FIELD: plastic working of materials.
SUBSTANCE: method comprises steps of deforming blank in vertical and horizontal ducts while moving blank in horizontal duct at applying counter-pressure to it by performing percussion action upon blank in direction opposite relative to blank motion direction. Blank is also subjected to rotation in arbitrary direction. Percussion-rotation actions upon blank in horizontal duct are cyclically repeated. Counter pressure effort and frequency of percussion-rotation action upon blank in horizontal duct are also cyclically repeated.
EFFECT: improved physical-mechanical properties of materials, enhanced quality of blanks, simplified working process.
