METHOD OF MAKING COMPLEX-SHAPE PARTS BY ROTATION DRAWING Russian patent published in 1997 - IPC

Abstract RU 2086330 C1

FIELD: rotation drawing of preliminarily heated parts of hard-to-form metals and alloys. SUBSTANCE: method comprises steps of setting blank on rotating mandrel, moving tool relative to mandrel, rolling out blank at moving tool and changing its inclination angle relative to mandrel axis. Preliminarily heated blank is subjected to deforming. Relative tool motion is realized at motion of mandrel along axis. Angle between tool rotation axis and mandrel axis is decreased at deforming process. EFFECT: simplified process of deforming blanks of hard-to-form metals and alloys. 2 dwg
