Xa abantu abaninzi besiva iinxalenye zentsimbi ezingekho mgangathweni, bafanekisela isibiyeli esilula kunesiqhelo, okanye igiya enamanani amazinyo angaqhelekanga. Leyo yimbono yokuqala ephosakeleyo. Enyanisweni, lihlabathi elichazwa ngokungabikho kwenombolo yekhathalogu. Ayisiyonto nje malunga nemilinganiselo elungisiweyo; imalunga nokwenza isisombululo esisebenzayo apho icandelo elingekho kwishelufu lisilela, kaninzi phantsi kweemeko ezohlwayayo zobushushu, uxinzelelo, okanye umhlwa. Olona celomngeni lokwenene asikokwenza nje oko—kukwenza ukuba isebenze ngokuthembekileyo xa kungekho mzekelo unokulandelwa.
Undoqo we-Non-Standard: Yinkqubo, hayi iMveliso
Awukwazi ukwahlula ezi nxalenye kwikhonkco lenkqubo. Umzobo uhlala kwidesika yakho-uhlala usiba ngumzobo orhabaxa ovela kwinjineli-kwaye umbuzo wokuqala awunakukwazi umatshini lo? Yenzelwe ntoni? Umsebenzi uyalela yonke into: imathiriyeli, indlela yokuphosa, ukunyamezelwa komatshini. Umzekelo, icandelo levalvu yobushushu obuphezulu kwisityalo sekhemikhali asiyonxalenye yentsimbi engenasici. Iqala njengokuphoswa kotyalo-mali kwi-alloy esekwe kwi-nickel ukusingatha ukubola, emva koko iqhube i-CNC echanekileyo yomatshini wokutywina, ilandelwa lunyango olukhethekileyo lobushushu. Inxalenye izalwa kolu landelelwano. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), kunye neminyaka engamashumi amathathu beqokelela amava kuzo zombini izinto zokusa kunye nokwenza oomatshini phantsi kophahla olunye, bafumana oku ngaphakathi. Ungayibona indlela yabo kwi-portal yabo ku-https://www.tsingtaocnc.com—abanikezeli ngeenkonzo kuphela; babonisa isakhono esidibeneyo. Eso sitshixo. Ukufama ngokusasaza kwivenkile enye kunye nokwenza umatshini ukuya kwenye ngenxalenye yokwenyani engeyiyo eyomgangatho yiresiphi yokukhomba umnwe xa kukho into engahambi kakuhle.
Ukukhethwa kwezinto eziphathekayo kulapho izigqibo zokuqala eziphambili zenzeka khona, kwaye apho iimpazamo zibiza kakhulu. Umxhasi wake wanyanzelisa kwi-316 engenastainless ngenxalenye kwindawo eneklorini eninzi, ecaphula umgangatho woshishino. Sityhale ngasemva, sicebisa i-duplex engenastainless okanye ialloy yenickel. Bahamba ne-316 ukugcina iindleko. Kwiinyanga ezintandathu kamva, sasisenza iseti yokutshintsha ngealloyi engama-20. I-non-standard isoloko ithetha ukuba indawo yokusebenza ayinamgangatho nayo. Iilayibrari eziphathekayo ozibonayo kwindawo efana ne-QSY's, idwelisa yonke into ukusuka kwintsimbi etyhidiweyo ukuya kwi-alloys esekwe kwi-cobalt, ayikho nje imenyu; zizixhobo zokusombulula ezi ngxaki zingathethwayo zokusingqongileyo.
Isigaba seprototyping sikhohlakele. Kulapho uyilo lwethiyori ludibana nenyani ebonakalayo. Unokuba nemodeli entle ye-CAD yendlu entsonkothileyo, enodonga olucekeceke lwe turbine e-Inconel. Kodwa ngaba inkqubo yokubumba iqokobhe ingafikelela kobo bukhulu bodonga ngaphandle kweziphene? Ngaba isixhobo se-CNC sinokufikelela kumajelo angaphakathi ngaphandle kokuphambuka? Sibe noyilo olubonakala lugqibelele kodwa lufuna ukuba siphuhlise izilungiso zesiko ukuze nje sibambe icwecwe ngexesha lomatshini, songeza i-30% kuluhlu lwexesha. Le yindleko efihliweyo yomsebenzi ongekho umgangatho. Asikokungaphumeleli; yirhafu yeR&D.
