FIELD: technological processes.
SUBSTANCE: invention relates to metal forming, particularly, to straightening of rolled products. Triangular movable stop is installed in outlet part of horizontal roller straightening machine, longitudinal axis of which is located perpendicular to longitudinal axis of horizontal straightening machine. Between right machines on frame there arranged is device for straightening of front end of rail with drive, which includes movable correct roller installed on two bearing supports, which are fixed by means of two connecting rods on crank of crank-and-rod mechanism, worm reduction gear with electric motor is installed on horizontal axis of said mechanism. At that, maximum value of crank-rod gearing is set, equal to maximum deviation of front end of rail along vertical line, distance between longitudinal axis of movable stop and vertical axis of regular roller, and between front end part of rail and first roller there is a process gap.
EFFECT: quality of straightening of rolled stock is provided due to straightening of front end section of rail.
