So as to scale back the investment for production gear, we are able to also modify the previous kind friction screw press into new electrical screw press.Disadvantages of Friction Disk Screw Press: long transmission chain and high power consumption, more quick-put on elements,not accurate controlling and labor-intensive, noisy, unsafe, and so on. The invention pertains to a screw press having a flywheel rotationally connected to the spindle by the use 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 external toothing to a width comparable to the maximum press stroke plus the width of the driving pinion, a plurality of pinions participating within the stated toothed rim are every 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 higher cross member of the press body. three, lines 40 and 41 are consultant of the screw stroke, and lines 30, 31, 31′, 33, 34, 35, 36 and forty three are consultant of the stroke of beam three. In a high place 30 the beam three is supported by the pistons 9 and 9′ towards 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 drive of the pistons 5 and 5′. This new structure is based on the refractory forming characters, which is our firm developed primarily based on SD20 Series Electric Screw Press for the refractory industry. Shortly earlier than the tip of the downward stroke of the spindle 9 the rotational pace of the pump 27 and therefore the rotational velocity of the flywheel 17 and the spindle 9 are diminished to zero throughout the remainder of the stroke of the spindle 9. When the rotational pace is lowered the four-way valve 41 is displaced from the rest place to the proper and the line 42a is linked to a second pressure-limiting valve forty three. The stress which will be regulated by the stress-limiting valve forty three limits, by way of the pressure-limiting valve 42, the stress current 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 instances as great. For the reason that electrical motors are twice accelerated from rest to the required rotational speed and braked once more during every operating cycle, correspondingly excessive present heat losses are unavoidable and likewise the idle power absorbed by the motor is disadvantageous. Experimentally, with a urgent machine in accordance with the present invention, it would be observed that the necessary energy for the primary urgent operation, with predetermined plenty of ceramic, can be quite low, roughly 10-12,000 kg., against the four hundred,000 Kg of the second pressing operations, which is sort of totally different from the present urgent machines, which require about 50 to one hundred fifty tons for the primary urgent step.

A pressured lubricating system will feed the lubricate oil into the closed screw-nut system through particular pipeline, and type an oil screen between each touching parts to reduce the parts friction when press works. A plurality of pinions participating in the said toothed rim are each pushed by an oil-hydraulic axial piston motor 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 upper cross member of the press frame. No. three,359,608, issued to the current inventor, discloses a friction and screw press for the manufacture of ceramic articles. According to the data show: knowledge disparity, as a result of the double-disc friction press operation will exist when stealing hammer, missing hammer phenomenon, the output might be floater than the CNC electric screw press, however in line with the provisions of the company to suppress the hammer products, Two kinds of pressure brick gear production are comparable. Furthermore, it’s possible to manage the movement of the flywheel 7″ and screw 7′ by operating a hydraulic motor 7, having a relatively reduced dimension, installed on the beam eight to move the screw 7 via a detachably coupled system which is hydraulically interconnected to pistons 9, 9′. Line 41 illustrates the return of the screw, which needs to be thrown in an up motion with an influence of less value than that equipped for the elastic return of the structure of the pressing machine. The strain exerted by the screw 7′ on the material may be predetermined in an exact manner, with the potential of utilizing limited torque mills for the stroke of the flywheel, equivalent to hydraulic motors, electric motors or friction motors with limited torque relatively to the motor used up to this moment. Through the acceleration phases for the downward movement and the upward movement of the spindle 9 the electrical motor 28 operates with roughly constant energy and constant rotational speed which ensures a excessive degree of electrical efficiency of the motor 28. The constant motor power is converted and absolutely utilized by the oil pump 27 working as a torque converter. Mentioned circuit additional comprising control means for controlling the pressure of the hydraulic fluid fed to stated motor means and a plurality of strain phases, one in every of said phases being controllable as braking strain for said flywheel, and a refill pump means for returning leaked hydraulic fluid to said circuit.

Oil-hydraulic motors, specifically axial piston motors, have a subtantially decrease particular weight with small dimensions than electric motors, so that they are often arranged, individually or in pairs, on diametrically opposite a driving pinion, with the further structural benefit that the spindle along with the flywheel and the toothed rim might be mounted axially displaceably in a nut mounted within the upper cross member of the press body and are thus exposed only to torsion above the nut and only to thrust below the nut. Discover here online price particulars of corporations selling Friction Screw Press. A hydraulic energy piston may be substituted for the screw and flywheel.

The torque to be utilized necessitates correspondingly large and heavy motors which, aside from the fact that they’ve an unfavorable ratio of torque to second of inertia, result in the structural disadvantage that the spindle along with the flywheel and toothed rim should be mounted axially non-displaceably in the upper cross member of the press body and the spindle nut should be mounted in the slide of the press, and this ends in unfavorable exposure of the spindle to pressure and torsion. The inclined portion 34 represents the second compression given by the action of the pistons 2 and a pair of’, or the impact of the oil stress of the oil coming into via the valve fifty five, commanded by the pilot 56 which is driven by a signal function dependent on the position of the beam three during the down movement. The advantage of static stress sort press machine is its static strain screw-nuts and the static strain bearing. All of the technical indicators and performance of the EPC-D electrical screw press produced by Qingdao Wantai Machine Instrument Know-how Co. Ltd. No. three,359,608, a first and second compacting step were performed by a screw spindle, in order that a lot of the urgent cycle time was consumed by the displacement of the screw spindle. 164 friction screw press machine products are supplied for sale by suppliers on , of which punching machines accounts for 19%, hydraulic press accounts for four%, and filter press tools accounts for 1%.
