Description

Technical Field

[0001] This invention relates to the field of C-shaped steel production technology, and in particular to an intelligent control device and method for flexible roll bending of C-shaped steel. Background Technology

[0002] Flexible roll forming technology is a core and commonly used technology in the field of C-shaped steel roll forming. Combined with specialized flexible roll forming dies, it can effectively optimize forming accuracy and production efficiency, and is an important development direction for the C-shaped steel production industry. However, the domestic C-shaped steel production field is still dominated by traditional continuous roll forming processes, which use an integrated fixed structure for the roll mill. This structure lacks independent adjustment and adaptation capabilities. When producing C-shaped steel with different cross-sectional dimensions and specifications, manual disassembly, reassembly, and calibration of the rolls are required, along with repeated adjustments to forming parameters to match production needs. This not only consumes significant manpower and material resources but also leads to production interruptions and significantly extended specification changeover cycles, severely restricting the improvement of overall production efficiency and making it difficult to meet the demands of large-scale, multi-specification production.

[0003] Although some existing technologies have made discrete improvements to traditional C-shaped steel rolls, developing flexible roll bending dies that can adapt to various specifications, thus solving the limitation of traditional dies adapting to only one specification to some extent, the corresponding flexible roll bending units lack corresponding precise spatial movement mechanisms and intelligent control systems. In terms of precision control, the existing flexible roll bending units lack integrated real-time pressure sensing and compensation systems, making it impossible to accurately detect and adaptively adjust rolling force and roll gap position online. This leads to a heavy reliance on manual experience for repeated trials and adjustments when changing to different material specifications. This not only results in low adjustment accuracy and poor stability, but also prevents high-precision adjustment of the unit in both horizontal and vertical directions, easily causing product dimensional deviations (such as insufficient straightness), and significantly reduces production speed, making it difficult to fully utilize the multi-specification adaptability potential of flexible dies. Meanwhile, in terms of system architecture, the commonly used flexible roll bending units currently employ a single-frame, unit-based control mode, which has significant drawbacks. Each frame requires an independent control system, leading to redundant investment in hardware and software, and a significant increase in R&D and manufacturing costs. Furthermore, in the initial installation phase, each individual frame must be individually debugged and calibrated, greatly extending the R&D cycle, impacting production efficiency, and making it difficult to achieve efficient coordination between different passes through decentralized control, further restricting the improvement of overall forming accuracy and stability. Therefore, current flexible roll bending units still rely on manual operation for adjustment in the early stages, resulting in low levels of automation and intelligence, insufficient adjustment accuracy and stability, and a tendency to produce forming deviations, while also incurring extremely high R&D costs. This has become a key pain point restricting the industrialization and large-scale application of C-shaped steel flexible roll bending forming technology. Therefore, achieving precise spatial movement and intelligent control of flexible roll bending units has become an important issue that urgently needs to be addressed in the current industry development.

[0004] Therefore, this application designs an intelligent control device and method for C-shaped steel flexible roll bending to solve the above-mentioned technical problems. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 8 As shown, this embodiment provides an intelligent control device for flexible roll bending of C-shaped steel, including a roll bending mechanism and a control mechanism. The control mechanism is used to control the operation and adjustment of the roll bending mechanism. The roll bending mechanism includes a first roll pressing assembly and a second roll pressing assembly arranged sequentially along the production direction. A control mechanism is installed on the first roll pressing assembly and the second roll pressing assembly respectively, and adjusts the first roll pressing assembly and the second roll pressing assembly according to the production requirements of C-shaped steel. The control mechanism includes an electrically connected control component and an adjustment component. The adjustment component is drivenly connected to the first roller pressing component and the second roller pressing component, respectively. The control component adjusts the first roller pressing component and the second roller pressing component through the adjustment component.

