With higher project demand for cold bending forming steel function, the geometry section of profiles is becoming more and more complicated, and pass design of rolling section steel is becoming more and more difficult. The design method based on experience and estimating doesn't meet the engineering requirements. How to build a stable pass design algorithm, has become the modern pass design difficulties. Although there are many theories studying cold bending forming, those guiding pass design is

... less. The paper is based on spline finite strip theory, studying how to establishing new rolling process model, using linked list model to build Agent structure for each forming stand and transition region, realizing the cold bending forming strain and stress description in a single intelligent stand, founding relationship between forming theory and the parameters of pass design, providing theoretical basis for precision deduction pass design.
