully welded to the outer wall of the round rod. Miniature deep groove ball bearings are press-fitted into the rib plates to support the first screw 304, resulting in low rotational resistance and allowing a single person to adjust the height of the sliding plate by hand.

[0040] The first handle 306 is a small, round, non-slip handwheel. Rotating the screw drives the slide plate 305 to slide up and down along the groove plate 307. The groove plate and slide plate combination support surface can be adapted to the outer rings of all bearings in the range of inner diameter 300mm-650mm. One set of tooling can complete the disassembly and assembly of multiple bearing models without changing the push end accessories, which greatly reduces the types of spare parts and storage space on site.

[0041] How to use the hydraulic tooling for supporting roller seats: Using the hydraulic tooling for the support roller seat: Place the bottom of the support roller seat against the top of the beam plate 204, then hold the second handle 8 and rotate the second screw 6 inward through the vertical plate 5. The rotating second screw 6 moves the bent plate 7 inward against the beam plate 204, so that the inner side of the bent plate 7 is against the outer wall of the support roller seat. Then, make the front of the support roller seat fit against the inner bend of the bent plate 7. Continue to rotate the second screw 6 so that the bent plate 7 clamps the support roller seat.

[0042] Next, the first cylinder 202 is energized, and its output end moves the top plate 203 upwards. The moving top plate 203 then moves the beam plate 204 upwards. At this time, the beam plate 204, dragging the top support roller seat, adjusts its position so that the bearing position of the support roller seat aligns with the position of the groove plate 307. Before officially starting the roller seat disassembly and assembly operation, it is necessary to connect the tooling's hydraulic oil supply station in advance, check all hydraulic pipeline joints for leaks, and ensure the oil pressure gauge readings are within the equipment's standard range. Simultaneously, use a wire brush and compressed air to clean the surface of the beam plate of accumulated iron oxide scale, oil stains, and metal debris to prevent the bottom of the roller seat from tilting after placement. When using a workshop crane to lift the support roller seat, control the crane to lower it slowly, and prohibit heavy objects from directly impacting the beam plate to prevent deformation under load.

[0043] When operating the second handles on both sides, ensure that the number of rotations of the left and right screws is exactly the same, allowing the two sets of curved plates to feed inward synchronously to clamp the roller seat. This ensures that the center axis of the roller seat coincides with the center line of the hydraulic jacking structure, eliminating coaxiality errors caused by unilateral force. When adjusting the lifting height of the first cylinder, use inching control for slow lifting and repeated small adjustments to the beam plate height until the bearing end face inside the roller seat is completely parallel and aligned with the end face of the groove plate 307. This reduces the risk of scratches and jamming on the bearing sealing surface during subsequent jacking processes.

[0044] When the second cylinder 301 is energized, its output end moves the round rod 302 forward. The moving round rod 302 moves the grooved plate 307 forward, causing the front of the grooved plate 307 to fit against the bearing inside the support roller seat. Then, the extension of the output end of the second cylinder 301, in conjunction with the round rod 302 and the grooved plate 307, pushes the bearing out of the support roller seat. If the support range of the grooved plate 307 is smaller than the outer diameter of the bearing, the first handle 306 is gripped and the first screw 304 is rotated. The rotating first screw 304 moves the sliding plate 305 outward, expanding the combined support surface of the grooved plate 307 and the sliding plate 305, allowing the outer wall of the sliding plate 305 to fit completely against the outer ring of the bearing.

[0045] The bearing jacking and disassembly operation is carried out in stages with increased pressure. First, low-pressure oil supply is used to slowly push the groove plate to fit against the bearing end face. After confirming that the contact is uniform around the perimeter and there are no local gaps, the oil pressure is gradually increased to the rated working thrust. Throughout the operation, a dedicated person is assigned to observe the contact status between the roller seat and the beam plate. If the roller seat shifts or abnormal noise occurs, the pressure is immediately released and the jacking is stopped. The alignment problem is then investigated before continuing the operation. When dealing with large-diameter heavy bearings, the two sets of sliding plates 305 are adjusted synchronously to expand the overall support contact area, distribute the jacking pressure, and avoid local stress concentration in the groove plate, which could lead to cracking and deformation. After the bearing is completely removed from the inside of the roller seat, the second cylinder is controlled to slowly retract and reset. The bearing is supported by the tooling structure to prevent it from falling freely and damaging the precision mating working surfaces.

[0046] After the support roller seat is processed, the second handle 8, along with the second screw 6, rotates outward through the vertical plate 5. The rotating second screw 6 moves the bent plate 7 outward, causing the bent plate 7 to detach from the outer wall of the support roller seat. Then, the support roller seat is removed from the top of the beam plate 204. After a single roller seat assembly and disassembly is completed, the hydraulic structure is first fully retracted, and the first cylinder lowers the beam plate to its lowest limit. Then, the bent plates on both sides are released simultaneously to release the clamps. Finally, the roller seat is smoothly lifted away by the overhead crane.

[0047] After all maintenance work is completed each day, apply high-temperature and extreme-pressure grease to moving parts such as groove 9, screw threads, and sliding plate, and clean the bearing grease and metal debris adhering to the surface of the groove plate and sliding plate; regularly check the wear of cylinder seals and bearing bushings every week, and replace parts in time if problems such as hydraulic leakage, sliding jamming, or pad damage occur, to ensure that the tooling is stable and adaptable to the maintenance work of various specifications of support roller seats for a long time.

[0048] All components of the entire tooling set adopt a modular, separate assembly design. The lifting control structure, hydraulic jacking structure, and side clamping and positioning components can all be disassembled and replaced individually. On-site operators can complete the equipment assembly, debugging, and commissioning by following the structural dimensions, assembly steps, and adjustment procedures described in this document. The three functions of lifting height adjustment, roller seat width clamping, and jacking support surface self-adaptation are independent of each other, and the adjustment operations do not interfere with each other. It is suitable for continuous roller system maintenance between hot rolling and cold rolling mills. A single tooling set can replace multiple traditional dedicated roller seat tooling sets, saving workshop space and equipment procurement investment. The overall structure is simple to operate, and the daily maintenance process is convenient. It can stably meet the disassembly and assembly needs of multiple specifications of support roller seats for a long time.

Simultaneously, use a wire brush and compressed air to clean the surface of the beam plate of accumulated iron oxide scale, oil stains, and metal debris to prevent the bottom of the roller seat from tilting after placement. When using a workshop overhead crane to lift the support roller seat, control the crane to lower it slowly, and prevent heavy objects from directly impacting the beam plate to avoid deformation under load.
