Zolakwa 5 Zoyenera Kupewa Mukamakonza Maginito Opangidwa ndi Neodymium

Maginito a neodymium ooneka ngati U ndi mphamvu. Kapangidwe kake kapadera kamayang'ana mphamvu ya maginito yamphamvu kwambiri pamalo ophatikizika, kuwapangitsa kukhala oyenera kugwiritsa ntchito zinthu zambiri monga maginito chuck, masensa apadera, ma mota a torque yayikulu, ndi zida zolimba. Komabe, machitidwe awo amphamvu ndi mawonekedwe ovuta amawapangitsanso kukhala ovuta kuwasintha. Kulakwitsa kamodzi kungayambitse kuwononga ndalama, kuchedwa kwa ntchito, kapena kulephera koopsa.

 

Pewani zolakwika 5 izi kuti muwonetsetse kuti maginito anu a neodymium okhala ngati U-amachita bwino komanso mosatekeseka:

 

Cholakwika #1: Kunyalanyaza Kuwonongeka Kwazinthu ndi Kupsinjika Maganizo

 

Vuto:Maginito a Neodymium (makamaka magiredi amphamvu kwambiri ngati N52) amakhala osalimba, ngati zadothi. Makona akuthwa a mawonekedwe a U amapanga malo okhazikika achilengedwe. Kulephera kuwerengera za kuphulika uku pofotokoza kukula, kulolerana, kapena zofunikira zogwirira ntchito kungayambitse ming'alu kapena kusweka koopsa panthawi yopanga, maginito, kutumiza, ngakhale kuyika.

Yankho:

Tchulani Radius Yaikulu:Pamafunika utali wokulirapo wamkati mwa ngodya (R) kapangidwe kanu kangagwire. Kupindika kolimba kwa ma degree 90 ndikopanda-ayi.

Sankhani giredi yoyenera:Nthawi zina giredi yotsika pang'ono (mwachitsanzo, N42 m'malo mwa N52) imatha kupereka kulimba kwapang'onopang'ono popanda kupereka mphamvu zochulukirapo.

Lumikizanani ndi zofunika:Onetsetsani kuti wopanga wanu akumvetsetsa momwe maginito angagwiritsire ntchito ndikuyika. Angalimbikitse kuyika zodzitchinjiriza kapena zowongolera.

Pewani miyendo yopyapyala:Miyendo yomwe imakhala yopyapyala kwambiri poyerekeza ndi kukula ndi mphamvu ya maginito imatha kuonjezera ngozi yosweka.

 

Cholakwika #2: Kupanga osaganizira momwe maginito amayendera

 

Vuto:Maginito a NdFeB amapeza mphamvu zawo kuchokera ku magnetizing m'njira inayake pambuyo pa sintering. Kwa maginito opangidwa ndi U, mitengoyo imakhala kumapeto kwa miyendo. Ngati mungatchule mawonekedwe ovuta kapena kukula komwe kumalepheretsa mawonekedwe a magnetizing kuti agwirizane bwino ndi nkhope za mzati, maginito sangafikire mphamvu zake zazikulu za magnetization kapena zingayambitse zolakwika za magnetization.

Yankho:

Funsani msanga:Kambiranani kapangidwe kanu ndi wopanga maginito musanamalize. Ndipo funsani za magnetizing fixture zofunika ndi zolephera.

Ikani patsogolo kupezeka kwa nkhope:Onetsetsani kuti kapangidwe kake kamalola kuti koyilo ya magnetizing ikhale yowoneka bwino, yopanda chotchinga pamwamba pa malekezero aliwonse.

Kumvetsetsa kolowera:Nenani momveka bwino momwe mumafunira maginito (axially kupyola pamtengo) muzofotokozera zanu.

 

Cholakwika #3: Kuchepetsa kufunikira kwa kulolerana (kapena kuwakhazikitsa mwamphamvu kwambiri)

 

Vuto:Maginito a Sintered Nd amachepa panthawi yopanga, kupangitsa makina a post-sintering kukhala ovuta komanso owopsa (onani Kulakwitsa #1!). Kuyembekezera kulolerana kwa "zitsulo zamakina" (± 0.001 in.) sizowona komanso zokwera mtengo kwambiri. Mosiyana ndi zimenezi, kutchula kulolerana kwakukulu (± 0.1 in.) kungapangitse maginito omwe sangathe kugwiritsidwa ntchito pagulu lanu.

