5 Amaphutha Okufanele Uwagweme Uma Wenza Ngokwezifiso Uzibuthe Obunjwe Nge-Neodymium

Ozibuthe be-neodymium abamise u-U bayindlu yamandla. Idizayini yazo eyingqayizivele igxilisa inkambu kazibuthe eqine ngokwedlulele endaweni ehlangene, okuyenza ilungele izinhlelo zokusebenza ezinzima ezifana nama-chuck kazibuthe, izinzwa ezikhethekile, amamotho anetorque ephezulu, nezakhiwo ezimangelengele. Nokho, ukusebenza kwazo okunamandla kanye nokuma kwazo okuyinkimbinkimbi nakho kuzenza kube nzima ukuzenza ngendlela oyifisayo. Iphutha elilodwa lingaholela ekumoshweni kwemali, ukubambezeleka kwephrojekthi, noma ngisho nokwehluleka okuyingozi.

 

Gwema lawa maphutha ama-5 abalulekile ukuze uqinisekise ukuthi omazibuthe bakho be-neodymium obuka-U basebenza kahle nangokuphephile:

 

Iphutha #1: Ukuziba I-Material Brittleness kanye Namaphuzu Okucindezeleka

 

Inkinga:Ozibuthe be-Neodymium (ikakhulukazi amamaki aqine kakhulu njenge-N52) ngokwemvelo bashwabene, njengobumba obucolekileyo. Amakhona acijile e-U-shape adala amaphuzu okugxilisa ukucindezeleka emvelo. Ukwehluleka ukulandisa ngalokhu konakala lapho kubalula ubukhulu, ukubekezelelana, noma izimfuneko zokuphatha kungaholela ekuqhekekeni noma ekuqhekekeni okuyinhlekelele phakathi nokukhiqiza, ukudonsa uzibuthe, ukuthunyelwa, ngisho nokufakwa.

Isixazululo:

Cacisa Irediyasi Enkulu:Idinga irediyasi enkulu kunazo zonke ekhona ngaphakathi kwekhona (R) idizayini yakho engakwazi ukuyiphatha. Ukugoba okuqinile okungu-90-degree kungu-cha-cha.

Khetha ibanga elilungile:Kwesinye isikhathi ibanga eliphansi kancane (isb, i-N42 esikhundleni sika-N52) linganikeza ukuqina okungcono kokuphuka ngaphandle kokudela amandla adingekayo kakhulu.

Xhumana nezidingo zokuphatha:Qinisekisa ukuthi umenzi wakho uyaqonda ukuthi omagnet bazophathwa futhi bafakwe kanjani. Bangase batuse ukupakishwa okuvikelekile noma izinto zokubamba.

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

 

Iphutha #2: Ukuklama ngaphandle kokucabangela isiqondiso samagnetization

 

Inkinga:Ozibuthe be-NdFeB bathola amandla abo kumagnetizing baqonde endaweni ethile ngemuva kokucwilisa. Ozibuthe abamise okwe-U, izigxobo cishe zihlala ekugcineni kwemilenze. Uma ucacisa umumo oyinkimbinkimbi noma usayizi ovimbela i-magnetizing fixture ukuthi ixhumane kahle nobuso besigxobo, uzibuthe ngeke afinyelele amandla awo aphezulu noma angase abangele amaphutha kazibuthe.

Isixazululo:

Xhumana kusenesikhathi:Xoxa ngomklamo wakho nomkhiqizi kazibuthe ngaphambi kokuwuphothula. Futhi buza mayelana nezidingo ze-magnetizing fixture kanye nemikhawulo.

Beka kuqala ukufinyeleleka kobuso be-pole:Qinisekisa ukuthi idizayini ivumela ukufinyelela okucacile, okungavimbeliyo kwekhoyili yamagnethi endaweni yonke yesiphetho ngasinye.

Qonda umumo:Yisho ngokucacile umumo ozibuthe owufunayo (i-axially ngokusebenzisa isigxobo) ezincazelweni zakho.

 

Iphutha #3: Ukubukela phansi ukubaluleka kokubekezelelana (noma ukukuqinisa kakhulu)

 

Inkinga:Ozibuthe be-Sintered Nd bayashwabana ngesikhathi senqubo yokukhiqiza, okwenza ukuba imishini ye-post-sintering ibe nzima futhi ibe yingozi (bona Iphutha #1!). Ukulindela ukubekezelelwa "kwensimbi yomshini" (±0.001 in.) akunangqondo futhi kubiza kakhulu. Ngokuphambene, ukucacisa ukubekezelelana okubanzi kakhulu (±0.1 in.) kungase kubangele uzibuthe ongakwazi ukusetshenziswa ekuhlanganiseni kwakho.

