Xa abantu abaninzi besiva 'iinkampani zokugalela isanti', baba nomfanekiso ngqondweni womgangatho omdaka nonothuli, ogalela nje isinyithi kwizibumba zesanti. Lo ngumfanekiso oqhelekileyo, kodwa malunga ne-20% yebali namhlanje. Owona mceli mngeni, kwaye apho iiprojekthi ezininzi zichithwa khona, ayikokuziphosa ngokwako-yinto yonke eyenzekayo phambi kokuba isinyithi sibethe esantini kwaye emva kokuba ipholile. Yingxelo yoyilo, ukwenza iipateni, ukuphoswa komatshini, kunye nesayensi yezinto ezisemva kwayo. Ukuba uthenga nje ukuphosa, mhlawumbi ushiya ixabiso-kunye nokuthembeka-kwitafile.
Ingcamango ephosakeleyo engundoqo: Yinto nje yoRhwebo
Uninzi lwamaqela okuthenga aphatha ukugalelwa kwesanti njengento elula yokuthenga. Thumela umzobo, fumana isicatshulwa, khetha eyona xabiso liphantsi, linda iindawo. Loo ndlela yindlela yokunceda iintloko ezibuhlungu. Inkqubo yokugalela isanti iguquguquka ngendlela emangalisayo, kodwa oko kuguquguquka kuthetha ukuba isiphumo sixhomekeke kakhulu kubuchule be-Foundry. Ubungakanani besanti yesanti, i-binder system (isanti eluhlaza kunye ne-resin-bonded, umzekelo), uyilo lokungena-ezi ayizonkcukacha ezincinci. Bayalela iipropathi zoomatshini, ukugqitywa komphezulu, kunye nokubakho kweziphene ezifihliweyo njenge-shrinkage porosity.
Ndibone iindawo eziyilwe kakuhle zisilela ekuvavanyeni ngenxa yokuba isiseko esikhethiweyo esekwe kwixabiso sisebenzise inkqubo yesanti engafanelekanga kakhulu yejometri, ekhokelela ekupholiseni okungahambelaniyo. Umzobo wabiza ibakala elithile le-iron ductile, kunye nengxelo yekhemistri ehambelanayo, kodwa i-microstructure yayingalunganga ngenxa yokuba izinga lokupholisa ekubunjeni lalingalunganga. I-Foundry yenza kanye le nto yayikushicilelo, kodwa ushicilelo aluzange-kwaye alukwazanga ukucacisa iiparameters zenkqubo ye-Foundry. Nantso isithuba.
Apha kulapho abadlali abasekwe ixesha elide bazahlula khona. Ayikokuba neziko ezinkulu; imalunga nokuba ne-metallurgical kunye nobunjineli benkqubo ngaphakathi endlwini ukukhokela uyilo. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ngokomzekelo, kwiminyaka yabo engama-30 besenza izinto ezenziwe ngomatshini nokwenza, kusenokwenzeka ukuba olo lwazi lwendele nzulu. Ungazifumana kwindawo yazo, tsngtaocnc.com. Ujoliso lwabo alukho nje ekwenzeni umngundo; idweliswe kanye apho: ziyadibanisa iqokobhe ngundo ukuphosa kwaye utyalo mali ubungcali nge CNC Machining. Olu luphawu lokuba bacinga ngalo lonke ikhonkco lokuvelisa, hayi nje inyathelo lokuqala.
Ikhonkco eliBalulekileyo: Ukusuka kwiCasting ukuya kuMachining
Lo ngoyena mqhubi weendleko ngokungahoywanga. Ukujulwa kwesanti kuphuma kunye nee-engile zokuyila, imigca yokwahlula, kunye nemathiriyeli engaphezulu (isango kunye nenkqubo yokunyuka). Ukuyicupha ukuya kwimilinganiselo yokugqibela inikwe. Kodwa ukuba umthengisi ophosayo kunye nevenkile yomatshini zizigqeba ezahlukileyo, ufumana umdlalo onetyala. Umchwephesha ufumana indawo enzima okanye indawo engenanto engaphantsi komhlaba, kwaye ngumlo wokuba ngubani onetyala-isiseko sokuphosa okubi okanye i-machinist yokuthatha inxeba elinzima kakhulu.
