Eight-roller coordinated steel strip oxide layer combined stripping press roll device

Abstract

This utility model discloses an eight-roller synergistic steel strip oxide layer stripping pressure roller device, including a base, symmetrical side seats installed on both sides of the top of the base, and eight straightening rollers installed between the two sets of side seats. By installing eight straightening rollers on the base, a drive motor synchronously drives the eight straightening rollers to rotate through a linkage gear. The upper four and lower four roller sets apply alternating bending stress to the steel strip, causing the oxide layer on the surface of the steel strip to peel off due to brittle fracture. Compared with the traditional five-roller method, this increases the stress application points, thereby effectively dispersing the load and avoiding stress concentration. Furthermore, through two sets of movable side rotating seats at the front end of the base, a servo motor drives a bidirectional lead screw to rotate, which in turn drives two sets of threaded sleeves to slide guide sliders along guide grooves. The guide sleeve and guide plate drive the two sets of side rotating seats to move in opposite directions, allowing the guide rollers on the two sets of side rotating seats to move laterally to match the width of the steel strip, thus enabling the device to adapt to steel strips of different widths.

Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to an eight-roller synergistic steel strip oxide layer stripping pressure roller device. Background Technology

[0002] In the steel manufacturing and deep processing sector, the treatment of the oxide layer on the surface of steel strips directly affects product quality and suitability for subsequent applications, and its importance is becoming increasingly prominent in downstream industries such as automobile manufacturing, home appliance production, and building decoration. The presence of the oxide layer not only affects the surface finish and coating adhesion of the steel strip, but may also cause problems such as cracking and delamination during subsequent processing such as stamping and welding.

[0003] While traditional five-roll straightening devices can achieve basic straightening functions, they suffer from uneven stress distribution and damage to the steel strip surface when dealing with oxide layer peeling. This is especially true when processing high-strength alloy steel and ultra-thin steel strips, where a single straightening process cannot simultaneously address oxide layer peeling and material integrity. To solve these problems, we propose an eight-roll synergistic steel strip oxide layer joint peeling pressure roller device. Summary of the Invention

[0004] The purpose of this invention is to provide an eight-roller coordinated steel strip oxide layer stripping pressure roller device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an eight-roller coordinated steel strip oxide layer stripping pressure roller device, comprising a base, symmetrical side seats installed on both sides of the top of the base, eight straightening rollers installed between the two sets of side seats in a staggered arrangement of four on top and four on the bottom, a drive motor installed outside the right side seat, the right ends of the straightening rollers meshing with each other through linkage gears, a sleeve installed at the front end of the base, a servo motor installed at the right end of the sleeve, a bidirectional lead screw rotatably connected inside the sleeve, the ends of the bidirectional lead screws being connected to the output ends of the servo motors, threaded sleeves threadedly connected to both sides of the bidirectional lead screws, a guide groove opened at the bottom end of the sleeve, the bottom ends of the threaded sleeves being slidably connected to the guide groove through guide sliders, a guide plate installed at the top of the left threaded sleeve, a guide plate installed at the top of the right threaded sleeve, the end of the guide plate being located inside the guide sleeve, a side rotating seat installed at the opposite end of the guide sleeve and the guide plate, and guide rollers rotatably connected inside both sets of side rotating seats.

[0006] As a further preferred embodiment of this technical solution, a control box is installed on the outer wall of the equipment base, a display panel is installed on the control box, and control buttons are provided at the lower end of the display panel. The input terminals of the drive motor and the servo motor are both electrically connected to the control box through wires.

[0007] As a further preferred embodiment of this technical solution, the thread directions on both sides of the bidirectional lead screw are opposite.

[0008] As a further preferred embodiment of this technical solution, the surface of the guide roller is coated with a polyurethane elastic layer.

[0009] As a further preferred embodiment of this technical solution, both the guide sleeve and the outer wall of the top of the guide plate are polished, and the edges of both the guide sleeve and the guide plate are rounded.

[0010] As a further preferred embodiment of this technical solution, the outer wall of the guide plate is fully fitted with the inner wall of the guide sleeve, and the guide plate and the guide sleeve are slidably connected.

