Detailed Implementation

[0017] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0018] In related technologies, the processing of automotive cold stamping die inserts relies on manual transfer and clamping, requiring manual straightening and centering on machine tools. This not only occupies equipment resources but also reduces production capacity. The manual verification of workpiece information poses quality risks, and it is impossible to store workpieces to be processed in batches, making it difficult to support the simultaneous operation of multiple machine tools. After processing, manual inspection is required, which cannot achieve closed-loop quality management. Processing and self-inspection information rely on paper records, resulting in data untraceability. In addition, the accumulation of iron filings in screw holes is serious, and manual cleaning is time-consuming, which to some extent affects production efficiency.

[0019] The following description, with reference to the accompanying drawings, outlines a method, apparatus, and machine tool for machining automotive cold stamping dies according to embodiments of this application. Addressing the issues mentioned in the background art regarding the low efficiency, error-proneness, and difficulty in achieving automatic detection and closed-loop management in automotive cold stamping die workpiece machining due to reliance on manual verification of drawings, manual parameter input, and sub-centering, this application provides a method for machining automotive cold stamping dies. In this method, in response to a user's first interactive action, a workpiece pre-adjustment interface for the automotive cold stamping die is triggered. The pre-adjustment interface includes a first display area displaying machining specifications, a second display area displaying workpiece information, a third display area displaying user-input pre-adjustment data, and a fourth display area displaying the machining task status. Subsequently, responding to the user's second interactive action triggered by the processing specifications and actual measurements, the system acquires pre-adjusted data and processes the automotive cold stamping die workpiece according to the acquired workpiece processing data. After processing, online inspection and automatic centering operations are performed on the workpiece based on the pre-adjusted data. This effectively avoids manual verification of drawings and manual input of pre-adjusted parameters, reduces manual intervention in centering operations, improves processing efficiency and accuracy, and provides a data foundation for subsequent online inspection and automatic centering, thereby supporting the automation of the processing process and closed-loop quality management. This solves the problems of low processing efficiency and high error rates caused by reliance on manual centering in automotive cold stamping die workpiece processing.

[0020] Specifically, Figure 1 This is a flowchart illustrating a workpiece processing method for an automotive cold stamping die, as provided in an embodiment of this application.

[0021] like Figure 1 As shown, the workpiece processing method of this automotive cold stamping die includes the following steps: In step S101, in response to the user's first interactive action, the workpiece pre-adjustment interface of the automotive cold stamping die is triggered. The workpiece pre-adjustment interface includes a first display area, a second display area, a third display area, and a fourth display area. The first display area displays the processing specification sheet, the second display area displays the workpiece information, the third display area displays the pre-adjustment data input by the user, and the fourth display area displays the processing task status.

[0022] The first interactive action refers to the operation of the operator entering the workpiece pre-adjustment interface after starting the pre-adjustment software; the first display area refers to the area used to display the processing specification sheet; the second display area refers to the area used to display the workpiece information; the third display area refers to the area used to display the pre-adjustment data input by the user; the fourth display area refers to the area used to display the processing task status; the processing specification sheet refers to the standardized programming processing instruction template; the workpiece information refers to the identification data used to uniquely identify the workpiece; the pre-adjustment data refers to the parameters filled in by the user in the pre-adjustment software according to the processing specification sheet and the measured values; the processing task status refers to the current task execution status of the workpiece in the flexible line, such as pending processing, processing, or completed.

[0023] It is understood that the embodiments of this application can centrally display processing specifications, workpiece information, pre-adjustment data and task status through a structured pre-adjustment interface, enabling operators to quickly and accurately complete the input of pre-adjustment parameters, avoiding manual searching of drawings and programs, eliminating quality problems caused by misreading information, and improving pre-adjustment efficiency and accuracy.

[0024] In some embodiments, the processing specification includes a first reference value, a second reference value, a third reference value, a fourth reference value, and a workpiece processing technology. The first reference value represents the absolute coordinate values ​​of the fixture reference hole and the workpiece center to the process plate reference hole. The second reference value represents the reference value of the workpiece in the measurement direction. The third reference value represents the zero point coordinate of the workpiece. The fourth reference value represents the reference shim value.

