EPC-D numerical control electrical screw press

EPC-D numerical control electrical screw press undertake switched reluctance motor which is essentially the most advanced and best suited for the die forging trade The motor with low speed and huge starting torque apply to the optimistic and unfavourable work.Subsequently, the lifetime of the motor is prolonged and saves energy.Digital management system use PLC control with man-machine interface integration while realizing the automation of forging manufacturing with robotic or different automation gear connectionThe pinion are made of particular steel, which solved the vulnerability downside of the bakelite gear without damaging gearwheel and prolonged the pinion life greater than 5 times than bakelite gear;The screw and the flywheel adopt the spline connection, which improves the workpiece interchangeability. Business Profile : Main manufacturer of Surface Grinder, Plano Miller, Planner Machine, Grinding and Milling Machinery, Machine Instruments & Equipment and Friction Screw Press used for Refractories. Depending upon the tooling employed on a press, it meets completely different needs of Non-Ferrous, Steel, Brass, Aluminium stamping’s, Hot Forgings and piercing operations. Friction screw press can be used in die forging, extruding, leading edge, bending and correcting for nonferrous and ferrous steel and pressing and forming work of refractory material as effectively. Furthermore, the regulation of the completely different phases amongst them, which is totally different from what would happen with the current machines, where the signalization of the primary and second pressing steps are related one to the opposite. The purpose 102″ is the arrival level after the first cycle, with the traditional urgent brick press machine. Thus, the total pressure time is 285 ms as in comparison with a minimum of 1,300 ms of the pressing machines. The third pair of hydraulic piston means are, in a most popular embodiment, single acting hydraulic jacks 5, 5′, every one having chamber full of oil at decreased stress through the reducing movement of the movable beam three and energized with an adequate excessive pressure, for performing the primary comparting step. Enterprise Profile : We are Producers and suppliers of; Forging Press Machine & Friction Screw Presses & Machine Tools, Down Stroke Machine and Up Stroke Machine.

The torque to be applied necessitates correspondingly giant and heavy motors which, apart from the truth that they’ve an unfavorable ratio of torque to moment of inertia, lead to the structural drawback that the spindle together with the flywheel and toothed rim have to be mounted axially non-displaceably within the upper cross member of the press frame and the spindle nut must be mounted within the slide of the press, and this leads to unfavorable publicity of the spindle to strain and torsion. The inclined portion 34 represents the second compression given by the action of the pistons 2 and a pair of’, or the effect of the oil stress of the oil coming into via the valve 55, commanded by the pilot 56 which is driven by a signal perform depending on the place of the beam 3 in the course of the down motion. The advantage of static strain kind press machine is its static pressure screw-nuts and the static stress bearing. All of the technical indicators and efficiency of the EPC-D electrical screw press produced by Qingdao Wantai Machine Device Technology Co. Ltd. No. three,359,608, a first and second compacting step had been carried out by a screw spindle, so that a lot of the pressing cycle time was consumed by the displacement of the screw spindle. 164 friction screw press machine products are provided on the market by suppliers on , of which punching machines accounts for 19%, hydraulic press accounts for 4%, and filter press equipment accounts for 1%. All kinds of friction screw press machine options can be found to you, There are 149 suppliers who sells friction screw press machine on , primarily situated in Asia. three. The pinions 23 are mounted in bearing blocks 24 which are supported by a platform 25 which surrounds the higher cross member 3 of the press body 1. Every pinion 23 is pushed by two axial piston motors, an axial piston motor 26o disposed above the pinion and an axial piston motor 26u disposed below the pinion 23. The width of the toothed rim 22 is such that during the full stroke of the spindle 9 executed by the toothed rim 22 the pinions 23 are at all times in complete engagement with the external toothing of the rim 22. Subsidy Mortgage Well as Screw Press forgingMachine Mortgage accessible on all sort of Industrial Initiatives. 2, line one hundred signifies the path of the beam 3 and the road one zero one the paths of the screw 7′ during the step of putting the press 70 into operation. 7 presses the overall discharge line 51 of the hydraulic circuit. Screw presses, which are ideally used as drop-forging machines on account of their design benefits, are restricted of their impact drive by friction wheel drive (friction screw presses), and due to this fact screw presses with an influence energy of from 40 MN (Meganewtons) are ceaselessly supplied, and screw presses with an impression of from eighty MN are basically offered, with a gearwheel drive, for which objective the flywheel has exterior toothing and has motor-pushed pinions engaging in its toothed rim.

The invention pertains 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 in the higher cross member of the press frame, wherein the flywheel has external toothing to a width equivalent to the utmost press stroke plus the width of the driving pinion, a plurality of pinions participating within 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 higher cross member of the press body. three, strains forty and forty one 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 excessive 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 ability of the pistons 9 and 9′ is such that it exceeds the load of the beam 3 and the pressure of the pistons 5 and 5′. This new construction is based on the refractory forming characters, which is our company developed based mostly on SD20 Collection Electric Screw Press for the refractory trade. Shortly before the tip of the downward stroke of the spindle 9 the rotational velocity 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 pace is diminished the four-means valve forty one is displaced from the rest place to the fitting and the line 42a is related to a second stress-limiting valve 43. The strain which might be regulated by the strain-limiting valve 43 limits, by way of the stress-limiting valve 42, the strain present in the pipeline 31 to the braking strain required for braking the flywheel 17. Concerning the present pressing machines, the variety of strokes achieved between the washing phases of the moulds, is from 2 to 3 times as great. For the reason that electric motors are twice accelerated from relaxation to the required rotational pace and braked once more throughout every operating cycle, correspondingly high present 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 present invention, it could be noticed that the necessary power for the primary urgent operation, with predetermined lots of ceramic, might be fairly low, approximately 10-12,000 kg., against the 400,000 Kg of the second pressing operations, which is sort of totally different from the present urgent machines, which require about 50 to 150 tons for the first urgent step.