Xa ukuphosa kunye noMatshini kungqubana (Ngokoqobo)
Le yeyona nkcukacha yegritty eyona gloss ngaphezulu: i-handoff esuka kwi-Foundry ukuya kwivenkile yomatshini. Kwinxalenye eqhelekileyo, une-spec. Kwinxalenye engeyiyo eyomgangatho, useka i-spec ngenqaku lokuqala. Ukubunjwa kweqokobhe lokungunda, ekwaziwa ngokugqitywa kwayo kakuhle kunye nokuchaneka komgangatho, kusenezinto eziguquguqukayo-amazinga okuncipha ahluka kancinci kwibhetshi, ngakumbi ngeealloyi ezikhethekileyo. Ingcali yoomatshini kufuneka yazi ukuba iphi i-datum ekujuleni ekrwada. Ngaba ngumphezulu? Umngxuma wokulinga? Oku sikufunde kabuhlungu kwangethuba ngokwenza oomatshini ukusuka kumbindi wethiyori kwindawo yempompo. Isiphumo yaba yinxalenye yomatshini entle enobungqingqwa bendonga obuguquguquka nge-1.5mm, buyenza ingabi namsebenzi. Ngoku, inkqubo ibandakanya uhlolo loyilo lwangaphambili kwindlela yokuphosa yokuqala, ukuyipeyinta ngokoqobo ngedayi eluhlaza kunye nokubhala ezona nkcukacha zomatshini kuzo. Bubuchwephesha obuphantsi kodwa bubalulekile.
CNC machining castings non-standard lelinye irhamncwa. Awuqali ngebhilethi efanayo. Ubambelela kwinto erhabaxa, ehlala ingalingani, ukuphosa. Ukusikwa kokuqala kubaluleke kakhulu-kuseka inqwelomoya yakho kwaye ihlala ityhila i-porosity engaphantsi komhlaba okanye ukubandakanywa. Ndikhumbula intsimbi yentsimbi enkulu engenanto apho isixhobo sasincokola kwipasi yokuqala. Sifumene indawo enzima, indawo epholileyo ukusuka kwinkqubo yokuphosa. Ulandelelwano lonke lomatshini kwafuneka luhlengahlengiswe kwimpukane, ukutya okucothayo kunye nesantya. Ukuba uyivenkile yomatshini ethenga izinto ezisasazwayo ekrwada kwiqela lesithathu, oku kufunyenweyo kukhokelela ekumisweni nasekutyholweni. Xa i-Foundry kunye nevenkile yomatshini idityanisiwe, njenge-QSY, impendulo ikhawuleza. Iqela Foundry unako ukunyenyisa iqondo lobushushu ukugalelwa okanye ngundo ukutyabeka kwibhetshi elandelayo, kunye neqela machining uhlengahlengiso inkqubo yabo. Ijika ingxaki ibe yinkqubo yokuphucula.
Ke kukho ijometri enika abadwelisi benkqubo iintloko. Iipokotho zangaphakathi ezinzulu, ukunqunyulwa kwe-investment-cast blades turbine blades, ii-angles ezidityanisiweyo ezingaqhelekanga. Ayikokukwazi nje kwe-5-axis; imalunga necebo lendlela yesixhobo. Ukusebenzisa isixhobo eside kakhulu kunokubangela ukuphambuka, ukonakalisa ukunyamezelana. Ngamanye amaxesha, kuya kufuneka uyile kwaye wenze isibambisisixhobo esingesiso esiqhelekileyo okanye ibha yesiko edinayo. Injongo asikokususa isinyithi kuphela; kukwenza oko ngaphandle kokwenza uxinzelelo okanye ukungcangcazela okunokuchaphazela ukusebenza kwenxalenye yokugqibela. Kulapho iminyaka engama-30 yemvelaphi ye-QSY ikhankanya ayingomgca wokuthengisa-lithala leencwadi lezisombululo ezidlulileyo ukutsala ukusuka xa kufika umngeni omtsha, ongaqhelekanga.
