摘要: To effectively manufacture three-dimensional sheet metal parts with various curvatures produced in small-batch quantity, a continuous roll forming (CRF) process is proposed and investigated. The compressed between pairs of bended rolls formed into doubly curved surface. shapes the gap two are piecewise controlled at series points. nonuniformly distributed them make bent longitudinal transverse directions simultaneously after passes through gap, surface continuously rotation rolls. relation elongation distribution bending deformation discussed, lateral spreading CRF analyzed; method to compute profiles presented. Forming experiments for torus-shaped were carried out, experiment results demonstrate feasibility validity presented methods.
