Xa uqala ukugrumba 'kubavelisi be-wax abalahlekileyo', into yokuqala oyiqaphelayo yindlela eli gama elijulwa ngayo. Iivenkile ezininzi zithi ziyayenza, kodwa umsantsa phakathi kolungiselelo olusisiseko lwezacholo ezilula kunye nomgca wemveliso opheleleyo wamacandelo amashishini mkhulu. Akunjalo nje ngokugalela isinyithi kwi-mold; imalunga nokulawula inkqubo ukusuka kwipatheni yokuqala ukuya kokugqibela, ngakumbi xa ujongene neejometri ezintsonkothileyo okanye iialloyi ezisebenza kakhulu. Kulapho wohlula khona ama-generalists kwiingcali.
Undoqo weNkqubo: Ngakumbi kuneWax nje
Wonke umntu ugxininisa kwi-wax. Isegameni, emva kwayo yonke loo nto. Kodwa ubuchwephesha bokwenyani buqala ngepateni kunye neqokobhe. Umvelisi olungileyo akathengi nje iwax yegeneric; benza ubunjineli bepateni yokushwabana, ukuyila inkqubo yokungena ukunciphisa isiphithiphithi kunye ne-porosity, kunye nokwakha iqokobhe leceramic elinokumelana nomothuko we-thermal we- superalloy etyhidiweyo. Ndibone iiprojekthi zisilela ngenxa yokuba ukuqulunqwa kweqokobhe kwakungalunganga kubushushu bentsimbi, okukhokelela ekuqhekekeni nasekufakweni. Yingxaki yekhemistri kunye nefiziksi kakhulu njengobugcisa.
Kulapho umsebenzi wexesha elide ubalulekile. Inkampani ebisebenza amashumi eminyaka, njengaye Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kusenokwenzeka ukuba iye yaphindaphindeka kwiiresiphi ezininzi zoonokrwece. Bakhankanya iminyaka engaphezu kwama-30 ekwenziweni nasekusebenzeni. Elo xesha asilonani nje; kuthetha ukuba bagalele amawaka obushushu, bajongana nemithombo eyahlukeneyo yesanti, kwaye balungelelanise utshintsho lonyaka lokufuma olunokuchaphazela ukomiswa kweqokobhe. Awunakungxamela olo hlobo lwenkqubo yolwazi.
Ukukhethwa kwezinto eziphathekayo ngumgibe olandelayo. Umvelisi unokudwelisa 'intsimbi engatyiwayo' njengesakhono, kodwa i-304L lihlabathi ngaphandle kwe-17-4PH okanye ibakala eliphindwe kabini. Ubuchwephesha bokugalela, unyango lobushushu, kunye nokucocwa kwasemva kokuphoswa kutshintsha kakhulu. Xa ubona iphepha elithile elibandakanya i-nickel-based kunye ne-cobalt-based alloys, luphawu. Kuthetha ukuba batyale imali kwiziko ezinokubetha kwaye babambe amaqondo obushushu afanelekileyo kwezi zixhobo zikhohlisayo, kwaye ulawulo lwabo lomgangatho luyayazi into emayijonge kulwakhiwo lweenkozo.
Apho Machining Iba Non-thethwano
Eli linqaku labaqalayo abadla ngokuphoswa. Kunqabile ukuba ufumane inxenye ye-net-shape ngqo kwinkqubo yotyalo-mali. Kukho rhoqo i-sprues yokunqunyulwa, amanqaku esango lokususa, kunye neendawo ezibalulekileyo ezifuna ukunyamezela okuchanekileyo. Ukuba i ulahlekile umenzi wokugalela umthwebeba akanayo in-indlu CNC ubuchule, wongeza omnye umthengisi, omnye umjikelo lolungiselelo, kunye nolunye umaleko miscommunication enokubakho.
