For the effect of the kinetic vitality collected on the flywheel 2″ through the stroke and which is discharged at the moment of contact with the prepressed and already without air mass, the extent 39 develops a robust instantaneous stress, with a period of, roughly, thirty-5 thousandths of a second. 3. A flywheel and screw press based on claim 1, whereby stated flywheel and screw are movable from an upper position and a lower position, the latter being the place wherein the second compacting step is performed, the area from the upper and the lower position being such that the flywheel and the screw must rotate at about a turn for moving from one to the other position. Since our inception, we’re engaged in manufacturing a classy array of Friction Screw Press, that are designed to be dependable, environment friendly and exact for Scorching Forging of Steel, Brass, Aluminium to our esteemed shoppers.
Thus, in accordance with the invention, there may be offered a flywheel and screw press for producing ceramic articles comprising, in combination, a base seventy two having an upper surface; a hard and fast head 71; help means seventy three, 73 supporting stated fastened head 71 in mounted position upwardly spaced from said higher floor of mentioned base 72; a movable beam 3 located within the house between stated upper surface and said fastened head seventy one and being guided on mentioned assist means 73, seventy four for motion towards and away from stated higher floor; mould means carried by mentioned base 71 and supplied with cavities open upwardly for receiving a charge of ceramic powder materials, punch means carried by mentioned movable beam three and designed to cooperate with mentioned cavities for forming ceramic articles, a first pair of hydraulic piston means 9, 9′ carried by said base 72 and supplied for imparting an upwardly directed thrust to mentioned movable beam three; a second pair of hydraulic piston means carried by mentioned fastened head and offered for imparting a downwardly directed thrust to said movable beam three, mentioned first 9, 9′ and second 6, 6′ pair of hydraulic piston means cooperating for controlling the downward stroke of said movable beam 3 for imparting to the powder within the cavities a comfortable pre-compression inflicting a primary thickness discount of the powder mass and an appreciable expulsion of the air enclosed; a 3rd pair of hydraulic piston means 5, 5′ carried by said fixed head 7 and managed for acting on the movable beam three and performing the primary compacting step after the gentle pre-compression; a fourth pair of elastically compressible hydraulic piston means thirteen, thirteen’ carried by stated base 72 and supplied with adjustable rod ends and able to intervene with said movable beam 3 when the latter is additional lowered throughout mentioned first compacting step for impressing to stated movable beam three an upwardly directed thrust serving to the elastic return of the compacted powder mass to boost stated movable beam 3 instantly after said first compacting step, permitting the expulsion of the remaining air; a flywheel 7″ disposed above said mounted heat 71, a screw 7′ threadedly engaged to stated flywheel 7″ and carried by said fastened head seventy one; motor means 7 provided for alternatively imparting to said flywheel 7″ and screw 7′ rotation in a single and in the other course for decreasing and raising flywheel and screw, and management means for controlling stated motor means 7 to function mentioned flywheel and screw within the decreasing direction in due time for impacting said movable beam three and performing a powerful second and ultimate compacting step of the powder material instantly after the elastical return of the powder materials; and hydraulic circuit means for well timed controlling and energizing all of the pairs of mentioned hydraulic piston means, said hydraulic circuit interconnecting all of the pairs of mentioned hydraulic piston means.
A compelled lubricating system will feed the lubricate oil into the closed screw-nut system by means of special pipeline, and type an oil screen between each touching parts to scale back the parts friction when press works. A plurality of pinions engaging in the mentioned 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 together 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. Based on the data show: data disparity, as a result of the double-disc friction press operation will exist when stealing hammer, lacking hammer phenomenon, the output will probably be floater than the CNC electric screw press, but in response to the provisions of the corporate to suppress the hammer merchandise, Two kinds of strain brick gear manufacturing are comparable. Furthermore, it’s potential to control the movement of the flywheel 7″ and screw 7′ by operating a hydraulic motor 7, having a comparatively reduced dimension, installed on the beam 8 to maneuver 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 must be thrown in an up motion with an influence of much less worth than that equipped for the elastic return of the structure of the pressing machine. The stress exerted by the screw 7′ on the material may be predetermined in a precise manner, with the potential for utilizing restricted torque turbines for the stroke of the flywheel, similar to hydraulic motors, electric motors or friction motors with restricted torque comparatively to the motor used up to this moment. During the acceleration phases for the downward movement and the upward movement of the spindle 9 the electrical motor 28 operates with roughly constant power and fixed rotational speed which ensures a excessive diploma of electrical effectivity of the motor 28. The fixed motor energy is converted and totally utilized by the oil pump 27 working as a torque converter. Said circuit further comprising control means for controlling the strain of the hydraulic fluid fed to stated motor means and a plurality of pressure stages, one of stated stages being controllable as braking pressure for said flywheel, and a refill pump means for returning leaked hydraulic fluid to stated circuit.
As a way to supply the oil-hydraulic motors, an oil station is required which includes an electrical motor, oil pump, high-pressure accumulator and control devices as well as gadgets for filtering and cooling the oil, and which in addition to the press is disposed on the office ground, in a basement or on a scaffold and is linked to the oil-hydraulic motors by means of flexible excessive-stress ducts which compensate for the movements of the press. All pistons operate at one hundred atm, roughly, as working pressure. 9, the step represented by line 30 represents the quick lowering down stroke path of the beam 3 resulting from its own 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 line portion 31 is the braked down motion to satisfy the mass to be pressed at filling (level 32) with low pace, with a purpose to avoid the expulsion of the ceramic powder from the casting mould and a violent contact between the punches and the moulds, in the case of mirror moulds (nonpentrating). Is a brand new product which built-in screw press advangtage of south china and north construction adopts the break up physique and solves the problem of the rack fracture ,which has the characteristics of simple and cheap gear construction, lovely look, simple operation, maintenance and technique 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 equipment is principally used within the precision forging of ferrous metals, nonferrous metals, refractory materials and different industries. Based on the invention every axial piston motor or each pair of axial piston motors respectively associated with a pinion has related to it on the platform a controllable pump which is driven by a respective electrical motor and is reversible with respect to the fluid provide direction.
