Uva 'i-wax elahlekileyo iphosa intsimbi engatyiwayo' kwaye abantu abaninzi bafanekisela le nkqubo ingenasiphako, phantse engummangaliso apho ufumana indawo egqibeleleyo engenasilasi ngqo ngaphandle kokungunda. Inyani, ngakumbi ngamabakala afana ne-304 okanye i-316, ininzi kakhulu malunga nokulawula okulindelweyo kunye nokwazi apho inkqubo ikulwa khona. Akukhona nje ukunyibilikisa isinyithi kwaye uyigalele; luthethathethwano kunye nokuziphatha kwezinto, ukusuka kwinqanaba lepatheni ye-wax yonke indlela ukuya kweso sila sokugqibela. Ukukhanya kuza kamva, emva kokusombulula iingxaki ezininzi.
I-alloy ayiloPhepha nje eliKhethekileyo
Ukukhetha ibakala elingenasici yindawo yokuqala yokwenyani, kwaye akusoloko kuthe tye. I-316 iyindlela yokuya kukumelana nokuhlwa, ngokuqinisekileyo, kodwa ukuziphatha kwayo kwahlukile kwi-304. Ithanda kakhulu ukukrazula okushushu ukuba i-gating yakho kunye nokupholisa akubizwanga. Ngamanye amaxesha, kuya kufuneka utyhale umva kwaye ucebise uhlengahlengiso kuyilo okanye uxoxe ukuba i-CF8M (i-cast elingana ne-316) enokwakheka okuhlengahlengisiweyo kancinane ukwenzela ukuphosa okungcono kunokufikelela kwinjongo efanayo yesiphelo. Lulwazi olusebenzayo lwe-alloy olwahlula ukuphosa okusebenzayo kwimfumba ye-scrap.
Ke kukho umba wokugqitywa komphezulu ngqo kwiqokobhe leceramic. Abantu balindele ukuba inkangeleko yakudala engenastain kwangoko emva kokunkqonkqoza. Eyona nto uyifumanayo yimatte kancinane, indawo ehlala inezikali efuna umsebenzi. I ukulahlwa kwewax elahlekileyo inkqubo ngokwendalo ishiya olu lusu luphoswe. Ukuba ilunge kangakanani kuxhomekeke kakhulu kumgangatho we-ceramic slurry kunye nendlela yokukhupha. I-flash dewaxing kwi-autoclave ixhaphakile, kodwa ukuba iiparamitha zicinyiwe, ungafumana iintanda zeqokobhe ezivumela ukuba isinyithi singene, sidala ezo ndawo zirhabaxa, ezidityanisiweyo eziyiphupha elibi lokucinywa kumatshini kamva.
Ukuthetha ngomatshini, kulapho isakhono senkonzo epheleleyo yeqabane siba sibaluleke kakhulu. Inkampani efana I-Qingdao Qiangsenyuan Technology (QSY) iyayiqaqambisa kakuhle le nto. Ayenzi nje loo nto utyalo mali; banamashumi eminyaka kwi-CNC machining kakhulu. Oku kukhulu. Kuba xa ujongana nokujulwa kwentsimbi engatyiwayo, ngakumbi kumacandelo achanekileyo, usoloko ufuna umsebenzi we-CNC wasemva. Ukuba nayo yonke into phantsi kophahla olunye kuthetha ukuba bayaluqonda uxinizelelo lwendalo, iindawo ezinokuba nzima ekubandeni, kwaye banokucwangcisa ulandelelwano lomatshini ngokufanelekileyo. Ithintela umdlalo otyholwa phakathi kweevenkile ezahlukeneyo kunye neevenkile zomatshini.
Apho Inkqubo Iluma ngasemva: Ukugada kunye nokushwabana
Uyilo lokungena kwi-wax elahlekileyo lubugcisa obuninzi kunenzululwazi. Ulwa nokucutheka, okubalulekileyo ngokungenasici. Amasango ayizondlela nje zentsimbi; zizidama zesinyithi esinyibilikisiweyo esondla ukugalela njengoko siqina, kuthintelwa ukushwabana kweporosity. Ukuba zincinci kakhulu okanye zibekwe ngokungalunganga, uya kufumana i-porosity kumacandelo ashinyeneyo. Inkulu kakhulu, kwaye udala iisinki zobushushu ezinkulu ezigqwetha indawo okanye zidale imingxunya ecuthekileyo kwisango ngokwalo, elinokuthi lihambe liye kuphosa.
