Description

Technical Field

[0001] This utility model relates to the technical field of metal strip processing equipment, specifically a guide device for preventing deviation during rolling of metal strip. Background Technology

[0002] In the field of metal strip roll forming, precise control of the strip's trajectory is a core element in ensuring product quality and production efficiency. Metal strip needs to be rolled continuously and stably through multiple sets of rolls. However, in actual production, the strip is prone to deviation due to factors such as incoming strip deviation (e.g., width and thickness fluctuations), roll system installation accuracy, and equipment vibration.

[0003] Existing anti-deviation guiding devices have significant drawbacks: most can only constrain the strip in a single dimension (such as width or thickness), making it difficult to comprehensively limit strip deviation when facing complex working conditions (such as strip shifting to the sides or tilting upwards); some devices rely on manual adjustment, which is cumbersome, slow to respond, and cannot meet the needs of automated production lines for rapid and precise control. Therefore, those skilled in the art have provided an anti-deviation guiding device for rolling metal strip to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a guide device for preventing deviation during rolling of metal strip, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A guide device for preventing deviation during rolling of metal strip includes a first guide rail, a second guide rail, a first servo motor, and a second servo motor. The first servo motor is located on the left side of the first guide rail and is fixedly mounted on the first guide rail. A bidirectional lead screw is fixedly connected to the power output end of the first servo motor and is rotatably connected to the first guide rail. Two sliders are threadedly connected to the bidirectional lead screw, and each slider is provided with a second guide rail at its upper end. The second guide rail is fixedly connected to the slider. A threaded rod is rotatably connected to each second guide rail, and a second slider is threadedly connected to each threaded rod. A lifting plate is fixedly connected to one side of each second slider.

[0007] As a further embodiment of this utility model: a sliding groove is provided at the upper end of the guide rail, wherein the slider is locked in the sliding groove, a base plate is provided at the lower end of the guide rail, wherein the base plate is fixedly connected to the guide rail, and two support plates are provided at the upper end of the guide rail, wherein the support plates are fixedly connected to the guide rail.

[0008] As a further embodiment of this utility model: a servo motor 2 is provided on the right support plate of the guide rail 1, wherein the servo motor 2 is fixedly installed on the right support plate, and a rotating shaft is fixedly connected to the power output end of the servo motor 2, wherein the rotating shaft is rotatably connected to the support plate.

[0009] As a further embodiment of this utility model: a plurality of limiting strips are provided on the outer wall of the rotating shaft, wherein the limiting strips are fixedly connected to the rotating shaft, and a sliding groove is provided on each of the guide rails, wherein the slider is engaged in the sliding groove, and a fixing plate is provided on the upper end of each of the guide rails, wherein the fixing plate is fixedly connected to the guide rail, and a rotating cylinder is rotatably connected to each of the fixing plates, wherein the rotating cylinder slides on the rotating shaft, and a plurality of limiting grooves are provided on the inner wall of each of the rotating cylinders, wherein the limiting strip is engaged in the limiting groove.

[0010] As a further improvement of this utility model: a main bevel gear is provided on the outer wall of the rotating cylinder, wherein the main bevel gear is fixedly connected to the rotating cylinder, and a driven bevel gear is fixedly connected to the upper end of the threaded rod, wherein the driven bevel gear and the main bevel gear are meshed together.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Width Adaptive Adjustment: Driven by a servo motor, a bidirectional lead screw rotates, causing slider one and guide rail two to move synchronously towards the center, quickly adjusting the distance between the two guide rails. This allows it to adapt to metal strips of different widths without the need to change equipment or frequently adjust manually. Compared to traditional fixed-spacing guide devices, it has stronger adaptability and more efficient adjustment, ensuring the strip runs in the center from the width dimension and preventing deviation.

[0013] 2. Flexible thickness adjustment: The servo motor drives the threaded rod through the rotating shaft, limit bar, and rotating cylinder, and the main-slave bevel gears to make the slider and lifting plate rise and fall precisely. This can be adjusted in real time according to the thickness of the strip, and form a three-dimensional limiting space with the guide rail to constrain the displacement of the strip thickness direction and prevent the strip from tilting upward due to vibration, thus achieving multi-dimensional anti-deviation.

[0014] 3. Multi-dimensional collaborative anti-deviation: The width adjustment and thickness limit functions are independently controlled by two sets of servo motors, and are also based on deep collaboration of mechanical structure to form a "planar + three-dimensional" all-round constraint system. Compared with single-direction anti-deviation devices, it can more accurately correct the deviation of strip running, adapt to complex rolling conditions, and improve the product accuracy after rolling of metal strip.

[0015] 4. High degree of automation: From width adaptation to thickness limit, the entire process is driven by servo motors and linked by mechanical structures, eliminating the need for manual adjustment, reducing operational intensity, minimizing human intervention errors, meeting the needs of modern industrial automated production, and helping metal strip rolling production lines improve quality and efficiency.
