To be able to reduce the investment for production equipment, we can additionally modify the old kind friction screw press into new electrical screw press.Disadvantages of Friction Disk Screw Press: long transmission chain and excessive power consumption, more fast-put on elements,not correct controlling and labor-intensive, noisy, unsafe, and so forth. 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 higher cross member of the press body, whereby the flywheel has external toothing to a width comparable to the utmost press stroke plus the width of the driving pinion, a plurality of pinions partaking within the mentioned toothed rim are each driven 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, strains 40 and 41 are consultant of the screw stroke, and features 30, 31, 31′, 33, 34, 35, 36 and forty three are representative of the stroke of beam three. In a high place 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 ability of the pistons 9 and 9′ is such that it exceeds the load of the beam 3 and the force of the pistons 5 and 5′. This new construction is based on the refractory forming characters, which is our firm developed based on SD20 Series Electric Screw Press for the refractory business. Shortly earlier than the top of the downward stroke of the spindle 9 the rotational speed of the pump 27 and hence the rotational velocity 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 velocity is reduced the four-manner valve 41 is displaced from the remaining place to the fitting and the line 42a is linked to a second stress-limiting valve 43. The pressure which will be regulated by the stress-limiting valve 43 limits, by the use of the pressure-limiting valve 42, the pressure current in the pipeline 31 to the braking stress required for braking the flywheel 17. Regarding the current urgent machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to three times as great. For the reason that electrical motors are twice accelerated from relaxation to the required rotational speed and braked once more during every operating cycle, correspondingly excessive present heat losses are unavoidable and also the idle energy absorbed by the motor is disadvantageous. Experimentally, with a urgent machine in accordance with the current invention, it might be observed that the necessary energy for the primary pressing operation, with predetermined lots of ceramic, may be quite low, approximately 10-12,000 kg., towards the 400,000 Kg of the second pressing operations, which is quite completely different from the present pressing machines, which require about 50 to 150 tons for the first pressing step.
