Automobile manufacturing industry increase the forming machine
Abstract: Because of mold materials and mold a special structural limitations, the current domestic automobile body stamping dies abroad, the same technology level and there is still a certain gap between sectors. This is mainly manifested in the process design experience and experienced staff, the domestic process designers have come into contact with the types and models of foreign compared to the difference between process designers too much, resulting in process design thinking by a number of constraints.
Japan's Toyota, Volkswagen and other leading automotive manufacturers, there are specialized stamping, welding, assembly, painting technology staff. R & D center with the designers of the body together with analysis of technology products.
From the body design to the equipment manufacturers have followed the principle of unity, the integration is very high, very much in favor of the quality of the body, cost, complete control cycle. China's mold, most of welding industry fragmentation folder, mold factories, welding it is difficult to communicate between the folder factories, many problems remain to car manufacturers in the production of the preparation phase, BIW has seriously hampered the product quality and output cycle.
Because of mold materials and mold a special structural limitations, the current domestic automobile body stamping dies abroad, the same technology level and there is still a certain gap between sectors. This is mainly manifested in the process design forming machine experience and experienced staff, the domestic process designers have come into contact with the types and models of foreign compared to the difference between process designers too much, resulting in process design thinking by a number of constraints.
Stamping process planning abroad is a highly professional job, a clear division of labor required to complete the adoption of teamwork in the design of this complex process, in general, including pre-process product analysis, process planning forecast modeling, feasibility analysis process, model optimization of the design process repeated.
Wai-side to the whole car as an example, the common side Wai dies in general for 5 ~ 6 processes. Four years ago, Toyota of Japan to the side from the five Wai processes into four processes, and in the mold development and product development efforts in the industry to achieve a big leap. The direction of the current study three processes through the completion of the overall side-Wai stamping process, which not only enhance the need for stamping process, but also the need for collaborative concurrent engineering research and development, the whole car in the design of the product side of Wai, it is necessary to give full consideration to the punch the feasibility of technology.
Some of the advanced international enterprise with a high level of welding development capacity, and formed a small number of vehicles with advanced welding technology platform as the core of the enterprise, many highly specialized welding of small and medium-sized enterprises Collaboration pattern. Abroad such as Japan's Toyota, Volkswagen, Peugeot, General Motors Corp. and other major application of three-dimensional digital process planning and simulation software for nearly ten years of history. Domestic production, and a high degree of automation of the assembly line process planning of a lack of unified management of digital information, there is no formation of such highly automated assembly line planning capability.
China's auto white body of the equipment manufacturing industry in terms of quantity present or have been close to nature on the level of the world's leading. According to incomplete statistics, only car mold industry as an example, large-scale NC machine tools have the capacity has exceeded 800, but because of our late start, lack of accumulation, the level of manufacturing technology with the international advanced level there is still a wide gap between. To die in China from a big country into a powerful tool, the industry needs to make persistent efforts.
Supporting China's automotive industry behind mold, material types, material properties of instability. These issues include: the standard variety, quality is not high; the gap between the level of manufacturing process led to processing costs than foreign manufacturers; induction hardening / laser quenching / TiN / Ti, and so on to be the edge of technology development; debugging after the stamping process of data feedback and experience, lack of effective measures will be fitter in the process of commissioning into the design of pre-trimming; the lack of system management procedures and the ability to escalate.
