Description

Technical Field

[0001] This utility model belongs to the field of steel processing technology, specifically relating to an intelligent correction and detection device for rolling mills and a rolling mill. Background Technology

[0002] During strip rolling, strip misalignment frequently occurs, leading to problems such as strip edge damage, uneven thickness, and even equipment malfunction. Current technology lacks the capability for real-time detection of strip misalignment, resulting in delayed correction adjustments and difficulty in accurately controlling the adjustment range, which is detrimental to high-precision strip rolling. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide an intelligent strip deviation detection device for rolling mills. This device can detect the deviation of strip steel in real time, which is beneficial to improving the deviation correction accuracy and the rolling accuracy of strip steel.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A rolling mill intelligent deviation correction detection device includes a limiting component and a sensor. The limiting component includes a deflector and an elastic element. The deflector is disposed on one side of the rolling mill conveying channel, and one end of the deflector is rotatably connected to the mill frame. The deflector has a trigger part that protrudes and is arc-shaped towards one side of the rolling mill conveying channel. The elastic force of one end of the elastic element acts on the deflector. Under normal conditions, the trigger part corresponds to the strip deviation boundary. The sensor is used to detect the deflection amplitude of the deflector away from the rolling mill conveying channel to obtain the strip deviation situation.

[0006] In a preferred embodiment of this utility model, the elastic force of the elastic element acts on the side of the deflector that is away from the mill conveying channel, and corresponds to the triggering part;

[0007] The sensor is located on the side of the sway member away from the mill conveyor channel, and the sensing end of the sensor corresponds to the free end of the sway member. Here, the free end refers to the end of the sway member that is not connected to the mill frame.

[0008] In a preferred embodiment of the present invention, a boss is further provided on the frame; the two ends of the elastic element act on the boss and the deflector respectively.

[0009] A preferred embodiment of this utility model further includes a limiting block; the limiting block is disposed on the side of the swaying member close to the mill conveying channel. The limiting block can be directly fixed to the frame, and its main function is to limit the reset of the swaying member, preventing the swaying amplitude of the swaying member towards the mill conveying channel from being too large under the elastic force of the elastic element, thus affecting the normal conveying of the strip steel.

[0010] A preferred embodiment of this utility model further includes a plurality of guide wheels; each guide wheel is disposed on both sides of the mill conveying channel; along the conveying direction of the strip steel, each guide wheel is located behind the limiting assembly.

[0011] In a preferred embodiment of this utility model, the sensor includes a base and a rotation sensing component. The rotation sensing component includes a rotating element and a roller. One end of the rotating element is rotatably connected to the base, and the roller is rotatably disposed at the other end of the rotating element. The roller constitutes the sensing end of the sensor, and the roller contacts the side of the swaying element away from the mill conveying channel.

[0012] The sensor in this embodiment can refer to the prior art, and is designed to detect the swaying of the swaying component.

[0013] In a preferred embodiment of this utility model, the sensor is electrically connected to the control display screen of the rolling mill; when the sensor detects that the swaying member is swaying away from the conveying channel of the rolling mill, it generates a deviation signal and transmits the deviation signal to the control display screen, and the control display screen displays the corresponding deviation information after receiving the deviation signal.

[0014] Preferably, the sensor is electrically connected to the control system of the rolling mill; when the sensor detects that the swaying member is swaying away from the rolling mill conveying channel at a sway angle, it generates a deviation signal and transmits the deviation signal to the control system. After receiving the deviation signal, the control system sends an adjustment command to the power mechanism used to adjust the conveying direction of the strip steel to realize dynamic real-time deviation correction of the strip steel.

[0015] Another objective of this invention is to provide a rolling mill that includes the aforementioned intelligent deviation correction and detection device.

[0016] A rolling mill, including the intelligent deviation correction and detection device for the rolling mill.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model's intelligent strip deviation detection device for rolling mills, through the use of limit components and sensors, can effectively detect whether the strip is deviating in real time. This allows for real-time acquisition of the strip's conveying and operation status during processing, which is beneficial for accurately grasping deviation information and improving processing accuracy.

[0019] Specifically, if the strip deviates during operation, it will touch the trigger, causing the deflector to wobble. The sensor can then monitor this wobble in real time and provide timely feedback to the relevant equipment for correction and adjustment. When the strip resumes normal operation, it no longer exerts force on the trigger, and the deflector rotates and resets under the action of the elastic element. Attached Figure Description

[0032] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] See Figures 1-4 This embodiment discloses an intelligent rolling mill deviation correction detection device, including a limiting component, a sensor 3, and multiple guide wheels 5. The limiting component includes a deflector 1 and an elastic element 2; the deflector 1 is disposed on one side of the rolling mill conveying channel, and one end of the deflector 1 is rotatably connected to the frame. The deflector 1 is provided with a trigger part 101 that protrudes and is arc-shaped towards one side of the rolling mill conveying channel; the elastic force of one end of the elastic element 2 acts on the deflector 1. Under normal conditions, the trigger part 101 corresponds to the strip deviation boundary; the sensor 3 is used to detect the deflection amplitude of the deflector 1 away from the rolling mill conveying channel to obtain the strip deviation situation.

