Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel processing technology, and specifically discloses a special steel intelligent straightening system. Background Technology
[0002] Special steel straightening, as a subsequent finishing process in steel rolling production, plays a crucial role in improving product quality. However, current special steel straightening equipment cannot automatically adjust the roller spacing based on the curvature of the special steel plate surface. This requires manual adjustment and measurement of the roller spacing, resulting in a large workload during the straightening process and hindering intelligent control.
[0003] Furthermore, after exiting the rolling mill, special steel plates undergo a long cooling and conveying process. During this time, foreign matter and impurities inevitably accumulate on the surface of the steel plates. Traditionally, this is removed by air blowing before the steel plates enter the straightening machine to prevent damage to the straightening rolls. However, air blowing requires a complex compressed gas auxiliary system, and the high temperature on the surface of the special steel plates after exiting the rolling mill causes these impurities to adhere strongly, making it difficult to ensure complete removal using air blowing. Therefore, addressing the technical problems and shortcomings of existing special steel straightening systems, this application proposes an intelligent special steel straightening system that effectively solves the aforementioned problems. Utility Model Content
[0004] This utility model mainly provides a special steel intelligent straightening system, which realizes intelligent control and adjustment in the straightening process of special steel plates, and can effectively remove impurities on the surface of special steel plates, avoiding damage to the straightening rollers caused by foreign matter and impurities.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] A special steel intelligent straightening system includes a feeding unit, a straightening unit, and a control box. The feeding unit and the straightening unit are arranged side by side on the base. A CCD camera and a feeding laser ranging component are respectively arranged above the left and right sides of the feeding unit. A steel plate surface cleaning mechanism is arranged between the CCD camera and the feeding laser ranging component.
[0007] The correction unit includes a housing with a row of support rollers at the bottom and a correction roller seat above the support rollers. A correction roller located directly above the support rollers is rotatably connected to the correction roller seat, and a correction motor extending out of the housing is connected to the side end of the correction roller. A correction lifting hydraulic cylinder is installed on the top of the housing, and a laser rangefinder sensor for measuring the distance to the correction roller seat is also installed on the top of the housing.
[0008] As a further provision of the above solution, the steel plate surface cleaning mechanism includes a first bracket mounted on the feeding unit. An adjusting hydraulic cylinder is mounted on the upper end of the first bracket, and a V-shaped brush bar is connected to the lower end of the adjusting hydraulic cylinder. Brush filaments that act on the surface of the steel plate are mounted on the lower surface of the brush bar.
[0009] As a further feature of the above scheme, the midpoint of the brush bar is located on the transverse center line of the feeding unit, and impurity collection ports are provided at the lower ends of the feeding unit located at the front and rear ends of the brush bar.
[0010] As a further provision of the above scheme, the feeding unit includes a conveyor seat, on which a row of conveyor rollers are rotatably connected, and the ends of the conveyor rollers are connected to a conveyor motor.
[0011] As a further feature of the above scheme, a clamping and centering mechanism is provided in the transport seat located on the left side of the CCD camera. The clamping and centering mechanism includes a sliding rod and a bidirectional screw that are parallel to each other and located at the lower end of the transport seat. A screw motor is provided at one end of the bidirectional screw. Both the front and rear ends of the bidirectional screw are threadedly connected to screw hole blocks. The upper ends of the two screw hole blocks are rotatably connected to clamping rollers that extend vertically upward above the transport rollers. The side ends of the screw hole blocks are connected to sliding hole blocks that interact with the sliding rod.
[0012] As a further provision of the above scheme, a second bracket and a third bracket are respectively provided on the left and right sides of the steel plate surface cleaning mechanism. The CCD camera is installed on the upper end of the second bracket, and the feeding laser ranging component consists of at least two laser rangefinders arranged side by side.