[0022] This invention discloses an intelligent control device for flexible C-shaped steel roll bending, consisting of two core modules: a roll bending mechanism and a control mechanism. The control mechanism is responsible for the operation control and parameter adjustment of the roll bending mechanism, forming a collaborative "execution-control" architecture. The modular division of the roll bending mechanism and the control mechanism, and the independent setting of the two roll pressing components, make the equipment structure clear, facilitate maintenance and upgrades, and reserve expansion space for future expansion to include more roll pressing components and adapt to more complex forming requirements. The roll bending mechanism is arranged with a first roll pressing component and a second roll pressing component sequentially along the C-shaped steel production direction, forming the core execution unit for continuous roll bending forming, providing the foundation for multi-pass roll forming of C-shaped steel. The control mechanism allows for targeted adjustment of the two independently set roll pressing components, adapting to the production needs of different specifications of C-shaped steel without disassembling or replacing the rolls, thus solving the pain points of poor flexibility and cumbersome changeover in traditional continuous roll bending processes. The control mechanism comprises a control component and an adjustment component, which are electrically connected to transmit signals and issue commands. This "control component + adjustment component" electrical connection design, combined with the transmission connection between the adjustment component and the rolling assembly, ensures precise transmission and execution of control commands, reduces errors from manual adjustments, and improves the consistency and accuracy of C-shaped steel forming dimensions. The adjustment component establishes transmission connections with both the first and second rolling assemblies, forming a "control component - adjustment component - rolling assembly" power and signal transmission link. The control mechanism is independently installed on both the first and second rolling assemblies, integrating operation control and parameter adjustment functions. It can selectively adjust the two rolling assemblies individually or collaboratively according to the production needs of different C-shaped steel specifications, and can also adjust the two rolling assemblies separately without requiring complex mechanical adjustments during machine downtime. This shortens specification changeover time, reduces manual intervention costs, and significantly improves production efficiency. This invention designs a servo control system and a moving component 102 for a flexible roll bending unit, which enables the flexible roll bending unit to move left and right in space. At the same time, a servo control system is designed for the upper roll of the flexible roll bending unit, which enables the upper roll to move up and down.

[0023] In one embodiment of the present invention, the main purpose of the control mechanism is to adjust the first roller pressing assembly and the second roller pressing assembly. Whether the control mechanism is integrated or installed separately does not affect its control purpose. Those skilled in the art can adjust the layout of the control mechanism according to actual needs, and therefore all of these adjustments fall within the protection scope of this embodiment.

[0024] A further optimized scheme includes a first roller pressing assembly comprising a first flexible roller bending unit 1 and a second flexible roller bending unit 2, wherein the raw material is roller-bent between the first and second flexible roller bending units 1 and 2; adjusting components are respectively disposed on the first and second flexible roller bending units 1 and 2. The second roller pressing assembly comprises a third flexible roller bending unit 3 and a fourth flexible roller bending unit 4, wherein the raw material is roller-bent between the third and fourth flexible roller bending units 3 and 4; adjusting components are respectively disposed on the third and fourth flexible roller bending units 3 and 4. (See appendix) Figure 1 and attached Figure 2 As shown, the entire flexible roller bending machine is divided into four parts: the first flexible roller bending unit 1, the second flexible roller bending unit 2, the third flexible roller bending unit 3, and the fourth flexible roller bending unit 4. The parameters of each unit can be precisely adjusted according to the forming state of the raw material to adapt to the needs of different forming stages. The parameters of the first flexible roller bending unit 1, the second flexible roller bending unit 2, the third flexible roller bending unit 3, and the fourth flexible roller bending unit 4 can be adjusted separately without disassembling the equipment. The modular adjustment is convenient and flexible, further improving the product accuracy.

[0025] In one embodiment of the present invention, the adjustment method and principle of the second flexible roller bending unit 2, the third flexible roller bending unit 3, and the fourth flexible roller bending unit 4 are the same as those of the first flexible roller bending unit 1. The adjustment method of the first flexible roller bending unit 1 will be used for explanation and description in the following explanation.

[0026] Further optimizing the design, the first roller pressing assembly includes a base 101, on which three sets of moving components 102 are arranged. The moving components 102 are connected to a first drive module located within the base 101. The first flexible roller bending unit 1 and the second flexible roller bending unit 2 are respectively mounted on the moving components 102. The base 101 serves as the foundation of the device, fixing the equipment to the ground of the production plant to ensure the stability of the production process. Driven by a drive module, the moving components 102 adjust the horizontal position of the first flexible roller bending unit 1 and the second flexible roller bending unit 2, enabling flexible adjustment of the spacing between the units. This adapts to the production of C-shaped steel with different web lengths, improves equipment adaptability, and solves the problem that the traditional fixed layout of the units cannot adapt to the production of multiple specifications. Adjustment can be achieved without disassembly, making it more convenient for assembly line production.

[0027] Further optimizing the design, the first drive module includes a second lifting platform 104 and a second servo motor 105 mounted on the base 101. The output end of the second servo motor 105 is connected to the second lifting platform 104 for transmission. The second lifting platform 104 is used to drive the translation of the first flexible roll bending unit 1 and the second flexible roll bending unit 2. The combination of the second lifting platform 104 and the second servo motor 105 ensures stable and precise power output, providing reliable power support for the translation of the units. During operation, the second lifting platform 104 drives the first flexible roll bending unit 1 and the second flexible roll bending unit 2 to translate via the driving moving component 102, realizing automated control of the unit translation, replacing the traditional manual adjustment method, significantly shortening the specification changeover time, improving production efficiency, and reducing labor costs.

