The machinery industry is an important part of the equipment industry, and it is also an important basic, strategic and pillar industry in China. Its production capacity directly determines the level of the entire manufacturing industry. In 2011, the machinery industry introduced, digested and absorbed foreign advanced technology. Technology support business. Innovation and solving key technical problems have greatly enhanced the ability of independent innovation.
Combined with the needs of major project construction and the development of key industries, China's machinery industry has developed many important technical equipment with independent intellectual property rights: metal forming hydraulic presses, superplastic high temperature forming hydraulic presses, and speeding up the technological process. Independent production. The main technical equipment has greatly improved the national economic bearing capacity of the equipment.
Cold-formed steel machinery originated in the 1950s and 1960s and was mainly used in agricultural machinery. By the 1980s, the manufacturer had expanded to East China, North China, Northeast China and other regions, but only limited to small and medium-sized L-shaped cold bending machines, with fewer varieties and specifications, about 2,000. The material is ordinary carbon steel, and the total output of cold-formed steel accounts for about 1-1.5% of the total output. Steel, far from the steel of the rest of the world.
The types and specifications of foreign cold-formed steel are generally 8000-10000, and the types of materials are also various. Alloy steel accounts for 50-70%, of which cold-formed steel accounts for 5% of the total output. With the rapid development of the steel industry, the supply is also increasing. The number of cold forming machines has been greatly increased. Users are increasingly recognizing the advantages of cold-formed steel forming machines. It is a cost-effective steel, which can save 15-30% of metal, low investment, flexible production, and can meet various requirements of users. It shows unique advantages in the development of personalized market.
It is expected that the development direction of the cold-formed steel mill in the future will be to improve the mold and equipment, improve the material properties, study the position of the center axis of the rolling mill, improve product standards and product design, bending and materials. deformation. more and more abundant. I believe that with the development of the industry, the era of a single product of cold-formed steel machines will disappear forever. According to this situation, the cold bending machine will tend to be more flexible in design, but the design of a highly flexible cold bending machine will also become a problem for the cold bending machine. It is expected that with the development of modern science and technology, China's cold bending equipment will become more and more advanced.
