Xa abantu abaninzi besiva 'icustom metal casting', bafanekisela inguqulelo elula ukusuka kwifayile yeCAD ukuya kwinxalenye egqityiweyo. Yeyokuqala, kwaye inkulu, ukungaqondi kakuhle. Ayingomatshini wokufotokopa. Luthethathethwano phakathi kwenjongo yoyilo kunye nomthetho wenyama, apho ukuziphatha kwezinto eziphathekayo, amandla e-thermal, kunye nobunzima bentsimbi etyhidiweyo zinelizwi lokugqibela. Ndibone uyilo oluninzi oluyinjineli entle luhlala kumgangatho wevenkile kuphela ukuveza iziphene ezisisiseko zokuvelisa umthamo-undercuts ezibamba ii-cores, iinguqu zobukhulu bodonga eziqinisekisa ukushrinkage porosity, okanye umgangatho wobuhle ochazwe kwiialloys ezibulala ukugqiba. Icandelo 'lesiqhelo' alikho malunga nokwenza imilo eyodwa; imalunga nokwenza yonke inkqubo, ukusuka kwindlela yokungena ukuya kunyango lobushushu, ukwenza loo milo isebenze. Iqala ngokuqonda into oyicelayo ukuba yenziwe yintsimbi.
I Foundry Floor Reality Check
Masithethe ngenkqubo yokubumba iqokobhe, enye yeendlela zethu eziphambili kwi-QSY. Ihlala ifakwe kwi-investment casting, kodwa inyaniso emgangathweni i-grittier. Wakha iqokobhe leceramic elijikeleze i-foam okanye ipateni yewax, umaleko ngokomaleko. Ukuchaneka kulungile, kodwa ubugcisa bokwenyani bukwi-slurry viscosity kunye nobungakanani bengqolowa yesanti ye-stucco. Yenze iphosise, kwaye iqokobhe mhlawumbi ayinawo amandla okuphatha ukugalela okanye ayingeneli kangangokuba ibambe iigesi, ikhokelela kwimingxuma yokuvuthela. Ndikhumbula ibhetshi yezindlu zempompo yentsimbi engatyiwayo kwiminyaka embalwa edlulileyo. Uyilo lwalunemijelo enzulu, imxinwa. Amaqokobhe akhangeleka egqibelele ephuma kwindawo yokomisa, kodwa ngexesha lokugalelwa, safumana iqokobhe eliyintlekele lokuqhekeka. Ingxaki yayingeyontsimbi; yayikukuba iqokobhe le-thermal shock resistance ayikwazanga ukumelana nokufudumeza okukhawulezileyo, okungalinganiyo kwijiyometri. Kwafuneka sibuyele emva, silungise ukuqulunqwa kwe-binder, kwaye sinciphise izinga lokuqala lokuthulula. Yongeza indleko kunye nexesha umxhasi engazange alilindele, kodwa yayiyiloo nto okanye ilahle yonke into.
Kulapho i-30 iminyaka yokusebenza i-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ithetha ngayo. Ayilonani nje; yilayibrari yengqondo kwezi ntsilelo kunye kufutshane-eziphosayo. Uhlakulela ukuziva. Xa umzobo omtsha ungena ukuphoswa kwentsimbi yesiko, awujongi nje imilinganiselo. Ulinganisa ngengqondo ukuzaliswa, ipateni yokuqinisa, apho iindawo ezishushu ziya kuba khona. Ujonge laa flange ibhityileyo eqhagamshelwe kumphathi omkhulu kunye nokucinga, Oko kuya kutsala kwaye kurhwebe ngaphandle kokuba sihlengahlengise ukupholisa. Esi sigwebo sangaphambili siso esahlula inxalenye edlula i-QC kwenye eyenza ngokuthembekileyo kwintsimi.
