On machines employing the Vincent precept, the screw nut is positioned in the top cross head of a frame sort ram. No. three,359,608, the motion of the pistons 2, 2′ and the motion of the screw 7′, is completed by digital means, with the use of temporizer elements, which may be regulated to be able to obtain the shortest potential interval between one and the opposite motion, comparing with the characteristics of the fabric to be pressed. The above-mentioned diameters are good for a urgent machine with a net pressing power of four hundred to 500 tons. Via the hydraulic motor three it’s possible to manage the speed of the flywheel 2″ and, consequently, the urgent force of the screw 7′, for the purpose of compacting.

The invention relates to a screw press having a flywheel rotationally connected 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 akin to the maximum press stroke plus the width of the driving pinion, a plurality of pinions participating within the mentioned 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 along with the pinions are disposed on a platform surrounding the upper cross member of the press body. three, lines 40 and forty one are representative of the screw stroke, and contours 30, 31, 31′, 33, 34, 35, 36 and forty three are consultant of the stroke of beam three. 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 facility of the pistons 9 and 9′ is such that it exceeds the weight 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 firm developed based on SD20 Collection Electric Screw Press for the refractory industry. Shortly earlier than the tip of the downward stroke of the spindle 9 the rotational velocity of the pump 27 and therefore the rotational velocity of the flywheel 17 and the spindle 9 are lowered to zero during the rest of the stroke of the spindle 9. When the rotational speed is diminished the four-way valve 41 is displaced from the rest position to the best and the road 42a is connected to a second stress-limiting valve 43. The stress which will be regulated by the pressure-limiting valve 43 limits, by the use of the stress-limiting valve 42, the strain current in the pipeline 31 to the braking strain 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 3 times as nice. Since the electric motors are twice accelerated from relaxation to the required rotational pace and braked again during every working cycle, correspondingly high current warmth losses are unavoidable and also the idle energy absorbed by the motor is disadvantageous. Experimentally, with a pressing machine in accordance with the present invention, it might be noticed that the necessary energy for the primary pressing operation, with predetermined plenty of ceramic, can be quite low, roughly 10-12,000 kg., against the 400,000 Kg of the second pressing operations, which is quite different from the current urgent machines, which require about 50 to one hundred fifty tons for the first urgent step.
