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 upper cross member of the press body, whereby the flywheel has external toothing to a width corresponding to the utmost press stroke plus the width of the driving pinion, a plurality of pinions partaking in the stated 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 together with the pinions are disposed on a platform surrounding the upper cross member of the press body. 3, traces forty and forty one 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 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 power of the pistons 9 and 9′ is such that it exceeds the load 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 Collection Electric Screw Press for the refractory industry. Shortly earlier than the end of the downward stroke of the spindle 9 the rotational velocity of the pump 27 and hence the rotational speed of the flywheel 17 and the spindle 9 are reduced to zero during the rest of the stroke of the spindle 9. When the rotational speed is decreased the 4-method valve forty one is displaced from the rest position to the correct and the road 42a is linked to a second strain-limiting valve forty three. The pressure which might be regulated by the stress-limiting valve forty three limits, by the use of the strain-limiting valve 42, the stress present in the pipeline 31 to the braking strain required for braking the flywheel 17. Relating to the present urgent machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to three times as nice. Because the electrical motors are twice accelerated from rest to the required rotational pace and braked again during every working cycle, correspondingly excessive current warmth losses are unavoidable and in addition the idle energy absorbed by the motor is disadvantageous. Experimentally, with a pressing machine in accordance with the current invention, it could be observed that the necessary energy for the primary pressing operation, with predetermined masses of ceramic, may be quite low, approximately 10-12,000 kg., in opposition to the 400,000 Kg of the second urgent operations, which is sort of completely different from the current pressing machines, which require about 50 to 150 tons for the primary pressing step.

The 2 axial piston motors 26o and 26u related to a respective one of many pinions 23 are each 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 each pinion 23 concurrently supporting the axial piston motors 26o and 26u, the oil pump 27 and the electrical motor 28, which are associated with this pinion 23. Each oil pump 27 could be regulated by way of its feed pressure and its feed quantity and is reversible with respect to its feed course. Electrical motors or oil-hyraulic motors are used for driving the pinions.
4, by one axial piston motor 26. The axial piston motor 26 is fed by the oil pump 27 which is driven by the electrical motor 28. When the feed route of the pump 27 is reversed there may be also a change within the course of rotation of the axial piston motor 26 which in a single path of rotation effects the downward movement of the spindle 9 for the working stroke and in the other course of rotation effects the upward movement of the spindle 9 in order to return to the starting position. Business Profile : GRD Mechanical Works is among the leading Producer & Supplier of All Sorts of Power Press, Friction Screw Press, Forging Press & Machinery Parts and lots of more. The time for such programs is determinable, by delaying the strain part of the pistons 2 and 2′ via the valves 55 and 56. The flywheel and screw are movable from an higher position and a decrease position, the latter being the position wherein the second compacting step is performed, the house from the higher and the decrease position being such that the flywheel and the screw must rotate at a few turn for shifting from one to the opposite place. It’s part of the enterprise transformation of the scene graph, Disadvantage of Friction Disk Screw Press: Long transmission chain and high energy loss. To be able to cut back the structural expenditure and to increase the operational reliability, every axial piston motor or pair of axial piston motors associated with a pinion has related to it on the platform a controllable pump which is driven by a respective electric motor and is reversible with respect to the circulation route. button operation to complete the hearth bricks producing;no radial force.

The step represented by line 31′ is the continuation of the down motion of the beam 3 after the conclusion of the section 31 of the braking, is the urgent till meeting the equilibrium point between the pressure utilized and the reaction pressure of the mass then pressed (at degree 37). The forging forces don’t act on the machine body but are sustained by the Ram. A pressostat 18 calibrated at 90 environment, energizes a valve 20 which feeds a multiplier 21 taking the mandatory stress to the oil, with this pressure being predetermined through a pressostat 19.
Business Profile : Jinan Linteng Forging Machinery Co., Ltd. Get information of suppliers, manufacturers, exporters, merchants of Friction Screw Press for getting in India. Indeed, within the first compacting step, the flywheel needed to be thrown at excessive velocity to cut back the time of its vertical stroke and in addition, instantly braked earlier than the impact to reduce its stress. The invention, nonetheless, just isn’t restricted to those axial piston machines, but suitable oil pumps and oil motors of other design can be used. Though the benefit, of decreased value and larger reliability are achieved at the price of a higher electric motor drive capacity, since the substantial load compensation made possible by the hydraulic accumulator in the case of the previous sort of drive with a central oil provide is absent, the electrical disadvantages (particularly excessive load peaks, additional installations for limiting them, idle power of the motors) and the structural disadvantage of the spindle bearing in the case of a purely electrical drive are averted, and with respect to the operational reliability in the case of the oil-hydraulic drive any disadvantage as a consequence of provision of further hydraulic parts (oil pumps and management means for every oil motor or pair of oil motors related to a pinion) is greater than compensated by the absence of the high-pressure oil ducts, particularly of the versatile portions compensating the movements of the press. Said pressostat 19, when energized, determines the top of the HP (high pressure) step, deenergizing the valves 20 and 17. Our ultra precision automatic press machine has the characteristics of easy structure, adjustable strain, high degree of automation and productivity. In abstract the operation of the inventive press makes use of first piston means 9, 9′ to move the beam upwardly or retract the beam from the base, second piston means 5, 5′ for shifting the beam downwardly towards the base into its operating place, and third piston means 2, 2′ for exerting a further downward force on the beam to maneuver the beam towards the base and compress the ceramic powder to launch air therefrom. Our press can save about 50% energy than friction press, so it could actually minimize down large cost.
