Description

Technical Field

[0001] This utility model relates to the field of rolling mill equipment, and in particular to a rolling mill balancing device with built-in multi-set spring balancing. Background Technology

[0002] The pressure processing process that changes the shape of steel ingots and billets between rotating rolls is called steel rolling. However, the term "rolling mill" usually refers only to the main equipment. Currently, as an important piece of equipment in metal processing, the rolling mill needs to maintain the balance between the upper and lower rolls during the rolling process to ensure rolling quality and equipment stability.

[0003] In existing rolling mills, the roll gap adjustment is mostly achieved using hydraulic cylinders (balancing cylinders). After the rolls are installed, a suitable roll gap is left according to process requirements. Then, the valve of the balancing cylinder is opened, and the rolls are supported by the piston rod. The valve of the balancing cylinder is then closed to maintain a constant pressure in the cylinder, thereby ensuring that the roll gap remains constant and reducing the impact force of the rolled steel on the rolls during steel passage. However, the existing technology still has some shortcomings. Achieving mill balance by adjusting the pressure of liquid or gas requires the installation of corresponding pump stations, valves, pipelines, and other auxiliary equipment. This results in a large footprint for the balancing device, is not conducive to energy conservation and environmental protection, and has a slow response speed, failing to meet the needs of high-speed rolling. Therefore, a mill balancing device with built-in multi-set spring balancing is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mill balancing device with built-in multi-set spring balancing, which aims to improve the existing technology of achieving mill balancing by adjusting the pressure of liquid or gas. This requires the installation of corresponding pump stations, valves, pipelines and other auxiliary equipment, which leads to a large footprint of the balancing device, is not conducive to energy conservation and environmental protection, and has a slow response speed, thus failing to meet the needs of high-speed rolling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mill balancing device with built-in multi-set spring balancing, comprising a fixed base, two fixed plates fixedly connected inside the fixed base, a connecting rod fixedly connected between the two fixed plates, a movable base slidably connected to the outer periphery of the connecting rod, a compression spring fixedly connected to one side of each of the two movable bases, the other ends of the two compression springs fixedly connected to the adjacent sides of the two fixed plates respectively, a connecting plate rotatably connected to the top of the movable base, a T-shaped block fixedly rotatably connected to the top of the connecting plate, the T-shaped block slidably connected to the middle of the fixed base, a top plate fixedly connected to the top of the T-shaped block, a damping rod fixedly connected between the fixed base and the T-shaped block, and a limit assembly fixedly connected to the bottom of the top plate;

[0006] With the above technical solution, when the top plate is squeezed, it will drive the T-block to move downward. When the T-block moves, the connecting plate can compress the compression spring. When the pressure on the top plate decreases, the compression spring can make the T-block and the top plate move upward. At the same time, the damping rod can make the T-block and the top plate move slowly.

[0007] Furthermore, the limiting component includes a limiting rod, which is fixedly connected to the bottom of the top plate, and a limiting groove is formed in the middle of the fixing seat, with the limiting rod slidably connected to the middle of the limiting groove;

[0008] The above technical solution can prevent the top plate from tilting during movement by using the limiting rod and limiting groove, thereby improving the processing effect of steel rolling.

[0009] Furthermore, a positioning block is fixedly connected to the bottom of the fixed base, and an installation plate is provided at the bottom of the fixed base. A second compression spring is fixedly connected inside the installation plate, and a locking block is fixedly connected to the other end of the second compression spring. The locking block and the positioning block are in contact. A slot is provided in the middle of the positioning block, and the locking block and the slot are inserted into each other. A disassembly component is slidably connected to the middle of the installation plate.

[0010] With the above technical solution, by inserting the positioning block into the mounting plate, the positioning block will squeeze the card block when it enters and compress the pressure spring two. When the card slot moves to the original position of the card block, the card block can be popped into the card slot under the action of the pressure spring two, so that the fixed seat can be installed quickly.

[0011] Furthermore, the disassembly assembly includes a pressure rod, a movable plate is fixedly connected to the outer periphery of the pressure rod, a connecting plate two is rotatably connected to the outer side of the movable plate, a pull plate is rotatably connected to the other side of the connecting plate two, and the other side of the pull plate is fixedly connected to the side of the locking block near the compression spring two;

[0012] Through the above technical solution, pressing the pressure rod can cause the movable plate to move. At this time, under the action of the second connecting plate, the pull plate can be moved, thereby separating the card block and the card slot, which facilitates the maintenance of the fixed seat and allows for quick replacement of the fixed seat.

