FIELD: plastic working of metals, possibly manufacture of corrugated constructions with wrinkled structure from thin-sheet material.
SUBSTANCE: method comprises steps of feeding continuous blank in the form of linear corrugation to shaping zone; jamming blank for forming in it two jammed zones in the form of mutually spaced saw-tooth lines or saw-tooth belts consisting of rectangular faces; forming on blank zigzag and saw-tooth lines according to marking out lines on development of zigzag corrugated structure. In order to realize it, between jammed zones part portion with zigzag corrugated structure in the form of two-row or three-row belt is formed. Said two-row belt includes two belts with faces in the form of parallelogram. Three-row belt includes two belts with faces in the form of parallelogram and arranged between them mean belt with rectangular faces. At jamming, mean belt of three-row belt is shaped in such a way that to provide its profile similar to that of saw-tooth belts but shifted in cross direction. Shifting value is equal to amplitude of zigzag lines of corrugated structure. All operations are cyclically repeated.
EFFECT: enlarged manufacturing possibilities of method.
