FIELD: technological processes.
SUBSTANCE: invention relates to the field of forging and pressing equipment and can be used for processing workpieces from shaped pipes before their flexible in the manufacture of forged products with a variable cross-section along the length. At least a pair of horizontal straightening rollers and a pair of vertical straightening rollers are fixed on the frame on the shafts. Each roller is arranged in adjusting bracket with handle to change clearance between horizontal straightening rollers at re-adjustment to another standard size of pipes.
EFFECT: enlarging technological capabilities of the device due to providing processing of pipes of various standard sizes.
