Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology for hydraulic supports, and more specifically, to an integrated design and manufacturing process method for hydraulic support components. Background Technology

[0002] Hydraulic supports are one of the most important mechanical equipment in fully mechanized coal mining faces, with structural components accounting for about 80% of the total weight of the hydraulic support. The manufacturing processes for hydraulic support structural components are complex and diverse. The process for creating structural component processes typically involves process engineers manually selecting appropriate part process templates and processing equipment based on the graphic features and dimensions of the design drawings in the process design software CAPP (Computer Aided Process Planning). Afterward, they calculate the main material quotas, process time calculations, and generate process cards to complete the process design work.

[0003] Chinese invention patent “A view-based method for organizing and expressing 3D MBD process models” (application number: 201811415097.7) describes a method for constructing 3D process models from the finished product model and linking them to the corresponding process organization structure tree nodes up to the blank model. Using the 3D process model and related process information in each process as input, a corresponding process model process view is constructed. Based on the relevant process information, the processing-related information of the process is generated. At the same time, annotation and annotation technology is used to realize the visual expression of various information required for the process, so as to fully and clearly express the process annotation of the process.

[0004] The drawback of this approach is that it is less efficient in creating process models for parts with long machining routes. Furthermore, while it uses annotation and commentary techniques to visualize the various information required for each step, it fails to effectively reflect the processing line, unit, equipment type, quota time, actual working time, and other effective process information, thus limiting its effectiveness.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an integrated design and manufacturing method for hydraulic support parts. This method enables automatic calculation of main material quotas for parts in various processes, automatic creation of process routes, automatic generation of equipment and work centers, automatic calculation of working hours, high efficiency in parameterizing the 3D model (MBD) of parts, and allows for reuse.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: an integrated design and manufacturing method for hydraulic support components, comprising the following steps: Step 1) In the CAD system, by establishing standardized part modeling methods, model features corresponding to part processes are created. Special features that are not easily distinguishable as to whether they have been machined are expressed through labeled 3D annotation information. Step 2) By batch identifying the model process features and labeled 3D annotation information, automatically extract the corresponding processing process name and corresponding process parameters and save them to the model parameters; Step 3) The extracted processing steps are automatically matched using the process route knowledge base. After permutation, combination and deletion, a unique process route containing all main processing steps is formed and saved to the model parameters. Step 4) When the part model in the CAD terminal is modified, execute steps 2) and 3) to update and save the model parameters; Step 5) Check the part model, process parameters and process route from the CAD end into the data pool of the Windchill system. According to the process matching rules, perform parameter verification and parameter parsing on the process parameters and process route parameters in the model. When parameters are missing or abnormal, an error reminder will be given, and the system will return to the CAD end for modification. When the parameters are correct, the corresponding design model or design part will be created. Step 6) Create the corresponding process BOM based on the design model or design component BOM; Step 7) Based on the process route and process parameters parsed from the created process BOM data pool, the material quota and auxiliary material quota are automatically calculated; at the same time, based on the process rule knowledge base in the CAPP process platform, the process route corresponding to the part is created, and the corresponding auxiliary process is automatically inserted according to the process rule knowledge base to form a complete process route. Then, the equipment and work center corresponding to the process are created according to the complete process route; the working time of each process is automatically calculated based on the working time calculation model library, thereby realizing the automatic generation of the design and process of hydraulic support parts.

[0008] This invention standardizes part modeling in the CAD system, then saves the part's process name and process parameters to the model's parameters. Based on the determined process name and parameters, the process route is then determined and saved in the model's parameters. Since these parameters are interconnected, modifications to the CAD model synchronously update and modify these parameters, achieving dynamic and autonomous updates. Furthermore, after the part model, process parameters, and process route are checked into the Windchill system, the Structured Process Platform (CAPP) reads data from the data pool and process rule knowledge base. This enables automatic calculation of process quotas for main and auxiliary materials of hydraulic support parts, automatic creation of process routes, insertion of auxiliary processing procedures, automatic generation of equipment, production lines, work centers, and automatic calculation of working hours—all the necessary data for automatic generation of hydraulic support part design and process.

[0009] Based on the above, the standardized part modeling method in step 1) refers to the modeling method built into the CAD software that can express the characteristics of the process. For example, bending parts are modeled using sheet metal modeling, bevel features are modeled using the chamfer command, and so on.

[0010] Based on the above, the labeled three-dimensional annotation information is used to indicate whether the part needs to be drilled, and of course, it also includes some special features that are not easy to distinguish whether they need to be processed.

[0011] Based on the above, the labeled 3D information is batch-identified using the model feature recognition function of the 3D CAD secondary development plugin. Specifically, the 3D CAD secondary development plugin is an extension function based on Creo Parametric software, which achieves automated design, parameter extraction, and function enhancement through a programming interface. The model feature recognition function uses the Pro / Toolkit secondary development interface provided by PTC for Creo Parametric. By calling the ProFeature series APIs, it directly accesses the feature data of the CREO kernel. The steps are: initialization → model acquisition → feature traversal → type identification → parameter extraction. The purpose of the secondary development plugin is to extract and use this function independently and execute it in batches to improve efficiency and save computing power.

