METHOD FOR MAKING C-SHAPED BENT SECTION Russian patent published in 1998 - IPC

Abstract RU 2118213 C1

FIELD: rolled stock production, namely manufacture of rolled bent bars of predetermined configuration. SUBSTANCE: method for making C-shaped bent section of zinc plated steel with thickness 0.5-1 mm includes steps of successively bending up strip blank by predetermined bending radius equal to R₁ - between bead and flange and R₂ - between back edge and flange at forming corrugations; sustaining predetermined distance between centers of circles with radius R₁,R₂ and constant radius values in all passes due to metal transition from edge portions of strip to bending zone. EFFECT: enlarged manufacturing possibilities due to possibility of making high quality bent sections from thin coated steel blank. 1 dwg