Ababoneleli abadibeneyo, abo bayinyaniso iinkampani zokugalela isanti ekwaphatha umatshini, yisuse loo nto. Bangabanikazi bayo yonke inkqubo ukusuka kwintsimbi etyhidiweyo ukuya kwinxalenye egqityiweyo. Kwi-QSY, bachaza ngokucacileyo ukusebenza ngentsimbi, intsimbi, i-stainless, kunye ne-alloys ezikhethekileyo ezifana ne-cobalt kunye ne-nickel-based based. Ukwenza ezi zinto, ngakumbi ii-superalloys, yinto ekhethekileyo ngokwayo. Ukuba ne-casting kunye ne-machining phantsi kophahla olunye kuthetha ukuba banokuluphucula uyilo lokuphosa ukuze bakwazi ukulungelelanisa-mhlawumbi ukongeza isitokhwe esincinci kwindawo ekhohlisayo besazi ukuba isebe labo le-CNC liya kuyiphatha. Sele beyibambile into ephazanyiswe kunyango lobushushu phambi kokuba kwenziwe ukusika kokuqala. Ayinamthungo.
Ndikhumbula iprojekthi yomzimba wevalve kwi-stainless 316. Iisampulu zokuqala zomniki-mveliso we-Foundry-kuphela asebenza kakuhle, enencoko yesixhobo kunye nokuguga okukhawulezayo. Sizise ingxaki kumnikezeli odibeneyo. Isisombululo sabo sasinobuqili: bahlengahlengisa amaphiko okupholisa kwisibuko kancinci ukuguqula ulandelelwano lokuqiniswa, okukhokelela kubunzima obufanayo kwiindawo eziza kumatshini. Umzobo awuzange utshintshe, kodwa inxalenye yokuphoswa yayinamandla ngakumbi. Olo hlobo lolungiso luvela kuphela ekulawuleni zombini iinkqubo.
UKhetho Lwezinto Zokusebenza AyiyoMenyu Yokulahla Nje
Abathengi bahlala beza besithi, Ndiyifuna ngentsimbi engatyiwa. Kulungile, kodwa yeyiphi? 304 ukwenzela umhlwa jikelele? 316 yekloridi? Okanye i-CF8M cast elinganayo? Kwaye yeyomthwalo wesakhiwo okanye isiqulatho solwelo nje? Ukhetho luchaphazela ngokuthe ngqo inkqubo yokuphosa isanti. I-Austenitic stainlesses inezinga eliphezulu lokucutheka-zifuna iinkqubo ezikhulayo eziqinileyo ezenziwe ngumntu owaziyo ukuba ukuziphatha kwe-alloy ethile.
Kulapho ukukhankanywa kwe-alloys ekhethekileyo kwimiba yeprofayili yenkampani. Ukuba a inkampani yokugalela isanti idwelisa i-nickel-based okanye ialloys esekwe kwi-cobalt, indixelela ukuba kusenokwenzeka ukuba bajongana nobushushu obuphezulu okanye iinkonzo eziyingozi kakhulu. Cinga amacandelo e-injini ye-injini, ii-impellers zempompo zeekhemikhali eziqatha. Le asiyomisebenzi eqhelekileyo. Ukugalela ezi ngxubevange kufuna ulawulo oluchanekileyo lobushushu, amaxesha amaninzi phantsi kwe-atmospheres ekhuselayo, kunye nekhemistry yokungunda yesanti kufuneka ihambelane ukunqanda ukusabela komphezulu. Yiligi eyahlukileyo ukusuka ekujuleni intsimbi engwevu ye counterweight.
Ndenze impazamo kanye, ndityhalela i-nickel alloy yobunikazi bobushushu obuphezulu kuba iipropathi zeshiti ledatha zazigqibelele. Khange ndidibane nzulu ngokwaneleyo ngeFoundry kuqala. Kwavela ukuba i-alloy yayidume ngokukrazula okushushu kumacandelo ashinyeneyo kunye nenkqubo yesanti abayisebenzisayo. Kuye kwafuneka sibuyele umva, sitshintshele kwibakala elinokugalelwa ngakumbi, kwaye siyiyile ngokutsha iipropathi ezahluke kancinane. Isifundo: ukhetho lwemathiriyeli yingxoxo kunye ne-metallurgist ye-Foundry, hayi isigqibo sobunjineli sodwa.