I-Alloy Dilemma: Iindlela eziKhethekileyo ezixabisa kakhulu, kodwa ziyimfuneko
Abathengi bayabhaqa kwisicatshulwa se-cobalt-based alloy part. Ndiyayifumana. Iindleko zezinto eziphathekayo ngekhilogram ziyamangalisa. Ukuthetheleleka akukho kwimathiriyeli ngokwayo, kodwa ekusileleni kuyakuthintela. Sasebenza kwicandelo leplastiki ye-extrusion die-ipleyiti yokunxiba. Isixhobo esiqhelekileyo sensimbi siya kuhlala malunga neenyanga ezi-3 kwi-abrasive, i-polymer flow flow hot. Siyiprototype kwi-cobalt-chromium alloy (uhlobo lweStellite). Ubuchwephesha yayiliphupha elibi; iyasebenza-yenza lukhuni ngoko nangoko, ifuna ukusetwa okuqinileyo kunye nezixhobo ezibukhali, ezikhethekileyo ze-carbide. Kodwa eso siqwenga sahlala ngaphezu kweenyanga ezili-18. Ugcino lwexesha lokuphumla lunciphise ixabiso lenxalenye. Ubuchwephesha apha bumbini: ukwazi ixesha lokucebisa ezi alloys ezikhethekileyo, kunye nokwazi indlela yokusebenza nazo. Ayingobuchule obuthengayo nje; uyakha ngokusebenzisa izixhobo ezonakeleyo kunye neetephu ezaphukileyo.
Unyango lobushushu kwezi non-standard alloys post-machining yenye indawo mgodini. Kwiintsimbi ezininzi eziphezulu zokusebenza kunye ne-nickel alloys, unyango lobushushu luyimfuneko ekufezekiseni izinto eziphathekayo ezifunekayo-ubunzima, amandla okuqina, ukukhululeka koxinzelelo. Kodwa unyango lobushushu lunokubangela ukuphazamiseka. Ulandelelwano lubaluleke kakhulu. Ngaba unomatshini orhabaxa, ukuphatha ubushushu, emva koko ugqibe umatshini? Okanye ngaba umatshini ngokupheleleyo, emva koko ukuphatha ubushushu kwiqondo lobushushu elisezantsi ukunciphisa warping? Akukho mpendulo yencwadi. Kuxhomekeke kwijometri yenxalenye, ukuziphatha kwe-alloy, kunye nokunyamezela kokugqibela. Kuye kwafuneka ukuba silahle iibhetshi kuba sifumene ulandelelwano olungalunganga kwimilo yenxalenye entsha, nangona besikhe sasebenzisa ialloyi enye ngaphambili. Ijiyometri entsha nganye ilinge elitsha.
Unxibelelwano: Esona sixhobo sibaluleke kakhulu esingengoMgangatho
Olona ntsilelo lukhulu alufane lube kukungakwazi kobugcisa. Zivela kwizithuba zonxibelelwano. Injineli iyila umsebenzi. I-Foundry icinga malunga ne-castability. I-machinist icinga malunga nokufikelela kwesixhobo kunye nokunyamezela. Xa ezi zingamaqumrhu ahlukeneyo, ufumana umdlalo womnxeba. Umzobo uyatolikwa, emva koko utolikwe kwakhona. Inqaku elibalulekileyo malunga nokugqitywa komphezulu wokutywina (yithi, i-0.8μm Ra) inokulahleka ukuba umzobo uyibiza kuphela kumanqaku aqhelekileyo kwaye hayi kwifowuni ethile. Ngoku sinyanzelisa umnxeba wokukhaba ngawo nawuphi na umsebenzi ontsonkothileyo ongengowomgangatho, kunye nenjineli yomxhasi, isiseko sethu esikhokelayo, kunye nesikhokelo sethu somatshini konke kumgca. Siwela umgca wokuzoba ngomgca, sibuza yonke into. Ngaba le radiyasi kufuneka ibe yi-3mm, okanye yeyokucocwa nje? Ngaba singafaka isixhobo esincinci sokufikelela kwi-chamfer apha? Le ncoko ixabiseke ngaphezu kwayo nayiphi na isoftware ephambili.
