Description

Technical Field

[0001] This invention relates to the technical field of automated sheet processing control, and in particular to an automated control method, device and medium for cutting irregularly shaped sheets. Background Technology

[0002] In the field of sheet material processing control technology, when automating the processing of sheet-shaped workpieces with irregular contours, it is usually necessary to first determine the geometric boundary relationship of each processing sheet according to the target contour parameters, then generate the corresponding processing length, and control the processing equipment to complete processing operations such as feeding and cutting.

[0003] In existing technologies, for target contours formed by multiple curved and straight boundary segments, the length parameters of each processing piece are typically determined manually through modeling, calculation, or pre-programmed methods. This approach is prone to problems such as cumbersome parameter calculations, low length generation efficiency, and insufficient processing adaptability when the target contour structure is complex, there are many boundary intersections, and the number of sheets is large. Especially when different processing lengths need to be generated piece by piece along the radial direction of the target contour, the lack of an automatic solution mechanism corresponding to the contour segmentation relationship often makes it difficult to accurately determine the boundary position and length information of each processing piece, thus affecting subsequent processing accuracy.

[0004] In addition, most existing processing control methods focus on processing control of sheets with fixed lengths or regular contours, lacking segmented solution and sheet-by-sheet length generation control for sheets with irregular contours. It is difficult to automatically switch the corresponding boundary solution method according to different contour segments, resulting in a large amount of parameter adjustment during processing, low degree of automation, and is not conducive to improving the processing efficiency and consistency of sheets with complex contours. Summary of the Invention

[0005] To address the problem of automatically determining the processing length during the processing of lung-shaped silicon steel sheets in existing technologies, this application provides an automated control method, apparatus, and medium for cutting irregularly shaped sheets.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] An automated control method for cutting irregularly shaped sheets, the method comprising:

[0008] Obtain the basic parameters corresponding to the lung-shaped silicon steel sheet;

[0009] Based on the aforementioned basic parameters, construct the equations for the inner circle, outer circle, small circle, oblique line, and parallel line;

[0010] Based on the equations of the inner circle, outer circle, small circle, oblique line, and parallel line, the intersection points are solved to obtain the radius information corresponding to multiple segmented reference points, and multiple radius segment intervals are determined according to the radius information corresponding to the multiple segmented reference points.

[0011] Based on the silicon steel sheet thickness parameter in the basic parameters, the target radius corresponding to each silicon steel sheet to be processed is generated one by one, starting from the preset reference radius.

[0012] Based on the radius segmentation interval of the target radius corresponding to the current silicon steel sheet to be processed, the corresponding boundary equation and the material circle equation are selected to find the intersection, and the two target intersection points corresponding to the current silicon steel sheet to be processed are obtained.

[0013] The target chord length is determined based on the intersection of the two targets, and the target arc length is determined based on the target chord length and the target radius.

[0014] The target arc length is determined as the processing length corresponding to the current silicon steel sheet to be processed, and the processing equipment is controlled to process the current silicon steel sheet according to the processing length.

[0015] By adopting the above technical solution, the basic parameters corresponding to the lobe-shaped silicon steel sheet are first obtained, and based on this, inner circle equations, outer circle equations, small circle equations, oblique line equations, and parallel line equations are constructed. This transforms the contour boundary relationship of the lobe-shaped silicon steel sheet into a calculable equation relationship. Then, the radius information corresponding to multiple segmented reference points is obtained by solving the intersection points, and multiple radius segment intervals are determined based on the radius information corresponding to multiple segmented reference points. This provides a clear segmentation basis for radius changes under different contour stages, thereby avoiding reliance on manual trial calculations for each sheet during the overall verification process and improving the accuracy of contour segmentation solutions. Furthermore, based on the silicon steel sheet thickness parameters, the target radius corresponding to each silicon steel sheet to be processed is generated one by one, starting from a preset reference radius, and the corresponding radius segment interval is selected based on the radius segment interval where the target radius is located. The boundary equations are intersected with the material circle equations to obtain two target intersection points corresponding to the current silicon steel sheet to be processed. This allows the geometric boundaries corresponding to different sheet numbers to automatically match the corresponding solution paths, thereby improving the adaptability of the contour solution for each silicon steel sheet to be processed. Then, the target chord length is determined based on the two target intersection points, and the target arc length is determined based on the target chord length and the target radius. This directly transforms the contour boundary relationship into a processing length that can be used for processing control, thereby improving the efficiency and accuracy of processing length determination. Finally, the target arc length is determined as the processing length corresponding to the current silicon steel sheet to be processed, and the processing equipment is controlled to process the current silicon steel sheet according to the processing length. This allows the parameter solution results to directly affect the actual processing process, thereby improving the automation level and processing consistency of the lung-shaped silicon steel sheet processing process.