Iinkcukacha ezingezizo ezenza okanye ezaphula iProjekthi
Ukwenza ipateni. Lixabiso langaphambili wonke umntu afuna ukulinciphisa, kodwa sisiseko sayo yonke into. Ipateni yomthi enexabiso eliphantsi, ephothiweyo iya kuvelisa ukungunda okungahambelaniyo ngonaphakade. Ukuqhuba imveliso, utyalo-mali kwipateni yesinyithi ehlala ixesha elide, enomlinganiselo (ehlala i-aluminiyam okanye intsimbi) ayinakuxoxisana. Kulungile iinkampani zokugalela isanti izakuhamba phambili ngale nto. Basenokulawula ukwenza iipatheni kuwe, nto leyo eyinzuzo enkulu.
Emva koko kukho amaxwebhu asemgangathweni. Ukuphoswa komgangatho worhwebo kunokufumana nje uhlolo olubonakalayo. Icandelo elibalulekileyo lidinga i-cert yezinto eziphathekayo (ingxelo yovavanyo lokugaya), mhlawumbi uvavanyo lwe-radiographic okanye i-ultrasonic yesandi sangaphakathi, kunye neengxelo zokuhlola inqaku lokuqala. Kuya kufuneka wazi ukuba leliphi inqanaba olifunayo kwaye uqinisekise ukuba amandla omthengisi ayahambelana. Ivenkile ekwawenza ngokuchanekileyo machining iqhele ukuseta lo mgangatho wamaxwebhu, njengoko iyinto eqhelekileyo kwiivenkile zemisebenzi yobuchwephesha.
Ixesha lokukhokela ngomnye umqobo osebenzayo. Abantu bacinga ukuba ukuphosa isanti kuyakhawuleza kuba yinkqubo elula. Ukudala iphethini entsha, ukufaneleka kwamanqaku okuqala, ukumisa imigca yokubumba-oko kuthatha ixesha. Ukugalelwa kwangempela kuyakhawuleza. Ucwangciso oluyinyani olusuka kumboneleli oqeqeshiweyo lwenza onke la manyathelo. Isithembiso sexesha leeveki ezimbini zokukhokela kwinxalenye entsha, eyinkimbinkimbi idla ngokuba yiflegi ebomvu.
Ukujonga kwi-Real-World Operation
Makhe sibuyele emva kumzekelo we Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Izakhono zabo ezidwelisiweyo kwi tsngtaocnc.com peyinta umfanekiso wohlobo oluthile lomsebenzi. Bakhankanya iqokobhe ngundo ukuphosa, elinyathelo elingaphezu kwesanti eluhlaza eqhelekileyo ngokwemigaqo yokuchaneka komgangatho kunye nokugqitywa komphezulu. Ihlala isetyenziselwa umthamo ophakathi, amalungu antsokothileyo. Ukudibanisa loo nto utyalo mali (ngokuchaneka okuphezulu ngakumbi) kwaye igcwele CNC Machining icebisa ukuba bajolise kwicandelo lemarike elifuna izinto ezilungele ukuhlohla, hayi izinto ezirhabaxa.
Uluhlu lwazo lwezinto eziphathekayo-ukusuka kwiintsimbi eziqhelekileyo kunye neentsimbi ukuya kwii-alloys ezingaqhelekanga-zibonisa ukusekwa okuguquguqukayo okunyibilikayo, mhlawumbi ii-furnaces ze-induction ezinokutshintsha phakathi kwe-alloys kunye nokucoca okufanelekileyo. Kumthengi, oku kungundoqo. Kuthetha ukuba iprototype yakho iqala ngentsimbi yekhabhoni kodwa kufuneka ihambe iye kwindawo engenasiphene ukuze idle, akunokufuneka ufumane umboneleli omtsha. Banokusingatha olo tshintsho, ukuqonda iimpawu ezahlukeneyo zokuphosa.
I-takeaway xa uvavanya nayiphi na inkampani yokugalela isanti kukukhangela olu hlobo lohlanganiso oluthe nkqo kunye nobubanzi bezinto eziphathekayo. Ayisosiqinisekiso semfezeko, kodwa luphawu oluqinileyo abawuqondayo umjikelo opheleleyo wobomi benxalenye. Baye basombulula iingxaki zolungelelwaniso phakathi kokuphosa kunye nomatshini, kwaye mhlawumbi baye bajongana neentloko zesiqinisekiso sezinto eziphathekayo. Kule ntsimi, imbali eqokelelweyo, esebenzayo yokusombulula iingxaki-uhlobo oluvela kwiminyaka engama-30 yokusebenza-yeyona asethi ibaluleke kakhulu, kwaye wena njengomthengi, unokuba nayo. Ijika ukuthenga okulula kokuphosa kwintsebenziswano yokuvelisa.
