5 Qhov Yuam Kev Yuav Tsum Tsis Txhob Thaum Kho U Zoo Li Neodymium Magnets

Cov hlau nplaum neodymium zoo li tus U yog lub zog loj heev. Lawv txoj kev tsim tshwj xeeb ua rau lub zog sib nqus muaj zog heev hauv qhov chaw me me, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau ntau xws li cov chucks sib nqus, cov sensors tshwj xeeb, cov cav muaj zog siab, thiab cov khoom siv ruaj khov. Txawm li cas los xij, lawv cov kev ua tau zoo thiab cov duab nyuaj kuj ua rau lawv nyuaj rau kho. Ib qho yuam kev tuaj yeem ua rau cov nyiaj pov tseg, kev ncua sijhawm ntawm qhov project, lossis txawm tias kev ua tsis tiav txaus ntshai.

 

Tsis txhob ua qhov yuam kev tseem ceeb 5 no kom ntseeg tau tias koj cov hlau nplaum neodymium U-puab ua haujlwm zoo meej thiab muaj kev nyab xeeb:

 

Yuam Kev #1: Tsis quav ntsej txog qhov tawg yooj yim thiab cov ntsiab lus ntxhov siab ntawm cov khoom

 

Teeb meem:Cov hlau nplaum neodymium (tshwj xeeb tshaj yog cov qib muaj zog tshaj plaws xws li N52) yog qhov tsis ruaj khov, zoo li cov porcelain zoo. Cov ces kaum ntse ntawm U-puab tsim cov ntsiab lus ntxhov siab ntuj. Kev tsis suav nrog qhov tsis ruaj khov no thaum teev qhov ntev, kev kam rau siab, lossis kev tuav cov kev cai tuaj yeem ua rau muaj kev tawg lossis kev tawg loj heev thaum lub sijhawm tsim khoom, kev sib nqus, kev xa khoom, thiab txawm tias kev teeb tsa.

Kev daws teeb meem:

Qhia kom meej qhov Radius Loj:Xav tau lub ces kaum sab hauv loj tshaj plaws (R) uas koj tus qauv tsim tuaj yeem ua tau. Kev khoov nruj 90-degree yog qhov tsis pub ua.

Xaiv qib zoo:Qee zaum qib qis dua me ntsis (piv txwv li, N42 es tsis yog N52) tuaj yeem muab qhov tawg zoo dua yam tsis tas yuav txi lub zog ntau dhau.

Sib tham txog cov kev xav tau kev pab cuam:Xyuas kom tseeb tias koj tus neeg tsim khoom nkag siab txog yuav ua li cas tuav thiab teeb tsa cov hlau nplaum. Lawv yuav pom zoo kom ntim khoom tiv thaiv lossis cov khoom siv tuav.

Tsis txhob siv cov ceg nyias nyias:Cov ceg uas nyias dhau piv rau qhov loj thiab lub zog ntawm cov hlau nplaum tuaj yeem ua rau muaj kev pheej hmoo ntawm kev tawg.

 

Yuam Kev # 2: Tsim qauv yam tsis xav txog kev taw qhia magnetization

 

Teeb meem:Cov hlau nplaum NdFeB tau txais lawv lub zog los ntawm kev sib nqus hauv ib qho kev taw qhia tshwj xeeb tom qab sintering. Rau cov hlau nplaum U-puab, cov ncej yuav luag ib txwm nyob rau ntawm qhov kawg ntawm ob txhais ceg. Yog tias koj teev ib qho duab lossis qhov loj me uas tiv thaiv cov khoom siv sib nqus los ntawm kev sib cuag nrog cov ncej ntsej muag, cov hlau nplaum yuav tsis ncav cuag nws lub zog sib nqus siab tshaj plaws lossis yuav ua rau muaj qhov yuam kev sib nqus.

Kev daws teeb meem:

Tham nrog thaum ntxov:Tham txog koj tus qauv tsim nrog lub tuam txhab tsim hlau nplaum ua ntej ua tiav. Thiab nug txog cov kev cai thiab kev txwv ntawm cov khoom siv hlau nplaum.

Muab qhov tseem ceeb rau kev nkag mus rau ntawm lub ntsej muag ncej:Xyuas kom tus qauv tsim tso cai rau kev nkag mus rau qhov meej, tsis muaj kev cuam tshuam ntawm lub kauj magnetizing mus rau tag nrho qhov chaw ntawm txhua qhov kawg ntawm tus ncej.

To taub qhov kev taw qhia:Qhia meej txog qhov kev taw qhia magnetization xav tau (axially los ntawm tus ncej) hauv koj cov lus qhia.

 

Yuam Kev #3: Tsis quav ntsej qhov tseem ceeb ntawm kev kam rau siab (lossis teeb tsa lawv nruj dhau)

 

Teeb meem:Cov hlau nplaum Nd uas raug sintered yuav ntsws thaum lub sijhawm tsim khoom, ua rau kev ua haujlwm tom qab sintering nyuaj thiab txaus ntshai (saib Yuam Kev #1!). Kev xav tias yuav tsum muaj qhov kam rau siab "machined metal" (±0.001 in.) tsis yog qhov tseeb thiab kim heev. Ntawm qhov tod tes, kev teev qhov kam rau siab dav dhau (±0.1 in.) yuav ua rau muaj hlau nplaum uas siv tsis tau hauv koj lub rooj sib dhos.

