Abstract

Устройство для формообразования тонкостенных осесимметричных деталей усеченной сужающейся формы, содержащее пуансон, верхний плоский прижим, нижний прижим, матрицу, отличающееся тем, что нижний прижим в средней части имеет цилиндрическую полость, в которой размещен эластичный элемент в виде кольца, наружная поверхность которого выполнена цилиндрической, а внутренняя - конической, причем больший радиус равен радиусу малого торца пуансона, а меньший находится по формуле:,где σ- предел прочности заготовки;S - толщина заготовки;α - угол конусности эластичного элемента;q - давление эластичного элемента;f - коэффициент трения между заготовкой и эластичным элементом;R - радиус большего торца детали.A device for shaping thin-walled axisymmetric parts of a truncated tapering shape, containing a punch, an upper flat clamp, a lower clamp, a matrix, characterized in that the lower clamp in the middle part has a cylindrical cavity in which an elastic element in the form of a ring, the outer surface of which is cylindrical, is placed, and the inner one is conical, with a larger radius equal to the radius of the small end face of the punch, and the smaller one is found by the formula: where σ is the tensile strength of the workpiece; S is the thickness of the workpiece; α is the angle to the cone NOSTA elastic member; q - elastic pressure element; f - coefficient of friction between the workpiece and an elastic member; R - radius of the wide end parts.
