UNCOILER FOR SHAPE BENDING AGGREGATE Russian patent published in 2002 - IPC

FIELD: finishing of rolled strips, particularly equipment for making cold bent rolled bars. SUBSTANCE: uncoiler of shape bending light-type aggregate is designed for coils with predetermined value D of maximum diameter. Uncoiler includes housing in which two side members for aligning coil and supporting rollers are mounted. Novelty is small diameter supporting roller mounted in addition between above mentioned supporting rollers with diameter dp and under lower than level of mounting those rollers. Side members are cross like ones, they have diagonal connecting links. The last (according to rolling process direction) supporting roller is driven one and it has gummed barrel. Linear velocity vector of rotation of said supporting roller in its contact point with coil is opposite to rolling direction. Diameter of supporting rollers dp=(0.08-0.10) D; spacing between their axes l= (0.70-0.75)D. EFFECT: less loss of yield due to lowered labor consumption for making small cross section bent shapes in the result of preventing defects at uncoiling strip. 2 cl, 1 dwg, 1 ex
