SYSTEM OF GAUGES OF PROFILE-BENDING SECTION MILL Russian patent published in 2009 - IPC B21D5/06 

FIELD: mechanics.

SUBSTANCE: invention refers to the tool used for metal deformation process, and namely to rolls and rollers of forming stands of profile-bending mills. Gauge system consists of pairs of horizontal cylinder-conical rolls installed in stands, and pairs of vertical rollers installed after each forming stand of the mill. At that, after the second and third mill stands there installed are rollers with working surfaces formed with two flattened cones, the small diametres of which are attached to each other, after the fifth stand there installed are rollers with working surfaces, each of which is formed with two flattened cones with cylindrical surface between them. After the rest forming stands there installed are vertical rollers with cylindrical surfaces with flattened cones on upper edges of rollers, which contact edges of bent flanges.

EFFECT: improving quality and economic properties of special channels owing to their geometry improvement.
