Oil-hydraulic motors, specifically axial piston motors, have a subtantially lower particular weight with small dimensions than electrical motors, so that they are often organized, individually or in pairs, on diametrically reverse a driving pinion, with the further structural benefit that the spindle together with the flywheel and the toothed rim could be mounted axially displaceably in a nut mounted in the upper cross member of the press frame and are thus uncovered solely to torsion above the nut and solely to thrust under the nut. Find here online price details of companies selling Friction Screw Press. A hydraulic energy piston could also be substituted for the screw and flywheel.
The invention pertains to a screw press having a flywheel rotationally related 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 equivalent to the utmost press stroke plus the width of the driving pinion, a plurality of pinions engaging 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. 3, strains 40 and 41 are representative of the screw stroke, and lines 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 3 is supported by the pistons 9 and 9′ towards 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 firm developed primarily based on SD20 Series Electrical Screw Press for the refractory industry. Shortly before the end of the downward stroke of the spindle 9 the rotational pace of the pump 27 and therefore the rotational pace 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 4-method valve forty one is displaced from the remainder position to the right and the line 42a is linked to a second strain-limiting valve forty three. The strain which might be regulated by the strain-limiting valve forty three limits, by way of the strain-limiting valve forty two, the stress present within the pipeline 31 to the braking pressure required for braking the flywheel 17. Relating to the current urgent machines, the number of strokes achieved between the washing phases of the moulds, is from 2 to three times as great. Since the electric motors are twice accelerated from relaxation to the required rotational speed and braked again throughout every operating cycle, correspondingly excessive current heat losses are unavoidable and in addition the idle power absorbed by the motor is disadvantageous. Experimentally, with a pressing machine in accordance with the present invention, it could be noticed that the mandatory energy for the first urgent operation, with predetermined masses of ceramic, may be quite low, approximately 10-12,000 kg., in opposition to the four hundred,000 Kg of the second pressing operations, which is quite different from the present pressing machines, which require about 50 to 150 tons for the primary urgent step.
Line 43 indicates the extraction of the pressed half by the mould because of the piston commanded by the respective valves 63 and 64 in synchronism with the beam and the screw in a new up motion achieved by known command circuits. SD10-315 was the primary set Refractory Electrical Program-controlled Screw Press for Refractory trade in China which was our company developped and produced, even the first set on this planet. Shortly before the affect of the upper half of the forging die, secured to the slide 7 upon the forging work-piece lying within the lower half of the forging die, the lines 31 to the axial piston motor 26 are brief-circuited, because the magnetically controlled 4-approach valve forty one is moved from its relaxation place (as proven in FIG. This Friction Screw Press Down Stroke has been developed from greatest grade steel. This machine can also be appropriate for producing naushadar bricks and head refractory. Change 23 energizes the valve 17 to disconnect the pilot of a test valve 22 and introduces oil at a stress of 100 atmospheres into the chambers 15 and 15′ of dynamic oil accumulators 14, 14′ which may be hydraulically linked to pistons 13, thirteen’ as shown in FIGS. The torlence of controlling power of Electrical Screw Press is zero.2%, and the torlence of affect power is only 1%. The small quantities of oil working off from the strain-limiting valves 42 and forty three and the 4-way valve forty one through the reversing and in addition as leaked oil are fed back once more into the closed circuit by a pump forty five driven by a motor 44. A spring-centered, pressure-managed three-approach valve forty six is provided with a view to ensure the feed strain required on the pump 27 and controlled by the pressure-limiting valve 47. The three-manner valve 46 is actuated in such a manner that the respective low-strain side of the closed circuit is connected to the strain-limiting valve 47, the feed pressure being maintained by the pump forty five. For cleansing and cooling the oil, the oil which has escaped from the circuit, is collected in part 32b of the tank 32, handed on after preliminary cleaning by sedimentation to part 32c of the tank 32, is fed through filters 50 and coolers 51 by a pump 49 pushed by an electric motor 48 and is saved in part 32a of the tank 32. Due to this fact, instead of ending the primary urgent with the value of the urgent, the amount of oil at high pressure could also be used. The electric screw press is driven by everlasting magnet synchronous servo motor,and encompass mechanical pats corresponding to framework, flywheel, screw nut, the slider, lubricating mechanism, braking mechanism and electrical parts similar to servo motor, electrical control cupboard, working button station.
Furthermore, the sum of the instances inherent to the first and second pressing step impeded discount of the period of a complete compacting cycle; and, the interval was at all times larger than three seconds. In response to the exemplary embodiment an axial piston motor 26 (fastened displacement motor) and an axial piston pump 27 (variable displacement pump), i.e. axial piston machines, are offered as these are probably the most appropriate. Throughout the fast up motion of beam three due to the pistons 9 and 9′, the oil retained within the pistons 2 and a couple of’ is pressured to exit by means of the valves sixty one and sixty one’ (FIGS. For the working stroke and the return stroke of the spindle 9 the extent of pivoting is restricted to a pivot angle which corresponds to the rotational pace of the spindle desired in each case and which determines the supply of the pump 27 at a continuing rotational speed of the electrical motor 28. A piston-cylinder association, which is acted upon, by way of the management 36, by a pump 39 driven by an electrical motor 38 in conjunction with a stress accumulator 40, acts because the actuating drive 37. Pistons 9, 9′ could also be mounted on base 72 for operative engagement of the plungers thereof with beam 3 for the return stroke of the beam 3 after the urgent cycle, and the ensuing emptying of the chambers related to the two pistons 2, 2′.