[0016] Preferably, the basic parameters include the coordinates of the inner circle's center and radius, the coordinates of the outer circle's center and radius, the coordinates of the small circle's center and radius, the angle of the oblique line, the parameters of the parallel line, and the thickness parameter of the silicon steel sheet. These basic parameters are obtained through a human-computer interaction interface.

[0017] By adopting the above technical solution, the basic parameters are limited to the coordinates of the inner circle's center and radius, the coordinates of the outer circle's center and radius, the coordinates of the small circle's center and radius, the angle of the oblique line, the parameters of the parallel line, and the thickness parameters of the silicon steel sheet. These basic parameters are obtained through a human-computer interaction interface. This allows for the centralized input and unified management of the key parameters required for constructing the lung-shaped silicon steel sheet contour, avoiding input confusion and incorrect correspondence caused by scattered parameter sources. At the same time, it facilitates the direct formation of a parameter base that matches the equations of the inner circle, outer circle, small circle, oblique line, and parallel line, thereby improving the standardization of basic parameter acquisition, the convenience of subsequent equation construction, and the stability of the automated control process of the lung-shaped silicon steel sheet.

[0018] Preferably, the step of constructing the equations for the inner circle, outer circle, smaller circle, oblique line, and parallel line based on the basic parameters includes:

[0019] The equation of the inner circle is constructed based on the coordinates of the center of the inner circle and the radius of the inner circle.

[0020] The equation of the outer circle is constructed based on the coordinates of the outer circle's center and the outer circle's radius.

[0021] The equation of the small circle is constructed based on the coordinates of its center and its radius.

[0022] The equation of the oblique line is constructed based on the oblique line angle and the coordinates of the preset intersection point;

[0023] The parallel line equation is constructed based on the parallel line parameters.

[0024] By adopting the above technical solution, the inner circle equation is constructed based on the coordinates of the inner circle's center and radius, the outer circle equation is constructed based on the coordinates of the outer circle's center and radius, the small circle equation is constructed based on the coordinates of the small circle's center and radius, the oblique line equation is constructed based on the oblique line angle and the coordinates of the preset intersection point, and the parallel line equation is constructed based on the parallel line parameters. This allows the circular boundaries, oblique line boundaries, and parallel line boundaries in the lung-shaped silicon steel sheet contour to be converted into corresponding equation expressions, providing a unified calculation basis for different boundary relationships. This facilitates the subsequent simultaneous solution of the intersection points between the boundaries. At the same time, it establishes a clear mapping relationship between the original input parameters and the corresponding boundary equations, thereby improving the accuracy of contour boundary construction, the convenience of subsequent segmented solutions, and the stability of the automated control process of the lung-shaped silicon steel sheet.

[0025] Preferably, the step of solving for the intersection points based on the equations of the inner circle, the outer circle, the smaller circle, the oblique line, and the parallel line to obtain radius information corresponding to multiple segmented reference points, and determining multiple radius segment intervals based on the radius information corresponding to the multiple segmented reference points, includes:

[0026] By solving the equations of the inner circle and the oblique line simultaneously, the first radius information corresponding to the intersection of the inner circle and the oblique line can be obtained.

[0027] By solving the equations of the small circle and the oblique line simultaneously, the second radius information corresponding to the intersection point of the small circle and the oblique line can be obtained.

[0028] Solving the equations of the small circle and the outer circle simultaneously yields the third radius information corresponding to the intersection point of the small circle and the outer circle.

