FIELD: deep drawing of sheet pieces of work. SUBSTANCE: during power stroke of drawing male die collar of piece of work is preliminarily flattened and corrugated by imparting reciprocating (pulse) motions to clamp. Piece of work is preliminarily bent into П-shaped section chute, lines of bending are directed in parallel with major axis of piece of work. In drawing corrugated portions of piece of work adjoining short sides of sections of piece of work as viewed in plan are flattened by unidirectional flattening effort along axis of piece of work. Simultaneously vertical portions of collar of piece of work are flattened by counter directed flattening efforts perpendicularly to axis of piece of work. EFFECT: enhanced operating reliability. 5 dwg
