Description

Technical Field

[0001] This utility model relates to the field of replacement devices, specifically a device for quickly replacing the AGC cylinder of a roughing mill. Background Technology

[0002] The roughing mill is a key piece of equipment in steel rolling production. It is mainly used for the preliminary rolling of steel billets. It can roll steel billets (such as slabs, square billets, etc.) at high temperature into intermediate rolled products with certain dimensions and shapes through the pressure of the rolls, providing qualified billets for the subsequent finishing rolling process.

[0003] The AGC cylinder in a roughing mill is a core actuator that enables automatic thickness control. It is a type of hydraulic cylinder that precisely controls the pressure between the rolls to adjust the thickness of the rolled material during the rolling process. This ensures that the thickness of the intermediate rolled material meets the process requirements and provides qualified billets for the subsequent finishing rolling process. During the operation of the roughing mill, the AGC cylinder plays a crucial control role, accurately controlling the pressure of the rolls and ensuring the dimensional accuracy of the rolled material.

[0004] When an AGC cylinder malfunctions and needs to be replaced, traditional replacement methods present numerous problems. Typically, replacing an AGC cylinder requires stopping the roughing mill, then manually lifting and removing the old cylinder using cranes or other lifting equipment, and finally transporting the new cylinder to the installation location. During this process, due to the large size and weight of the AGC cylinder, and the limited space at the installation location, not only are multiple workers required to work together, consuming a large amount of manpower, but the entire replacement process is also extremely time-consuming, often taking several hours or even longer. This severely impacts the normal production rhythm of the roughing mill and reduces production efficiency.

[0005] Therefore, we propose a device for quickly changing the AGC cylinder of a roughing mill. Utility Model Content

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.

[0033] Please see Figures 1-5 In this embodiment of the present invention, a device for quickly changing the AGC cylinder of a roughing mill includes a guide seat 1. A movable plate 5 is slidably mounted on the upper surface of the guide seat 1 in the horizontal direction. A first hydraulic cylinder 9 is mounted in the middle of the upper surface of the movable plate 5. The output rod of the first hydraulic cylinder 9 faces upward. A roughing mill AGC cylinder support plate 13 is fixedly mounted on the upper end of the output rod of the first hydraulic cylinder 9. Fixed plates 14 are fixed at both ends of the upper surface of the roughing mill AGC cylinder support plate 13. A second hydraulic cylinder is fixedly mounted in the middle of the surface of the fixed plate 14 on the side away from the fixed plate 14. The output rods of the first hydraulic cylinder 10 and the second hydraulic cylinder 10 both face the fixed plate 14 and pass through the two sides of the middle part of the fixed plate 14. The opposite ends of the output rods of the second hydraulic cylinder 10 are fixedly installed with clamping blocks 15. When in use, it is convenient and quick to replace the roughing mill AGC cylinder. When replacing the roughing mill AGC cylinder, it helps to save the manpower and material resources required, and saves the time required to replace the roughing mill AGC cylinder, so as to ensure the normal production rhythm of the roughing mill and help to ensure the production efficiency of the roughing mill.

[0034] The movable plate 5 is in a horizontal state, and limit cylinders 11 are fixed at the four corners of the upper surface of the movable plate 5. The limit cylinders 11 are all in a vertical state, and limit rods 12 are slidably installed in the vertical direction inside the limit cylinders 11. The limit cylinders 11 can limit the limit rods 12, which facilitates the stable movement of the limit rods 12. The limit rods 12 are all in a vertical state, and the upper ends of the limit rods 12 are fixedly connected to the corresponding positions on the lower surface of the roughing mill AGC cylinder support plate 13. The limit rods 12 can limit the roughing mill AGC cylinder support plate 13.

