FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and can be used in fabricating bent and stepped axle from hollow square- or rectangular section, or tubular billets, or rube billets wit round cross section or that with 2nd-order curve. One or several billets arranged in parallel are used. Said billets are placed in plastic filler to make a block to be fitted in die half-lower dies so that block or its extreme billets stay in contact with said half-lower die walls. Billet inner cavity or cavities of billets are filled with filler. Said cavities are sealed by punches and stamped via creating filler high hydrostatic pressure an displacing billet extreme parts in direction perpendicular to their initial axes.
EFFECT: reduced power losses and consumed power, higher efficiency and simplified design.
