[0070] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0071] The punching method of the ventral punching machine provided in this application embodiment can be applied to, for example... Figure 1 The application environment shown includes a computer device associated with the CNC system, an operating platform equipped with a ventral punching machine, and a sheet metal to be punched (such as an automotive longitudinal beam). The CNC system deploys the relevant data program for the ventral punching method. The sheet metal moves on the operating platform, and the ventral punching machine performs the punching operation at the target hole position on the sheet metal. The computer device associated with the CNC system determines the initial hole position of the punching machine in the sheet metal; controls the sheet metal to be punched to move in a first direction until the punching machine is positioned at the initial hole position; determines the offset of the sheet metal to be punched in a second direction when the punching machine is positioned at the initial hole position; performs at least one position compensation operation on the initial hole position based on the offset to obtain the target hole position; and controls the punching machine to perform the punching operation based on the target hole position. The computer device associated with the CNC system can be, but is not limited to, various personal computers, laptops, smartphones, tablets, etc.

[0072] Before describing in detail the punching method of the ventral punching machine provided in the embodiments of this application, the structure of the ventral punching machine will be described first. In an exemplary embodiment, such as... Figure 2 As shown, the ventral punching machine includes, in addition to the punching main unit, a drive motor, a servo motor, and a magnetic scale. The drive motor is used to drive the sheet metal to be punched to move in a first direction based on a received first control command. The servo motor is used to drive the punching main unit to move in a second direction based on a received second control command. The punching main unit is used to perform the punching operation at the target hole position on the sheet metal to be punched. The magnetic scale is used to determine a compensation amount based on the displacement of the sheet metal to be punched in the second direction to assist the servo motor in driving the punching main unit to move to the target hole position. It should be noted that, in order to improve punching efficiency, multiple punching main units can be used.

[0073] In one exemplary embodiment, such as Figure 3 As shown, a punching method for a ventral punching machine is provided, which is applied to... Figure 1 Taking the computer equipment belonging to the CNC system as an example, the explanation includes the following steps 302 to 310. Wherein:

[0074] Step 302: Determine the initial hole position of the punching host in the plate to be punched; the initial hole position includes a first component in a first direction and a second component in a second direction, the first direction is perpendicular to the second direction and the first direction is consistent with the moving direction of the plate to be punched.

[0075] In practice, the CNC program provided by the CNC system uses the movement direction of the sheet metal to be punched on the operating platform as the first direction, i.e., the X-axis direction, and the direction perpendicular to this first direction as the second direction, i.e., the Y-axis direction. The CNC system first reads the initial hole positions in the sheet metal to be punched, which are the initial hole positions calculated by the CNC system. The hole positions are usually represented by coordinates, where the values ​​in the first direction are the first component, and the values ​​in the second direction are the second component.

[0076] Step 304: Control the plate to be punched to move in the first direction until the punching host is positioned at the initial hole position.

[0077] In actual implementation, the CNC program sends a plate movement command to the drive motor that is electrically connected to the operating platform. Based on the plate movement command, the drive motor controls the plate to be punched to move along the X-axis until the punching host is positioned at the initial hole position.

[0078] Step 306: Determine the offset of the sheet metal to be punched in the second direction when the punching host is positioned at the initial hole position.

[0079] In actual implementation, during the process of controlling the movement of the plate to be punched in the X-axis direction, there will be an offset in the Y-axis direction. After the CNC system positions the punching host to the initial hole position, it can read the offset of the plate to be punched in the second direction through a measuring device.

[0080] Step 308: Based on the offset, perform at least one position compensation operation on the initial hole position to obtain the target hole position.

[0081] In actual implementation, in order to compensate for the offset in the Y-axis direction, the CNC system can perform one or more position compensation operations on the determined initial hole position. That is to say, the initial hole position is used as the coarse positioning position of the punching machine. Since the plate to be punched has an offset in the Y-axis direction during the movement, one or more position compensation operations can be performed on the coarse positioning position to obtain the target hole position. In other words, the target hole position is obtained by position compensation on the initial hole position.

