FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to metal forming. Drawing of blank is carried out with resilient blank holder and female die adjoining the flange entire surface during the whole process. Said blank holder and female die are composed of metal rings that allow elastic displacements for blank flange to be pressed at required pressure over its entire surface. Note here that female die is fitted at fixed support ring.
EFFECT: higher surface quality and strength, decreased pressure force and higher limiting drawing ratio.