Ukukhethwa kwezinto eziphathekayo yenye indawo yemigodi. Iiklayenti zihlala zisilela ukuya kuma-304 angenastainless ukuxhathisa umhlwa. Kodwa kumalungu afuna ukomelela okuphezulu kunye nokumelana nokunxiba kumaqondo obushushu aphakamileyo, njengezinto ezithile zeinjini yomoya, lukhetho olungalunganga olo. Kuye kwafuneka sikhokele abathengi kwii-alloys ezikhethekileyo, njenge-nickel-based okanye i-cobalt-based alloys. Ezi zirhamncwa ezahlukeneyo ngokupheleleyo. Iimpawu zabo zokunyibilika zahlukile, zithanda ukukrazuka kushushu, kwaye zifuna imigaqo ethile yonyango lobushushu. Ukuzicutha kamva, esikwaphatha ngaphakathi kwindlu kunye necandelo lethu le-CNC, kufuna izixhobo ezikhethekileyo kunye nokutya / isantya. Ingongoma ikukuba, ukwenza ngokwenyani kuthetha ukulungelelanisa iipropathi zendalo zealloyi kunye neemfuno zokusebenza kwenxalenye ukusuka kwincoko yokuqala.
Ukwenziwa koTyalo-mali: Ukuchaneka ngokuBambisa
Ngoku, ngobunzima bokwenyani kunye nokugqitywa komphezulu, siya kwi-investment casting (i-wax elahlekileyo). Apha kulapho ufumana khona ezo ndawo zikufutshane-netha-zemilo ngoyilo oluncinci. Kodwa 'ubuncinci' ayingo 'zero'. Kusafuneka ndiyicacise loo nto kubayili. Ipateni yewax ngokwayo kufuneka itsalwe kwidiyiti yentsimbi, ngoko kukho ii-engile zokuyila rhoqo, nokuba zinesiqingatha sesidanga. Enye into yokubambisa ngundoqo weceramic. Kwiipaseji zangaphakathi, udinga i-core enokumelana nokugalelwa kwesinyithi kodwa emva koko ikhutshwe ngekhemikhali emva koko. Ukuyila ingundoqo eyomelele ngokwaneleyo kwaye isuswe yi-sub-specialty ngokwayo. Sakha sasebenza ngeendlela ezininzi kunye namajelo angaphakathi anqumlanayo. Ijiyometri engundoqo yayibuthathaka kangangokuba yayihlala iqhekeka ngexesha lokutofa nge-wax. Isisombululo sasibandakanya ukuyila kwakhona ingundoqo kunye neenkxaso zangaphakathi eziza kuchithwa kamva, zongeza amanyathelo kunye neendleko. Isicatshulwa sokuqala somthengi sasisekelwe kwinkqubo eqhelekileyo; iindleko zokugqibela zibonise ubunzima bokwenene.
Oku kuzibophelela kwinkonzo ehlanganisiweyo ye-QSY ebonelela ngayo. Ngenxa yokuba siziphatha zombini ukuphoswa kwentsimbi yesiko kunye noomatshini beCNC abalandelayo phantsi kophahla olunye, sinenzuzo ebalulekileyo. Sinokuyila inkqubo yokuphosa sicinga ngomatshini. Mhlawumbi songeza isitokhwe esincinci esongezelelweyo (isibonelelo sokugqiba) kubuso obuthile bedatum ukuze siqinisekise ukuba umachini unomgangatho ococekileyo, ofanayo wokubambelela kuwo. Okanye singacebisa ukutshintshwa komgca wokwahlula ngeemilimitha ezimbalwa ukunqanda ukuba utyhutyhe kwindawo ebalulekileyo yokutywina efuna isiphelo esigqibeleleyo. Le ntsebenziswano ayikho ithiyori; ikhusela intloko ebuhlungu ezantsi komsinga. Inxalenye edlala kakuhle kodwa ayinakubanjwa ngokukhuselekileyo kwi-CNC vise yinxalenye engaphumeleliyo.
Ulawulo lomgangatho yingxelo, hayi umfanekiso okhawulezayo. Ingxelo yovavanyo lwe-tensile ikunika inani, kodwa ayikuxeleli ukuba kutheni ibhetshi yamalungu entsimbi etyhidiweyo ibonise ukwahluka kobulukhuni. Kufuneka ulifunde ibali. Ngaba ibikukuguquguquka okuncinci kwikhabhoni elingana nenyibiliko? Ngaba isantya sokupholisa kwindawo yokushukuma sahlukile ngenxa yokuba umthwalo ubupakishwe ngokungqongqo? Singena ezi parameters ngokugqithisileyo. Ukuqhuba okutsha nje kwezibiyeli zentsimbi, silandele umkhondo weqondo lobushushu lokugalela, ixesha lokupholisa emva kokupholisa, kunye nomjikelo ochanekileyo we-oveni ochanekileyo wepalethi nganye. Xa umthengi ecela umkhondo wophicotho, sinokubonelela ngomnombo opheleleyo wamalungu abo. Nantso ubunzulu bolawulo lwangoku ukuphoswa kwentsimbi yesiko iimfuno.
