We are a number one manufacturer, provider & exporter of Press Machine that is specially designed by our experienced professionals at our technically superior infrastructure. The invention relates to a screw press having a flywheel rotationally related to the spindle by the use of a friction coupling and a spindle displaceable axially in a nut mounted within the higher cross member of the press body, 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 engaging within the mentioned 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 along with the pinions are disposed on a platform surrounding the upper cross member of the press frame. three, traces 40 and 41 are representative of the screw stroke, and lines 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 three 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 drive of the pistons 5 and 5′. This new structure is predicated on the refractory forming characters, which is our company developed based on SD20 Collection Electric Screw Press for the refractory trade. 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 lowered to zero during the rest of the stroke of the spindle 9. When the rotational speed is diminished the four-method valve 41 is displaced from the rest place to the appropriate and the road 42a is linked to a second strain-limiting valve 43. The strain which will be regulated by the pressure-limiting valve 43 limits, by means of the stress-limiting valve 42, the pressure current within the pipeline 31 to the braking strain required for braking the flywheel 17. Regarding the current urgent machines, the number of strokes achieved between the washing phases of the moulds, is from 2 to 3 instances as great. Because the electric motors are twice accelerated from rest to the required rotational velocity and braked again during each working cycle, correspondingly excessive 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 would be observed that the required power for the first pressing operation, with predetermined lots of ceramic, will be quite low, approximately 10-12,000 kg., against the four hundred,000 Kg of the second urgent operations, which is quite different from the present urgent machines, which require about 50 to one hundred fifty tons for the first pressing step.
Moreover, the sum of the times inherent to the first and second pressing step impeded reduction of the period of a whole compacting cycle; and, the period was at all times greater than three seconds. Based on 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 three due to the pistons 9 and 9′, the oil retained in the pistons 2 and a pair of’ is forced to exit via the valves 61 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 speed of the spindle desired in every case and which determines the delivery of the pump 27 at a relentless rotational velocity of the electric motor 28. A piston-cylinder arrangement, which is acted upon, by way of the control 36, by a pump 39 driven by an electrical motor 38 in conjunction with a pressure accumulator 40, acts because the actuating drive 37. Pistons 9, 9′ may be mounted on base 72 for operative engagement of the plungers thereof with beam 3 for the return stroke of the beam three after the pressing cycle, and the consequent emptying of the chambers related to the 2 pistons 2, 2′. Disadvantages of Friction Disk Screw Press: lengthy transmission chain and excessive energy consumption, more quick-wear elements,not accurate controlling and labor-intensive, noisy, unsafe, and so forth.

Refractory Recycling Crusher refractory cost of installation in uaecement Basalt Crusher CELLULAR CRUSHER Mobile Crusher concrete recycling; crushing equipment; coal mining gear; sand making machine; about refractory value of set up in uaecement. Double-disk Friction Screw Press In Uganda. In accordance with the present invention, if there is no inversion of the flywheel between the first and second pressing operation, there may be less wear and a minor use of vitality to operate the press. This computerized electrical screw press is a multiple functional fireplace bricks molding machine. This advantageously implies 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.

A compact design and an increase in operational reliability are achieved if, every axial piston motor or each pair of axial piston motors which is associated with a pinion and the related reversible pump are disposed in a closed circuit which additionally contains the control means for feed stress and multiple-stage strain controllable in one stage as braking pressure and which is related to a refill pump. With the intention to scale back the funding for manufacturing tools, we are able to additionally make the modification from previous type friction screw press to new electric screw press. Capability of forging hydraulic press we’ve made is up to 50000 tons and up to one hundred twenty tons for manipulator and up to eight meters in diameter for ring rolling mill. No. three,359,608 chambers of the pistons 2, 2′ are fed by an illustrative circuit, which provides a controlled oil quantity at high stress, or stress regulation by way of a “pressostat” 18 or 19, proven in FIG. Double disk friction screw press中文雙盤摩擦壓力機，點擊查查權威綫上辭典詳細解釋double disk friction screw press的中文翻譯，double disk friction screw press的發音，音標，用法和例句等。 The element of the primary urgent operation is disposed coaxially reverse to the compacting piston or beam three on base 72, if the primary urgent component is a hydraulic piston. The object of the invention is to reduce the structural price of these screw presses at the same time as increasing operational reliability. A screw press has a flywheel rotationally connected to the press spindle by way of a friction coupling. Every circuit can have related to it its personal oil tank 32, or the circuits of one half of the press or all the circuits can have a typical oil tank 32. The platform 25 is shaped as a trough 33 with inside facet partitions 33i, outer facet walls 33a and the base 33b, the trough 33 supporting all the oil hydraulic system and being adequately dimensioned to receive all of the oil current in the oil circuit.

The torque to be applied necessitates correspondingly massive and heavy motors which, aside from the truth that they’ve an unfavorable ratio of torque to second of inertia, result in the structural disadvantage that the spindle together with the flywheel and toothed rim have to be mounted axially non-displaceably within the upper cross member of the press frame and the spindle nut must be mounted within the slide of the press, and this results in unfavorable exposure of the spindle to stress and torsion. The inclined portion 34 represents the second compression given by the motion of the pistons 2 and 2′, or the impact of the oil strain of the oil entering by way of the valve 55, commanded by the pilot 56 which is driven by a sign perform depending on the position of the beam 3 throughout the down movement. The benefit of static pressure type press machine is its static strain screw-nuts and the static pressure bearing. All the technical indicators and efficiency of the EPC-D electrical screw press produced by Qingdao Wantai Machine Device Expertise Co. Ltd. No. 3,359,608, a first and second compacting step had been performed by a screw spindle, in order that a lot of the pressing cycle time was consumed by the displacement of the screw spindle. 164 friction screw press machine merchandise are offered on the market by suppliers on , of which punching machines accounts for 19%, hydraulic press accounts for four%, and filter press tools accounts for 1%.