[0082] Step 310: Control the punching host to perform punching operation based on the target hole position.

[0083] In practice, the CNC system controls the punching machine to perform punching operations on the sheet metal to be punched at the target control position. The same steps 202-210 are performed at all other punching positions to obtain a sheet metal that has undergone one or more punching operations.

[0084] In the aforementioned punching method of the ventral punching machine, the initial hole position of the punching host in the plate to be punched is determined; the plate to be punched is controlled to move in a first direction consistent with the moving direction of the plate to be punched until the punching host is positioned at the initial hole position; the offset of the plate to be punched in a second direction perpendicular to the first direction is determined when the punching host is positioned at the initial hole position; based on the offset, at least one position compensation operation is performed on the initial hole position to obtain the target hole position; and the punching host is controlled to perform the punching operation based on the target hole position. This improves the punching accuracy of the ventral punching machine.

[0085] In one exemplary embodiment, such as Figure 4 As shown, based on the offset, at least one position compensation operation is performed on the initial hole position to obtain the target hole position, including steps 402 to 408. Wherein:

[0086] Step 402: Determine the first compensation amount based on the offset.

[0087] In actual implementation, the magnetic scale included in the ventral punching machine can provide corresponding compensation for the offset of the sheet metal to be punched on the Y-axis during the movement. For ease of distinction, the compensation in this step is called the first compensation.

[0088] Step 404: Determine the second compensation amount for the punching host to move based on the first compensation amount.

[0089] In actual implementation, the CNC system moves the punching machine based on the first compensation amount. At this time, the CNC system reads the second compensation amount indicated on the magnetic scale again to determine the target hole position based on the first and second compensation amounts.

[0090] Step 406: Determine the difference between the first compensation amount and the second compensation amount.

[0091] In actual implementation, the CNC system deployed in the computer equipment determines the difference between the two compensation amounts, that is, the difference between the first compensation amount and the second compensation amount.

[0092] Step 408: Based on the difference and the difference threshold, perform at least one position compensation operation on the initial hole position to obtain the target hole position.

[0093] In actual implementation, different types of punching processes are associated with different process tolerances, i.e. different difference thresholds. The CNC system deployed in the computer equipment obtains the difference threshold corresponding to the current punching process, compares the two, and then performs a position compensation operation on the initial hole position based on the comparison result to obtain the final target hole position.

[0094] In this embodiment, the compensation operation for the hole position is determined by the difference between the first compensation amount and the second compensation amount, thereby improving the accuracy of locating the target hole position.

[0095] In an exemplary embodiment, a position compensation operation is performed at least once on the initial hole position based on the difference and a difference threshold to obtain the target hole position, including: comparing the difference with the difference threshold; if the difference is less than the difference threshold, a position compensation operation is performed on the initial hole position based on a first compensation amount to obtain the target hole position; if the difference is greater than or equal to the difference threshold, a position compensation operation is performed on the initial hole position based on the first compensation amount and a second compensation amount to obtain the target hole position.

[0096] In actual implementation, if the difference is less than the difference threshold, a position compensation operation is directly performed on the second component of the initial hole position in the Y-axis direction to obtain the target positioning position; if the difference is greater than the difference threshold, a compensation operation is performed on the punching position of the previous punching host based on the new compensation amount to obtain the final target hole position.

[0097] In this embodiment, the requirements for performing position compensation operations are determined by the difference and the difference threshold. In this way, compensation can be performed as needed according to actual requirements, ensuring the timeliness and accuracy of the compensation operation.

[0098] In an exemplary embodiment, a position compensation operation is performed on the initial hole position based on a first compensation amount to obtain the target hole position, including: weighting and summing the second component of the initial hole position with the first compensation amount to obtain the compensated second component; and determining the target hole position based on the first component and the compensated second component.

