METHOD OF SHAPING BICURVED SHEET PARTS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to metal forming, particularly, to production of shells with bicurved convexed surface by methods of serial or rotary-local deformation. Shaping by serial or rotary-local deformation of bicurved sheet parts like spherical, toroidal-spherical and sail-like shells is performed along blank edges toward its gravity centre in helical lines.EFFECT: lower labour input, decreased amount of unavoidable tapering and cold working, hence, higher quality and serviceability of resultant structures.4 dwg