[0025] The first reference value refers to the absolute coordinates of the fixture reference hole and the workpiece center to the process plate reference hole, used for online detection of the position of the positioning insert on the tray; the second reference value refers to the reference value of the workpiece in the measurement direction, used for online detection of the X and Y reference of the measuring insert; the third reference value refers to the zero point coordinate of the workpiece, used to determine the Z-axis tool setting method; the fourth reference value refers to the reference shim value, used to set the shim parameters when clamping the workpiece; the process plate refers to the standardized clamping plate used to fix the insert; the workpiece machining process refers to the machining method and process requirements for the workpiece, used to guide the setting of preset parameters and subsequent machining.

[0026] It is understood that the embodiments of this application can standardize the processing index into structured data containing first to fourth reference values ​​and processing technology, providing a clear and unified input basis for pre-adjustment, ensuring that online detection can accurately find the workpiece position, establish a coordinate system and perform automatic sub-centering, avoiding manual straightening, and achieving consistency and repeatability of clamping and processing.

[0027] Specifically, the third reference value represents the zero-point coordinates of the workpiece, and its position depends on the workpiece clamping posture. To unify the Z-axis tool setting logic, this invention defines the following center standardization rule: after the workpiece is clamped, if the Z0 surface of the workpiece is at the top, the Z-axis tool setting method is top-to-top. For example, as... Figure 2 As shown, if the workpiece coordinate system is in the lower left corner, then the Z-axis tool setting methods for the back side (06SX-BM), viewing angle 180 (06SX-S180), and viewing angle 270 (06SX-S270) are all top-aligned. When the workpiece is clamped and its Z0 surface is at the bottom, the Z-axis tool setting method is bottom-aligned. For example, as... Figure 3 As shown, if the workpiece coordinate system is in the lower left corner, then the Z-axis tool setting methods for the front (06SX-ZM), viewing angle 0 (06SX-S0), and viewing angle 90 (06SX-S90) are all bottom-setting. And as... Figure 4 As shown, the specified point is the location that needs to be given in the program, and it will change depending on the workpiece. For example... Figure 5 As shown, the fixed points are pre-designed locations and will not change due to different workpieces.

[0028] Furthermore, such as Figure 6 As shown, the machining specification sheet includes four key parameters: The first reference value represents the absolute coordinates (distinguishing between positive and negative values) of the fixture reference hole and the workpiece center to the process plate reference hole, used for online detection of the position of the positioning insert on the tray; the second reference value represents the reference value of the workpiece in the measurement direction, i.e., the blank size, used for online detection of the X and Y reference of the measuring insert; the third reference value represents the zero point coordinate (Z value) of the workpiece, used for online detection of setting Z0. When the Z0 surface is located on the top surface after the workpiece is clamped, the Z-axis tool setting method is top setting, and the tool is set through the specified point; the fourth reference value represents the reference shim value, used to set the shim parameter when the workpiece is clamped.

[0029] In some embodiments, the workpiece information includes at least one of the following: workpiece barcode, item number, drawing number, part number, and name.

[0030] Among them, the workpiece barcode refers to the machine-readable code attached to the workpiece, which is used to automatically identify the workpiece; the project number refers to the unique number of the R&D or production project to which the workpiece belongs; the drawing number refers to the number of the engineering drawing corresponding to the workpiece, which is used to associate design data; the part number refers to the unique part number of the workpiece in the mold assembly; and the name refers to the standard name of the workpiece.

[0031] It is understood that the embodiments of this application can eliminate the manual confirmation process by storing workpiece information in a structured form such as barcode, project number, drawing number, part number or name, and combining it with digital media for automatic identification, thereby avoiding quality risks such as misassembly and mixing of materials, and realizing rapid and accurate traceability of workpiece identity.

[0032] In step S102, in response to the user's second interactive action, pre-adjusted data is obtained from the second display area, wherein the user triggers the second interactive action based on the processing index and actual measurement values ​​displayed in the first display area.

[0033] The second interactive action refers to the user's operation of inputting and confirming the pre-adjustment data based on the processing index and actual measurement values ​​in the first display area on the pre-adjustment interface.

[0034] It is understood that the embodiments of this application can ensure that the pre-adjustment parameters are consistent with the process requirements by associating the input of the pre-adjustment data with the processing index and the actual measurement value, and triggering data acquisition with user interaction actions, thereby avoiding problems such as clamping or sub-center errors caused by human misjudgment.

[0035] In some embodiments, the pre-adjustment data includes the fixture reference hole coordinates set according to a first reference value, the blank size set according to a second and a third reference value, the shim value set according to a fourth reference value, and the offset set according to the workpiece machining process.