[0013] Furthermore, a movable groove is provided in the middle of the fixed base, and the T-shaped block is slidably connected to the middle of the movable groove;

[0014] The above technical solution prevents the T-block from derailing during movement, thus preventing the T-block from failing to reset.

[0015] Furthermore, a positioning groove is provided on the top of the mounting plate, and the positioning block and the positioning groove are inserted into each other.

[0016] The above technical solution allows for quick alignment of the mounting base and the mounting plate via the positioning groove, thereby improving the installation speed of the mounting base.

[0017] Furthermore, a partition is slidably connected inside the mounting plate, and the partition is fixedly connected between the compression spring and the locking block;

[0018] The above technical solution can prevent the compression spring from being deformed and damaged due to the tilting and squeezing of the locking block.

[0019] Furthermore, a handle is fixedly connected to the end of the pressure rod away from the mounting plate;

[0020] The above technical solution allows users to press the lever more conveniently via the grip.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when the top plate is squeezed, it will drive the T-block to move downward. The T-block will compress the damping rod, and at the same time, it will drive the connecting plate to compress the compression spring. When the pressure on the top plate is removed, the top plate can be lifted upward under the action of the compression spring and the damping rod, so that the top plate can be slowly reset. This can reduce the floor space of the balancing device, thereby reducing the energy consumption required by the balancing device, and improving the response speed of the balancing device.

[0023] 2. In this utility model, by inserting the positioning block into the mounting plate, the locking block will compress the second spring as the positioning block enters. When the positioning block is fully inserted, the second spring can spring the locking block into the slot, thereby quickly installing the fixed seat. By pressing the pressure rod, the movable plate can drive the second connecting plate to move. As the second connecting plate moves, the pull plate can separate the locking block and the slot, thereby quickly removing the fixed seat. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a rolling mill balancing device with built-in multi-set spring balancing, including a fixed base 1. Two fixed plates 2 are fixedly connected inside the fixed base 1. A connecting rod 3 is fixedly connected between the two fixed plates 2. A movable base 4 is slidably connected to the outer periphery of the connecting rod 3. A compression spring 5 is fixedly connected to one opposite side of each of the two movable bases 4. The other ends of the two compression springs 5 ​​are respectively fixedly connected to the adjacent sides of the two fixed plates 2. A connecting plate 6 is rotatably connected to the top of the movable base 4. A T-block 7 is fixedly and rotatably connected. The T-block 7 is slidably connected to the middle of the fixed seat 1. A top plate 8 is fixedly connected to the top of the T-block 7. When the top plate 8 is pressed, it will drive the T-block 7 to move downward. When the T-block 7 moves, it can press the movable seat 4 through the connecting plate 6 and make the movable seat 4 move. When the movable seat 4 moves, it will compress the compression spring 5. When the pressure on the top plate 8 decreases, the movable seat 4 can be reset under the action of the compression spring 5. At the same time, the T-block 7 and the top plate 8 can be moved upward through the connecting plate 6.

[0033] Reference Figures 1-3A damping rod 9 is fixedly connected between the fixed base 1 and the T-block 7. The damping rod 9 makes the movement of the T-block 7 and the top plate 8 smooth, thereby avoiding the impact on the steel rolling process, reducing the footprint of the balancing device, reducing the energy consumption required by the balancing device, and improving the response speed of the balancing device. A movable groove 21 is provided in the middle of the fixed base 1. The T-block 7 is slidably connected in the middle of the movable groove 21. The movable groove 21 can limit the T-block 7, thereby preventing the T-block 7 from separating from the fixed base 1 during movement and causing the T-block 7 to be unable to reset. A limit component is fixedly connected to the bottom of the top plate 8.

[0034] Reference Figures 1-3 The limiting component includes a limiting rod 10, which is fixedly connected to the bottom of the top plate 8. A limiting groove 11 is opened in the middle of the fixed seat 1. The limiting rod 10 is slidably connected to the middle of the limiting groove 11. The limiting rod 10 and the limiting groove 11 can limit the top plate 8, thereby preventing the top plate 8 from tilting when moving, and improving the processing effect of steel rolling.

