As the cold bending forming equipment constantly improved, cold bending device was gradually known and has been widely used in various fields. Cold bending forming equipment in the domestic market is so open, and to develop rapidly.
Watch the cold bending machine development history, can be traced back to 1950 years or so, then the application of cold bending machine also is not very wide, just has application in agriculture. By around 1980, the cold bending machine in our country just ushered in the first development high tide, the market began to extend from a region to the north east China and other regions, but the specification model is only about 2000 kinds of, while foreign specifications reached about 8000 to 10000, the development scale is very small.
In developing the cold-formed molding equipment, although small, but it also contains the infinite development space. With large iron and steel industry rapid development, the supply of cold bending machine with greatly improved, and gradually replaced the profile of hot rolled profiles and other varieties, is emerging in the market development, exert its unique superior performance. As a result, the steel market in our country, the cold bending forming device has good prospects for development, has huge development platform.
Enterprises should focus on product quality, rather than blindly pursue low cost, otherwise will be eliminated by the market. Cold bending machine product emerge in endlessly, market competition is very fierce, internationally, the price advantage of being very high, many companies are focused on the export business, efficiency is also very good, but did not form scale sales network. But we can't just rely on the advantage of price to occupy the market, the quality is also the important factors influencing the efficiency. Enterprises should focus on product quality, rather than blindly pursue low cost, otherwise will be eliminated by the market.
Along with the development of science and technology in our country and society industry scale, uniform wall thickness, section shape of complex profile and all kinds of different material steel is now more and more been used in all aspects of the society, but the hot rolling of the steel with traditional method is difficult to produce, and with the emergence of cold bending unit processing of cold bending technology well solved this difficult problem.
Finish after cold bending processing of products, appearance, size, etc can all can be adjusted according to the demand, at the same time cold bend section steel production process in the aspect of material can be save, can save metal 15-30%, less investment, flexible production. So cold bend section steel has become an unstoppable trend. It is reported, "11th five-year plan" at the end of the cold bending steel demand will grow to 11.02 million tons, and with the development of China's western development strategy, the western construction of cold bend section steel demand will have faster growth.
