Description

Technical Field

[0001] This utility model relates to the field of oil replenishment technology for work rolls, and in particular to an oil replenishment device for finishing mill work rolls. Background Technology

[0002] In existing technology, the oil replenishment of finishing mill work rolls adopts a fixed cycle mode. As the rolling speed, temperature, and rolling force gradually increase from the front to the back of the mill stand during the finishing mill rolling process, the wear of the bearings will also gradually increase, and the amount of oil replenishment will also increase accordingly. Since the bearing disassembly and maintenance cycle is long, regularly replenishing the bearings in the bearing housing has become one of the daily maintenance tasks of bearings to ensure the bearing's service life in the machine.

[0003] The strategy has the following problems: the existing oil replenishment device replenishes more oil to the rear frame than to the front frame during oil replenishment. Therefore, it is necessary to extend the oil replenishment time of the rear frame to increase the amount of oil replenished to the rear frame. This method prolongs the oil replenishment time and reduces the utilization efficiency of the work roll. Utility Model Content

[0004] To address the technical problem that existing technologies require extending the oil replenishment time of the downstream stand to increase the amount of oil replenished, which in turn prolongs the oil replenishment time and reduces the efficiency of the work rolls, this invention provides an oil replenishment device for finishing mill work rolls.

[0005] The oil replenishment device for finishing mill work rolls provided by this utility model adopts the following technical solution:

[0006] A finishing mill work roll oil replenishment device includes an oil storage cylinder containing lubricating oil, an oil replenishment nozzle located at the bottom of the oil storage cylinder, and an oil quantity regulating component located above the oil replenishment nozzle to regulate the oil output of the oil replenishment nozzle. An internal regulating component is located inside the oil storage cylinder to adjust the oil output of the oil replenishment nozzle, and a torque steering component is connected between the internal regulating component and the oil quantity regulating component to redirect the torque of the oil quantity regulating component.

[0007] By adopting the above technical solution, the torque of the oil quantity adjustment component is redirected by the torque steering component. Rotating the oil quantity adjustment component can increase the oil output of the oil replenishment nozzle by multiple times, making it easier for operators to accurately determine the amount of oil replenishment, shortening the oil replenishment time, and improving the utilization efficiency of the work roll.

[0008] Furthermore, the oil storage tank has openings at both the top and bottom, a sealing cap is provided on the upper part of the oil storage tank, a filter cap is provided on the lower part of the oil storage tank, and the oil replenishment nozzle is located above the filter cap.

[0009] By adopting the above technical solution: when in use, lubricating oil is added through the top opening of the oil reservoir, and the top opening of the oil reservoir is sealed with a sealing cap. By setting a filter cap, impurities in the lubricating oil in the oil reservoir are deposited in the filter cap, preventing them from entering the gears.

[0010] Furthermore, a base plate is fixedly connected to the inner wall of the oil reservoir, and the internal adjustment assembly includes an adjustment block that is slidably disposed in the oil replenishment nozzle, the adjustment block having a conical structure.

[0011] By adopting the above technical solution, the volume of the oil outlet in the oil filler nozzle can be adjusted by moving the adjusting block, thereby adjusting the oil output of the oil filler nozzle.

[0012] Furthermore, a slide rail is welded to the upper part of the base plate, and the bottom of the adjusting block on the side away from the oil filler nozzle forms a sliding connection with the slide rail. A support plate is also provided on the upper part of the base plate, and a screw is rotatably connected to the upper part of the support plate. One end of the screw passes through the support plate and is fixedly connected to a gear, and the other end extends into the oil filler nozzle and forms a threaded connection with the adjusting block.

[0013] By adopting the above technical solution: rotating the gear causes the screw to rotate, and the screw drives the adjusting block to slide on the slide rail. When the adjusting block slides into the oil filler nozzle, the volume of the oil outlet of the oil filler nozzle decreases, and the oil output of the oil filler nozzle decreases. When the adjusting block slides outward from the oil filler nozzle, the volume of the oil outlet of the oil filler nozzle increases, and the oil output of the oil filler nozzle increases.