[0029] By solving the equations of the outer circle and the parallel lines simultaneously, the fourth radius information corresponding to the intersection point of the outer circle and the parallel lines is obtained.

[0030] Multiple radius segment intervals are determined based on the first radius information, the second radius information, the third radius information, and the fourth radius information.

[0031] By employing the aforementioned technical solution, and simultaneously solving the equations of the inner circle and the oblique line, the small circle and the oblique line, the small circle and the outer circle, and the outer circle and the parallel line, we can obtain the first radius, second radius, third radius, and fourth radius information corresponding to the boundary changes of the lung-shaped silicon steel sheet contour. Then, based on these first, second, third, and fourth radius information, we determine multiple radius segmentation intervals. This allows us to divide the different stages of change in the lung-shaped silicon steel sheet contour according to the radius size pattern, providing a clear segmentation basis for subsequent boundary solutions corresponding to different target radii. This avoids matching deviations caused by using a uniform solution method for different contour stages, thereby improving the accuracy of radius segmentation determination, the adaptability of subsequent target intersection point solutions, and the stability of lung-shaped silicon steel sheet processing control.

[0032] Preferably, the step of generating the target radius corresponding to each silicon steel sheet to be processed, based on the silicon steel sheet thickness parameter in the basic parameters and starting from a preset reference radius, includes:

[0033] Use the preset reference radius as the initial radius;

[0034] Determine the sheet number corresponding to the silicon steel sheet to be processed;

[0035] The corresponding radius increment is determined based on the sheet number and the silicon steel sheet thickness parameter;

[0036] The initial radius is incremented according to the radius increment to obtain the target radius corresponding to the silicon steel sheet to be processed.

[0037] By adopting the above technical solution, using the preset reference radius as the initial radius, a unified starting reference can be provided for generating the target radius corresponding to each silicon steel sheet to be processed. The sheet number corresponding to the current silicon steel sheet to be processed can be determined, clarifying the sequential position of the current silicon steel sheet to be processed in the sheet-by-sheet generation process. Then, based on the sheet number and the silicon steel sheet thickness parameters, the corresponding radius increment is determined, allowing the sheet thickness variation relationship to be introduced into the target radius generation process. Finally, the initial radius is incrementally increased based on the radius increment to obtain the target radius corresponding to the current silicon steel sheet to be processed. This allows for the generation of radius parameters corresponding to each silicon steel sheet to be processed in sheet-by-sheet order, giving the target radius generation process a clear progressive relationship and calculation basis. This improves the accuracy of target radius determination, the orderliness of sheet-by-sheet generation, and the adaptability of subsequent contour solving and processing control.

[0038] Preferably, the step of selecting the corresponding boundary equation and the material circle equation to find the intersection based on the radius segment interval of the target radius corresponding to the current silicon steel sheet to be processed, to obtain the two target intersection points corresponding to the current silicon steel sheet to be processed, includes:

[0039] When the target radius is located within the first radius segment interval, the oblique line equation and the parallel line equation are selected, and the intersection is obtained based on the material circle equation, the oblique line equation and the parallel line equation to obtain the two target intersection points corresponding to the silicon steel sheet to be processed.

[0040] When the target radius is located within the second radius segment interval, the small circle equation and the parallel line equation are selected, and the intersection is obtained based on the material circle equation, the small circle equation, and the parallel line equation to obtain the two target intersection points corresponding to the silicon steel sheet to be processed.

[0041] When the target radius is located within the third radius segment interval, the outer circle equation and the parallel line equation are selected, and the intersection of the material circle equation, the outer circle equation, and the parallel line equation is obtained to obtain the two target intersection points corresponding to the silicon steel sheet to be processed.

