5 Qhov yuam kev kom zam thaum Customizing U Shaped Neodymium Magnets

U-shaped neodymium hlau nplaum yog lub zog hluav taws xob. Lawv cov qauv tsim tshwj xeeb tsom rau qhov muaj zog sib nqus hauv qhov chaw sib txuam, ua rau lawv zoo tagnrho rau kev thov xws li cov hlau nplaum chucks, tshwj xeeb sensors, high-torque motors, thiab rugged fixtures. Txawm li cas los xij, lawv cov kev ua tau zoo thiab cov duab nyuaj kuj ua rau lawv nyuaj rau kev kho. Ib qho yuam kev ib zaug tuaj yeem ua rau cov nyiaj nkim, qhov project qeeb, lossis txawm tias ua tsis tiav txaus ntshai.

 

Zam 5 qhov yuam kev tseem ceeb no kom ntseeg tau tias koj cov hlau nplaum U-shaped neodymium ua tau zoo thiab nyab xeeb:

 

Qhov yuam kev #1: Tsis quav ntsej cov khoom brittleness thiab cov ntsiab lus kev ntxhov siab

 

Teeb meem:Cov hlau nplaum neodymium (tshwj xeeb tshaj yog cov qib muaj zog zoo li N52) yog qhov muaj zog, zoo li cov plooj (porcelain). Lub kaum ntse ntse ntawm U-puab tsim cov ntsiab lus kev ntxhov siab ntuj. Kev ua tsis tiav rau qhov brittleness thaum qhia qhov ntev, qhov ntev, kev ua siab ntev, lossis kev tuav yuav tuaj yeem ua rau tawg lossis tawg puas tsuaj thaum lub sijhawm tsim khoom, kev sib nqus, kev xa khoom, thiab txawm tias kev teeb tsa.

Kev daws:

Qhia Txog Loj Radius:Xav tau qhov loj tshaj plaws hauv kaum lub vojvoog (R) koj tus qauv tsim tuaj yeem ua tau. Tight 90-degree khoov yog qhov tsis muaj.

Xaiv qib zoo:Qee zaum qis dua me ntsis (piv txwv li, N42 es tsis yog N52) tuaj yeem muab cov pob txha tawv zoo dua yam tsis muaj lub zog xav tau ntau dhau.

Sib txuas lus tuav xav tau:Xyuas kom koj cov neeg tsim khoom nkag siab tias cov hlau nplaum yuav ua li cas thiab mounted. Tej zaum lawv yuav pom zoo kom ntim cov khoom tiv thaiv lossis tuav cov khoom siv.

Tsis txhob nyias ob txhais ceg:Cov ceg uas nyias dhau los ntawm qhov loj thiab lub zog ntawm cov hlau nplaum tuaj yeem ua rau muaj kev pheej hmoo ntawm pob txha.

 

Qhov yuam kev # 2: Tsim yam tsis xav txog kev taw qhia magnetization

 

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

Kev daws:

Tham ntxov:Sib tham txog koj tus qauv tsim nrog cov chaw tsim khoom hlau nplaum ua ntej ua tiav nws. Thiab nug txog magnetizing fixture cov cai thiab cov kev txwv.

Ua qhov tseem ceeb ntawm tus ncej ntsej muag nkag mus tau yooj yim:Xyuas kom tus tsim tso cai rau kom pom tseeb, tsis muaj kev nkag mus ntawm cov hlau nplaum coil mus rau tag nrho saum npoo ntawm txhua tus ncej kawg.

Nkag siab txog kev taw qhia:Kom meej meej qhia qhov xav tau magnetization orientation (axially los ntawm tus ncej) hauv koj cov specifications.

 

Qhov yuam kev # 3: Kev kwv yees qhov tseem ceeb ntawm kev ua siab ntev (los yog teeb tsa lawv nruj heev)

 

Teeb meem:Sintered Nd hlau nplaum shrink thaum lub sij hawm tsim khoom, ua rau tom qab sintering machining nyuaj thiab txaus ntshai (saib yuam kev #1!). Cia siab tias "machined hlau" kam rau ua (± 0.001 in.) yog qhov tsis muaj tseeb thiab tsis tshua muaj nqi. Hloov pauv, kev qhia qhov ntev dhau lawm (± 0.1 in.) yuav ua rau cov hlau nplaum tsis tuaj yeem siv hauv koj lub rooj sib txoos.

