METHOD OF MANUFACTURING CURVES Russian patent published in 1995 - IPC

Abstract RU 2036737 C1

FIELD: metal processing. SUBSTANCE: at the first pass semicircular corrugation is shaped simultaneously with flanging turning in. At the second pass this corrugation is reshaped into trapezoidal one with minimal cross extension, giving perimeter increase in 2-8 per cent. At third and consequent passes corrugation is disconnected from lower rolls that excludes crack formation. Bending radius of turned in flanges gradually reduces up to workpiece thickness. Flanges are turned in at radius equal to workpiece thickness. Flanging curve centers are replaced upwards over circle arc regarding flange curve centers. EFFECT: improved design. 1 dwg
