Description
Affiliated technical field the present invention relates to a kind of electric screw press, can be widely used in the excellent suitability for press forming industry.
The existing electric screw press of background technology, employed motor, switch on repeatedly when work, starting is frequent, and kurtosis often appears in electric load, dash current is big, power factor is lower, and electric motor overheating is more serious, and temperature rise is very high, 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, inrush current is little, electric motor overheating is light, starting torque is high, starting current is low, overload capacity is strong electric screw press.
In order to achieve the above object, electric screw press of the present invention, comprise fuselage, be installed in the cover of body upper, be fixed on the switched reluctance motor on the cover, flywheel by the switched reluctance motor driving, be fixed on the screw rod on the flywheel,, be fixed on the slide block on the nut by the nut of screw drive, 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 motor is stator, rotor biconvex utmost point VR motor, comprises stator and rotor.
Electric screw press of the present invention, its operation principle is: switched reluctance motor drives the flywheel rotation, and the flywheel rotation drives the screw rod rotation, screw rod moves downward by the screw pair drive nut, moves downward thereby drive slide block, 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, brake braking flywheel makes slide block be parked in initial position, finishes a working cycles.
Electric screw press of the present invention, said switched reluctance motor is the reversible motor, constantly does the commutation campaign of positive and negative direction, drives the rotation of flywheel and screw rod, by nut slide block is moved up and down.
Electric screw press of the present invention adopts switched reluctance motor 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.
Electric screw 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.
Electric screw 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.
Electric screw 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 motor in the power factor of unloaded and full load all greater than 0.98.Therefore, power factor height.
Electric screw press of the present invention, said switched reluctance motor, simpler than squirrel-cage AC asynchronous motor, the mechanical strength height, fault rate is low.
Electric screw press of the present invention, said switched reluctance motor, the soft start characteristic is arranged, no overshoot starting current, no common AC motor starting current is greater than the phenomenon of 5～7 times of rated current, but starting current smoothly increases to required electric current, and inrush current is little, and electric motor overheating is light.
Electric screw press of the present invention, said switched reluctance motor, 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.
Electric screw press of the present invention, said switched reluctance motor, overload capacity is strong, when load restoration just often, rotating speed returns to the setting rotating speed.
In sum, electric screw 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 electric motor overheating is light, the starting torque height, starting current is low, and overload capacity is strong.
Description of drawings is done further explanation below in conjunction with accompanying drawing and embodiment to the present invention.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the switched reluctance motor structural representation among Fig. 1.
The specific embodiment is in Fig. 1, electric screw press of the present invention, comprise fuselage 1, be installed in the cover 2 of fuselage 1 top, be fixed on the switched reluctance motor 3 on the cover 2, flywheel 4 by switched reluctance motor 3 drivings, be fixed on the screw rod 5 on the flywheel 4, the nut 6 by screw rod 5 drives is fixed on the slide block 7 on the nut 6, link to each other with slide block 7 and be fixed on slide block weight balance device 8 on the fuselage, be installed in the brake 9 that is used to brake flywheel on the fuselage; Said switched reluctance motor 3 is stator, rotor biconvex utmost point VR motor, comprises stator 10 and rotor 11.
In Fig. 1, electric screw press of the present invention can be provided with ejector 12 according to arts demand, and switched reluctance motor can drive flywheel by belt drive, also can drive flywheel by other modes.
In Fig. 2, electric screw press of the present invention, said switched reluctance motor, stator, rotor form by silicon steel plate stacking, have not both had winding on the rotor and have not also had permanent magnet, are wound with concentrated winding on the stator poles, two radially relative windings in series constitute the two poles of the earth magnetic pole, are called a phase.Switched reluctance motor can be designed to the multiple different number of phases and number of poles structure, and the number of poles of stator, rotor is always inequality, and multiple different collocation is arranged, and this special combining form can be used on fly press fully.
In Fig. 2, electric screw press of the present invention, said switched reluctance motor, its operation principle is: the switched reluctance motor among the figure is 8/6 utmost point, four phases.As original position, give D → a → b → c phase winding energising with the relative position of stator, rotor successively, rotor promptly can be against the excitation order with rotation continuously counterclockwise; Otherwise, switch on for successively B → A → d → c mutually, then motor can the clockwise direction rotation.As seen, turning to the sense of current of phase winding of switched reluctance motor is irrelevant, and depends on the order of phase winding energising.Organize S by what control and the every phase winding of motor were connected in series mutually
