A compact design and a rise in operational reliability are achieved if, every axial piston motor or every pair of axial piston motors which is associated with a pinion and the associated reversible pump are disposed in a closed circuit which also contains the control means for feed pressure and a number of-stage stress controllable in a single stage as braking strain and which is linked to a refill pump. So as to cut back the investment for production gear, we will also make the modification from outdated type friction screw press to new electric screw press. Capability of forging hydraulic press we’ve made is as much as 50000 tons and as much as a hundred and twenty tons for manipulator and up to 8 meters in diameter for ring rolling mill. The ingredient of the primary urgent operation is disposed coaxially reverse to the compacting piston or beam 3 on base seventy two, if the principle pressing aspect is a hydraulic piston. The thing of the invention is to cut back the structural value of these screw presses at the same time as rising operational reliability. A screw press has a flywheel rotationally related to the press spindle by means of a friction coupling. Each circuit can have associated with it its own 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 interior facet walls 33i, outer aspect walls 33a and the bottom 33b, the trough 33 supporting your complete oil hydraulic system and being adequately dimensioned to receive all of the oil present within the oil circuit. The highest nations of suppliers are India, China, from which the percentage of friction screw press machine supply is 3%, 96% respectively. Double-disk friction screw press is a commonly used friction screw press which is widely used for compression moulding of die forging, extrusion, scrap reduce, bending, revision and refractory of ferrous and non-ferrous metal.
The invention relates to a screw press having a flywheel rotationally linked to the spindle by way of a friction coupling and a spindle displaceable axially in a nut mounted in the upper cross member of the press body, whereby the flywheel has exterior toothing to a width similar to the utmost press stroke plus the width of the driving pinion, a plurality of pinions engaging within the stated 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 higher cross member of the press body. three, lines 40 and 41 are consultant 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 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 weight of the beam three 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 mostly on SD20 Sequence Electrical Screw Press for the refractory industry. Shortly earlier than the top of the downward stroke of the spindle 9 the rotational velocity of the pump 27 and therefore the rotational speed of the flywheel 17 and the spindle 9 are diminished to zero during the remainder of the stroke of the spindle 9. When the rotational pace is decreased the 4-means valve forty one is displaced from the remainder place to the right and the road 42a is linked to a second stress-limiting valve 43. The stress which could be regulated by the stress-limiting valve 43 limits, by the use of the stress-limiting valve 42, the pressure current in the pipeline 31 to the braking strain required for braking the flywheel 17. Concerning the current pressing machines, the number of strokes achieved between the washing phases of the moulds, is from 2 to three instances as great. Since the electric motors are twice accelerated from rest to the required rotational speed and braked again throughout each working cycle, correspondingly excessive current 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 would be observed that the mandatory energy for the first urgent operation, with predetermined lots of ceramic, may be quite low, roughly 10-12,000 kg., towards the four hundred,000 Kg of the second urgent operations, which is quite different from the current urgent machines, which require about 50 to a hundred and fifty tons for the first pressing step.
