Abstract
"MéTODO DE COMPACTAçãO DE Pó E DISPOSITIVO DE COMPACTAçãO DE Pó". A presente invenção foi realizada, a fim de se obter materiais compactos crus de uma altura fixa por moldagem por pressão do material em pó com um espaço fixo entre os perfuradores superior e inferior. Um método de compactação de pó dessa invenção realiza uma etapa de acionamento de perfuração na qual, após o material em pó ser colocado em uma cavidade, o material em pó colocado na cavidade é moldado por pressão pela utilização de um perfurador superior e um perfurador inferior, a dita etapa de acionamento de perfurador compreendendo uma etapa de acionamento primário acionando um dos perfuradores até que a espessura da cavidade formada entre os perfuradores superior e inferior se torne ligeiramente maior do que a espessura de moldagem alvo, e uma etapa de acionamento secundária que mede um espaço entre os perfuradores superior e inferior e aciona um dos perfuradores, enquanto controla o mesmo até que o valor medido alcance a espessura de moldagem alvo."DUST COMPACTING METHOD AND DUST COMPACTING DEVICE". The present invention has been realized in order to obtain raw materials of a fixed height by pressure molding the powder material with a fixed space between the upper and lower punches. A powder compaction method of this invention performs a drilling drive step in which, after the powder material is placed in a cavity, the powder material placed in the cavity is pressure molded by using an upper punch and a lower punch. , said punch drive step comprising a primary drive step driving one of the punches until the thickness of the cavity formed between the upper and lower punches becomes slightly greater than the target molding thickness, and a secondary drive step which measures a gap between the upper and lower punches and drives one of the punches while controlling it until the measured value reaches the target molding thickness.
