FIELD: metal processing.
SUBSTANCE: invention relates to metal forming and can be used in radial forging of hexagonal hollow profiles. Round hollow workpiece is subjected to reduction simultaneously with two mutually perpendicular pairs of strikers in not less than three passes. Strikers of one pair have smooth working surface. Strikers of second pair have cutout grooves with surfaces inclined to each other at an angle of 120°. Working surfaces of mutually perpendicular strikers are offset relative to each other along forging axis by a value exceeding length of working surface of striker. After each pass, workpiece is turned about forging axis through an angle which is a multiple of 60°, to change faces hexagonal hollow profile pressed by pairs of strikers.
EFFECT: higher quality of hollow profiles.
