Chinese mechanical engineering technology not only has a long history and splendid achievements in Chinese is not only the material culture and social economic development plays an important role in the world, and to promote the progress of civilization, technology has made great contribution to Chinese traditional machine. And in a long period ahead in the world. In modern times, especially from the early 18th century, due to the nineteen forties, due to the economic and social reasons, such as the China machinery industry, stagnation, in the 100 years is western bourgeois political revolution and industrial revolution, mechanical science and technology is developing rapidly, and far more than the level of China. So, China mechanical development level and the western gap widens, sharply to the 19th century middle behind western one hundred years. After the founding of new China, especially in the past 30 years, our countrys mechanical science and technology development speed. To the mechanical product large-scale, precision, automation and discusses the trend of development. In some aspects has reached or exceeded the world advanced level. Generally speaking, currently China mechanical science and technology achievement is huge, developing fast, high level of unprecedented. In this period, China has no end of mechanical science and technology will develop to a higher level. As long as we can adopt the correct policy, with good technology development and innovation, our machinery industry and mechanical technology can revitalize, leading to the development trend of mechanical industry. ( 1) Just small ramming machinery: In the 1960s, China mechanical very small tamp lack, many small venues ramming basically USES artificial ramming. Early 1960s, changsha construction machinery institute and Beijing architectural engineering institute, etc., the technical innovation achievements in mass on the basis of summing up Chinese characteristic invented the breaststroke ramming machine, 1962 exceeded 3 national science and technology. The breaststroke ramming machine structure is simple, easy to use and maintenance in 1960s, soon became the dominant products to consolidate machinery. According to not complete count breaststroke tamp cumulative yield reached more than 50,000 machine, in the economic development of our country has played an important role. Since 1970s, the breaststroke ramming machine was gradually more advanced performance of vibration shock ram and vibrating plate ram, now replaced by laying machine has rarely breaststroke, basically be eliminated. In 1964, changsha construction machinery institute HB120 developed movable type, type of Shanghai began laying machine, engineering machine production mainly by Tianjin municipal later, annual production engineering machinery dongting about 200. In the 1980s, movable type ramming machine product quality has increased greatly, have exported to southeast Asia and Africa. Since 1990s, internal-combustion type ramming machine production sales, and gradually decreased in only a few small private enterprise production. In 1977, changsha construction machinery factory buildings and developed in liuzhou HZR250 type and the HZR70 type vibrating plate ram, these two kinds of products in 1979 and 1982 passed by the ministry of construction of the organization. Then yiwu building construction machinery factory, siping, anyang vibrators factory, Tianjin municipal engineering machinery dongting and other enterprises have started producing vibrating plate ram. In 1986, Changsha construction machinery research and develop a larger HZR450 type of vibrating plate ram. Since 1990s, vibrating plate ram in our country has developed very quickly, varieties of products, specifications and increase production enterprises, foreign vibrating plate ram gradually to enter the Chinese market. In 1983, Changsha construction machinery institute and the joint development of Hubei vibration in the first HZR70 type vibration shock ramming, 1984, passed by the ministry of construction, organization construction technology progress in 1985 won prizes. Due to the vibration impact compaction result has good ramming, productivity, high volume and weight of small, lightweight flexible outstanding characteristics, deeply user etc, obtained a rapid promotion, and soon ZiJiang development to the factory, Xinxiang municipal engineering machine tool plant and Tianjin dozens of dongting production factory etc. Vibration shock ramming although than vibrating plate ram, but later development speed of development, 4 production and use of extensive than vibrating plate ram, has become the largest in China in the ramming machinery products. Since 1990s, foreign vibrating plate ram gradually to enter the Chinese market. Vibration shock ramming and vibrating plate ram the successful development in our country, not only for our construction department provides advanced performance of mechanical, laying have achieved good economic benefit and social benefit, and make our ramming mechanical technology into a big step forward, shorten the gap with the advanced world level, promoting the development of compaction machine. ( 2) The mechanical processing: According to the archaeological discovery, hot-working casting in Beijing pinggu, changping and so have proved that the 16th century BC shang dynasty (bronze objects. Ming yongle (1403-1424 years), Beijing produce world-renowned Ming yongle great 3-ton bell made (46.5 tons) and tower (63 tons ) of great 3-ton bells made of iron clock (25) and the furnace of melting, pit TaoFan model and method of casting. In the 1950s, Beijing based on clay sand castings in manual. In 1955, Beijing first machine tool plant began using leakage mould modeling, double-sided model and iron plate type plate and standard sand box modeling. In 1965, start using plastic model.