[0012] Based on the above, the process route knowledge base in step 3) is stored in the 3D CAD secondary development plugin, and the process in step 3) used to form a unique process route containing all main machining operations is executed in the 3D CAD secondary development plugin.

[0013] Based on the above, in step 5), the data pool is a built-in functional module of the Windchill system.

[0014] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, this invention constructs an automatic generation method for the design process of hydraulic support parts. By combining the model parameters, process parameters, and process route parameters loaded in the three-dimensional part model with the process rule knowledge base in the Windchill system, a complete process route is constructed. Then, based on the complete process route, the equipment and work centers corresponding to the process are created. Finally, based on the time calculation model, the time of the process is automatically calculated. All of these contents together constitute the automatic generation of the design and process of hydraulic support parts.

[0015] Furthermore, the entire process of automatically generating the design and process of the constructed hydraulic support parts can be automatically updated based on the adjustment of model parameters.

[0016] Furthermore, in the redesign of 3D CAD part models, when new products can use parts containing model parameters and process routes, the process parameters and process route information in the part model can be quickly updated through regeneration, without having to redefine process parameters and other information, thus enabling the rapid generation and reuse of part processes. Attached Figure Description

[0017] Figure 1 This is the technical roadmap for the CAD side in this invention.

[0018] Figure 2 This is the overall technical roadmap for the integrated design and manufacturing process of hydraulic support components in this invention. Detailed Implementation

[0019] The technical solution of the present invention will be further described in detail below through specific embodiments.

[0020] like Figure 1 As shown, an integrated design and manufacturing method for hydraulic support components includes the following steps: Step 1) In the CAD system, by establishing standardized part modeling methods, model features corresponding to part processes are created. For example, bent parts are modeled using sheet metal modeling, bevel features are modeled using the chamfer command, and some special features that are not easy to distinguish whether they are processed, such as whether the part is drilled, are expressed by using 3D annotations with markings to express the part product definition information.

[0021] The core purpose of this step is to automate the modeling process by setting the modeling method according to the process characteristics of the standardized parts. Essentially, it gives the model some parameter characteristics that are combined with the process, so that it can form the basis for calling and matching other programs in subsequent steps.

[0022] Step 2) Use the model feature recognition function of the 3D CAD secondary development plugin to batch identify the model process features and the marked 3D annotation information, automatically extract the corresponding processing process name and corresponding process parameters and save them to the model parameters.

[0023] This step identifies the model features based on the modeling method established in step 1). For example, sheet metal modeling can identify sheet metal processes, thereby obtaining the corresponding processing process names and process parameters.

[0024] Step 3) The extracted processing steps are automatically matched using the process route knowledge base. After permutation, combination and deletion, a unique process route containing all main processing steps is formed and saved to the model parameters.

[0025] Since a part has multiple model features, by identifying all model features and obtaining the corresponding process names and process parameters, the process used to implement these processes can be determined. Then, by matching from the process route knowledge base, the corresponding process route can be obtained. However, it should be noted that since this step is at the initial stage of design, only the main processing processes are provided, and auxiliary processing processes are not considered at this time.

[0026] Step 4) When the part model on the CAD side is modified, execute steps 2) and 3) to update and save the parameters of the model; specifically, use the 3D CAD second-stage development plugin to batch extract and parse the changed process parameters of the hydraulic support part model, update and save them, and at the same time, batch read the process route knowledge base to update and save the process route of the sub-level part model.

[0027] This step enables the method to be dynamically adjusted and reused, allowing it to be applied in batches to the updating and upgrading of parts.

[0028] like Figure 2 As shown, in step 5), the part model, process parameters, and process route from the CAD end are checked into the data pool of the Windchill system. The process parameters and process route parameters in the model are verified and parsed according to the process matching rules. This process is automatically completed by the Windchill system. When parameters are missing or abnormal, an error message will be issued, and the system will return to the CAD end for modification. When the parameters are correct, the corresponding design model or design part will be created.

[0029] This step completes the data transfer process between different endpoints, and the Windchill system has powerful parsing, coordination, and processing capabilities. Step 6) Create the corresponding process BOM based on the design model or design component BOM.

[0030] Step 7) Based on the process route and process parameters parsed from the created process BOM data pool, the material quota and auxiliary material quota are automatically calculated. At the same time, based on the process rule knowledge base in the CAPP process platform, the process route corresponding to the part is created, and the corresponding auxiliary process is automatically inserted according to the process rule knowledge base to form a complete process route. Then, the equipment and work center corresponding to the process are created according to the complete process route. Based on the time calculation model library, the time of each process is automatically calculated. In this way, the hydraulic support part design process is carried out simultaneously through the integrated design and process system, and the hydraulic support part process is automatically generated.

[0031] In this process, the process rule knowledge base is a basic model library established by experts based on different processing process rules. It can be templated according to the needs of the processing process and configured with corresponding auxiliary processes based on the main process route to form a complete process route. The time calculation process relies on the time calculation of each process link. Combined with the automatic calculation of material quotas and auxiliary material quotas, the integrated design and process method of standardized parts can be realized.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
