Double housing planer is the large machine tool that machines at the beginning of machinery, as a result of technical limitation, the workbench of double housing planer of 50 time procrastinates move used electric machinery to enlarge machine ― to spread way of motive of dynamo ― dc continuously, cause fault rate tall, bulk big, power consumption big, technology is backward. And its working way is workbench cutting undertakes when advancement, when backing down not cutting, workbench backs down is to be the next time cutting prepares, workbench is regressive be equivalent to doing useful work, and wasteful time, because this user puts forward,transform it into planer-type milling machine. Introduce to transforming below. Transforming program is: 1. Workbench procrastinates use preservation original and mechanical reducer, increase one level again 1: Reducer of 75 worm wheel, demolish pull the 55kW direct current that uses workbench to make reciprocate so advocate electric machinery, instead 5. 5kW 4 class communicates asynchronous electric machinery, use Ai Mo to give birth to EV2000-4T0075G 7. Drive of 5kW G transducer, because workbench is ongoing rate is very slow, minutely a requirement advancement 2cm, because of this workbench advocate electric machinery power is needless very big. Increase mechanical decelerate to compare, it is to let transducer job be in 10Hz above, avoid workbench to produce phenomenon of low speed crawl, transducer power type selecting is bigger than electric machinery one class is to be electricity passes when preventing transducer low speed. Workbench cannot produce low speed to crawl is transformed crucial point. Workbench electric machinery controls a demand: With pushbutton implementation is inverting, stop machine. Frequency gives have 2 kinds of kind: 1.

But timing archives (0~50Hz) . 2.

Secure high gear: 80Hz. But the rate when timing archives lets workbench milling is adjustable, fixed high gear lets workbench not when milling can the hand moves sudden shift. But timing archives controls an implementation with far end, fixed high gear comes true with switch, the method is to use switch to close transducer X3, short receive terminal of X1, X2, switch frequency gives a passageway for VCI imitate, word of the amount to when switch disconnects is given 3 (serial mouth is given) . 2.

Dismantle the original planing tool on tool carrier of beam of double housing planer and accessory plant, head of the milling cutter on installation, perpendicular mill (be equivalent to) of reducer of a gear, the take-off drive milling cutter of head rotates, head input axis is used 7.

5kW 4 class communicates drive of asynchronous electric machinery, match EV2000 - 4T0075G transducer. Control a demand: With pushbutton implementation is inverting, stop machine, frequency controls box adjustment in far end. 3.

Crossbeam takes a knife (namely left and right sides of milling cutter level is mobile) electric machinery is formerly 3.

7kW 4 class communicates asynchronous machine, use only match an EV2000, 4T0037G transducer, like controlling means to be the same as workbench, speed gives have 2 kinds of kind: 1.

Far end controls a box serial mouth is given (0~50Hz) , 2.

Switch puts through fixed 80Hz is given, the method also is to use switch to close transducer X3, short receive terminal of X1, X2, switch frequency gives a passageway for VCI imitate, word of the amount to when switch disconnects is given 3 (serial mouth is given) . Specific parameter: F7.

00=22, F7.

01=23, F7.

03=24. VCI imitate is given here is to use line weak point to receive transducer terminal VRF and VCI, be equivalent to VCI=10V maximum, pass set F0.

05=80Hz, F0.

12=80Hz, F1.

07=80Hz implementation switch puts through give 80Hz. 4.

Electric machinery of side mill head is 7.

5kW 4 class communicates asynchronous electric machinery, match EV2000 - 4T0075G transducer. Use terminal to give implementation to inverting, use far end only Control Panel changes frequency, control just the same with perpendicular mill head. Far end the R485 bus line of Control Panel is linked together with terminal of all transducer R485, the frequency set of all transducer can pass Control Panel of You Yuanduan of serial communication means to adjust, simplified to control route. 5.

The last the problem that should solve is crossbeam rises fall to be controlled with clamp, also be place of transformed a key. The modular bridge of dragon door dig should make perpendicular fluctuation move according to the discretion of workpiece, it by 1.

Drive of electric machinery of asynchronous of communication of 5kW 4 class is perpendicular filar lever is rotational, crossbeam rises fall electric machinery is turning make crossbeam rises, crossbeam rises fall electric machinery inverts make crossbeam drops. And there still is unit of a mechanical clamp on crossbeam, by 0.

75kW communicates drive of asynchronous electric machinery, in crossbeam section bundle after moving up and down, clamp electric machinery is turning, on the orbit that makes the clamp pressing plate of clamp device is pressed on crossbeam to play sport closely, when making crossbeam is processing work, won't move up and down, assure the precision of treatment thereby. Want to make clamp electric machinery inverts ahead of schedule when crossbeam makes fluctuation move, after loose clamp pressing plate, crossbeam ability moves up and down. With switch of double contact journey detects position of clamp pressing plate, after impaction of clamp pressing plate reachs the designated position, of journey switch often shut contact FSK to close, often often open contact JXK, loose when reaching the designated position, often shut contact FSK to disconnect, often open contact JXK to close. Still have a detail: Drop when crossbeam when the end, while clamp electric machinery is turning, crossbeam rises fall electric machinery also is turning 1~2 second, let crossbeam rise one bit, next crossbeam clamp. The purpose is to eliminate crossbeam to rise fall the clearance of filar lever. The action of SJ time relay lets crossbeam ascendant backdate namely a few seconds, the contact after asking its movement is electrify closes, delay time of the contact after cutting off the power disconnects. Whole beam movement rises only and drop two pushbutton, crossbeam clamp and loosen do not need pushbutton, it is finished automatically by circuit. Crossbeam rises fall to did not use transducer control with clamp electric machinery. Next graphs are circuit of control of a typical beam. Summary: Because use Ai Mo to give birth to EV2000 series transducer, through terminal quick switch frequency gives a passageway, realized serial communication frequency is given and terminal VCI fixed frequency is given, went to the lavatory to operate, use far end Control Panel increased interference rejection capacity.

Simplified circuit, because transducer has overload to fall automatically frequency function, workbench electric machinery and head electric machinery never appear overload stops machine phenomenon, dependability increases greatly. CNC Milling CNC Machining