[0042] By adopting the above technical solution, when the target radius is located within the first radius segment interval, the equations of the oblique line and the parallel line are selected, and their intersection is found based on the material circle equation, the oblique line equation, and the parallel line equation. When the target radius is located within the second radius segment interval, the equations of the small circle and the parallel line are selected, and their intersection is found based on the material circle equation, the small circle equation, and the parallel line equation. When the target radius is located within the third radius segment interval, the equations of the outer circle and the parallel line are selected, and their intersection is found based on the material circle equation, the outer circle equation, and the parallel line equation. This allows for the automatic matching of boundary solution methods adapted to the current contour stage based on the different radius segment intervals where the target radius of the silicon steel sheet to be processed is located. This ensures that the target intersection point acquisition process under different contour stages has a clear segmental correspondence, avoiding the intersection point matching deviation caused by using the same set of boundary equations to solve different contour stages. This improves the accuracy of target intersection point solution, the effectiveness of contour segment adaptation, and the stability of lung-shaped silicon steel sheet processing control.

[0043] Preferably, the step of determining the target chord length based on the two target intersection points, and determining the target arc length based on the target chord length and the target radius, includes:

[0044] Obtain the first coordinate information and the second coordinate information corresponding to the intersection points of the two targets, respectively;

[0045] Based on the first coordinate information and the second coordinate information, determine the target chord length between the two target intersection points;

[0046] The target arc length corresponding to the silicon steel sheet to be processed is determined based on the target chord length and the target radius.

[0047] By adopting the above technical solution, the first coordinate information and the second coordinate information corresponding to the two target intersection points are obtained respectively, which can provide a clear coordinate basis for calculating the length of the contour segment corresponding to the silicon steel sheet to be processed. Then, the target chord length between the two target intersection points is determined according to the first coordinate information and the second coordinate information, which can transform the spatial positional relationship between the target intersection points into a quantifiable straight-line distance parameter. Furthermore, the target arc length corresponding to the silicon steel sheet to be processed is determined according to the target chord length and the target radius, which can further transform the geometric relationship corresponding to the target chord length into an arc length parameter corresponding to the silicon steel sheet to be processed. This allows the contour boundary information to be directly associated with the length calculation process, thereby improving the accuracy of the target arc length determination, the reliability of the processing length generation, and the adaptability of subsequent processing control.

[0048] Preferably, the step of determining the target arc length as the processing length corresponding to the current silicon steel sheet to be processed, and controlling the processing equipment to process the current silicon steel sheet to be processed according to the processing length, includes:

[0049] The target arc length is determined as the processing length corresponding to the silicon steel sheet to be processed;

[0050] The feeding mechanism is controlled to perform feeding according to the processing length, so that the silicon steel sheet to be processed reaches the preset processing position.

[0051] When the silicon steel sheet to be processed reaches the preset processing position, the punching mechanism is controlled to perform punching processing on the silicon steel sheet to be processed.

[0052] After completing the punching process, the bevel cutting mechanism is controlled to perform bevel cutting on the silicon steel sheet to be processed.

[0053] After completing the oblique cut, the right-angle cutting mechanism is controlled to perform a right-angle cut on the silicon steel sheet to be processed.

[0054] By adopting the above technical solution, the target arc length is first determined as the processing length corresponding to the silicon steel sheet to be processed. This allows the arc length result obtained based on contour solving to be directly converted into a length parameter that can be used for processing control. Then, the feeding mechanism is controlled to perform feeding according to the processing length, so that the silicon steel sheet to be processed reaches the preset processing position. This enables the silicon steel sheet to be processed to be positioned and transported according to the corresponding processing length. When the silicon steel sheet to be processed reaches the preset processing position, the punching mechanism is controlled to perform punching processing on the silicon steel sheet to be processed, enabling the punching action to be performed. Matching the current position of the silicon steel sheet to be processed, after completing the punching process, the bevel cutting mechanism is controlled to perform bevel cutting on the current silicon steel sheet to be processed, and after completing the bevel cutting, the right angle cutting mechanism is controlled to perform right angle cutting on the current silicon steel sheet to be processed. This allows the subsequent forming process of the current silicon steel sheet to be processed to be completed according to the predetermined processing sequence, so that the processing length information is directly integrated into the feeding, punching, bevel cutting and right angle cutting processes, thereby improving the continuity of the processing control of the current silicon steel sheet to be processed, the accuracy of the processing position matching, and the consistency of the forming of the lung-shaped silicon steel sheet.

[0058] The boundary equation construction module is used to construct the inner circle equation, outer circle equation, small circle equation, oblique line equation, and parallel line equation based on the basic parameters.