Ndikhumbula ibhetshi yemizimba yevalvu kwiminyaka embalwa edlulileyo. Ijometri yayintsonkothile, ineflange enzima kwelinye icala. Umthi wokuqala wepateni esawakhayo wawunesango eliphezulu elikumgangatho ophezulu. Isiphumo? I-shrinkage porosity kanye kubuso obunyukayo be-flange. Kwafuneka sibuyele umva, siwuyila ngokutsha lo mthi ukuze sisebenzise amasango anzima, abekwe ngobuchule asebenza njengezondla, size sitshintshele kwisixokelelwano sesango elisezantsi ukuze kugcwaliswe ngokuzolileyo. Yongeza iindleko kwipatheni, kodwa yayikuphela kwendlela yokufumana ukuphoswa kwesandi. Olu luhlobo lokuphindaphinda, i-tweak eqhutywa ngamava ongayi kuyifumana kwincwadi yesifundo.
Olunye ubuqili liqokobhe le-ceramic ngokwayo. Ukufumana i-stainless, uhlala ufuna i-slurry ephambili kunye nomgubo ocolekileyo kakhulu we-zircon ukuze ufumane indawo egudileyo egqiba ukucoca. Kodwa iidyasi zogcino zifuna amandla kuba i-stainless inzima kwaye igalela kubushushu obuphezulu. Oko kuthuswa kwe-thermal xa i-1500 ° C + yentsimbi ibetha iqokobhe ikhohlakele. Iqokobhe elibhityileyo kakhulu okanye elingatshiyo ngokupheleleyo liya kuqhekeka. Iqokobhe elishinyene kakhulu lisenokungaphumi kakuhle, nto leyo ekhokelela kumgibe werhasi. Ibhalansi, kwaye ngamanye amaxesha ufumana kuphela iresiphi echanekileyo yokwakheka kwenxalenye ethile ngokugalela uvavanyo okanye ezimbini.
I-Post-Casting: Amanyathelo Okwenza okanye Okwaphulwa
I-Knockout kunye nokunqunyulwa kulapho ubamba khona umoya wakho. Ubona ukuphosa okukrwada, kusancanyathiselwe kwinkqubo yayo yesango. Nge-stainless, awukwazi ukuyibetha nje ngehamile; usengozini yokuqhekeka okubandayo. Iindlela zokushisa ezifana ne-plasma okanye ukusika kwe-abrasive zisemgangathweni, kodwa kufuneka uqaphele ukuba ungadlulisi ubushushu obuninzi kumzimba wokuphosa, onokuchaphazela i-metallurgy kwindawo echaphazelekayo kubushushu, ngakumbi ukuba ibakala elizinzile.
Unyango lobushushu luhlala lungakhethi. Kuninzi lwe-austenitic stainless castings, udinga unyango lwe-annealing yesisombululo-ukufudumala ukuya ku-°C kwaye emva koko ucime ngokukhawuleza. Oku kunyibilikisa nayiphi na i-chromium carbides ekusenokwenzeka ukuba iye yawa kwimida yengqolowa ngexesha lokupholisa, ethi ukuba ayiphathwanga, ibangele uvakalelo kwaye ikhokelele kukusilela kokuhlwa. Kodwa ukucima ngokukhawuleza kwi-complex, i-cast-wall-casting casting? Eso sisimemo sokugqwethwa. Ukulungiswa ngexesha lokunyanga ukushisa kubaluleke kakhulu njengomjikelezo ngokwawo. Ivenkile eyiqondayo le nto, njenge-QSY ngokudibeneyo CNC Machining kunye nendlela yokuphosa, inokuyila inxalenye kunye nenkqubo ukulungiselela okanye ukulungisa le ntshukumo ilindelekileyo.
Ekugqibeleni, ukuhlolwa kunye nokugqiba. Uvavanyo lokungena kwidayi ngumhlobo wakho osenyongweni wokufumana iziphene ezingaphezulu. Ukuze ungabinastainless, kufuneka usebenzise i-clorine-free penetrant ukunqanda ukuthotywa kwe-corrosion. Ukusila nokupholisha ngumsebenzi onzima. Uqala ngegrit erhabaxa ukususa izibonda zesango kunye nokungafezeki komphezulu, kodwa kufuneka ulumke. Nakuphi na ukutshiseka kokusila okanye intsimbi efakwe kwivili elingcolisekileyo inokugqwala kamva, ize yonakalise ukuxhathisa komhlwa. Yinkqubo ejolise kwiinkcukacha, ecothayo ukuba i-automation isasokola nayo kwiijiyometri ezintsonkothileyo.
