Description

Technical Field

[0001] The present invention relates to the technical field of mold manufacturing process design and manufacturing management, and in particular to an application method, storage medium and equipment for compiling a mold manufacturing process route. Background Art

[0002] Each component of an automotive stamping die requires the sequential processing of multiple dies, including blanking, drawing, trimming, and flanging dies. Each die set contains numerous components, multiple manufacturing processes, and complex assembly relationships. Most parts have complex shapes, and the machining process is complex and varied, with the order in which each component is processed interdependently. Consequently, die manufacturing process design and management are unique and complex.

[0003] In the current mold manufacturing process, most technicians develop process templates based on different mold process types (such as blanking dies, drawing dies, trimming dies, and flanging dies). They then develop process routes based on experience for specific mold types (such as size, material, number of inserts, whether wedge cutting is required, etc.). Furthermore, the current mold manufacturing process and production management are largely independent of each other, and information cannot be shared, which can easily lead to the following problems:

[0004] 1) Low degree of process standardization

[0005] Although the industry has established operating standards for current mold manufacturing processes, these standards are relatively rough and cannot cope with the process information required to generate single customized parts. Operating standards are generally electronic or paper documents, and in actual operations, operators rely heavily on manual judgment, resulting in a high level of quality problems in mold manufacturing.

[0006] 2) There is a big difference between process parameters and actual characteristics

[0007] In actual operations, the particularities of each product are inconsistent, and the amount of information on the characteristic points that affect the process is large, which requires manual identification by process personnel and the design of the process based on experience. This will often lead to problems such as missed processing, low processing accuracy and overcutting.

[0008] 3) Decoupling of process from production plan and actual production rhythm

[0009] Each process schedule was essentially a one-size-fits-all approach, with workload assessments and production planning based on management's experience. This made the entire production process uncontrollable, and processes often became disconnected from production plans and actual production pace.

[0010] 4) Unable to accurately establish cost and quotation models

[0011] The industry's costs and quotations for molds and parts are mostly evaluated and calculated based on rough data, and are unable to be refined to the parts and process levels, resulting in distorted cost and quotation models.

[0012] In summary, it is necessary to develop an application method, storage medium and equipment for compiling a mold manufacturing process route to solve the problem of information sharing between mold manufacturing process and production management in the existing technology. Summary of the Invention

[0013] The present invention aims to provide a mold manufacturing process route compilation method, application method, storage medium and equipment. The specific technical solutions are as follows:

[0014] In a first aspect, the present invention provides an application method for compiling a mold manufacturing process route, comprising:

[0015] Step S1, using MYSQL software to establish a database; the database includes a parts parameter library, a process parameter library and a resource parameter library;

[0016] Step S2: importing the three-dimensional model of the target part into the UG software and performing feature recognition according to the color number in the process parameter library to obtain various feature parameters; matching each of the feature parameters with the corresponding parameters in the part parameter library to obtain an instantiated part data model of the target part;

[0017] Step S3: using the GC toolbox in the UG software to calculate the instantiated part data model obtained in step S2 and the corresponding process route in the process parameter library, and retaining the corresponding process nodes if the calculation result is greater than 0; and automatically compiling the mold manufacturing process route of the target part in the UG software based on the retained process nodes using the SAM module;

[0018] Step S4: Based on the mold manufacturing process route obtained in step S3, the UG software is used to call the adapted machine tool model in the resource parameter library and instantiate the processing program, which is uploaded to the machine tool to complete the processing of the target part, and the processing data and quality data are collected during the processing;

[0019] Step S4 also includes the UG software storing the collected processing data and quality data in the database for modifying the part parameter library, modifying the process parameter library and modifying the resource parameter library.

[0020] Optionally, in step S3, the corresponding process node is discarded if the calculation result is less than 0; the GC toolbox is continued to be used to calculate the instantiated part data model obtained in step S2 with the corresponding process node in the process parameter library until the calculation result is greater than 0.

[0021] Optionally, in step S2, each of the feature parameters includes a surface, a hole, and a line.

[0022] Optionally, in step S1, the parameters included in the part parameter library include standard part parameters.

[0023] Optionally, in step S1, the parameters included in the part parameter library also include non-standard part parameters.

Specifically, the present invention adopts step S1 to establish a database using MYSQL software based on the manufacturing process knowledge and production management experience accumulated by the enterprise, and the database includes a part parameter library, a process parameter library and a resource parameter library; in step S2, the instantiated part data model of the target part is obtained by matching the UG software with the part parameter library; in step S3, the instantiated part data model is calculated with the corresponding process route in the process parameter library using the GC toolbox to obtain the retained process nodes, and the mold manufacturing process route of the target part is automatically compiled using the SAM module; in step S4, the UG software is used to call the adapted machine tool model in the resource parameter library and instantiate the processing program, so that the matching degree between the process output program and the actual processing machine tool is improved, which can greatly improve the processing accuracy of the part and reduce the occurrence of processing abnormalities. Therefore, the present invention uses MYSQL software to establish a database, obtain an instantiated part data model of the target part, automatically compile the mold manufacturing process route of the target part, and complete the processing of the target part, greatly improving the standardization of process design and work efficiency. Specifically, the process compilation efficiency is improved by 100%, and the process quality abnormality is reduced by 50%. In addition, in step S4, the present invention uses UG software to store the collected processing data and quality data in the database for correction of the database, that is, the on-site processing is linked to the correction of the database, realizing information sharing between the mold manufacturing process and production management, further improving the standardization of process design, such as labor time quota management, early prediction of the company's production capacity, reducing process waiting waste, and accurately predicting the production cycle of new projects and the cost of making new molds.