Xa Iindlela Ezikhethekileyo Ziyingxaki
Ukusebenza ngee-alloys ezikhethekileyo, njengalezo ezisekwe kwi-nickel esihlala siziqhuba, luhambo oluqhubekayo kulawulo lomqobo. Ezi alloys zikhethwa kwiindawo ezigqithiseleyo-ukushisa okuphezulu, ukubola okuphezulu, uxinzelelo oluphezulu. Kodwa iipropati zabo zenza kube nzima ukuphosa. Zineendawo eziphezulu zokunyibilika, oku kuthetha ukuhlaselwa kwe-thermal enobudlova kwizinto zokubumba. Bahlala benoluhlu olumxinwa lokukhenkceza, oku kuthetha ukuba bahamba ukusuka kulwelo ukuya kwisiqina ngokukhawuleza, nto leyo inokukhokelela kwimitruns ukuba isango lokungena alenziwanga ngokugqibeleleyo ukugcwalisa ukungunda ngokukhawuleza nangokubhuduzela.
Ndikhumbula iprojekthi ebandakanya isitulo sevalve esekwe kwi-cobalt kwishishini leoli kunye negesi. I-alloy yayinganyangeki ngendlela emangalisayo, kodwa yayikwathandeka kwisiphene esibizwa ngokuba yi-freckling - ulwahlulo lwekhemikhali lwasekhaya olubonakala njengamabala kwi-macro-etch. Unobangela? Ucotha kakhulu izinga lokuqina. Kwafuneka siphinde siyilwe ngokutsha ngokugodola okungakumbi—ubhedu okanye ukufakwa kwentsimbi okufunxa ubushushu kwiindawo ezithile—ukuze inyanzele intsimbi ukuba yomelele ngokukhawuleza nangokufanayo. Kuthathe iisamente ezininzi zokulinga, ukwahlula kunye nokufaka iisampuli ngexesha ngalinye, ukufumana indawo ebandayo kunye nobukhulu obuchanekileyo. Oku akukho kuyo nayiphi na incwadi yokudlala eqhelekileyo; iyaphindaphinda, ukusombulula ingxaki ngezandla.
Into ethathwa apha kukuba ukucacisa imathiriyeli yeprimiyamu akukuniki ngokuzenzekelayo inxalenye yeprimiyamu. Ifuna isiseko esiyaziyo indlela yokudibanisa loo mathiriyeli ukuba imile. Ifuna iinkqubo ezifana nokunyibilika kwevacuum okanye umoya okhuselayo ukugalela ukuthintela i-oxidation. Ifuna i-post-casting HIP (i-Hot Isostatic Pressing) ukuvala nayiphi na i-micro-porosity eseleyo. Xa ujonga izakhono ezidweliswe kwindawo efana ne-https://www.tsingtaocnc.com, uluhlu lwemathiriyeli kunye neenkqubo ayisiyomenyu nje. Sisishwankathelo seseti yobuchule obuqokelelweyo, obuphumelele nzima ekuphatheni nganye kwezo ntsapho eziphathekayo.
I-Handoff yoMatshini: Apho iNjongo yokuCasa idibana nezixhobo zokusika
Kulapho iivenkile ezininzi ezidibeneyo ziwela khona. Isebe lokuphosa lihambisa inxalenye eza kushicilelwa, kodwa isebe lomatshini liyiphatha njengeqhekeza le-billet stock. Abaluthatheli ngqalelo uxinizelelo lwendalo lokuphosa, ukubakho kwamabala aqinileyo ukusuka ekupholiseni okungalinganiyo, okanye umphumo wolusu (umaleko wangaphandle wokuphosa udla ngokuba ne-microstructure eyahlukileyo). Siyakuphepha oku ngokuba nomsebenzi oqhubekayo. Injineli enye eyongamela ukulinganisa ukuqinisa ukulinganisa iya kuhlala inxibelelana nesicwangciso somatshini we-CNC.
