Description

Technical Field

[0001] This invention relates to the field of hydraulic support design technology, and more specifically, to a method for managing the cutting drawings of multi-process parts of hydraulic supports based on CREO. Background Technology

[0002] Hydraulic supports are the core support equipment for fully mechanized coal mining faces. The production process of structural plate components is quite complex, including cutting, forming, and machining processes. For equipment with different processing precision, different blanking drawings with different allowances are required. Traditionally, the blanking drawings for hydraulic supports are mainly drawn manually using CAD software or generated using other computer-aided tools. When the production equipment changes or the manufacturer makes adjustments, the blanking drawings need to be repeatedly modified, which is time-consuming and labor-intensive.

[0003] On September 20, 2024, a Chinese invention patent application entitled "Method, System, Storage Medium, and Electronic Device for Generating Sheet Metal Cutting Drawings Based on Autodesk Inventor" (Publication No.: CN118674861A) was published. The disclosed method for generating sheet metal cutting drawings based on Autodesk Inventor includes: obtaining part information of multiple sheet metal 3D model parts that can be processed into sheet metal parts through sheet metal cutting, based on an assembly comprising multiple 3D model parts; and generating multiple sheet metal cutting drawing sets by one-click output of the obtained part information of the multiple sheet metal 3D model parts. While this solution can generate multiple sheet metal cutting drawing sets by one-click output of the obtained part information of the multiple sheet metal 3D model parts, it still has the following four drawbacks: 1. The required 3D model must be modeled in sheet metal mode. Sheet metal mode modeling not only requires high design capabilities, but also requires converting the completed 3D model into a sheet metal part before it can be used. 2. Sheet metal models require inputting structural feature parameters in the command form, which greatly increases the workload of model preparation and reduces work efficiency. 3. For normal non-sheet metal parts, it is impossible to generate blanking drawings; 4. It is impossible to manage and output blanking drawings for multiple processes on the same part.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0005] Therefore, it is necessary to provide a method for managing the blanking drawings of multi-process hydraulic support parts based on CREO to address the aforementioned technical problems. This method classifies and combines the process characteristics of the same part under different machining processes (such as milling, drilling, boring, etc.) and generates corresponding numbered sketches, thereby achieving automated, standardized, and traceable management of blanking drawings. This significantly improves the efficiency of production planning, reduces human error rates, and provides reliable technical data for subsequent CNC machining.

[0006] To achieve the above objectives, the first aspect of the present invention provides a method for managing the blanking drawings of multi-process hydraulic support parts based on CREO, comprising: Step 1: Determine the process characteristics of the blanking diagrams required for different processes, and classify and combine these process characteristics.

[0007] By using a pre-established rule-based judgment table, complex process requirements are abstracted into machine-recognizable feature codes, achieving standardization and reusability of process features. This enables the rapid location of the blanking diagram requirements corresponding to each processing method, solving the problems of time-consuming and error-prone traditional manual judgment.

[0008] Step 2: Draw sketches with different numbers corresponding to different process features of the same part.

[0009] In step 2, for the same part drawing, the allowance of different processes is used as a feature. After combining and arranging the features, multiple process feature combinations are obtained. For each process feature combination, a corresponding sketch is drawn and numbered to form a multi-process sketch template library based on the part body.

[0010] Each process feature is mapped to an independent sketch and numbered, enabling multiple drawings for a single piece and ensuring traceability of the drawings. During subsequent automated output, the corresponding blanking drawing can be accurately retrieved simply by its number, avoiding manual searching and repetitive modeling, and improving the collaborative efficiency between design and manufacturing.

[0011] Step 3: Based on the drawn sketch, generate multi-process cutting drawings for the part, and then save the generated multi-process cutting drawings for the part into the process platform of the PLM product lifecycle management system.

[0012] In step 3, multiple sheets are created in the CREO drawing, with each sheet number corresponding to the sketch number. Then, the sketches of the same part with different numbers are projected onto the corresponding sheet pages, thus forming a multi-process cutting drawing for the part.

