Tom Qab Qhov Xwm Txheej: Yuav Ua Li Cas Tsim Cov Hlau Nkaus Neodymium Uas Zoo Li U

Hauv cov lag luam uas lub zog sib nqus, kev tsom mus rau kev taw qhia, thiab kev tsim qauv me me tsis tuaj yeem sib tham tau,Cov hlau nplaum neodymium zoo li Usawv ua cov phab ej uas tsis muaj leej twg paub. Tiam sis cov hlau nplaum muaj zog thiab zoo li no yug los li cas? Txoj kev taug kev los ntawm hmoov nyoos mus rau lub zog ua haujlwm siab yog ib qho kev ua tiav ntawm kev tshawb fawb txog cov ntaub ntawv, kev tsim kho kom zoo heev, thiab kev tswj xyuas zoo. Cia peb nkag mus rau hauv pem teb Hoobkas.

Cov Khoom Siv Raw: Lub Hauv Paus

Txhua yam pib nrog "NdFeB" triad:

• Neodymium (Nd): Lub hnub qub ntawm cov khoom tsis tshua muaj ntiaj teb, ua rau muaj zog sib nqus tsis sib xws.
• Hlau (Fe): Lub hauv paus ntawm cov qauv.
• Boron (B): Tus stabilizer, txhim kho coercivity (tsis kam rau demagnetization).

Cov khoom no raug sib xyaw ua ke, yaj, thiab txias sai sai ua cov nplais, tom qab ntawd zom ua hmoov me me, me me li micron. Qhov tseem ceeb, cov hmoov yuav tsum tsis muaj oxygen (ua tiav hauv cov roj inert / lub tshuab nqus tsev) kom tiv thaiv kev oxidation uas ua rau lub zog sib nqus tsis zoo.

Theem 1: Kev Nias - Tsim Lub Neej Yav Tom Ntej

Cov hmoov raug muab tso rau hauv pwm. Rau cov hlau nplaum U-puab, ob txoj kev nias tseem ceeb:

1. Isostatic nias:
   • Hmoov yog qhwv rau hauv ib lub pwm uas yoog tau.
   • Raug rau lub zog hydraulic siab heev (10,000+ PSI) los ntawm txhua qhov kev taw qhia.
   • Tsim cov duab khoob ze li ntawm lub vas nrog qhov ceev sib npaug thiab sib nqus sib dhos.
2. Kev Nias Ntawm Sab Nraud:
   • Ib lub teb sib nqus sib dhos cov khoom me methaum lub sijhawmnias.
   • Tseem ceeb rau kev ua kom lub zog ntawm lub hlau nplaum siab tshaj plaws(BH) siab tshaj plawsraws cov ncej U.

Vim li cas nws thiaj tseem ceebKev sib dhos ntawm cov khoom me me txiav txim siab lub zog ntawm lub hlau nplaum - lub hlau nplaum U-hlau uas tsis sib dhos poob ntau dua 30% kev ua haujlwm.

Theem 2: Sintering - Lub "Hluav Taws Sib Txuas"

Cov khoom "ntsuab" uas nias nkag mus rau hauv lub tshuab nqus tsev sintering:

• Ua kom sov rau ≈1080 ° C (ze rau qhov melting point) rau ntau teev.
• Cov khoom me me sib xyaw ua ke rau hauv cov qauv microstructure uas ntom thiab khov kho.
• Kev txias qeeb xauv rau hauv cov qauv crystalline.

Qhov Kev Sib Tw: Cov duab U-puab feem ntau yuav nkhaus vim yog qhov sib faib tsis sib npaug. Kev tsim cov khoom siv thiab cov kab ntsuas kub kom raug yog qhov tseem ceeb rau kev tswj hwm qhov ntev.

Theem 3: Kev Siv Tshuab - Kev Ua Kom Tseeb Hauv Txhua Qhov Ncua

Sintered NdFeB yog brittle (zoo li ceramic). Kev ua kom zoo li tus U xav tau kev paub txog cov cuab yeej pob zeb diamond:

• Kev Sib Tsoo: Cov log uas muaj pob zeb diamond txiav cov nkhaus sab hauv thiab cov ceg sab nraud kom raug qhov kam rau siab ntawm ± 0.05 hli.
• Hlau EDM: Rau cov U-profiles nyuaj, cov hlau them hluav taws xob ua rau cov khoom siv vaporizes nrog qhov tseeb micron.
• Chamfering: Tag nrho cov npoo yog smoothed kom tiv thaiv chipping thiab concentrate magnetic flux.

