We’re a leading producer, provider & exporter of Press Machine that’s specifically designed by our experienced professionals at our technically advanced infrastructure. The invention relates 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 in the upper cross member of the press frame, wherein the flywheel has external toothing to a width similar to the utmost press stroke plus the width of the driving pinion, a plurality of pinions participating within the said 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 together with the pinions are disposed on a platform surrounding the higher cross member of the press frame. 3, traces 40 and 41 are consultant of the screw stroke, and lines 30, 31, 31′, 33, 34, 35, 36 and forty three are representative of the stroke of beam 3. 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 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 company developed primarily based on SD20 Series Electric Screw Press for the refractory business. Shortly earlier than the end of the downward stroke of the spindle 9 the rotational speed of the pump 27 and therefore the rotational velocity 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 four-way valve 41 is displaced from the remainder place to the proper and the road 42a is connected to a second stress-limiting valve forty three. The pressure which may be regulated by the pressure-limiting valve 43 limits, by way of the pressure-limiting valve 42, the pressure current within the pipeline 31 to the braking pressure 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 three times as nice. Because the electrical motors are twice accelerated from rest to the required rotational speed and braked again throughout each working cycle, correspondingly excessive present heat 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 would be observed that the required power for the primary pressing operation, with predetermined masses of ceramic, could be quite low, approximately 10-12,000 kg., towards the 400,000 Kg of the second urgent operations, which is quite different from the current urgent machines, which require about 50 to 150 tons for the primary urgent step.
Jinan Linteng Forging Machinery Co., Ltd. Degree forty two is the one reached after the material has suffered the stress of the screw and represents the ultimate disposition of the pressed mass. EPC-D numerical management electric screw press undertake switched reluctance motor which is essentially the most advanced and most suitable for the die forging business The motor with low pace and enormous beginning torque apply to the constructive and destructive work.Subsequently, the life of the motor is prolonged and saves power.Electronic management system use PLC management with man-machine interface integration while realizing the automation of forging manufacturing with robot or different automation gear connectionThe pinion are fabricated from particular metal, which solved the vulnerability downside of the bakelite gear without damaging gearwheel and prolonged the pinion life greater than 5 occasions than bakelite gear;The screw and the flywheel undertake the spline connection, which improves the workpiece interchangeability.

Furthermore, the regulation of the different phases amongst them, which is completely different from what would happen with the current machines, the place the signalization of the first and second pressing steps are related one to the other. The purpose 102″ is the arrival point after the primary cycle, with the traditional urgent machine. Thus, the whole stress time is 285 ms as in comparison with a minimal of 1,300 ms of the pressing machines. The third pair of hydraulic piston means are, in a most popular embodiment, single performing hydraulic jacks 5, 5′, each having chamber crammed with oil at reduced pressure throughout the lowering motion of the movable beam three and energized with an sufficient high strain, for performing the primary comparting step.

Furthermore, the sum of the times inherent to the first and second pressing step impeded reduction of the interval of a whole compacting cycle; and, the period was all the time better than three seconds. In accordance with the exemplary embodiment an axial piston motor 26 (fixed displacement motor) and an axial piston pump 27 (variable displacement pump), i.e. axial piston machines, are offered as these are essentially the most appropriate. During the fast up movement of beam 3 because of the pistons 9 and 9′, the oil retained within the pistons 2 and a couple of’ is pressured to exit via the valves 61 and 61′ (FIGS. For the working stroke and the return stroke of the spindle 9 the extent of pivoting is proscribed to a pivot angle which corresponds to the rotational speed of the spindle desired in each case and which determines the delivery of the pump 27 at a relentless rotational pace of the electrical motor 28. A piston-cylinder arrangement, which is acted upon, by means of the control 36, by a pump 39 driven by an electrical motor 38 at the side of a strain accumulator forty, acts as 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 associated with the two pistons 2, 2′. Disadvantages of Friction Disk Screw Press: long transmission chain and excessive energy consumption, extra fast-wear parts,not accurate controlling and labor-intensive, noisy, unsafe, etc. The press, with easy in construction, giant energy, low noise, lengthy life, protected and dependable in operation, handy service etc, may be extensively used in aviation, auto, tractor, tool manufacturing, textiles machinery industries and many others.

Double-disk Friction Screw Press In Uganda. In accordance with the current invention, if there is no such thing as a inversion of the flywheel between the primary and second urgent operation, there’s much less put on and a minor use of energy to operate the press. This computerized electrical screw press is a multiple practical fire bricks molding machine. This advantageously means that the torque utilized to the flywheel could also be thrown by a motor immediately and coaxially mounted on the flywheel, and not by a disc friction system.
