Abstract

"DISPOSITIVO PARA FORMAR ARTIGOS TUBULARES DEMATERIAL EM Pó". A presente invenção se refere a umdispositivo para formar artigos tubulares (10) de material em pó (5)compreendendo um punção de prensagem superior (6), um punçãoinferior (3), um pino de núcleo (1) e uma matriz (2) tendo umaperiferia interna que corresponde à periferia externa do punçãosuperior e inferior, uma cavidade de moldagem (4) sendo definidaentre o punção superior e inferior, o pino de núcleo e a matriz, peloque o pino de núcleo é móvel em relação à matriz. De acordo coma invenção o punção de prensagem superior (6) é disposto paraatuar o movimento do pino de núcleo (1) ou da matriz (2), durante acompactação de um pó (5) na cavidade de moldagem (4), de modoque o punção de prensagem e o pino de núcleo ou a matriz semovam juntos.
