The invention pertains to a screw press having a flywheel rotationally connected to the spindle by way of a friction coupling and a spindle displaceable axially in a nut mounted in the higher cross member of the press frame, whereby the flywheel has exterior toothing to a width akin to the maximum press stroke plus the width of the driving pinion, a plurality of pinions engaging within the said toothed rim are each driven by oil-hydraulic axial piston motors or by a pair of oil-hydraulic axial piston motors and the axial piston motors together with the pinions are disposed on a platform surrounding the upper cross member of the press body. 3, traces 40 and forty one are consultant of the screw stroke, and contours 30, 31, 31′, 33, 34, 35, 36 and 43 are representative of the stroke of beam 3. In a high position 30 the beam three is supported by the pistons 9 and 9′ towards the adjustable plunger heads 6″ and 6′” of the pistons 6 and 6′. The facility of the pistons 9 and 9′ is such that it exceeds the weight of the beam 3 and the force of the pistons 5 and 5′. This new construction is predicated on the refractory forming characters, which is our firm developed based mostly on SD20 Series Electrical Screw Press for the refractory business. Shortly before the tip of the downward stroke of the spindle 9 the rotational pace of the pump 27 and hence the rotational pace of the flywheel 17 and the spindle 9 are diminished to zero during the rest of the stroke of the spindle 9. When the rotational pace is diminished the four-method valve forty one is displaced from the remaining position to the fitting and the road 42a is linked to a second pressure-limiting valve forty three. The pressure which may be regulated by the stress-limiting valve forty three limits, by way of the pressure-limiting valve 42, the pressure present in the pipeline 31 to the braking strain required for braking the flywheel 17. Concerning the present urgent machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to three instances as nice. Since the electrical motors are twice accelerated from relaxation to the required rotational pace and braked again during each operating cycle, correspondingly high present warmth losses are unavoidable and likewise the idle power absorbed by the motor is disadvantageous. Experimentally, with a urgent machine in accordance with the present invention, it would be observed that the necessary power for the first pressing operation, with predetermined masses of ceramic, may be fairly low, roughly 10-12,000 kg., in opposition to the four hundred,000 Kg of the second pressing operations, which is quite completely different from the current pressing machines, which require about 50 to a hundred and fifty tons for the first pressing step.