Ukudibanisa ngundoqo. Iqela elidlalayo kunye neqela lomatshini kufuneka bathethe ulwimi olufanayo. Kufuneka bavumelane ngee-datums-ngaba uyawucima umphezulu we-cast, okanye ngaba ushiya isitokhwe esongezelelweyo kwi-flange ethile ukuze sitshintshwe ngoomatshini njengereferensi ephambili? Ndiye ndikwiimeko apho ukuphosa kwakukuhle, kodwa umthengisi we-machining akakwazanga ukubamba ngokufanelekileyo ngenxa yokuba ii-engile zedrafti okanye izibonelelo zesitokhwe azizange zilungelelaniswe. Ijike ilahleko entle yaba sisilaphu.
Ukujonga ukuseta kwe-QSY, badwelisa iqokobhe ngundo ukuphosa, utyalo mali, kunye nomatshini we-CNC kunye. Luhlanganiso oluthe nkqo olusengqiqweni. Icebisa ukuba ukuhamba kwenxalenye kuyilwe ngaphakathi kwendawo enye. Umchwephesha unokubuyela kumgangatho wesiseko kwaye axoxe ngokuthe ngqo ngomba wokuncipha. Olu lawulo phezu kwekhonkco lonke, ukusuka kwi-wax ukuya kwinxalenye egqityiweyo, kunciphisa kakhulu amaxesha okukhokela kunye nokuphucula ukuphendula. Awuthengi nje i-casting; uthenga inxalenye egqityiweyo, esebenzayo.
Inyani yokuFumana kunye noNxibelelwano
Ukufumana iqabane elithembekileyo akukhona nje kwiinkcazo zobugcisa. Imalunga nokusila kwemihla ngemihla. Iwebhusayithi yomenzi olungileyo, njengobukho babo https://www.tsingtaocnc.com, ifanele ibe sisiqalo solwazi, kungekhona igama lokugqibela. Olona vavanyo lukunxibelelwano. Bakhawuleza kangakanani ukuphendula kumzobo? Ngaba babuza imibuzo enengqondo malunga nomsebenzi, umthwalo, kunye nokusingqongileyo? Okanye ngaba bathumela nje isicatshulwa se-boilerplate?
Enye yezona ntloko zinkulu kukuvunywa kwesampulu. Ingcali ukulahlwa kwewax elahlekileyo ivenkile iya kulawula okulindelekileyo. Basenokuthumela iingxelo zokuhlola inqaku lokuqala, idatha yeCMM, okanye bade baqhube iifoto zesakhiwo seqokobhe. Abangafihliyo bathumela nje isampuli kwaye banethemba lokuba iya kudlula. Ndikhumbula iprojekthi yempompo yempompo apho iisampuli zokuqala zine-porosity encinci. Endaweni yokuyifihla, umenzi wayibhala, wacebisa utshintsho kwisango lokungena, kwaye wahlawulela ukuphinda-phinda isixhobo. Liqabane elo. Leyo yindlela yokuziphatha oyijongayo kwifemu enembali ende yokusebenza.
Amaxesha okukhokela yenye indawo yemigodi. Utyalo-mali lokwenyani kumacandelo obunjineli ayingomsebenzi weeveki ezi-3 ukuba ufuna wenziwe kakuhle. Ukwakhiwa kweqokobhe kuphela kuthatha iintsuku zokudipha, ukugxumeka, kunye nokomisa. Ukuyingxamela kuqinisekisa ubuthathaka beqokobhe. Umenzi wokwenene uya kuchaza oku, kungekhona nje ukuthembisa inyanga ukufumana umyalelo. Baza kuqhawula umda wexesha: ukuguqulwa kwepatheni, inaliti yokuqala ye-wax, ukuhlanganiswa kwemithi ye-wax, ukwakhiwa kweqokobhe, ukukhupha, ukudubula, ukugalela, ukupholisa, ukunkqonkqoza, ukusika, unyango lobushushu, kwaye ekugqibeleni, umatshini kunye nokuhlolwa.