[0036] Among them, the fixture reference hole coordinates refer to the coordinate values ​​used for online detection and positioning of the insert on the tray; the blank size refers to the size values ​​used for online detection and measurement of the insert's X and Y axis references; the shim height value refers to the clamping height parameter set according to the fourth reference value; and the offset refers to the machining position correction parameter set according to the workpiece machining process.

[0037] It is understood that, in the embodiments of this application, by specifying the pre-adjustment data as the coordinates of the fixture reference hole, the blank size, the shim value and the offset set based on the first to fourth reference values ​​and the processing technology, the online detection system can automatically complete the workpiece positioning, reference establishment and sub-centering without manual straightening, thus achieving automated clamping and processing.

[0038] Specifically, Figure 7The workpiece pre-adjustment interface was demonstrated, comprising four display areas: the first area displays the machining specifications, including the first, second, third, and fourth reference values, and the workpiece machining process; the second area displays workpiece information, including the workpiece barcode, project number, drawing number, part number, and name; the third area displays user-input pre-adjustment data, including fixture reference hole coordinates, blank dimensions, shim height, and offset; and the fourth area displays the machining task status. Pre-adjustment via the developed software eliminates the need for on-site drawings and manual program searches, preventing quality issues caused by pre-adjustment errors.

[0039] In step S103, the workpiece processing data of the automotive cold stamping die is obtained, the workpiece of the automotive cold stamping die is processed according to the workpiece processing data, and after the processing is completed, the workpiece is subjected to online inspection and automatic centering operation according to the pre-adjusted data.

[0040] Among them, automotive cold stamping dies refer to dies used for stamping and forming automotive body panels, and their inserts are the workpieces being processed; workpiece processing data refers to digital data used to control the machine tool to process the workpiece; automatic centering refers to the operation of automatically aligning the workpiece coordinate system center with the machine tool processing center.

[0041] It is understood that the embodiments of this application can automatically process the workpiece processing data of the automotive cold stamping die insert, and perform online detection and automatic centering based on the pre-adjusted data after processing, avoiding manual straightening and realizing automated clamping and positioning and closed-loop control of processing quality.

[0042] In some embodiments, the workpiece processing data includes workpiece model data and workpiece processing technology. Processing the workpiece of the automotive cold stamping die based on the workpiece processing data includes: acquiring the manufactured workpiece reference entity and workpiece blank data; performing anomaly detection on the workpiece blank data based on the workpiece reference entity; after the anomaly detection of the workpiece blank passes, processing the workpiece blank according to the workpiece model data and workpiece processing technology; acquiring the actual size data of the workpiece blank; if the actual data matches the preset reference size data, completing the processing of the workpiece blank; and controlling the robot to transport the processed workpiece.

[0043] Among them, workpiece model data refers to the data used to process the workpiece blank; workpiece reference entity refers to the fabricated entity used to detect anomalies in the workpiece blank data; workpiece blank data refers to the initial state data of the workpiece to be processed; actual size data refers to the actual size of the workpiece blank obtained after processing; and reference size data refers to the pre-set size standard used for comparison with the actual size data.

[0044] It is understood that the embodiments of this application can perform anomaly detection on blank data based on workpiece reference entity, and after the detection is passed, process according to workpiece model data and processing technology, and then compare the actual size data with the reference size data to determine the completion of processing, thereby realizing blank screening before processing, automation of processing process and automatic determination of processing results, and avoiding defective products from flowing into subsequent processes.

[0045] In some embodiments, performing online inspection and automatic centering operations on the workpiece based on pre-adjusted data during processing includes: measuring the angle of the workpiece based on the pre-adjusted data; compensating the angle of the workpiece based on the angle measurement results; and performing automatic centering operations on the workpiece after angle compensation.

[0046] Angle compensation refers to the correction operation performed on the workpiece based on the angle measurement results.

[0047] It is understood that, according to the embodiments of this application, angle measurement and angle compensation can be performed based on the pre-adjusted data before automatic centering is executed, so that the workpiece coordinate system is aligned with the machining program, eliminating the need for manual straightening and achieving high-precision automatic clamping and positioning.

[0048] In some embodiments, after controlling the robot to transport the processed workpiece, the method further includes: controlling a cleaning device within the machine tool to perform at least one cleaning action on the machine tool.

[0049] The cleaning work includes a primary cleaning of the machine tool's internal fan and a secondary cleaning using specialized cleaning equipment to remove iron filings accumulated in the screw holes.

