Detailed Description of the Embodiment

[0024] The following further describes the present application in detail with reference to the drawings.

[0025] In an embodiment, as Figure 1As shown in the figure, the present application discloses a simulation test method for a cutting and punching device, which specifically includes the following steps: S10: Obtain the structural data of the cutting and punching device, and based on the structural data, construct a preliminary virtual simulation model of the cutting and punching device.

[0026] Specifically, obtain the structural data of each mechanism by collecting equipment drawings, assembly records, and on-site measurement data, convert the connection methods, dimensions, and assembly relationships of each mechanism into a standard digital format, and then use NX_MCD to import this data to create a mechanical model. Mechanical modeling is the most fundamental function of NX software. Combine data conversion algorithms to establish a preliminary virtual simulation model of the cutting and punching device. This model can accurately reflect the actual layout and mutual connection of the conveying mechanism, punching mechanism, cutting mechanism, and material cutting mechanism in space.

[0027] S20: Define the component characteristics of each component in the preliminary virtual simulation model to obtain a virtual simulation model.

[0028] Specifically, perform equipment motion simulation in NX_MCD. The MCD component creates a physical field, defines the three-dimensional model and endows it with physical properties such as weight, force, and collision, and then makes it move in a specified manner. Define the component characteristics of each component in the preliminary virtual simulation model, including setting physical properties for each component, determining mass, inertia, and friction coefficients by referring to actual measurement values or standard material data, and at the same time establishing the motion relationships and constraint conditions between components, clarifying the motion trajectories, kinematic pairs, motion ranges, and degrees of freedom of each component, and setting motion constraints for each component to limit its motion range, direction, and relative position, so as to obtain a virtual simulation model that can truly reflect the dynamic behavior and physical interactions of the equipment.

[0029] S30: Set simulation parameters and test scenarios, and based on the simulation parameters and test scenarios, run the virtual simulation model to generate simulation test results.

[0030] Specifically, set simulation parameters and test scenarios, including setting simulation time step, calculation accuracy, physical simulation parameters, and initial state parameters of each component according to the equipment design requirements and operating characteristics, and at the same time construct test scenarios covering normal production conditions, load changes, and abnormal state simulations. Start the virtual simulation model for simulation, and collect the motion data, sensor feedback, and control response data of each component in real time during the operation process. Finally, perform time series recording, fluctuation trend analysis, and deviation comparison on the collected data to generate comprehensive simulation test results.

[0031] S40: Adjust the on-site commissioning plan of the cutting and punching device based on the simulation test results.

[0032] Specifically, adjust the on-site commissioning plan of the cutting and punching equipment based on the simulation test results, including deeply analyzing the operation data to identify key performance indicators such as the dynamic response of the equipment, energy consumption, fault triggering, and control logic deviation. By comparing the preset working logic with the actual simulation output, formulate targeted optimization measures, adjust the control logic, motion parameters, and structural configuration. At the same time, combine the fault prediction and early warning mechanism and the working condition data of actual on-site production to correct the commissioning plan, so as to ensure that the on-site commissioning plan can achieve the best operating state of the equipment in actual production.

[0033] By adopting the above technical solution, by obtaining the structural data of the cutting and punching equipment and constructing a preliminary virtual simulation model based on this data, the geometric dimensions and connection methods of each mechanism of the equipment can be accurately captured, thus providing a precise basis for model establishment and ensuring the reliability of subsequent simulation results; by defining the component characteristics of each component in the preliminary virtual simulation model, including physical properties, motion relationships, constraint conditions, and preliminary setting of control logic, the dynamic behavior and interaction of each component can be detailedly reflected, so that the virtual simulation model highly matches the actual equipment and improves the simulation accuracy; by setting simulation parameters and test scenarios and running the virtual simulation model based on this to generate simulation test results, key operation data can be collected in real time under different working conditions, providing detailed data support for equipment performance evaluation and potential problem diagnosis, thus laying a foundation for the scientific adjustment of the on-site commissioning plan; by adjusting the on-site commissioning plan based on the simulation test results, the deficiencies in equipment control and structural design can be quickly identified and corrected, thus shortening the commissioning cycle, reducing the on-site commissioning risk, and improving the overall operation efficiency and stability of the equipment.

[0034] In one embodiment, as Figure 2 shown, in step S10, that is, based on the structural data, construct a preliminary virtual simulation model of the cutting and punching equipment, which specifically includes: S11: Extract the three-dimensional geometric data of each mechanism from the structural data, and the three-dimensional geometric data includes dimensions, shapes, and connection methods.

[0035] Specifically, parse and extract the three-dimensional geometric data of each mechanism from the structural data. These data include the dimensions, shapes, and connection methods of each mechanism. For example, by parsing the parameters stored in the CAD file and the actual part contour information obtained by a three-dimensional scanner, organize these digitalized data into standardized model data to ensure that the length, width, height, surface contour, and assembly interface information of each part are accurately recorded.

[0036] S12: Based on the three-dimensional geometric data, construct a preliminary virtual model of the cutting and punching equipment.

