Abstract：

Due to the advantages of low cost and the products with complex cross section, roll-formed parts are widely used in the automotive, furniture, construction and other industries. In recent years, automotive industries are interested in enhancing the lightweight and safety of parts, roll forming process is logical process to be improved as unique advantage of high efficiency and high material utilization. Five advanced roll forming processes were introduced including 3D roll forming, linear flow splitting, tailor roll forming, partially heated roll forming and hot roll forming. The characteristics of gradually forming in roll forming process are used in the former three technologies,which enrich the section shape of cold roll-formed parts, break out the inherent in the concept of roll forming, such as the uniform thickness and the uniform section. The remaining two new roll forming processes directly change the traditional concept that forming at room temperature, expand the application range of high-strength steel in roll forming process.
