It should be noted that the concepts of "first", "second", etc. mentioned in the present invention are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0041] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0042] In view of the problems existing in the above-mentioned related technologies, such as Figure 1 As shown, a wide width aluminum alloy cold-rolled sheet coil production system provided by an embodiment of the present invention comprises an unwinder 1, a six-roller irreversible rolling mill 3, two circular shears 4 and a coiler 6 which are sequentially arranged along the traveling direction of the conveyor belt;

[0043] The uncoiler 1 is used for unwinding the aluminum alloy material;

[0044] The six-roll irreversible rolling mill 3 is used to roll the aluminum alloy material to obtain an initial alloy cold-rolled sheet;

[0045] The two circular shears 4 are respectively located on both sides of the conveyor belt, and are used to perform edge trimming on the initial alloy cold-rolled sheet to obtain the final alloy cold-rolled sheet;

[0046] The coiler 6 is used to coil the final alloy cold-rolled sheet to obtain a wide width aluminum alloy cold-rolled sheet coil.

[0047] Specifically, when generating wide-width aluminum alloy cold-rolled sheet coils, the coiled aluminum alloy material first enters the unwinding machine 1 for unwinding, then enters the six-roll irreversible rolling mill 3 for rolling, and then enters the disc shears 4 on both sides of the conveyor belt for trimming, that is, the disc shears 4 on the operating side and the transmission side. The disc shears 4 on both sides can achieve symmetrical shear force balance to meet the uniform trimming requirements of wide sheets (sheets with a width of >2000mm), and then enter the coiler to be rolled into wide-width aluminum alloy cold-rolled sheet coils. For passes that do not require trimming, it is only necessary to adjust the opening degree of the disc shear 4 so that the shear blade of the disc shear is separated from the coil, so that no trimming is performed. The disc shear 4 adopts a cantilever knife box structure, in which an upper blade and a lower blade are arranged. The cutting edges of the upper blade and the lower blade face the forward direction of the initial alloy cold-rolled plate. Therefore, after the initial alloy cold-rolled plate enters the two disc shears 4 on both sides respectively, the two disc shears 4 shear the two sides of the initial alloy cold-rolled plate respectively through their respective upper blades and lower blades. The disc shear 4 adopts a power threading and passive shearing working mode. Power threading refers to the process of realizing the strip (i.e., the initial alloy cold-rolled plate) passing through the disc shear 4 through a motor drive. Power threading can ensure that the strip can enter the disc shear quickly and smoothly, reducing the threading time. Passive shearing means that during the normal shearing process, the disc shear 4 does not actively provide shearing power, but relies on the tension provided by subsequent equipment (such as a coiler) to complete the shearing. Passive shearing simplifies the shearing process and improves the overall work efficiency. The AC variable frequency motor of the disc shear 4 drives the lower blade shaft of the lower blade through the ball cage coupling and the overrunning clutch. The AC variable frequency motor provides shearing power when threading the belt. During normal shearing, the overrunning clutch disengages the power to realize the conversion between pulling shear and power shear, that is, converting to passive pulling shear.

[0048] In this embodiment, the aluminum alloy material is unrolled by the unwinding machine 1, which can provide a stable feed for the subsequent process, and then the aluminum alloy material is rolled by the six-roll irreversible rolling mill 3 to obtain an initial alloy cold-rolled plate that meets the requirements, and then the initial alloy cold-rolled plate is trimmed by two disc shears 4 arranged on both sides of the conveyor belt to remove edge defects such as burrs and flash, etc., to ensure the dimensional accuracy and quality of the final product, and obtain the final alloy cold-rolled plate, and finally the final alloy cold-rolled plate is re-rolled into a coil form by the coiler 6, which can be convenient for storage and transportation. By arranging the two disc shears 4 on both sides of the conveyor belt and between the six-roll irreversible rolling mill 3 and the coiler 6, additional steps such as coil transfer can be reduced during the trimming process, and uninterrupted continuous operation can be achieved, thereby improving the overall production efficiency.

[0049] Optionally, each of the circular shears 4 comprises an upper blade, a lower blade, an overlap amount monitoring module and an automatic control module, and the automatic control module is respectively connected to the upper blade, the lower blade and the overlap amount monitoring module;

[0050] The overlap monitoring module is used to monitor the current overlap between the upper blade and the lower blade;

[0051] The automatic control module is used to determine the rated overlap amount according to the material parameters of the initial alloy cold-rolled sheet, and adjust the actual overlap amount of the upper blade and the lower blade according to the rated overlap amount and the current overlap amount.

