Line forty one illustrates the return of the screw, which must be thrown in an up movement with a power of much less value than that supplied for the elastic return of the construction of the pressing machine. The stress exerted by the screw 7′ on the fabric could also be predetermined in a precise method, with the opportunity of utilizing limited torque mills for the stroke of the flywheel, reminiscent of hydraulic motors, electrical motors or friction motors with restricted torque relatively to the motor used as much as this moment. During the acceleration phases for the downward motion and the upward movement of the spindle 9 the electric motor 28 operates with approximately fixed energy and fixed rotational velocity which ensures a high degree of electrical efficiency of the motor 28. The constant motor energy is transformed and fully utilized by the oil pump 27 operating as a torque converter. Stated circuit additional comprising management means for controlling the pressure of the hydraulic fluid fed to mentioned motor means and a plurality of strain phases, one of mentioned phases being controllable as braking strain for said flywheel, and a refill pump means for returning leaked hydraulic fluid to said circuit.
In such a way, the force applied to the mass to be pressed during the phase 36 could differ, from zero (instantly raising the moulds concerning the mass) up to the worth given by the weight of the beam plus the pistons 5 and 5′, with out interruption. Refractory Brick Screw Press Introduction Refractory screw press is a sort of press machine in which the ram is driven up and down by a screw,which have some great benefits of small quantity,short of transmission chain,simple operation. Producer of Disc Friction Screw press machine utilized in manufacturing clay tiles, refractory bricks, Clay bricks and many others. Our Friction Screw Press might be obtainable in various custom-made choices. The line 35 (level 38) represents the equilibrium level between the full pressure utilized by the burden of the beam plus the action of the pistons 5 and 5′, plus the action of the pistons 2 and 2′, minus the motion of the pistons 13 and 13′ but solely with regulations at a passable level (and, in case of utilization of the mirror kind mould, the facility of the pistons sixteen”). The main company in China having been specialised in manufacturing forging hydraulic press,forging manipulator,ring rolling mill,cross wedge rolling mill,electric energy press,friction screw press,etc for over a few years. On this step, consequently, an awesome portion of the kinetic powerimpressed on the flywheel was lost.

For the effect of the kinetic power gathered on the flywheel 2″ through the stroke and which is discharged in the intervening time of contact with the prepressed and already with out air mass, the level 39 develops a powerful instantaneous strain, with a duration of, approximately, thirty-five thousandths of a second. three. A flywheel and screw press based on claim 1, wherein stated flywheel and screw are movable from an higher place and a lower place, the latter being the place wherein the second compacting step is carried out, the space from the higher and the decrease position being such that the flywheel and the screw should rotate at about a flip for transferring from one to the opposite position. Since our inception, we are engaged in manufacturing a complicated array of Friction Screw Press, that are designed to be dependable, environment friendly and exact for Hot Forging of Metal, Brass, Aluminium to our esteemed clients.
The invention relates 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, wherein the flywheel has exterior toothing to a width comparable to the maximum press stroke plus the width of the driving pinion, a plurality of pinions engaging within the mentioned toothed rim are every 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, lines forty and 41 are representative of the screw stroke, and features 30, 31, 31′, 33, 34, 35, 36 and 43 are representative of the stroke of beam 3. In a high place 30 the beam 3 is supported by the pistons 9 and 9′ towards 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 3 and the power of the pistons 5 and 5′. This new construction relies on the refractory forming characters, which is our company developed primarily based on SD20 Collection Electrical Screw Press for the refractory business. Shortly before the top of the downward stroke of the spindle 9 the rotational pace of the pump 27 and therefore the rotational velocity of the flywheel 17 and the spindle 9 are reduced to zero throughout the remainder of the stroke of the spindle 9. When the rotational velocity is decreased the 4-approach valve 41 is displaced from the remainder position to the best and the line 42a is connected to a second pressure-limiting valve forty three. The stress which may be regulated by the strain-limiting valve 43 limits, by way of the stress-limiting valve 42, the strain current within the pipeline 31 to the braking pressure required for braking the flywheel 17. Relating to the current pressing machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to 3 occasions as great. Because the electrical motors are twice accelerated from rest to the required rotational pace and braked again throughout every operating cycle, correspondingly high current warmth 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 noticed that the mandatory energy for the first pressing operation, with predetermined masses of ceramic, will be fairly low, roughly 10-12,000 kg., towards the four hundred,000 Kg of the second pressing operations, which is sort of different from the current pressing machines, which require about 50 to a hundred and fifty tons for the primary urgent step.
