Abstract
Сущность: в зазор между эластичным пуансоном 7 и стенками матрицы 4 засыпают порошок 8, который покрывает и пуансон 7. Пресс-формы подают в зону прессовани и в матрицу 4 на порошок 8 опускают жесткий пуансон 10, который через проставки 11 перемещает матрицу 4 вниз по колонкам 2, сжима пружины 3. Пуансон 7 раздаетс в горизонтальном направлении, прессу изделие 9. Затем включаютс цилиндры F (ход вверх), прижимают выталкиватель 6 к нижней кромке издели 9, При сбросе рабочего давлени матрица 4 под действием усили пружин 3 поднимаетс , увлека изделие 9. После разгрузки пружин 3 матрица 4 останавливаетс , а выталкиватель 6 продолжает воздействовать на изделие 9 снизу, выталкива его из матрицы 4 вслед за жестким пуансоном ТО. В конце хода выталкиватель 6 своей верхней кромкой достигает верхт матрицы 4 и изделие 9 удал етс с пресс- формы. 1 з.п. ф-лы, 1 ил.Essence: in the gap between the elastic punch 7 and the walls of the matrix 4, the powder 8 is poured, which covers the punch 7. The molds are fed into the pressing zone and the hard punch 10 is lowered into the matrix 4 on the powder 8, which moves the matrix 4 down through the spacers 11 columns 2, compression of the spring 3. The punch 7 is distributed horizontally, the product 9 is turned on. Then the cylinders F (go up) are turned on, the ejector 6 is pressed to the lower edge of the article 9. When the working pressure is released, the matrix 4 rises under the action of the springs 3, carried away and Delije 9. After unloading the springs 3 mold 4 is stopped and pusher 6 continues to be exerted on the product 9 from the bottom, ejecting it from the die 4 after the rigid punch TR. At the end of the stroke, the ejector 6 reaches the top of the die 4 with its upper edge and the article 9 is removed from the mold. 1 s.p. f-ly, 1 ill.