Umzekelo osebenzayo: ukulungisa ubuso obunyukayo kwintsimbi yentsimbi. Ukuba uthatha inxeba elibukhali kakhulu kwipasi lokuqala, ungaligqwetha elo candelo ngokuthomalalisa uxinzelelo lwangaphakathi ngokulinganayo. I-machinist kufuneka ikwazi ukuthatha i-lighter, ukusikwa ngokulandelelanayo, mhlawumbi ukude ujike inxalenye kunye nomatshini ngezigaba ukulinganisa ukukhululeka koxinzelelo. Olu hlobo lolwazi lwezizwe lugqithiselwa xa zombini iinkqubo ziphantsi kophahla olunye. Ingcali yoomatshini ifunda ukuba kuvakala ntoni na ukuphoswa kakuhle kwisiseko sethu kwaye kuvakala ngathi kumatshini wokusila, kwaye injineli ye-Foundry ifunda ukuba yintoni efunwa ngumachine ukuze kuseto oluzinzileyo.
Ekugqibeleni, ixabiso lenyani ukuphoswa kwentsimbi yesiko iqabane lilele kule mbono iphelele. Ayikokuthengisa icasting okanye inkonzo yomatshini. Imalunga nokunikezela ngecandelo elisebenzayo elihlangabezana nemilinganiselo yakho yokusebenza. Oko kunokuthetha ukukucebisa ukuba utshintshe imathiriyeli ukuze uphucule ukusebenziseka, ucebisa uyilo lokuyila ukuphelisa umsebenzi wesibini obiza imali eninzi, okanye ukubamba imowudi yokungaphumeleli enokwenzeka ngaphambi kokuba isinyithi sigalelwe. Kumdaka, akukho mgca, kwaye kugcwele ukuthobela. Kodwa ukuyilungisa-leyo yimisebenzi yobugcisa.
UQoqosho olungathethwayo lokuPhinda
Okokugqibela, masingafihli malunga neendleko. Iphupha lenqaku lokuqala eligqibeleleyo lilo kanye—liphupha. Kwisiko lokwenyani, iindawo ezintsonkothileyo, kuya kufuneka uqikelele kwaye ulindele ubuncinci ukuphindaphindwa kwenkqubo yeprototype. Owokuqala ubaleka kukufunda. Iqinisekisa uyilo lokungunda, i-gating, ii-cores, iiparamitha zenkqubo. Sisenokwenza ukugalela kuqala, sinqumle amalungu, senze uvavanyo olungonakalisi, kwaye sifumanise ukuba kufuneka sisuse isinyusi okanye sitshintshe i-vent. Oku asikokungakwazi ukwenza umsebenzi; bubunjineli obunoxanduva. Ivenkile ethembisa inxalenye egqibeleleyo ukusuka kwisiqalo esibandayo kumsebenzi onzima mhlawumbi uxoka okanye uceba ukufihla iimpazamo.
Yiyo loo nto ubudlelwane bexesha elide kunye ne-Foundry efana ne-QSY buxabiseke kakhulu. Loo projekthi yokuqala iseka isiseko. I-Foundry ifunda imigangatho yakho, iinqobo zokuhlola, ukunyamezela kwakho impendulo. Ufunda indlela yabo yokunxibelelana, amandla abo, kunye nendlela abazisingatha ngayo iingxaki. Iprojekthi elandelayo ihamba kakuhle. Iprojekthi yesithathu inokuba nesiqingatha sexesha elide kuba kuninzi okusele kuqondwa. Iindleko zokuphindaphinda kokuqala zihlawula izabelo phantsi komgca.
Ngoko, xa ujonge ukuphoswa kwentsimbi yesiko, jonga ngaphaya koluhlu lwezixhobo kunye nezatifikethi ze-ISO. Khangela amabali emva kwabo. Buza malunga nexesha apho babenokusilela okukhulu kunye nendlela abayisombulula ngayo. Impendulo iya kukuxelela ngakumbi malunga nobuchule babo kunayo nayiphi na incwadana. Injongo asikokuba ungabi nangxaki; kukuba ube namava kunye nengqibelelo ukuyilungisa, ufunde kuyo, kwaye ubhake olo lwazi kwithululo elilandelayo. Yiloo nto oyithengayo ngokwenene.
