Ukuba ucinga ukuba ukubunjwa komxhuzulane kumalunga nokuvumela umxhuzulane ukuba wenze umsebenzi, uyawuphosa umsebenzi wobugcisa. Lulawulo oluchuliweyo, ukuthambeka okuphantse kungabonakali kweleyile, ukuthambeka kobushushu obuvayo esidleleni sakho kufutshane nomngundo—kulapho eyona nkqubo iphila khona. Uninzi lwamaphepha eenkcazo kunye neengcaphuno ezikhawulezayo ziyithatha njengokhetho olulula, olusezantsi, kodwa oko kukubiza kakubi. Umahluko phakathi kokuphoswa kwesandi kunye nemfumba ye-scrap ihlala ixhomekeke kwiinkcukacha akukho fayile ye-CAD ibonisa.
IFiziksi engaqondakaliyo yokugalela okulula
Makhe sicacise. Ixesha ukuphosa ngundo womxhuzulane kuthetha amandla okwenziwa, kodwa xa usebenza, ulawula ngokusebenzayo ukuwa okulawulwayo. Intsimbi ayiwi nje; iyaqukuqela. Ukuphazamiseka kakhulu, kwaye ufumana i-air entrapment kunye neefilimu ze-oxide-iziphene ezinokuthi zingabonakali de kube yi-machining, indlela ekhohlakeleyo yokufumanisa ukuba uchithe iveki. Ndifunde oku kwangethuba ngebhetshi yezindlu zempompo. Ijiyometri yayinecandelo elicekethekileyo elondla kwindawo etyebileyo. Sagalela ngqo, isimbo sencwadi. Isiphumo? I-shrinkage porosity kanye kwindawo yokuhlangana. Ukutya komxhuzulane bekunganelanga; besidinga umngundo ngokwawo ukunceda ukwalathisa ukuqina.
Kulapho uyilo lokungunda-isango lokungena kunye nokunyuka-luba bubugcisa obaziswa ngokuqiniswa kokulinganisa kwaye, ngokungafihlisiyo, uvavanyo kunye nempazamo. Awuyenzi nje i-negative yenxalenye; uyila inkqubo yobushushu yethutyana. Abantu ku Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) fumana oku. Ngemvelaphi yabo yeminyaka engama-30, babonile ukuba inkqubo eyilwe kakuhle yomxhuzulane egalelwe isanti okanye ukungunda okubotshwe yintlaka inokuvelisa ingxinano kunye neempawu zomatshini ezikhuphisana neenkqubo ezibiza kakhulu kwiintsapho ezithile. Imalunga nokubopha ukuhamba kwendalo, hayi ukulwa nako.
Ukukhethwa kwezinto eziphathekayo ngomnye umaleko. Sithetha iintsimbi eziphonsiweyo, ezinye iintsimbi, kwaye ngakumbi, ezo zinto zisebenza kakhulu. Ukugalela i-alloy esekelwe kwi-nickel phantsi komxhuzulane sisilo esahlukileyo kunentsimbi engwevu. Ubushushu bukhulu ngakumbi, utshintsho lwe-fluidity, kunye ne-mold material reaction yinkxalabo yokwenene. Awukwazi ukusebenzisa iresiphi yebhiskithi efanayo kwisidlo ngasinye.
Apho Ikhazimula khona (Kwaye apho Ingakhanyisiyo)
Ngoko uyikhetha nini? Kwiindawo eziphakathi ukuya kwezinkulu ezinobungqingqwa obufanayo bodonga, ikholisa ukuba yeyona ndlela inexabiso eliphezulu yokwenza isinyithi phaya. Cinga iziseko zoomatshini, izikhewu ezinkulu zegiya, okanye amacandelo olwakhiwo lwezixhobo ezinzima. Iindleko zezixhobo zokubumba zisezantsi kunoxinzelelo oluphezulu lokuphosa ukufa, kwaye unokufezekisa iijiyometri zangaphakathi ezintsonkothileyo ezinobumba besanti.
