FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used for processing of long ribbed parts. Straightening of said ribbed parts is executed by the part ribs and web squeezing by rollers at calculation of rollers squeezing force and rollers work area depending upon the part flexure in two perpendicular planes and angles of twisting of the part cross-sections. Straightening is performed with the help of the device composed of a set of burnishers with body shaped to clip-like squeezed elements. Said squeezing rollers are fitted at the ends of clips. Note here that one of said rollers is provided with drive shaft while second roller is equipped with micrometric loading mechanism. Note also that moving thrusts are arranged at every clip body to adjust the position of rollers at squeezed element.
EFFECT: higher quality of long ribbed parts.
