  • Patent number: 7229263
    Abstract: The present teachings describe various aspects of a pressing device for manufacturing of shaped compacts from pulverized or granulated material. In one aspect, the pressing device includes a frame structure, which, via a lower connection device adapter-like, can be connected to a lower press frame means of a press and a die holding plate arranged in the frame structure. Moreover, the pressing device may further include a base body arranged within the frame structure, the die holding plate, and the base body being arranged in the frame structure relatively movable one to each other, a plurality of punch carriers, at least one part of them being mounted on the frame structure being movable in press direction relatively to the die holding plate and relatively to the base body, and supporting devices which support the punch carriers relative to the base body in the final press position.

  • Patent number: 6902698
    Abstract: A press apparatus for producing dimensionally accurate pressed articles from a particulate material including a frame (70, 73), which can be connected via respective lower and upper connecting devices (71, 72) to a lower and upper platens of a press, a die holding plate (5) arranged in the frame and preferably rigidly connected with the lower connecting device, in which the die holding plate is displaceable relative to a base body (0), a plurality of punch carriers (1-4), at least one of which is supported on the frame between the die holding plate and the base body so as to be displaceable relative thereto into charging and pressing positions by piston/cylinder drives, and supports (12, 22, 32, 42), which in the final press position support the punch carriers relative to the base body.
