[0034] Blanking is a key metal processing technology. When blanking, metal sheets or coils need to be cut into parts of corresponding shapes according to specific blanking dies. In the production and manufacturing process of automobiles, special-shaped materials such as side panels and four-door inner panels are produced by stamping and blanking. However, in the current blanking method of special-shaped materials, each model of special-shaped material requires a customized blanking die to achieve precise cutting. For example, the side panels of model A need to be Figure 1 The blanking die shown is used for blanking, and the side outer panel of model B needs to be blanked using Figure 2 The blanking die shown is used for blanking; when there are many types of vehicles, the existing method of blanking special-shaped materials will lead to higher production costs.

[0035] In view of this, the embodiments of the present application provide a method, apparatus, computer-readable storage medium and terminal device for blanking special-shaped materials to solve the problem of high production and manufacturing costs of the method for blanking special-shaped materials in the prior art.

[0036] It should be noted that the execution subject of the method of the present application is a terminal device, specifically, it can be a common computing device such as a desktop computer, a notebook, a handheld computer, or other computing devices.

[0037] See also Figure 3 In the embodiment of the present application, an embodiment of a method for blanking a special-shaped material may include:

[0038] Step S301, obtaining a target blanking line diagram corresponding to a target special-shaped material.

[0039] In the embodiment of the present application, when it is necessary to blank the special-shaped material, the corresponding blanking line diagram can be determined according to the special-shaped material to be blanked. For the convenience of description, in the embodiment of the present application, the special-shaped material to be blanked can be referred to as the target special-shaped material, and the blanking line diagram of the special-shaped material to be blanked can be referred to as the target blanking line diagram.

[0040] Here, the target blanking line diagram can be determined according to the size, shape and other parameters of the target special-shaped material. The specific determination method can refer to any method for determining the blanking line diagram in the prior art, and the present application does not limit this.

[0041] Step S302: Match the target blanking line diagram with each candidate blanking line diagram in a preset blanking line diagram database.

[0042] In order to save the production cost of the blanking die, in the embodiment of the present application, the blanking die required for the target special-shaped material can be matched with the blanking die of the existing vehicle model to determine whether there is a possibility of reusing the existing blanking die; if there is a reusable blanking die, the reusable blanking die can be directly used for blanking; accordingly, the cost of blanking die production and design can be reduced, and the availability and utilization rate of the blanking die can be improved.

[0043] In the embodiment of the present application, the blanking line diagrams of various existing models can be collected and sorted, and based on the blanking line diagrams of various existing models, a blanking line diagram database can be constructed. Afterwards, the target blanking line diagram can be matched with each blanking line diagram in the blanking line diagram database.

[0044] In a specific implementation of the embodiment of the present application, each blanking line diagram in the blanking line diagram database can be classified according to the type of special-shaped materials to improve the efficiency of subsequent matching; wherein the type of special-shaped materials can be one of vehicle parts such as a vehicle side outer panel, a vehicle front door inner panel, a vehicle rear door inner panel, etc.; for example, refer to Figure 4 , the blanking line diagrams corresponding to the rear door inner panel can be divided into a category, which can include the blanking line diagram of the rear door inner panel of model A, the blanking line diagram of the rear door inner panel of model B, the blanking line diagram of the rear door inner panel of model C, the blanking line diagram of the rear door inner panel of model D, the blanking line diagram of the rear door inner panel of model E, the blanking line diagram of the rear door inner panel of model F, and the blanking line diagram of the rear door inner panel of model G.

[0045] In an embodiment of the present application, in order to improve the matching efficiency, before matching the target blanking line diagram with the blanking line diagram in the blanking line diagram database, each blanking line diagram in the blanking line diagram database may be preliminarily screened to determine the blanking line diagram in the blanking line diagram database that is less different from the target blanking line diagram, and exclude the blanking line diagram in the blanking line diagram database that is significantly different from the target blanking line diagram; thereafter, the target blanking line diagram is accurately matched with the blanking line diagram preliminarily screened in the blanking line diagram database to more efficiently determine a reusable blanking die. Here, the blanking line diagram preliminarily screened in the blanking line diagram database may be referred to as a candidate blanking line diagram.

