Description
Affiliated technical field
The present invention relates to a kind of many motor switch reluctance 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.In addition, general drive motors has only one, the driving requirement of incompatibility large-scale spiral forcing press low-speed big.
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, have wide range of applications, low-speed big, to the shock-free many motor switch reluctance electric of electrical network fly press.
In order to achieve the above object, many motor switch of the present invention reluctance electric fly press, comprise frame, the vertical a plurality of switched reluctance machines that are installed on the housiung separator, be installed in the small active gear on the switched reluctance machines output shaft, by the big flywheel of small active gear by the meshed transmission gear driving, be installed in the screw rod on the big flywheel, 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 housiung separator top is used to brake flywheel, be installed in the ejector of frame bottom.
Many motor switch of the present invention reluctance electric fly press, its operation principle is: switched reluctance machines directly drives small active gear, and small active gear drives big flywheel rotation then, thereby drives the screw rod rotation, last screw rod drives slide block by screw pair and moves downward, realize the excellent suitability for press forming process, 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.
Many motor switch of the present invention reluctance electric fly press adopts switched reluctance machines, realizes the frequent rotating operation of high low speed.Compare with other motors, 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.
Many motor switch of the present invention reluctance electric fly press, 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.
Many motor switch of the present invention reluctance electric fly press, 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.
Many motor switch of the present invention reluctance electric fly press, small active gear is directly installed on the electric machine main shaft of structure reinforcement, and the mechanical strength height has been eliminated the harmful effect of hitting vibration, guaranteed the coaxial of motor shaft and pinion, thereby axiality is good, the forming accuracy height, drive motors main shaft phenomenon of rupture can not appear, overload capacity is strong, operates steadily, and rotational noise is very little.
Many motor switch of the present invention reluctance electric fly press also has energy-saving advantages, the many work below rated condition point of forcing press, and switched reluctance machines 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.
Many motor switch of the present invention reluctance electric fly press, 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.
Many motor switch of the present invention reluctance electric fly press 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.
Many motor switch of the present invention reluctance electric fly press because of at the big a plurality of drive motors of flywheel arranged around, and adopts and strengthens output shaft, so the anti-bias load ability is strong, and is safe and reliable.
Many motor switch of the present invention reluctance electric fly press adopts the transmission of multi-gear one-level, has solved the low-speed big problem, and adapts to the driving requirement of large-scale spiral forcing press low-speed big.
In sum, many motor switch of the present invention reluctance electric fly press, simple in structure, parts are few, driving-chain is short, and the mechanical strength height is easy to manufacture, easy to maintenance, cost is low, and is simple to operate, and the parts loss is little, and axiality is good, overload capacity is strong, operates steadily, and the forming accuracy height, the anti-bias load ability is strong, safe and reliable, long service life, energy-conservation, have wide range of applications, low-speed big does not have impact to electrical network.
