Description

Technical Field

[0001] This application belongs to the field of metal processing technology, and in particular relates to a method, apparatus, terminal equipment and storage medium for processing metal sheets. Background Technology

[0002] In the processing of sheet metal, heat treatment is often required to improve its performance. However, during heat treatment, uneven cooling rates, phase transformations in the metal, and structural deformation can lead to residual uneven stress within the sheet metal, resulting in an uneven surface that does not meet the shape requirements of subsequent processing.

[0003] To address these issues, a straightening process is often added after heat treatment when processing sheet metal to eliminate stress through repeated plastic deformation. However, excessive straightening can easily lead to metal fatigue, causing cracks in the sheet metal. Alternatively, straightening can be performed during heat treatment, taking advantage of the sheet metal's still relatively good plasticity during cooling to reduce the difficulty and number of straightening operations. However, uneven cooling after straightening can still cause warping, resulting in a final sheet metal that does not meet requirements.

[0004] Therefore, how to control the processing of metal sheets to reduce the number of straightening operations while ensuring that the shape of the finished metal sheet meets the requirements of subsequent processing is an urgent problem to be solved in the current metal processing process. Summary of the Invention

[0005] This application provides a method and apparatus for processing metal sheets, which can solve the problems of difficulty in straightening metal sheets after heat treatment and excessive straightening times.

[0006] In a first aspect, embodiments of this application provide a method for processing metal sheets, comprising:

[0007] Under the constraint of the number of straightening cycles, the heat treatment control parameters are obtained based on the parameter information of the first metal sheet and the processing target information;

[0008] The parameter information of the first metal sheet includes the shape information and the identity information of the first metal sheet. The first metal sheet is used to heat-treat the second metal sheet under the control of the heat treatment control parameters. The straightening number constraint is a constraint condition that the expected straightening number is not greater than a preset threshold. The expected straightening number is determined based on the expected stress information of the second metal sheet.

[0009] The above method obtains heat treatment control parameters based on the parameter information of the first metal sheet and the processing target information under the constraint of the number of straightening cycles. This ensures that the obtained heat treatment control parameters meet both the target processing information and the straightening cycle requirement. Specifically, the expected number of straightening cycles for the second metal sheet is determined using the expected stress information. The heat treatment control parameters are then correlated with the number of straightening cycles after heat treatment through stress information. This allows the determination of whether the obtained heat treatment control parameters meet the straightening cycle requirement simply by determining the expected stress information of the second metal material.

[0010] Meanwhile, the metal sheet is processed according to the above-mentioned heat treatment control parameters. During the processing, the stress information inside the metal sheet can be adjusted through the heat treatment process, and corresponding adjustments can be made according to the parameter information of the first metal sheet. This ensures that the stress of the processed second metal sheet meets the straightening number constraint, reducing the subsequent straightening number and processing difficulty of the metal sheet.

[0011] In one possible implementation of the first aspect, the expected stress information of the second metal plate is determined based on the expected shape information of the second metal plate; the expected shape information of the second metal plate is determined based on the parameter information of the first metal plate and preset heat treatment parameters.

[0012] The above method determines the corresponding expected stress information based on the expected shape information of the metal sheet. This allows the determination of the expected stress information of the second metal sheet only by knowing its expected shape information when acquiring the heat treatment control parameters. This transforms the difficult-to-predict quantity of expected stress information into the more easily obtainable quantity of expected shape information. Consequently, during the processing of the metal sheet, only the shape of the metal sheet needs to be considered, reducing the difficulty of process inspection.

[0013] In one possible implementation, the step of obtaining the heat treatment control parameters based on the parameter information of the first metal sheet and the processing target information under the constraint of the number of straightening cycles includes:

[0014] Preliminary heat treatment parameters are obtained based on the parameter information of the first metal plate and the processing target information;

[0015] The expected stress information of the second metal plate is obtained based on the parameter information of the first metal plate and the pre-heating parameters.

