FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and can be used to straighten products by compression. Support secured on the base accommodates lower bearing deforming elements with radial travel limiters. Said base supports lower pair of wedge elements coupled with upper pair of the line elements via wedge-like pushers. Said pair of wedge elements incorporate adjustable travel limiters. Aforesaid crosspiece inner side is coupled with upper pair of wedge elements and spring-loaded pusher arranged above upper deforming elements. Crosspiece outer side is coupled with drive chuck. Note that upper deforming elements and lower support elements represent prisms that have at least three consecutively arranged axially symmetric ledges.
EFFECT: compact design, ease of use.
