METHOD OF SHAPING CYLINDRICAL PARTS Russian patent published in 1995 - IPC

Abstract RU 2043807 C1

FIELD: metal pressure forming. SUBSTANCE: method of shaping thin-wall cylindrical parts from hard-to-deform metals and alloys with α and quasi a-structure comprises steps of placing the cylindrical blank on a rotating mandrel and deforming it by rollers, being moved along its axis with simultaneous continuous local induction heating of it before a deformation zone; setting a temperature of local heating of the blank being by 40-250 C less, than a recrystallization temperature of a metal of the blank. EFFECT: enhanced quality of cylindrical parts from hard-to-deform metals and alloys. 1 cl