Yiloo nto imbali yokusebenza kwenkampani ibalulekile. Xa ubona ukuba inkampani efana QSY ibikwisakhelo kunye nobuchwephesha ngaphezulu kweminyaka engama-30, oko kuthetha ukuba bahlelele ukuhamba komsebenzi wabo ukuququzelela olu hlobo luchanekileyo lwencoko yababini yoqeqesho. Ibhakiwe kumsebenzi wabo. Iwebhusayithi yabo, https://www.tsingtaocnc.com, ibeka iinkonzo zabo malunga nomnikelo odibeneyo-igobolondo lokungunda kunye nokutyalwa kotyalo-mali kumatshini we-CNC. Olo lwakhiwo aluzenzekelanga; yimpendulo kwimfuno esisiseko kwi iindawo zentsimbi ezingezizo eziqhelekileyo ihlabathi: ukuhlanganiswa okungenamthungo ukusuka kwintsimbi etyhidiweyo ukuya kwinxalenye egqityiweyo.
Uxwebhu luyintsika yokugqibela, engathandekiyo. Ngenxalenye eqhelekileyo, uyithumela ngesatifikethi sokuthotyelwa. Kwinxalenye engeyiyo eyomgangatho, uhlala ufuna i-dossier epheleleyo: ii-certs zezinto eziphathekayo, iitshathi zokunyanga ukushisa, iingxelo zokuhlola inqaku lokuqala kunye nedatha ye-CMM, kunye neefoto zezigaba ezibalulekileyo. Oku asikobugqeba; kukulandeleka. Xa loo nxalenye ingcwatywa kwindibano yezigidi zeedola kwiminyaka emibini ukusuka ngoku kwaye kuphakama umbuzo, loo dossier kuphela kokhuselo. Ukwakha oku kwinkqubo yokuhamba ukusuka kusuku lokuqala luphawu lomthengisi oqolileyo.
Ekugqibeleni, Imalunga nokuSombulula Ingxaki Engabhalwanga
Ngoko, sithetha ngantoni ngokwenene kunye neengxenye zetsimbi ezingekho mgangathweni? Asivelisi nje into. Senza isisombululo kwingxaki engekasonjululwa ngaphambili ngendlela efanayo. Ixabiso alikho kwikhilogram yentsimbi ethunyelwe ngenqanawa. Kulwazi olufakiweyo-ukuqonda indlela i-alloy esekelwe kwi-nickel ehamba ngayo kwi-investment mold, i-intuition yendawo yokubeka indawo yokunyuka ukukhusela i-shrinkage kwi-casting steel casting, amava okukhetha i-coating efanelekileyo kwisixhobo se-carbide sokugaya i-cobalt alloy.
Yintsimi eqhutywa ngokwahlukileyo, hayi imithetho. Inxalenye entsha nganye yiprojekthi encinci, enemingcipheko yayo kunye nejika lokufunda. Iinkampani ezihlala zihlala, ezo zakha i-30-year-deputation efana ne-QSY, zenza njalo ngokucwangcisa indlela abasingatha ngayo ezi zinto zangaphandle-kungekhona ngokuzenza umgangatho, kodwa ngokuba nenkqubo eqinile, yokunxibelelana, kunye nedibeneyo enokuthi ithathe ukuguquguquka kwaye ihambise inxalenye esebenzayo. Ngexesha elizayo xa ubona i-RFQ engeyiyo eyomgangatho, jonga ngaphaya komzobo. Jonga ukuba umthengisi ubuza malunga nomsebenzi, indawo engqongileyo, indlela yokungaphumeleli kwenxalenye yangaphambili. Loo nto ibonisa ukuba bakwishishini lokusombulula iingxaki, kungekhona nje ukusika isinyithi.