Yankho:

Mvetsetsani miyezo yamakampani:Kumvetsetsa kulekerera kwa "sintered" kwa maginito a NdFeB (nthawi zambiri ± 0.3% mpaka ± 0.5% ya kukula, ndi kulolerana kochepa kumakhala ± 0.1 mm kapena ± 0.005 mu.).

Khalani pragmatic:Tchulani kulolerana kolimba kokha komwe kuli kofunikira kuti agwire ntchito, monga malo okwerera. Nthawi zina, kulolerana kochepa kumatha kupulumutsa ndalama ndikuchepetsa chiopsezo.

Kambiranani za akupera:Ngati pamwamba payenera kukhala yolondola kwambiri (mwachitsanzo, nkhope ya chuck), tchulani kuti kugaya ndikofunikira. Izi zikhoza kuwonjezera mtengo ndi chiopsezo chachikulu, choncho chigwiritseni ntchito pokhapokha pakufunika. Onetsetsani kuti wopanga akudziwa malo omwe amafunikira kugaya.

 

Cholakwika #4: Kunyalanyaza chitetezo cha chilengedwe (zokutira)

Vuto:Maginito a Bare neodymium amawononga msanga akakumana ndi chinyezi, chinyezi, kapena mankhwala ena. Kuwonongeka kumayambira m'makona amkati omwe ali pachiwopsezo ndipo amawononga msanga magwiridwe antchito a maginito komanso kusakhazikika kwamapangidwe. Kusankha zokutira kolakwika, kapena kuganiza kuti zokutira zokhazikika ndizokwanira malo ovuta, kungayambitse kulephera msanga.

Yankho:

Osanyalanyaza zokutira:Bare NdFeB si oyenera maginito zinchito.

Zovala ziyenera kufanana ndi chilengedwe:Kuyika kwa nickel-copper-nickel (Ni-Cu-Ni) ndikoyenera kugwiritsidwa ntchito m'nyumba zambiri. Kwa malo omwe ali ndi chinyontho, chonyowa, panja, kapena opangidwa ndi mankhwala, tchulani zokutira zolimba monga:

Epoxy/Parylene:Wabwino chinyezi ndi kukana mankhwala, ndi kutchinjiriza magetsi.

Golide kapena zinki:kwa kukana dzimbiri kwapadera.

Epoxy wandiweyani:kwa malo ovuta.

Tchulani zomwe zili mkati mwakona:Tsindikani kuti chophimbacho chiyenera kupereka kuphimba kofanana, makamaka pazovuta kwambiri mkati mwa ngodya za U-mawonekedwe. Funsani za chitsimikizo cha ntchito yawo.

Lingalirani kuyezetsa kutsitsi kwa mchere:Ngati kukana dzimbiri kuli kofunikira, tchulani kuchuluka kwa maola akuyezetsa kupopera mchere (mwachitsanzo, ASTM B117) kuti maginito wokutidwa ayenera kudutsa.

 

Cholakwika #5: Kudumpha Gawo la Prototype

Vuto:Pali zowopsa pakudumphira mu dongosolo lalikulu kutengera mtundu wa CAD kapena deta yokha. Zinthu zenizeni padziko lapansi monga kugawa maginito, kukwanira kwenikweni kwa zigawo, kusalimba, kapena kuyanjana kosayembekezereka kungawonekere ndi zitsanzo zenizeni.

 

Yankho:

Konzani ma prototypes: bajeti ndikuumirira pagulu laling'ono la ma prototypes poyamba.

Yesani mwamphamvu: fotokozani za zochitika zenizeni zapadziko lapansi:

Onetsetsani kuti mukugwira ntchito ndikuchita bwino mu msonkhano.

Miyezo yeniyeni yokoka (kodi imakwaniritsa zosowa zanu?).

Kuyesa mayeso (kodi kupulumuka kukhazikitsidwa?).

Mayeso okhudzana ndi chilengedwe (ngati kuli kotheka).

Bweretsani momwe mukufunikira: Gwiritsani ntchito ndemanga zachitsanzo kuti muwongolere kukula, zololera, zokutira, kapena magiredi musanapange kupanga zodula.