Qhov tseeb lom zem: Cov av nplaum sib tsoo NdFeB yog cov av nplaum uas yooj yim hlawv! Cov txheej txheem txias tiv thaiv cov hluav taws xob thiab ntes cov khoom me me rau kev rov ua dua tshiab.

Theem 4: Khoov - Thaum Cov Hlau Nplaum Sib Ntsib Origami

Lwm txoj kev rau cov hlau nplaum U loj:

1. Cov blocks plaub fab yog sintered thiab av.
2. Kub rau ≈200 ° C (qis dua Curie kub).
3. Hydraulically khoov rau hauv "U" tawm tsam precision dies.

Kev Kos Duab: Sai dhau = tawg. Txias dhau = tawg. Kub, siab, thiab lub vojvoog khoov yuav tsum sib haum xeeb kom tsis txhob muaj cov pob me me uas ua rau lub hlau nplaum tsis muaj zog.

Theem 5: Txheej - Lub Armor

NdFeB liab qab xeb sai sai. Kev txheej tsis tuaj yeem sib tham tau:

• Electroplating: Nickel-tooj ​​liab-nickel (Ni-Cu-Ni) peb txheej muab kev tiv thaiv corrosion zoo.
• Epoxy/Parylene: Rau kev siv kho mob/ib puag ncig uas txwv tsis pub muaj cov hlau ions.
• Kev Tshwj Xeeb: Kub (khoom siv hluav taws xob), Zinc (pheej yig).

Kev Sib Tw U-Puab: Kev pleev xim rau sab hauv uas nruj kom sib npaug yuav tsum tau muaj kev pleev xim tshwj xeeb lossis cov tshuab tsuag robotic.

Theem 6: Magnetizing - Lub "Awakening"

Lub hlau nplaum tau txais nws lub zog kawg, zam kev puas tsuaj thaum tuav:

• Muab tso rau nruab nrab ntawm cov kauj loj loj uas tsav los ntawm capacitor.
• Raug rau lub zog pulsed> 30,000 Oe (3 Tesla) rau milliseconds.
• Kev taw qhia ntawm thaj teb yog teeb tsa perpendicular rau lub hauv paus U, sib dhos cov ncej ntawm cov ntsis.

Qhov tseem ceeb ntawm kev sib txawvCov hlau nplaum U feem ntau xav tau ntau tus ncej hlau nplaum (piv txwv li, hloov cov ncej hla lub ntsej muag sab hauv) rau kev siv sensor/motor.

Theem 7: Kev Tswj Xyuas Zoo - Dhau Gauss Meters

Txhua lub U-magnet raug kuaj xyuas tsis muaj kev ntxhov siab:

1. Gaussmeter/Fluxmeter: Ntsuas qhov chaw ntawm qhov chaw thiab qhov ceev ntawm cov kua dej.
2. Tshuab Ntsuas Kev Sib Koom Tes (CMM): Txheeb xyuas qhov tseeb ntawm qhov ntev ntawm micron.
3. Kev Ntsuas Tshuaj Tsuag Ntshav: Txheeb xyuas qhov ua tau ntev ntawm cov txheej (piv txwv li, tiv taus 48–500+ teev).
4. Kev Ntsuas Rub: Rau kev tuav cov hlau nplaum, ua pov thawj lub zog nplaum.
5. Kev Tshuaj Xyuas Kab Demagnetization: Pom zoo (BH) max, Hci, HcJ.

Qhov tsis zoo? Txawm tias yog 2% qhov sib txawv txhais tau tias yuav tsis raug lees txais. Cov duab U xav tau kev ua kom zoo tag nrho.

Vim li cas U-Shape xav tau kev ua haujlwm zoo tshaj plaws

1. Kev Nyuaj Siab Concentration: Cov khoov thiab cov ces kaum yog cov kev pheej hmoo tawg.
2. Kev Ncaj Ncees ntawm Txoj Kev Flux: Cov duab tsis sib xws ua rau qhov yuam kev sib phim loj zuj zus.
3. Kev Sib Xws ntawm Txheej: Cov kab sab hauv ntes cov npuas lossis cov pob nyias nyias.

Kev tsim cov hlau nplaum U-tsis yog tsuas yog cov khoom siv los ua kom zoo nkauj xwb - nws yogkev tswj hwmkev kawm txog lub cev."