[0099] In actual implementation, when the difference is less than the difference threshold, the specific implementation process of the position compensation operation is as follows: the second component of the initial hole position in the Y-axis direction is weighted and summed with the first compensation amount to obtain the compensated second component; the first component is used as the component of the target hole position in the X-axis direction, and the compensated second component is used as the component of the target hole position in the Y-axis direction.

[0100] In this embodiment, the position compensation operation for the second component in the Y-axis direction can not only reduce the computational cost of the position compensation operation, but also ensure the accuracy of the position compensation operation.

[0101] In an exemplary embodiment, based on a first compensation amount and a second compensation amount, performing at least one position compensation operation on the initial hole position to obtain the target hole position includes: adjusting the second compensation amount at least once according to a preset adjustment step size until the difference between the second compensation amount after the last adjustment and the first compensation amount is less than or equal to a difference threshold; performing a weighted summation of the second component of the initial hole position and the second compensation amount after the last adjustment to obtain a compensated second component; and determining the target hole position based on the first component and the compensated second component.

[0102] In actual implementation, when the difference is greater than the difference threshold, the CNC program can adjust the second compensation amount one or more times according to the preset adjustment until the difference between the second compensation amount after the last adjustment and the first compensation amount is less than or equal to the difference threshold. This indicates that it has met the maximum allowable error of the process. At this time, the second component is compensated by weighted summation. Then, the first component of the initial hole position is used as the component of the target hole position in the X-axis direction, and the compensated second component is used as the component of the target hole position in the Y-axis direction. Finally, the target hole position is obtained.

[0103] In this embodiment, when the difference is greater than the difference threshold, the corresponding target hole position is determined through multiple position compensation operations, which can greatly improve the accuracy of hole position determination.

[0104] To illustrate the punching method of the ventral punching machine in this solution, an embodiment is provided below. In this embodiment, the sheet metal to be punched is an automotive longitudinal beam. The ventral punching machine's punching method implements the automotive longitudinal beam process. This method is a secondary positioning method for the ventral punching machine, which ensures the punching accuracy when punching the automotive longitudinal beam through secondary positioning. The ventral punching machine can include two punching main units, a CNC system, and a servo motor, used to control the movement of the main units in the length direction (X) and width direction (Y), respectively. The movement in the width direction (Y) mainly controls the secondary positioning of the main units in this direction. The specific execution process is as follows:

[0105] Firstly, when machining automotive longitudinal beams, a magnetic scale and a servo motor are used to control the punching accuracy of the punching machine in the Y direction. The servo motor controls the punching machine to reach the coordinate position determined by the CNC program. The displacement value indicated by the magnetic scale can be used for longitudinal beam position compensation, controlling the servo motor to complete the first positioning in the Y direction. However, due to the possibility of Y-direction offset during the X-direction transport of the automotive longitudinal beam, the Y-direction position of the punching may deviate. Therefore, the CNC system reads the displacement value indicated by the magnetic scale a second time. If the difference between the two displacement values ​​is greater than the allowable process error, the servo motor position is finely adjusted based on the second reading of the magnetic scale value, improving machining accuracy.

[0106] The fine-tuning of the servo motor position is explained, such as... Figure 5 As shown, based on the hole position coordinates in the CNC program, after the CNC system controls the servo motor to reach the hole position coordinates, the CNC system reads the Y-direction magnetic scale value and compensates the Y-direction coordinate value according to the magnetic scale data. The system then controls the servo motor to precisely position itself to the compensated coordinate position. After reaching the compensated coordinate position, the CNC system reads the Y-direction magnetic scale data a second time. If the error range between the first and second read values ​​is less than ±0.5mm, the main unit performs the drilling operation. If the error is greater than 0.5mm, the system controls the servo motor to reach the compensated coordinate position again, based on the magnetic scale data.

[0107] By applying the embodiments of this application, the secondary positioning method of the ventral punching machine enables the precise processing of automotive longitudinal beam products, supporting the improvement of quality and reduction of costs on the production site.

[0108] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
