Abstract
FIELD: metal pressure forming. SUBSTANCE: method comprises steps of reshaping, a non-round cross section blank to a round cross section one, then performing its preliminary and final drawing. The round cross section blank, been shaped, has a diameter, being by 1-3% less, than a diameter of a design blank. A height of the hollow article, had been subjected to the preliminary drawing process, consists 0.7-0.85 of a height of the ready article. The final drawing process is being performed with thinning of a wall and a head part of the blank end portion on its circular zone, having width equal to 0.65-0.8 of the wall thickness. EFFECT: enhanced quality of articles. 1 cl, 3 dwg