[0052] Specifically, the disc shear 4 includes an upper blade, a lower blade, an overlap monitoring module and an automatic control module. The upper blade and the lower blade are arranged in a cantilevered blade box, with the cutting edge facing the forward direction of the initial alloy cold-rolled plate, and the upper blade and the lower blade are provided with corresponding eccentric sleeves and worm gear pairs. The AC frequency conversion motor of the disc shear 4 drives the worm gear pair to move, so that the upper and lower eccentric sleeves rotate, thereby controlling the upper blade and the lower blade to perform shearing action. The material parameters of the initial alloy cold-rolled sheet include parameters such as hardness, thickness and material. The overlap monitoring module can use high-precision displacement measurement tools, such as grating rulers or magnetic rulers, to measure the overlap of the upper and lower blades of the disc shear 4 in real time. When the material parameters of the initial alloy cold-rolled sheet, i.e., hardness, thickness and material parameters, change, the automatic control module determines the rated overlap corresponding to the material parameters of the initial alloy cold-rolled sheet according to the process standards, and adjusts the actual overlap of the upper and lower blades by driving the eccentric sleeve to rotate or adjusting the position of the screw nut according to the rated overlap and the current overlap. For example, for the initial alloy cold-rolled sheet with a larger thickness, the overlap needs to be increased to ensure sufficient shearing force; for the initial alloy cold-rolled sheet with a smaller thickness, the overlap needs to be reduced to avoid excessive shearing that causes the quality of the aluminum plate edge to decrease. For example, after the shear blade overlap is adjusted, the brake on the gear motor is used to ensure that the overlap remains unchanged. When the disc shear 4 is running, an absolute encoder can also be used to detect the overlap of the disc shear 4.

[0053] Optionally, the circular shear 4 further comprises a pressure sensor, and the pressure sensor is respectively connected to the upper blade, the lower blade and the automatic control module;

[0054] The pressure sensor is used to monitor the shear force data of the upper blade and the lower blade;

[0055] The automatic control module is also used to control the operation of the upper blade and the lower blade according to the shear force data.

[0056] Specifically, the pressure sensor is installed on the blade shaft or transmission mechanism of the disc shear 4 to monitor the shear force data of the upper blade and the lower blade in real time, and feeds the shear force data back to the automatic control module. When the shear force data exceeds the limit, an alarm is triggered or the machine is automatically shut down.

[0057] Optionally, at least one tension sensor is provided on the conveyor belt between the uncoiler 1 and the circular shear 4, and the automatic control module is respectively connected to at least one tension sensor and the uncoiler 1;

[0058] The tension sensor is used to monitor the tension data of the aluminum alloy material and the initial alloy cold-rolled sheet;

[0059] The automatic control module is also used to control the unwinding tension of the unwinding machine 1 according to the tension data and the shear force data.

[0060] Specifically, at least one tension sensor is provided on the conveyor belt between the uncoiler 1 and the disc shear 4 to monitor the tension data of the aluminum alloy material and the initial alloy cold-rolled plate in real time. When a change in the tension data is detected, or a change in the shear force data is detected, the changed tension data or shear force data is fed back to the automatic control module. The automatic control module adjusts the uncoiling tension by adjusting the motor torque or braking torque of the uncoiler 1. For example, when the shear force of the disc shear 4 increases, the automatic control module automatically increases the uncoiling tension so that the initial alloy cold-rolled plate maintains an appropriate tension when entering the disc shear, thereby preventing the initial alloy cold-rolled plate from slipping or wrinkling during the shearing process, thereby effectively reducing the risk of damage to the initial alloy cold-rolled plate.

[0061] Optionally, the circular shear 4 further comprises a non-contact distance measuring sensor, and the non-contact distance measuring sensor is connected to the automatic control module;

[0062] The non-contact distance measuring sensor is used to monitor the current side clearance data of the upper blade and the lower blade;

[0063] The automatic control module is used to determine the rated side clearance data according to the material parameters of the initial alloy cold-rolled sheet, and to adjust the actual side clearance data of the upper blade and the lower blade according to the rated side clearance data and the current side clearance data.

