1. Development of world cold-formed machinery and equipment
The process design of the cold roll forming machine is a roll forming technology for metal profile steel sheets. Compared with other metal forming methods, it can save materials and materials more accurately and ensure the range of error values more precisely.
Through the orderly forming design process, the multi-pass roll forming process can be used for continuous and high-speed horizontal bending of the metal sheet. And it can very accurately control the quality and output efficiency of the formed sheet.
The cold roll forming process has three stages of development:
The first stage (1838-1909) is the exploration and trial production stage. At this stage, the research on rolling and forming theory and cold-formed steel is progressing slowly. With the rapid development of industrial transportation, the cold-formed process can no longer meet the requirements of users.
The second stage (1910-1959) entered a new era of industrialization revolution in the world, which greatly promoted the rapid development of sheet metal cold forming process.
The third stage (from 1960 to the present) is a stage where the cold roll forming machine has a very breakthrough mature process technology. In the stage of comprehensive and efficient development and promotion. At present, foreign cold-formed forming processes continue to improve, and cold-formed CAD commercial software is relatively mature, but the price is relatively high, the design process is complex, and the design theory and process flow are real. The technological blockade cannot solve the production problems of domestic steel plate processing plants in a limited way, nor can it completely change the production conditions of domestic plants.
2. The development of domestic high-end cold roll forming machineindustry
At present, the main technology and equipment level of domestic cold-formed process design have entered the ranks of the global mainstream cold-formed process concept.
It has become a world-class manufacturing plant for the development of the global cold-formed equipment industry. The equipment is exported to Europe, America, South Africa, South Africa, and East Asia. It has established a good market development or process design research and development basis for the rapid development of domestic cold-formed equipment.
The process accuracy and forming speed of cold roll forming machine have been greatly improved, resulting in a new energy-efficient cold-formed forming process. Such as high-efficiency molding methods such as four-roll rapid shaping, flexible cold bending molding, and computer-aided molding.
Domestic cold-formed equipment manufacturers continue to improve the level of technical equipment. According to their own factory conditions, each enterprise continuously improves its equipment level, production technology and technical capabilities through independent research and development or the introduction of foreign advanced equipment.
The future development of cold-formed forming machine process technology requires the development of all aspects of process technology in order to better meet the market needs of various types of steel applications.
Although China's cold-formed equipment manufacturing industry started late, its development has been slow. There are still many shortcomings in this industry. For example, the production of cold-formed steel equipment is dominated by private enterprises, with small scale, scattered distribution, few types of manufactured products, and poor resource sharing.
However, under the strong domestic supply chain supporting system of cold-formed equipment, it has still become the favor of many domestic and foreign cold-formed equipment users, and has gradually made great progress in the process technology and product development of the industry. In the global development prospects of cold-formed equipment, it has the development advantages of sophisticated design, efficient technology, and economical benefits.