[0059] The radius segmentation determination module is used to solve the intersection point based on the inner circle equation, the outer circle equation, the small circle equation, the oblique line equation, and the parallel line equation to obtain the radius information corresponding to multiple segmentation reference points, and to determine multiple radius segmentation intervals based on the radius information corresponding to the multiple segmentation reference points.

[0060] The target radius generation module is used to generate the target radius corresponding to each silicon steel sheet to be processed, starting from a preset reference radius, based on the silicon steel sheet thickness parameter in the basic parameters.

[0061] The target intersection point solution module is used to select the corresponding boundary equation and the material circle equation to find the intersection based on the radius segment interval where the target radius of the current silicon steel sheet to be processed is located, so as to obtain the two target intersection points corresponding to the current silicon steel sheet to be processed.

[0063] The processing execution control module is used to determine the target arc length as the processing length corresponding to the current silicon steel sheet to be processed, and to control the processing equipment to process the current silicon steel sheet according to the processing length.

[0064] By adopting the above technical solution, the basic parameters corresponding to the lobe-shaped silicon steel sheet are first obtained, and based on this, inner circle equations, outer circle equations, small circle equations, oblique line equations, and parallel line equations are constructed. This transforms the contour boundary relationship of the lobe-shaped silicon steel sheet into a calculable equation relationship. Then, the radius information corresponding to multiple segmented reference points is obtained by solving the intersection points, and multiple radius segment intervals are determined based on the radius information corresponding to multiple segmented reference points. This provides a clear segmentation basis for radius changes under different contour stages, thereby avoiding reliance on manual trial calculations for each sheet during the overall verification process and improving the accuracy of contour segmentation solutions. Furthermore, based on the silicon steel sheet thickness parameters, the target radius corresponding to each silicon steel sheet to be processed is generated one by one, starting from a preset reference radius, and the corresponding radius segment interval is selected based on the radius segment interval where the target radius is located. The boundary equations are intersected with the material circle equations to obtain two target intersection points corresponding to the current silicon steel sheet to be processed. This allows the geometric boundaries corresponding to different sheet numbers to automatically match the corresponding solution paths, thereby improving the adaptability of the contour solution for each silicon steel sheet to be processed. Then, the target chord length is determined based on the two target intersection points, and the target arc length is determined based on the target chord length and the target radius. This directly transforms the contour boundary relationship into a processing length that can be used for processing control, thereby improving the efficiency and accuracy of processing length determination. Finally, the target arc length is determined as the processing length corresponding to the current silicon steel sheet to be processed, and the processing equipment is controlled to process the current silicon steel sheet according to the processing length. This allows the parameter solution results to directly affect the actual processing process, thereby improving the automation level and processing consistency of the lung-shaped silicon steel sheet processing process.

[0067] In summary, this application includes at least one of the following beneficial technical effects:

[0068] First, the basic parameters corresponding to the lobe-shaped silicon steel sheet are obtained, and based on these, inner circle equations, outer circle equations, small circle equations, oblique line equations, and parallel line equations are constructed. This transforms the contour boundary relationship of the lobe-shaped silicon steel sheet into a calculable equation relationship. Then, the radius information corresponding to multiple segmented reference points is obtained by solving through intersection points. Based on the radius information corresponding to multiple segmented reference points, multiple radius segment intervals are determined, providing a clear segmentation basis for radius changes under different contour stages. This avoids relying on manual trial calculations for each sheet during the overall verification process, improving the accuracy of contour segmentation solutions. Furthermore, based on the silicon steel sheet thickness parameters, the target radius corresponding to each silicon steel sheet to be processed is generated one by one, starting from a preset reference radius. Based on the radius segment interval where the target radius is located, the corresponding boundary equation and material... The intersection of the material circle equations yields two target intersection points corresponding to the current silicon steel sheet to be processed. This allows the geometric boundaries corresponding to different sheet numbers to automatically match the corresponding solution paths, thereby improving the adaptability of the contour solution for each silicon steel sheet to be processed. Then, the target chord length is determined based on the two target intersection points, and the target arc length is determined based on the target chord length and the target radius. This directly transforms the contour boundary relationship into a processing length that can be used for processing control, thereby improving the efficiency and accuracy of processing length determination. Finally, the target arc length is determined as the processing length corresponding to the current silicon steel sheet to be processed, and the processing equipment is controlled to process the current silicon steel sheet according to the processing length. This allows the parameter solution results to directly affect the actual processing process, thereby improving the automation level and processing consistency of the lung-shaped silicon steel sheet processing process.