[0035] Reference Figure 4 and Figure 5 A positioning block 12 is fixedly connected to the bottom of the fixing base 1. A mounting plate 13 is provided at the bottom of the fixing base 1. A positioning groove 22 is provided on the top of the mounting plate 13. The positioning block 12 and the positioning groove 22 are inserted and matched. The positioning groove 22 can limit the positioning block 12, which can quickly align the fixing base 1 and the mounting plate 13, thereby improving the installation speed of the fixing base 1. A compression spring 14 is fixedly connected inside the mounting plate 13. A locking block 15 is fixedly connected to the other end of the compression spring 14. The locking block 15 is in contact with the positioning block 12. A locking groove 16 is provided in the middle of the positioning block 12. The locking block 15 and the positioning block 12 are in contact. The slot 16 is inserted and engaged. When the positioning block 12 enters the positioning groove 22, the positioning block 12 will contact the locking block 15. When the positioning block 12 and the locking block 15 are in contact, the locking block 15 will be squeezed and moved. When the locking block 15 moves, the compression spring 14 can be compressed, and the positioning block 12 can be inserted into the positioning groove 22. When the positioning block 12 is fully inserted, the slot 16 will move to the original position of the locking block 15, and the locking block 15 will not be squeezed by external force. Under the action of the compression spring 14, the locking block 15 can be popped into the slot 16, so that the fixing seat 1 can be installed conveniently.

[0036] Reference Figure 4 and Figure 5 The mounting plate 13 has a partition plate that is slidably connected inside. The partition plate is fixedly connected between the compression spring 14 and the locking block 15. The partition plate can prevent the locking block 15 from tilting when moving, thereby avoiding the compression spring 14 from being squeezed and deformed or damaged, and improving the service life of the compression spring 14. The mounting plate 13 has a disassembly assembly that is slidably connected in the middle.

[0037] Reference Figure 5 The disassembly assembly includes a pressure rod 17, a movable plate 18 fixedly connected to the outer periphery of the pressure rod 17, a connecting plate 19 rotatably connected to the outer side of the movable plate 18, and a pull plate 20 rotatably connected to the other side of the connecting plate 19. The other side of the pull plate 20 is fixedly connected to the side of the locking block 15 near the compression spring 14. By pressing the pressure rod 17, the pressure rod 17 can drive the movable plate 18 to move. When the movable plate 18 moves, it will cause the connecting plate 19 to tilt, and at the same time as the connecting plate 19 tilts, it will pull the pull plate 20, causing the pull plate 20 to move. At the same time as the pull plate 20 moves, the locking block 15 can be pulled out from the middle of the slot 16, thereby removing the fixing seat 1. This facilitates the maintenance of the fixing seat 1 and allows for quick replacement of the fixing seat 1. A handle is fixedly connected to the end of the pressure rod 17 away from the mounting plate 13, allowing the user to press the pressure rod 17 more conveniently.

[0038] Working principle: When the top plate 8 is compressed, it will drive the T-block 7 to move downward, and at the same time, it will compress the damping rod 9. When the T-block 7 moves, it will cause one side of the connecting plate 6 to flip. At the same time, when the connecting plate 6 flips, the other side of the connecting plate 6 will press against the movable seat 4 and cause the movable seat 4 to move. When the movable seat 4 moves, it will compress the compression spring 5. When the pressure on the top plate 8 is removed, the top plate 8 can be lifted upward under the action of the compression spring 5 and the damping rod 9, so that the top plate 8 can be slowly reset.

[0039] Specifically, by inserting the positioning block 12 into the mounting plate 13, the positioning block 12 will press the locking block 15 as it enters, and the locking block 15 will compress the second compression spring 14. When the slot 16 moves to the original position of the locking block 15, the locking block 15 can be popped into the slot 16 under the action of the second compression spring 14, thereby quickly installing the fixing seat 1. By pressing the pressure rod 17, the movable plate 18 can drive the second connecting plate 19 to move. When the second connecting plate 19 moves, it will flip over. At the same time as it flips over, the pull plate 20 can move, thereby separating the locking block 15 and the slot 16, thereby quickly removing the fixing seat 1.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
