The direct driving type electric spiral press machine has simple structure, short transmission chain, easy production, low cost, convenient maintenance, small loss of mechanical partial elements, high power factor, high mechanical intensity, low failure rate, soft start property, small starting impact current, light heating of the motor, high starting torque, low starting current and strong overloading ability and does not have an overshoot starting current, therefore, the direct driving type electric spiral press machine can be widely applied to the forging and pressing forming industry.
Description
Affiliated technical field the present invention relates to a kind of direct drive electric fly press, can be widely used in the excellent suitability for press forming industry.
Background technology
Existing electric screw press, employed motor is switched on when work repeatedly, and starting is frequent, kurtosis often appears in electric load, and dash current is big, and power factor is lower, and it is relatively more serious that the motor feels hot, temperature rise is very high, and power loss is big, thereby the motor of selecting for use is also very big; In order to prevent that motor from burning out, also will be with air blast in the cooling of ceaselessly ventilating of whole working time, total power of motor of installation is big; Because the required whole energy of each run are all obtained by electrical network in moment, therefore, very big to the electrical network impact, specification is big more, and is also just big more to the influence of electrical network.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, driving-chain short, easy to manufacture, cost is low, easy to maintenance, accessory loss is little, power factor is high, mechanical strength is high, fault rate is low, the soft start characteristic is arranged, no overshoot starting current, that inrush current is little, the motor feels hot is light, starting torque is high, starting current is low, overload capacity is strong direct drive electric fly press.
In order to achieve the above object, direct drive electric fly press of the present invention, comprise fuselage, be installed in the switched reluctance machines of body upper, flywheel by switched reluctance machines drives is fixed on the screw rod on the flywheel, by the slide block of screw rod by the screw pair driving, link to each other with slide block and be fixed on slide block weight balance device on the fuselage, be installed in the brake that is used to brake flywheel on the fuselage; Said switched reluctance machines comprises stator that is installed on the fuselage and the rotor that is installed on the flywheel.
Direct drive electric fly press of the present invention, its operation principle is: switched reluctance machines directly drives the flywheel rotation, and the flywheel rotation drives the screw rod rotation, and screw rod drives slide block by screw pair and moves downward, and realizes excellent suitability for press forming; After the strike, the energy of fly wheel system all discharges and finishes, and motor counter-rotating then rises to predetermined altitude with slide block, the motor outage, and brake braking flywheel makes slide block be parked in initial position, finishes a working cycles.
Direct drive electric fly press of the present invention, said switched reluctance machines is the reversible motor, constantly does the commutation campaign of positive and negative direction, drives the rotation of flywheel and screw rod, by screw pair slide block is moved up and down.
Direct drive electric fly press of the present invention adopts switched reluctance machines directly to drive, and compares with friction screw press, does not need transverse axis, frictional disk, two support arms of rotating; Compare with hydraulic screw press, do not need hydraulic system complicated, that have relatively high expectations.Therefore, parts are few, and are simple in structure, and equipment volume is little, stable action, and rotational noise is very little, and driving-chain is short, and is easy to manufacture, in light weight, is convenient to install, and cost is low.
Direct drive electric fly press of the present invention, the kind of drive is simple, and maintenance workload is very little, and labor savings and maintenance cost are convenient to maintenance and repair.Therefore, easy to maintenance.
Direct drive electric fly press of the present invention, adopt the direct transmission of motor, do not need intermediate drive, designs simplification, parts are few, and are simple in structure, driving-chain is short, do not have complicated hydraulic system and electrical control equipment, do not have the friction material consumable accessory on the friction screw press yet, do not have frictional dissipation and wear problem in the frictional drive.Therefore, accessory loss is little.
Direct drive electric fly press of the present invention, the power factor when common alternating current generator is unloaded is 0.2～0.4, full load is 0.8～0.9; And the power factor of switched reluctance machines in the power factor of unloaded and full load all greater than 0.98.Therefore, power factor height.
Direct drive electric fly press of the present invention, said switched reluctance machines, simpler than squirrel-cage AC induction motor, the mechanical strength height, fault rate is low.
Direct drive electric fly press of the present invention, said switched reluctance machines, the soft start characteristic is arranged, no overshoot starting current, there be not the phenomenon of common alternating current generator starting current greater than 5～7 times of rated current, but starting current smoothly increases to required electric current, and inrush current is little, and it is light that the motor feels hot.
Direct drive electric fly press of the present invention, said switched reluctance machines, frequent forward and backward, stops Fraquent start, and starting torque reaches 150% o'clock of nominal torque, and starting current only is 30% of a rated current.Therefore, the starting torque height, starting current is low.
Direct drive electric fly press of the present invention, said switched reluctance machines, overload capacity is strong, when load restoration just often, rotating speed returns to the setting rotating speed.
In sum, direct drive electric fly press of the present invention, simple in structure, driving-chain is short, and easy to manufacture, cost is low, easy to maintenance, the mechanical part accessory loss is little, the power factor height, the mechanical strength height, fault rate is low, and the soft start characteristic is arranged, no overshoot starting current, inrush current is little, and it is light that the motor feels hot, the starting torque height, starting current is low, and overload capacity is strong.