[0016] The expected number of straightening cycles is obtained based on the expected stress information of the second metal plate;

[0017] If it is determined that the expected number of straightening cycles is not greater than a preset threshold, then the pre-conditioning parameters are determined as the conditioning control parameters;

[0018] If the expected number of straightening cycles is determined to be greater than the preset threshold, the pre-heating parameters are adjusted, and the process returns to the step of obtaining the expected stress information of the second metal plate based on the parameter information of the first metal plate and the pre-heating parameters, until the preset stopping condition is met.

[0019] The above method, by judging and adjusting the pre-conditioning parameters, and based on meeting the processing target information, filters and adjusts the pre-conditioning parameters to obtain conditioning control parameters that meet the straightening cycle constraints. By stopping the adjustment of the pre-conditioning parameters when a preset stopping condition is met, the system avoids crashing when conditioning control parameters cannot be obtained for an extended period.

[0020] In one possible implementation of the first aspect, the first metal sheet is quenched to obtain a third metal sheet, and the third metal sheet is tempered to obtain a second metal sheet; the tempering control parameters include quenching control parameters and tempering control parameters.

[0021] The processing method of the metal sheet further includes:

[0022] The first metal plate is quenched based on the quenching control parameters to obtain the third metal plate.

[0023] Obtain the shape information of the third metal plate, and obtain the stress information of the third metal plate based on the shape information of the third metal plate;

[0024] Under the constraint of the number of straightening cycles, the tempering control parameters are adjusted according to the stress information of the third metal plate;

[0025] The third metal sheet is tempered based on the adjusted tempering control parameters to obtain the second metal sheet.

[0026] The above method obtains the shape information of the third metal material after quenching, tracks the changes in the steel plate shape, and then obtains the stress information of the third metal plate. The tempering control parameters are adjusted based on this stress information, and the tempering process is controlled according to the actual condition of the metal plate. By utilizing the characteristic that the metal material deforms during tempering, the stress generated during quenching is adjusted, and the plate shape and stress during steel plate processing are adjusted in a timely manner. This avoids the problem of excessive difficulty in straightening the steel plate due to severe deformation during subsequent straightening.

[0027] In one possible implementation of the first aspect, the step of adjusting the tempering control parameters based on the stress information of the third metal sheet under the constraint of the number of straightening cycles includes:

[0028] Based on the composition information, shape information, stress information of the first metal plate, shape information and stress information of the third metal plate, a three-dimensional mechanical model is constructed by calling the historical database.

[0029] The mechanical three-dimensional model is used to simulate the stress changes from the first metal sheet to the second metal sheet during the processing;

[0030] Using the tempering control parameters as input, the mechanical three-dimensional model is run to obtain the expected stress information of the second metal plate, and the expected number of straightening cycles is obtained based on the expected stress information of the second metal plate.

[0031] If it is determined that the expected number of straightening cycles is not greater than a preset threshold, then the tempering control parameter is determined to be the adjusted tempering control parameter;

[0032] If the expected number of straightening cycles is determined to be greater than the preset threshold, the tempering control parameters are adjusted, and the process returns to the step of obtaining the expected stress information of the second metal plate based on the parameter information of the first metal plate and the pre-tempering parameters, until the preset first stop condition is met.

[0033] The aforementioned method establishes a corresponding mechanical model based on the composition, shape, stress information, and historical database of the metal sheet. This makes the established three-dimensional mechanical model more accurate and enables more precise simulation of stress changes in the second metal sheet during processing. By constructing a three-dimensional mechanical model to simulate the stress of the metal material during processing, the expected stress information corresponding to different parameter information and different spark control parameters can be obtained, and the obtained expected stress information is more accurate. Furthermore, the construction of the three-dimensional mechanical model provides data support for the subsequent straightening process.

