Xa umntu echwetheza 'i-investment casting near me' kwi-injini yokukhangela, ndiyayifumana. Ingcinga ekhawulezileyo imalunga nenkqubo yolungiselelo, iingcaphuno ezikhawulezayo, mhlawumbi utyelelo lwesiza. Kodwa kweli shishini, ukusondela kuhlala kuyeyona nto incinci inomdla kwi-equation. Umbuzo wangempela ongcwatywe kolo phando malunga nokufumana iqabane elingaqondi nje ijometri yenxalenye, kodwa i-physics yokuthulula, i-chemistry yeqokobhe, kunye nokuchasana okungenakuphepheka kwemveliso. Ndibone iiprojekthi ezininzi zisihla ngenxa yokuba ukhetho lwenziwa ngokusekwe kwiphini yemephu endaweni yesakhono sesinyithi. Masithethe ngale nto uyikhangelayo.
Umdlalo weShell: Ngakumbi Kunokuba kufutshane nje
Ngoko, udinga inxalenye. Mhlawumbi yi blade ye turbine, isixhobo sotyando, okanye i-complex pump impeller. Ithuku lakho lokuqala kukufumana indawo. Kodwa 'indawo' yotyalo-mali ayifani nokufumana ivenkile yekofu yasekhaya. Iradiyasi yesiseko esinako sesesizwe, nakwihlabathi jikelele, ukwenzela umsebenzi okhethekileyo. Isitshixo asiyiyo ikhowudi ye-ZIP; lulawulo lwenkqubo yabo. Ndikhumbula umsebenzi wecandelo laselwandle kwi-316L engenastainless. Ivenkile ekwiimayile ezingamashumi amabini ukusuka kude icaphule ixabiso elimangalisayo kunye nomgca wexesha. Indawo yabo yayingenabala. Kodwa bahlala begalela kumaqondo obushushu athi, ngelixa esindisa ixesha leziko, enze ulwelo olusemdeni. Isiphumo? Ukungqinelana, umzuzu obandayo uvala kwiindawo zokuvavanya ezingonakalisi. Inxalenye yayibonakala ilungile kodwa yayiza kusilela phantsi koxinzelelo. Ivenkile yayikufuphi, kodwa indlela ababeziqhelanisa ngayo yayingeyiyo kwaphela.
Apha kulapho uphendlo lokwenyani luqala khona. Awujonganga nje utyalo mali; ukhangela i-Foundry ebuza malunga nomsebenzi wecandelo, iimeko zomthwalo wayo, imeko-bume yayo yomhlwa. Ngaba bayakubuza kwi-alloy spec, okanye bamkele nje inani? Indawo efana neQingdao Qiangsenyuan Technology Co., Ltd. (QSY), umzekelo, idwelisa ngaphezulu kweminyaka engama-30 kubumba lweqokobhe kunye utyalo mali. Obo bomi bude buyinto yedatha. Kolu shishino, ukusinda kumashumi amathathu eminyaka kuthetha ukuba ukhe wajonga kwiibhomu kunye neebhasi, uqhelanise ne-alloys emitsha, kwaye mhlawumbi unolwazi olunzulu lwe-tacit-uhlobo olungekho kwincwadana kodwa lukwisigqibo somphathi malunga namaqondo okushisa angaphambili kwi-alloy esekelwe kwi-cobalt.
Iwebhusayithi yabo, https://www.tsingtaocnc.com, ibonisa uluhlu lwabo: intsimbi etyhidiweyo, intsimbi, i-stainless, kunye nezo zinto zikhethekileyo. Ngumqondiso lowo. Ukuphatha i-nickel-based alloys ayiyonto yomdlalo wecala; ifuna iilayini ezinikezelweyo zeziko, iiprothokholi ezingqongqo zongcoliseko, kunye nengqondo eyahlukileyo. Ukuba ivenkile idwelisa oko, ikuxelela ukuba isebenza kwinqanaba apho imfezeko yezinto eziphathekayo ingaxoxiswana. Itshintsha icalculus 'ekufuphi nam' ukusuka kwijografi ukuya ekubeni kufutshane.
