Xa abantu abaninzi besiva Ukukhutshwa kwe-OEM, bacinga ngentengiselwano elula: uthumela umzobo, bathumela umva iinxalenye. Leyo yeyona mbono iphosakeleyo. Inyaniso kukuba, luthethathethwano—kungekhona ngexabiso, kodwa kwifiziksi, ukuziphatha kwezinto eziphathekayo, kunye nenyaniso emdaka yokuguqula imodeli ye-3D ibe sisiqwenga esiqinileyo, esisebenzayo. Ndibone iiprojekthi ezininzi zivaliwe kuba umthengi ugxile kuphela kwijometri yokugqibela, ephatha inkqubo yokuphosa njengebhokisi emnyama. Inyani yile, ukuba awuxoxi ngoyilo lwe-gating, ukucutha kwe-thermal, okanye umahluko phakathi kweqokobhe le-ceramic kunye nokubumba kwesanti ngaphambili, uyaqikelela.
Isiseko: Yonke imalunga nokuKhethwa kweNkqubo
Awukhethi nje inkqubo yokuphosa. Ikhetha wena, ngokusekelwe kumsebenzi wenxalenye yakho. Oku sakufunda kabuhlungu kwasekuqaleni. Umxhasi unyanzelise ukuba asebenzise ukubumba iqokobhe into entsonkothileyo, enodonga olucekeceke olungenasicingo ngenxa yokuba beyibonile isebenzela indawo elula. Isiphumo? Ukuvalwa okubandayo okuzingisileyo kunye nesantya esingamkelekanga sokulahlwa. Ijometri ayikwazanga ukumelana nokupholisa ngokukhawuleza kwenkqubo yokubumba iqokobhe. Kuye kwafuneka sijike kwi-investment casting, apho indlela yeqokobhe elilodwa leceramic kunye nokupholisa okulawulwayo kusinike imfezeko esiyifunayo. Nantso umnxeba wokuqala wokugweba: ukuthelekisa inkqubo nomphefumlo wenxalenye, hayi nje isithunzi sayo.
Kulapho iqabane elinenkqubo ebanzi yepotifoliyo lixabiseke kakhulu. Jonga inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY). Ngaphezulu kwamashumi amathathu eminyaka kumdlalo, ababotshelelwanga kwindlela enye. Uluhlu lwabo-ukusuka kwi-shell mold ukuya kwi-investment casting-ithetha ukuba banokucebisa ngokusekelwe kwimfuno yangempela. Ndikhumbula bephonononga indlela yabo yothotho lwemizimba yevalvu. Ukufumana i-iron ephezulu, engantsonkothanga kangako, batyhalela ukubumba iqokobhe-ukugqiba umgangatho omkhulu, ukunyamezelana okufanelekileyo, ukonga imali kwisikali. Kwii-impellers ezibaluleke kakhulu, ezinganyangekiyo ku-corrosion kwii-alloys ezikhethekileyo, yayilutyalo-mali oluphosa yonke indlela. Obo bhetyebhetye busebenzisekayo, obungenasihlahla buyinto eyahlula iqabane lokwenyani lemveliso kwivenkile yemisebenzi.
Ukhetho lwezinto eziphathekayo luluhlu olulandelayo. Intsimbi engatyiwayo ayiyonto; lusapho. I-304 engacocekanga iziphatha ngokwahlukileyo kumngundo kune-316, kwaye ungandiqalisi kwiimpawu zokugalela zento efana ne-nickel-based alloy. I-alloy ichaza iiparameters zenkqubo njengoko imilo yenza. Awukwazi nje ukuwatshintsha kumzobo kwaye ulindele umphumo ofanayo.
UMtyholi kwiiNkcukacha: I-DFM kunye noMzobo ongaguqukiyo
UYilo lokuVeliswa (DFM) sesona sigaba sibaluleke kakhulu, kodwa esihlala singxamile, isigaba. Ndiye ndahlala iintlanganiso ezingenakubalwa apho injineli ikhusela ikona yangaphakathi ebukhali okanye udonga olungalungelelananga ubukhulu kuba yiloo nto ukulinganisa okulungiselelweyo. Kodwa ukulinganisa akuthululi isinyithi esityhidiweyo. Loo kona ibukhali iba yindawo yoxinzelelo ngexesha lokuqina, umqalisi wokuqhekeka oqinisekisiweyo. Ulungile Ukukhutshwa kwe-OEM iqabane liya kutyhala ngasemva. Baza kucebisa iradii, icebise ii-engile zokuyila ezibonakala zigqithise kwiscreen kodwa ziyimfuneko ekuhlubeni ipateni, kunye nomlinganiselo wobunzima bodonga lombuzo.
