Description
Technical field the present invention relates to a kind of twin-screw electric screw press, can be widely used in the excellent suitability for press forming industry.
The existing electric screw press of background technology, are all single screw-rod structures, and slide block bears eccentrically loaded ability, are unwell to the die forging of multimode thorax.For large pressing machine, screw diameter is large, and lifting, transportation and manufacture difficulty, restricted the development of Large Electric fly press.
Summary of the invention the object of the present invention is to provide that a kind of screw diameter is little, easy to manufacture, equipment enlarging, offset load resistance is strong, work top is large, the die forging of multimode thorax, transmission efficiency are high, good energy-conserving effect, the twin-screw electric screw press that simple in structure, parts are few, driving-chain is short, the parts loss is little, cost is low, simple to operate, easy to maintenance.
In order to achieve the above object, twin-screw electric screw press of the present invention, comprise frame, be arranged on the slide block on rack rail, embed the left copper nut of installing in slide block, right copper nut, be arranged on frame and be arranged on respectively left copper nut, left screw rod on right copper nut, right screw rod, be arranged on respectively left screw rod, the left gear formula flywheel of right screw rod upper end, right gear formula flywheel, vertical rack-mounted four motors, be arranged on each motor output shaft and respectively with left gear formula flywheel, two left driving gears of right gear formula flywheel engaged transmission, two right driving gears, lay respectively at left gear formula flywheel, right gear formula flywheel top rack-mounted left fly wheel brake, right fly wheel brake, be arranged in frame and be arranged on the kicker cylinder on slide block, said left screw rod and right screw rod, its thread rotary orientation is contrary, said left gear formula flywheel, right gear formula flywheel, the two intermeshing transmission.
Twin-screw electric screw press of the present invention, said frame, comprise sill, is arranged on the column on sill, is arranged on the entablature on column, the turnbuckle that sill, column, entablature are tightened together.
Twin-screw electric screw press of the present invention, said motor, be buncher.
Twin-screw electric screw press of the present invention, its operation principle is: motor drives driving gear, and driving gear is the wheeled flywheel of driving gear again, the rotation of gear type flywheel drive screw, drive slide block down by screw rod and the copper nut screw pair be fixed in slide block, realize the workpiece excellent suitability for press forming.Then, motor reversal also drives by kicker cylinder, and slide block turns back to upper limit position.Two wheeled flywheels of intermeshing canine tooth, stored energy on the one hand, guarantee the synchronism of slide block movement on the other hand.
Twin-screw electric screw press of the present invention, the effect of inertia of two flywheels is cancelled each other when hitting, and has avoided the torsional pulse of single screw spiral forcing press, has reduced the requirement to ground.With same specification list screw spiral forcing press, compare, each screw diameter is less, and lifting, transportation and handling ease can be manufactured the electric screw press of large specification, easy to manufacture, are convenient to realize equipment enlarging.
Twin-screw electric screw press of the present invention, said two left driving gears, two right driving gears, each driving gear is all driven by a motor separately, and is directly installed on motor output shaft.
Twin-screw electric screw press of the present invention, owing to adopting many to press the motor-driven that the gear wheel periphery of flywheel is evenly installed, eliminated the lateral pressure to screw rod and bearing thereof, can bear larger eccentric load, offset load resistance is strong, and work top is large, is easy to carry out the die forging of multimode thorax.
Twin-screw electric screw press of the present invention, compare with single screw rod electric screw press, and power of motor is little, and little to the electrical network impact, the electric motor starting electric current is little, and transmission efficiency is more than 58%, and transmission efficiency is high, and energy-saving effect is remarkable.Two gear type flywheel energy storages, can realize flywheel energy adjustment and programme-control.
Twin-screw electric screw press of the present invention, compare with friction screw press, without intermediate gearings such as frictional disk, transverse axis, do not need intermediate drive, driving-chain is short, also without the friction belt consumable accessory on friction screw press, does not have frictional dissipation and wear problem in frictional drive.Compare with hydraulic screw press, do not need Hydraulically Operated Equipment complicated, that have relatively high expectations, do not have the hydraulic fluid leak contaminated environment and the hydraulic fault problem occurs.Therefore, the present invention is simple in structure, and parts are few, and driving-chain is short, and the parts loss is little, easy to manufacture, and cost is low, simple to operate.
Twin-screw electric screw press of the present invention, the kind of drive is simple, and maintenance workload is very little, saves labour and maintenance cost, is convenient to maintenance and repair.Therefore, easy to maintenance.
Twin-screw electric screw press of the present invention, during forcing press work, can not produce the normal operation of impacting and affecting miscellaneous equipment to electrical network, during feeding, discharge, motor is not worked, energy-saving and cost-reducing, there is no traditional friction screw press frictional disk idle running power consumption, more energy-conservation more than 50% than friction screw press.
Twin-screw electric screw press of the present invention, without bottom dead centre, needn't adjust mold height, and the forging precision is high, can vexed car under load, can realize closed die forging, can realize the repeatedly strike under different-energy to same forging, the contact mould time is short, and die life is long, and hitting power is stable.
In sum, twin-screw electric screw press of the present invention, screw diameter is little, easy to manufacture, equipment enlarging, offset load resistance is strong, work top is large, the die forging of multimode thorax, and transmission efficiency is high, good energy-conserving effect, simple in structure, parts are few, driving-chain is short, and the parts loss is little, and cost is low, simple to operate, easy to maintenance.
