Uma uzwa 'ukutshalwa kwezimali kwemishini yobunjiniyela,' isithombe esiseduze singase sibe ama- blade acwebile, ama-turbine ayinkimbinkimbi e-aerospace. Lokho kuwukuhlangana okuvamile, okucishe kufane. Kodwa emhlabeni ongcolile ongaphansi-kwezinzipho we-earthmovers, ama-excavators, nama-gearboxes anesisindo esinzima, uhlelo lokusebenza luyi-grittier, ukubekezelelana kuxoxisana ngokuhlukile, futhi ukucindezela kwezindleko akupheli. Akukhona mayelana nokuzuza ukuphelela kwethiyori; imayelana nokuletha ingxenye esinda umthwalo wamathani angama-20 emgodini wodaka amahora angu-10,000 ngaphandle kokwehluleka. Lowo mehluko uyikho konke.
I-Alure Engafanele Yenkimbinkimbi
Amaklayenti ngokuvamile afika elungisiwe ku-geometry. Bheka lesi siteshi sangaphakathi, bathi, sikhomba imodeli ye-CAD. Futhi yebo, ukutshala izimali kudlula lokho. Kodwa ngokuxhunywa kwengalo ye-boom noma umzimba we-valve osebenza ngogesi, inani langempela aligcini nje ngokubumba into engenakwenzeka. Ubuqotho bezinto ezibonakalayo ngaphansi komthelela nokukhathala. Ngibone amaphethini e-wax ayinkimbinkimbi ahumusheka ekubunjweni okuhlulekile ekuhlolweni kwenkundla ngoba ukukhethwa kwe-alloy kuthathwe njengokucatshangelwa kwamuva. Inqubo iqala ngezinto, hhayi isikhunta. Izinkampani ezithola lokhu, njengokuthi I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), yiba nempilo ende yokubonisa yona. Iminyaka engamashumi amathathu kule niche kusho ukuthi babonile ukuthi ama-alloys asebenza kuphi. Ukugxila kwabo ku ama-alloys akhethekile-i-nickel-based for corrosion in slurry pumps, i-cobalt-based for wear face in crusher parts-kuwuphawu olubonisa ulwazi olusebenzayo, hhayi nje ibhulethi lebhukwana.
Kunombono oyiphutha oqhubekayo wokuthi ukufakwa kwe-investimenti kuyinqubo elungele ukuqeda. Akunjalo. Ikakhulukazi izingxenye zemishini. I-as-cast surface ingase ibe yinhle, kodwa indawo yokukhwelana ye-high-pressure seal? Ungalokothi. Yilapho ukusebenzisana ne-CNC machining kuba okungaxoxiswana khona. Asenzi nje ukulingisa; senza i-preform ye-near-net-shape yomshini obalulekile. Ngikhumbula iphrojekthi yesiphathi segiya leplanethi elihlangene. Ukulingisa kuthole ama-splines angaphakathi namaphakethe okonga isisindo, kodwa ubuso be-flange budinga ukubekezelela ukuvuleka okungu-0.05mm. I-Foundry eyayiphatha ukukhanda njengenkinga yomunye umuntu yabangela iphupho elibi lezinkinga zokuqondanisa. Isitolo esihlanganisa ukuhlelwa komshini kumklamo wokuqala wokulingisa, okuyindlela ehlanganisiwe oyibona ekusebenzeni okufana ne-QSY (isizinda sabo ku- tsngtaocnc.com ixhuma ngokucacile ukulingisa nokwenza imishini), konga izinyanga zekhanda elibuhlungu. Kuwumqondo ohlukile.
Lapho Isikhunta Igobolondo Lenza Khona Ukuma Kwaso (Futhi Lapho Ingenzi Khona)
Lokhu kuholela empikiswaneni yaphakade echungechungeni lokunikezwa kwemishini esindayo: ukukhishwa kwesikhunta segobolondo ngokumelene nokusakazwa kwe-investimenti. Akusona isigaba esilula. Kubakaki abakhulu, abalula uma kuqhathaniswa, abanodonga oluwugqinsi, isikhunta segobolondo siyashesha, sishibhile. Kodwa lapho usunama-cores angaphakathi, izindonga ezincanyana ezincikene nezingxenye eziwugqinsi, noma udinga ukwakheka okusanhlamvu kwe-metallurgical ephakeme, ukutshala imali kudonsela phambili. Igobolondo le-ceramic ngaphakathi ukutshala imali ivumela imininingwane emihle kanye nokulawula okupholisa okungcono.
Isibonelo sikakhonkolo: gqoka amapuleti ekhanda lokubhola idwala. Isikhunta seShell singasikhiqiza, kodwa ukungaguquguquki kokuqina nokucija kwemisele eqinile kwakuhlale kuwukugembula. Ukushintshela ekulingiseni utshalomali kulezi zingxenye ezigugileyo kusinikeze izinto ezibonakalayo ezibonakalayo, ezifanayo. Izindleko zengxenye ngayinye beziphezulu, kodwa ukuncipha kokwehluleka kwenkambu kanye nesikhathi sokuphumula somsebenzisi wokugcina kudale ukonga okuphelele. Yilokho ukubala okubalulekile. Imayelana nezindleko eziphelele zobunikazi, hhayi nje inani lentengo. Yilapho okuhlolwa khona ulwazi lomphakeli—ingabe angakuqondisa enqubweni efanele, ngisho noma kungeyona leyo ebonakala ishibhile ekuqaleni?