[0034] In one possible implementation of the first aspect, the second metal sheet is straightened to obtain the fourth metal sheet;

[0035] The step of obtaining the expected number of straightening cycles based on the expected stress information of the second metal plate includes:

[0036] Based on the expected stress information of the second metal plate, a straightening model is constructed by calling the historical database; the straightening model is used to simulate the stress changes of the second to the fourth metal plates during the straightening process;

[0037] Using preset straightening parameters as input, the straightening model is run to obtain the expected number of straightening cycles.

[0038] The above method constructs a straightening model to simulate stress changes during the metal straightening process, enabling the determination of the number of straightening operations based on expected stress information. By simulating the straightening model based on a historical database, the expected number of straightening operations obtained from the straightening model becomes more accurate and can be used as a condition for whether the preset modulation parameters meet the straightening operation constraint.

[0039] In one possible implementation of the first aspect, the processing target information includes target flatness and / or target stress information;

[0040] Also includes:

[0041] Once the processing of the second metal sheet is completed, obtain the shape information and / or stress information of the second metal sheet;

[0042] Using the shape information and / or stress information of the second metal plate as input, the straightening model is run to obtain the stress information of the fourth metal plate under the preset pre-straightening parameters;

[0043] If the stress information of the fourth metal plate is determined to meet the target stress information, then the pre-straightening parameter is determined as the straightening control parameter; otherwise, the pre-straightening parameter is adjusted and the process returns to the step of running the straightening model with the shape information and / or stress information of the second metal plate as input to obtain the stress information of the fourth metal plate under the preset pre-straightening parameters, until the preset second stop condition is met.

[0044] The above method inputs the shape information and / or stress information of the second metal plate and the pre-straightening parameters into the straightening model to obtain the stress information of the fourth metal plate under the preset pre-straightening parameters, and adjusts the pre-straightening parameters in a targeted manner according to the shape information and / or stress information of the second metal plate.

[0045] Secondly, embodiments of this application provide a metal sheet processing apparatus, comprising:

[0046] The heat treatment control module is used to obtain heat treatment control parameters based on the parameter information of the first metal sheet and the processing target information under the constraint of the number of straightening cycles;

[0047] The parameter information of the first metal sheet includes the shape information and the identity information of the first metal sheet. The first metal sheet is used to heat-treat the second metal sheet under the control of the heat treatment control parameters. The straightening number constraint is a constraint condition that the expected straightening number is not greater than a preset threshold. The expected straightening number is determined based on the expected stress information of the second metal sheet.

[0064] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details.

[0070] In the processing of sheet metal, heat treatment is often required to improve its performance. However, during heat treatment, uneven cooling rates, phase transformations, and structural deformation can lead to residual uneven stress within the metal, causing the sheet metal to become uneven and fail to meet the shape requirements of subsequent processing. Therefore, it is necessary to straighten the sheet metal after heat treatment, using repeated deformation and shaping to eliminate stress and improve its shape to meet the requirements of subsequent processing.

[0071] However, due to the severe deformation of metals during heat treatment, especially for thinner metal sheets, which are highly sensitive to temperature and deform particularly severely, the internal stress release process leads to even greater deformation than that of steel plates. Therefore, thin steel plates require multiple straightening processes in the later stages. However, excessive straightening can lead to metal fatigue and cracking.

[0072] To address the aforementioned technical problems, a feasible solution is to determine the straightening strategy based on the sheet shape of the metal material after heat treatment, and to precisely control the straightening parameters during the straightening process to reduce the number of straightening operations. Alternatively, the metal sheet can be straightened directly during the heat treatment process, thus reducing the difficulty of straightening.

[0073] However, with current technology, whether changing the straightening steps and methods or refining the straightening parameters, the improvement lies in the straightening process itself, eliminating internal stress in the metal through repeated plasticity. It fails to consider that the heat treatment process of the metal material itself affects the plate shape and internal stress. Adjusting the heat treatment process can adjust internal stress and improve the plate shape.

