Description
Affiliated technical field the present invention relates to a kind of stepper motor direct drive electric fly press, can be widely used in the excellent suitability for press forming industry.
The existing electric screw press of background technology, 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 speed governing, operate steadily, respond fast, good internally-damped characteristic, electric efficiency height are arranged, electric current is little, heating is low, noise is low, vibration is little, mechanical strength is high, fault rate is low, simple in structure, driving-chain is lacked, the parts loss is little, cost is low, the stepper motor direct drive electric fly press of easy to maintenance, long service life.
In order to achieve the above object, stepper motor direct drive electric fly press of the present invention, comprise fuselage, be installed in the stepper motor of body upper, flywheel driven by stepper motors 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 stepper motor comprises stator that is installed on the fuselage and the rotor that is installed on the flywheel.
Stepper motor direct drive electric fly press of the present invention, its operation principle is: stepper motor 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.
Stepper motor direct drive electric fly press of the present invention, said stepper motor 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.Stepper motor is a kind of electric pulse to be converted into the executing agency of angular displacement, and it can change digital pulse signal into mechanical angle displacement or displacement of the lines.Its displacement (angle or length) has strict corresponding relationship with the input pulse signal, and it is synchronous that motor speed and input pulse frequency can keep.When step actuator receives a pulse signal, it just drives stepper motor and rotates a fixing angle by the direction of setting, and can come the pilot angle displacement by the control impuls number, thereby reach the purpose of accurate location; Simultaneously, can control speed and the acceleration that motor rotates, thereby reach the purpose of speed governing by the control impuls frequency.In speed and position control system, that the stepping motor drive system has is reliable, simple in structure, cost is low, advantage such as easy to maintenance.Its step angle value and rotary speed can not accomplished quick startup, counter-rotating and braking because of factors such as voltage, electric current, temperature fluctuate.
Stepper motor direct drive electric fly press of the present invention, said stepper motor operates steadily, and response has good internally-damped characteristic fast, the electric efficiency height, electric current is little, and it is low to generate heat, and reduces temperature rise greatly and improves reliability, there is not obviously vibration district, sound construction, noise is low, vibrates little.
Stepper motor direct drive electric fly press of the present invention, said stepper motor, simpler than squirrel-cage AC induction motor, the mechanical strength height, fault rate is low.
Stepper motor direct drive electric fly press of the present invention adopts the direct transmission of motor, does not need intermediate drive, designs simplification, and parts are few, and are simple in structure, and 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, the parts loss is little.
Stepper motor direct drive electric fly press of the present invention adopts stepper 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.
Stepper motor 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, long service life.
Stepper motor direct drive electric fly press of the present invention, said stepper motor generally adopts open loop control, in case of necessity, also can realize closed-loop control.
In sum, stepper motor direct drive electric fly press of the present invention, speed governing operates steadily, response has good internally-damped characteristic, the electric efficiency height fast, electric current is little, and it is low to generate heat, and noise is low, vibrate little, the mechanical strength height, fault rate is low, simple in structure, driving-chain is short, and the parts loss is little, cost is low, and is easy to maintenance, long service life.
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.
The specific embodiment is in Fig. 1, stepper motor direct drive electric fly press of the present invention, comprise fuselage 1, be installed in the stepper motor 2 of body upper, flywheel 3 driven by stepper motors is fixed on the screw rod 4 on the flywheel, by the slide block 5 of screw rod by the screw pair driving, link to each other with slide block and be fixed on slide block weight balance device 6 on the fuselage, be installed in the brake 7 that is used to brake flywheel on the fuselage; Said stepper motor 2 comprises stator 2-1 that is installed on the fuselage and the rotor 2-2 that is installed on the flywheel.
