The invention pertains to a screw press having a flywheel rotationally linked to the spindle by means of a friction coupling and a spindle displaceable axially in a nut mounted within the higher cross member of the press frame, wherein the flywheel has external toothing to a width comparable to the utmost press stroke plus the width of the driving pinion, a plurality of pinions engaging within the mentioned 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 higher cross member of the press frame. three, traces forty and forty one are consultant of the screw stroke, and contours 30, 31, 31′, 33, 34, 35, 36 and forty three are representative of the stroke of beam three. In a high position 30 the beam three is supported by the pistons 9 and 9′ in opposition to the adjustable plunger heads 6″ and 6′” of the pistons 6 and 6′. The power of the pistons 9 and 9′ is such that it exceeds the load of the beam three and the force of the pistons 5 and 5′. This new structure is based on the refractory forming characters, which is our company developed primarily based on SD20 Sequence Electrical Screw Press for the refractory business. Shortly earlier than the end of the downward stroke of the spindle 9 the rotational speed of the pump 27 and hence the rotational speed of the flywheel 17 and the spindle 9 are reduced to zero during the remainder of the stroke of the spindle 9. When the rotational pace is decreased the four-way valve 41 is displaced from the remainder position to the right and the road 42a is related to a second strain-limiting valve forty three. The stress which may be regulated by the strain-limiting valve forty three limits, by the use of the pressure-limiting valve 42, the pressure current within the pipeline 31 to the braking pressure required for braking the flywheel 17. Concerning the current urgent machines, the number of strokes achieved between the washing phases of the moulds, is from 2 to 3 times as great. Since the electric motors are twice accelerated from relaxation to the required rotational velocity and braked once more throughout each working cycle, correspondingly excessive present warmth losses are unavoidable and in addition the idle energy absorbed by the motor is disadvantageous. Experimentally, with a urgent machine in accordance with the present invention, it might be observed that the necessary energy for the first pressing operation, with predetermined plenty of ceramic, will be fairly low, approximately 10-12,000 kg., against the four hundred,000 Kg of the second urgent operations, which is kind of completely different from the current urgent machines, which require about 50 to one hundred fifty tons for the first pressing step.