[0074] See the instruction manual appendix Figure 1 Based on the above technical concept, this application proposes a method for processing metal sheets, including:

[0075] Step S102: Under the constraint of the number of straightening cycles, obtain the heat treatment control parameters based on the parameter information of the first metal plate and the processing target information;

[0076] The parameter information of the first metal sheet includes the shape information and the identity information of the first metal sheet. The first metal sheet is used to heat-treat the second metal sheet under the control of the heat treatment control parameters. The straightening number constraint is a constraint condition that the expected straightening number is not greater than a preset threshold. The expected straightening number is determined based on the expected stress information of the second metal sheet.

[0077] The tempering process refers to the heat treatment process of metal plates, including quenching, tempering, and normalizing of steel, as well as solution quenching, aging heat treatment, high-temperature homogenization annealing of copper, and heat treatment processes for other metals. The tempering control parameters are parameters used when heat treating metals, including furnace loading temperature, heating temperature, cooling time, cooling rate, heating and cooling rates, holding time, and cooling method.

[0078] The parameter information of the first metal sheet includes its shape information and identity information. The identity information of the metal sheet includes its composition, type, and specifications. In this embodiment, the shape information of the metal sheet can be obtained by scanning the metal sheet and sensing its thickness to obtain its shape data. Optionally, the shape information of the metal sheet can be obtained by scanning it after each step of the metal processing process.

[0079] The shape information of the metal material can be used to determine its stress information. The processing target information can be determined based on the manufacturer's processing requirements or on the processing requirements of subsequent processing steps. Optionally, the processing target information includes the target shape of the metal material, as well as target strength and target toughness requirements, etc.

[0080] The preset threshold for the metal sheet is set based on experience in processing different metal sheets. For example, in steel processing, if experience shows that cracks begin to appear in the steel sheet after five straightening operations, then the preset threshold can be set to 5. Generally, the preset threshold differs for metal sheets of different shapes. For instance, thin steel sheets are more prone to metal fatigue than thick steel sheets, and their preset threshold should be lower than that of thick steel sheets.

[0081] The expected stress information of the second metallic material is obtained by processing it according to a preset heat treatment control parameter. This expected stress information is a predicted value, while the actual stress information is different. The heat treatment control parameter to be determined can be compared with the heat treatment control parameters used in previous production processes to predict the corresponding stress information of the second metallic material. Alternatively, the parameter information of the first metallic material and the heat treatment control parameter to be determined can be input into the corresponding model to obtain the expected stress information of the second metallic material.

[0082] In one optional implementation, after determining the expected stress information of the second metal sheet, it is possible to predict whether the second metal material can be processed to obtain a metal sheet that meets the processing target based on historical data of previous straightening processes and preset straightening parameters; or the expected stress information of the second metal material, the processing target information, and the preset straightening parameters are input into the relevant straightening model to obtain the relevant straightening parameters and determine the expected number of straightening operations.

[0083] After determining the expected number of straightening operations, the obtained expected number of straightening operations is compared with the preset threshold to determine whether the number of straightening operations of the second metal material obtained by processing according to the preset heat treatment parameters meets the constraint conditions. If the constraint conditions are met, the preset heat treatment parameters can be used as heat treatment control parameters, and the second metal material can be obtained by processing according to the heat treatment control parameters.

[0084] The beneficial effects of this embodiment are as follows:

[0085] This embodiment obtains heat treatment control parameters based on the parameter information of the first metal sheet and the processing target information under the constraint of the number of straightening cycles. The obtained heat treatment control parameters satisfy both the target processing information and the requirement for the number of straightening cycles. Specifically, the expected number of straightening cycles for the second metal sheet is determined by the expected stress information of the second metal sheet. The heat treatment control parameters are correlated with the number of straightening cycles after heat treatment through stress information. Therefore, when determining the heat treatment control parameters, only the expected stress information of the second metal material needs to be determined to determine whether the obtained heat treatment control parameters meet the straightening cycle requirement.