Ukudityaniswa noMatshini: Ukuhamba komsebenzi okwenyani kwehlabathi
Kulapho isithembiso se ilahleko yewax iphosa intsimbi engatyiwayo yenzeka ngokwenene. Ubunakho obusondeleyo bobume bomnatha buyamangalisa ekunciphiseni inkunkuma yomatshini kwiialloyi ezibizayo. Kodwa i-close-net-shape ayiyomilo yenetha. Uhlala ushiya isitokhwe somatshini. Kagakanani? Lubizo lomgwebo olo. Incinci kakhulu, kunye nokutshintsha okuncinci kokuphosa okanye isiphene somphezulu kuthetha ukuba inxalenye ingaphantsi. Kakhulu, kwaye uchitha ixesha lobuchwephesha kunye nobomi besixhobo kwizinto ezinzima ezingenasici.
I-Foundry elungileyo iya kusebenza kunye ne-machinist kwasekuqaleni. Baza kuxoxa ngamanqaku edatha yokwenza oomatshini. Rhoqo, uya kuyila iipads ezithile okanye iimpawu kwi-casting ezingabalulekanga kodwa zibonelele ngomphezulu ococekileyo, othembekileyo ukuze umatshini we-CNC awubambe kwaye ubhekisele kuwo. Le ntsebenziswano ibalulekile. Ukujonga imodeli ye-QSY, apho baphatha khona zombini ukuphosa kunye nomatshini, le ngxelo yempendulo ingaphakathi kwaye ingoko nangoko. Iqela lomatshini lixelela iqela elidlalayo ukuba lihlala lifumana indawo enzima kwindawo ethile, enokuthi ibonise umba wokupholisa, kwaye inkqubo ingalungiselelwa ukubaleka okulandelayo.
Sakhe sazama ukukhupha oomatshini bokwenza ezinye izindlu zempompo kwivenkile yoomatshini abenzi bamayeza enziwe afana nalawo aveliswe ngabenzi. I-castings yayilungile, kodwa oomatshini babaphatha njengeebhiliti. Bathatha amanxeba anzulu, amanxeba abukhali, bavuthela izixhobo kwiindawo ezinzima ezingalindelekanga (ukugodola okuncinci kubumba), emva koko batyhola ukubunjwa kwethu ngokungaguquguquki. Xa usebenza nomboneleli odibeneyo othe nkqo, loo ngxaki iyanyamalala. Bafunda ingxelo yokuphosa, bayayazi imeko ye-as-cast, kwaye bacwangcisa iindlela ze-CNC ukuze basebenze nayo, kungekhona ngokuchasene nayo.
Iingcamango Zokuqukumbela: Yinkqubo, Hayi iQhosha
Ekupheleni kosuku, impumelelo ukulahlwa kwewax elahlekileyo kwintsimbi engenastainless imalunga nokuhlonipha lonke ikhonkco. Asiyonkonzo yorhwebo. Ukukhetha i-alloy, ipateni kunye noyilo lwesango, ukwakha iqokobhe, ukugalela, unyango lobushushu, kunye nomatshini wokugqibela zizigaba ezidityanisiweyo apho izinto zinokuhamba kakubi. Ixabiso livela ekubeni nomboneleli ongaziboni nje njengesiseko, kodwa njengomboneleli wesisombululo sokuvelisa.
Yiyo loo nto imisebenzi enembali ende, njengeminyaka engama-30+ ekhankanywe ngu Qingdao Qiangsenyuan Technology, idla ngokunikezela ngokuthembekileyo ngakumbi. Kusenokwenzeka ukuba babone uninzi lweendlela zokusilela. Baphose yonke into ukusuka kwizibiyeli ezilula ukuya kwi-impellers ezinzima kuyo yonke into ukusuka kwinqanaba intsimbi engenasici kwezo ngxubevange zisekwe nickel ngobuqhophololo. Loo nkumbulo yeziko iguqulela ngokuthe ngqo kwizinto ezothusayo ezimbalwa kumgangatho wevenkile.
I-takeway? Musa ukuthenga nje ngexabiso ngekhilogram nganye kwi-casting. Jonga ixabiso lilonke lenxalenye egqityiweyo, eyenziwe ngoomatshini neyahlolwayo. Kwaye okubaluleke ngakumbi, khangela ubungqina bezandla, ukuxazulula iingxaki ezisebenzayo kwindlela yabo. Buza malunga nezicwangciso zabo zokungena eziqhelekileyo zenxalenye efana neyakho, indlela abaphatha ngayo ukugqwethwa konyango lobushushu, okanye baseka njani iidatum zomatshini. Iimpendulo ziya kukuxelela ukuba ujongene nengcali yokwenyani okanye umntu ophakathi.
