Sintered NdFeB magineti echigarire, sechimwe chezvinhu zvakakosha kusimudzira tekinoroji yemazuva ano uye kufambira mberi munharaunda, anoshandiswa zvakanyanya mundima dzinotevera: komputa hard disk, nuclear magnetic resonance imaging, mota dzemagetsi, kugadzirwa kwesimba remhepo, maindasitiri anogara magineti mota, zvemagetsi zvevatengi. (CD, DVD, nharembozha, odhiyo, makopi, scanner, vhidhiyo kamera, makamera, mafiriji, TV seti, air conditioners, nezvimwewo) uye magineti. michina, magineti levitation tekinoroji, magineti kutapurirana uye mamwe maindasitiri.
Mumakore makumi matatu apfuura, indasitiri yepasi rose yemagineti yezvinhu yanga ichikura kubvira 1985, apo indasitiri yakatanga kugadzirwa muJapan, China, Europe neUnited States, uye iyo magineti zvinhu zvave kuisa zvinyorwa zvitsva uye kuwedzera huwandu hwe zvinhu zvakasiyana-siyana uye mamakisi. Pamwe pamwe nekuwedzera kwemusika, vagadziri vari kuwedzerawo, uye vatengi vazhinji vanobatwa zvisingadzivisiki mukuvhiringidzika uku, maitiro ekutonga kunaka kwechigadzirwa? Iyo yakanyanya kuwanda nzira yekutonga: yekutanga, magineti kuita; chechipiri, saizi yemagineti; chechitatu, magnet coating.
Kutanga, iyo vimbiso yekushanda kwemagineti inobva pakutonga kwemaitiro ekugadzirwa kwezvinhu
1, Zvinoenderana nezvinodiwa zvebhizinesi rekugadzira yakakwira-giredhi kana yepakati-giredhi kana yakaderera-giredhi sintered NdFeB, iyo mbishi kuumbwa zvinoenderana nenyika chiyero chekutenga zvigadzirwa.
2, Iyo yepamusoro yekugadzira maitiro inotarisa zvakananga maitiro ekuita kwemagineti. Parizvino, matekinoroji epamusoro soro tekinoroji Scaled Ingot Casting (SC), Hydrogen Crushing (HD) tekinoroji uye Airflow Mill (JM) tekinoroji.
Madiki madiki ekunyungudutsa mavhuni ekunyungudutsa (10kg, 25kg, 50kg) akatsiviwa nehukuru hukuru (100kg, 200kg, 600kg, 800kg) vacuum induction furnaces, SC (StripCasting) tekinoroji yakatsiva zvishoma nezvishoma ingots hombe (ingots nehupamhi hukuru kupfuura makumi maviri. 40mm munzira yekutonhora), HD (Hydrogen Kupwanya) tekinoroji uye gasi kuyerera chigayo (JM) pachinzvimbo chejaw crusher, disc chigayo, bhora chigayo (wet poda kugadzira), kuve nechokwadi chekufanana kwehupfu, uye inokodzera kumvura chikamu sintering uye kunatswa zviyo.
3, Pamusoro pemagineti yekutarisa, China ndiyo chete nyika pasi rose inotora nhanho mbiri kuumbwa, ine diki yekumanikidza yakatwasuka kuumbwa kwekutarisa uye quasi-isostatic molding kumagumo, inova chimwe chezvinhu zvinonyanya kukosha zveSintered yeChina. NdFeB indasitiri.
Chechipiri, vimbiso yehukuru hwemagineti inoenderana nesimba rekugadzirisa fekitori
Iko kushandiswa chaiko kweNdFeB magineti echigarire ane zvimiro zvakasiyana, senge denderedzwa, cylindrical, cylindrical (ine mukati mukati megomba); sikweya, sikweya, mativi mana; tile, fan, trapezoid, polygon uye akasiyana maumbirwo asina kujairika.
Chimiro chega chega chemagineti asingagumi ane saizi dzakasiyana, uye maitiro ekugadzira akaoma kuumbwa mune imwe kuenda. Iyo yakajairika kugadzirwa maitiro ndeiyi: Mr. yakabuda yakakura (yakakura saizi) blanks, mushure mekupisa uye kupisa kurapwa, zvino kuburikidza nemuchina kugadzirisa (kusanganisira kucheka, kubaya) uye kugaya, pamusoro plating (kupfeka) kugadzirisa, uyezve kuita magineti, mhando yepamusoro uye. dimensional kunyatso kuyedza, uyezve magnetization, kurongedza uye fekitori.
1, magadzirirwo emagetsi akakamurwa kuita zvikamu zvitatu: (1) kucheka kugadzira: kucheka cylindrical, magineti akaenzana-skweya kuita denderedzwa, sikweya-yakaumbwa, (2) kugadzirwa kwechimiro: kugadzirisa kutenderera, sikweya magineti kuita fan-shaped, tile-shaped kana ine magineti kana mamwe maumbirwo akaomarara emagineti, (3) kubaya kugadzirisa: kugadzirisa denderedzwa, sikweya-yakaita magineti kuita cylindrical kana square-shaped magineti. Nzira dzekugadzirisa ndeidzi: kukuya uye slicing processing, EDM yekucheka kushandiswa uye laser processing.