[0013] As a further feature of the above solution, a strip is provided on the upper right side of the chassis, and a discharge laser ranging component for detecting the corrected steel plate is provided on the strip. The discharge laser ranging component consists of at least two laser rangefinders arranged side by side.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. The special steel intelligent straightening system disclosed in this patent can detect the flatness of the steel plate surface online through the feeding laser ranging component before the straightening process and feed it back to the controller. Then the controller can adjust the distance between the support roller and the straightening roller in real time and accurately, so that the straightening adjustment process is fully automated. This not only reduces the adjustment frequency of on-site personnel, but also improves the processing efficiency of the special steel straightening system and increases production efficiency.
[0016] 2. This patent also uses a CCD camera to detect foreign objects and impurities on the surface of the special steel plate before correction. When foreign objects and impurities are detected, a cleaning method using brush strips and steel bristles is used to effectively remove the foreign objects and impurities that have fallen on the surface of the steel plate. Compared with the traditional air blowing cleaning method, this method not only has lower equipment manufacturing and operating costs, but also effectively removes some firmly attached foreign objects and impurities, effectively ensuring the long-term stable operation of the correction unit.

[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.
[0022] Example 1
[0023] Example 1 discloses a special steel intelligent straightening system, as shown in the attached figure. Figure 1-4 The main body of the system includes a base box 4, a feeding unit 1, a straightening unit 2, and a control box 3. The feeding unit 1 and the straightening unit 2 are arranged side by side on the upper surface of the base box 4. The control box 3 is located on the front side of the base box 4, and a corresponding SIEMENS S7-1500 series controller and image processing module are installed inside the control box 3. The controller is equipped with multiple signal input interfaces and signal output interfaces.
[0024] In the specific design, the feeding unit 1 includes a conveyor seat 101, on which a row of conveyor rollers 102 are rotatably connected, and the ends of the conveyor rollers 102 are connected to a conveyor motor 103. The speed of the conveyor motor 103 can be regulated by the controller inside the control box 3.
[0025] A CCD camera 5 and a feeding laser ranging component 6 are respectively installed on the upper left and right sides of the feeding unit 1. Specifically, a second support 501 and a third support 601 span across the conveyor base 101, with the CCD camera 5 mounted on the upper end of the second support 501. The feeding laser ranging component 6 consists of a row of laser rangefinders mounted on the third support 601. These rangefinders measure distances at different longitudinal positions on the steel plate surface, and the flatness of the steel plate surface can be determined through linear fitting. When the special steel plate to be corrected moves directly under the second support 501 and the third support 601, the CCD camera 5 first photographs its surface, then the image processing module and controller determine whether there are foreign matter or impurities on the surface of the special steel plate, and finally the feeding laser ranging component 6 determines the flatness of its surface.
[0026] A steel plate surface cleaning mechanism 7 is located between the CCD camera 5 and the feed laser ranging component 6. Specifically, the steel plate surface cleaning mechanism 7 includes a first support 701 spanning across the conveyor seat 101. An adjusting hydraulic cylinder 702 is located at the upper end of the first support 701. A V-shaped brush strip 703 is connected to the lower end of the adjusting hydraulic cylinder 702. Brush filaments 704, which act on the steel plate surface, are then provided on the lower surface of the brush strip 703. The brush filaments 704 are preferably made of hard material, specifically steel bristles, to effectively remove foreign matter and impurities adhering to the surface of the special steel plate. In addition, the midpoint of the brush bar 703 in this embodiment 1 is located on the transverse center line of the feeding unit 1, and the lower end of the conveying seat 101 located at the front and rear ends of the brush bar 703 is provided with an impurity collection port 100. Through the above specific design, when foreign impurities on the surface of the special steel plate are acted upon by the brush filaments 704, they can move to both sides and eventually be discharged from the front and rear ends of the special steel plate and fall into the impurity collection port 100 for collection.
