TURRET PRESS Russian patent published in 1995 - IPC

FIELD: manufacture of building materials. SUBSTANCE: molding drum with press-molds and the mechanism for positioning the latter are mounted on the axle, on the press bedplate. The press-molds of the molding drum are made through. The drum itself is set up in bearings on the stationary axis. In its middle part the axis has an eccentric in the form of a disk on which a movable ring is erected. Punches additionally mounted in the press-molds are hinged with the movable ring. The hinged connection allows the punches to shift along the arc of the hinge arrangement on the ring relative to the latter. The mechanism for positioning consists of the pressing disk on the hub, chain gear and resilient member. The driving fingers passing through the holes in the slave sprocket and introduced into the holes on the face end of the molding drum are mounted on one side of the disk. Cams are fastened at different radius on the other side of the pressing disk. Similar cams are fastened on the inner side of the bedplate. The force closure of the cams is carried out by the resilient member located on the exterior side of the bedplate. With one of its ends the resilient member leans against the bedplate, with the other one it acts on the thrust washer. Thrusts passing through the holes in the bedplate and connected with the hub of the pressing disk are fastened on the thrust washer. EFFECT: enhanced efficiency. 2 dwg
