Description

ют до температуры прессовани , пос- ле чего помещают в глухой штамп (на . чертеже не показан), где производ т его деформацию и прессование порошковой заготовки. Пои этом стержень 4 прошивает мембрану 5 и перемещаетс  в полость 6, на вызыва  нарушени  гер метичности контейнера и обеспечива  высокую точность размеров осевого отверсти  в Спрессованном изделии.После окончани  процесса прессовани  контейнер удал ют механической обработкой, а стержень выпрессовывают из издели .They are pressed to a pressing temperature, after which they are placed in a blank die (not shown in the drawing), where it is deformed and the powder blank is pressed. Therefore, the rod 4 pierces the membrane 5 and moves into the cavity 6, causing the container to leak, and ensuring high dimensional accuracy of the axial bore in the pressed product. After the extrusion process has been completed, the container is removed by machining and the rod is pressed out of the product.

Применение предложенного устройства позвол ет повысить точность разMepOBi осевого отверсти  в издели х из порошков активных металлов и сплаВОВ .The use of the proposed device allows to increase the accuracy once MOBOBi of the axial bore in the articles of powders of active metals and alloys.