[0050] It is understood that, in the embodiments of this application, after the robot has transported the processed workpiece, the cleaning equipment inside the machine tool can be controlled to perform cleaning actions to remove residual iron filings, reduce manual cleaning time, and improve production efficiency.

[0051] Specifically, such as Figure 8 As shown, the specific process for machining automotive cold stamping dies includes the following steps: In step 801, the workpiece model data and workpiece processing technology are obtained.

[0052] In step 802, the workpiece machining data is imported into the programming software.

[0053] In step 803, a workpiece reference entity is created based on the workpiece machining data.

[0054] In step 804, input the workpiece blank data.

[0055] In step 805, anomaly detection and judgment are performed on the workpiece blank data based on the workpiece reference entity.

[0056] In step 806, if an abnormality is found, the abnormal status is promptly reported.

[0057] If there are no abnormalities in step 807, continue to design the clamping screw holes.

[0058] In step 808, the measurement point at the top of the back is specified.

[0059] In step 809, an auxiliary surface is created.

[0060] In step 810, unnecessary programs are closed.

[0061] In step 811, the program calculates and checks; if there is an abnormal program, it is reprocessed and returned to step 809.

[0062] In step 812, the program is uploaded to the program library.

[0063] In step 813, the workpiece is pre-adjusted according to the processing specifications.

[0064] In step 814, it is determined whether the actual size data of the workpiece blank conforms to the preset reference size data.

[0065] In step 815, if an abnormality exists, the abnormal workpiece is prohibited from being processed.

[0066] If there are no abnormalities in step 816, the robot will transport the workpiece to the automated warehouse.

[0067] In step 817, the AGV (Automated Guided Vehicle) transports the workpiece to the lineside warehouse.

[0068] In step 818, the central control system schedules the production of workpieces.

[0069] In step 819, the equipment performs cutting operations to process the workpiece.

[0070] In step 820, online workpiece inspection and automatic sorting operations are performed on the workpiece using an online probe.

[0071] In step 821, the central control system makes a judgment and gives a result. Unqualified workpieces are reworked and returned to step 818.

[0072] In step 822, qualified workpieces are transported back to the automated warehouse by AGV.

[0073] In step 823, the workpiece is unloaded and visually inspected. If there is an abnormal workpiece, the programming team checks the processing data and program items, and then returns to step 802.

[0074] In step 824, the final step is to transfer the workpiece to the next process.

[0075] It is understandable that the embodiments of this application effectively prevent unqualified blanks from entering the processing flow through automatic screening of workpiece blank anomalies. Pre-adjustment based on processing specifications eliminates errors caused by manual verification of drawings and manual parameter input. Simultaneously, online detection and automatic sub-centering replace manual straightening, significantly improving clamping accuracy and efficiency. The combination of AGVs and robots enables automatic workpiece flow, supporting the synchronous operation of multiple machine tools. Closed-loop management of processing data throughout the entire process ensures traceability of operations and verifiable results. Automatic interception or rework of abnormal workpieces ensures consistency in processing quality.

[0076] According to the workpiece processing method for automotive cold stamping dies proposed in this application, in response to a user's first interactive action, a workpiece pre-adjustment interface for the automotive cold stamping die is triggered. The pre-adjustment interface includes a first display area showing the processing specifications, a second display area showing workpiece information, a third display area showing user-input pre-adjustment data, and a fourth display area showing the processing task status. Subsequently, in response to a user's second interactive action triggered based on the processing specifications and actual measurement values, pre-adjustment data is acquired, and the workpiece of the automotive cold stamping die is processed according to the acquired workpiece processing data. After processing, online inspection and automatic sub-centering operations are performed on the workpiece based on the pre-adjustment data. This effectively avoids manual verification of drawings and manual input of pre-adjustment parameters, reduces manual intervention in sub-centering operations, improves processing efficiency and accuracy, and provides a data foundation for subsequent online inspection and automatic sub-centering, thereby supporting automation and closed-loop quality management of the processing process. Thus, it solves the problems of low processing efficiency and high error rates caused by reliance on manual sub-centering in automotive cold stamping die workpiece processing.

[0077] Next, referring to the accompanying drawings, a workpiece processing apparatus for automotive cold stamping dies according to an embodiment of this application is described.

Thus, it solves the problems of low processing efficiency and high error rate caused by reliance on manual sub-centering in automotive cold stamping die workpiece processing.
