Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, and in particular to a guide groove device for inter-mill transition. Background Technology

[0002] A conventional rolling mill mainly consists of rolls, stands, roll gap adjustment devices, roll temperature adjustment devices, transmission devices, lubrication systems, control systems, and roll removal devices. A precision rolling mill, in addition to the main components and devices of a conventional rolling mill, adds devices to ensure rolling precision. Due to their special cross-sectional dimensions, hot-rolled steel sheet piles contain significant internal stress in the base plate, sheet plate, and lugs during the rolling process. During production, the rolled piece may experience slight lateral bending and torsion during the finishing mill rolling process, affecting the rolled size and subsequent shaping of the piece. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned problems and deficiencies by proposing a guide groove device for transition between rolling mills: through this device, the rolled workpiece can be corrected between each universal rolling mill stand to prevent torsion and ensure that the rolled workpiece can smoothly enter the rolling mill.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A guide chute device for inter-mill transition includes a support frame. A support plate is installed on the top outer wall of the support frame, and a drive port is opened at the top center of the support plate. Bearing seats are installed at equal intervals at both ends of the drive port on the bottom outer wall of the support plate, and a drive roller is installed between the bearing seats. Limiting components one are provided at both ends of the two outer walls of the support frame, and limiting components two are installed at the center of both ends of the support frame. Limiting component one includes a stabilizing frame installed on the outer wall of the support frame and a hydraulic cylinder one installed at both ends of the top of the stabilizing frame. Limiting component two includes an extension frame installed at the center of both ends of the support frame, an adjustment port opened at the center of the top of the extension frame, and a sliding block slidably connected to the inner wall of the adjustment port.

[0005] Furthermore, a drive motor is installed on one side of the outer wall of the support plate at one end of the drive roller, and the output shaft of the drive motor is connected to one end of the drive roller.

[0006] Furthermore, a limiting side plate is installed on the outer wall of one end of the hydraulic cylinder, and the bottom outer wall of the limiting side plate is displaced on the top outer wall of the support plate.

[0007] Furthermore, a mounting base is installed at the center of the top of the extension frame, and a second hydraulic cylinder is installed in the mounting base, with the bottom end of the second hydraulic cylinder connected to the top of the sliding block.

[0008] Furthermore, the sliding blocks are mounted with rotating rods on the outer walls of their respective sides, and the rotating rods are rotatably connected to equally spaced limiting rollers on the outer walls of their respective sides.

[0009] Furthermore, there is a gap between the bottom of the limiting side plate and the top of the support plate.

[0010] Furthermore, the second hydraulic cylinder, the first hydraulic cylinder, and the drive motor are connected to the controller via wires, and the controller is connected to the power supply via wires.

[0011] The beneficial effects of this utility model are as follows: After the drive motor on one side of the support plate on the support frame starts, it drives the drive roller on the bearing seat to rotate. After the drive roller rotates, the steel plate is carried and moved by the drive roller under the limiting pressure of the limiting roller, which facilitates the conveying of the steel plate and makes it easy to use. The hydraulic cylinder moves the limiting side plate close to the steel plate, pushes the steel plate to the center of the support plate, and limits both sides of the steel plate, so as to limit the two ends of the steel plate and prevent it from deforming.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1:

[0016] Reference Figure 1-4As shown, a guide chute device for inter-mill transition includes a support frame 1. A support plate 2 is installed on the top outer wall of the support frame 1, and a drive port 3 is opened at the top center of the support plate 2. Bearing seats 4 are evenly distributed at both ends of the bottom outer wall of the support plate 2 at the drive port 3, and a drive roller 5 is installed between the bearing seats 4. Limiting components 1 7 are provided at both ends of the outer walls on both sides of the support frame 1, and limiting components 2 18 are installed at the center of both ends of the support frame 1. The limiting component 7 includes a stabilizing frame 8 installed on the outer wall of the support frame 1 and hydraulic cylinders 9 installed at both ends of the top of the stabilizing frame 8; A drive motor 6 is installed on one side of the outer wall of the support plate 2 at one end of the drive roller 5, and the output shaft of the drive motor 6 is connected to one end of the drive roller 5. A limiting side plate 10 is installed on the outer wall of one end of the hydraulic cylinder 9, and the bottom outer wall of the limiting side plate 10 is displaced on the top outer wall of the support plate 2. There is a gap between the bottom of the limiting side plate 10 and the top of the support plate 2; the hydraulic cylinder 9 drives the limiting side plate 10 to approach the steel plate, pushes the steel plate to the center of the support plate 2 and limits the two sides of the steel plate, so as to limit the two ends of the steel plate and prevent it from deforming.

[0017] Example 2:

[0018] Reference Figure 1-4 As shown, the limiting component 2 18 includes an extension frame 11 installed at the center of both ends of the support frame 1, an adjustment port 12 opened at the center of the top of the extension frame 11, and a sliding block 13 slidably connected to the inner wall of the adjustment port 12. A mounting base 16 is installed at the center of the top of the extension frame 11, and a hydraulic cylinder 17 is installed in the mounting base 16. The bottom end of the hydraulic cylinder 17 is connected to the top of the sliding block 13. The sliding blocks 13 are mounted on the outer wall of one side close to each other, and the rotating rods 14 are rotatably connected to the outer wall of one side close to each other, and the limiting rollers 15 are distributed at equal distances. The hydraulic cylinder 17, hydraulic cylinder 9, and drive motor 6 are connected to the controller via wires, and the controller is connected to the power supply via wires. After the drive motor 6 on the support plate 2 side of the support frame 1 starts, it drives the drive roller 5 on the bearing seat 4 to rotate. After the drive roller 5 rotates, the steel plate is carried and moved by the drive roller 15 under the limiting pressure of the limiting roller 15, which facilitates the conveying of the steel plate and makes it easy to use.

[0019] Working principle: During operation, the support plate 2 on the support frame 1 is used for hot rolling. The steel plate moves on the support plate 2 under the conveying of the rolling mill. At this time, the hydraulic cylinder 17 is activated and pushes the sliding block 13 to move the adjustment port 12 on the extension frame 11. The rotating rod 14 on the sliding block 13 and the limiting roller 15 descend to the top of the steel plate, limiting the steel plate and preventing the steel from deforming due to stress. The hydraulic cylinder 9 on the stabilizing frame 8 is activated. The hydraulic cylinder 9 drives the limiting side plate 10 to approach the steel plate, pushing the steel plate to the center of the support plate 2 and limiting both sides of the steel plate. When the hydraulic cylinder 9 drives the limiting side plate 10 to its maximum value, it is located at both ends of the limiting roller 15. Through this device, the rolled piece can be corrected between each universal rolling mill stand to prevent torsion and ensure that the rolled piece can smoothly enter the rolling mill. The controller model is Delta RMC150.
