2500 ton press 

In accordance with the invention, there’s provided a flywheel and screw press for producing ceramic articles comprising, in combination, a base having an higher floor, a set head, help means supporting the fixed head in fixed position upwardly spaced from the upper floor of the bottom, a movable beam positioned within the space between the upper surface and the mounted head and being guided on assist means for motion toward and away from the upper surface, mildew means carried by the bottom and supplied with cavities open upwardly for receiving a cost of ceramic powder material, punch means carried by the movable beam and designed to cooperate with the cavities for forming ceramic articles, a first pair of hydraulic piston means carried by the bottom and supplied for imparting an upwardly directed thrust to the movable beam, a second pair of hydraulic piston means carried by the fastened head and provided for imparting a downwardly directed thrust to the movable beam, the first pair and the second pair of hydraulic piston means cooperating for controlling the downward stroke of the movable beam for imparting to the powder in the cavities a gentle precompression causing a primary thickness reduction of the powder mass and an appreciable expulsion of the air enclosed therein, a third pair of hydraulic piston means carried by the fixed head and managed for performing on the movable beam and performing the first compacting step after the gentle precompression, a fourth pair of elastically compressible hydraulic piston means carried by the bottom and supplied with adjustable rod ends and in a position to intrude with the movable beam when the latter is further lowered through the first compacting step for impressing to the movable beam an upwardly directed thrust serving to the elastic return of the compacted powder mass to boost the movable beam instantly after the first compacting step, allowing the expulsion of the remaining air, a flywheel disposed above the fastened head, a screw threadably engaged to the flywheel and carried by the mounted head, motor means supplied for alternatively imparting to the flywheel and the screw rotation in one and in the different course for decreasing and raising the flywheel and screw, and control means for controlling the motor means to function the flywheel and screw within the reducing path in due time for impacting the movable beam and performing a powerful second and ultimate compacting step of the powder material instantly after the elastic return of the powder materials, and hydraulic circuit means for well timed controlling and driving all the pairs of the hydraulic piston means, the hydraulic circuit means interconnecting the entire pairs of the hydraulic piston means.

The invention pertains 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 within the higher cross member of the press frame, wherein the flywheel has exterior toothing to a width corresponding to the maximum press stroke plus the width of the driving pinion, a plurality of pinions partaking in 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 upper cross member of the press body. three, traces forty and 41 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 excessive 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 facility of the pistons 9 and 9′ is such that it exceeds the load of the beam 3 and the force of the pistons 5 and 5′. This new structure is predicated on the refractory forming characters, which is our company developed based on SD20 Sequence Electric Screw Press for the refractory industry. Shortly before the tip 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 during the rest of the stroke of the spindle 9. When the rotational speed is reduced the 4-approach valve forty one is displaced from the remaining position to the right and the line 42a is connected to a second stress-limiting valve forty three. The strain which might be regulated by the strain-limiting valve forty three limits, by means of the stress-limiting valve forty two, the stress current within the pipeline 31 to the braking pressure required for braking the flywheel 17. Regarding the present urgent machines, the number of strokes achieved between the washing phases of the moulds, is from 2 to three occasions as nice. For the reason that electrical motors are twice accelerated from relaxation to the required rotational speed and braked again during every operating cycle, correspondingly excessive present warmth losses are unavoidable and also the idle power absorbed by the motor is disadvantageous. Experimentally, with a pressing machine in accordance with the current invention, it could be observed that the mandatory energy for the primary urgent operation, with predetermined masses of ceramic, could be fairly low, approximately 10-12,000 kg., in opposition to the four hundred,000 Kg of the second pressing operations, which is sort of completely different from the current pressing machines, which require about 50 to a hundred and fifty tons for the first pressing step.

4, by one axial piston motor 26. The axial piston motor 26 is fed by the oil pump 27 which is pushed by the electric motor 28. When the feed course of the pump 27 is reversed there is additionally a change in the course of rotation of the axial piston motor 26 which in a single path of rotation results the downward motion of the spindle 9 for the working stroke and within the other course of rotation results the upward movement of the spindle 9 so as to return to the beginning place. Enterprise Profile : GRD Mechanical Works is one of the main Manufacturer & Provider of All Kinds of Power Press, Friction Screw Press, Forging Press & Equipment Components and plenty of extra. The time for such programs is determinable, by delaying the strain section of the pistons 2 and a pair of’ by the valves fifty five and 56. The flywheel and screw are movable from an higher place and a decrease position, the latter being the position wherein the second compacting step is performed, the house from the upper and the lower place being such that the flywheel and the screw must rotate at a couple of turn for moving from one to the opposite position. It’s part of the enterprise transformation of the scene graph, Disadvantage of Friction Disk Screw Press: Long transmission chain and excessive energy loss. With a view to reduce the structural expenditure and to extend the operational reliability, every axial piston motor or pair of axial piston motors associated with a pinion has associated with it on the platform a controllable pump which is driven by a respective electric motor and is reversible with respect to the move direction. button operation to finish the hearth bricks producing;no radial power.

The step represented by line 31′ is the continuation of the down motion of the beam three after the conclusion of the section 31 of the braking, is the pressing till meeting the equilibrium level between the pressure utilized and the reaction pressure of the mass then pressed (at stage 37). The forging forces do not act on the machine frame but are sustained by the Ram. A pressostat 18 calibrated at 90 atmosphere, energizes a valve 20 which feeds a multiplier 21 taking the required stress to the oil, with this strain being predetermined through a pressostat 19.
