Ceramic-powder and/or metal-powder press tool, ceramic-powder and/or metal-powder press, modular system with such a press tool, method for assembling and operating a ceramic-powder and/or metal-powder press tool or a press

摘要

The invention relates, in particular, to a ceramic-powder and/or metal-powder press tool, comprising at least one base body (21), a plurality of at least two punches (22-25) which, in a press position, are arranged to be insertable from one side into a die cavity (3) of a die (2) filled with ceramic and/or metal powder (P), a plurality of at least two punch carriers (26-29) each for the attachment of one of the punches, wherein at least part of the die carriers (28;29) is couplable to at least two adjustment drives (39-42) and wherein the punch carriers are arranged to be adjustable relative to each other and relative to the base body, and positive-stop devices (48°, 49, 50) arranged to divert at least part of a pressing force (Fp) from the punches via the base body in a press end position, wherein at least one of the punch carriers is coupled to or mounted on at least two coupling rods (30-33) and each of the coupling rods is couplable to or mountable on its own such adjustment drive. Electromotive adjustment drives are particularly preferred.
