Abstract: Flexible roll forming is a new plastic processing technology,compared with the traditional strip forming technology,the process takes the multi-pass forming roll small angle changes to complete the forming requirements,combined with automation and high-level intelligent control system,high technology advanced,the upgrade of the process can better use the frame structure to achieve lightweight. According to the different characteristics of forming members,including equal section,variable section,axis side bending and variable depth members,the research status of roll forming technology was investigated,including the mechanism,forming force and finite element simulation. The types and mechanisms of defects in the process of forming were described,and the improvement measures used to control these defects were given. Finally,the application fields of this process and the key development and application fields in the future were summarized.It was pointed out that this process has a good development prospect in manufacturing high-precision and high-quality components with high automation level.

Key words: roll forming, flexible, profiles, light weight, defect
