SU1419809A1 - Apparatus for hydrostatic compaction of articles from powder - Google Patents

Abstract

The invention relates to powder metallurgy. The purpose of the invention is to expand the production of long products. On the bottom 2 with the rods 8, the required number of blocks consisting of sections 7 and 8 is accumulated, the powder is loaded and it is vibrated on the shaker table. Then install the elastic cover 4 and about

After the cover A is installed and the container is vacuumed, the container is placed into chamber 1, and hydrostatic pressing is performed. The use of a liiji-H device in a hoo-hth connection has made it possible to EXCLUDE what it is. not filled with material and themes. max} is 1g by 1: 1 o for the working space of the hydrostat, and also to simplify the operation of extracting I UToBbK EQUIPMENT from the shell, il.

The invention relates to gyroschec1,; th metallurgy, in particular, to devices for hydrostatic pressing of large-sized products. from poropgkov in vacuum,

The purpose of the invention of pactUHpetuie; - - nologicheskogo opportunities for the device due to half length products.