[0046] Specifically, the target special-shaped material can be matched with various special-shaped materials in a preset vehicle model project database; wherein the vehicle model project database may include the size information of the special-shaped materials of various existing vehicle models, and the size information of the special-shaped material may include but is not limited to the total length, width, thickness, thickness, angle, hole position, hole diameter and other dimensional parameters of the special-shaped material.

[0047] Here, the size difference between the target special-shaped material and the special-shaped material in the vehicle model project database can be calculated. If the difference is less than or equal to the preset special-shaped material difference threshold, it can be considered that the target special-shaped material matches the special-shaped material in the vehicle model project database successfully; otherwise, it can be considered that the target special-shaped material matches the special-shaped material in the vehicle model project database unsuccessfully. The special-shaped material difference threshold can be specifically set according to actual needs, and the embodiment of the present application does not limit this.

[0048] If the target special-shaped material successfully matches at least one special-shaped material in the vehicle model database, the vehicle model corresponding to the successfully matched special-shaped material can be determined as the candidate vehicle model. If the target special-shaped material fails to match all the special-shaped materials in the vehicle model database, it can be considered that there is a significant difference between the target special-shaped material and the special-shaped materials of the existing vehicle models, and it is difficult to use the existing blanking die for blanking, and there is no need to continue the subsequent process.

[0049] After the candidate model is determined, the candidate blanking line diagram can be screened out in the blanking line diagram database according to the candidate model and the type of the target special-shaped material. Specifically, the blanking line diagram in the blanking line diagram database that belongs to the candidate model and has the same type as the target special-shaped material can be used as the candidate blanking line diagram.

[0050] For example, the type of the target special-shaped material is the inner panel of the front door of the vehicle. In the preliminary screening process, the target special-shaped material successfully matches the special-shaped materials of model A, model B and model C, then model A, model B and model C can be determined as candidate models; in the blanking line diagram database, the blanking line diagram of the vehicle side outer panel of model A is the blanking line diagram. Figure 1 The blanking line diagram of the side panel of the vehicle model B is the blanking line Figure 2 The blanking line diagram of the side panel of the vehicle model C is the blanking line Figure 3 , then the blanking line can be Figure 1 , Blanking Line Figure 2 and blanking lines Figure 3 Determined as a candidate blanking line diagram, such as Figure 5 shown.

[0051] Afterwards, the target blanking line diagram may be matched with each candidate blanking line diagram in the blanking line diagram database, and whether the match is successful may be determined based on a preset difference threshold.

[0052] Specifically, the target blanking line diagram and the candidate blanking line diagram may be aligned according to a reference datum to obtain an aligned target blanking line diagram and an aligned candidate blanking line diagram; wherein the reference datum may include a reference datum point and a reference scale.

[0053] In the embodiment of the present application, the reference reference point and the reference scale can be set specifically and situationally according to actual needs, and the present application does not limit this. For example, the reference reference point can be set to the bottom point of the A-pillar, and the reference scale can be set to 400×400.

[0054] Afterwards, the difference between the aligned target blanking line diagram and the aligned candidate blanking line diagram can be calculated; specifically, the roll width difference between the aligned target blanking line diagram and the aligned candidate blanking line diagram can be calculated, and the blanking line shear length difference between the aligned target blanking line diagram and the aligned candidate blanking line diagram can also be calculated.

[0055] If the difference between the target blanking line diagram and the candidate blanking line diagram is greater than the preset difference threshold, it can be considered that there is a large difference between the target blanking line diagram and the candidate blanking line diagram, and at this time, it can be determined that the target blanking line diagram and the candidate blanking line diagram have failed to match. The difference threshold may include a roll width difference threshold and a blanking line shear length difference threshold; specifically, if the roll width difference between the target blanking line diagram and the candidate blanking line diagram is greater than the preset roll width difference threshold, or the blanking line shear length difference between the target blanking line diagram and the candidate blanking line diagram is greater than the preset blanking line shear length difference threshold, it can be determined that the target blanking line diagram and the candidate blanking line diagram have failed to match.