Kodwa nanku umqobo osebenzayo: ii-engile zokuyila. Ngenxa yokuba awuyitofu isinyithi phantsi koxinzelelo oluphezulu, udinga idrafti enesisa ngakumbi yokususwa kwepateni. Ndikhe ndanabaqulunqi bathumela ngaphaya kwamalungu aneendonga ezikufutshane-ezithe nkqo, ezilungiselelwe ukwenziwa ngomatshini, kwaye emva koko balk kwidrafti ye-3-degree ecetyisiweyo. Kufuneka uchaze ukuba ukhetho lwe ukuphosa ngundo womxhuzulane imisela inkululeko ethile kunye nemiqobo yoyilo. Luthethathethwano phakathi kweyona milo ifanelekileyo kunye nenyani ebonakalayo yokutsala ipateni kwisanti exineneyo.
Ukugqitywa komphezulu yenye into exelayo. I-gravity yesanti yokuphosa iya kuba neempawu ze-gritty texture, i-imprint ngqo yengqolowa yesanti. Ayisiso isiphako; ngutyikityo. Ukuba ufuna isipili esifana ne-cast-cast surface, ujonge iinkqubo ezifana nokuphosa utyalo-mali okanye ukubumba iqokobhe-ekuthi, kungekhona nje, ezinye izinto ezikhethekileyo kwivenkile efana ne-QSY. Baza kuba ngabokuqala ukukuxelela ukuba ukukhetha inkqubo ngumthi wezigqibo, ukuqala ngomsebenzi wenxalenye kunye nokuphela kwexabiso lilonke.
Ukuxhawula ngesandla ngoMachining
Oku kubalulekile: akukho nxalenye yokuphosa umxhuzulane sisiqithi. Iphantse yahlala isiya kumatshini. Yiyo loo nto ubudlelwane phakathi kwe-Foundry kunye nevenkile yomatshini busondelene kakhulu. Utshintsho olungundoqo olubekwe ngendlela engeyiyo ngeemilimitha ezimbalwa lusenokungabonakali ekujuleni ekrwada kodwa luya kubangela ukuba iziko lomatshini likhale, liqhekeze izixhobo njengoko lizama ukubetha imilinganiselo ethile eludongeni olubhitye kakhulu ngoku.
Simisele umthetho olula kodwa osebenzayo: kwiimpawu ezibalulekileyo, siyakushiya isitokhwe esongezelelweyo kumzobo wokuphosa, kodwa sinokuthumela inqaku lokuqala lokuphosa kwi-CMM kunye noyilo lomatshini womatshini. Oku kuvumele abadwelisi benkqubo be-CNC kwinqanaba lomatshini-nokuba kungaphakathi okanye kwiqabane elifana ne-QSY owenza zombini ukuphosa kunye. CNC Machining-ukubona eyona ndawo yogcino lwedatha kwaye uhlengahlengise amanqaku azo anoziro ngokufanelekileyo. Ijike inkunkuma enokubakho yaziindawo ezisebenzisekayo. Ukudibanisa ukuphosa kunye nomatshini phantsi kophahla olulodwa, njengoko kunjalo, kuphelisa umsantsa omkhulu wonxibelelwano. Oomatshini banokuthetha ngokuthe ngqo kwi-foundry guys malunga nendawo enzima okanye i-void engalindelekanga.
Izinto ze-QSY ziluhlu, njenge-cobalt-based alloys, ngumzekelo ogqibeleleyo. Ukuziphosa ngomnye umngeni; ukuwenza ngomnye umyalelo wobunzima. Ukuba nenkqubo yonke yetsheyini elawulwa liqela elinye elinolwazi oluqokelelweyo kuthetha ukuba i-Foundry inokuhlengahlengisa unyango lobushushu kancinci ngokusekelwe kwingxelo evela kumgangatho womatshini malunga nokunxitywa kwesixhobo, ukwenza iluphu yengxelo enesidima ongayifumaniyo nababoneleli abadityanisiweyo.
I-Reality-World Compromise: Ibali leBracket
Ndikhumbula isibiyeli sesixhobo se-offshore. Ushicilelo lufuna ialloyi yentsimbi engatyiwayo, imithwalo ephucukileyo yolwakhiwo, kunye nemingxunya emininzi ebhorekileyo enokunyamezelana okuqinileyo. Ingcinga yokuqala yayilutyalo-mali oluchanekileyo. Kodwa loo nxalenye yayilingana nesutikheyisi—utyalo-mali lwaloo mthamo wesinyithi ngewawubiza imali eninzi kakhulu.