[0014] Furthermore, the torque steering assembly includes an eccentric disc fixedly connected to the oil quantity adjustment assembly and transverse teeth slidably disposed at the bottom of the eccentric disc.

[0015] By adopting the above technical solution, the horizontal teeth can be driven to move by rotating the eccentric disk.

[0016] Furthermore, an mounting plate extends upward from the upper part of the base plate, and the transverse tooth is slidably disposed on the side of the mounting plate and meshes with the gear. A spring is disposed between the bottom of the transverse tooth and the base plate, with one end of the spring fixedly connected to the bottom wall of the transverse tooth and the other end fixedly connected to the top wall of the base plate.

[0017] By adopting the above technical solution: In the first state, the volume of the oil outlet of the oil filler nozzle decreases. Specifically, rotating the oil volume adjustment component causes the eccentric disc to drive the horizontal teeth to move downwards, the horizontal teeth drive the gear to rotate in the forward direction, and the adjustment block moves into the oil filler nozzle, thus reducing the volume of the oil outlet of the oil filler nozzle. In the second state, the volume of the oil outlet of the oil filler nozzle increases. Specifically, continuing to rotate the oil volume adjustment component causes the outer wall of the eccentric disc to move away from the horizontal teeth. Under the elastic force of the spring, the horizontal teeth move upwards and abut against the outer wall of the eccentric disc. The horizontal teeth drive the gear to rotate in the reverse direction, causing the adjustment block to move outwards from the oil filler nozzle, thus increasing the volume of the oil outlet of the oil filler nozzle.

[0018] Furthermore, the oil quantity regulating component includes a limiting seat disposed on the outer wall of the oil reservoir, the limiting seat being located above the oil replenishing nozzle; and a rotating plate rotatably disposed outside the limiting seat.

[0019] By adopting the above technical solution, the rotating plate is mounted on the outer wall of the oil storage tank.

[0020] Furthermore, a connecting rod is provided on the side of the rotating plate. The connecting rod passes through the limiting seat and extends into the interior of the oil reservoir. The end of the connecting rod located away from the rotating plate is fixedly connected to the eccentric disk. A fixing hole is provided on the side of the rotating plate near the limiting seat. A first fixing pin and a second fixing pin are provided on the limiting seat at positions corresponding to the fixing hole.

[0021] By adopting the above technical solution: rotating the rotating plate can drive the eccentric disk to rotate, and by making the fixing hole cooperate with the first fixing pin or the second fixing pin, the rotation position of the rotating plate is fixed.

[0022] In summary, the beneficial effects of this utility model are as follows:

[0023] This utility model, by setting up an oil quantity adjustment component, a torque steering component, and an internal adjustment component, allows the oil replenishment device to replenish oil to the working rollers of the front frame. In the first state, the oil quantity adjustment component rotates, specifically by rotating the rotating plate in the oil quantity adjustment component, causing the eccentric disc to drive the horizontal teeth to move downwards, causing the adjustment block to move into the oil replenishment nozzle, reducing the volume of the oil outlet of the oil replenishment nozzle, and reducing the oil output of the oil outlet of the oil replenishment nozzle. At this time, the fixing hole in the rotating plate cooperates with the first fixing pin to fix the rotation position of the rotating plate, and then replenishes oil to the working rollers of the front frame for a rated time.

[0024] When replenishing oil to the work rolls of the rear frame, the oil quantity adjustment component is rotated to the second state. Specifically, the rotating plate in the oil quantity adjustment component is rotated further, causing the outer wall of the eccentric disk to move away from the horizontal teeth. Under the elastic force of the spring, the horizontal teeth move upward and abut against the outer wall of the eccentric disk, causing the adjustment block to move outward of the oil replenishment nozzle. The volume of the oil outlet of the oil replenishment nozzle increases. At this time, the fixing hole cooperates with the second fixing pin to fix the position of the rotating plate. Subsequently, the work rolls of the rear frame can be replenished with oil for the same amount of time. Since the oil output of the oil replenishment nozzle in the second state is twice that in the first state, the operator can accurately control the increase in oil replenishment for the work rolls of the rear frame. By using the oil replenishment device with this structure, the oil replenishment time of the work rolls can be effectively shortened, and the utilization efficiency of the work rolls can be improved.