[0013] By embedding logical judgments within the part model, the model achieves built-in process decision-making functionality, meaning the model itself can automatically determine which cutting drawing to use based on input dimensions or parameters. This mechanism eliminates the need for external manual matching, making the design more intelligent and maintainable.

[0014] Step 4: In the part relationship page of the CREO software, write the corresponding process judgment conditions for the part; when drawing is required, use the CREO tool to determine the blanking drawing page number determined by the written conditions based on the determined process features, and then output the process blanking drawing required for the part.

[0015] In step 4, when building the part model in Creo, the process features for determining the part's process conditions are numbered and named. In the part relationships within Creo, the condition is written: when the size of A changes, different blanking drawings are selected. Automated export avoids dimensional errors caused by manual copying and pasting.

[0016] The CREO tool acts as a bridge, transforming the internal logic of the model into actual drawing output, achieving "one-click drawing generation." This significantly improves the speed and accuracy of material cutting drawing generation, while avoiding the risks of version confusion or missing drawings caused by manual operation.

[0017] This invention provides a complete and efficient solution for managing the blanking drawings of multi-process hydraulic support parts through a closed-loop process: "process rule judgment table → feature combination → numbering sketching → template library → automated software implementation." This solution not only meets the existing demand for rapid generation of multi-process blanking drawings but also provides reliable technical support for the digital transformation of manufacturing enterprises through an integrated software / hardware implementation.

[0018] Based on the above, a second aspect of the present invention provides a multi-process parts blanking management system for hydraulic supports based on CREO, comprising: The process feature determination module is used to determine the process features of the blanking diagram required for different processes, and to perform combination and classification processing of the process features; The sketching module is used to draw sketches with different numbers corresponding to different process features of the same part; The part drawing generation module is used to generate multi-process part cutting drawings based on the drawn sketches, and then store the generated multi-process part cutting drawings into the process platform of the PLM product lifecycle management system. The blanking drawing output module is used to write the corresponding process judgment conditions for the part in the part relationship page of the Creo software, and use the Creo tool to determine the blanking drawing page number determined by the written conditions, thereby outputting the process blanking drawing required for the part.

[0019] A third aspect of the present invention provides a computer device, comprising: One or more processors; Memory, used to store one or more programs. When the one or more programs are executed by the one or more processors, the one or more processors perform the steps of the CREO-based hydraulic support multi-process parts blanking drawing management method as described above.

[0020] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the CREO-based multi-process parts blanking diagram management method for hydraulic supports.

[0021] A fourth aspect of the present invention provides a computer program product, including a computer program / instruction that, when executed by a processor, implements the steps of the CREO-based hydraulic support multi-process parts blanking diagram management method as described above.

[0022] The beneficial effects of this invention are as follows: 1. Capable of drawing multiple process blanking sketches from the same part model; 2. Manage and select output of multi-process material cutting diagrams based on Creo; 3. No model parameters need to be filled in during the creation of cutting drawings, which reduces the workload of model preparation, reduces manpower time costs, and improves work efficiency; 4. Multi-process sketching can be performed on models that are not sheet metal parts, reducing model modification costs; after writing judgment conditions, the blanking drawings for various processes are output based on CREO judgment, improving the accuracy of the output drawings. Detailed Implementation

[0023] The technical solution of the present invention will be further described in detail below through specific embodiments.

[0024] To facilitate understanding, the interactive parties and / or terms and / or custom terms involved in this invention will first be explained in conjunction with the technical solution of this invention: Example 1

[0025] This embodiment presents a method for managing the blanking drawings of multi-process hydraulic support parts based on CREO, including: Step 1: Establish a process characteristic judgment table After determining the process characteristics of the blanking diagrams required for different processes, and combining and classifying the process characteristics, a process characteristic judgment table is established.

[0026] ① Each factory has developed a part processing technology rule judgment table based on its own processing capabilities. The process characteristics of the required blanking drawing, such as milling, drilling, and boring, can be determined according to this part processing technology rule judgment table.

