LIGHT-TYPE SHAPE BENDING AGGREGATE Russian patent published in 1998 - IPC

FIELD: equipment for plastic metal working, namely production of small-size bent bars. SUBSTANCE: aggregate includes uncoiler, shears, multistand mill, arranged behind mill left and right pockets with end walls for piling ready shaped bars, knocking out member with movable rest mounted on lengthwise ridge beam secured to vertical struts with possibility of rotation in vertical plane clockwise and counter clockwise by 10-20 deg. Beam includes symmetrical cross pieces mounted at predetermined pitch and having lateral branches inclined relative to horizon by angle from 75-80 up to 10-20 deg. First (along profiling direction) cross piece has maximum inclination angle successively decreases in the same direction by 8-10 degrees for each next cross piece. Predetermined-width chute is mounted on said beam along its whole length over said cross pieces. Said chute is arranged under profiling level by value equal to 0.45-0.6 of its width and it is turned upwards by its convex portion whose height is equal to 0.1-9.2 of its width. Pair of horizontal driven rollers may be arranged behind final stand of said mill. EFFECT: enhanced efficiency, lowered labor consumption. 3 cl, 3 dwg