Kev daws:

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

Ua pragmatic:Qhia kom nruj nruj tsuas yog qhov uas lawv tseem ceeb heev rau kev ua haujlwm, xws li mating nto. Hauv lwm qhov xwm txheej, qhov kev cia siab qis dua tuaj yeem txuag cov nqi thiab txo kev pheej hmoo.

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

 

Qhov yuam kev # 4: Tsis quav ntsej txog kev tiv thaiv ib puag ncig (coatings)

Teeb meem:Cov hlau nplaum neodymium liab qab corrode sai sai thaum raug cov dej noo, av noo, lossis qee yam tshuaj. Corrosion pib ntawm qhov chaw tsis muaj zog sab hauv thiab sai sai degrades magnetic kev ua tau zoo thiab cov qauv kev ncaj ncees. Xaiv cov txheej txheej tsis raug, lossis xav tias cov txheej txheem txheej txheem tsim nyog rau qhov chaw hnyav, tuaj yeem ua rau ua tsis tiav ntxov.

Kev daws:

Tsis txhob tsis quav ntsej cov coatings:Bare NdFeB tsis haum rau cov hlau nplaum ua haujlwm.

Coatings yuav tsum sib haum rau ib puag ncig:Txheem nickel-tooj ​​liab-nickel (Ni-Cu-Ni) plating yog tsim rau feem ntau siv sab hauv tsev. Rau ib puag ncig uas ntub dej, ntub dej, sab nraum zoov, lossis raug tshuaj lom neeg, qhia cov txheej txheem rugged xws li:

Epoxy / Parylene:Zoo noo noo thiab tshuaj tiv thaiv, thiab hluav taws xob rwb thaiv tsev.

Kub los yog zinc:rau kev tiv thaiv corrosion.

Epoxy tuab:rau ib puag ncig hnyav.

Qhia kom meej hauv kaum kev pab them nqi:Ua kom pom tseeb tias cov txheej yuav tsum tau muab kev tiv thaiv zoo ib yam, tshwj xeeb tshaj yog nyob rau hauv kev ntxhov siab hauv cov ces kaum ntawm U-puab. Nug txog lawv kev ua haujlwm lav.

Xav txog kev kuaj ntsev ntsev:Yog tias muaj kev tiv thaiv corrosion tseem ceeb, qhia cov naj npawb ntawm cov xuab moos ntawm kev ntsuas ntsev ntsev (xws li ASTM B117) uas cov hlau nplaum coated yuav tsum dhau.

 

Yuam kev #5: Hla lub Prototype Theem

Teeb meem:Muaj kev pheej hmoo hauv kev dhia mus rau hauv qhov kev txiav txim loj raws li CAD qauv lossis cov ntaub ntawv ib leeg. Cov yam tseem ceeb hauv ntiaj teb xws li kev sib nqus rub tawm, qhov sib haum ntawm cov khoom, tuav tsis muaj zog, lossis kev sib cuam tshuam uas tsis tau pom dua tsuas yog pom meej nrog cov qauv ntawm lub cev.

 

Kev daws:

Ua prototypes xaj: pob nyiaj siv thiab hais kom me me ntawm cov qauv ua ntej.

Kuaj nruj: Kawm cov qauv rau cov xwm txheej hauv ntiaj teb tiag:

Xyuas kom haum thiab functionality nyob rau hauv lub rooj sib txoos.

Kev ntsuas lub ntiaj teb tiag tiag (nws puas ua tau raws li koj xav tau?).

Kev ntsuas ntsuas (nws puas yuav muaj sia nyob nruab?).

Environmental exposure tests (yog muaj).

Iterate raws li qhov xav tau: Siv cov lus tawm tswv yim los ua kom zoo dua qhov ntev, kam rau ua, txheej, lossis qib ua ntej cog lus rau kev tsim khoom kim.
