Abstract

FIELD: metals shaping, method is used in mechanical engineering processes of drawing with hollow pieces extension. SUBSTANCE: aim is to increase quality of drawn pieces by prevention of blank breakage in zone of groove formation. Groove is formed as equilateral triangle with height equal to (5 - 7)Sand radius of rounding at groove vertex defined from following equation:, with S- sheet blank thickness;- deformation of sheet material break during its destruction; e - natural logarithm base; ρ- radius of rounding at groove vertex. The form and dimensions of groove allow to avoid blank material breakage in process of drawing. EFFECT: increased quality of drawn pieces by prevention of blank breakage in zone of groove formation. 3 dwg
