Cold bending machinery manufacture in China starts late, just get faster development in the 80 s. In general, cold bending profiles production of private enterprises, small and scattered, less varieties of cold bending profiles. Cold bending device in the early days is given priority to with imported equipment, developed by the domestic technical personnel after increases year by year. Past a long time in cold bending equipment in our country have no great breakthrough in technology and manufacturing, investigate its reason lies in the production of rich experience is not enough. But as the time and the rapid development of science and technology, many engineering software is developed, cold bending equipment in material molding has also had the new development direction. Our country had been in the history of cold bending steel plate strip production is low, slow development because of lack of raw materials, with the great development of China's iron and steel industry in recent years, strip production also increased significantly, the deep processing, especially for cold bending steel will be a great opportunity, along with our country iron and steel industry and steel structure to accelerate the development of related industries, such as the demand of cold bending steel is becoming more and more big, cold bending section steel in our country is facing a new development climax.
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 bending mechanical 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.
Cold bending machine is with its exceptional functions as it comes to occupy the domestic market, most of its variety, for some hot rolling method to produce uniform wall thickness, section shape of complex various materials and various material of cold bending steel he can easily deal with, production products high degree of finish, exquisite appearance, size conform to the requirements of the customers. The usefulness of cold bend forming machine is very broad, from simple shelf to B column with get cluttered window. Domestic cold bending machinery industry resources should be integrated, to cooperate, and stronger, bigger, cultivate a world-class Chinese brands; To participate in the international manufacturers cooperation and merger and acquisition; To further realize the internationalization of professional division of labor, actively participate in production of the multinational enterprise group and the subcontract manufacturing; To strengthen enterprise information technology and e-commerce application, to include enterprise resource in the world industrial chain and supply chain. Experts predict that in the next five years China cold bending machinery industry will catch up with and even surpass Japan's production, the pattern of the international cold bending machinery market must shift will occur.