[0027] By collecting information on machine tool models, tool libraries, and machining capabilities from various production bases, a "Process Rule Judgment Table" is constructed. The table lists the optional machining processes (milling, drilling, boring, etc.) for each part, along with key parameters such as dimensional tolerances and feed rates. During subsequent automatic matching, the system uses this table to quickly determine which type of blanking drawing needs to be generated, ensuring that the solution matches actual production capacity.

[0028] ② Extract process characteristics and classify them in combination; Process features include the length and width dimensions of the part, the size of the pre-cut holes, etc. These process features are then combined and categorized, such as modifying or eliminating the pre-cut hole diameter while keeping the length and width dimensions of the sheet metal unchanged.

[0029] Specifically, geometric dimensions (length, width) and reserved machining hole dimensions are read from the CAD part model. These features are then marked as "consistent / inconsistent" according to the process rule judgment table: if a process only changes the hole diameter while maintaining the sheet metal dimensions, it is marked as "consistent length and width, inconsistent hole diameter". This binary classification generates all possible combinations of process features, providing a basis for subsequent sketch numbering.

[0030] Step 2: Draw sketches with different numbers corresponding to different process features of the same part; Specifically, for the same part drawing, the allowance for different processes is used as a feature. After combining and arranging the features, multiple process feature combinations are obtained. For each process feature combination, a corresponding sketch is drawn and numbered according to the allowance requirement.

[0031] If two sketches numbered 1 and 2 are drawn on the same part, the sketch numbered 1 corresponds to the milling process feature, and the sketch only shows the length and width of the part; the sketch numbered 2 corresponds to the drilling process feature, and the sketch does not show the length and width of the part.

[0032] Specifically, open the original part model in CREO Sketcher, and create an independent sketch file for each combination obtained in steps 1-2. Assign a unique number to each sketch (e.g., 1, 2…), and retain only the dimensional scaling information corresponding to that process in the sketch: Milling sketch (No. 1): Only shows the tolerance enlargement of the length and width of the plate, while the hole positions remain at their original dimensions; Drilling sketch (No. 2): Do not make allowances for the overall dimensions, only retain the machining tolerance of the hole diameter.

[0033] In this way, each cutting diagram contains only the change information required for that process, avoiding confusion and improving the readability and efficiency of the drawings.

[0034] Create individual sketch files for all combinations obtained in steps 1-2, thereby generating a multi-process sketch template library: Determination of production scale characteristics for different processes: 1) Feature 1: Distinguished by cutting process; 2) Feature 2: Differentiation based on cutting process; By arranging and combining the above two features, a multi-process sketch template library based on the part itself is formed: Template Number Process feature combination Process scheme Template 1 Feature 1 is consistent, Feature 2 is inconsistent Sketch 1 Template 2 Feature 2 is consistent, Feature 1 is inconsistent Sketch 2 Template 3 Features 1 and 2 are inconsistent Sketch 3 Specifically, all numbered sketches are categorized according to "feature consistency" (such as whether the length and width dimensions are consistent, whether the aperture is consistent), forming a template library. Each template records: ① template number; ② description of the corresponding process feature combination; ③ associated sketch file; In this way, when a new part enters the system, the required cutting drawing can be quickly generated simply by searching for a matching template, greatly reducing the time engineers spend manually drawing it.

[0035] Step 3: Based on the drawn sketch, generate multi-process cutting drawings for the parts, and then store the generated multi-process cutting drawings for the parts into the process platform of the PLM product lifecycle management system. Specifically, multiple sheets are created in the CREO drawing, with each sheet number corresponding to the sketch number. Then, the sketches of the same part with different numbers are projected onto the corresponding numbered sheet pages, thus forming a multi-process cutting drawing for the part.

[0036] Step 4: In the part relationship page of the CREO software, write the corresponding process judgment conditions for the part, and use the CREO tool to determine the blanking drawing page number determined by the written conditions, thereby outputting the process blanking drawing required for the part.

[0037] Specifically, when building a part model in CREO, the process features of the part's process judgment conditions are numbered and named. In the part relationship in CREO, the judgment conditions are written so that different blanking drawings are selected when the size of A changes. Example 2
