Xa usiva 'iindawo ze-Inconel alloy,' umfanekiso ongoko nangoko udla ngokuba ngomnye wamalungu angonakaliyo kwiinjini zejethi okanye iirigi ezinzulu zolwandle. Akunjalo, kodwa yinto elula ekhokelela kwi-pitfall yokuqala enkulu kweli shishini: ukuphatha zonke ii-Inconel njengokuba 'ziyintsimbi enzima ye-nickel.' Ndibone iiprojekthi ezininzi kakhulu ziyakhubeka kuba umntu spec'd 718 kwisicelo esilungele ngcono i-625, okanye okubi nakakhulu, wazama ukuyimatshini njenge-304 engenasici. Umtyholi, njengamaxesha onke, kwiinkcukacha-imbali ye-thermal, iimfuno ze-post-processing, kunye nenyaniso ecacileyo, enenkani ye-chip kwisixhobo sakho sokusika.
I-Material ayiloPhepha nje eliKhethekileyo
Ukusebenza ngala ma-alloys, ngakumbi Amalungu e-inconel alloy ezimiselwe iindawo ezinoxinzelelo oluphezulu, kuthetha ukuqonda ukuba banenkumbulo. Iimpawu zomatshini ozifumanayo zibotshelelwe ngokuthe ngqo kwikhonkco lenkqubo. Umzekelo, kunye ne-Inconel 718, ulandelelwano olunzima emva kokwenziwa komatshini alunakuxoxisana ukuze kuzuzwe amandla esivuno aziwayo. Tsiba okanye uyilahle loo nto, kwaye inxalenye inokudlula i-QA yokuqala kodwa ingaphumeleli ngokumangalisayo ebaleni phantsi kokulayisha umjikelo. Asiyonto yorhwebo oyi-odolayo ngokwesayizi.
Kulapho i-30-plus iminyaka ye-Foundry kunye nevenkile yomatshini efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ibaluleke ngokwenene. Ayikokuba nesakhono esidweliswe kwiwebhusayithi; imalunga nolwazi oluqokelelweyo, oluphantse lube lula malunga nendlela i-alloy eziphatha ngayo ukusuka kwisimo esinyibilikisiweyo. utyalo mali qhubekeka ukuya kupasi lokugqibela lweCNC. Awunakuyenza loo nto. Umsebenzi wabo wexesha elide, onokuwubona ngokweenkcukacha https://www.tsingtaocnc.com, icebisa ukuba baye bahamba kwi-curve yokufunda yokulawula ukwahlula kwii-alloy castings ezinkulu ezisekelwe kwi-nickel-intloko eqhelekileyo ejika i-premium material ibe yi-scrap.
Ndikhumbula imeko yeringi ye turbine yokutywina. Ushicilelo lubize i-Inconel 738, njenge-cast kwaye yenziwe ngoomatshini. Ukuqhuba kokuqala okuvela kumthengisi owahlukileyo kuneendawo ezilukhuni ezingahambelaniyo, ezikhokelela ekunxibeni okungalinganiyo. Umba ulandelelwe emva kumazinga okupholisa angalinganiyo kubumba lweqokobhe. Ukulungiswa kwakungeyonto nje yokulungisa oomatshini; kwakudinga ukuphinda kuqwalaselwe isango lokungena kunye noyilo lokunyuka kwinqanaba lokuphosa ngokwalo-imbono epheleleyo eyahlula abenzi beengxenye kwiiprosesa zezinto.
Machining: Apho Ithiyori idibana neSixhobo esaphukileyo
Olu luvavanyo lokwenyani. Nabani na unokwenza ibango lomatshini we-CNC kwii-alloys ezikhethekileyo. Ukuyizisa ngenzuzo kwaye ngokuchanekileyo lelinye ibali. Isantya esiphezulu sokusebenza nzima kwee-alloys ezifana ne-Inconel 625 kuthetha ukuba isicwangciso sakho sokusika siyinto yonke. Ukukhanya, ubunzulu obuguquguqukayo bokusikwa, amazinga okutya okunobundlongondlongo okungena phantsi komgangatho owenziwe lukhuni, kunye neendlela eziqinileyo zesixhobo ziyivangeli. Uthandabuza, okanye uvumele isixhobo sihlale, kwaye udale nje indawo yobulukhuni bendawo eya kudla ukufakwa kwakho okulandelayo.
