Abstract
FIELD: stamping of articles, such as nails with flat, countersunk heads or flat heads with conical neck. SUBSTANCE: die has punch and at least two die halves, each having detachment surface, surface for clamping rod portion of article to be stamped and head forming surface. End part of head forming surface of each die half is arranged on surface positioned at an angle not exceeding 5 deg to plane perpendicular to longitudinal axis of clamping surface. Such construction allows out-of-roundness of head to be reduced or eliminated due to additional resistance to flowing of material in direction perpendicular to die halves detachment surface. EFFECT: improved quality and wider range of produced articles.
