【正文】 。 State Development Planning mission, The Ministry of Science and Technology issued the current priority to the development of the hightech industry focus areas Guide has identified priority areas of the automobile is mainly concentrated in the automobile parts manufacturing industry. Auto industry, the small, lightweight and highspeed The direction of development, provides great opportunities for the development of the auto parts 60% is fing methods of production. The expert analysis: the United States, Japan, Germany’s, auto industry is so advanced, benefit from the fing technology and equipment of the leading position. China39。s fing industry must adapt to international petition after WTO accession, so we must arm ourselves with new and high technology and upgrade ourselves, unswervingly follow the selfphysically strong path of the sophisticated, specialization and modernization. At present, the development of China39。s automobile industry has bee a diversified trend, particularly the development of family cars, to meet the demands of different consumers, the car market has bee a multibrand, multispecies mon development pattern, so fings will inevitably lead to the diversification of demand, in order to meet market demand. Fing industry should give priority to how to make production more flexible to acmodate multiple varieties and Small Batch timely production requirement in nearly 10 years. Ⅱ The fing industry sector’s technological progress 太原科技大學(xué)畢業(yè)設(shè)計(jì)（論文） 37 Fing Industry major technological advances in the performance of new materials, new techniques and new equipment. Application of new materials. According to the information shows that the production in Germany at fing increasingly widespread use of microalloy steel. Due to Process in the followup to cancel the heat treatment process, the fing of such costs has dropped, Steel used in the manufacture of fings Fing immediately after rapid cooling, so cyanide will be enhanced by finegrained, thus decided the fing’s better mechanical properties. Lightweight vehicles also will lead the high proportion of employ magnesium, aluminum, titanium increasing. At the sometime nonferrous metal fings demand is rising. Alloy has a lower temperature in fing. Moreover it has a small temperature range, between its starts and ends. So that Forming velocity and the forming equipment which corresponded to are higher pared with the ordinary Fing. The application of new materials improve the fing equipment and process requirements, and thus their value to their products has been high. According to statistics, the United States, Canada accounted for fing 5% of the total steel fings sales accounted for fing total sales of 20%. Application of new technology. The socalled precision that is widely used for shape technology, through the application of new technology to achieve little without the purpose chip. For instance the shaft wedge rolling, roll fing technology。 Disktype parts Warm Fing technology, placed crushed。 fork parts of the pieces, multimode Boring forming technology。 plex parts powder fing technology, and so on. The socalled professional is the new techniques in terms of various types parts manufacturing relative specialization. Application of new technology will not only save a great amount of material, but also enhance the production efficiency, improve the fing internal and external quality. Application of new equipment. As new materials, new technology application, corresponding to the forming equipment obtained a broad space for development。 fing equipment is developing gradually to the high efficiency, high accuracy, high reliability, low energy consumption direction. China fing industry factories scattered, backward technology, fing aging equipment, general Fing’s production capacity is very surplus, but the capacity is obviously inadequate, that can achieve the standard of DIN7526E precision fings level of productivity which Germany will be able to achieve. With a big gap between the foreign, in 太原科技大學(xué)畢業(yè)設(shè)計(jì)（論文） 38 order to meet demand of the international market and fing industry promote a reform of specialization。 the other hand, it should also meet the multiple varieties and small batch production requirements in a timely manner。 At the same time, fing industry should vigorously promote the reform process, and use new equipment, actively realize modernization fing industry has bee large enterprises fing go out into the world and meet the world and pete with the peer. Ⅲ Fing hammer’s status and adaptability in the modern industrial technology development Fing hammer is a multifing machines’ pioneer which has been 100 years of history. Despite various fing new techniques and new equipment are constantly emerging, fing hammer still plays a very important role because of its simple structure, convenient operation, Forming fast, strong adaptability and the advantages of low investment. Especially the emerging of the programmable hydraulic fing hammer, that has made fing hammer a renaissance in modern technology development. Hammer has a distinct advantage against faster, thus mold exposure time is short. So it is particularly suited to the requirements of highspeed deformation mold filling occasions. For example, with thin bars plate, the plex shape and weight tolerances are required fings. Because of its rapid and flexible operating characteristics, its adaptability is very strong, and it was known as the universal equipment. Therefore fing is particularly suitable for multiple varieties and small batch production. Hammer is the optimal costforming equipment. Hammer Rapid Prototyping characteristics has been brought into full play not only in the hot fing forming technology, but also Cold Forming in the application of the process. According to rel