Umzekelo osebenzayo: sasinobiyela kumatshini wezolimo. Uyilo lwantlandlolo lwalunolwakhiwo oluhle lweembambo, olunobunzima obulungelelanisiweyo. Ijongeka igqibelele. Iisampulu zokuqala ezivela kwi-Foundry, ukusuka kwindawo ehloniphekileyo ngelo xesha, zibonise ukugqwetheka kunye neenyembezi ezishushu kunye neembambo. Ingxaki? Iimbambo zenza iindawo ezishushu ezizimeleyo aphole ekugqibeleni, ukutsala kunye nokukrazula izinto ezijikelezileyo. Isisombululo yayingekokutshintsha i-alloy okanye inkqubo, kodwa ukuguqula kancinane ubambo lwejometri-i-tapering, ukongeza i-reliefs encinci-ukukhuthaza ukupholisa okufanayo. Yongeza ubunzima obungabalulekanga kodwa yagcina inxalenye. Olo luhlobo lwe-gritty, i-DFM ebonakalayo eyenzekayo phambi kokuba ipateni enye yenziwe.
Eli linqanaba apho ukungafihli kweqela lobunjineli bomthengisi wakho kuyigolide. Ufuna ukubona uhlalutyo lokuhamba kwenkqubo, i-gating yabo ecetyisiweyo kunye noyilo lokunyuka. Ukuba ababoneleli oko, okanye ukuba bamkela umzobo wakho ngaphandle kokuphawula, lumka kakhulu. Basenokuba baceba ukukuhlawulisa ngesixhobo esingenakuthintelwa kwakhona kamva.
Umatshini: Iqabane elingenakwahlulwa
Akukho kuphoswa kukumila kwenetha ngokwenene. Nabani na othembisa ukuba ngenxa yecandelo elichanekileyo lijongene. Kuya kuhlala kukho ujongano olubalulekileyo-indawo yokutywina, imingxuma yeebholiti, izihlalo ezithweleyo-ezifuna ukwenziwa ngoomatshini. Yiyo loo nto udibaniso lokuphosa kunye nomatshini phantsi kophahla olunye, okanye ubuncinci phantsi kwenkqubo yolawulo lweprojekthi elungelelanisiweyo, akunakuxoxiswana ngokunzulu. Ukukhutshwa kwe-OEM umsebenzi. Ulwakhiwo lwedatha yomatshini kufuneka lusekwe ngexesha lesigaba sokuyila.
Ndiyibonile isiphithiphithi sokwenziwa komdlalo kwindawo enye kunye nomatshini kwelinye. Usomashishini kamatshini uya kuchitha isiqingatha sexesha lakhe ezama ukufumana i-datum engaguqukiyo kwindawo ephoswe phantsi, ehlala kufuneka athathe ubunzulu obugqithisileyo kuqala ukuze acoce umphezulu, olahla yonke imilinganiselo elandelayo kunye nenkunkuma yemathiriyeli. Xa ukuphosa kunye nomatshini kulungelelaniswa, njengakwi-QSY apho banikezela ngomatshini odibeneyo we-CNC, ipateni inokuthi iyilwe kunye ne-machining lugs okanye iimpawu ezithile ze-datum ezifakwe kuyo. Ijika intloko ebuhlungu enokubakho ibe yimpompo elungelelanisiweyo.
Ukukhethwa kwesicwangciso somatshini nako kuxhomekeke ekubunjweni. Ukubunjwa kokungunda kweqokobhe kunokuba nesitokhwe esincinci sokususa kodwa isikali esinzima. Utyalo-mali lunokuba nesibonelelo esingaguqukiyo sesitokhwe kodwa senziwe ngegummy, eyomeleleyo kumatshini we-superalloy. Iqela loomatshini kufuneka lazi ukuba yintoni eza ngendlela yabo ukusuka kumgangatho wesiseko.
Izinto ezifihlakeleyo zeMathiriyeli kunye ne-Special Alloys Gamble
Ukusebenza ngentsimbi eqhelekileyo okanye i-carbon steel yinto enye. Ukungena kwi-cobalt-based okanye i-nickel-based alloys yiligi eyahlukileyo. Akunjalo malunga namanqaku aphezulu okunyibilika. Ezi ngxubevange zinolwelo olubi, zityekele kwi-micro-porosity, kwaye zinokuphinda zisebenze ngokuphambeneyo neoksijini. Umngundo wakho wesanti ye-silica oqhelekileyo awuyi kuwusika; ufuna iirefractories ezikhethekileyo. Inkqubo yokungena kufuneka yenzelwe ukunciphisa ukuphazamiseka kuzo zonke iindleko-i-turbulence ikhokelela ekufakweni kwe-oxide, okuba ngamanqaku angaphumeleli phantsi kokushisa okuphezulu okanye uxinzelelo.
