Description

Technical Field

[0001] The present invention relates to the technical field of tire automated design, and in particular, to a method, device, and program product for automatically expanding and locally saving tire product drawings based on contour replacement. Background Art

[0002] During the development of tire product drawings, it is generally divided into two design stages: the first stage is the design and development of contour drawings, and the second stage is the design and development of tread and sidewall drawings. In conventional designs, generally, the project leader first designs the contour drawings of all specifications for tire products with the same design rules. After all the contour drawings pass simulation, optimization, and review, serial tread and sidewall designs and expansions are carried out.

[0003] Since the contour drawing is the first stage of the design, when performing serial expansions on subsequent tread and sidewall drawings, it is necessary to re-import the curves, positioning points, positioning axes, etc. of the contour drawing distribution as external inputs, so as to achieve top-down driven collaborative design of the contour drawing. In this process, if manual replacement is used by importing each contour drawing one by one and publishing elements one by one, the efficiency is low and it is easy to cause human errors, resulting in errors in the assembly drawings of tire products, thus causing waste of time and cost in mold processing; at the same time, the import of each contour drawing also affects the update and saving efficiency of tread and sidewall drawings during serial expansion of multiple specifications, and it is easy to cause cumbersome and chaotic saving of design drawings. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a method for automatically expanding and locally saving tire product drawings based on contour replacement. This method automatically calls contour drawings one by one from a specified path, replaces the current contour release elements with the release elements of the newly called replacement contour, and drives the automatic update of the tread drawing and the sidewall drawing. While each product configuration is updated, the local coding rules are used to code and locally save the necessary parts and drawings. Since the serial multi-contour drawings are automatically called by the program and the upstream and downstream design elements are replaced, the drawing expansion efficiency is greatly improved, and the local saving of drawing files is achieved. It is used for the serial expansion of tread and sidewall drawings under contour replacement, making the serial expansion and drawing file saving of drawings with the same design rules more standardized and efficient.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A method for automatically expanding and locally saving tire product drawings based on contour replacement, the method comprising the following steps:

[0007] Step 1: Preparation for replacing the contour

[0008] Prepare the digital model containing replacement profiles and the configuration table, and the quantity and number of the replacement profile digital models should correspond one by one with the configuration table; for each replacement profile, the quantity and name of its release elements must be consistent;

[0009] Step 2: Place the profile digital model in the specified path for the program to automatically search and call according to the Code name in the configuration table, and create the configuration table into the full assembly digital model of the series extension to drive the replacement of the profile specifications and the update of the digital model;

[0010] Step 3: Matching check

[0011] In the digital model assembly, there are configuration tables for the profile, pattern, and sidewall. Check the matching of the tire specifications contained in each configuration table;

[0012] Step 4: Profile replacement

[0013] Search for and replace the profile digital model according to the valid configuration result, and automatically replace the profile digital model one by one; for each profile replacement, automatically replace the release elements with the same name of the profile digital model, complete the synchronous replacement of the external reference elements of the pattern and sidewall assembly nodes, and achieve upstream and downstream collaborative design;

[0014] Step 5: Configuration line extension

[0015] After the profile replacement is completed, start the automatic extension of all pattern and sidewall configuration lines under the replaced profile, complete the update of the digital model parts and drawing files, and extract all the design parameters of the digital model;

[0016] Step 6: Combine the digital model name and timestamp, and encode the necessary parts and drawings of the assembly digital model according to the digital model parameters obtained in Step 5;

[0017] Step 7: Automatically save the encoded parts and drawings locally; automatically create a folder with the name of the replaced profile's specifications, and save all the encoded drawing files updated and extended under the replaced profile.

[0018] Preferably, the inspection rules in Step 3 are as follows: Select the intersection specifications in the configuration table to search for the corresponding replacement profiles, and automatically ignore the non-intersection specifications; if there are no intersection specifications between the configuration tables, prompt that the valid configuration is 0 and the extension ends.

[0019] Preferably, the encoding rules in Step 6: Only encode the parts and drawings that need to be saved necessarily; for the parts with the same digital model parameters in Step 5, they have the characteristic of unique encoding and no new encoding is performed; for the parts with different digital model parameters, new encoding is generated; for the replacement profile digital model, since it is a digital model with an existing number, no new encoding is generated.

[0020] Preferably, this method is applicable to replace the full-assembly structure of the contour assembly pattern and the sidewall.

[0021] Preferably, this method is applicable to replace the assembly structure of two assembly components, namely the contour and the pattern.

[0022] Preferably, this method is applicable to replace the assembly structure of two assembly components, namely the contour and the sidewall.

[0023] Preferably, the said method is programmed through CAA to become an easy-to-use tool.

[0024] Furthermore, the present invention also discloses a computer device, including a memory, a processor, and a computer program stored on the memory, and the processor executes the computer program to implement the said method.

