Description

Technical Field

[0001] This utility model relates to the field of rolling mill guide plate technology, specifically to a precision rolling balance guide plate structure. Background Technology

[0002] In the hot continuous rolling process, the workpiece is first heated to a suitable rolling temperature in a furnace, and then conveyed to the roughing mill for preliminary rolling to give it the required shape and size. After roughing, the workpiece enters the finishing mill for more precise rolling to achieve the dimensional accuracy and surface quality requirements of the final product. At the entrance of the finishing mill, the guide plate plays a crucial role, guiding the workpiece accurately between the rolls to ensure the smooth progress of the rolling process.

[0003] However, during the operation of existing hot continuous rolling mills, the guide plates at the inlet are frequently subjected to hot and cold conditions and scraping from the tail of the rolled piece. As a result, the guide plates are prone to upward deformation and cannot be kept in the initial position, which leads to obstruction of the movement of the rolled piece and causes frequent steel pile-up accidents. Utility Model Content

[0004] The purpose of this invention is to provide a balanced guide plate structure for finishing mills to solve the problem that the guide plates at the entrance of existing hot continuous rolling mills are prone to upward deformation, which leads to obstruction of workpiece movement and frequent steel pile-up accidents.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a precision rolling balance guide plate structure, including a guide plate body and several counterweight bins. The bottom of the guide plate body is provided with a U-shaped crossbeam, and the bottom of the U-shaped crossbeam is provided with a through groove. Each counterweight bin is provided with a connecting rod, and each connecting rod is detachably connected to a limiting rod on both sides. Each limiting rod passes through the through groove from the outside to the inside and abuts against the U-shaped crossbeam.

[0006] The working principle of this utility model is as follows: a precision rolling balance guide plate structure, when it is necessary to install the counterweight bin, firstly move the limiting rod to the bottom of the through slot, adjust the position of the limiting rod left and right to make the limiting rod parallel to the through slot, then pass the limiting rod through the through slot at the bottom of the U-shaped crossbeam, and then place the limiting rod on the U-shaped crossbeam. After installation, the weight of the counterweight bin generates a downward pulling force on the guide plate body, balancing the upward deformation force of the guide plate, ensuring that the guide plate body remains in the initial position during the hot continuous rolling process, and guiding the rolled piece smoothly into the space between the rolls.

[0007] The beneficial effects of this utility model are as follows: by setting up a counterweight bin, connecting rod and limiting rod, the weight of the counterweight bin is used to balance the upward deformation force of the guide plate, effectively reducing the upward deformation of the guide plate, reducing the probability of the rolled piece being obstructed, reducing the occurrence of steel piling accidents, and ensuring the smooth progress of the hot continuous rolling production process.

[0008] Option 2, which is a preferred option of the basic option, has threads on both limiting rods and threaded holes on both sides of the connecting rod, and the two limiting rods are threadedly connected to the threaded holes; the threaded connection makes the installation and disassembly of the limiting rods more convenient.

[0009] Option 3, which is a preferred option of the basic option, has a door hinged to one side of the counterweight compartment, a counterweight block inside the counterweight compartment, and a limiting unit for limiting the door on one side of the counterweight compartment. By setting the door and the counterweight block, the weight inside the counterweight compartment can be flexibly adjusted according to actual needs, further improving the accuracy of the balance adjustment of the guide plate body.

[0010] Option 4, which is a preferred option of Option 3, includes an arc-shaped rod, one end of which is hinged to the door leaf. The counterweight chamber is provided with an arc-shaped sleeve for engaging the arc-shaped rod on the side near the door leaf. By limiting the door leaf with the arc-shaped rod and the arc-shaped sleeve, the door leaf can be prevented from opening accidentally during production, ensuring the stability of the counterweight block in the counterweight chamber. At the same time, the structure is simple and easy to operate.

[0011] Option 5, which is a preferred option of the basic option, has several limiting grooves at the bottom of the U-shaped crossbeam, which are located on both sides of the through groove. By setting the limiting grooves, the limiting rod can be further positioned and limited to prevent the limiting rod from moving laterally during operation.

[0012] Option 6, a preferred embodiment of Option 5, features an N-pole magnetic plate on each limiting rod and an S-pole magnetic plate in the limiting groove, with the limiting rod and groove magnetically connected. This magnetic connection not only enhances the stability of the connection between the limiting rod and the limiting groove but also further prevents the limiting rod from wobbling, ensuring that the counterweight chamber remains in a stable working state.

[0018] like Figures 1 to 3 The diagram shows a precision rolling balance guide plate structure, comprising a guide plate body 1 and several counterweight bins 2. A U-shaped crossbeam 3 is fixedly connected to the bottom of the guide plate body 1. A through groove 4 is opened at the bottom of the U-shaped crossbeam 3, and several limiting grooves 11 are opened at the bottom of the U-shaped crossbeam 3. The limiting grooves 11 are located on both sides of the through groove 4. A connecting rod 5 is welded to each counterweight bin 2. Limiting rods 6 are detachably connected to both sides of each connecting rod 5. Both limiting rods 6 are threaded, and threaded holes are provided on both sides of the connecting rod 5. The two limiting rods 6 are threadedly connected to the threaded holes. Each limiting rod 6 passes through the through groove 4 from the outside to the inside and abuts against the bottom of the limiting groove 11. A door leaf 7 is hinged to one side of the counterweight chamber 2. A counterweight block 8 is placed inside the counterweight chamber 2. A limiting unit for limiting the door leaf 7 is provided on one side of the counterweight chamber 2. The limiting unit includes an arc-shaped rod 9. One end of the arc-shaped rod 9 is hinged to the door leaf 7. An arc-shaped sleeve 10 for locking the arc-shaped rod 9 is provided on the side of the counterweight chamber 2 near the door leaf 7. An N-pole magnetic sheet is provided on each limiting rod 6. An S-pole magnetic sheet is provided inside the limiting groove 11. The limiting rod 6 and the limiting groove 11 are magnetically connected.

[0019] The implementation method of this embodiment is as follows: When it is necessary to install the counterweight bin 2, firstly, move the limiting rod 6 below the through groove 4, adjust the direction of the limiting rod 6 left and right so that the limiting rod 6 is parallel to the through groove 4, then pass the limiting rod 6 through the through groove 4 at the bottom of the U-shaped crossbeam 3, and then place the limiting rod 6 in the limiting groove 11. Next, rotate the arc rod 9 counterclockwise around the hinge point so that the arc rod 9 is taken out from the arc sleeve 10. Then, open the door 7 on one side of the counterweight bin 2, add or remove the counterweight block 8 into the counterweight bin 2 as needed, adjust the weight, rotate the arc rod 9 clockwise, and insert the arc rod 9 into the arc sleeve 10 to fix the door 7. After installation, the weight of the counterweight bin 2 generates a downward pulling force on the guide plate body 1, balancing the upward deformation force of the guide plate body 1, ensuring that the guide plate body 1 remains in the initial position during the hot continuous rolling process, and guiding the rolled piece smoothly into the space between the rolls.