[0056] If the difference between the target blanking line diagram and the candidate blanking line diagram is less than or equal to the difference threshold, it can be considered that the difference between the target blanking line diagram and the candidate blanking line diagram is small, and at this time, it can be determined that the target blanking line diagram and the candidate blanking line diagram are successfully matched. Specifically, if the roll width difference between the target blanking line diagram and the candidate blanking line diagram is less than or equal to the roll width difference threshold, and the blanking line shear length difference between the target blanking line diagram and the candidate blanking line diagram is less than or equal to the blanking line shear length difference threshold, it can be determined that the target blanking line diagram and the candidate blanking line diagram are successfully matched.

[0057] Here, the difference threshold can be set specifically and situationally according to actual needs, and this application does not limit this. For example, the roll width difference threshold can be set to 30 mm, and the blanking line shear length difference threshold can be set to 20 mm.

[0058] For example, see Figure 6 , the target blanking line diagram can be compared with the candidate blanking line diagram according to the preset reference benchmark Figure 1 Align and obtain the aligned target blanking line diagram and candidate blanking line diagram Figure 1; For the target blanking line diagram after alignment, the length of the vertical line segment passing through the reference reference point in the target blanking line diagram (i.e., the roll width) can be measured to be 1750 mm, and the shear length of the blanking line in the target blanking line diagram can be measured to be 319 mm; for the candidate blanking line after alignment Figure 1 , the length of the vertical line segment passing through the reference point in candidate blanking line 1 (i.e., the roll width) can be measured to be 1720 mm, and the shear length of the blanking line in candidate blanking line 1 can also be measured to be 319 mm; therefore, the aligned target blanking line diagram and the aligned candidate blanking line diagram can be calculated. Figure 1 The roll width difference is 30 mm, that is, the roll width difference between the aligned target blanking line diagram and the aligned candidate blanking line diagram is 30 mm, which is equal to the preset roll width difference threshold of 30 mm, and the blanking line shear length between the aligned target blanking line diagram and the aligned candidate blanking line diagram is the same, that is, the blanking line shear length difference between the aligned target blanking line diagram and the aligned candidate blanking line diagram is 0 mm, which is less than the preset blanking line shear length threshold of 20 mm; therefore, it can be determined that the target blanking line diagram and the candidate blanking line diagram are aligned. Figure 1 The match was successful.

[0059] In a specific implementation, the target blanking line diagram and the candidate blanking line diagram can be unified into a reference scale; then, the reference reference point of the target blanking line diagram can be aligned with the reference reference point of the candidate blanking line diagram to obtain an overlapping comparison diagram of the target blanking line diagram and the candidate blanking line diagram, such as Figure 7 As shown, according to the above process, the candidate blanks can be obtained Figure 1 Overlap comparison diagram with target blanking line diagram, candidate blanking Figure 2 Overlap comparison diagram with target blanking line diagram, candidate blanking Figure 3 Overlap comparison diagram with the target blanking line diagram. Afterwards, the difference between the target blanking line diagram and the candidate blanking line diagram can be calculated more intuitively and clearly based on the overlap comparison diagram.

[0060] Step S303: If the target blanking line graph successfully matches at least one candidate blanking line graph, determine the target blanking die based on the successfully matched candidate blanking line graph.

[0061] If the target blanking line graph successfully matches at least one candidate blanking line graph, it indicates that there is at least one blanking die of an existing vehicle model that can be reused.

[0062] In an embodiment of the present application, if the target blanking line diagram successfully matches at least one candidate blanking line diagram, the target blanking die can be determined based on the successfully matched candidate blanking line diagram. Specifically, the target matching blanking line diagram can be determined from the successfully matched candidate blanking line diagrams, and then the target blanking die can be determined based on the target matching blanking line diagram.

[0063] Specifically, if the target blanking line diagram successfully matches only one candidate blanking line diagram, the successfully matched candidate blanking line diagram can be determined as the target matching blanking line diagram, and the blanking die corresponding to the target matching blanking line diagram can be directly determined as the target blanking die.

