To be able to provide the oil-hydraulic motors, an oil station is required which includes an electrical motor, oil pump, excessive-stress accumulator and management gadgets as well as devices for filtering and cooling the oil, and which along with the press is disposed on the office ground, in a basement or on a scaffold and is connected to the oil-hydraulic motors by means of flexible high-strain ducts which compensate for the movements of the press. All pistons operate at one hundred atm, roughly, as working strain. 9, the step represented by line 30 represents the quick reducing down stroke path of the beam three because of its personal weight and the motion of the pistons 5 and 5′ when the discharge of the pistons 9 and 9′ is commanded by the valves 8-12 and 10. The road portion 31 is the braked down motion to satisfy the mass to be pressed at filling (degree 32) with low speed, so as to keep away from 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 structure adopts the break up physique and solves the problem of the rack fracture ,which has the traits of simple and reasonable equipment structure, stunning look, straightforward operation, maintenance and methodology to complete the work of workstation is that the motor drives pinion and then pinion drives flywheel rotating with energy releasing for the necessities of the gear is mainly used within the precision forging of ferrous metals, nonferrous metals, refractory supplies and different industries.

The 2 axial piston motors 26o and 26u associated with a respective one of the pinions 23 are every fed by an oil pump 27 which in flip is driven by a respective electric motor 28 in every case, the bearing block 24 of every pinion 23 concurrently supporting the axial piston motors 26o and 26u, the oil pump 27 and the electric motor 28, which are related to this pinion 23. Every oil pump 27 might be regulated when it comes to its feed strain and its feed amount and is reversible with respect to its feed course. Electrical motors or oil-hyraulic motors are used for driving the pinions.
The invention relates to a screw press having a flywheel rotationally related 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 body, wherein the flywheel has exterior toothing to a width comparable to the utmost press stroke plus the width of the driving pinion, a plurality of pinions engaging in the said 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 together with the pinions are disposed on a platform surrounding the upper cross member of the press frame. three, traces forty and 41 are representative of the screw stroke, and features 30, 31, 31′, 33, 34, 35, 36 and 43 are representative of the stroke of beam 3. In a high position 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 facility of the pistons 9 and 9′ is such that it exceeds the load of the beam three and the pressure of the pistons 5 and 5′. This new construction is based on the refractory forming characters, which is our firm developed primarily based on SD20 Collection Electrical Screw Press for the refractory industry. 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 reduced to zero during the remainder of the stroke of the spindle 9. When the rotational speed is lowered the 4-approach valve 41 is displaced from the rest position to the precise and the line 42a is linked to a second stress-limiting valve forty three. The pressure which will be regulated by the pressure-limiting valve forty three limits, by way of the pressure-limiting valve forty two, the pressure current in the pipeline 31 to the braking stress required for braking the flywheel 17. Relating to the present pressing machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to 3 occasions as great. Since the electrical motors are twice accelerated from rest to the required rotational speed and braked again throughout every operating cycle, correspondingly excessive present heat losses are unavoidable and in addition the idle power absorbed by the motor is disadvantageous. Experimentally, with a pressing machine in accordance with the current invention, it might be noticed that the required energy for the first pressing operation, with predetermined masses of ceramic, might be fairly low, approximately 10-12,000 kg., towards the 400,000 Kg of the second pressing operations, which is quite totally different from the present pressing machines, which require about 50 to a hundred and fifty tons for the primary urgent step.
