The invention pertains to a screw press having a flywheel rotationally connected to the spindle by way of a friction coupling and a spindle displaceable axially in a nut mounted within the upper cross member of the press frame, whereby the flywheel has external toothing to a width corresponding to the utmost refractory press stroke plus the width of the driving pinion, a plurality of pinions engaging in the said 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 along with the pinions are disposed on a platform surrounding the higher cross member of the press frame. 3, traces forty and 41 are representative of the screw stroke, and contours 30, 31, 31′, 33, 34, 35, 36 and forty three are consultant of the stroke of beam 3. In a excessive position 30 the beam three is supported by the pistons 9 and 9′ against 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 3 and the pressure of the pistons 5 and 5′. This new construction relies on the refractory forming characters, which is our company developed primarily based on SD20 Collection Electric Screw Press for the refractory business. Shortly before the tip of the downward stroke of the spindle 9 the rotational pace of the pump 27 and hence the rotational pace of the flywheel 17 and the spindle 9 are diminished to zero throughout the rest of the stroke of the spindle 9. When the rotational speed is diminished the 4-method valve 41 is displaced from the remaining place to the proper and the line 42a is connected to a second pressure-limiting valve forty three. The strain which may be regulated by the strain-limiting valve 43 limits, by way of the pressure-limiting valve 42, the stress present within the pipeline 31 to the braking strain required for braking the flywheel 17. Regarding the present urgent machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to 3 occasions as nice. Since the electric motors are twice accelerated from relaxation to the required rotational pace and braked again throughout each working cycle, correspondingly high present heat losses are unavoidable and also the idle energy absorbed by the motor is disadvantageous. Experimentally, with a pressing machine in accordance with the current invention, it could be noticed that the required power for the first pressing operation, with predetermined plenty of ceramic, will be fairly low, approximately 10-12,000 kg., towards the 400,000 Kg of the second urgent operations, which is kind of different from the current pressing machines, which require about 50 to a hundred and fifty tons for the primary urgent step.
A flywheel and screw press for compacting a ceramic powder includes a base, a fixed press member disposed at a spaced location above the bottom, a beam movably positioned in the area between the bottom and the fixed press member, and a plurality of hydraulic piston members mounted to the base and the mounted press member for variably controlling the compaction of the ceramic powder. The invention relates, typically, to ceramic body presses and, extra particularly, to an improved flywheel and screw press for producing ceramic or refractory articles.

With a view to provide the oil-hydraulic motors, an oil station is required which contains an electric motor, oil pump, high-strain accumulator and management units as well as units for filtering and cooling the oil, and which along with the press is disposed on the workplace flooring, in a basement or on a scaffold and is related to the oil-hydraulic motors by the use of versatile high-strain ducts which compensate for the movements of the press. All pistons operate at a hundred atm, approximately, as working stress. 9, the step represented by line 30 represents the quick lowering down stroke path of the beam 3 as a result of its personal weight and the action of the pistons 5 and 5′ when the discharge of the pistons 9 and 9′ is commanded by the valves eight-12 and 10. The line portion 31 is the braked down movement to fulfill the mass to be pressed at filling (level 32) with low velocity, as a way to avoid the expulsion of the ceramic powder from the casting mould and a violent contact between the punches and the moulds, within the case of mirror moulds (nonpentrating). Is a new product which built-in screw press advangtage of south china and north construction adopts the break up physique and solves the problem of the rack fracture ,which has the traits of straightforward and affordable gear structure, stunning appearance, straightforward operation, maintenance and technique to finish the work of workstation is that the motor drives pinion and then pinion drives flywheel rotating with energy releasing for the necessities of the equipment is principally used within the precision forging of ferrous metals, nonferrous metals, refractory materials and different industries.

four, by one axial piston motor 26. The axial piston motor 26 is fed by the oil pump 27 which is driven by the electric motor 28. When the feed direction of the pump 27 is reversed there’s also a change within the path of rotation of the axial piston motor 26 which in one route of rotation effects the downward motion of the spindle 9 for the working stroke and within the different direction of rotation effects the upward motion of the spindle 9 so as to return to the starting place. Enterprise Profile : GRD Mechanical Works is one of the main Producer & Supplier of All Kinds of Power Press, Friction Screw Press, Forging Press & Equipment Parts and plenty of more. The time for such courses is determinable, by delaying the stress phase of the pistons 2 and a pair of’ via the valves fifty five and 56. The flywheel and screw are movable from an upper place and a lower position, the latter being the position whereby the second compacting step is carried out, the area from the higher and the decrease place being such that the flywheel and the screw should rotate at about a turn for shifting from one to the opposite position. It is a part of the enterprise transformation of the scene graph, Disadvantage of Friction Disk Screw Press: Long transmission chain and excessive power loss.