Sicebise ngomxube: ukuphosa ngundo womxhuzulane kwimilo engundoqo yomzimba, kusetyenziswa ukungunda kwesanti ebotshelelwe ngokwekhemikhali ukulungiselela uzinzo olungcono lwedimensional kunesanti eluhlaza, kwaye emva koko kugalelwe izifakelo zentsimbi ezichanekileyo ezibekwe kwindawo ezibalulekileyo zemingxuma. Oku kufakelwe kuya kuba yinxalenye yokusaswa. Ngexesha lomatshini, uya kugrumba kwintsimbi yokufaka, hayi i-cast stainless, eqinisekisa ukunyamezelana. Yayiyinto engaqhelekanga, kodwa yasebenza. Inkqubo yomxhuzulane yasinika ubunzima kunye nokumila kwezoqoqosho, kwaye izifakelo ezifakwe ngaphakathi zasombulula ingxaki echanekileyo. Olu luhlobo lwepragmatic, ukucinga kwenkqubo enqamlezayo echaza ukwenziwa kwehlabathi lokwenyani.
Indlela yokusilela? Ukugalela kuqala. Asizange sizifudumeze ngokwaneleyo ii-insert zentsimbi. Isinyithi esinyibilikisiweyo esibetha intsimbi ebandayo senza indawo epholileyo yasekhaya enqabileyo. Iphumelele uvavanyo olubonakalayo kodwa aluphumelelanga uvavanyo lwe-ultrasonic. Isifundo: yonke into oyifake kwisixokelelwano, nokuba asiyonxalenye yepateni, iba yinxalenye ye-thermal system. Siyicombulula ngokubeka izinto ezifakwe kwi-oven ngaphambi kokuhlanganiswa kwe-mold. Ukulungiswa okulula, kodwa ufunda kuphela ngokwenza, okanye ngokusilela kube kanye.
Ngaphaya kokuThululwa: Iiguquguquko ezingabonakaliyo
Okokugqibela, makhe sithethe ngento enqabileyo kwi-spec: into yomntu. Ubuchule bomthululi ngumgca wokugqibela wokukhusela. Ujonge ifom yesikhumba sesinyithi esangweni, egweba izinga lokuzaliswa ngoxinzelelo lwangasemva aluva nge-ladle. Ngaba ukungunda ukusela isinyithi ngokutyibilikayo, okanye kuyaginya kwaye kunokwenzeka ukubamba umoya? Oku asiyonto izenzekelayo; ngamava. Kumsebenzi ogxile emgangathweni, lo mntu uxabiseke njengenjineli eyile inkqubo yokungena.
Emva koko kukho ukulinda emva kokuphoswa. Uyishiya ixesha elingakanani kubumba? Yiqhawule kwangoko, kwaye ubeka umngcipheko wokugqwetheka okanye ukuqhekeka ngenxa yokupholisa okungalinganiyo. Lindela ixesha elide, kwaye ubulala ixesha lakho lomjikelo wemveliso. Kwisakhelo sentsimbi entsonkothileyo, sinokuyiyeka iphole kubungu ubusuku bonke. Kwiqhekeza lentsimbi elilula, iiyure ezimbalwa. Kukho umgaqo wesithupha, kodwa uhlala uqinisekisa ngokujonga ubushushu kwiziko le-thermal ngeprobe.
Ekugqibeleni, ukuphosa ngundo womxhuzulane bubungqina bokusebenza nefiziksi, hayi ngokuchasene nayo. Kuvakala kusisiseko kuba kunjalo. Ifuna intlonipho kulo lonke ikhonkco: isayensi yezinto eziphathekayo, ubunjineli bokubumba, ulawulo lwe-thermal, kunye nokubulawa kwezakhono. Ayisiyompendulo kuyo yonke ingxaki yokuphosa, kodwa xa inxalenye yejometri, umthamo, kunye nezinto eziphathekayo zihambelana namandla ayo, ihlala iyindibaniselwano engenakulinganiswa yokuthembeka, umgangatho, kunye neendleko-i-workhorse yokwenyani yoshishino. Iivenkile eziye zahlala amashumi eminyaka, njenge-QSY, ziqonda le bhalansi emathanjeni abo, kungekhona nje iincwadana zabo.
