Bayan Fage: Yadda U Siffar Neodymium Magnets Aka Kera

A cikin masana'antu inda ƙarfin maganadisu, mai da hankali kan jagora, da ƙirar ƙira ba su da alaƙa,Neodymium maganadiso U-dimbin yawatsaya a matsayin jarumai marasa waƙa. Amma ta yaya aka haifi waɗannan maɗaukaki masu ƙarfi, siffa ta musamman? Tafiya daga ɗanyen foda zuwa babban doki na maganadisu wani nau'in kimiyyar kayan aiki ne, matsananciyar injiniyanci, da ingantaccen kulawar inganci. Mu shiga cikin falon masana'anta.

Raw Materials: Gidauniyar

Duk yana farawa da "NdFeB" triad:

• Neodymium (Nd): Tauraron abubuwan da ba kasafai ba, yana ba da damar ƙarfin maganadisu mara misaltuwa.
• Iron (Fe): Kashin bayan tsarin.
• Boron (B): The stabilizer, inganta tilastawa (juriya ga demagnetization).

Waɗannan abubuwan suna gauraye, narke, kuma da sauri a sanyaya su cikin flakes, sa'an nan kuma a niƙa su cikin lallausan foda mai girman micron. Mahimmanci, foda dole ne ya zama mara amfani da iskar oxygen (wanda aka sarrafa shi a cikin iskar gas mara amfani) don hana iskar oxygen da ke gurgunta aikin maganadisu.

Mataki na 1: Latsa - Siffata Gaba

Ana ɗora foda a cikin ƙira. Don maganadisu mai siffar U, hanyoyin latsawa biyu sun mamaye:

1. Latsa Istatic:
   • An lullube foda a cikin m m.
   • Wanda ke ƙarƙashin matsa lamba mai ƙarfi na hydraulic (10,000+ PSI) daga kowane kwatance.
   • Yana samar da ɓangarorin kusa-net-net tare da yawa iri ɗaya da daidaitawar maganadisu.
2. Latsa maɓalli:
   • Filin maganadisu yana daidaita barbashilokacindannawa.
   • Mahimmanci don haɓaka samfurin makamashi na maganadisu(BH) maxtare da sandunan U.

Me ya sa yake da mahimmanci: Daidaiton ɓarna yana ƙayyade ƙarfin jagorar maganadisu - U-magnet da ba daidai ba ya rasa> 30% inganci.

Mataki 2: Sintering - The "Bonding Wuta"

Sassan "kore" da aka danna suna shiga tanderun wuta:

• Mai zafi zuwa ≈1080C (kusa da wurin narkewa) na sa'o'i.
• Barbashi suna haɗawa cikin ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan microstructure.
• Sannun makullin sanyaya a cikin tsarin crystalline.

Kalubalen: U-siffai suna da wuyar samun warping saboda rashin daidaituwa na rarraba taro. Ƙirar ƙayyadaddun ƙayyadaddun ƙayyadaddun yanayin zafi suna da mahimmanci don kiyaye kwanciyar hankali.

Mataki na 3: Injin Injiniya - Madaidaici a kowace Lanƙwasa

Sintered NdFeB ba ta da ƙarfi (kamar yumbu). Siffata U na buƙatar ƙwarewar kayan aikin lu'u-lu'u:

• Niƙa: ƙafafun lu'u-lu'u masu lu'u-lu'u suna yanke lanƙwasa na ciki da ƙafafu na waje zuwa haƙuri na ± 0.05 mm.
• Waya EDM: Don hadaddun bayanan bayanan U, wayar da aka caje tana yin vaporized abu tare da daidaiton micron.
• Chamfering: Duk gefuna suna santsi don hana guntuwa da tattara hankalin maganadisu.

Gaskiya mai daɗi: NdFeB niƙa sludge ne sosai flammable! Tsarukan sanyaya suna hana tartsatsin wuta da kama barbashi don sake amfani da su.

Mataki na 4: Lankwasawa - Lokacin da Magnets Haɗu da Origami

Madadin hanya don manyan U-magnets:

1. Tubalan na rectangular suna karkatar da ƙasa.
2. Mai zafi zuwa ≈200C (kasa da zafin jiki na Curie).
3. Lankwasa ruwa a cikin "U" da madaidaicin ya mutu.

The Art: Yayi sauri = fasa. Yayi sanyi sosai = karaya. Zazzabi, matsa lamba, da radius lanƙwasa dole ne su daidaita don guje wa ƙananan karaya waɗanda ke raunana maganadisu.

Mataki na 5: Rufi - Armor

Bare NdFeB yana lalata da sauri. Rufe ba abin tattaunawa ba ne:

• Electroplating: Nickel-Copper-nickel (Ni-Cu-Ni) yadudduka uku suna ba da juriya mai ƙarfi.
• Epoxy/Parylene: Don aikace-aikacen likita/muhalli inda aka hana ions karfe.
• Musamman: Zinariya (electronics), Zinc (mai tsada).

Kalubalen U-Siffa: Rufe madaidaicin lankwasa na ciki yana buƙatar ƙwararrun gyare-gyaren ganga ko tsarin feshin mutum-mutumi.

Mataki na 6: Magnetizing - "Farkawa"

Magnet ɗin yana samun ƙarfinsa na ƙarshe, yana guje wa lalacewa yayin sarrafawa:

• Sanya tsakanin manyan coils masu sarrafa capacitor.
• An ƙaddamar da filin wasa> 30,000 Oe (3 Tesla) na millise seconds.
• An saita alkiblar filin daidai gwargwado zuwa gindin U, tana daidaita sanduna a tukwici.

Maɓalli mai mahimmanciU-magnets sau da yawa suna buƙatar maganadisu da yawa (misali, madaidaicin sanduna a fadin fuskar ciki) don amfani da firikwensin/mota.

Mataki na 7: Gudanar da Inganci - Bayan Gauss Mita

Kowane U-magnet yana fuskantar gwaji mara tausayi:

1. Gaussmeter/Fluxmeter: Yana auna filin saman & yawan juzu'i.
2. Injin Ma'auni na Haɗawa (CMM): Yana tabbatar da daidaiton matakan ƙananan matakan.
3. Gwajin Fasa Gishiri: Yana tabbatar da dorewar shafi (misali, juriya 48-500+).
4. Gwaje-gwajen Ja: Don riƙe maganadisu, yana tabbatar da ƙarfin mannewa.
5. Analysis Curve Demagnetization: Tabbatar da (BH) max, Hci, HcJ.

Lalacewar? Ko da 2% karkacewa yana nufin kin amincewa. U-siffai suna buƙatar kamala.