[0064] If the target blanking line diagram successfully matches with two or more candidate blanking line diagrams, the target matching blanking line diagram can be determined from the successfully matched candidate blanking line diagrams, and the blanking die corresponding to the target matching blanking line diagram can be directly determined as the target blanking die. Specifically, the candidate blanking line diagram that is most similar to the target matching blanking line diagram can be selected from the successfully matched candidate blanking line diagrams as the target matching blanking line diagram.

[0065] For example, the target blanking line graph is only related to the candidate blanking line Figure 1 If the match is successful, the candidate blanking line can be directly Figure 1 Determine the target matching blanking line diagram and assign the candidate blanking Figure 1 The corresponding blanking die is determined as the target blanking die.

[0066] For example, the target blanking line diagram and the candidate blanking line diagram Figure 1 , Candidate blanking line Figure 2 , Candidate blanking line Figure 3 All matched successfully, the target blanking line diagram and the candidate blanking line Figure 1 The difference between them is difference 1, the target blanking line diagram and the candidate blanking line Figure 2 The difference between them is difference 2, the target blanking line diagram and the candidate blanking line diagram Figure 3 The difference between them is difference 3; if difference 2> difference 1> difference 3, that is, difference 3 is the smallest, then it can be considered that the target blanking line diagram is the same as the candidate blanking line diagram. Figure 3 is most similar, so the candidate blanking line can be Figure 3 Determine the target matching blanking line diagram and assign the candidate blanking line Figure 3 The corresponding blanking die is determined as the target blanking die.

[0067] In a specific implementation method of an embodiment of the present application, in order to ensure the blanking effect, after determining the target matching blanking line diagram, the target matching blanking line diagram can also be subjected to precise computer-aided engineering (CAE) synchronous engineering analysis to obtain the computer-aided engineering synchronous engineering analysis result of the target matching blanking line diagram. If the computer-aided engineering synchronous engineering analysis result of the target matching blanking line diagram meets the preset sharing conditions, it can be determined that the blanking die corresponding to the target matching blanking line diagram can be reused. At this time, the blanking die corresponding to the target matching blanking line diagram can be determined as the target blanking die; if the computer-aided engineering synchronous engineering analysis result of the target matching blanking line diagram does not meet the sharing conditions, it can be determined that the blanking die corresponding to the target matching blanking line diagram cannot be reused; accordingly, the blanking effect can be further ensured. Here, specifically, the common CAE software in the prior art can be used to perform computer-aided engineering synchronous engineering analysis on the target blanking line diagram, and the common condition can be that the size difference between the target matching blanking line diagram and the target blanking line diagram is less than a preset size difference threshold. The size difference threshold can be set according to actual conditions, and this application does not limit this.

[0068] Step S304: blanking the target special-shaped material based on the target blanking die.

[0069] In a specific implementation of the embodiment of the present application, the target blanking die can be directly used to blank the target special-shaped material.

[0070] In another specific implementation of the embodiment of the present application, the target blanking die can be adjusted based on the target blanking line diagram to obtain the adjusted target blanking die; accordingly, the target blanking die can be better adapted to the size and shape of the target special-shaped material. Among them, the mold adjustment method can refer to the common process processing method in the prior art, and the present application does not limit this; for example, the target blanking die can be manually polished to obtain the adjusted target blanking die. For another example, the target blanking die can be subjected to mechanical processing such as milling, turning, and grinding to obtain the adjusted target blanking die.

[0071] In summary, the embodiment of the present application obtains a target blanking line diagram corresponding to a target special-shaped material; matches the target blanking line diagram with each candidate blanking line diagram in a preset blanking line diagram database; wherein the blanking line diagram database includes blanking line diagrams of each existing vehicle model; if the target blanking line diagram successfully matches at least one of the candidate blanking line diagrams, a target blanking die is determined based on the successfully matched candidate blanking line diagram; and the target special-shaped material is blanked based on the target blanking die. In the embodiment of the present application, a blanking line diagram database including blanking line diagrams of each existing vehicle model can be constructed, and a suitable blanking line diagram can be matched in the blanking line diagram database, and the corresponding existing blanking die can be determined based on the matched blanking line diagram, thereby eliminating the need to redesign and produce the blanking die, greatly saving production costs.
