FIELD: metallurgy.
SUBSTANCE: die consists of drawing channel with deforming zones created with big and small facets. Angle of tilt of the smaller facet to lengthwise axis of the channel exceeds angle of tilt of the bigger facet to lengthwise axis of channel so, that length of a squeezing section of the deforming zone of the bigger facet exceeds length of the squeezing section of the deforming zone of the smaller facet.
EFFECT: increased durability of die, raised stability of process of drawing strip bars out of hard deformed alloys, improved quality of their surface.
