Iimpazamo ezi-5 onokuziphepha xa uLungisa iiMazibuthe zeNeodymium ezibunjwe ngokwezifiso

Imagnethi emile okwe-neodymium yindlu yamandla. Uyilo lwazo olwahlukileyo lugxile kumhlaba wemagnethi owomeleleyo kwindawo exineneyo, nto leyo ebenza ukuba bafanelekele usetyenziso olufunwayo olunje ngee-chucks zemagnethi, izinzwa ezikhethekileyo, iimotor ezinetorque ephezulu, kunye nokulungiswa kwamagingxigingxi. Nangona kunjalo, ukusebenza kwabo okunamandla kunye nokumila okuntsokothileyo kwenza kube nzima ukwenza ngokwezifiso. Impazamo enye inokukhokelela kwinkcitho yemali, ukulibaziseka kweprojekthi, okanye ukusilela okuyingozi.

 

Ziphephe ezi mpazamo zi-5 zibalulekileyo zokuqinisekisa ukuba iimagnethi zakho ze-U-shaped neodymium zisebenza ngokugqibeleleyo nangokukhuselekileyo:

 

I-Mistake #1: Ukungahoywa kwezinto eziphathekayo kunye namanqaku oxinzelelo

 

Ingxaki:Imagnethi ye-Neodymium (ingakumbi awona mabanga ayomeleleyo afana ne-N52) i-brittle ngokwendalo, njengeporcelain entle. Iikona ezibukhali ze-U-shape zidala amanqaku oxinzelelo lwendalo. Ukungaphumeleli ukunika ingxelo ngobu brittleness xa uchaza imilinganiselo, ukunyamezela, okanye iimfuno zokuphatha kunokukhokelela kwiintanda okanye iifractures eziyingozi ngexesha lokwenziwa, ukwenza imagneti, ukuthumela, kunye nofakelo.

Isisombululo:

Chaza iRadius enkulu:Ifuna eyona ndawo inkulu ngaphakathi kwikona yeradiyasi (R) uyilo lwakho lunokusingatha. Ukugoba okuqinileyo kwe-90-degree akukho-hayi.

Khetha ibakala elifanelekileyo:Ngamanye amaxesha ibakala elisezantsi kancinane (umz., N42 endaweni ye-N52) linokubonelela ngokuqina kokwaphuka ngaphandle kokuncama amandla amaninzi afunekayo.

Nxibelelana ngeemfuno zokuphatha:Qinisekisa ukuba umenzi wakho uyayiqonda indlela iimagnethi eziya kuphathwa kwaye zixhonywe ngayo. Basenokuncoma ukupakishwa kokukhusela okanye ukuphatha izixhobo.

Yiphephe imilenze emincinci:Imilenze emincinci kakhulu xa kuthelekiswa nobukhulu kunye namandla emagnethi inokunyusa kakhulu umngcipheko wokwaphuka.

 

Impazamo #2: Ukuyila ngaphandle kokuqwalasela umkhombandlela wemagnetization

 

Ingxaki:Iimagnethi ze-NdFeB zifumana amandla azo kwi-magnetizing kwicala elithile emva kokuntywila. Kwimagnethi ene-U, izibonda ziphantse zihlala ekupheleni kwemilenze. Ukuba ukhankanya imilo entsonkothileyo okanye ubungakanani obunqanda ukulungiswa kwemagneti ekunxibelelaneni ngokufanelekileyo nobuso bepali, umazibuthe akazukufikelela kumandla ayo aphezulu okanye angabangela iimpazamo zemagneti.

Isisombululo:

Thetha kwangethuba:Xoxa ngoyilo lwakho nomenzi wemagnethi phambi kokuba ugqibezele. Kwaye ubuze malunga neemfuneko zemagnetizing fixture kunye nemida.

Beka phambili ukufikeleleka kobuso bepali:Qinisekisa ukuba uyilo luvumela ukufikelela okucacileyo, okungathintelwanga kwekhoyili yemagnethi kuwo wonke umphezulu wepali nganye ekupheleni.

Qonda uqhelaniso:Chaza ngokucacileyo i-orientation efunwayo yemagneti (i-axially ngepali) kwiinkcukacha zakho.

 

Impazamo #3: Ukujongela phantsi ukubaluleka kokunyamezelana (okanye ukukumisa kuqine kakhulu)

 

Ingxaki:Iimagnethi ze-Sintered Nd ziyancipha ngexesha lenkqubo yokuvelisa, okwenza ukuba i-post-sintering machining ibe nzima kwaye iyingozi (jonga i-Mistake #1!). Ukulindela ukunyamezelwa kwe "metal'ed metal" (± 0.001 in.) akuyonyani kwaye kubiza kakhulu. Ngokuchaseneyo, ukucacisa ukunyamezela kubanzi kakhulu (±0.1 in.) kunokubangela umazibuthe ongenakusetyenziswa kwindibano yakho.

