Friction press, screw press with friction drive, is more extensively used in the equipment manufacturing industry. A compelled lubricating system will feed the lubricate oil into the closed screw-nut system by particular pipeline, and form an oil display screen between every touching parts to cut back the components friction when press works. A plurality of pinions engaging within the said toothed rim are every driven 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 higher cross member of the press frame. No. 3,359,608, issued to the present inventor, discloses a friction and screw press for the manufacture of ceramic articles. In response to the info present: data disparity, because the double-disc friction press operation will exist when stealing hammer, lacking hammer phenomenon, the output will be floater than the CNC electrical screw press, however in keeping with the provisions of the company to suppress the hammer products, Two kinds of pressure brick equipment manufacturing are comparable. Moreover, it’s possible to control the motion of the flywheel 7″ and screw 7′ by operating a hydraulic motor 7, having a comparatively diminished dimension, put in on the beam eight to move the screw 7 through a detachably coupled system which is hydraulically interconnected to pistons 9, 9′. Line forty one illustrates the return of the screw, which needs to be thrown in an up motion with a power of less worth than that provided for the elastic return of the structure of the urgent machine. The strain exerted by the screw 7′ on the material could also be predetermined in an exact method, with the potential of utilizing restricted torque mills for the stroke of the flywheel, such as hydraulic motors, electric motors or friction motors with restricted torque comparatively to the motor used up to this second. Through the acceleration phases for the downward movement and the upward movement of the spindle 9 the electric motor 28 operates with roughly constant power and constant rotational velocity which ensures a high diploma of electrical effectivity of the motor 28. The constant motor energy is transformed and absolutely utilized by the oil pump 27 operating as a torque converter. Mentioned circuit further comprising control means for controlling the strain of the hydraulic fluid fed to mentioned motor means and a plurality of pressure phases, one in every of stated phases being controllable as braking pressure for stated flywheel, and a refill pump means for returning leaked hydraulic fluid to said circuit.
The drive of the pistons thirteen, thirteen’ is predetermined by charging the dynamic oil accumulator 14 (with a kind of inert fuel cost) with the stress of the oil dynamic circuit derived from the pump 18 limiting it and discharging it with the utmost strain valve sixteen’. At present, the company’s products primarily embody: Friction Screw Press;J53, J54 series of double disc friction screw press; J67, J93 collection of refractory press; EP collection of electric screw press; MP sequence of hot forging press. The pressure utilized throughout this phase is, therefore, regulated by a pressostat which commands (at the same time with the timer and with the aim of disconnecting the intervening parts) the valves 56 and 57, respectively, shut the valves sixty one and 61′ of fast discharge of the pistons 2 and 2′. We are main industrial press machine supplier, specializing in production of top of the range press machines on the market, provide manufacturer worth press machine and refractory brick press for patrons, contact us for prompting your order. The time period of the prior phase 36 could also be changed, by altering the moment of stroke of the flywheel, for example, by a fixed signal hooked up to the ear plus a regulated timer, in such a method that the strain of the screw reaches the worth when the air is taken out from the mass to be pressed, with out unnecessary delays. On this condition, the screw spindle and the related flywheel function to execute solely the second comparting step and could also be thrown from their highest position with a coordinate anticipation and utilizing a decreased energy motor able to impart the due kinetic power in additional than a whole flip of the flywheel instead of in 1 / 4 flip. The lifting capability is 200tons, and we will assemble series press machine with nominal pressure from 160 tons to 8,000 tons Faithfulness, deploitation, innovation and good service is our basic managing principle. Enterprise Profile : Producers of Friction Screw Presses, Forging Press & Power Press. The control means for stated motor means embrace means capable of anticipate the starting of the lowering displacement of the flywheel and screw so that the second compacting step is carried out without delay instantly after the elastic return of the powder materials. Friction Screw Press Down Stroke is manufactured utilizing excessive grade stainless steel materials which supplies it a extremely sturdy service life. The pressure applied to the mass throughout this last part is given by the load of the beam three plus the strain of the pistons 5-5′, minus the power exerted by the pistons thirteen and thirteen’, which is opposite to the prior one, minus the eventual pistons 16″.
Business Profile : Jinan Linteng Forging Machinery Co., Ltd. Get info of suppliers, producers, exporters, traders of Friction Screw Press for purchasing in India. Certainly, in the first compacting step, the flywheel had to be thrown at excessive velocity to cut back the time of its vertical stroke and in addition, instantly braked before the affect to scale back its stress. The invention, nonetheless, just isn’t restricted to those axial piston machines, but appropriate oil pumps and oil motors of different design can also be used. Though the benefit, of lowered price and better reliability are achieved at the cost of a better electric motor drive capability, for the reason that substantial load compensation made possible by the hydraulic accumulator within the case of the previous type of drive with a central oil supply is absent, the electrical disadvantages (particularly excessive load peaks, further installations for limiting them, idle power of the motors) and the structural drawback of the spindle bearing within the case of a purely electrical drive are prevented, and with respect to the operational reliability within the case of the oil-hydraulic drive any drawback resulting from provision of further hydraulic elements (oil pumps and control means for each oil motor or pair of oil motors associated with a pinion) is more than compensated by the absence of the high-pressure oil ducts, particularly of the flexible parts compensating the movements of the press. Stated pressostat 19, when energized, determines the top of the HP (excessive stress) step, deenergizing the valves 20 and 17. Our extremely precision computerized press machine has the characteristics of easy structure, adjustable stress, high diploma of automation and productiveness. In summary the operation of the ingenious 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 transferring the beam downwardly towards the bottom into its working position, and third piston means 2, 2′ for exerting an extra downward force on the beam to move the beam toward the bottom and compress the ceramic powder to release air therefrom. Our press can save about 50% energy than friction press, so it may lower down large cost.