[0035] Furthermore, in this embodiment, the elastic force of the elastic element 2 acts on the side of the sway member 1 away from the mill conveyor channel, and corresponds to the trigger part 101. The sensor 3 is located on the side of the sway member 1 away from the mill conveyor channel, and the sensing end of the sensor 3 corresponds to the free end of the sway member 1. Here, the free end refers to the end of the sway member 1 that is not connected to the mill stand.

[0036] In this embodiment, the elastic element 2 can be a spring, or other components with elastic reset effect. In this embodiment, one end of the elastic element 2 is applied to the position corresponding to the trigger part 101, which helps to more stably and quickly rotate the sway member 1 towards the mill conveyor channel side, thereby achieving reset; in addition, the sensor 3 can also be placed near the free end of the sway member 1, making the whole structure more compact and easier to assemble.

[0037] In this embodiment, the side of the trigger part 101 away from the mill conveying channel can be set as a recessed structure, forming an integral part with the arc-shaped trigger part 101. The recessed structure also facilitates the positioning of the elastic element 2 and prevents the elastic element 2 from shifting. Alternatively, a recessed position adapted to the end of the elastic element 2 can be directly set on the side of the trigger part 101 away from the mill conveying channel, thereby improving the positional stability of the elastic element 2.

[0038] To facilitate the installation of the elastic element 2, a boss 4 is provided on the frame in this embodiment; the two ends of the elastic element 2 act on the boss 4 and the deflector 1, respectively. Figures 1-3 As shown, the boss 4 can be positioned relative to the trigger part 101, thus facilitating the installation of the elastic element 2. Furthermore, a cylinder can be installed on the side of the boss 4 facing the deflector 1, with a certain gap reserved between the cylinder and the deflector 1. The elastic element 2 can then be fitted onto the cylinder, thus enabling its installation.

[0039] Furthermore, in this embodiment, a limiting block 6 is also provided on the frame; the limiting block 6 is located on the side of the swaying member 1 near the mill conveying channel. The limiting block 6 can be directly fixed to the frame, and its main function is to limit the reset of the swaying member 1, preventing the swaying amplitude of the swaying member 1 towards the mill conveying channel from being too large under the elastic force of the elastic element 2, thus affecting the normal conveying of the strip steel. Furthermore, in this embodiment, the limiting block 6 can preferably be located near the free end of the swaying member 1, which makes the limiting of the swaying member 1 more effective; of course, the position of the limiting block 6 can be flexibly adjusted to limit the swaying of the swaying member 1 towards the mill conveying channel.

[0040] In this embodiment, the rotational connection between the oscillating component 1 and the frame can be implemented in different ways, such as bearing connection or sleeve connection, as long as the oscillating component 1 can rotate and oscillate.

[0041] In this embodiment, each guide wheel 5 is arranged on both sides of the mill conveying channel; along the conveying direction of the strip, each guide wheel 5 is located behind the limiting assembly. By setting the guide wheels 5, the position of the strip can be guided and adjusted, allowing the strip to run on the center line of the mill conveying channel, which helps to prevent deviation.

[0042] The sensor 3 in this embodiment includes a base and a rotation sensing component. The rotation sensing component includes a rotating element 302 and a roller 301. One end of the rotating element 302 is rotatably connected to the base, and the roller 301 is rotatably disposed at the other end of the rotating element 302. The roller 301 constitutes the sensing end of the sensor 3, and the roller 301 contacts the side of the sway member 1 away from the mill conveying channel. Thus, when the strip deviates during conveying, the strip will touch the trigger part 101 of the sway member 1, causing the sway member 1 to deviate to the side away from the mill conveying channel. At this time, the sway member 1 will also cause the rotation sensing component to rotate to the side away from the mill conveying channel, thereby triggering the sensor 3 and causing the sensor 3 to detect the strip deviating. Furthermore, the sensor 3 can also determine the deviation range of the strip by the rotation angle of the rotation sensing component, achieving accurate detection of strip deviation. The sensor 3 in this embodiment can refer to the prior art, and can detect the swaying of the swaying component 1 and its swaying amplitude. For example, it can be an angle sensor 3, a pressure sensor 3, etc. The strip deviation can be obtained by detecting the swaying angle of the swaying component 1, or the strip deviation can be calculated by measuring the pressure of the swaying component 1 on the sensor 3.

[0043] In this embodiment, sensor 3 can be electrically connected to the control display screen of the rolling mill and to the control system of the rolling mill. When sensor 3 detects that the swaying member 1 is swaying away from the rolling mill conveying channel at an angle, it generates a deviation signal and transmits the deviation signal to the control display screen. After receiving the deviation signal, the control display screen displays the corresponding deviation information. Alternatively, the deviation signal can be transmitted to the control system. After receiving the deviation signal, the control system issues an adjustment command to the power mechanism used to adjust the conveying direction of the strip steel to achieve dynamic real-time deviation correction of the strip steel.

[0044] This embodiment also discloses a rolling mill, including a rolling mill intelligent correction detection device, wherein the limiting component and sensor 3 in the rolling mill intelligent correction detection device can be optionally set on the O side of the rolling mill.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