Isisombululo:

Qonda imigangatho yoshishino:Qonda unyamezelo oluqhelekileyo “lwe-sintered” kwiimagnethi ze-NdFeB (ngokwesiqhelo ±0.3% ukuya ku-±0.5% yobungakanani, kunye nokunyamezelana okuncinci okuqhelekileyo ± 0.1 mm okanye ± 0.005 ngaphakathi.).

Yiba pragmatic:Cacisa ukunyamezelana okuqinileyo kuphela apho kubaluleke kakhulu ukusebenza, njengendawo yokukhwelana. Kwezinye iimeko, ukunyamezela okuphantsi kunokugcina iindleko kunye nokunciphisa umngcipheko.

Xoxa ngokusila:Ukuba umphezulu kufuneka uchaneke kakhulu (umzekelo, ubuso be-chuck), cacisa ukuba kuyafuneka ukucola. Oku kunokongeza iindleko ezibalulekileyo kunye nomngcipheko, ngoko sebenzisa kuphela xa kuyimfuneko. Qinisekisa ukuba umenzi uyazi ukuba yeyiphi imiphezulu efuna ukusila.

 

Impazamo #4: Ukungahoyi ukhuseleko lwendalo esingqongileyo (iingubo)

Ingxaki:Iimagnethi ezingenanto ze-neodymium zidla ngokukhawuleza xa zisesichengeni sokufuma, ukufuma, okanye iikhemikhali ezithile. I-Corrosion iqala kwiikona zangaphakathi ezisesichengeni kwaye ngokukhawuleza ithobisa ukusebenza kwamagnetic kunye nokunyaniseka kwesakhiwo. Ukukhetha i-coating engafanelekanga, okanye ukucinga ukuba i-coating standard ifanelekile kwiimeko ezinzima, kunokukhokelela ekungaphumeleli kwangaphambi kwexesha.

Isisombululo:

Ungaze uzihoye iingubo:I-Bare NdFeB ayifanelekanga kwiimagnethi ezisebenzayo.

Iingubo kufuneka zihambelane nokusingqongileyo:I-nickel-copper-nickel eqhelekileyo (i-Ni-Cu-Ni) i-plating ifanelekile kusetyenziso oluninzi lwangaphakathi. Kwiimeko-bume ezimanzi, ezimanzi, ngaphandle, okanye ezivezwe kwimichiza, khankanya isambatho esirhabaxa esinje:

I-Epoxy/Parylene:Ukufuma okugqwesileyo kunye nokumelana neekhemikhali, kunye nokufakelwa kombane.

Igolide okanye i-zinc:kuxhathiso oluthile lokutya.

I-epoxy engqindilili:kwindawo ezinzima.

Cacisa ngaphakathi kwikona egubungelayo:Gxininisa ukuba i-coating kufuneka ibonelele nge-uniform coverage, ngokukodwa kwi-high-stress-stress in the corner of a U-shape. Buza ngesiqinisekiso sokusebenza kwabo.

Qwalasela uvavanyo lwesitshizi setyuwa:Ukuba ukuxhathisa kokumhlwa kubalulekile, chaza inani leeyure zovavanyo lwesitshizi setyuwa (umzekelo, i-ASTM B117) ekufuneka idlule umazibuthe ogqunyiweyo.

 

Impazamo #5: Ukutsiba iSigaba sePrototype

Ingxaki:Kukho imingcipheko ekutsibeni kwi-odolo enkulu esekelwe kwimodeli ye-CAD okanye i-database yodwa. Imiba yelizwe lokwenyani efana nokusasazwa kotsalo lwemagnethi, ukufaneleka kwamalungu, ukuphatha fragility, okanye ukusebenzisana okungalindelekanga kunokubonakala kuphela ngesampulu yomzimba.

 

Isisombululo:

Yenza ulandelelwano lweeprototypes: uhlahlo lwabiwo-mali kwaye ugxininise kwibhetshi encinci yeeprototypes kuqala.

Vavanya ngokungqongqo: Iiprototypes zesifundo kwiimeko zehlabathi lokwenyani:

Qinisekisa ukufaneleka kunye nokusebenza kwindibano.

Imilinganiselo yokwenyani yokutsalwa kwehlabathi (ngaba iyahlangabezana neemfuno zakho?).

Ukuphatha iimvavanyo (ngaba kuya kusinda ukufakela?).

Uvavanyo lokuvezwa kokusingqongileyo (ukuba lukhona).

Phinda kwakhona njengoko kufuneka: Sebenzisa ingxelo yeprototype ukwandisa ubukhulu, ukunyamezela, ukugquma, okanye amabakala ngaphambi kokuba uzinikele kwimveliso enexabiso eliphezulu.
