Abstract
FIELD: metal pressure forming, namely production of sheet cold bent rolled sections. SUBSTANCE: method comprising subsequent (from pass-to-pass) formation of corrugations beginning from mean portion of strip and terminating by strip contact with rolls along its whole width over last pass also comprises steps of eliminating contact of edge portions of strip over all passes except two last passes with upper rolls, removing central large corrugation had been finally formed from contacting with both rolls; beginning formation of small trapezoidal corrugations adjacent with large corrugation simultaneously with formation of steps near root of that corrugation, successively reforming small trapezoidal corrugations to semicircular ones. EFFECT: enlarged manufacturing possibilities of shaping process without lowering quality of corrugated sheets having corrugations of different contour and size and made from chrome-nickel-titanium steel.
