[0049] In order to improve efficiency and accuracy, the present application provides a method for analyzing the risk of thinning and stamping of steel plates. The method for analyzing the risk of thinning and stamping of steel plates provided in the present application is further described in detail below in combination with the accompanying drawings and specific implementation methods.

[0050] Please see attached Figure 1 , Figure 1 A schematic flow chart of a method for analyzing the risk of thinning and stamping of a steel plate provided in an embodiment of the present application. The method may include the following steps:

[0051] Step S101: receiving a thinning stamping request sent by a client device, wherein the thinning stamping request includes a unique identifier of a steel plate and thinning thickness parameters.

[0052] It should be noted that thinning stamping is usually to meet the design requirements of the product, such as reducing weight, improving performance or adapting to specific assembly requirements. The unique identification of the steel plate is used to uniquely identify the information of the steel plate to be processed. A serial number, batch number, barcode or any other form of unique code can include serial number, batch number, size specifications, etc. This identification can ensure accurate tracking and management during the production process to avoid confusion or mishandling. The thinning thickness parameter specifies the thickness that needs to be achieved by thinning, usually in millimeters or inches.

[0053] Step S102: Based on the unique identification of the steel plate, the material card and the mold geometry model of the steel plate are obtained from a preset database.

[0054] It should be noted that the preset database is a system that stores various information related to steel plate production. This information may include the unique identification of the steel plate, material card, die geometry model, production process parameters, historical processing records, etc. The database is designed to support fast and accurate retrieval of required information to support decision-making and operations in the production process. The material card is a detailed record of the material properties of the steel plate, and the material card of the steel plate includes the initial thickness parameters of the steel plate. The die geometry model is a three-dimensional model that describes the shape and size of the die during the stamping process. In the thinning stamping process, the geometry of the die directly determines the final shape and size of the stamped part.

[0055] In this application, the material card of the steel plate and the mold geometry model matching the current thinning and stamping task can be searched and obtained in the preset database according to the unique identification of the steel plate and the relevant production requirements.

[0056] Step S103: Based on the material card and the mold geometry model, simulate the initial stamping condition of the steel plate.

[0057] It should be noted that the stamping simulation software may be AUTOFORM, ANSYS, MATLAB / Simulink, etc.

[0058] In this application, the material card and the mold geometry model are imported into AUTOFORM to simulate the initial stamping condition of the steel plate, and the initial stamping conditions of the steel plate are set in AUTOFORM.

[0059] Specifically, the AUTOFORM software allows users to set various conditions in the stamping process according to actual needs, such as stamping speed, blank holder force, lubrication conditions, etc. These conditions have an important impact on the accuracy of the simulation results. In this step, it is necessary to ensure that the initial stamping conditions set in AUTOFORM are consistent with the actual situation so that the initial stamping conditions of the steel plate can be accurately simulated.

[0060] Once the material card, die geometry model and initial stamping conditions are set, AUTOFORM will start calculations. It uses advanced finite element analysis technology to simulate the deformation, stress and strain distribution of steel plates during the stamping process. Through calculations, AUTOFORM can predict the behavior of steel plates under initial stamping conditions, including which areas may wrinkle, crack or not fully deform.

[0061] After the calculation is completed, AUTOFORM can also generate a series of result data, including stress cloud map, strain cloud map, thickness distribution map, etc. These data help to intuitively understand the state of the steel plate under the initial stamping condition. By carefully analyzing these data, key areas such as the worst initial wrinkling point, the worst initial cracking point, and the worst initial undeformed point of the steel plate can be identified. These areas are the focus of subsequent optimization of the stamping process, improvement of mold design, or adjustment of material parameters.

[0062] Step S104: introducing a thinning thickness parameter based on the stamping condition of the steel plate to simulate the thinning stamping condition of the steel plate.

[0063] In this application, based on the stamping condition of the steel plate, the initial thickness parameter in Material-Thickness is modified to a thinning thickness parameter to simulate the thinning stamping condition of the steel plate.

[0064] Specifically, in AUTOFORM or other similar stamping simulation software, there is usually a Material-Thickness setting item for specifying the initial thickness of the material. In order to simulate the thinning stamping condition of the steel plate, it is necessary to modify the initial thickness parameter in this setting item to the target thickness after thinning.

[0065] In stamping simulation, ToolOffset is usually used to adjust the relative position between the die and the material. However, when simulating thinning stamping conditions, the focus is on the change in material thickness rather than the adjustment of the die position. Therefore, it is necessary to unlink Thickness from ToolOffset. In this way, during the simulation, the change in material thickness will not be affected by the change in die position.

[0066] Binder plays a role in fixing the edge of the material and preventing the material from wrinkling during the stamping process. When simulating the thinning stamping working condition, it is necessary to select the appropriate Binder support type. Gap controlled is a commonly used support type, which allows the user to control the effect of the Binder by setting the gap between the Binder and the material. After selecting Gap controlled, it can ensure that the Binder acts on the edge of the material in an appropriate manner during the thinning stamping process, thereby avoiding problems such as wrinkling.

[0067] After completing the above settings, you can start the simulation calculation. During the calculation process, except for the modified settings such as Material-Thickness and Tools-Binder-support type, the other settings related to the gap (such as gap size, mold gap, etc.) should remain unchanged. This can ensure the accuracy and comparability of the simulation results.