[0070] Figure 2 This is a schematic diagram of an automated control device for cutting irregularly shaped sheets according to one embodiment of this application. Detailed Implementation

[0071] The present application will be further described in detail below with reference to the accompanying drawings.

[0072] In one embodiment, such as Figure 1 As shown, this application discloses an automated control method for cutting irregularly shaped sheets, which specifically includes the following steps:

[0073] S10: Obtain the basic parameters corresponding to the lung-shaped silicon steel sheet.

[0074] In this embodiment, the basic parameters refer to the input parameters used to characterize the boundary relationship of the lung-shaped silicon steel sheet and the sheet thickness relationship. The lung-shaped silicon steel sheet refers to a silicon steel sheet whose outline is defined by an inner circle, an outer circle, a small circle, an oblique line, and a parallel line.

[0075] Specifically, when obtaining the basic parameters corresponding to the lobe-shaped silicon steel sheet, a parameter input area is established through a human-computer interaction interface. Within this area, input positions are set for the inner circle center coordinates, inner circle radius, outer circle center coordinates, outer circle radius, small circle center coordinates, small circle radius, oblique line angle, parallel line parameter, and silicon steel sheet thickness parameter. The parameters entered at each input position are then read and extracted according to their category. Specifically, the inner circle center coordinates and inner circle radius are combined to obtain the inner circle parameter; the outer circle center coordinates and outer circle radius are combined to obtain the outer circle parameter; the small circle center coordinates and small circle radius are combined to obtain the small circle parameter; the oblique line angle is read to obtain the oblique line parameter; the parallel line parameter is read to obtain the parallel line parameter; and the silicon steel sheet thickness parameter is read to obtain the thickness parameter. Finally, the inner circle parameter, outer circle parameter, small circle parameter, oblique line parameter, parallel line parameter, and thickness parameter are summarized to obtain the basic parameters corresponding to the lobe-shaped silicon steel sheet.

[0076] S20: Construct equations for the inner circle, outer circle, small circle, oblique line, and parallel line based on the basic parameters.

[0077] In this embodiment, the inner circle equation refers to the equation expression corresponding to the inner circle established based on the coordinates of the inner circle's center and the inner circle's radius; the outer circle equation refers to the equation expression corresponding to the outer circle established based on the coordinates of the outer circle's center and the outer circle's radius; the small circle equation refers to the equation expression corresponding to the small circle established based on the coordinates of the small circle's center and the small circle's radius; the oblique line equation refers to the equation expression corresponding to the oblique line established based on the oblique line parameters; and the parallel line equation refers to the equation expression corresponding to the parallel line established based on the parallel line parameters.

[0078] Specifically, when constructing the equations for the inner circle, outer circle, smaller circle, oblique line, and parallel line based on the basic parameters, the coordinates of the inner circle's center and the inner circle's radius are first extracted from the basic parameters. The coordinates of the inner circle's center are used as the center position parameter of the inner circle, and the inner circle's radius is used as the distance constraint parameter of the inner circle. Based on the relationship between the circle's center position and radius, the corresponding equation expression for the inner circle is established, thus obtaining the inner circle equation. Then, the coordinates of the outer circle's center and the outer circle's radius are extracted from the basic parameters. The coordinates of the outer circle's center are used as the center position parameter of the outer circle, and the outer circle's radius is used as the distance constraint parameter of the outer circle. Based on the relationship between the circle's center position and radius, the corresponding equation expression for the outer circle is established. The equation of the outer circle is obtained by first extracting the center coordinates and radius of the small circle from the basic parameters. The center coordinates of the small circle are used as the center position parameter of the small circle, and the radius of the small circle is used as the distance constraint parameter of the small circle. Based on the relationship between the center position and the radius of the circle, the equation expression of the small circle is established, and the equation of the small circle is obtained. Then, the oblique line parameter is extracted from the basic parameters, and the equation expression of the oblique line is established based on the slope and position relationship represented by the oblique line parameter, and the equation of the oblique line is obtained. Finally, the parallel line parameter is extracted from the basic parameters, and the equation expression of the parallel line is established based on the position relationship of the parallel line represented by the parallel line parameter, and the equation of the parallel line is obtained.

