The design and manufacture of automotive body cover molds is the most critical part of the entire automotive industry and is the longest part of the automotive development cycle. Therefore, shortening the design and manufacturing cycle of automobile body cover parts is of great practical significance for improving the development and design of automobiles.
As the pace of international integration continues to accelerate and market competition is increasing, people are increasingly aware of the importance of product quality, cost and ability to develop new products. Mold manufacturing is one of the most basic elements in the entire chain. Mold manufacturing technology has become an important indicator to measure the level of manufacturing in a country, and to a large extent determines the survival space of enterprises.
In recent years, the mold industry has been developing rapidly with a growth rate of about 15%. All the manufacturing points of mold industry enterprises have undergone tremendous changes. In addition to the state-owned professional mold factories, collective, joint venture, sole proprietorship and private sector have also developed rapidly. The “hometown of molds” in Ningbo and Huangyan areas of Zhejiang Province; some large group companies in Guangdong and rapidly rising township enterprises, Kelon, Midea, Konka and other groups have established their own mold manufacturing centers; Sino-foreign joint ventures and wholly foreign-owned mold companies are now There are already thousands of them.
Many mold companies have increased their investment in technological advancement and regarded technological progress as an important driving force for enterprise development. Some domestic mold companies have popularized two-dimensional CAD, and have begun to use UG, Pro/Engineer, I-DEAS, Euclid-IS and other international software. Some manufacturers have also introduced Moldflow, C-Flow, DYNAFORM, Optris and MAGMASOFT. CAE software has been successfully applied to the design of stamping dies.
The manufacturing technology of large-scale stamping dies represented by automobile cover moulds has made great progress. Diemakers such as Dongfeng Automobile Company Mould Factory and FAW Mould Center have been able to produce some car cover moulds. In addition, many research institutes and universities have conducted research and development of mold technology. After years of hard work, significant progress has been made in mold CAD/CAE/CAM technology; contributions have been made in improving mold quality and shortening mold design and manufacturing cycles.
For example, KMAS software for stamping and forming of automobile panels independently developed by Jilin University Automotive Panel Forming Technology, injection molds, automotive panel molds and progressive die CAD/CAE/CAM software developed by the State Key Laboratory of Mould Technology, Huazhong University of Science and Technology The cold die and fine die CAD software developed by the cold die and fine punch research center developed by the National Engineering Research Center of Shanghai Jiaotong University, have many users in the domestic mold industry.
Although China's mold industry has achieved remarkable development in the past decade, many aspects still have a large gap compared with industrial developed countries. For example, the proportion of precision processing equipment in mold processing equipment is relatively low; the penetration rate of CAD/CAE/CAM technology is not high; many advanced mold technology applications are not widely used, etc., resulting in a considerable part of large, precise, complex and long life molds. Dependent on imports.
Today, all countries in the world regard the automobile industry as one of the pillar industries of the national economy, and the competition is becoming increasingly fierce. An important indicator of the development level of the automotive industry, especially the car industry, is the independent development and design capabilities of the models. The state requires that in 2010, China's auto industry, especially the sedan industry, will have the self-design and development capabilities of models and molds, and truly establish a self-developed Chinese auto industry. By 2010, the automobile industry will have a production capacity of 5 to 6 million vehicles, of which 70% will be cars. According to the National "Outline for the Revitalization of the Automobile Industry", the focus of the development of the automotive industry in the future is the localization of cars and car parts. According to the development strategy of “two steps” in China’s car production (that is, the first step is to engage in the body and the second step to engage in the engine), it will be a period of great development for China’s automobile industry in the next 10-15 years, which is for China. Automotive manufacturing technology places higher demands on it.
The development level of the car industry is a symbol of national economic and technological strength. In the whole cycle of research and development and commissioning of new models, mold design and commissioning takes the longest time. Automotive body molds, especially large and medium-sized cover molds, are technically intensive and reflect the level of contemporary mold technology. They are an important part of the body manufacturing technology. Body mold design and manufacturing accounted for about two-thirds of the car development cycle, becoming the main constraint for car replacement. However, through the computer simulation forming process, combined with the advanced CAD / CAM / CAE system, the local structure of the mold can be repeatedly corrected on the computer to achieve the optimization of the mold structure design, a success. By greatly shortening the mold debugging cycle, reducing the cost of molding, and accelerating the replacement of the model, the international market competitiveness of the product can be greatly enhanced.
Body molding technology is one of the key technologies in the automotive industry, and the body panel forming technology is the key to the manufacture of automobile bodies. The body cover occupies an important position in the whole vehicle. However, the cover mold is the main process equipment for producing the cover, which plays a decisive role in the quality of the vehicle body: it is directly related to the quality and appearance of the automobile product. Production costs, production and development cycles, and the important role of accelerating the upgrading of automotive products and shortening the development cycle have attracted great attention at home and abroad. One of the keys to the development of the automotive industry is the body, the key to the body manufacturing is in the mold, and as a high-tech technology for the development of the automotive and mold industry, the CAD/CAE/CAM integrated system has become a magic weapon for domestic and foreign automobile companies to win.
