METHOD OF MANUFACTURE OF PRECISION BULB-STRIP NONSYMMETRICAL SECTION Russian patent published in 1997 - IPC

Abstract RU 2080194 C1

FIELD: manufacture of precision bulb-strip nonsymmetrical section including those of small cross-section. SUBSTANCE: combined blank is deformed in common roughing passes into intermediate identical bulb-strip section. Section walls at the outlet of passes are inclined towards each other. Angle of inclination of each wall of section to horizontal axis of pass equals the angle between the common generating line to internal surfaces of bulb member and wall edge and the base of the finished section. Further on, combined blank of intermediate section is deformed in common finishing pass to produce finished identical bulb-strip section. Finished section at the pass outlet are joined by surfaces of bulb members with walls being perpendicular to vertical axis of symmetry of finishing pass. EFFECT: higher efficiency. 5 dwg
