Amaphutha ama-5 okufanele uwagweme lapho wenza ngokwezifiso ama-magnets e-U Shaped Neodymium

Omaginethi be-neodymium abamise okwe-U banamandla amakhulu. Umklamo wabo oyingqayizivele ugxila insimu yamagnetic enamandla kakhulu endaweni encane, okwenza kube kuhle kakhulu ekusetshenzisweni okudinga amandla njenge-magnetic chucks, izinzwa ezikhethekile, ama-motor ane-torque ephezulu, kanye nezinto eziqinile. Kodwa-ke, ukusebenza kwawo okunamandla kanye nesimo esiyinkimbinkimbi nakho kwenza kube nzima ukuwahlela ngokwezifiso. Iphutha elilodwa lingaholela emalini echithwayo, ekubambezelweni kwephrojekthi, noma ngisho nasekuhlulekeni okuyingozi.

 

Gwema lawa maphutha ama-5 abalulekile ukuqinisekisa ukuthi omaginethi bakho be-neodymium abakhiwe ngendlela ka-U basebenza kahle futhi ngokuphephile:

 

Iphutha #1: Ukungazinaki Izinto Ezithambile Nezici Zokucindezeleka

 

Inkinga:Omaginethi be-Neodymium (ikakhulukazi amagremu aqine kakhulu njenge-N52) bathambile ngokwemvelo, njenge-porcelain ecolekile. Amakhona abukhali obume be-U adala amaphuzu okugxilisa ukucindezeleka kwemvelo. Ukwehluleka ukubheka lokhu kubuthakathaka lapho kucaciswa ubukhulu, ukubekezelelana, noma izidingo zokuphatha kungaholela ekuqhekekeni noma ekuqhekekeni okubi kakhulu ngesikhathi sokukhiqiza, ukwenziwa kobumagnethi, ukuthunyelwa, ngisho nokufakwa.

Isixazululo:

Cacisa i-Radius Enkulu:Dinga irediyasi yekona yangaphakathi enkulu kakhulu (R) umklamo wakho ongayiphatha. Ukugoba okuqinile okungama-degree angu-90 akuvumelekile.

Khetha ibanga elifanele:Ngezinye izikhathi izinga eliphansi kancane (isib. i-N42 esikhundleni se-N52) linganikeza ukuqina okungcono kokuphuka ngaphandle kokulahlekelwa amandla amaningi adingekayo.

Xoxa ngezidingo zokusingatha:Qiniseka ukuthi umenzi wakho uyaqonda ukuthi omaginethi bazophathwa futhi bafakwe kanjani. Bangase batuse ukupakishwa okuvikelayo noma izinto zokuphatha.

Gwema imilenze emincane:Imilenze emincane kakhulu uma iqhathaniswa nobukhulu namandla kazibuthe ingandisa kakhulu ingozi yokuphuka.

 

Iphutha #2: Ukuklama ngaphandle kokucabangela isiqondiso se-magnetization

 

Inkinga:Omaginethi be-NdFeB bathola amandla abo ngokuzidonsela ohlangothini oluthile ngemva kokusha. Kumaginethi anomumo we-U, izigxobo cishe njalo zisemaphethelweni emilenze. Uma ucacisa isimo noma usayizi oyinkimbinkimbi ovimbela i-magnetizing fixture ukuthi ixhumane kahle nobuso bezigxobo, umaginethi ngeke afinyelele amandla awo aphezulu okuzidonsela noma angabangela amaphutha okuzidonsela.

Isixazululo:

Xhumana kusenesikhathi:Xoxa ngomklamo wakho nomkhiqizi wemagnet ngaphambi kokuwuqedela. Futhi ubuze ngezidingo kanye nemikhawulo yemishini yemagnetizing.

Beka phambili ukufinyeleleka kobuso be-pole:Qinisekisa ukuthi umklamo uvumela ukufinyelela okucacile, okungavinjelwe kwekhoyili edonsayo kuyo yonke indawo yengxenye ngayinye yesigxobo.

Qonda ukuqondiswa:Chaza ngokucacile indlela yokuma komagnetization oyifunayo (ngokuqondile ngokusebenzisa i-pole) ezicacisweni zakho.

 

Iphutha #3: Ukungawunaki ukubaluleka kokubekezelelana (noma ukukugcizelela kakhulu)

 

Inkinga:Ama-magnets e-Sintered Nd ayancipha ngesikhathi senqubo yokukhiqiza, okwenza imishini yokugaya ngemva kokusinta ibe nzima futhi ibe yingozi (bheka Iphutha #1!). Ukulindela ukubekezelelana “kwensimbi emshinini” (±0.001 in.) akunangqondo futhi kubiza kakhulu. Ngokuphambene nalokho, ukucacisa ukubekezelelana okubanzi kakhulu (±0.1 in.) kungabangela i-magnet engeke isetshenziswe ekuhlanganisweni kwakho.

