Technical Field

[0001] The utility model relates to the technical field of rolling mill accessories, in particular to a load-bearing structure for a three-roll reducing and sizing precision rolling mill. Background Technique

[0002] When rolling materials such as steel by rolls, huge rolling forces will be generated. These forces are transmitted from the rolls to the bearing seats, and then from the bearing seats to load-bearing structures such as the frame. The load-bearing structure needs to evenly disperse and bear these forces to prevent structural damage caused by local overload. The existing assembly steps of the load-bearing bearings and the rolling mill are complicated, and it is not convenient to replace when the load-bearing bearings are damaged.

[0003] In the prior art, for example, a load-bearing bearing for a three-roll reducing and sizing precision rolling mill in Chinese Patent CN 215355342 U includes an outer ring and an inner ring. The inner ring is arranged inside the outer ring. A plurality of rollers are provided on the outer peripheral surface of the inner ring, and the inner ring and the outer ring are movably connected through a plurality of rollers. The plurality of rollers are symmetrically distributed about the inner ring. A support block is provided on the outer side of the outer ring, and both the outer ring and the inner ring are embedded in the support block. A fixing mechanism is provided on the inner side of the bottom of the support block. In the utility model, by rotating two limiting rings counterclockwise, the two limiting rings move towards the front ends of the first screw rod and the second screw rod respectively. After the outer ring is placed inside the sliding seat, the sliding seat is then pushed into the support block, and the two limiting rings move towards the rear ends of the first screw rod and the second screw rod respectively, fixing the sliding seat inside the support block, thus completing the assembly. The assembly steps of this load-bearing bearing and the rolling mill are simple. When the load-bearing bearing is damaged, it is convenient to disassemble and replace from the rolling mill. However, the patent still has the following problems.

[0004] In the above patent, although the patent is provided with the first screw rod and the second screw rod, and by rotating two limiting rings counterclockwise, the two limiting rings move towards the front ends of the first screw rod and the second screw rod respectively to fix the sliding seat, after long-term use, the threaded connection may be worn, and then it may cause the limiting ring to move after fixing, resulting in the fixing seat being fixed unstably. Summary of the Utility Model

Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1 - 5As shown in the figure, the utility model provides a load-bearing structure for a three-roll reducing and sizing precision rolling mill, which includes a fixed block 1. One end of the fixed block 1 is provided with a fixed groove 4. A fixed seat 5 is slidably installed inside the fixed groove 4. Two clamping grooves 10 are provided at the top of the fixed seat 5. Two limiting grooves 18 are provided on the inner wall of the fixed groove 4. Support plates 21 are fixedly installed on the inner walls of the two limiting grooves 18. Springs 22 are fixedly installed at the bottoms of the two support plates 21. A clamping block 23 is fixedly installed at the bottom of the spring 22. A connecting rod 24 is fixedly installed at the top of the clamping block 23. The top of the connecting rod 24 penetrates through the support plate 21. A connecting groove 19 is penetrated between the two limiting grooves 18. A moving plate 25 is fixedly installed at the tops of the two connecting rods 24. The moving plate 25 is slidably connected with the connecting groove 19. A through hole 13 is penetrated through the inner wall of the connecting groove 19. A pulling plate 14 is fixedly installed on the outer wall of the moving plate 25. The pulling plate 14 is slidably connected with the through hole 13. A first handle 6 is fixedly installed on the outer wall of the fixed seat 5.

[0025] The effect achieved by the entire embodiment 1 is that during fixation, the staff pulls the pulling plate 14. The pulling plate 14 drives the connecting rod 24 to rise through the moving plate 25, and then drives the clamping block 23 to rise. The clamping block 23 enters the limiting groove 18, and the spring 22 is compressed. Then the staff pushes the fixed seat 5 into the fixed groove 4 and releases the pulling plate 14. The elastic force of the spring 22 pushes the clamping block 23 into the clamping groove 10. At this time, the fixed seat 5 is fixed, and the unstable fixation of the fixed seat 5 can be prevented.

[0026] Embodiment 2, as Figures 1 - 5 shown, further, a connecting belt 15 is fixedly installed on the outer wall of the fixed block 1. A stop block 16 is fixedly installed at one end of the connecting belt 15. A second handle 17 is fixedly installed on the outer wall of the stop block 16. The outer wall of the stop block 16 is in fit with the inner wall of the through hole 13.

[0027] Further, a storage groove 20 is provided on the inner wall of the connecting groove 19. A magnet 26 is fixedly installed on the inner wall of the storage groove 20.

[0028] Further, an outer ring 7 is arranged inside the fixed seat 5. An inner ring 8 is arranged inside the outer ring 7. A plurality of rollers 9 are arranged between the outer ring 7 and the inner ring 8.

[0029] Further, sliding blocks 11 are fixedly installed on both sides of the outside of the fixed seat 5. Sliding grooves 12 are provided on both sides inside the fixed groove 4. The two sliding blocks 11 are respectively slidably connected with the two sliding grooves 12 to prevent the fixed seat 5 from completely disengaging from the fixed block 1.

[0030] Further, mounting plates 2 are fixedly installed on both sides of the outside of the fixed block 1. A plurality of uniformly distributed mounting holes 3 are penetrated through the tops of the mounting plates 2.

[0031] Further, the outer walls of the two clamping blocks 23 are respectively attached to the inner walls of the two clamping grooves 10, preventing the fixing seat 5 from shaking after the clamping blocks 23 enter the clamping grooves 10.

[0032] The effect achieved by the entire Embodiment 2 is that after fixation, the staff inserts the stopper 16 into the through hole 13 and continues to push the stopper 16. The stopper 16 enters the storage groove 20. The iron stopper 16 is attracted by the magnet 26 and adsorbed on the magnet 26. At this time, the stopper 16 can prevent dust from entering the through hole 13, reducing the cleaning burden on the staff.

[0033] Working principle: During fixation, the staff first passes a bolt through the mounting hole 3 to install the mounting plate 2 on the machine frame. Then, the staff pulls the pull plate 14. The pull plate 14 drives the connecting rod 24 to rise through the moving plate 25, and then drives the clamping block 23 to rise. The clamping block 23 enters the limiting groove 18, and the spring 22 is compressed. Then, the staff pushes the fixing seat 5 into the fixing groove 4 and releases the pull plate 14. The elastic force of the spring 22 pushes the clamping block 23 into the clamping groove 10. At this time, the fixing seat 5 is fixed, preventing the fixing seat 5 from being unstable. During disassembly, the staff pulls the pull plate 14, and the clamping block 23 leaves the clamping groove 10. The staff can then pull the first handle 6 to extract the fixing seat 5 and the outer ring 7, facilitating installation and disassembly. After fixation, the staff inserts the stopper 16 into the through hole 13 and continues to push the stopper 16. The stopper 16 enters the storage groove 20. The iron stopper 16 is attracted by the magnet 26 and adsorbed on the magnet 26. At this time, the stopper 16 can prevent dust from entering the through hole 13, reducing the cleaning burden on the staff. When using the pull plate 14, the staff pulls the second handle 17 to pull the stopper 16 away from the surface of the magnet 26, and finally extracts the stopper 16.

[0034] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