[0086] Meanwhile, the metal sheet is processed according to the above-mentioned heat treatment control parameters. During the processing, the stress information inside the metal sheet can be adjusted through the heat treatment process. By making corresponding adjustments according to the parameter information of the first metal sheet, the stress of the processed second metal sheet can meet the straightening number constraint as much as possible, thereby reducing the subsequent straightening number and processing difficulty of the metal sheet.

[0087] According to the above embodiments, in yet another embodiment:

[0088] The expected stress information of the second metal plate is determined based on the expected shape information of the second metal plate; the expected shape information of the second metal plate is determined based on the parameter information of the first metal plate and the preset heat treatment parameters.

[0089] The expected stress information of the second metal sheet refers to the expected stress information of the second metal material obtained by processing the first metal material according to the preset heat treatment parameters, for any preset heat treatment parameters. This includes, for example, the expected distribution and magnitude of stress within the second metal sheet. Correspondingly, the expected shape information of the second metal material is the expected shape information of the second metal sheet obtained according to the preset heat treatment parameters, including the thickness of the metal sheet at different locations. The preset heat treatment parameters refer to any preset heat treatment parameters, which can be heat treatment control parameters or pre-set heat treatment parameters.

[0090] The expected stress information of the metal sheet can be obtained by comparing the expected shape information of the second metal sheet with the shape information of the first metal sheet. The expected shape information of the second metal sheet can be obtained from the process effect of the quenching and tempering process based on the previous production information. The expected shape information of the second metal material can be predicted based on the process effect of the quenching and tempering process.

[0091] Optionally, the expected stress information and expected shape information of the second metal sheet can be obtained based on the heat treatment model. By establishing a model of the heat treatment process and taking the parameter information of the first metal material and the preset expected shape information as input, the corresponding expected stress information and expected shape information can be obtained.

[0092] The beneficial effects of this embodiment are as follows:

[0093] Based on the expected shape information of the metal sheet, the corresponding expected stress information is determined. This allows for the determination of the expected stress information of the second metal sheet simply by knowing its expected shape information when acquiring the heat treatment control parameters. This transforms the difficult-to-predict quantity of expected stress information into the more easily obtainable quantity of expected shape information. Consequently, during the processing of the metal sheet, only the shape of the metal sheet needs to be considered, reducing the difficulty of process inspection.

[0094] Based on the above embodiments, see the appendix to the specification. Figure 2 In yet another embodiment:

[0095] The step of obtaining the heat treatment control parameters based on the parameter information of the first metal sheet and the processing target information under the constraint of the number of straightening cycles includes:

[0096] Preliminary heat treatment parameters are obtained based on the parameter information of the first metal plate and the processing target information;

[0097] The expected stress information of the second metal plate is obtained based on the parameter information of the first metal plate and the pre-heating parameters.

[0098] The expected number of straightening cycles is obtained based on the expected stress information of the second metal plate;

[0099] Specifically, the expected stress information of the second metal plate can be input into the expected straightening model to obtain the expected number of straightening operations.

[0100] If it is determined that the expected number of straightening cycles is not greater than a preset threshold, then the pre-conditioning parameters are determined as the conditioning control parameters;

[0101] If the expected number of straightening cycles is determined to be greater than the preset threshold, the pre-heating parameters are adjusted, and the process returns to the step of obtaining the expected stress information of the second metal plate based on the parameter information of the first metal plate and the pre-heating parameters, until the preset stopping condition is met.

[0102] The step "obtaining preliminary quenching and tempering parameters based on the parameter information of the first metal plate and the processing target information" involves obtaining quenching and tempering parameters that enable the first metal material to undergo quenching and tempering processing to meet the processing target information, based on the main process effects of the quenching and tempering process. For example, in the quenching and tempering process of steel, the main process effects of quenching and tempering are to change the hardness, toughness, and ductility of the steel. In this case, the preliminary quenching and tempering parameters can be determined based on the hardness, toughness, and ductility requirements of the target steel plate in the processing target information, as well as the parameter information of the first metal material, without considering the shape requirements and stress requirements in the processing target.