[0079] S30: Solve the intersection point based on the equations of the inner circle, outer circle, small circle, oblique line, and parallel line to obtain the radius information corresponding to multiple segmented reference points, and determine multiple radius segment intervals based on the radius information corresponding to multiple segmented reference points.

[0080] In this embodiment, the segmented reference point refers to the intersection point used to divide the contour change boundary of the lung-shaped silicon steel sheet, obtained by combining the inner circle equation, outer circle equation, small circle equation, oblique line equation and parallel line equation in pairs. The radius information refers to the distance parameter formed by pointing from the origin of the coordinate system to each segmented reference point. The radius segmentation interval refers to multiple radius ranges formed by dividing the radius information corresponding to multiple segmented reference points according to the size rule.

[0081] Specifically, based on the equations of the inner circle, outer circle, small circle, oblique line, and parallel line, the intersection points are solved to obtain the radius information corresponding to multiple segmented reference points. When determining multiple radius segment intervals based on this radius information, the inner circle equation and the oblique line equation are first solved simultaneously to obtain the coordinates of the intersection point between the inner circle and the oblique line, and this intersection point coordinates are determined as the first segmented reference point. Then, the small circle equation and the oblique line equation are solved simultaneously to obtain the coordinates of the intersection point between the small circle and the oblique line, and this intersection point coordinates are determined as the second segmented reference point. Finally, the small circle equation and the outer circle equation are solved simultaneously to obtain the coordinates of the intersection point between the small circle and the outer circle, and this intersection point coordinates are determined as the second segmented reference point. The coordinates are determined as the third segment reference point. Then, the equations of the outer circle and the parallel line are combined to obtain the coordinates of the intersection point of the outer circle and the parallel line. The coordinates of the intersection point are determined as the fourth segment reference point. Then, the coordinate values ​​of the first, second, third, and fourth segment reference points are read respectively. The corresponding radius values ​​are calculated according to the distance relationship between the origin and each segment reference point to obtain the radius information corresponding to multiple segment reference points. Finally, the radius information corresponding to multiple segment reference points is sorted according to the size pattern, and the adjacent radius values ​​are used as the interval boundaries to divide multiple radius ranges, resulting in multiple radius segment intervals.

[0082] S40: Based on the silicon steel sheet thickness parameter in the basic parameters, generate the target radius corresponding to each silicon steel sheet to be processed, starting from the preset reference radius.

[0083] In this embodiment, the preset reference radius refers to the initial radius parameter used as the starting value for radius increment, and the target radius refers to the radius parameter corresponding to each silicon steel sheet to be processed during the sheet-by-sheet generation process.

[0084] Specifically, based on the silicon steel sheet thickness parameter in the basic parameters, when generating the target radius corresponding to each silicon steel sheet to be processed, starting from the preset reference radius, the silicon steel sheet thickness parameter is first extracted from the basic parameters, and the preset reference radius is determined as the starting point for radius generation. Then, each silicon steel sheet to be processed is assigned a corresponding sheet number in sequence according to the processing order. Then, each sheet number is multiplied by the silicon steel sheet thickness parameter to obtain the radius increment corresponding to each silicon steel sheet to be processed. Subsequently, each radius increment is superimposed with the preset reference radius to obtain the target radius corresponding to each silicon steel sheet to be processed. Among them, the radius increment corresponding to the silicon steel sheet to be processed is larger as the sheet number is later. This forms multiple target radii arranged in ascending order of sheet number. The multiple target radii are associated and stored according to the correspondence with each silicon steel sheet to be processed to obtain the target radius corresponding to each silicon steel sheet to be processed.