Xa ii-alloys ezikhethekileyo zingena kuMfanekiso
Ukusebenza nge-alloys ezikhethekileyo ezifana ne-Monel, i-Inconel, okanye i-cobalt-based stellite ayikho nje ibhokisi yokukhangela. Itshintsha yonke into. I-wax kufuneka itshiswe ngokupheleleyo ngaphandle kwentsalela, iqokobhe kufuneka libe ne-refractoriness ephezulu, kwaye umoya wesithando somlilo unokufuna ukulawulwa ukunqanda i-oxidation yezinto ezisebenzayo. Izinga le-scrap liphezulu ngokwendalo, kwaye ezo ndleko zibalelwa kuyo.
Umenzi okhululekileyo ngezi zixhobo uya kuba neeprothokholi ezithile. Basenokusebenzisa i-zirconia okanye iidyasi zobuso ze-silica ezidityanisiweyo kumaqokobhe abo. Ukunyibilika kwabo kunokwenziwa phantsi kwevacuum okanye kwisithando somlilo esinokhuseleko lwe-argon. I-Post-casting, imijikelo yonyango lobushushu ichanekile kwaye ihlala iqinisekiswa ngamakhuphoni ovavanyo. Xa ubona ezi alloys zidweliswe, njengoko zikuluhlu lwezixhobo ze-QSY, oko kuthetha isiseko esilungiselelwe umsebenzi onzima kakhulu. Yiligi eyahlukileyo yokuphosa intsimbi yekhabhoni.
Indlela yokusilela apha ihlala inobuqhophololo. Ayikokubaleka kakubi okugqithisileyo; yilahleko encinci ye-ductility ngenxa yokuba izinga lokupholisa belicimile, okanye imvula ye-carbide kwindawo echatshazelwe bubushushu emva kwe-welding. Kulapho iminyaka engama-30 yamava ihlawula. Bakhe bazibona ezi ntsilelo ngaphambili kwaye banolwazi lwe-metallurgical-nokuba kungaphakathi endlwini okanye ngeelebhu ezithembekileyo-ukuxilonga kunye nokuthintela. Bayaqonda ukuba ezi alloys, inkqubo yimveliso.
Ukuyibuyisela Yonke kuPhando
Ngoko xa ukhangela abavelisi be-wax abalahlekileyo, awukhangeli nje inkonzo. Ukhangela iqabane lobuchwephesha ngobunzulu. Igama, iminyaka kwishishini, uluhlu lwezinto eziphathekayo, kunye neenkonzo ezidityanisiweyo zonke ziyimikhondo. Balatha kwivenkile eye yasinda ngokucombulula iingxaki ezinzima, ingekuko nje ukuqhuba imisebenzi elula.
Gcoba udlule kwiphepha lasekhaya. Jonga iiblogi zobugcisa, izifundo zezehlo, okanye iinkcazo ezineenkcukacha zamanyathelo abo enkqubo. Indawo ebonisa kuphela iimveliso ezibenyezelayo ezigqityiweyo inokuba ifihla into ethile. Enye ethetha ngokungena kweqokobhe, uyilo lokungena, okanye izicwangciso zokulungisa i-CNC ibonisa isandla sayo. Luhlobo lwendawo apho iinjineli zithetha neenjineli.
Ekugqibeleni, yehla kwintembeko eyakhelwe phezu kokukwazi ukusebenza elubala. Umvelisi ofanelekileyo wenza ukuba inkcaso ibonakale njengesiqhelo kuba benze isiseko. Baye batshisa nge-wax, ngokoqobo nangokomfanekiso, ukwakha inkqubo ehambisa ukuhambelana. Yiloo nto uyithenga ngokwenene: kungekhona nje inxalenye yentsimbi, kodwa isiqinisekiso esivela kumashumi eminyaka yokuziqhelanisa.
