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.

Формула изобретенияClaim 1. Пресс-форма для прессования металлического порошка, содержащая матрицу, установленную на подкладном кольце, плиту с закрепленными в ней стержнями, пуансон и упругую прокладку, размещенную в полости матрицы с возможностью взаимодействия с торцами стержней, отличающаяся тем, что, с целью повышения качества изделий, пуансон выполнен со сквозными отверстиями под стержни, плита со стержнями размещена над пуансоном, а упругая прокладка установлена на торце подкладного кольца.1. A mold for pressing metal powder, comprising a matrix mounted on a spacer ring, a plate with rods fixed therein, a punch and an elastic gasket placed in the matrix cavity with the possibility of interaction with the ends of the rods, characterized in that, in order to improve quality products, the punch is made with through holes for the rods, the plate with the rods is placed above the punch, and the elastic gasket is installed on the end face of the washer ring. 2. Пресс-форма ποπ.Ι,οτη ичающая с я тем, что торцы стержней выполнены коническими.2. The mold ποπ.Ι, οτη arises from the fact that the ends of the rods are made conical. Фиг.ЗFig.Z ФигЛFigl