[0037] Specifically, based on the three-dimensional geometric data, a preliminary virtual model of the cutting and punching equipment is constructed using three-dimensional modeling software. The extracted geometric data is input into the modeling platform, and through precise positioning and mesh division, digital models of each mechanism are generated according to the actual assembly sequence and connection method, thereby forming a preliminary virtual model that can reflect the true dimensions and relative positions of each component.

[0038] In one embodiment, as Figure 3 shown, in step S20, that is, defining the component characteristics of each component in the preliminary virtual simulation model to obtain the virtual simulation model, specifically including: S21: Define the physical properties of each component in the preliminary virtual simulation model. The physical properties include mass, inertia, and friction coefficient.

[0039] Specifically, by analyzing the dimensions, materials, and assembly relationships of each component in the read structural data, and using engineering standards and physical formulas (for example, determining mass through static balance and mass distribution formulas, calculating the moment of inertia through integral methods, and determining the friction coefficient through experimental data and theoretical models), these parameters are accurately calculated and then input into the three-dimensional modeling software, thereby endowing each component with accurate physical properties to ensure that the dynamic behavior and interaction of each component during the actual operation of the equipment can be truly reflected in the subsequent simulation process.

[0040] S22: Establish the motion relationships and constraint conditions between each component in the preliminary virtual simulation model, and set motion constraints for each component. The constraint conditions include the motion trajectories, kinematic pairs, motion ranges, and degrees of freedom of each component, and the motion constraints include restricting the motion range, direction, and relative position of the component.

[0041] Specifically, according to the spatial positions and assembly relationships of each component recorded in the extracted three-dimensional geometric data, the relative motion relationships between the components are established in the three-dimensional modeling software using kinematic principles. At the same time, by setting the kinematic pair parameters (such as the definition of rotational pairs or sliding pairs) and clearly defining the motion trajectories, allowed motion ranges, and degrees of freedom of each component, the connection methods between the components are strictly constrained using the built-in constraint editing function in the software to limit their motion ranges, motion directions, and relative positions, so as to ensure that the motion behaviors in the virtual simulation model are completely consistent with the assembly and design requirements of the actual equipment. For example, the cutting and punching equipment includes a conveyor line, and punching mechanism 1, punching mechanism 2, cutting mechanism 1, cutting mechanism 2, material cutting mechanism 1, and material cutting mechanism 2 arranged in sequence along the conveyor line. Punching mechanism 1 has a YZ axis that can be horizontally translated and vertically lifted, can punch normal round holes and round holes with offsets, and can move up and down. Punching mechanism 2 has an XYZ axis that can be vertically lifted, horizontally translated, and longitudinally translated, can punch normal round holes and round holes with offsets, and can move up and down and left and right; cutting mechanism 1 and cutting mechanism 2 have an XZ axis that can be horizontally translated and vertically lifted; material cutting mechanism 1 and material cutting mechanism 2 have an XZ axis that can be horizontally translated and vertically lifted, and the center point of the cutting tool is always on the center line through mechanical control.

[0042] S23: According to the structural data and the preset equipment working logic, create and load a PLC simulation program to define the control logic of each component in the preliminary virtual simulation model. The control logic includes controlling the action sequence, timing control, and state switching of each component.

[0043] Specifically, according to the extracted structural data and the preset equipment working logic, write the corresponding control program using a PLC programming platform and load the program into the virtual simulation model through a simulation tool. Convert the operation process of the equipment into control instructions, set the action sequence, timing control, and state switching conditions of each component, and trigger the next action automatically after the current action is completed by setting logical judgment, delay parameters, and state feedback mechanisms. This process realizes real-time data collection and feedback adjustment by comparing on-site debugging data and simulation outputs, so as to ensure that the control logic can accurately simulate the actual equipment operation in the simulation environment. For example, in the cutting and punching equipment, iron sheets are input from the feeding end of the conveyor line, punching mechanism 1 and punching mechanism 2 perform punching, the iron sheets are continuously conveyed to cutting mechanism 1 and cutting mechanism 2, cutting mechanism 1 makes a lower-side V cut on the iron sheet, cutting mechanism 2 makes an upper-side V cut on the iron sheet, the iron sheets are continuously conveyed to material cutting mechanism 1 and material cutting mechanism 2, material cutting mechanism 1 and material cutting mechanism 2 cooperate to cut the iron sheets into segments, and finally are conveyed to the receiving platform at the discharging end of the conveyor line.

[0044] In one embodiment, as Figure 4As shown, before step S23, that is, before creating and loading a PLC simulation program according to the structural data and the preset device working logic for defining the control logic of the device, the simulation test method for a cutting and punching device further includes: S2301: Obtain production requirements, and determine the preset device working logic according to the production requirements. The production requirements include production rhythm, process flow, and product quality standards.

[0045] Specifically, by collecting historical on-site production records, product specifications, process flow documents, and relevant measurement data, obtain the key parameters of the device during actual production, and use the monitoring device and historical data to statistically analyze the production rhythm, process flow, and product quality standards. After organizing these data into structured information, use data conversion algorithms to calculate the time requirements and operation intervals of each process step, so as to determine the preset device working logic. This preset working logic clearly stipulates the start sequence and delay conditions of each process such as punching, cutting, and material cutting to ensure the continuous and stable operation of the device during actual production.