Isixazululo:

Qonda amazinga embonini:Qonda ukubekezelelana okujwayelekile “oku-sintered” kozibuthe be-NdFeB (imvamisa ±0.3% kuya ku-±0.5% kasayizi, nokubekezelela okuncane ngokuvamile okungu-±0.1 mm noma ±0.005 in.).

Yiba ne-pragmatic:Cacisa ukubekezelelana okuqinile kuphela lapho kubaluleke khona ukusebenza, njengendawo yokukhwelana. Kwezinye izimo, ukubekezelelana okuphansi kungasindisa izindleko futhi kunciphise ingozi.

Xoxa ngokugaya:Uma indawo kufanele inembe kakhulu (isb, ubuso be-chuck), cacisa ukuthi ukugaya kuyadingeka. Lokhu kungengeza izindleko ezinkulu nengcuphe, ngakho-ke yisebenzise kuphela uma kunesidingo. Qiniseka ukuthi umenzi uyazi ukuthi yiziphi izindawo ezidinga ukugaywa.

 

Iphutha #4: Ukuziba ukuvikelwa kwemvelo (ama-coatings)

Inkinga:Ozibuthe be-neodymium abangenalutho bagqwala ngokushesha lapho bechayeke kumswakama, umswakama, noma amakhemikhali athile. Ukugqwala kuqala emakhoneni angaphakathi asengozini futhi kwehlisa ngokushesha ukusebenza kazibuthe kanye nobuqotho besakhiwo. Ukukhetha i-coating engalungile, noma ucabange ukuthi ukunamathela okujwayelekile kwanele ezindaweni ezinokhahlo, kungaholela ekuhlulekeni ngaphambi kwesikhathi.

Isixazululo:

Ungalokothi uzibe ama-coatings:I-Bare NdFeB ayifanele izibuthe ezisebenzayo.

I-coatings kufanele ihambisane nemvelo:Ukufakwa okujwayelekile kwe-nickel-copper-nickel (Ni-Cu-Ni) kulungele ukusetshenziswa okuningi kwasendlini. Ezindaweni ezimanzi, ezimanzi, ezingaphandle, noma ezichayeke kumakhemikhali, cacisa ukunamathela okuqinile okufana nalokhu:

I-Epoxy/Parylene:Umswakama omuhle kakhulu nokumelana namakhemikhali, nokufakwa kukagesi.

Igolide noma i-zinc:ngokumelana nokugqwala okuthile.

I-epoxy ewugqinsi:ezindaweni ezinokhahlo.

Cacisa ukumbozwa kwekhona langaphakathi:Gcizelela ukuthi ukugqoka kufanele kunikeze ukumbozwa okufanayo, ikakhulukazi ekucindezelekeni okuphezulu ngaphakathi kwamakhona we-U-shape. Buza ngesiqinisekiso sabo sokusebenza.

Cabangela ukuhlolwa kwesifutho sikasawoti:Uma ukumelana nokugqwala kubalulekile, cacisa inani lamahora okuhlolwa kwesifutho sikasawoti (isb, i-ASTM B117) okumele kudlule uzibuthe oboshwe.

 

Iphutha #5: Ukweqa Isigaba Se-Prototype

Inkinga:Kukhona ubungozi ekugxumeni ku-oda elikhulu ngokusekelwe kumodeli ye-CAD noma idatha yedatha iyodwa. Izinto zomhlaba wangempela ezifana nokusabalalisa kokudonsa kazibuthe, ukulingana kwangempela kwezingxenye, ukubamba ubuthakathaka, noma ukusebenzisana okungalindelekile kungase kubonakale kuphela ngesampula ebonakalayo.

 

Isixazululo:

Oda ama-prototypes: isabelomali futhi ugcizelele eqoqweni elincane lama-prototypes kuqala.

Hlola ngokuqinile: Isihloko se-prototypes ezimweni zomhlaba wangempela:

Qinisekisa ukufaneleka nokusebenza ekuhlanganiseni.

Izilinganiso zokudonsa zomhlaba wangempela (ingabe ziyahlangabezana nezidingo zakho?).

Ukuphatha izivivinyo (ingabe kuzosinda ekufakweni?).

Ukuhlolwa kokuchayeka kwemvelo (uma kusebenza).

Phinda futhi njengoba kudingeka: Sebenzisa impendulo ye-prototype ukuze uthuthukise ubukhulu, ukubekezelela, ukunamathela, noma amabanga ngaphambi kokuzibophezela ekukhiqizeni okumba eqolo.