Isipholisi asenzelwa ukupholisa nje apha; yeyokuthambisa kunye nokukhupha itshiphu. Uxinzelelo oluphezulu, isixhobo sokupholisa ngesixhobo siphantse sibe sinyanzelo kumsebenzi onzulu womgodi. Sifunde oku ngendlela enzima kwibhetshi yeerotha ezidibeneyo (ii-blisks) prototypes. I-Chip welding ibangele ukusilela kwesixhobo kwisiqingatha somjikelo womatshini wokwenza iiyure ezingama-40 kwiforging enye. Iindleko yayingezozixhobo nje; yayilixesha elilahlekileyo kumatshini kunye nomngcipheko womsebenzi owenziwe ngaphambili. Ngoku, ukubeka iliso kubomi besixhobo kunye namabakala athile e-ceramic okanye e-carbide abhakwa kwisicwangciso sayo nayiphi na ialloys esekwe nickel umsebenzi.
Kukwezi meko ukuba ifilosofi machining iqabane ibonisa. Ivenkile ewuthatha 'njengomsebenzi owodwa' kwaye ilungelelanise iiparamitha zabo ezisemgangathweni kuya kuba nzima. Ivenkile efana ne-QSY, ejolise kuyo ngokucacileyo CNC Machining kwezi zixhobo zinzima, kusenokwenzeka ukuba umisele ulungelelwaniso loomatshini, iilayibrari zeparameter, kwaye, kubaluleke kakhulu, abasebenzi abanamava abasaziyo isandi kunye nokuziva kokusikwa okuhamba kakuhle.
Isiseko sokuCasa: Ayizizo zonke 'ii-Castings ezichanekileyo' ezilinganayo
Amalungu amaninzi aqala njengokuphosa, kwaye le yifolokhwe ebalulekileyo endleleni. Ukwenziwa kobunjwa beqokobhe kwaye utyalo mali zombini zikuluhlu lwe-QSY, kwaye ukhetho luchaphazela kakhulu umsebenzi osezantsi. Kwiindawo ezintsonkothileyo, ezinodonga olucekethekileyo lwe-Inconel ezineepaseji ezintsonkothileyo zangaphakathi, utyalo-mali luyinkosi. Ikunika i-advanteji ekufutshane ne-net-shape, ukunciphisa isixa sezinto ezixabisa kakhulu, ezinzima kumatshini ekufuneka uzisuse.
Kodwa 'near-net-shape' sisithembiso ekunzima ukusigcina. Ukunyamezelwa kweDimensional kwi as-cast Inconel part kuchatshazelwa bubushushu bomngundo, iqondo lobushushu lokugalela, kunye nepateni yokushwabana kokuqina kwealloyi. Ndibone ibhetshi yemizimba yevalvu apho ubukhulu beflange njenge-cast-cast yahluka ngokwaneleyo ukulahla ukulungiswa kwe-CNC okuzenzekelayo, okubangela usuku olupheleleyo lokuphinda kusetyenzwe kunye nokuhlelwa kwakhona. Isisombululo ibilulawulo olungqongqo lwenkqubo kwisiphelo esingaphambili kunye nokuyila isisitho kunye nokuthotyelwa kwe-op yokuqala yomatshini ukuseka idatum ethembekileyo.
Umgangatho we-cast surface yenye into efihliweyo. Umphezulu ohlwempuzekileyo one-micro-porosity okanye inclusions iba sisiqalo somatshini wakho. Usenokucwangcisela isibonelelo sesitokhwe esiyi-0.5mm, kodwa ukuba i-0.2mm yokuqala izele ziindawo eziqinileyo ezisuka kumphezulu oxidation, isixhobo sakho sikuhambo olugwenxa. I-Foundry efanelekileyo iya kubandakanya inkqubo yokugqiba njengokugaya i-vibratory okanye i-pickling elawulwayo ukuze ibonise indawo ehambelanayo, isandi kwivenkile yomatshini-ngokufanelekileyo phantsi kophahla olulodwa ukuphepha ukukhomba iminwe.