[0068] After the simulation calculation is completed, various state information of the steel plate under the thinning stamping condition can be obtained, including stress distribution, strain distribution, thickness change, etc. By carefully analyzing this information, key areas such as the worst point of thinning wrinkling, the worst point of thinning cracking, and the worst point of thinning without deformation can be identified. This information is of great significance for evaluating the feasibility of the thinning stamping process, optimizing the die design, and adjusting the process parameters.

[0069] Step S105: Analyze the initial stamping condition of the steel plate and the thinning stamping condition of the steel plate to obtain the thinning stamping risk of the steel plate.

[0070] In this application, the initial stamping condition of the steel plate and the thinning stamping condition of the steel plate are first associated in synchronization. Then, advanced Formability is used to analyze the worst initial wrinkling point and the worst thinning wrinkling point, the worst initial cracking point and the thinning cracking point, and the worst initial undeformed point and the worst undeformed point, respectively, to obtain the worst wrinkling point deviation, the worst cracking point deviation, and the worst undeformed point deviation. Finally, based on the worst wrinkling point deviation, the worst cracking point deviation, and the worst undeformed point deviation, the thinning stamping risk of the steel plate is determined.

[0071] Specifically, in the synchronization function of the simulation software, the calculation results of the initial stamping condition and the thinning stamping condition are linked. This ensures that when conducting comparative analysis, they can accurately correspond to the same material area and process conditions.

[0072] Next, the software’s “advanced Formability” function is used to conduct an in-depth comparison of the forming performance under the two conditions. This function usually provides rich visualization tools and quantitative indicators to help comprehensively evaluate the forming quality.

[0073] During the comparison process, the worst points of wrinkling (z), cracking (l) and no deformation (w) are selected. These points represent the limit of forming quality under the two working conditions. Through the synchronization function, it is ensured that the characteristic points selected in the initial working condition and the thinning working condition can correspond one to one, thus ensuring the accuracy and consistency of the comparative analysis.

[0074] At the wrinkle risk point, the wrinkles index is used for data comparison and evaluation. The wrinkless index can quantify the possibility of wrinkling of the material during the stamping process. By comparing the wrinkles values ​​under the initial working condition and the thinning working condition, the impact of the thinning operation on the wrinkle risk can be evaluated.

[0075] At the cracking risk, the max failure (advanced) index is used for evaluation. This index reflects the maximum degree of damage of the material under a specific stress state. By comparing the max failure values ​​under two working conditions, the impact of the thinning operation on the cracking risk can be evaluated.

[0076] The risk point deviation rating is performed based on the degree of deviation between the initial calculation and the thinning calculation at the worst points of wrinkling, cracking and non-deformation. The rating standards can be formulated according to actual needs and process requirements, and usually include levels such as no deviation, slight deviation, medium deviation and severe deviation. The deviation rating results directly reflect the risk level that may exist in the thinning stamping process, and can provide an important basis for subsequent optimization design.

[0077] If the deviation of the worst point for wrinkling, the deviation of the worst point for cracking, and the deviation of the worst point for non-deformation are all positive values, or if there is a negative value but its rate of change is less than all positive values ​​and is very small (such as less than 10%), it means that the thinning operation may have improved the situation of these risk points or the negative change is small, and the overall trend is positive, that is, a single thinning sheet thickness plan is feasible, and there is no need to further adjust the stamping process or steel plate properties.

[0078] If there is at least one positive value among the worst point deviation of wrinkling, the worst point deviation of cracking, and the worst point deviation of non-deformation, and the negative value change rate is relatively small (such as less than 20%), it means that the negative change is small, and the thinning operation is beneficial in some aspects. However, the negative value change still needs special attention because it may indicate potential problems. That is, a single thinning plan is basically feasible, and the impact of negative values ​​needs to be evaluated separately to determine whether it will have an unacceptable impact on the quality of the final product. If the risk pointed to by the negative value change (such as an increased risk of cracking) is within an acceptable range, the plan can continue to be implemented; otherwise, it may be necessary to consider adjusting the stamping process or steel plate properties to mitigate this impact.

[0079] If it is not one of the above two situations, it means that the risk of a single thinning solution is relatively high and additional measures need to be taken to reduce the risk. That is, the risk of a single thinning solution is relatively high and the stamping process or steel plate performance needs to be adjusted and compensated. The stamping process parameters (such as stamping speed, pressure distribution, etc.) can be adjusted, the mold design can be optimized, the steel plate material with better forming performance can be selected, or a composite thinning strategy can be adopted.

[0080] In summary, the present application provides a method for analyzing the thinning and stamping risk of a steel plate, which receives a thinning and stamping request sent by a client device, wherein the thinning and stamping request includes a unique identifier and a thinning thickness parameter of the steel plate. Based on the unique identifier of the steel plate, the material card and the mold geometry model of the steel plate are obtained from a preset database. Based on the material card and the mold geometry model, the initial stamping condition of the steel plate is simulated. Based on the stamping condition of the steel plate, the thinning thickness parameter is introduced to simulate the thinning and stamping condition of the steel plate. The initial stamping condition of the steel plate and the thinning and stamping condition of the steel plate are analyzed to obtain the thinning and stamping risk of the steel plate. The present application greatly improves the efficiency and accuracy of the analysis by automatically receiving thinning and stamping requests, retrieving material cards and mold models from a database, and performing simulation analysis based on these data.