[0103] Specifically, when obtaining the preliminary heat treatment parameters, the processing target information and parameter information of the first metal plate in the previous production and processing process can be compared with the current processing target information and parameter information of the first metal plate to obtain the preliminary heat treatment parameters; or the parameter information of the first metal plate and the processing target information can be input into the corresponding heat treatment model to obtain the preliminary heat treatment parameters.

[0104] Alternatively, the previous heat treatment control parameters that meet the processing target information obtained based on experience can be directly used as the preliminary heat treatment control parameters.

[0105] Optionally, if there are multiple heat treatment control parameters, the obtained heat treatment control parameters can be verified multiple times to verify whether the straightening number constraint is met.

[0106] The preset stopping conditions may include:

[0107] 1. When performing the above steps, if the number of iterations is too large, it is still impossible to obtain the heat treatment control parameters that meet the straightening number constraint.

[0108] 2. When performing the above steps, as the expected stress information of the second metallic material obtained based on the pre-heating parameters increases,

[0109] Optionally, after the quenching and tempering process is completed, the pre-quenching and tempering parameters can be adjusted according to the stress information of the second metal material, and the plate shape of the steel plate can be improved as much as possible while meeting the constraints of the expected quenching and tempering parameters.

[0110] In an optional implementation, if the expected number of straightening cycles is greater than the preset threshold, when adjusting the pre-heating parameters, past production experience can be referenced to adjust the pre-heating parameters. For example, based on past production experience, it is known that the heating temperature, heating rate, holding time, cooling time, and cooling rate during tempering are related to the stress release process. Therefore, when adjusting the pre-heating parameters, the above parameters can be adjusted to eliminate stress while meeting the target processing information.

[0111] If the adjustment direction of the pre-heating parameters cannot be determined, the parameters in the heat control parameters are adjusted sequentially, and the expected stress information of the corresponding second metal material is determined based on the adjusted expected heat-heating parameters. The expected stress information of multiple adjusted second metal materials is used as the basis for adjustment to determine the adjustment direction of the pre-heating parameters, and then it is confirmed whether the readjusted pre-heating parameters meet the constraint of the number of straightening cycles.

[0112] The beneficial effects of this embodiment are as follows:

[0113] In this embodiment, preliminary heat treatment parameters are obtained based on the parameter information of the first metal plate and the target processing information, so that the obtained preliminary heat treatment parameters can meet the processing target requirements. The expected stress information of the metal plate is determined based on the parameter information of the first metal plate and the preliminary heat treatment parameters, and the number of straightening times is determined based on the expected stress information. Then, it is confirmed whether the preliminary heat treatment parameters meet the straightening time constraint and whether the stress can be adjusted during the processing so that the heat-treated second metal material can meet the straightening time constraint.

[0114] Taking steel plates as an example, their heat treatment process often includes quenching and tempering. When processing steel plates, quenching is necessary to obtain some or all of the high-strength microstructures, such as martensite or bainite, and then tempering is used to ensure the uniformity of the steel plate's microstructure. During quenching, the steel needs to be processed above its cooling temperature and then rapidly cooled to increase its hardness. After quenching, the cooling stress of the steel changes significantly. Therefore, if the steel plate is then tempered based on previously obtained tempering control parameters, the tempering control may not be precise enough.

[0115] Therefore, to solve the above problems, please refer to the appendix to the instruction manual. Figure 1 In yet another embodiment:

[0116] The first metal sheet is quenched to obtain the third metal sheet, and the third metal sheet is tempered to obtain the second metal sheet; the tempering control parameters include quenching control parameters and tempering control parameters;

[0117] The processing method of the metal sheet further includes:

[0118] Step S104: Quench the first metal plate based on the quenching control parameters to obtain the third metal plate;

[0119] Step S106: Obtain the shape information of the third metal plate, and obtain the stress information of the third metal plate based on the shape information of the third metal plate;

[0120] Step S108: Under the constraint of the number of straightening cycles, adjust the tempering control parameters according to the stress information of the third metal plate;

[0121] Step S110: Temper the third metal plate based on the adjusted tempering control parameters to obtain the second metal plate.

