FIELD: apparatuses for hydrostatic pressing of powder articles such as tubes.
SUBSTANCE: apparatus includes housing with upper and lower stationary cross pieces, movable crosspiece arranged between stationary ones. Central rod is rigidly joined with piston of hydraulic cylinder for moving it and it is secured to movable crosspiece. Over movable crosspiece pressing chamber with upper and lower plugs having central through openings is arranged. Upper plug is forced to chamber by means of screw turned-on to upper crosspiece. Lower plug and cylinder for moving central rod are rigidly mounted on movable crosspiece in such a way that central rod may move in opening of lower plug.
EFFECT: enhanced quality of pressed blanks, lowered loss of material, improved operational reliability and increased useful life period of central rod.