[0035] A drive slider 4 is installed in the middle of the lower surface of the movable plate 5. A retaining groove 2 is opened in the middle of the upper surface of the guide seat 1 corresponding to the drive slider 4. The retaining groove 2 passes through the two ends of the guide seat 1 at the corresponding position. The drive slider 4 helps to drive the movable plate 5 to move in the horizontal direction. A guide rail 3 matching the drive slider 4 is installed at the bottom of the retaining groove 2 on the guide seat 1. The guide rail 3 is in a horizontal state. The drive slider 4 and the guide rail 3 are slidably installed in the horizontal direction. The guide rail 3 can limit the drive slider 4, which is conducive to the movement of the drive slider 4.

[0036] Both ends of the movable plate 5 are fixed with connecting plates 6, which are vertical. The bottom of the opposite sides of the connecting plates 6 are fixed with locking blocks 7, which can limit the movement of the movable plate 5. Both sides of the guide seat 1 are provided with locking grooves 8 corresponding to the locking blocks 7. The locking grooves 8 are horizontal, which helps to assemble the various components in this replacement device. The locking grooves 8 penetrate both ends of the guide seat 1 at the corresponding positions. The locking blocks 7 are slidably connected to the corresponding locking grooves 8 on the guide seat 1 in the horizontal direction. The locking grooves 8 on the guide seat 1 help to limit the locking blocks 7.

[0037] The working principle of this utility model is as follows: During use, the guide seat 1 is installed at the location where it needs to be installed on the external roughing mill. When it is necessary to assemble the roughing mill AGC cylinder, the roughing mill AGC cylinder is placed between the clamping blocks 15 on the upper surface of the roughing mill AGC cylinder support plate 13. The second hydraulic cylinder 10 is then opened. When the second hydraulic cylinder 10 is open, the output rod of the second hydraulic cylinder 10 can drive the clamping blocks 15 to move toward the roughing mill AGC cylinder. The clamping blocks 15 can clamp and limit the roughing mill AGC cylinder, which facilitates the stable assembly and use of the roughing mill AGC cylinder.

[0038] When the installation position of the roughing mill AGC cylinder needs to be adjusted horizontally, the drive slider 4 is opened. When the drive slider 4 is open, it moves horizontally along the guide rail 3. When the drive slider 4 moves, it can drive the moving plate 5 to move horizontally. When the moving plate 5 moves, it can drive the locking block 7 to move along the slot 8 on the guide seat 1 through the connecting plate 6. The guide seat 1 can limit the moving plate 5 through the slot 8, the locking block 7 and the connecting plate 6, so as to facilitate the stable movement of the moving plate 5. When the moving plate 5 moves, it can drive the roughing mill AGC cylinder support plate 13 and the roughing mill AGC cylinder clamped and limited on the upper side of the roughing mill AGC cylinder support plate 13 to move horizontally through the first hydraulic cylinder 9, the limiting cylinder 11 and the limiting rod 12, so as to adjust the assembly position of the roughing mill AGC cylinder.

[0039] After moving the roughing mill AGC cylinder to the required assembly position, the first hydraulic cylinder 9 is opened. With the first hydraulic cylinder 9 open, the output rod of the first hydraulic cylinder 9 can drive the roughing mill AGC cylinder support plate 13 to move vertically upward. When the roughing mill AGC cylinder support plate 13 moves, it can drive the limiting rod 12 to move vertically along the inner side of the limiting cylinder 11. The limiting cylinder 11 can limit the roughing mill AGC cylinder support plate 13 through the limiting rod 12, which helps to move the roughing mill AGC cylinder support plate 13 stably. When the roughing mill AGC cylinder support plate 13 moves, it can drive the roughing mill AGC cylinder clamped and limited on the upper side to move vertically. After moving the roughing mill AGC cylinder upward to the corresponding position inside the roughing mill, the roughing mill AGC cylinder can be assembled.

[0040] By moving the roughing mill AGC cylinder vertically and horizontally, it is easy to assemble or disassemble the roughing mill AGC cylinder. During use, it is convenient and quick to replace the roughing mill AGC cylinder, which helps to save manpower and material resources and time when replacing the roughing mill AGC cylinder, so as to ensure the normal production rhythm of the roughing mill and help to ensure the production efficiency of the roughing mill.
