Description

Дл  изготовлени  втулок методами металлокерамики обычно примен ютс  металлические порошки, прессуемые гидравлическим или механическим прессом в металлических прессформах . В случае необходимости изготовить удлиненные втулки трудно получить однородную плотность по длине втулки при одностороннем прессовании; применение же двустороннего прессовани  в значительной степени усложн ет конструкцию прессформ и устройство прессов. Насто щее изобретение имеет целью устранить отмеченные затруднени . Достигаетс  это тем, что длинные втулки, независимо от формы их сечени , изготовл ютс  составными из отдельных колец, сопр гающихс  друг с другом по кривым поверхност м .Metal powders that are pressed by hydraulic or mechanical press in metal molds are commonly used for the manufacture of bushings by the methods of metal ceramics. In case of need to manufacture elongated sleeves it is difficult to obtain a uniform density along the length of the sleeve with one-sided pressing; The use of double-sided pressing greatly complicates the design of the molds and the design of the presses. The present invention aims to eliminate the noted difficulties. This is achieved by the fact that long sleeves, regardless of the shape of their cross-section, are made of composite parts from separate rings that mate with each other along curved surfaces.

На чертеже фиг. 1 изображает разрез прессформы, предназначенной дл  изготовлени  отдельных колец втулок; фиг. 2-отдельное кольцо втулки; фиг. 3-втулку в собранном виде.In FIG. Figure 1 shows a section through a mold for making individual sleeve rings; FIG. 2-separate ring sleeve; FIG. 3-sleeve assembled.

Прессформа дл  прессовани  отдельных звеньев длинной втулки состоит из массивного стального стакана 7 (фиг. 1), имеющего внутриA mold for pressing individual parts of a long sleeve consists of a massive steel cup 7 (Fig. 1), having inside

канал, поперечный размер которого соответствует наружным размерам изготовл емой втулки; нижн   часть стакана / снизу Илмеет съемное дно 2, вставл емое в канал стакана 7 и несущее сердечник 3, имеющий форму сечени  и размеры, соответствующие внутренним размерам и очертанию втулки. На сердечник надеваютс  кольца 4 и 5, причем очертание кольца 4 может быть выполнено в виде граней (фиг. 2) или ограничено с обеих сторон параллельными плоскост ми (фиг. 3), кольцо же 5 долншо иметь одну поверхность, ограниченную горизонтальной плоскостью, а другую-по кривой, соответствующей кривой поверхности кольца 4.a channel whose transverse dimension corresponds to the outer dimensions of the sleeve being manufactured; lower part of the glass / bottom Ilmeet removable bottom 2, inserted into the channel of the glass 7 and carrying the core 3, having the shape of a cross section and dimensions corresponding to the internal dimensions and outline of the sleeve. Rings 4 and 5 are put on the core, and the outline of ring 4 can be made in the form of faces (Fig. 2) or limited on both sides by parallel planes (Fig. 3), while the ring 5 should have one surface bounded by a horizontal plane, and the other is along the curve corresponding to the curve of the surface of the ring 4.

Перед прессованием кольцо 5 укладываетс  на съемное дно 2 прессформы гладкой стороной; на него засыпаетс  порошкообразна  шихта, прикрываема  кольцом 4; прессование производитс  давлением на кольцо 4. Спрессованна  втулка выталкиваетс  из прессформы обычным путем. При выталкивании изготовленной части втулки одновременно выталкиваютс  кольца 4 и 6, которые легка отдел ютс  от втулки. Спрессованные кольцевые части втулки получаBefore pressing, the ring 5 is laid on the removable bottom 2 of the mold with the smooth side; a powdery mixture is covered in it, covered by ring 4; the pressing is done by applying pressure to the ring 4. The pressed sleeve is pushed out of the mold in the usual way. When pushing out the manufactured part of the sleeve, rings 4 and 6 are simultaneously pushed out, which are easily separated from the sleeve. Compressed ring bushings receive