[0011] This utility model provides an eight-roller coordinated steel strip oxide layer stripping pressure roller device, which has the following beneficial effects:

[0012] This invention features eight sets of straightening rollers mounted on a base. A drive motor synchronously rotates these rollers via a linkage gear. The upper four and lower four roller sets apply alternating bending stress to the steel strip, causing the oxide layer on the strip surface to peel off due to brittle fracture. Compared to the traditional five-roller system, this increases the stress application points, effectively dispersing the load and preventing stress concentration. Furthermore, two movable side rotating seats at the front of the base allow a servo motor to drive a bidirectional lead screw to rotate. This, in turn, causes two sets of threaded sleeves to slide along guide grooves, leading to guide plates and guide sleeves that move the two sets of side rotating seats in opposite directions. This allows the guide rollers on the two sets of side rotating seats to move laterally to match the width of the steel strip, enabling the device to adapt to steel strips of different widths.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0021] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0022] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, an eight-roller coordinated steel strip oxide layer stripping pressure roller device includes a base 1. Symmetrical side seats 2 are installed on both sides of the top of the base 1. Eight straightening rollers 3 are installed between the two sets of side seats 2, arranged in a staggered pattern of four on top and four on the bottom. A drive motor 4 is installed on the outside of the right side seat 2. The right ends of the straightening rollers 3 are meshed with each other through linkage gears 5. A sleeve 9 is installed at the front end of the base 1. A servo motor 10 is installed on the right end of the sleeve 9. A bidirectional lead screw 11 is rotatably connected inside the sleeve 9. The ends of the bidirectional lead screw 11 are all connected to the servo motor. The output end of 10 is connected, and threaded sleeves 12 are threadedly connected to both sides of the bidirectional lead screw 11. The bottom end of the sleeve 9 is provided with a guide groove 13. The bottom end of the threaded sleeve 12 is slidably connected to the guide groove 13 through the guide slider 14. A guide plate 15 is installed at the top of the left threaded sleeve 12, and a guide plate 16 is installed at the top of the right threaded sleeve 12. The end of the guide plate 16 is located inside the guide plate 15. A side rotating seat 17 is installed at one end opposite to the guide plate 15 and the guide plate 16. Guide rollers 18 are rotatably connected in both sets of side rotating seats 17.

[0023] By installing eight sets of straightening rollers 3 on the equipment base 1, the drive motor 4 synchronously drives the eight sets of straightening rollers 3 to rotate through the linkage gear 5. The upper four and lower four roller sets apply alternating bending stress to the steel strip, causing the oxide layer on the surface of the steel strip to peel off due to brittle fracture. Compared with the traditional five rollers, this increases the stress application points, thereby effectively dispersing the load and avoiding stress concentration. Then, through the two sets of movable side rotating seats 17 at the front end of the equipment base 1, when the steel strip moves to the front end of the equipment base 1, the servo motor 10 drives the bidirectional lead screw 11 to rotate, which drives the two sets of threaded sleeves 12 to drive the guide slider 14 to slide along the guide groove 13. The guide sleeve 15 and the guide plate 16 drive the two sets of side rotating seats 17 to move in opposite directions, and the guide rollers 18 on the two sets of side rotating seats 17 move laterally to match the width of the steel strip. This allows the two sets of guide rollers 18 to smoothly guide the steel strip through the guide sleeve 15 and the guide plate 16, so that the device can adapt to steel strips of different widths.

[0024] In other embodiments, a control box 6 is installed on the outer wall of the equipment base 1, a display panel 7 is installed on the control box 6, and a control button 8 is provided at the lower end of the display panel 7. The input terminals of the drive motor 4 and the servo motor 10 are electrically connected to the control box 6 through wires.

[0025] This design allows the display panel 7 on the control box 6 to display the pressure value in real time. Then, the parameters can be set by the control buttons 8 to control the servo motor 10 to precisely adjust the position of the guide roller 18 and the drive motor 4 to precisely control the speed, thereby achieving automated control, reducing human operation errors, and improving peeling accuracy.

[0026] In other embodiments, the thread directions on both sides of the bidirectional lead screw 11 are opposite;

[0027] With this design, when the bidirectional lead screw 11 rotates, the two sets of threaded sleeves 12 outside the two sets of bidirectional lead screws 11 can move synchronously in opposite directions or in opposite directions.

[0028] In other embodiments, the surface of the guide roller 18 is coated with a polyurethane elastic layer;

[0029] This design allows the polyurethane elastic layer to form a flexible contact surface on the guide roller 18, protecting the steel strip surface and preventing scratches.

[0030] In other embodiments, the outer walls of the top ends of the guide sleeve 15 and the guide plate 16 are polished, and the edges of the guide sleeve 15 and the guide plate 16 are rounded.

[0031] This design effectively reduces the friction on the surface of the steel strip, making it easier to guide the steel strip smoothly through the surfaces of the guide sleeve 15 and the guide plate 16.

[0032] In other embodiments, the outer wall of the guide plate 16 is fully fitted with the inner wall of the guide sleeve 15, and the guide plate 16 and the guide sleeve 15 are slidably connected.

[0033] This design ensures that the guide plate 16 and guide sleeve 15 can retract normally when the two sets of threaded sleeves 12 drive the guide plate 16 and guide sleeve 15 to move in opposite directions.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