Kev daws teeb meem:

To taub cov qauv kev lag luam:To taub qhov kev kam rau ua "sintered" rau cov hlau nplaum NdFeB (feem ntau yog ± 0.3% txog ± 0.5% ntawm qhov loj me, nrog rau qhov kev kam rau ua tsawg kawg nkaus feem ntau yog ± 0.1 hli lossis ± 0.005 nti).

Ua tib zoo xav txog tej yam uas muaj tseeb:Qhia meej txog qhov kam rau ua kom nruj tsuas yog thaum lawv tseem ceeb rau kev ua haujlwm, xws li cov nplaim sib txuas. Hauv lwm qhov xwm txheej, qhov kam rau ua qis dua tuaj yeem txuag cov nqi thiab txo qhov kev pheej hmoo.

Sib tham txog kev sib tsoo:Yog tias qhov chaw yuav tsum tau ua kom meej heev (piv txwv li, lub ntsej muag chuck), qhia meej tias yuav tsum tau sib tsoo. Qhov no tuaj yeem ntxiv tus nqi thiab kev pheej hmoo loj, yog li siv nws tsuas yog thaum tsim nyog. Xyuas kom tseeb tias lub chaw tsim khoom paub tias qhov chaw twg xav tau kev sib tsoo.

 

Yuam Kev #4: Tsis quav ntsej txog kev tiv thaiv ib puag ncig (txheej txheej)

Teeb meem:Cov hlau nplaum neodymium liab qab xeb sai sai thaum raug dej noo, av noo, lossis qee yam tshuaj lom neeg. Kev xeb pib ntawm cov ces kaum sab hauv uas tsis muaj zog thiab ua rau lub zog sib nqus thiab kev ua haujlwm ntawm cov qauv puas tsuaj sai sai. Kev xaiv cov txheej tsis raug, lossis xav tias cov txheej txheem txheem txaus rau cov chaw ib puag ncig hnyav, tuaj yeem ua rau tsis ua haujlwm ua ntej.

Kev daws teeb meem:

Tsis txhob tsis quav ntsej txog cov txheej txheem:NdFeB liab qab tsis haum rau cov hlau nplaum ua haujlwm.

Cov txheej txheem yuav tsum phim qhov chaw ib puag ncig:Cov txheej txheem nickel-tooj ​​liab-nickel (Ni-Cu-Ni) yog qhov tsim nyog rau feem ntau siv sab hauv tsev. Rau cov chaw uas ntub, ntub dej, sab nraum zoov, lossis raug tshuaj lom neeg, teev cov txheej txheem rugged xws li:

Epoxy/Parylene:Ua tau zoo heev rau cov dej noo thiab tshuaj lom neeg, thiab rwb thaiv hluav taws xob.

Kub los yog zinc:rau kev tiv thaiv corrosion tshwj xeeb.

Cov epoxy tuab:rau cov chaw ib puag ncig hnyav.

Qhia kom meej txog kev npog sab hauv ntawm lub ces kaum:Qhia meej tias cov txheej yuav tsum muab kev npog sib npaug, tshwj xeeb tshaj yog ntawm cov ces kaum sab hauv siab ntawm tus duab U. Nug txog lawv qhov kev lav phib xaub ua haujlwm.

Xav txog kev sim tshuaj tsuag ntsev:Yog tias qhov kev tiv thaiv xeb yog qhov tseem ceeb, qhia meej pes tsawg teev ntawm kev sim tshuaj tsuag ntsev (piv txwv li, ASTM B117) uas lub hlau nplaum coated yuav tsum dhau.

 

Yuam Kev #5: Tsis Tau Ua Prototype Theem

Teeb meem:Muaj kev pheej hmoo hauv kev dhia mus rau hauv kev txiav txim loj raws li tus qauv CAD lossis daim ntawv teev cov ntaub ntawv xwb. Cov yam ntxwv tiag tiag xws li kev faib tawm ntawm cov hlau nplaum, qhov sib haum ntawm cov khoom, kev tuav cov khoom tsis yooj yim, lossis kev sib cuam tshuam tsis tau xav txog tsuas yog pom tseeb nrog cov qauv lub cev.

 

Kev daws teeb meem:

Ua qhov kev txiav txim prototypes: npaj nyiaj txiag thiab hais kom ua ib pawg me me ntawm cov prototypes ua ntej.

Sim ua tib zoo: Muab cov qauv piv txwv rau cov xwm txheej tiag tiag:

Xyuas kom meej tias haum thiab ua haujlwm tau zoo hauv kev sib dhos.

Kev ntsuas rub tawm tiag tiag (nws puas ua tau raws li koj xav tau?).

Kev ntsuam xyuas kev tswj hwm (nws puas yuav muaj sia nyob rau kev teeb tsa?).

Kev ntsuam xyuas kev raug ib puag ncig (yog tias siv tau).

Rov ua dua raws li qhov xav tau: Siv cov lus tawm tswv yim prototype los txhim kho qhov ntev, kev kam rau siab, txheej, lossis qib ua ntej cog lus rau kev tsim khoom kim heev.
