Description
етс через клапан 8. После окончательной выт жки ступенчатого издели вижением пуансона 1 вверх снимают готовое изделие, давлением жидкости внутрен 1 ю часть 3 матрицы привэд т в исходное крайнее верхнее положение .through the valve 8. After the final stretching of the stepped product, by moving the punch 1, the finished product is lifted up, the fluid pressure of the inner 1 part 3 of the die is brought to its initial extreme upper position.
Наличие жесткого подвижного элемента в матрице устран ет потери устойчивости заготовки на свободной части в процессе формообразовани , пойыиаеТ; точность и качество штам-rfy (5MfcJx изделий.The presence of a rigid rolling element in the matrix eliminates the loss of stability of the workpiece on the free part in the process of shaping, flow T; accuracy and quality of stra-rfy (5MfcJx products.
В экспериментальном устройстве за един переход штамповались ступенчатые детали с фланцем и без фланца со степенью выт жки,равной 2,6-2,9.In the experimental device, step parts with a flange and without a flange with a draw ratio equal to 2.6-2.9 were stamped for a single transition.
