METHOD FOR STRETCHING ELONGATED VARIABLE-SIGN CURVATURE FACINGS AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 1998 - IPC

Abstract RU 2123403 C1

FIELD: plastic metal working, namely forming sheets of elongated facings of double variable-sign curvature. SUBSTANCE: method is realized in stretching press at using controlled flexible shaping members that allow to receive elongated parts of double variable-sign curvature. EFFECT: possibility of making elongated variable-sign facings with concave portions on their ends and lateral surface in simple presses, lowered labour consumption at manufacturing process. 3 cl, 2 dwg
