POWDER COMPACTION DEVICE Russian patent published in 2017 - IPC B29C43/02 B29C43/04 B29C43/30 B22F3/03 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a technique of compression, in particular to a device of bilateral pressing of the powders, but preferably the porous material with a low bulk density, such expanded graphite to obtain a rod, rods of various diameters and a composition comprising a metal sleeve with a sealed therein expanded graphite to obtain electrode. The device for pressing the powders comprises mould forming rods mouthpiece, an array of cylindrical form, mounted with a holder and punch. Additionally, it is provided with a second similar mould. Molds are arranged coaxially and are joined metal rods and the guide sleeve. As the metal sleeve, the conductive tube is used. The holders are made detachable and additionally have cavities of cylindrical shape to contain the matrix, associated with a large base of the cone clips holes. Punches have removable limiters of the cage motion in a direction from the ends to the central portion at an angle and the sleeve, as a device element, is formed with a smooth inner surface.

EFFECT: possibility of obtaining a monolithic conductive product in the form of expanded graphite rod or an electrically conductive composition, which comprises a thermally expanded graphite in a metal shell with a uniform distribution of properties, and increase the adhesive bond between the components of the composition; as well as the expansion of technological capabilities of the device.
