Description
Affiliated technical field the present invention relates to a kind of pair and drives electric screw press, can be widely used in the excellent suitability for press forming industry.
The existing electric screw press of background technology, general drive motors has only one, and force-bearing situation is bad.Switch on repeatedly when work, starting is frequent, and 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, and 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, 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 and compact, parts are few, driving-chain is short, mechanical strength is high, force-bearing situation is good, 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, shock-free pair of electrical network driven electric screw press.
In order to achieve the above object, the two electric screw press that drive of the present invention, comprise frame, the vertical two drive motors that are installed on the housiung separator of symmetry, be installed in the small active gear on two drive motors output shafts, by the gear wheel of small active gear 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 compensating cylinder 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.
The two electric screw press that drive of the present invention, its operation principle is: two drive motors directly drive small active gear, and small active gear drives the gear wheel rotation then, thereby drive 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.
The present invention is two to drive electric screw press, and said gear wheel plays a part flywheel.
The two electric screw press that drive of the present invention because of the two drive motors that adopt symmetry to install, can be cancelled out each other to the impulsive force of gear wheel, and force-bearing situation is good, operates steadily, and has reduced the volume of single motor simultaneously, compact conformation.
The two electric screw press that drive of the present invention adopt two drive motors, realize the frequent rotating operation of high low speed, 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.
The present invention is two to drive electric screw press, compares intermediate gearings such as no frictional disk, transverse axis with friction screw press, promptly do not need intermediate drive, driving-chain is short, does not also have the friction band consumable accessory on the friction screw press, does 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.
The present invention is two to drive electric screw press, and 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.
The two electric screw press that drive of the present invention, small active gear is directly installed on the motor output 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.
The present invention is two to drive electric screw press and also has energy-saving advantages, and forcing press is many works rated condition point below, and two drive motors consume energy low than other motor, 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.
The present invention is two to drive electric screw press, and no bottom dead centre needn't be adjusted mold height, and forging precision height, energy are 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.
The present invention is two to drive electric screw press, is to utilize impulsive force to make the equipment of workpiece deformation, and the technology applicability is strong, can be used for the 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.
The two electric screw press that drive of the present invention because of at a plurality of drive motors of gear wheel arranged around, and adopt the reinforcement output shaft, so the anti-bias load ability is strong, and is safe and reliable.
The two electric screw press that drive of the present invention adopt the transmission of multi-gear one-level, have solved the low-speed big problem, and have adapted to the driving requirement of large-scale spiral forcing press low-speed big.
In sum, the two electric screw press that drive of the present invention, simple in structure and compact, parts are few, driving-chain is short, the mechanical strength height, and force-bearing situation is good, and is easy to manufacture, easy to maintenance, cost is low, and is simple to operate, and the parts loss is little, axiality is good, and overload capacity is strong, operates steadily the forming accuracy height, the anti-bias load ability is strong, and is safe and reliable, and long service life is energy-conservation, have wide range of applications, low-speed big does not have impact to electrical network.