I-Alloy Maze kunye neTrap eLungileyo eyaneleyo
Ukuthetha nge-alloys, nantsi i-pitfall eqhelekileyo. Umyili uxela i-Inconel 718 ngokusebenza kwayo kobushushu obuphezulu. Isiseko, esifuna ishishini kodwa mhlawumbi singenawo amava angaguqukiyo kulo, sinokucebisa ibakala elifanayo ekulula ukuliqhuba. Ngamanye amaxesha oku kuyasebenza. Ngokufuthi, ingenisa ingozi. Umtyholi ukwi-post-casting heat treatment kunye nesiphumo sesigaba sozinzo. Ndifunde oku ngendlela enzima kwangethuba ngendlu yempompo. Savuma ukutshintshwa kwezinto ezidibana nekhemikhali spec ephepheni. Yadlula i-QA yokuqala. Yasilela ebaleni emva kweeyure ezingama-400 zoxinzelelo lwe-thermal ye-cyclic, iqhekeza kumda wengqolowa. Oyena nobangela? Impendulo yealloyi ebambeleyo kumjikelo wesisombululo se-annealing yayahlukile, ekhokelela kwimvula yesigaba se-sigma sangaphambi kwexesha. Isiseko sasingenganyanisekanga; babehleli nje phezu kwentloko yabo.
Kungenxa yoko le nto i-specialization yenkampani ibalulekile. Xa i-QSY idwelisa ngokucacileyo i-cobalt-based and nickel-based alloys, ithetha (okanye kufuneka ichaze) inkqubo elawulwayo kwezi zixhobo ezinzima. Kuthetha ukuba kusenokwenzeka ukuba banenkxaso yelebhu yesinyithi, nokuba bakhutshelwe ngaphandle, ukuqinisekisa hayi nje ikhemistri kodwa ubume be-microstructure. Ngomntu okhangelayo 'utyalo mali kufutshane nam', isifundo kukuphonononga ibango lezinto eziphathekayo. Cela ijiko eliqhelekileyo lokunyanga ubushushu abalisebenzisayo kwi-nickel alloy. Buza ngereyithi ye-scrap yabo kwezo zinto. Iimpendulo ziya kukuxelela ngaphezulu komgama we-metric.
Xa i-CNC Machining Ayiyonto yokucinga
Phantse akukho kutyalomali oluphuma emthini ulungele ukuthunyelwa ngenqanawa. Kukho ukususwa kwesango, ukugqitywa komphezulu, kwaye phantse rhoqo, umatshini obalulekileyo kwiimpawu zedatum. Apha kulapho imodeli edityanisiweyo ye-Foundry efana ne-QSY, edibanisa i-casting kunye ne-CNC machining, ibonisa ixabiso layo. Eyona ntloko inkulu ekusebenzelaneni nabathengisi abahlukeneyo kukuguqulelwa kwedatum. Ivenkile yokuphosa isebenzisa iseti enye yeedatum ukuze ihlolwe. Ivenkile yomatshini kufuneka iphinde iwamisele, kwaye kuloo nkqubo, ukupakishwa kokunyamezela kunokubulala inxalenye.
Ukuba neenkqubo zombini phantsi kophahla olunye, okanye ubuncinane phantsi kwenkqubo enye yolawulo, kunciphisa oku. Oomatshini banokuthetha ngokuthe ngqo kwiinjineli ze-Foundry malunga nomphezulu wokuphosa, iindawo ezinokuthi zithintelwe, kunye nezibonelelo zokunciphisa. Ndiwabonile amaxesha okukhokela esikwa ngeeveki ezintathu ngokulula ngokususa ukuthunyelwa, ukucaphula kwakhona, kunye nokulungiswa kwakhona kwe-loop phakathi kweenkampani ezimbini ezahlukeneyo. Ke, ukukhangela kwakho utyalo mali iinkonzo kufuneka zithathele ingqalelo kakhulu abo banikezela ngomatshini odibeneyo. Asinto nje elula; yijiyometri kunye nenzuzo yokulawula umgangatho.
Jonga kwiphepha labo lomatshini. Ngaba zibonisa i-4-axis okanye i-5-axis isakhono? Ukusaswa okuntsokothileyo okunje ngee-impellers okanye iiblade ze-iturbine, i-3-axis machining kaninzi ayizukuyisika (i-pun ijongiwe). Ukukwazi ukugqiba umatshini ngokuseta enye igcina ijometri yendalo yokusasa kwaye konga iindleko.