[0122] Specifically, when obtaining the stress information of the third metal plate based on its shape information, the shape information of the third metal plate can be compared with that of the first metal plate to obtain the shape change information of the metal plate during the quenching process. For different steel grades with the same shape change, their stress information changes may not be the same. Therefore, it is necessary to determine the stress information of the metal plate based on its identity information, stress information, shape change information during the quenching process, and identity information.

[0123] Regarding the step "adjusting the tempering control parameters according to the stress information of the third metal plate under the constraint of the straightening number", after quenching, the stress information of the third metal plate changes compared to the stress information of the first metal plate. At this time, the tempering control parameters are adjusted according to the stress information of the third metal plate, so that the tempering process can adjust the parameters according to the stress information of the third metal plate, and adjust the stress and plate shape of the metal plate after quenching to obtain a better tempering effect.

[0124] The tempering parameters are adjusted based on the stress information of the third metal plate. The tempering control parameters can be adjusted according to the stress information of the third metal plate, the processing target, and the expected shape information of the second metal plate.

[0125] The beneficial effects of this embodiment are as follows:

[0126] This embodiment obtains the shape information of a third metal material after quenching, tracks changes in the steel plate's profile, and then acquires the stress information of the third metal plate. The tempering control parameters are adjusted based on this stress information, allowing for control of the tempering process according to the actual condition of the metal plate. By leveraging the characteristic that metal materials deform during tempering, the stress generated during quenching is adjusted, and the plate shape and stress during steel plate processing are adjusted promptly. This avoids the problem of excessive difficulty in straightening the steel plate due to severe deformation during subsequent straightening.

[0127] According to the above embodiments, in yet another embodiment:

[0128] The step of adjusting the tempering control parameters based on the stress information of the third metal plate under the constraint of the number of straightening cycles includes:

[0129] Based on the composition information, shape information, stress information of the first metal plate, shape information and stress information of the third metal plate, a three-dimensional mechanical model is constructed by calling the historical database.

[0130] The mechanical three-dimensional model is used to simulate the stress changes from the first metal sheet to the second metal sheet during the processing;

[0131] Using the tempering control parameters as input, the mechanical three-dimensional model is run to obtain the expected stress information of the second metal plate, and the expected number of straightening cycles is obtained based on the expected stress information of the second metal plate.

[0132] If it is determined that the expected number of straightening cycles is not greater than a preset threshold, then the tempering control parameter is determined to be the adjusted tempering control parameter;

[0133] If the expected number of straightening cycles is determined to be greater than the preset threshold, the tempering control parameters are adjusted, and the process returns to the step of obtaining the expected stress information of the second metal plate based on the parameter information of the first metal plate and the pre-tempering parameters, until the preset first stop condition is met.

[0134] The shape information of the metal material can be obtained by measuring the thickness of the metal sheet using sensors. Optionally, the thickness of the sheet can be measured using the sheet surface as a two-dimensional coordinate system to establish a corresponding three-dimensional model. The stress information of the metal sheet can be measured using electrical methods, fiber optic grating methods, or vibrating wire strain gauges. Alternatively, the stress information of the third metal sheet can be obtained based on the shape change information of the first and third metal sheets.

[0135] The beneficial effects of this embodiment are as follows:

[0136] This embodiment establishes a corresponding mechanical model based on the composition, shape, stress information, and historical database of the metal sheet. This makes the established three-dimensional mechanical model more accurate and allows for more precise simulation of stress changes in the second metal sheet during processing. By constructing a three-dimensional mechanical model to simulate the stress of the metal material during processing, the expected stress information corresponding to different parameter information and different spark control parameters can be obtained, making the obtained expected stress information more accurate. Simultaneously, the construction of the three-dimensional mechanical model provides data support for the subsequent straightening process.

