AUTOMATED LINE FOR MAKING THIN-WALL BENT SHAPES Russian patent published in 2002 - IPC

FIELD: equipment for making thin-wall bent shapes. SUBSTANCE: automated line includes uncoiler, feeding unit, guiding unit, shape bending aggregate, apparatus for cutting off shape; measuring device and electric drive unit with control board; receiving table with knocking out member. In order to realize continuous operation mode of shape bending aggregate and to cut off predetermined length shape, line includes metering device with electronic control circuit. Electric heating furnace is used for shaping low-ductile materials. Shape bending aggregate includes bending-sizing unit for shaping flat blank and sizing shape by tension with use of roller pair and bending shape according to predetermined curvature. All apparatuses are in the form of separate units. In order to shape low- ductile materials, shape bending aggregate has electric furnace for heating rollers of shaping stands. EFFECT: enhanced quality of bent thin-wall shapes due to equalized remaining stresses, enlarged manufacturing possibilities due to heating hard-to-form materials, lowered metal consumption due to decreased number of transition stages. 2 cl, 2 dwg