[0031] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0032] Reference Figure 1 As shown, this utility model discloses a finishing mill work roll oil replenishment device, including an oil storage cylinder 1, which stores lubricating oil. The oil storage cylinder 1 has openings at both the top and bottom. A sealing cover 11 is provided on the upper part of the oil storage cylinder 1, and a filter cover 12 is provided on the lower part of the oil storage cylinder 1. When in use, lubricating oil is added through the opening at the top of the oil storage cylinder 1. By setting the filter cover 12, impurities in the lubricating oil in the oil storage cylinder 1 are allowed to settle inside the filter cover 12, preventing them from entering the gears. An oil replenishment nozzle 2 is set at the bottom of the oil storage cylinder 1. Specifically, the oil replenishment nozzle 2 is set above the filter cover 12. When adding lubricating oil, the oil replenishment nozzle 2 is connected to the work roll oil replenishment port for oil replenishment, allowing impurities in the lubricating oil to settle inside the filter cover 12. An oil volume adjustment component 3 is set on the upper part of the oil replenishment nozzle 2 to adjust the oil output of the oil replenishment nozzle 2. By rotating the oil volume adjustment component 3, the oil output of the oil replenishment nozzle 2 can be increased by multiples, making it easy for the operator to accurately determine the increase in oil replenishment.

[0033] Furthermore, refer to Figure 2 and Figure 3As shown, an internal adjustment component 5 for adjusting the oil output of the oil supply nozzle 2 is provided inside the oil reservoir 1. A torque steering component 4 is connected between the internal adjustment component 5 and the oil quantity adjustment component 3. The torque steering component 4 can steer the torque of the oil quantity adjustment component 3 so that the internal adjustment component 5 can be driven to adjust the oil output when the oil quantity adjustment component 3 is rotated.

[0034] Specifically, a base plate 14 is fixedly connected to the inner wall of the oil reservoir 1. The internal adjustment assembly 5 includes an adjustment block 53 slidably disposed inside the oil filler nozzle 2. The adjustment block 53 has a conical structure. By moving the adjustment block 53, the volume of the oil outlet in the oil filler nozzle 2 can be adjusted, thereby adjusting the oil output of the oil filler nozzle 2. Preferably, a slide rail 55 is welded to the upper part of the base plate 14. The bottom of the adjustment block 53 on the side away from the oil filler nozzle 2 is slidably connected to the slide rail 55. A support plate 54 is also provided on the upper part of the base plate 14. The upper part of the support plate 54 is rotatably connected to... There is a screw 52. One end of the screw 52 passes through the support plate 54 and is fixedly connected to the gear 51. The other end extends into the oil filler nozzle 2 and forms a threaded connection with the adjusting block 53. In use, the gear 51 is rotated, which drives the screw 52 to rotate. The screw 52 drives the adjusting block 53 to slide on the slide rail 55. When the adjusting block 53 slides into the oil filler nozzle 2, the volume of the oil outlet of the oil filler nozzle 2 decreases and the oil output of the oil filler nozzle 2 decreases. When the adjusting block 53 slides out of the oil filler nozzle 2, the volume of the oil outlet of the oil filler nozzle 2 increases and the oil output of the oil filler nozzle 2 increases.

