Description
Affiliated technical field the present invention relates to a kind of frequency conversion numerical control electric fly press, can be widely used in the excellent suitability for press forming industry.
The existing electric screw press of background technology is switched on when work repeatedly, and starting is frequent, and kurtosis often appears in electric load, dash current is big, and power factor is lower, and electric motor overheating is more serious, 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 motor power (output) 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, parts are few, driving-chain is short, mechanical strength is high, easy to manufacture, easy to maintenance, cost is low, simple to operate, the parts loss is little, axiality good, overload capacity is strong, operate steadily, forming accuracy height, anti-bias load ability are strong, safe and reliable, long service life, energy-conservation, Technological adaptability strong, low-speed big, to the shock-free frequency conversion numerical control electric of electrical network fly press.
In order to achieve the above object, frequency conversion numerical control electric fly press of the present invention, comprise frame, vertical rack-mounted a plurality of frequency conversion numerical control electric machines, be installed in the pinion on the frequency conversion numerical control electric machine main shaft, by the gear wheel of pinion by the meshed transmission gear driving, be installed in the screw rod on the gear wheel, by the slide block of screw rod by the screw pair driving, be installed in the balance bar that is used to promote the slide block backhaul on the frame, be installed in the brake that the frame top is used to brake flywheel, be installed in the ejector of frame bottom.
Frequency conversion numerical control electric fly press of the present invention, its operation principle is: motor drives slide block movement through pinion, gear wheel, screw rod, gear wheel has enough inertia, play a part flywheel energy storage, after the input enabling signal, motor drives slide block by inactive state through pinion, gear wheel and quickens descendingly, and electrical motors is during to the desired rotating speed of blow energy that sets in advance, the kinetic energy work done that utilizes gear wheel to store is shaped product.After gear wheel released energy, motor drove gear wheel counter-rotating immediately, return certain corner after, motor enters on-position, makes gear wheel drive slide block and gets back to the position that sets in advance, the one action circulation is promptly finished.
Frequency conversion numerical control electric fly press of the present invention adopts the power source of the threephase asynchronous of frequency converter driving as forcing press, and the electric current during motor starting is little, and starting torque is big, and electrical network is not had impact; Because frequency converter is a kind of intelligence controlling device of motor, can change the operation characteristic of motor according to the technological requirement of made workpiece, thereby change the kinetic characteristic of forcing press, satisfy the manufacturability requirement of various different workpieces, expanded the scope of application of forcing press.Because forcing press motor during upper and lower material etc. is auxiliary is not worked, and compares with traditional friction press, widely saves energy.
Frequency conversion numerical control electric fly press of the present invention, the threephase asynchronous that adopts frequency converter to drive is realized the frequent rotating operation of high low speed.Compare with other motor, have the following advantages:
(1) can conveniently adjust blow speed, to adapt to the requirement of different process deformation velocity;
(2) response speed is fast, the efficient height;
(3) starting torque is big, and starting current is little, and electrical network is not had impact, is fit to the requirement of the frequent rotating starting of heavy fly press;
(4) adopted the line efficiency optimization of going forward side by side of advanced control mode, no-load current is little, and energy-saving effect is remarkable;
(5) element integrated level height, antijamming capability is strong, good reliability.
Frequency conversion numerical control electric fly press of the present invention, compare with friction screw press, intermediate gearings such as no frictional disk, transverse axis, promptly do not need intermediate drive, driving-chain is short, do not have the friction band consumable accessory on the friction screw press yet, do not have frictional dissipation and wear problem in the 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, and is easy to manufacture, and cost is low, and is simple to operate.
Frequency conversion numerical control 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.
Frequency conversion numerical control electric fly press of the present invention, pinion is directly installed on the motor main shaft of structure reinforcement, and the mechanical strength height has been eliminated the harmful effect of hitting vibration, guaranteed the coaxial of motor reel and pinion, thereby axiality is good, the forming accuracy height, drive motor main shaft phenomenon of rupture can not appear, overload capacity is strong, operates steadily, and rotational noise is very little.
Frequency conversion numerical control electric fly press of the present invention also has energy-saving advantages, the many work below rated condition point of forcing press, and frequency conversion numerical control electric machine is lower than other motor power consumption, and is when low cruise, energy-conservation more obvious.In forcing press when work, can not produce the normal operation of impacting and influence miscellaneous equipment to electrical network, and motor is not worked during upper and lower material, and is energy-saving and cost-reducing, do not had traditional friction screw press frictional disk idle running to consume energy, more energy-conservation more than 50% than friction screw press.
Frequency conversion numerical control electric fly press of the present invention, no bottom dead centre, needn't adjust mold height, forge the precision height, energy is big, can vexed car under the load, can realize closed die forging, can realize repeatedly strike under the different-energy to same forging, the contact mould time is short, and die life is long, and hitting power is stable.
Frequency conversion numerical control electric fly press of the present invention is to utilize impulsive force to make the equipment of workpiece deformation, and the technology applicability is strong, can be used for cold conditions punching press, impression, smoothing, bending of forge hot and plate etc., can be used for finish forge, finishing again; Stainless steel composite bottom boiler pressure welding technique can be applicable to, the precision forging of bent axle, titanium alloy blade and other blades can be applicable to again.Therefore, have wide range of applications.
Frequency conversion numerical control electric fly press of the present invention because of at a plurality of drive motors of gear wheel arranged around, and adopts and strengthens output shaft, so the anti-bias load ability is strong, and is safe and reliable.