[0028] Further optimizing the design, the moving component 102 includes a transverse guide rail 1021 arranged on the base 101. Symmetrically arranged sliders 1022 are slidably mounted on the transverse guide rail 1021. A longitudinal base plate 103 is fixed to the upper side of the two sliders 1022 on the same side. The first flexible roll bending unit 1 and the second flexible roll bending unit 2 are respectively mounted on the two longitudinal base plates 103. The transverse guide rail 1021 is arranged on the base 101, and the sliders 1022 cooperate with the transverse guide rail 1021 to ensure the stability and guiding accuracy of the unit's translation process, avoiding forming errors caused by unit offset during translation. The sliders 1022 are used to connect to the longitudinal base plates 103, providing a stable installation foundation for the units, while also achieving a reliable connection between the units and the moving component 102, improving the overall structural stability and service life of the equipment.

[0029] The second lifting platform 104 includes a horizontal lifting platform 1041, which is positioned between the first flexible roller bending unit 1 and the second flexible roller bending unit 2. The horizontal lifting platform 1041 is connected to an extension rod 1042 via a coupling 1043, and the extension rod 1042 is connected to a second servo motor 105 via a reducer 106. Several horizontal lifting platforms 1041 are arranged on the base 101, with their output ends connected to the longitudinal base plate 103, the first flexible roller bending unit 1, or the second flexible roller bending unit 2. They can drive the first flexible roller bending unit 1 or the second flexible roller bending unit 2 to move and adjust according to adjustment requirements. The extension rod 1042, which is driven to the input end of the horizontal lifting platform 1041, is arranged outside the flexible roller bending unit and is used to connect the horizontal lifting platform 1041 and the servo motor to realize power transmission and provide adjustment power for the horizontal lifting platform 1041.

[0030] In one embodiment of the present invention, the second elevator 104 further includes a plurality of couplings 1043 for connecting the horizontal elevator 1041, the extension rod 1042 and the servo motor.

[0031] In one embodiment of the present invention, during specific adjustment, the second servo motor 105, after speed adjustment via the reducer 106, transmits power to the horizontal lifting platform 1041 through the extension rod 1042. When the output end of the horizontal lifting platform 1041 moves left and right, it pushes the slider 1022 connected to the lower part of the longitudinal base plate 103 to move left and right, thereby realizing the left and right movement of the longitudinal base plate 103 and the flexible roller bending unit on the longitudinal base plate 103. When the flexible roller bending unit reaches the designated position, it is fixed by locking the second servo motor 105.

[0032] Further optimizing the scheme, the adjustment component also includes a first servo motor 6 electrically connected to the control component. The output end of the first servo motor 6 is driven by a first lifting mechanism 5. The output end of the first lifting mechanism 5 is driven by a bushing 7 sleeved on the flexible roll. The first lifting mechanism 5 drives the bushing 7 to move. The first servo motor 6 is arranged on the outside of the upper roll of the flexible roll mill. The first lifting mechanism 5 is arranged on the upper side of the upper roll to connect to the first servo motor 6 and provide power to the first lifting mechanism 5. The flexible roll passes through the bushing 7, and the bushing 7 is connected to the first lifting mechanism 5 to form a control closed loop. This can drive the bushing 7 to move, thereby driving the upper roll of the flexible roll bending mill to move longitudinally, while protecting the roll, avoiding damage to the roll during adjustment, and extending the service life of the equipment.

[0033] In one embodiment of the present invention, the number of first servo motors 6 corresponds to the number of first flexible roller bending unit 1, second flexible roller bending unit 2, third flexible roller bending unit 3 and fourth flexible roller bending unit 4, respectively realizing the adjustment of different roller bending units.

[0034] Further optimizing the design, the first lifting machine 5 includes a downward lifting machine 501 that is driven and connected to the first servo motor 6. The output end of the downward lifting machine 501 is driven and connected to the bushing 7 via a pressure sensor. The downward lifting machine 501 is arranged on the upper side of the upper roll of the flexible roll bending unit and is driven and connected to the first servo motor 6 to provide power for the roll lifting and lowering; the pressure sensor 502 is arranged at the lower end of the downward lifting machine 501 and fixed on the bushing 7 to assist in the positioning of the bushing 7.

[0035] In one embodiment of the present invention, during specific adjustments, an intelligent control device is installed in each pass of the flexible roll bending unit. When producing C-shaped steel with different flange heights, the flexible roll bending unit needs to move up and down. At this time, the first servo motor 6 transmits power to the lower pressure lifting machine 501 through the coupling 1043, and the lower pressure lifting machine 501 converts the power into longitudinal pressure. The pressure transmitted by the lower pressure lifting machine 501 is positioned and fed back by the pressure sensor 502, which drives the bushing 7 to move up and down, and then the bushing 7 drives the upper roll of the flexible roll bending unit to move up and down. When the upper roll of the flexible roll bending unit reaches the designated position, it is fixed by locking the first servo motor 6, thereby achieving the purpose of producing C-shaped steel with different web lengths.

