PROFILE BENDING MACHINE Russian patent published in 2010 - IPC B21D5/06 

FIELD: metallurgy.

SUBSTANCE: invention refers to pressure processing of metals, particularly to profile bending machines for forming of sectional formed bars with relatively simple section. Forming machine for angle and channel sections includes a number of mills mounted in sequence on frame at a distance from each other, with gradual forming level reduction in a part of mills starting from the second mill, and a couple of vertical rolls at a defined distance from axial plane of mill rollers at the mill outlet. Axles of lower rollers in first four mills of the machine are mounted higher than similar axle of the fifth mill by a given height. After the 1^st - 4^th mills, vertical rolls are mounted below top of the body mid-length of the lower roller of respective mill.

EFFECT: improved quality of bent profiles due to reduced tensile stress at the edges of tucked-up elements.