[0046] In an embodiment, as Figure 5 shown, in step S30, that is, setting simulation parameters and test scenarios, running the virtual simulation model based on the simulation parameters and test scenarios, and generating simulation test results, specifically including: S31: Set simulation parameters according to the device design requirements and operating characteristics. The simulation parameters include simulation time step, calculation accuracy, and initial state parameters of each component.

[0047] Specifically, through data collection and analysis of the device design requirements and operating characteristics, accurately measure the initial state of each component of the device using historical on-site test data, manufacturing standards, and theoretical models, and use the step-by-step decreasing method to determine the simulation time step to ensure that the numerical calculation can truly reflect the dynamic response of the device while meeting the accuracy requirements. At the same time, determine the initial position, initial velocity, and initial state identifier of each component according to the static measurement data of the actual device, and set the calculation accuracy using the numerical error tolerance calculation method. For example, by gradually reducing the time step and observing the convergence and stability of the simulation results, the initial state parameters of each component are set, so that the virtual simulation model can truly reflect the device design requirements and actual operating characteristics during the simulation process.

[0048] S32: Construct a test scenario. The test scenario includes normal production conditions, load changes, and abnormal state simulations.

[0049] Specifically, by retrieving historical production data and on-site test records, combining with the observation of the continuous operation mode of each component under normal production conditions, multiple test scenarios are constructed using data analysis methods, including normal production conditions under standard operations and extreme conditions such as simulated load mutations and abnormal states. By adjusting input variables and process parameters, full-coverage simulation of the operating states of the equipment under different production conditions is achieved, thereby providing a multi-angle test environment for equipment performance evaluation.

[0050] S33: Based on the simulation parameters and test scenarios, start the virtual simulation model for simulation, and collect the operation data during the operation of the virtual simulation model in real time.

[0051] Specifically, according to the previously set simulation parameters and the constructed test scenarios, start the operation of the virtual simulation model. At the same time, use the real-time data acquisition module to monitor the movement of each component, sensor output, and PLC control response. Save the key operation data in the form of a continuous time series through data recording software. For example, collect movement data, energy consumption data, and status signals within each time step to ensure that the collected data can completely and accurately reflect the operation of the model under each test scenario.

[0052] S34: Analyze and process the operation data to generate simulation test results. The analysis and processing include time series recording, fluctuation trend analysis, and deviation comparison.

[0053] Specifically, integrate and process the collected operation data using data analysis software. Through continuous time series recording, use the fluctuation trend analysis algorithm and statistical methods to draw trend charts and calculate the percentage of deviation for each key parameter. For example, compare the difference between the preset standard and the actual operation data to identify equipment performance changes and abnormal signals, thereby generating comprehensive simulation test results including equipment dynamic response, energy consumption analysis, fault trigger frequency, and control logic deviation, providing a scientific basis for optimizing the on-site commissioning plan.

[0054] In one embodiment, as Figure 6 shown, the simulation test method for the cutting and punching equipment further includes: S50: Introduce a fault prediction and early warning mechanism during the simulation test, set up an equipment fault detection module, and when an abnormal state of the virtual simulation model or a key parameter exceeds the preset parameter range is detected, trigger an alarm signal and record the abnormal data.

[0055] Specifically, during the operation of the virtual simulation model, key parameters such as the motion data and current of each component are collected in real time, and the threshold comparison of each parameter is carried out by using mathematical models and statistical analysis methods. The normal fluctuation range of each parameter is calculated and calibrated by combining historical data and preset standards. By setting a continuous monitoring program, the data is compared in real time. When the instantaneous value or trend data of a certain key parameter exceeds the preset range, an alarm is immediately triggered through a simulation signal, and the specific time of the anomaly occurrence, the value of the abnormal parameter, and its change trend are recorded in the data acquisition module. At the same time, it is stored as a standard log file in the data record format.

[0056] S60: Use virtual reality technology to visually display the simulation test process of the virtual simulation model, and provide a user interaction interface for real-time monitoring of the equipment operation status of the virtual simulation model and real-time adjustment of the simulation test process of the virtual simulation model.

[0057] Specifically, by converting the real-time operation data of each component in the virtual simulation model into three-dimensional graphics and dynamic charts, and using augmented reality or virtual reality display devices to present these graphic data in the operation interface, and realizing interactive operations through touch screen or gesture recognition technology, so that the debugging personnel can observe the motion status of each component of the equipment, the changes of key parameters, and the fault alarm information in real time. At the same time, adjustment instructions are directly input in the visualization interface, such as modifying the simulation time step, adjusting the calculation accuracy, or updating the sensor feedback threshold, and the adjustment effect is verified through real-time data feedback, so as to realize the real-time monitoring and dynamic adjustment of the simulation test process, and improve the debugging efficiency and on-site adaptability.

[0058] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
