The use of the friction screw presses


31 May

Appropriate for the new forging of each type of material, the friction screw presses are used for the production of full elements brick press machine. The motor has been equipped with encoder, appropriate for accurate control. The advantage of static pressure kind press is its static strain screw-nuts and the static pressure all these parts are designed to be in a closed screw rotates, the nut will drive the slide block to move up and down.


Screw is CrMoV high alloy forging, thread kind has good fatigue resistance, no self-lock, steady set up, brief screw, elevated press rigidity. The screw rotor propels the oil supplies inward and squeeze them. Patented in the 12 months 1900 by Valerius Anderson, the flights on the screws of those presses have interruptions which reduce co-rotation.


In operation, the worm shaft conveys, presses and squeezes the fabric (digested palm fruit) for oil extraction. AC servo numerical control electrical fly press of the present invention, AC servo numerical control electric machine undertake strengthens output shaft, so the anti-bias load capability is robust, and is safe and reliable.


After enter start sign, motor from stationary state drives slide speed up downwards through pinion and gearwheel, motor stop accelerating after reaching required pace by pre-set blow energy, Kinetic vitality stored by gearwheel works, e.g. forming work.


2. Idiot-type operation, no want of skilled press machine operator. Twin screw presses characteristic two overlapping compression screws. The picture shows excellent feature application of the screw press on hot pressing of Magnesium thin sheet to carry out backward extrusion and boss forming.


The torque to be applied necessitates correspondingly large and heavy motors which, other than the truth that they've an unfavorable ratio of torque to second of inertia, lead to the structural disadvantage that the spindle along with the flywheel and toothed rim must be mounted axially non-displaceably within the higher cross member of the press frame and the spindle nut must be mounted within the slide of the press, and this leads to unfavorable exposure of the spindle to stress and torsion.


J58K-EP sequence NC electric screw press is a home advanced numerical management electrical screw press developed by the domestic scientific analysis institute and soak up advanced electrical screw press know-how in world. The oil supplies in the squeezing chamber is motorial.


Strong structure of motor rotor, which may stand up to impacting load, locked rotor and phase cannot burn the controller and motor. Forging machines are basically double-appearing mechanical presses working in a horizontal plane. This press consists of body, drive, flywheel, slide, operation, brake, lubrication, electric, foundation ,and so forth.


The heat generated by friction can improve the yield of the oil press, and let the oil flows from the gaps. Last press cake moisture is managed by a discharge cone (or door), which is actuated by an air cylinder. Is one of the most effective cold oil press machine developed newly.


As we speak almost all presses are driven by electric motors. Remarks: In case of the servo pushed machine, measured rum pace previous to the forging is nearly even. The friction screw presses incorporate all some great benefits of the drop hammers and of the eccentric presses but they don't have their deficiencies and limitations.
