We’re a leading producer, provider & exporter of Press Machine that’s specifically designed by our experienced professionals at our technically advanced infrastructure. The invention relates to a screw press having a flywheel rotationally related to the spindle by means of a friction coupling and a spindle displaceable axially in a nut mounted in the upper cross member of the press frame, wherein the flywheel has external toothing to a width similar to the utmost press stroke plus the width of the driving pinion, a plurality of pinions participating within 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 frame. 3, traces 40 and 41 are consultant of the screw stroke, and lines 30, 31, 31′, 33, 34, 35, 36 and forty three are representative of the stroke of beam 3. In a high place 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 burden of the beam three and the force of the pistons 5 and 5′. This new construction is based on the refractory forming characters, which is our company developed primarily based on SD20 Series Electric 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 therefore the rotational velocity of the flywheel 17 and the spindle 9 are decreased to zero during the rest of the stroke of the spindle 9. When the rotational pace is diminished the four-way valve 41 is displaced from the remainder place to the proper and the road 42a is connected to a second stress-limiting valve forty three. The pressure which may be regulated by the pressure-limiting valve 43 limits, by way of the pressure-limiting valve 42, the pressure current within the pipeline 31 to the braking pressure required for braking the flywheel 17. Regarding the current pressing machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to three times as nice. Because the electrical motors are twice accelerated from rest to the required rotational speed and braked again throughout each working cycle, correspondingly excessive present 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 would be observed that the required power for the primary pressing operation, with predetermined masses of ceramic, could be quite low, approximately 10-12,000 kg., towards the 400,000 Kg of the second urgent operations, which is quite different from the current urgent machines, which require about 50 to 150 tons for the primary urgent step.