UDeveli Ngemininingwane: I-Gating, Shrinkage, kanye Neqiniso
Imidwebo ye-gating yezincwadi zokufunda ayinamsebenzi. Ngephuzu le-pivot elinokucindezeleka okuphezulu ku-excavator, awugcini nje ngokuphakela insimbi; uqondisa ukuqina ukuze udale ukugeleza okusanhlamvu okuzwakalayo emigwaqweni yomthwalo. Lokhu sikufunde kabuhlungu ngenqwaba yezikhali ezilengisiwe. Ama-castings amahle, adlula i-X-ray. Kodwa ekuhlolweni kokukhathala, baqhekeka endaweni ethile. Ukuhlaziywa kokwehluleka kukhomba iqoqo elincane le-porosity lapho ukucindezeleka okuqinile kwanda khona. Isango lalilungile ngokwezobuchwepheshe ukuze ligcwaliswe, kodwa lalingalungile empilweni yengxenye. Bekufanele sihlele kabusha isistimu yokugijima nesikhuphukeli, sengeze izindleko nesisindo ezindaweni ezingabalulekile ukuze sidonse ukuqina endaweni ebucayi. Kwasebenza.
Lona umnyombo ongathandeki womsebenzi. I-metallurgy, i-fluid dynamics, nokuhlaziywa kwengcindezi konke kuhlangana kugobolondo le-ceramic. Uhlu lwabahlinzeki insimbi futhi insimbi engagqwali iyisitolo sempahla. Leyo ekhuluma ngokuhlanganisa ukushisisa kwe-melt kanye nesikhunta sensimbi engagqwali eyi-duplex ukuze kuvinjelwe ukwakheka kwesigaba se-sigma sengxenye yezimayini yemvelo eyonakalisayo—lowo uzakwethu. Isethulo esifushane se-QSY sikhuluma ngomsebenzi wabo kulo lonke lolu chungechunge, kusukela kumabanga avamile kuya kuma-exotic. Lobo bubanzi buphakamisa ukuthi kudingeke baxazulule lezi zinkinga, hhayi nje ukuthela insimbi.
Ukwehluleka Njengomsebenzi Wokuphoqa
Awukakafundi ngempela ukutshala imali emishinini uze uqondise ukwehluleka. Okwangifundisa kakhulu kwakuyisethi yama-impeller epompo ye-heavy-duty dredge. I-Inconel 625, izindwani eziyinkimbinkimbi ngendlela emangalisayo. Baphase bonke iNDT. Izinyanga eziyisithupha ensimini, inhlekelele brittle ukuphuka. Umlandu? Izinto ezisele zegobolondo. Ucezu lwe-ceramic core, oluvaleleke ephasejini lokupholisa langaphakathi ebesicabanga ukuthi licacile, lidale indawo eshisayo futhi lashintsha i-microstructure yendawo ngesikhathi sokusebenza. Kwaba iphoyinti lenucleation lemifantu. Ukulungiswa akuzange kube ukuhlolwa okwengeziwe; bekuyinqubo enolaka futhi eqinisekisiwe yokukhishwa kwe-core. Manje, uma ngihlola umphakeli, ngibuza mayelana nezinqubo zabo eziyisisekelo zokususwa zamaphaseji angaboni. Impendulo ingitshela ngaphezu kwanoma yisiphi isitifiketi sekhwalithi.
Ukuhlanganisa ukuphela kwendlela eya phambili
Uma ubheka ukuma kwezwe manje, ikusasa alikho ezindlini zokulingisa ezizimele. Ama-OEM emishini yobunjiniyela acindezela izikhathi zokuhola futhi afuna umthwalo wemfanelo ogcwele. Imodeli ephumelelayo iwukuhlanganisa okuqondile: ukwenza iphethini, ukusakaza, ukwelashwa kokushisa, kanye nomshini wokunemba ngaphansi kophahla olulodwa, noma okungenani ngaphansi kokuxhumana okuqinile. Lokhu kulawula okuguquguqukayo. Lapho umakhi wemishini ethola ukuchezuka okuncane ekubumbeni, angakwazi ngokushesha impendulo kunjiniyela we-Foundry, futhi ukuthulula okulandelayo kuyalungiswa. Ukuhlukaniswa kwale misebenzi kungeza amaviki nezingqimba zokufiphala.
Yingakho imodeli yenkampani ithanda QSY kunengqondo. Ubungcweti babo obushiwo kukho kokubili ukubunjwa kwegobolondo futhi ukutshala imali, kuhlanganiswe CNC imishini, akulona nje uhlu lwesevisi. Kuwukuqaphela ukuthi ingxenye iwumkhiqizo wokugcina, hhayi ukulingisa. Iminyaka yabo engamashumi amathathu cishe isho ukuthi bavele besuka endaweni esungulwe baba ngabahlinzeki bezixazululo, ngoba imakethe yabaphoqa. Ngeke ukwazi ukuphila isikhathi eside kangako usebenzela umkhakha wemishini yobunjiniyela ngokwenza amaphethini amahle we-wax. Usinda ngokuqinisekisa ukuthi ingxenye efakwa amabhawodi emshinini ayibuyi.
Ngakho-ke, uma uhlola, bheka ngale kwegama elingukhiye. Bheka ubufakazi bokuxazulula izinkinga ezididiyelwe. Buza mayelana nokuziphatha kwe-alloy ethile kuhlelo lokusebenza olufanayo. Phenya ngendaba emayelana nokwehluleka kanye nalokho okufundiwe. Ubungcweti bangempela ku ukutshala imali kwezingxenye zemishini yobunjiniyela ingcwatshwe kuleyo mininingwane eyisihluku, esebenzayo, kude nezithembiso zokuthengisa ezicwebezelayo. Isisindo senkampani eneminyaka engu-30 ubudala esazivumelanisa nezimo, futhi ngokuzethemba okuthulile okuvela ekulungiseni okuphukile.
