METHOD FOR MAKING PRODUCTS WITH HIGH-CONSISTENCY HOMOGENEOUS STRUCTURE FROM METALLIC, CERMET AND OTHER POWDERS Russian patent published in 2000 - IPC

FIELD: powder metallurgy. SUBSTANCE: method comprises steps of pumping powdered material continuously fed from upwards to shaping cavity of lower die under working surface of rocking pumping member; at each rocking motion approaching working surface and lower die until remaining between them predetermined gap limited by edges of working surfaces of pumping member and lower die; feeding material by height more than gap value and going it on until beginning of displacing part of material out of gap; after starting displacement of powdered material out of gap, moving pumping member along lower die in condition of constant displacement of powdered material out of gap; ceasing feed of material after pumping member descends from shaping cavity of lower die; simultaneously moving safety plate spaced by minimum distance from pumping member along lower die for fixing upper surface of product. In variant of invention lower die is moved under pumping member and safety plate. EFFECT: possibility of making elongated high quality products with high-accuracy of dimensions. 22 cl, 7 dwg
