Friction Screw Press Down Stroke is manufactured utilizing excessive grade chrome steel material which provides it a extremely durable service life. The power utilized to the mass throughout this final phase is given by the burden of the beam three plus the strain of the pistons 5-5′, minus the pressure exerted by the pistons 13 and thirteen’, which is contrary to the prior one, minus the eventual pistons sixteen”.
The invention relates to a screw press having a flywheel rotationally linked to the spindle by the use 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 external toothing to a width similar to the maximum press stroke plus the width of the driving pinion, a plurality of pinions participating in the stated toothed rim are every 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 upper cross member of the press frame. three, strains 40 and forty one are representative of the screw stroke, and contours 30, 31, 31′, 33, 34, 35, 36 and 43 are consultant of the stroke of beam three. In a high place 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 facility 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 structure relies on the refractory forming characters, which is our company developed primarily based on SD20 Collection Electric Screw Press for the refractory trade. Shortly before the top of the downward stroke of the spindle 9 the rotational speed of the pump 27 and therefore the rotational speed 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 pace is reduced the four-method valve 41 is displaced from the remaining place to the suitable and the road 42a is linked to a second stress-limiting valve forty three. The strain which might be regulated by the pressure-limiting valve 43 limits, by way of the strain-limiting valve 42, the pressure current in the pipeline 31 to the braking stress required for braking the flywheel 17. Relating to the present urgent machines, the number of strokes achieved between the washing phases of the moulds, is from 2 to three instances as nice. For the reason that electrical motors are twice accelerated from rest to the required rotational speed and braked once more throughout each working cycle, correspondingly high current heat 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 power for the primary urgent operation, with predetermined lots of ceramic, might be fairly low, roughly 10-12,000 kg., against the 400,000 Kg of the second urgent operations, which is kind of completely different from the current urgent machines, which require about 50 to one hundred fifty tons for the primary pressing step.
Line 43 signifies the extraction of the pressed part by the mould because of the piston commanded by the respective valves 63 and sixty four in synchronism with the beam and the screw in a brand new up motion achieved by known command circuits.

Swap 23 energizes the valve 17 to disconnect the pilot of a examine valve 22 and introduces oil at a strain of one hundred atmospheres into the chambers 15 and 15′ of dynamic oil accumulators 14, 14′ which can be hydraulically connected to pistons 13, thirteen’ as shown in FIGS. The torlence of controlling energy of Electrical Screw Press is 0.2%, and the torlence of influence energy is only 1%. The small quantities of oil working off from the strain-limiting valves forty two and 43 and the 4-way valve forty one during the reversing and likewise as leaked oil are fed again once more into the closed circuit by a pump 45 driven by a motor 44. A spring-centered, stress-managed three-means valve forty six is offered in an effort to ensure the feed pressure required at the pump 27 and controlled by the strain-limiting valve 47. The three-approach valve 46 is actuated in such a way that the respective low-stress aspect of the closed circuit is connected to the stress-limiting valve 47, the feed pressure being maintained by the pump 45. For cleansing and cooling the oil, the oil which has escaped from the circuit, is collected partly 32b of the tank 32, handed on after preliminary cleaning by sedimentation to part 32c of the tank 32, is fed by filters 50 and coolers fifty one by a pump 49 driven by an electrical motor forty eight and is saved in part 32a of the tank 32. Therefore, instead of ending the primary pressing with the value of the urgent, the volume of oil at high strain may be used. The electric screw press is pushed by permanent magnet synchronous servo motor,and include mechanical pats equivalent to framework, flywheel, screw nut, the slider, lubricating mechanism, braking mechanism and electric parts similar to servo motor, electrical control cupboard, operating button station.
4, by one axial piston motor 26. The axial piston motor 26 is fed by the oil pump 27 which is pushed by the electrical motor 28. When the feed route of the pump 27 is reversed there’s also a change in the path of rotation of the axial piston motor 26 which in one direction of rotation results the downward motion of the spindle 9 for the working stroke and in the different direction of rotation effects the upward motion of the spindle 9 in order to return to the beginning position.
