Industry prospect of cold roll forming equipment:

To understand the general situation of the industry, first of all, let's understand the equipment. Today, Xiao Bian introduces the cold roll forming equipment, which is composed of the main looper uncoiler, high-frequency crimping packer, flying saw straightening and other machines. The cold bending forming is a plastic processing process that continuously bends the coiled materials, strips and other metal plates and strips through the multi pass forming rolls configured in sequence to make specific section profiles.

(1) Development overview of global cold bending equipment industry

The cold roll forming equipment is a multi pass forming roll configured in sequence, which can bend the plate laterally, and process high value-added products with good mechanical properties, high dimensional accuracy and high surface quality. Cold roll forming technology is a metal forming process with material saving, energy saving and high efficiency.

Cold bending technology abroad has a history of more than 100 years, which can be roughly divided into three stages.

The first stage (1838-1909) was the exploration and trial production stage, during which the research work on roll forming theory and cold formed section steel progressed slowly. With the rapid development of industrial transportation, the cold formed steel produced by roll forming process can no longer meet the requirements of users.

The second stage (1910-1959) is the stage of establishing and gradually promoting the roll cold bending process.

The third stage (1960 to the present) is the stage of rapid development of roll forming production. At present, the foreign cold bending forming process has been continuously improved, and the commercial software of cold bending CAD is relatively mature, but its price is high, the design process is cumbersome, and the design theory and process are technically locked, which cannot solve the production problems of domestic steel plate manufacturers in a limited way, nor can it completely change the production situation of domestic manufacturers.

(2) Development of cold roll forming machine industry in china

In recent years, with the in-depth study of cold bending forming and number, the main technology and equipment level of cold bending forming in China has entered the advanced ranks, and four roll forming has been produced successively New cold bending forming processes, such as flexible cold bending forming, CAT forming "roll punching" hole processing method, have laid a solid foundation for the rapid development of cold bending steel industry.

As enterprises combine the actual situation of their own factories, through independent research and development, or the introduction of foreign advanced technology, the equipment and technical level of enterprises have been continuously improved, thus improving the technical equipment level of domestic cold bending equipment manufacturers. The continuous improvement of production process and technical capacity has promoted the development of a number of high-speed rolling mills, and large-scale, cost-effective, and intensive development is under way, In order to achieve the goal of producing high-quality products with high efficiency.

With the continuous improvement of technology, it is inevitable to produce the cold check section steel with beautiful appearance, environmental protection and energy conservation, and economic and practical installation convenience. The application of this efficient and economic section steel  is also becoming more and more extensive. 

Development of domestic cold bending profile technology, the domestic cold bending forming equipment industry has made great achievements in the development of process technology products  has good prospects for development.