[0027] In this embodiment 1, the straightening unit 2 includes a housing 201. A row of support rollers 202 is arranged at the lower end of the housing 201, and these support rollers 202 are set at the same height as a row of conveying rollers 102 in the feeding unit 1, allowing the special steel plate to be smoothly conveyed onto the support rollers 202. A straightening roller seat 203 is arranged above the row of support rollers 202. A straightening roller 204 located directly above the support rollers 202 is rotatably connected to the straightening roller seat 203, and a straightening motor 205 extending out of the housing 201 is connected to the side end of the straightening roller 204. Similarly, the straightening motor 205 can also be frequency-controlled by a controller. A straightening lifting hydraulic cylinder 206 is arranged at the top of the housing 201, and a laser rangefinder sensor 207 for measuring the distance to the straightening roller seat 203 is also arranged at the top of the housing 201. In addition, a strip-shaped opening for extending the straightening roller 204 is provided on the side of the housing 201, so that the straightening motor 205 can move up and down along the strip-shaped opening without obstruction during the up and down adjustment of the straightening roller seat 203.
[0028] To prevent the special steel plate from shifting before straightening, a clamping and centering mechanism 8 is provided in the conveyor seat 101 located to the left of the CCD camera 5. Specifically, the clamping and centering mechanism 8 includes a sliding rod 801 and a bidirectional screw 802, which are parallel to each other and located at the lower end of the conveyor seat 101. A screw motor 803 is then provided at one end of the bidirectional screw 802. Screw holes 804 are threadedly connected to both ends of the bidirectional screw 802. Clamping rollers 805, extending vertically upwards above the conveyor roller 102, are rotatably connected to the upper ends of both screw holes 804. A sliding block 806, which interacts with the sliding rod 801, is also connected to the side end of the screw holes 804. Through the design of the clamping and centering mechanism 8, when the special steel plate moves past the front and rear clamping rollers 805, the two clamping rollers 805 can move closer to each other under the combined action of the screw motor 803, the bidirectional screw 802 and the screw hole block 804, thereby clamping and centering the passing special steel plate for transport.
[0029] In this embodiment 1, a strip 208 is also provided on the upper right side of the chassis 201. The strip 208 is equipped with a discharge laser ranging component 9 for detecting the straightened steel plate. Specifically, the discharge laser ranging component 9 and the feed laser ranging component 6 have the same structure, both consisting of a row of spaced laser rangefinders, and both used to determine the surface flatness of the special steel plate. Finally, in this embodiment 1, the discharge laser ranging component 9, the feed laser ranging component 6, and the laser ranging sensor 207 are all connected to the signal input terminal of the controller inside the control box 3. Furthermore, the image processed by the CCD camera is also connected to the controller inside the control box 3. In addition, the adjusting hydraulic cylinder 702 and the straightening lifting hydraulic cylinder 206 in the steel plate surface cleaning mechanism 7 are also connected to the signal output terminal of the controller inside the control box 3.
[0030] In the operation of the special steel intelligent straightening system disclosed in Embodiment 1, the feeding unit 1 is used to receive the special steel plate after upstream rolling. After the special steel plate enters the feeding unit 1, it is first conveyed and corrected by the clamping and centering mechanism 8. After correction, the CCD camera detects foreign impurities on its surface. When foreign impurities are found on the surface, the hydraulic cylinder 702 is controlled to extend, thereby pushing the brush 703 downward, so that the brush filaments 704 on the lower surface of the brush 703 come into contact with the surface of the special steel plate, thereby cleaning and removing foreign impurities. After cleaning, the feeding laser ranging component 6 detects the flatness of the special steel plate surface.
[0031] When the special steel plate enters the straightening unit 2, the controller will control the downward distance of the straightening roller seat 203 and the straightening roller 204 in real time according to the data measured by the feeding laser ranging component 6, so as to ensure that the special steel plate can achieve the preset effect after being processed by the support roller 202 and the straightening roller 204. Finally, the surface flatness of the straightened special steel plate can be detected and judged by the discharge laser ranging component 9, thereby verifying the straightening effect.
[0032] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