[0064] Specifically, the non-contact distance measurement sensor can adopt a laser displacement sensor or an ultrasonic sensor and other sensors, and be installed in the vicinity of the upper blade and the lower blade to monitor the current side clearance data between the upper blade and the lower blade in real time. When the material parameters of the initial alloy cold-rolled sheet change, the automatic control module determines the rated side clearance data corresponding to the material parameters, and based on the rated side clearance data and the current side clearance data, the relative position of the upper blade and the lower blade is accurately adjusted through a motor-driven lead screw nut mechanism or a hydraulically driven piston mechanism, etc., to change the actual side clearance data. For example, for an initial alloy cold-rolled sheet with a higher hardness, appropriately reducing the side clearance can improve the finish and precision of the trimming; for an initial alloy cold-rolled sheet with a lower hardness, the side clearance can be appropriately increased to prevent the aluminum sheet from being over-extruded and deformed during the shearing process.

[0065] Optionally, at least one speed sensor is provided on the conveyor belt, and the speed sensor is connected to the automatic control module;

[0066] The speed sensor is used to monitor the traveling speed of the aluminum alloy material, the initial alloy cold-rolled plate, and the final alloy cold-rolled plate;

[0067] The automatic control module is also used to control the rotation speed of the driving motor of the disc shear 4 according to the travel speed.

[0068] Specifically, the speed sensor can be a laser speed meter or an encoder to monitor the travel speed in real time. When the thickness of the plate increases or the hardness of the material increases, in order to ensure the quality of the cutting edge, the automatic control module will automatically reduce the shearing speed of the disc shear 4 to prevent problems such as cutting edge burrs and tearing due to insufficient shearing force caused by too fast speed; for thinner or softer plates, the shearing speed can be appropriately increased to improve production efficiency. The drive motor of the disc shear 4 usually adopts a variable frequency motor. The automatic control module accurately adjusts the speed of the motor by changing the power supply frequency or control signal of the drive motor, thereby realizing real-time adjustment of the shearing speed of the disc shear 4.

[0069] Optionally, the automatic control module includes a multimodal physical enhancement hybrid unit, which is used to generate an operating data adjustment strategy for the circular shear 4 based on the current operating data of the uncoiler 1, the six-roll irreversible rolling mill 3 and the circular shear 4 and the material parameters.

[0070] Specifically, the automatic control module includes a multimodal physical enhancement hybrid unit for generating an operation data adjustment strategy for the circular shear 4 according to the current operation data of the uncoiler 1, the six-roll irreversible rolling mill 3 and the circular shear 4 and the material parameters, the current operation data including the current overlap, shear force data, tension data, uncoil tension, side gap data, travel speed and motor speed. The operation data adjustment strategy refers to adjusting the various operation data of the equipment, that is, adjusting one or more of the overlap, shear force data, tension data, uncoil tension, side gap data, travel speed and motor speed to achieve better production results.

[0071] Optionally, the multimodal physical enhancement hybrid unit includes a multimodal embedding layer, a spatiotemporal interaction layer, a physical constraint layer, an enhanced decision layer and an output layer connected in sequence;

[0072] The multimodal embedding layer is used to fuse the encoding and align the current operating data and the material parameters to generate a unified feature vector;

[0073] The spatiotemporal interaction layer is used to perform spatiotemporal association learning and dynamic weighting according to the unified feature vector to generate a spatiotemporal fusion feature vector;

[0074] The physical constraint layer is used to perform physical constraint verification on the spatiotemporal fusion feature vector to generate a verification feature vector;

[0075] The enhanced decision layer is used to convert the verification feature vector into an operation data adjustment strategy using a proximal strategy optimization algorithm;

[0076] The output layer is used to output the operation data adjustment strategy.

[0077] Specifically, the multimodal embedding layer is used to fuse the encoding and align the current operating data and material parameters to generate a unified feature vector, that is, to uniformly encode multiple current operating data and material parameters into machine-understandable joint features, and extract key information through branch networks, such as 1D-CNN, ViT, GAT, to eliminate redundant noise, achieve feature denoising and enhancement, and then ensure that the features of different data sources are aligned in the semantic space to generate a unified feature vector for subsequent spatiotemporal modeling. The spatiotemporal interaction layer first captures the parameter evolution trend through a multi-scale time window, performs time-dependent modeling, and performs spatial association learning to identify the interaction between local data and global data, or between devices, and dynamically weights each operating data according to the actual working conditions of the equipment to clarify the impact of a single data on the overall production efficiency, and obtain a spatiotemporal fusion feature vector. The physical constraint layer is used to embed the physical laws of the shearing process, improve the generalization of the model, and prevent anti-physical output, for example, the overlap is negative. The physical constraint layer predicts the model by embedding the differentiable shear force equation derived from the Hertz contact theory. The differentiable shear force equation includes:

[0078]

[0079] Among them, F shear is the shear force, k is the material coefficient, μ is the friction coefficient, S is the contact area, δ is the overlap, and h is the thickness of the aluminum plate.