[0085] S50: Based on the radius segmentation interval of the target radius corresponding to the current silicon steel sheet to be processed, select the corresponding boundary equation and the material circle equation to find the intersection, and obtain the two target intersection points corresponding to the current silicon steel sheet to be processed.

[0086] In this embodiment, the current silicon steel sheet to be processed refers to the silicon steel sheet that is currently in the solution position according to the sheet number among multiple silicon steel sheets to be processed. The boundary equation refers to the equation selected from the inner circle equation, outer circle equation, small circle equation, oblique line equation, and parallel line equation based on the radius segment interval where the target radius is located.

[0158] Specifically, when determining the target arc length as the processing length corresponding to the current silicon steel sheet to be processed, firstly, the value of the target arc length corresponding to the current silicon steel sheet to be processed is read and recorded as Ln. Then, a length mapping relationship is established between the target arc length and the current silicon steel sheet to be processed, so that the target arc length is consistent with the processing dimension corresponding to the current silicon steel sheet in terms of length attribute. Subsequently, the value of the target arc length is directly assigned to the processing length parameter corresponding to the current silicon steel sheet to be processed, according to...

[0161] Specifically, the feeding mechanism is controlled to feed the silicon steel sheet according to the processing length. When the silicon steel sheet reaches the preset processing position, the processing length corresponding to the current silicon steel sheet is first read and recorded as ln. Then, the current feeding start position corresponding to the feeding mechanism is read and recorded as x0.

A preset processing position is determined, where xt represents the preset processing position, x0 represents the current feeding start position, and ln represents the processing length corresponding to the current silicon steel sheet to be processed. Then, a feeding displacement control amount is generated based on the position difference between the preset processing position and the current feeding start position, and the feeding displacement control amount is sent to the feeding mechanism. The feeding mechanism drives the current silicon steel sheet to be processed to move along the feeding direction according to the feeding displacement control amount until the actual feeding position corresponding to the current silicon steel sheet to be processed is consistent with the preset processing position.

If the actual feeding position and the preset processing position meet the preset position consistency condition, a punching trigger signal corresponding to the silicon steel sheet is generated and sent to the punching mechanism to put it into the punching action state. Then, the punching mechanism is controlled to perform downward punching on the silicon steel sheet according to the preset punching stroke to form the target hole corresponding to the silicon steel sheet. After the target hole is formed, the punching mechanism is controlled to perform a reset action, thereby completing the punching process of the silicon steel sheet.

If the completion status meets the preset completion conditions, a bevel cutting trigger signal is generated. This signal is then sent to the bevel cutting mechanism to put it into the bevel cutting preparation state. Subsequently, the bevel cutting mechanism is controlled to perform bevel cutting on the edge of the silicon steel sheet to be processed according to a preset bevel trajectory, forming the beveled edge corresponding to the silicon steel sheet. The completion status corresponding to the punching process is denoted as sp, and the bevel cutting trigger signal is denoted as ua. The process is then performed according to the following:

[0168] Determine the oblique cutting trigger signal, where sp=1 indicates that the punching process is completed and sp=0 indicates that the punching process is not completed. After the oblique cutting mechanism completes the oblique cutting of the current silicon steel sheet to be processed, the corresponding oblique cutting completion status is output, thereby completing the oblique cutting of the current silicon steel sheet to be processed.

The right-angle cutting trigger signal is then sent to the right-angle cutting mechanism to put it into the right-angle cutting preparation state. Subsequently, the right-angle cutting mechanism is controlled to perform cutting along the cutting direction intersecting the feeding direction of the current silicon steel sheet to be processed, forming the right-angle cut edge corresponding to the current silicon steel sheet to be processed. The completion status corresponding to the bevel cutting is denoted as sa, and the right-angle cutting trigger signal is denoted as uv. The process is then carried out according to...

[0172] The right-angle cutting trigger signal is determined, where sa=1 indicates that the oblique cutting is completed and sa=0 indicates that the oblique cutting is not completed. After the right-angle cutting mechanism completes the cutting process of the current silicon steel sheet to be processed, the corresponding right-angle cutting completion status is output, thereby completing the right-angle cutting of the current silicon steel sheet to be processed.