Sakhe sazama ukusebenzisa imilomo yokutshisa kwi-cobalt alloy ene-foundry egqwesileyo ngentsimbi. Bawujonga njengomnye umsebenzi. Ukunyibilika kujongeka kakuhle, kodwa ukuphoswa kwe-casts kusilele kuvavanyo loxinzelelo ngokumangalisayo. I-post-mortem ibonakalise inethiwekhi ye-micro-shrinkage kunye neefilimu ze-oxide. I-Foundry ayizange isebenzise izinyusi ze-exothermic ngokwaneleyo ukondla i-shrinkage enkulu yokuqina, kwaye ukuziqhelisa kwabo ukugalela kwazisa isiphithiphithi esikhulu kakhulu. Yayiyilahleko epheleleyo. Kungenxa yoko le nto ufuna iqabane onobugcisa bezinto eziphathekayo bucacileyo. Ukubona ukuba i-QSY idwelisa ii-alloys ezikhethekileyo ezifana nezi ngqo kwindawo yazo (https://www.tsingtaocnc.com) luphawu lokuba kusenokwenzeka ukuba bakhe ulwakhiwo olukhethekileyo kunye nolwazi-ukusuka kulawulo lwesinyithi ukuya kubunjineli bokubumba-ukuyiphatha.
Umkhondo wokuqinisekiswa kwezi mathiriyeli ubalulekile. Awuthenganga nje imilo; uthenga umnombo wezinto eziphathekayo. Ngaba banokubonelela ngeengxelo ezinyibilikayo? Iitshathi zonyango lobushushu? Iikhuphoni zovavanyo lomatshini kubushushu obufanayo? Ukuba akunjalo, awukwazi ukusebenzisa inxalenye kuso nasiphi na isicelo esibalulekileyo.
Umdlalo omde: Ukungqinelana kunye noHlahlelo lokuSilela
Uvavanyo lokwenyani lwe Ukukhutshwa kwe-OEM umthengisi ayilonqaku lokuqala. Ngumhla we-10,000. Ngaba banokubamba ibhendi yokunyamezelana? Ngaba i-microstructure ihlala ihambelana ukusuka kwibhetshi ukuya kwibhetshi? Ngaba iipropathi zomatshini zokuqhuba kwemveliso yesihlanu ziyahambelana neyokuqala? Apha kulapho iinkqubo zolawulo lwenkqubo kunye nenkcubeko yamaxwebhu ibaluleke ngaphezu kwesithando somlilo esitsha.
Ndibaxabisile ababoneleli abanokuthetha malunga nolawulo lwenkqubo yobalo (i-SPC) kwimilinganiselo ebalulekileyo, isanti yabo okanye iindlela zokulondoloza uludaka, kunye nokugawulwa kwamaqondo obushushu eziko. Yinto ekruqulayo, kodwa yinto ethintela imeko yomgca-phantsi kwiminyaka emibini ibe yinkqubo. Iqabane elilungileyo liya kuba neprotocol ehambelanayo yohlalutyo lokusilela. Xa inxalenye ingaphumeleli ekuvavanyeni intsimi, kufuneka ikwazi ukusebenzisana kuhlalutyo lwe-forensic-ukuhlola iindawo zokuphuka phantsi kwe-microscope, ukujonga i-dendrite arm spacing, ukukhangela ukuhlukana. Ayikokubeka ityala; imalunga nokusombulula iphazili yomzimba.
Oku kuhambelana kwexesha elide yinto eyenza umthengisi abe liqabane lobuchule. Ngumahluko phakathi kokuhlala uhlola yonke into ethunyelwayo kunye nokukwazi ukuya kwimodeli yenqanawa ukuya kwisitokhwe. Oko kuthenjwa kwakhelwe phezu kwesiseko solwazi oluselubala, olungenamfezeko, olusebenzisekayo lokwenziwa kwezinto, kungekhona kwiincwadana ezinemifanekiso. Kungokwazi ukuba abantu kwelinye icala le-imeyile banegrisi phantsi kweminwe yabo kunye namava emehlweni abo ukubona ingxaki ngaphambi kokuba ibe yingxaki. Yiloo nto oyifuna ngokwenene kwi-OEM casting.
