Abstract:
A tool arrangement for the manufacture of ring-shaped compacts using a rotary compression press wherein the rotary compression press has a rotatably driven die-plate (10) having die holes in which die inserts (18) are mounted, and upper and lower rams (12, 14) aligned towards the die inserts (18) and rotating together therewith, which are moved by control portions towards each other and away from each other and wherein the lower ram (14) has a coaxial bore open to the operating end in which a central pin (32) is disposed which is axially located relative to the die-plate (10) by a transverse pin (34 wherein the transverse pin (34) extends through an axial slot of the lower ram (14), characterized in that the transverse pin (34) is located in a ring (36) which forms part of a guide bore (38) for the lower ram (14) which is formed in a radially outwardly facing projection (24) of the die-plate (10), two bracket-shaped retaining clips (44) are disposed on opposed sides of the lower ram (14), wherein said retaining clips having a long leg (46) abuts against the underside of the ring (36) and a short, second leg (48) is bent over the projection (24), a web (50) interconnecting the legs (46, 48) is adapted to be connected to the projection (24) via a bolted joint (52), the retaining clips (44) and the die-plate (10) being formed in such a way that the long leg (46), while the bolted joint (52) is being tightened, is axially pressed against the ring (36) towards the die (16).