Ukuwelda kunye nokulungiswa: Ububi obuyimfuneko
Ngamanye amaxesha, ngaphandle kwemizamo engcono, inxalenye ifuna ukulungiswa emva komatshini, okanye iyilwe njenge-weldment. I-Welding Inconel yinto ekhethekileyo kuyo. Inkxalabo ephambili kukuthintela ukuqhekeka okutshisayo kunye nokugcina ukuxhathisa kwe-corrosion kwindawo echaphazelekayo ngubushushu (HAZ). Ifuna iimeko ezicoceke kakhulu, iintsimbi ezithile zokugcwalisa (ihlala idityanisiwe njenge-625 yokuzalisa isiseko se-718), kunye nolawulo olucokisekileyo lobushushu obuphakathi.
Isifundo esisebenzisekayo: sakha kwafuneka silungise isingxobo esixhonywa ngoomatshini kwindlu enkulu engama-718. Iqondo lokushisa langaphambili kunye ne-interpass temp lilawulwa ngokugqibeleleyo, kodwa umjikelo wonyango wobushushu osemva kwe-weld (PWHT) uye wakhawuleza. Umphumo waba luxinzelelo olushiyekileyo olwathi kamva lwabangela ukugqwetheka ngexesha lomsebenzi wokugqibela okruqulayo, kwachithwa inxalenye. I-takeaway yayikukuba inkqubo ye-welding, kubandakanywa ne-PWHT, ayisosongezo; yinxalenye ebalulekileyo yolandelelwano lwemveliso kwaye kufuneka icwangciswe kwaye ilungiselelwe ngokufanelekileyo.
Le yenye indawo apho ukuhlanganiswa ngokuthe nkqo kunceda. Ukuba iziko elifanayo elenza ukuphosa kunye nomatshini likwanabo ubuchwephesha bobunjineli beweld, yonke inkqubo ukusuka kukhetho lwemathiriyeli ukuya kwisiqabu sokugqibela soxinzelelo sinokulungelelaniswa. Ithintela ingxaki 'engaphaya kodonga' apho isisombululo sesebe elinye sidala intloko ebuhlungu kwelilandelayo.
Umlinganiselo Wokwenyani: Ukungqinelana kuMqulu
Ukwenza iprototype enye Amalungu e-inconel alloy icela umngeni. Ukwenza amashumi amahlanu okanye ikhulu akwi-spec kwaye enze ngokufanayo luphawu lokwenyani. Apha kulapho amaxwebhu enkqubo kunye neenkqubo zolawulo zihlawula khona. Kumalunga nokuphindaphinda: ukubunjwa kwesanti efanayo kwi-molds, iphrofayili efanayo ye-thermal ye-furnaces yonyango lobushushu, izicwangciso ezifanayo ze-toolpath kunye nokunxiba imibundu kumgangatho we-CNC.
Kwinkampani efana ne-Qingdao Qiangsenyuan Technology Co., Ltd., amashumi eminyaka abo ekusaseni nasematshinini kusenokwenzeka ukuba bazakhele ezi nkqubo, rhoqo ngolingo nangempazamo. Isingeniso sewebhusayithi yabo sikhankanya umsebenzi kunye ialloys esekwe cobalt kwaye ialloys esekwe nickel, endixelela ukuba mhlawumbi banenkxaso ye-metallurgical kunye neelebhu zokuvavanya endlini okanye zidibene ngokuqinileyo. Oko kubalulekile kwisatifikethi sebhetshi kunye nokulandeleka, okungaxoxiswana ngayo kwi-aerospace, amandla, okanye izicelo zonyango.
Ekugqibeleni, iinxalenye eziyimpumelelo ze-Inconel azikho nje ngokuba ne-5-axis mill okanye i-vacuum induction furnace. Kumalunga nolwazi oluqokelelweyo, ngamanye amaxesha olubuhlungu, lwendlela izinto ezihamba ngayo, ezisabela ngayo, kwaye ziyasilela kwinyathelo ngalinye ukusuka kulwelo ukuya kwinxalenye egqityiweyo. Yincoko phakathi koyilo, isayensi yezinto, kunye nepragmatism yomgangatho wevenkile. Yiloo nto uyifunayo ngokwenene kumthengisi-hayi nje uluhlu lwezixhobo, kodwa ubungqina bencoko ephumelele nzima yenzekile, ngokuphindaphindiweyo, iminyaka.