[0025] Furthermore, the present invention also discloses a computer-readable storage medium, on which a computer program or instruction is stored, and when the computer program or instruction is executed by a processor, the said method is implemented.

[0026] Furthermore, the present invention also discloses a computer program product, including a computer program or instruction, and when the computer program or instruction is executed by a processor, the said method is implemented.

[0027] Due to the adoption of the above technical solution in the present invention, the automatic expansion and local saving of the tire product drawings with contour replacement are adopted, so that when the contour design has been finalized, the expansion of the pattern and sidewall drawings can be more efficient and accurate. The automatic replacement of the contour drawing release elements is adopted to ensure the collaborative design of tire products with top-down design from the contour drawing. Especially for one-key replacement and expansion in the face of design changes, the efficiency of the full-assembly design is greatly improved, and mold processing errors are avoided. At the same time, when the program automatically expands in series, the generation and unique identification of local codes can be carried out according to part parameters, which is beneficial to the automatic and efficient saving management of drawing files, saves unified files for multiple configurations under the same contour, and improves the standardization of design drawing management.

[0036] The following will give a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings.

[0037] Step 1: Preparation of replacement profiles. It includes the preparation of digital - analog models containing replacement profiles and the preparation of configuration tables. The quantity and numbering of the digital - analog models of replacement profiles should correspond one - to - one with the configuration tables, as shown in Figure 1 . Requirements for digital - analog models of replacement profiles: The quantity and name of the released elements of each replacement profile must be the same, as shown in Figure 2 .

[0038] Step 2: Place the profile digital - analog models in the specified path for the program to automatically search and call according to the Code names in the configuration table. Create the configuration table in the fully - assembled digital - analog model of the series extension to drive the replacement of profile specifications and the update of digital - analog models.

[0039] The following steps are implemented by programming:

[0040] Step 3: Matching check. There are three parts of configuration tables, namely profiles, patterns and sidewalls, in the digital - analog assembly. Check the matching of tire specifications contained in each configuration table. Check rule: Select the intersection specifications in the configuration table to find the corresponding replacement profiles, and non - intersection specifications are automatically ignored, as shown in Figure 3 ; If there are no intersection specifications between configuration tables, it is prompted that the valid configuration is 0 and the extension ends, as shown in Figure 4 .

[0041] Step 4: Profile replacement. Search for and replace the digital - analog models of replacement profiles according to the valid configuration results, and automatically replace the digital - analog models of replacement profiles one by one. Each time a profile replacement is performed, the released elements with the same name of the digital - analog model of this profile are automatically replaced to complete the synchronous replacement of the external reference elements of the pattern and sidewall assembly nodes, realizing upstream - downstream collaborative design.

[0042] Step 5: Configuration line extension. After the profile replacement is completed, start the automatic extension of all pattern and sidewall configuration lines under the replaced profile, complete the update of digital - analog parts and drawing files, and extract all design parameters of the digital - analog model, as shown in Figure 5 .

[0043] Step 6: In the way of combining the digital model name and the time stamp, encode the necessary parts and drawings of the assembly digital model according to the digital model parameters obtained in Step 5. Encoding rules: Only encode the necessary parts and drawings to be saved; for parts with the same digital model parameters in Step 5, they have the characteristic of unique encoding and no new encoding will be performed; for parts with different digital model parameters, generate new encodings; for the replacement profile digital model, since it is a digital model with an existing number, no new encoding will be generated.

[0044] Step 7: Automatically save the encoded parts and drawings locally. Automatically create a folder with the specification of the replacement profile as the name, and save all the encoded drawing files extended and updated under this replacement profile, as shown in Figure 6 .

[0045] The above technical solution becomes an easy-to-use tool through CAA programming.

[0046] 1. Replacement profile preparation. It includes the digital model preparation of the replacement profile and the configuration table preparation, and the quantity and number of the replacement profile digital models should correspond one by one with the configuration table;

[0047] 2. Place the profile digital model in the specified path, and create the configuration table in the fully assembled digital model with series extension, so as to drive the replacement of the fully assembled specification and the digital model update;

[0048] 3. Start the program on the general assembly node of the program object, and present the program interface, as shown in Figure 7 ; The program automatically starts the matching check of the configuration table and the search for the replacement profile, and outputs the effective configuration results;

[0049] 4. After confirming that the effective configuration meets the extension requirements, custom-select the extension method and the drawing saving type in turn on the program interface, click the "Start" button to start the automatic extension of the tire product drawings under the replacement profile, the automatic profile replacement and the automatic configuration extension until all effective configurations are fully extended and the program ends;

[0050] 5. During the extension process, according to the principle of encoding uniqueness of part parameters, the program automatically encodes the extended parts and drawing files of each row of the configuration locally, and automatically saves the extended files in the folder named after the Size of the replacement profile.