[0080] The enhanced decision layer models the adjustment of the verification feature vector as a Markov decision process (MDP), and implements dynamic policy optimization through the proximal policy optimization (PPO) algorithm to obtain the operation data adjustment strategy, where the operation data adjustment strategy includes multiple different policy data of the same type, and the confidence levels of different policy data of the same type are different. Finally, the output layer outputs the policy data with the highest confidence level based on the confidence levels of each policy data.

[0081] Exemplarily, the present invention gives a specific embodiment to illustrate the implementation steps of the multimodal physical enhanced hybrid unit. The current operating data and material parameters of the uncoiler 1, the six-roll irreversible rolling mill 3, and the disc shear 4 include: the current overlap 0.3mm, shear force 320kN, tension 15MPa, uncoil tension 18MPa, side gap 0.12mm, travel speed 250m / min, motor speed 1450rpm, material 6XXX series aluminum alloy (coded as 2), hardness 120HB, thickness 2.5mm, first normalize each data and map it to the [0,1] interval, and obtain overlap 0.5, shear force 0.64, tension 0.4, uncoil tension 0.8, side gap 0.47, travel speed The normalized data are 0.83, the motor speed is 0.725, the material is 0.5, the hardness is 0.47, and the thickness is 0.44. The normalized data is input into the multimodal embedding layer. The multimodal embedding layer fuses and encodes the above data and aligns them. The multimodal embedding layer fuses and encodes the normalized data of the current running data through the numerical data branch (1D-CNN+gated attention) to obtain the weighted feature vector. The multimodal embedding layer then fuses and encodes the normalized data of the material parameters through the material attribute branch to obtain a multidimensional material vector. The weighted feature vector and the multidimensional material vector are then concatenated to obtain a unified feature vector. The unified feature vector is then input into the space-time interaction layer, which performs multi-scale time window processing to obtain time series features: 1min window: the tension is detected to drop from 18MPa to 15MPa (trend weight = 0.6); 5min window: shear force fluctuates periodically (increases by 10% every 5 minutes, weight = 0.3), and spatial association learning is performed at the same time: the equipment layout is mapped into a 2D grid, and the synergistic effect of equipment such as the six-roll irreversible rolling mill 3 and the disc shear 4 is identified (weight = 0.7) to obtain spatial features, and then the time series features and spatial features are spliced ​​to obtain the space-time fusion feature vector. The physical constraint layer introduces the overlap of 0.3mm and the thickness of 2.5mm into the differentiable shear force equation, and sets the material coefficient to 0.8, the friction coefficient to 0.2, and the contact area to 50, obtaining a shear force of 2.76kN. The residual calculation and physical constraint loss are calculated based on the shear force, and the residual is 317.24kN and the physical constraint loss is 10,065.4. The model parameters are adjusted through the back propagation of the physical constraint loss to make the predicted shear force approach the physical equation value. At the same time, the correctness of the parameters is clarified based on the differentiable shear force equation. That is, if the differentiable shear force equation can be operated normally, it means that the parameters are correct, and the time-space fusion feature vector is input into the enhanced decision layer as the verification feature vector; if the differentiable shear force equation cannot be operated normally, an error is directly reported.The enhanced decision layer inputs each feature data in the verification feature vector into the Actor network to obtain the corresponding strategy, and evaluates it through the Critic network to obtain the advantage function corresponding to the strategy, that is, the Actor generates an action based on the current state, the environment executes the action and feedbacks the reward and the new state, the Critic evaluates the state value and calculates the advantage value. If the Critic advantage value is 0.75, it means that the current strategy has a higher long-term benefit. The Actor uses the advantage value to adjust the strategy gradient and optimize the action selection, thereby obtaining the operation data adjustment strategy, among which PPO is a strategy optimization algorithm based on Actor-Critic. Finally, the output layer adjusts the priority from large to small according to the confidence level: overlap, side clearance, and shear speed. The final operation data adjustment strategy is: the overlap increases by 0.018mm, that is, the new overlap is 0.318mm, the side clearance decreases by 0.008mm, that is, the new side clearance is 0.112mm, and the shear speed increases by 3m / min, that is, the new shear speed is 253m / min.