IPhepha lokucaphula: Ukufunda phakathi kweMigca
Uya kufumana ikowuti. Iyakuba nexabiso ngeqhekeza ngalinye, ixabiso lesixhobo, kunye nexesha lokukhokela. Uthelekiso olungenangqondo lukula manani mathathu. Ukujonga okunamava kukwenye indawo. Okokuqala, jonga ukuhla kwexabiso lepateni. Ngaba basebenzisa iprototyping ekhawulezayo kwipateni yokuqala, okanye iindlela zemveli? Kwimiqulu ephantsi, oku kubalulekile. Okwesibini, jonga kwiikhrayitheriya zokuhlola ezidwelisiweyo. Ngaba kukushicilela nje, okanye ngaba bachaza iingxelo zokuhlolwa kwenqaku lokuqala, iziqinisekiso zezinto eziphathekayo kwimigangatho ye-ASTM/AMS, kunye neendlela ze-NDT ezifana nedayi yokungena okanye i-X-ray? Igatya lokuhlola elingacacanga yiflegi ebomvu.
Ndikhumbula isicatshulwa esivela kwi-Foundry eyayiyi-15% ephantsi kunelandelayo. Umgca wabo wokuhlola uchaze ngokulula isheke ye-dimensional. Sahamba nabo. Ibhetshi yokuqala yayinemilinganiselo egqibeleleyo. Basilela ekudibaneni ngenxa yokuba ukuguquguquka kodonga, okungazange kubizwe kushicilelo njengomlinganiselo obalulekileyo, kwakuqatha kangangokuba amalungu ayengayi kuhlangana. I-Foundry yayidibene neleta yesicatshulwa. Impazamo yethu yayingacacisi ukuqina kodonga olufunekayo kwiprotocol yokuhlola. Ngoku, ndihlala ndicela iphepha lokuhlola elisemgangathweni. Isiseko esinobuchule siya kuba nesilungisiweyo.
Kumthengisi weenkqubo ezininzi, isicatshulwa kufuneka sicacise kwakhona ukuba i-machining ibandakanyiwe, kwaye ukuba kunjalo, ukugqitywa kweyiphi. Ngaba kukuphosa komatshini, okanye inxalenye egqityiweyo? Oku kucaca kwahlula abadlali abanzulu abathatha i-odolo.
Ukuyibuyisela Kum
Ke, emva kwayo yonke le nto, yenza ntoni 'utyalo mali kufutshane nam'uthetha ukuthini? Iyatshintsha. Iba ngaphantsi malunga nomgama womzimba kwaye ngakumbi malunga nokomelela kwekhonkco lokubonelela, ukukhululeka konxibelelwano, kunye nokulungelelaniswa kobugcisa. Isiseko kwelinye icala lelizwe kunye neqela lobunjineli beenkwenkwezi kunye nonxibelelwano lwedijithali olungenamthungo (uphononongo olucacileyo lweCAD, uhlaziyo lwefoto rhoqo lwenkqubela phambili yepateni) inokuziva isondele kunevenkile yasekhaya ekunzima ukuyibamba.
Nangona kunjalo, ukusondela ngokomzimba kunenzuzo enye engenakuphikiswa: ukuphicothwa kunye nokwakhiwa kobudlelwane. Ukukwazi ukutyelela umgangatho, ubone imigca yegobolondo ye-ceramic, ivumba i-Foundry (i-foundry elungileyo ine-specific, ayiyiyo into engathandekiyo, iphunga-ivumba leenkqubo ezilawulwayo), kwaye ujonge umphathi wekhwalithi kwiso ungabalulekanga. Kwakha ukuthembana. Kulapho inkampani enembali yokusebenza ixesha elide, njengemvelaphi ye-30 yeminyaka ephawulwe kwi-QSY, inikezela ngohlobo lozinzo. Bakhe bekhona. Kusenokwenzeka ukuba bayibonile yonke loo nto.
Uphendlo lwakho, ke ngoko, kufuneka luqale ngesakhono (ialloyi, iinkqubo, ukwenziwa komatshini), hluza ngesakhono esiqinisekisiweyo (i-industry tenure, uluhlu lwabaxumi, imibuzo yobugcisa), kwaye ekugqibeleni, sebenzisa ijografi njengeqhina okanye ibhonasi yokulungiselela. Injongo ayikokufumana oyena caster ukufutshane. Injongo kukufumana elona qabane likwaziyo ukuguqulela ngokuthembekileyo injongo yoyilo lwakho lube yinto esebenzayo, eyomeleleyo yentsimbi. Elo qabane linokuba ziikhilomitha ezingama-200 okanye iimayile ezingama-2,000. Kodwa xa ubafumene, ubuchule babo buya kubenza bazive bengummelwane ofanelekileyo kulo msebenzi.
