FIELD: mechanical engineering; corrugating of sheet materials.
SUBSTANCE: invention provides bending of sheet blank to form three-dimensional relief structure. Blank is bent and folded to provided complete joining of edges of folded structure block. Then shifting forces are applied to blank in plane of its edges to form arc with radius of curvature in cross section defined by preset design parameters of curvilinear folded structure. Block fixed in said position is subjected to heat treatment under definite conditions to remove inherent stress in material of folded structure. Then block is stretched to preset design parameters.
EFFECT: improved quality of articles, enlarged technological capabilities.