[0036] This invention also discloses an intelligent control method for flexible roll bending of C-shaped steel, comprising the following steps: The adjustment strategy for the equipment is planned according to the required C-shaped steel specifications, and adjustment commands are input through the control component. Based on the target specifications of the C-shaped steel to be produced, parameter information is entered through the human-machine interface of the control component. The control component has a built-in specification-adjustment parameter mapping database, which, combined with the flexible roll bending process model, automatically generates an appropriate adjustment strategy. This strategy clarifies the horizontal movement distance threshold for each flexible roll bending unit, as well as the vertical movement height threshold, adjustment sequence, and synchronization accuracy requirements for the upper rolls of each unit. Simultaneously, it plans the feedback threshold for pressure sensor 502 and the triggering conditions for motor seizure. After the control component starts, it automatically performs initial state detection on the equipment, using the position sensors of each unit to provide feedback on the current vertical position of the rolls. The detection data is compared with the initial calibration benchmark value of the equipment. If a deviation exists, the control component automatically issues a fine-tuning command, resetting each unit and upper roll to the standard initial position through the adjustment component, ensuring a unified adjustment benchmark.

[0037] The adjustment component corresponding to the first roller pressing assembly is activated to adjust the first roller pressing assembly, enabling it to translate horizontally and vertically to match the corresponding C-shaped steel specification. The control component sends a horizontal adjustment command to the second servo motor 105 corresponding to the first roller pressing assembly. After the second servo motor 105 is activated, its speed is adjusted by the reducer 106, and it drives the extension rod 1042 of the horizontal lifting platform 1041 through the coupling 1043, thereby driving the horizontal lifting platform 1041 to run. The horizontal lifting platform 1041 generates a horizontal thrust, pushing the moving component 102 on the base 101 to slide along the transverse guide rail 1021. The slider 1022 drives the upper longitudinal base plate 103 to move synchronously, ultimately realizing the horizontal translation of the first roller pressing assembly. During the adjustment process, the control component receives the position feedback signal of the moving component 102 in real time. When the first roller pressing assembly moves to the target position, the control component issues a command to lock the second servo motor 105, completing the horizontal positioning. Simultaneously, the control component sends a vertical adjustment command to the first servo motor 6 corresponding to the first roller pressing component; the first servo motor 6 transmits power to the lower pressing lift 501 through the coupling 1043, and the lower pressing lift 501 converts the rotational power into longitudinal pressure; the pressure is detected and fed back by the pressure sensor 502, and the control component precisely adjusts the extension and retraction of the lower pressing lift 501 according to the pressure signal, driving the bushing 7 to move in the vertical direction, thereby pulling the upper roller of the flexible roller bending unit to move up and down; when the pressure value fed back by the pressure sensor 502 reaches the preset threshold, the control component commands the first servo motor 6 to lock, completing the vertical positioning of the upper roller of the first roller pressing component.

[0038] The adjustment component corresponding to the first roller pressing assembly is activated to adjust the second roller pressing assembly, enabling it to translate horizontally and vertically to match the corresponding C-shaped steel specification. The second roller pressing assembly uses the same control logic as the first roller pressing assembly for horizontal adjustment. The control component sends a horizontal adjustment command to the second servo motor 105 corresponding to the second roller pressing assembly. Through the transmission link of "servo motor - reducer 106 - coupling 1043 - horizontal lifting mechanism 1041 - moving component 102", the second roller pressing assembly is driven to move horizontally along the transverse guide rail 1021. The control component compares the actual position of the second roller pressing assembly with the target position in real time. Positioning is ensured so that the spacing between the second and first roller pressing assemblies is adapted to the C-shaped steel forming process. After reaching the target position, the second servo motor 105 is locked in place. Simultaneously, using the transmission mechanism of the vertical adjustment of the first roller pressing assembly, the control assembly sends a vertical adjustment command to the first servo motor 6 corresponding to the second roller pressing assembly. Through the coordinated action of the lower lifting machine 501, pressure sensor 502, and bushing 7, the upper roller of the second roller pressing assembly is driven to move up and down. Combined with the flange height requirements of the C-shaped steel to be produced, precise positioning is achieved through real-time feedback from the pressure sensor 502. After reaching the target position, the first servo motor 6 is locked in place, completing the vertical adjustment of the second roller pressing assembly.

[0039] The C-shaped steel is flexibly rolled. After adjustment, the accuracy is checked. Once the accuracy check is passed, the control component issues a processing start command. The raw material enters the first and second roller pressing components in sequence. Under the coordinated rolling action of the first and second roller pressing components, the flexibly rolled steel is formed. During the processing, the control component continuously monitors the operating status of each servo motor, the feedback data of the pressure sensor 502, and the unit position signal. If parameter drift or equipment abnormality occurs, an early warning is issued and processing is suspended. Production can only resume after the fault is eliminated and recalibrated.
