Abstract
Изобретение относитс к порошковой металлургии, в частности к пресс-формам дл прессовани порошков. Цель изобретени - повышение качества изделий. Пресс- форма содержит матрицу 1, установленную на подкладном кольце 3, на торце которого установлена в полости матрицы 1 упруга прокладка 4. Над пуансоном 9 с отверсти ми под стержни 7 установлена плита 6 с укрепленными в ней стержн ми 7. Торцы стержней 7 выполнены коническими с углом при вершине а 180°-2 Д угол межчастичного трени прессуемого порошка. Во врем прессовани стержни 7 проход т через прессуемый порошок до контакта с упругой прокладкой 4. Выпрессовка осуществл етс за два этапа: на первом - освобождение прессовки от.матрицы, на втором - извлечение стержней 7 из прессовки 10. 1 з.п. ф-лы, 4 ил.The invention relates to powder metallurgy, in particular to molds for pressing powders. The purpose of the invention is to improve the quality of products. The mold contains a matrix 1 mounted on a backing ring 3, on the end of which there is an elastic strip 4 installed in the cavity of the matrix 1. A plate 6 is installed above the punch 9 with holes for the rods 7 and the rods 7 are fixed in it. with a corner at apex a 180 ° -2 D, the angle of the interparticle friction of the pressed powder. During pressing, the rods 7 pass through the powder to be pressed before contact with the elastic gasket 4. The pressing is carried out in two stages: the first is the release of the pressing from the matrix, the second is the removal of the rods 7 from the pressing 10. 1 c.p. f-ly, 4 ill.