[0035] Reference Figure 3As shown, the torque steering assembly 4 includes an eccentric disk 41 fixedly connected to the oil level regulating assembly 3 and a transverse tooth 42 slidably disposed at the bottom of the eccentric disk 41. Specifically, a mounting plate 43 extends upward from the upper part of the base plate 14, and the transverse tooth 42 is slidably disposed on the side of the mounting plate 43 and meshes with the gear 51. A spring 44 is disposed between the bottom of the transverse tooth 42 and the base plate 14. One end of the spring 44 is fixedly connected to the bottom wall of the transverse tooth 42, and the other end is fixedly connected to the top wall of the base plate 14. Under the elastic force of the spring 44, the top of the transverse tooth 42 is always in contact with the outer wall of the eccentric disk 41. In use, in the first state, the volume of the oil outlet of the oil filler nozzle 2 decreases. Specifically, rotating the oil volume adjustment component 3 causes the eccentric disk 41 to drive the horizontal gear 42 to move downwards, the horizontal gear 42 drives the gear 51 to rotate forwards, and the adjusting block 53 moves inwards towards the oil filler nozzle 2, thus reducing the volume of the oil outlet of the oil filler nozzle 2. In the second state, the volume of the oil outlet of the oil filler nozzle 2 increases. Specifically, continuing to rotate the oil volume adjustment component 3 causes the outer wall of the eccentric disk 41 to move away from the horizontal gear 42, under the elastic force of the spring 44... The lower horizontal tooth 42 moves upward and contacts the outer wall of the eccentric disk 41. The horizontal tooth 42 drives the gear 51 to rotate in the opposite direction, causing the adjusting block 53 to move outward of the oil replenishing nozzle 2. The volume of the oil outlet of the oil replenishing nozzle 2 increases, and the volume of the oil outlet of the lower oil replenishing nozzle 2 in the second state is twice that of the oil outlet of the oil replenishing nozzle 2 in the first state. As a result, the oil output of the lower oil replenishing nozzle 2 in the second state is twice that of the oil replenishing nozzle 2 in the first state. The operator can accurately grasp the increase in oil replenishment of the downstream frame work roller.

[0036] Reference Figure 4 and Figure 5 As shown, the oil quantity regulating component 3 includes a limiting seat 31 disposed on the outer wall of the oil reservoir 1. Specifically, the limiting seat 31 is located above the oil filler nozzle 2. A rotating plate 32 is rotatably disposed outside the limiting seat 31. A connecting rod 33 is disposed on the side of the rotating plate 32. The connecting rod 33 passes through the limiting seat 31 and extends into the interior of the oil reservoir 1. The end of the connecting rod 33 located away from the rotating plate 32 is fixedly connected to the eccentric disk 41. A fixing hole 321 is disposed on the side of the rotating plate 32 near the limiting seat 31. A first fixing pin 311 and a second fixing pin 312 are disposed on the limiting seat 31 at positions corresponding to the fixing hole 321. The rotational position of the rotating plate 32 is fixed by engaging the fixing hole 321 with the first fixing pin 311 or the second fixing pin 312.

[0037] When using this oil replenishing device to replenish oil to the working rollers of the front frame, the oil quantity adjustment component 3 is rotated in the first state. Specifically, the rotating plate 32 in the oil quantity adjustment component 3 is rotated, causing the eccentric disk 41 to drive the horizontal gear 42 to move downward. The horizontal gear 42 drives the gear 51 to rotate in the forward direction, and the adjusting block 53 moves into the oil replenishing nozzle 2. The volume of the oil outlet of the oil replenishing nozzle 2 decreases, and the oil output of the oil outlet of the oil replenishing nozzle 2 decreases. At this time, the fixing hole 321 in the rotating plate 32 cooperates with the first fixing pin 311 to fix the rotation position of the rotating plate 32. Then, the working rollers of the front frame are replenished with oil for the rated time.

[0038] When replenishing oil to the work rolls of the rear frame, the oil quantity adjustment component 3 is rotated to the second state. Specifically, the rotating plate 32 in the oil quantity adjustment component 3 is rotated further, causing the outer wall of the eccentric disk 41 to move away from the horizontal tooth 42. Under the elastic force of the spring 44, the horizontal tooth 42 moves upward and contacts the outer wall of the eccentric disk 41. The horizontal tooth 42 drives the gear 51 to rotate in the opposite direction, causing the adjustment block 53 to move outward of the oil replenishing nozzle 2. The volume of the oil outlet of the oil replenishing nozzle 2 increases. At this time, the fixing hole 321 cooperates with the second fixing pin 312 to fix the position of the rotating plate 32. Subsequently, the work rolls of the rear frame can be replenished with oil for the same amount of time. Since the oil output of the oil replenishing nozzle 2 in the second state is twice that in the first state, the operator can accurately grasp the increase in oil replenishment of the work rolls of the rear frame. By using the oil replenishing device with this structure, the oil replenishment time of the work rolls can be effectively shortened, and the utilization efficiency of the work rolls can be improved.
