Shulou(Shulou.com)06/02 Report--

Tianrun Crankshaft Co., Ltd. (Tianrun Crankshaft), is China's largest professional manufacturer of crankshafts, the production of "Tian" brand crankshaft is "China's recognized brand-name products". As an A-share listed company, Tianrun crankshaft business involves internal combustion engine power parts, railway equipment and machine tool equipment development and other fields. The leading products have a domestic market share of more than 40%, and are exported to more than 20 countries and regions along with the mainframe, some series of products and castings are directly exported to famous foreign companies such as South Korea, India, Turkey, Britain, Italy, Japan, the United States and so on.

Build Core Competitiveness and seek benefits from efficiency

The main business of Tianrun crankshaft has formed seven main business sectors: ship machinery, heavy truck, light truck and car crankshaft, as well as connecting rods, castings and forgings. Since its production mode, map processing and multi-department cooperation are the main. How to improve the efficiency of product research and development, quickly convert process documents, ensure product processing quality, and realize knowledge sharing within the enterprise at the same time, so as to build the core competitiveness of Tianrun crankshaft, it is an urgent problem to be solved by the technical R & D and production department of Tianrun crankshaft.

In view of the above hopes, the solution given by Huatian Software is to optimize the technological process and seek benefits from efficiency.

Process BOM management: by copying the product design BOM, the initial process BOM is formed and the process structure is created in batch. In the process route editing environment of parts and components, the process route unit is selected to design the process route of new products and parts.

Standardized customized process card: design standard process card template and support template import in Excel format.

Associate and manage quality system documents to improve work efficiency: use process cards to compile quality system documents, easily call process file templates, and generate process flow charts, PFMEA, control plans, and automatically prompt updates and associated updates when changes are made.

Key application description

1. Structurally manage process data, determine all kinds of process routes, clearly guide all aspects of product processing, and improve the efficiency of process planning.

The process data is organized in a structured way, and the process data is divided into parts, process routes (divided into first-level and second-level process routes) and process files, which is convenient for statistical summary of all kinds of data in the later stage. At the same time, a complete set of files can be copied.

According to the machining characteristics of the crankshaft, the first-level process route unit is equipped with machining, casting, forging and so on, and the second-level route unit is mainly based on the specific processing process. The secondary process route is generated automatically through the process flow chart.

To realize the correlation management of process documents, solidify the documents under the second-level process route, and only allow the corresponding PFMEA, control plan and operation instructions of the process to be connected.

two。 Establish enterprise equipment resource database, standardize process card design, associate product attributes, and improve enterprise process standardization work.

Aiming at the machining process, it standardizes the process management, defines various machining process names and process types, and maintains the equipment information used in each process to the process resource database.

When compiling the machine processing process flow chart, the process name, equipment type and equipment name information are obtained directly from the resource database, and the process flow chart is automatically generated according to the process name and process type selected by the user.

3. Formulate strict quality system documents to prevent product quality in the bud.

Due to the relatively perfect process of Tianrun crankshaft, after years of accumulation, it has formed the accumulation of PFEMA, control plan and other process information. The CAPP system optimizes the compilation of PFEMA, control plan and other documents, and significantly improves the efficiency of process planning.

According to the conditions such as the failure mode of process content, the PFMEA file automatically obtains FMEA information in the resource database, and generates PFMEA files in batches. During the batch generation of PFMEA, the PFMEA information is extracted from the resource database according to the specific machining process of each part. As the PFEMA information is relatively perfect, the automatically generated PFMEA files after filtering basically do not need to be adjusted.

4. process card management to ensure the integrity of the change process and reduce the production errors of the changed products.

According to the crankshaft processing process characteristics, after the analysis of each type of documents, finally determine the relevant content of the Tianrun crankshaft process file, including the work instruction and the process plan, from the process drawings to the control plan. When the related information in the process drawing changes, the related content in the control plan will change automatically. For other information in the control plan, the corresponding control plan file is automatically generated according to the process name, product, characteristics and other contents according to the control plan resource base.

5. Optimize the process design at the same time to improve the ease of use of the system and improve the efficiency of process design.

Using the experience of superior industries for reference, the design of process cards is optimized.

● optimizes graphics operation and makes it easy to resize graphics.

● optimizes the process card making process by adjusting cell size, matching line height according to content, and automatically typesetting to ensure the printing effect.

● automatically extracts the labeling and engineering symbol information from CAD drawings and converts them into process files.

Excellent management, present effect

The structured management of ● process makes it convenient for designers to design the process according to the specific process.

● process files are related to each other, which saves the time for designers to compile process documents and improves the accuracy of process documents.

The batch generation or update of ● process files realizes the automatic generation of process cards, which saves the efficiency and speed for designers to create new process files.

The association between ● process files and resource library saves the time of manual input when designers edit cards and improves work efficiency.