2, Iyo yepamusoro yeSintered NdFeB yekusingaperi magineti zvikamu zvinowanzoda kutsvedzerera uye kumwe kurongeka, uye nepamusoro pemagineti inounzwa isina chinhu inoda pamusoro pekukuya kugadzirisa. Iyo yakajairika nzira dzekukuya dzeskweya NdFeB zvechigarire magineti alloy ndeyekukuya ndege, kaviri kupera kukuya, kugaya mukati, kugaya kwekunze, etc. Cylindrical inowanzoshandiswa coreless grinding, double end grinding, etc. For tile, fan uye VCM magineti, multi-station grinding. inoshandiswa.
Iyo magineti inokwanisa haingodi chete kusangana neyakajairwa chiyero, asiwo iyo dimensional kushivirira kutonga inobata zvakananga mashandisiro ayo. Iyo dimensional garandi zvakananga zvinoenderana nesimba rekugadzirisa fekitori. Midziyo yekugadziridza inogara ichigadziridzwa nehupfumi uye kudiwa kwemusika, uye maitiro emidziyo inoshanda zvakanyanya uye maindasitiri otomatiki haangoite kuzadzisa kudiwa kuri kukura kwevatengi kwekurongeka kwechigadzirwa, asi zvakare kuchengetedza manpower uye mutengo, zvichiita kuti zviwedzere kukwikwidza musika.
Zvekare, iyo mhando yemagineti plating inotaridza zvakananga hupenyu hwekushandisa kwechigadzirwa
Nezvekuedza, 1cm3 sintered NdFeB magineti ichasvibiswa neoxidation kana ikasiiwa mumhepo pa150 ℃ kwemazuva makumi mashanu nerimwe. Mune isina kusimba asidhi mhinduro, inowanzove yakasvibiswa. Kuti uite kuti NdFeB magineti agare akasimba, zvinodikanwa kuve nehupenyu hwesevhisi hwemakore makumi maviri-30.
Inofanirwa kurapwa neanti-corrosion kurapwa kudzivirira kukora kwemagneti nezvinosvibisa media. Parizvino, iyo sintered NdFeB magineti anowanzo kuputirwa nesimbi plating, electroplating + makemikari plating, electrophoretic coating uye phosphate kurapwa kudzivirira magineti kubva mukuora svikiro.
1, anowanzo galvanized, nickel + mhangura + nickel plating, nickel + mhangura + makemikari nickel plating matatu maitiro, mamwe simbi plating zvinodiwa, anowanzo shandiswa mushure mekugadzira nickel uyezve imwe simbi plating.
2, mune mamwe mamiriro akakosha achashandisawo phosphating: (1) muNdFeB magineti zvigadzirwa nekuda kwekuchinja, kuchengetedza nguva yakarebesa uye haina kujeka kana yakatevera pamusoro pekurapa nzira, kushandiswa kwephosphating nyore uye nyore; (2) kana magineti ichida epoxy glue bonding, pendi, nezvimwewo, glue, pendi uye imwe epoxy organic adhesion inoda kuita kwakanaka kupinza kweiyo substrate. Phosphating process inogona kuvandudza pamusoro pesimba remagineti kupinda mukati.
3, electrophoretic coating yave imwe yeinonyanya kushandiswa anti-corrosion pamusoro pekurapa tekinoroji. Nekuti haina kungove nekubatana kwakanaka neporous magnet pamusoro, asiwo ine corrosion resistance kune salt spray, acid, alkali, etc., yakanakisa anti-corrosion. Zvisinei, kuramba kwayo kunyoro uye kupisa hakuna kunaka kana ichienzaniswa nekupfapfaidza coating.
Vatengi vanogona kusarudza coating zvinoenderana nechigadzirwa chavo chekushanda zvinodiwa. Nekuwedzera kwemunda wekushandisa mota, vatengi vane zvakakwirira zvinodikanwa zvekupokana kweNdFeB. Iyo HAST bvunzo (inodaidzwawo kuti PCT bvunzo) ndeyekuyedza kuramba kwecorrosion yeSintered NdFeB magineti echigarire pasi pehunyoro uye tembiricha yakakwira.
Uye mutengi angatonga sei kuti plating inosangana nezvinodiwa kana kwete? Chinangwa chemunyu chekupfapfaidza bvunzo ndechekuita kukurumidza anti-corrosion bvunzo pane sintered NdFeB magineti ayo kumeso kwakabatwa neanti-corrosion coating. Pakupera kwebvunzo, sampu inotorwa kubva mukamuri yekuyedza, yakaomeswa, uye inotariswa nemaziso kana girazi rinokudza kuti uone kana paine makwapa pamusoro pesample, saizi yenzvimbo yenzvimbo bhokisi shanduko yeruvara.
