APPARATUS FOR BENDING SHAPES WITH NON-SYMMETRICAL CROSS SECTION Russian patent published in 2000 - IPC

Abstract RU 2148456 C1

FIELD: plastic metal working, namely bending shapes with non-symmetrical cross section. SUBSTANCE: apparatus includes bending punch mounted on rotary table, device for clamping shape on bending punch, rotary draw plate having width variable along it for outer web of shape and designed for passing bent shape. Twisting of cross section non-symmetrical relative to bending plane of shape in direction of its least resistance is eliminated by reverse rotation of draw plate. EFFECT: simplified design of apparatus due to elimination of clamping and tensioning mechanisms allowing to make the same quality bent shapes. 2 cl, 3 dwg
