We’re engaged in manufacturing a spread of Screw Presses, which are used to dewater and wash secondary as well as virgin fiber. These presses require a smaller funding than the one of many screw presses with electrical servomotor, but they need the leather belt replacement, essential for the slide motion when it wears. Technical field the utility mannequin relates to a kind of electric screw press that is match to processing refractory brick or makes use of for forging, punching press.
The spindle is displaced axially in a nut mounted in the upper cross member of the press body, and the flywheel has exterior toothing with a width similar to the utmost pressing stroke plus the width of the driving pinions. A uniform strain is exerted on the pulp sheets, positioned between the platens with the help of wheel mounted on the lead screw.
AC servo numerical management electrical fly press of the current invention, AC servo numerical control electrical machine need steady operations as conventional friction press.As a result of motor can generate electricity in the course of the flywheel braking, regain regenerated vitality, thereby reduced the wastage in bulk or weight of the the various work below rated situation point of forcing press, many AC servos numerical control electrical machine is lower than other motor power consumption, and is when low cruise, vitality-conservation extra forcing press when work, can not produce the normal operation of impacting and influence miscellaneous gear to electrical network, and motor shouldn’t be worked throughout upper and decrease material, and is power-saving and cost-reducing, don’t had conventional friction screw press frictional disk idle working to consume energy, extra vitality-conservation more than 50% than friction screw press.
AC servo numerical management electric fly press of the current invention, the each strike in the circulation need not brake operating.Behind the ability connection, mechanical braking can unclamp instantly.After forging completion, AC servo numerical control electric machine drives slide block and rises, and slows down at certain position, stops at prime dead-centre ultimately.Due to this fact, mechanical braking has solely in case of emergency simply and uses, and has extended brake service life, tremendously reduces maintenance price.
A dewatering screw press is a screw press that separates liquids from solids A screw press can be used instead of a belt press, centrifuge , or filter paper It is a simple, sluggish moving device that accomplishes dewatering by continuous gravitational drainage.
1, be the structural illustration of the utility model electric screw 2, be the electrical principle schematic of electrical screw press. Forging machines are rated for size according to the utmost bar dimension for which they will provide an upset head. It’s tough to fabricate massive tonnage of pressure machine and precision elements because of its precept and construction constraints.
The screw press is highly effective as a result of it makes use of all flywheel power throughout forming. Discover the differences between these kinds of screw press by studying this text. Where,Pm is the power of the electric motor and η is the drive efficiency.
AC servo numerical control electric fly press of the present invention, no backside dead centre needn’t be adjusted mould peak; Forge that precision is high, vitality is large, can vexed car beneath the load, can notice closed die forging; Can realize the repeatedly strike below the completely different-power to similar forging; The contact mould time is brief, and die life is long, and hitting power is secure.
