Double-disk friction screw press is a commonly used friction screw press which is extensively used for compression moulding of die forging, extrusion, scrap minimize, bending, revision and refractory of ferrous and non-ferrous steel.

The invention pertains to a screw press having a flywheel rotationally related to the spindle by the use of a friction coupling and a spindle displaceable axially in a nut mounted within the higher cross member of the press body, wherein the flywheel has external toothing to a width similar to the maximum press stroke plus the width of the driving pinion, a plurality of pinions engaging in the said toothed rim are each pushed 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 body. 3, traces forty and 41 are representative of the screw stroke, and features 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 3 is supported by the pistons 9 and 9′ against the adjustable plunger heads 6″ and 6′” of the pistons 6 and 6′. The ability of the pistons 9 and 9′ is such that it exceeds the weight of the beam three and the pressure of the pistons 5 and 5′. This new construction relies on the refractory forming characters, which is our company developed based on SD20 Collection Electrical Screw Press for the refractory industry. Shortly before the top of the downward stroke of the spindle 9 the rotational pace of the pump 27 and therefore the rotational speed of the flywheel 17 and the spindle 9 are diminished to zero throughout the rest of the stroke of the spindle 9. When the rotational velocity is diminished the 4-way valve forty one is displaced from the remainder place to the right and the road 42a is connected to a second stress-limiting valve 43. The stress which will be regulated by the stress-limiting valve forty three limits, by the use of the strain-limiting valve 42, the strain current in the pipeline 31 to the braking stress required for braking the flywheel 17. Regarding the current urgent machines, the number of strokes achieved between the washing phases of the moulds, is from 2 to 3 occasions as great. Since the electrical motors are twice accelerated from relaxation to the required rotational pace and braked again during every operating cycle, correspondingly high current heat losses are unavoidable and also the idle power absorbed by the motor is disadvantageous. Experimentally, with a urgent machine in accordance with the present invention, it will be observed that the mandatory power for the primary urgent operation, with predetermined masses of ceramic, may be quite low, approximately 10-12,000 kg., against the 400,000 Kg of the second pressing operations, which is quite totally different from the current pressing machines, which require about 50 to 150 tons for the primary pressing step.

Furthermore, the sum of the times inherent to the first and second urgent step impeded discount of the period of an entire compacting cycle; and, the period was always larger than three seconds.