[0137] According to the above embodiments, in yet another embodiment:

[0138] The second metal sheet is straightened to obtain the fourth metal sheet;

[0139] The step of obtaining the expected number of straightening cycles based on the expected stress information of the second metal plate includes:

[0140] Based on the expected stress information of the second metal plate, a straightening model is constructed by calling the historical database; the straightening model is used to simulate the stress changes of the second to the fourth metal plates during the straightening process;

[0141] Using preset straightening parameters as input, the straightening model is run to obtain the expected number of straightening cycles.

[0142] The historical database includes the types, compositions, and shape and stress information of different metal materials, as well as their processing history. When constructing the straightening model, the stress information of the second metal plate can be obtained from the historical database when the second metal plate is processed with different straightening parameters. The shape of the metal plate and the internal residual stress can be simulated to determine the expected number of straightening operations.

[0143] Optionally, the preset straightening parameters include the downward pressure, inlet roll gap, outlet roll gap, and straightening speed. Optionally, when the obtained preset number of straightening cycles does not meet the constraints, the preset straightening parameters can be adjusted within a preset range to verify whether the preset straightening conditions can be met.

[0144] In an optional implementation, the straightening model is further used to adjust straightening parameters. After the heat treatment is completed, the stress information of the second metal material and the preset straightening parameters can be input into the pre-straightening model based on the stress information of the second metal material. The straightening model is then used to simulate the stress changes of the second metal material during the straightening process. Based on this, the preset straightening parameters are adjusted to obtain the straightening control parameters.

[0145] Optionally, after the straightening process is completed, the historical database can be updated based on the stress information of the fourth metallic material, and the straightening model can be reconstructed based on the historical database. Alternatively, the constructed straightening model can be adjusted.

[0146] The beneficial effects of this embodiment are as follows:

[0147] This embodiment constructs a straightening model to simulate the stress changes during the metal straightening process, enabling the determination of the number of straightening operations based on expected stress information. The simulation of the straightening model based on a historical database is more accurate than that obtained from a model, and can be used as a condition for whether the preset modulation parameters meet the straightening operation constraint.

[0152] Using the shape information and / or stress information of the second metal plate as input, the straightening model is run to obtain the stress information of the fourth metal plate under the preset pre-straightening parameters;

[0153] If the stress information of the fourth metal plate is determined to meet the target stress information, then the pre-straightening parameter is determined as the straightening control parameter; otherwise, the pre-straightening parameter is adjusted and the process returns to the step of running the straightening model with the shape information and / or stress information of the second metal plate as input to obtain the stress information of the fourth metal plate under the preset pre-straightening parameters, until the preset second stop condition is met.

[0154] The pre-set straightening parameters can be straightening parameters preset based on experience. The number of straightening passes of the straightening parameters does not exceed a preset threshold. The preset second stopping condition can be that the number of iterations exceeds a preset number, or the number of straightening passes in the straightening control parameters exceeds a preset threshold, or the stress information of the fourth metal plate obtained when simulating in the straightening model according to the pre-set straightening parameters deviates from the target stress information by more than a preset range.

[0155] The adjustment steps for the pre-straightening parameters can begin by keeping the number of straightening passes constant and determining the straightening reduction. Based on the straightening reduction, the inlet roll gap, outlet roll gap, and straightening speed are then determined.

[0156] Optionally, after the second metal sheet is processed, the shape information and / or stress information of the second metal sheet are obtained. If the obtained straightening parameters are greater than a preset threshold, or if the preset stop condition is met when the straightening control parameters are adjusted, the system will classify and alarm according to different plate types and actual on-site conditions. In severe cases, the machine will be stopped first and then processed.

[0157] The beneficial effects of this embodiment are as follows:

[0158] In this embodiment, the shape information and / or stress information of the second metal plate and the pre-straightening parameters are input into the straightening model to obtain the stress information of the fourth metal plate under the preset pre-straightening parameters, and the pre-straightening parameters are adjusted in a targeted manner according to the shape information and / or stress information of the second metal plate.