Isixazululo:

Qonda izindinganiso zemboni:Qonda ukubekezelelana okuvamile “okune-sintered” kwama-magnet e-NdFeB (ngokuvamile ± 0.3% kuya ku-± 0.5% wosayizi, kanti ukubekezelelana okuncane ngokuvamile ± 0.1 mm noma ± 0.005 in.).

Yiba nengqondo:Cacisa ukubekezelelana okuqinile kuphela lapho kubalulekile khona ekusebenzeni, njengezindawo zokuhlangana. Kwezinye izimo, ukubekezelelana okuphansi kungonga izindleko futhi kunciphise ubungozi.

Xoxa ngokugaya:Uma indawo kufanele ibe nembambo kakhulu (isb. ubuso be-chuck), chaza ukuthi ukugaya kuyadingeka. Lokhu kunganezela izindleko ezinkulu kanye nengozi, ngakho-ke yisebenzise kuphela uma kudingeka. Qiniseka ukuthi umenzi uyazi ukuthi yiziphi izindawo ezidinga ukugaya.

 

Iphutha #4: Ukungazinaki izivikelo zemvelo (izimbozo)

Inkinga:Ama-magnets e-neodymium angenalutho agqwala ngokushesha uma evezwa umswakama, umswakama, noma amakhemikhali athile. Ukugqwala kuqala emakhoneni angaphakathi asengozini futhi kunciphisa ngokushesha ukusebenza kukazibuthe kanye nobuqotho besakhiwo. Ukukhetha isembozo esingalungile, noma ukucabanga ukuthi isembozo esijwayelekile sanele ezindaweni ezinzima, kungaholela ekuhlulekeni kwangaphambi kwesikhathi.

Isixazululo:

Ungalokothi ungazinaki izimbozo:I-NdFeB engenalutho ayifaneleki kuma-magnet asebenzayo.

Izembozo kufanele zihambisane nendawo:I-plating ejwayelekile ye-nickel-copper-nickel (Ni-Cu-Ni) ifanele ukusetshenziswa okuningi kwangaphakathi. Ezindaweni ezimanzi, ezimanzi, ezingaphandle, noma ezivezwe kumakhemikhali, chaza ungqimba oluqinile olufana nalokhu:

I-Epoxy/Parylene:Ukumelana okuhle kakhulu nomswakama kanye namakhemikhali, kanye nokushisa ngogesi.

Igolide noma i-zinc:ukuze kuvinjwe ukugqwala okuthile.

I-epoxy ejiyile:ezindaweni ezinzima.

Cacisa ukumbozwa kwekhoneni ngaphakathi:Gcizelela ukuthi isembozo kumele sihlinzeke ngesembozo esifanayo, ikakhulukazi emakhoneni angaphakathi anomfutho ophezulu wohlobo lwe-U. Buza ngesiqinisekiso sabo somsebenzi.

Cabanga ngokuhlolwa kwesifutho sikasawoti:Uma ukumelana nokugqwala kubalulekile, chaza inani lamahora okuhlolwa kokufuthwa kukasawoti (isb., i-ASTM B117) okumele kudlule kumagnethi ambozwe.

 

Iphutha #5: Ukweqa Isigaba Sesibonelo

Inkinga:Kunezingozi zokugxumela oda elikhulu ngokusekelwe kumodeli ye-CAD noma ishidi ledatha kuphela. Izici zangempela ezifana nokusatshalaliswa kokudonsa kwamagnetic, ukulingana kwangempela kwezingxenye, ukusingatha ubuthakathaka, noma ukusebenzisana okungalindelekile kungabonakala kuphela ngesampula ebonakalayo.

 

Isixazululo:

Oda ama-prototypes: bhajethi bese ugcizelela ukuthi uthole inqwaba yama-prototypes kuqala.

Hlola ngokucophelela: Faka ama-prototype ezimweni zangempela:

Qinisekisa ukuthi i-assembling iyasebenza futhi iyasebenza.

Izilinganiso zokudonsa zangempela (ingabe ziyahlangabezana nezidingo zakho?).

Ukuhlolwa kokuphatha (ingabe kuzosinda ukufakwa?).

Ukuhlolwa kokuchayeka endaweni ezungezile (uma kusebenza).

Phindaphinda njengoba kudingeka: Sebenzisa impendulo yesibonelo ukuze uthuthukise ubukhulu, ukubekezelelana, ukumbozwa, noma amamaki ngaphambi kokuzibophezela ekukhiqizeni okubizayo.
