Uma uzwa ukukhishwa kwesihlabathi ngokushesha, umcabango osheshayo yijubane. Leso isithembiso, akunjalo? Kodwa ku-Foundry, okusheshayo yigama elihlobene. Akukhona nje ngokushaya ndawonye isikhunta nokuthela insimbi. Inselelo yangempela ukufeza lelo jubane ngaphandle kokudela ubuqotho, okuyilapho izitolo eziningi, ngisho nabanamava, zingakhubeka khona. Bajaha iwashi futhi bagcine benezilinganiso ezilahliwe ezidla zonke izinzuzo ezicatshangwayo zokusebenza kahle. Sekungamashumi eminyaka ngizungeze amaphethini nemigqa yokubumba, ngiwubonile umjikelezo-ukucindezela kokushintsha ngokushesha kuvame ukungazinaki izinyathelo eziyisisekelo ezenza isivinini siqhubeke.
Umnyombo Wokukhiqiza Okusheshayo Kweqiniso
Ngakho-ke, yini esebenzayo ukukhishwa kwesihlabathi ngokushesha ubukeke phansi? Iqala kudala ngaphambi kokuthi isihlabathi sixutshwe. Impahla yephethini iyinkosi. Uma usebenzisa amaphethini agugile, enziwe ngokhuni aklanyelwe umsebenzi wevolumu ephansi, awusoze wazuza imijikelezo engaguquki, esheshayo. Ukushintshela kumaphethini e-urethane aphakeme kakhulu noma ensimbi anemidwebo efanele kanye nesango elihlanganisiwe akunakuxoxiswana ngalo. Ngikhumbula iphrojekthi yochungechunge lwezindlu zamaphampu lapho sashintsha khona amaphethini amadala okhuni saya kuma-aluminum anomshini. Ukutshalwa kwezimali kokuqala bekubalulekile, kodwa ukuncishiswa kwesikhathi sokulungiselela isikhunta kanye nokwehla okukhulu kweziphambeko eziyinhloko zamashifu kukhokhele ngaphansi kwezinyanga eziyisithupha. Ijubane lavela ekuthembekeni, hhayi nje ukuhamba ngokushesha.
Bese kuba nesistimu yesihlabathi ngokwayo. Ukubumba kwesihlabathi esiluhlaza kuthola ukunakwa, kodwa ngokukhiqiza kwangempela okusheshayo, kwevolumu ephezulu, isistimu yesihlabathi ehlanganiswe kahle ngamakhemikhali ivamise ukuphumelela. Isihluthulelo siwukulawula inqubo—ukuqapha izinga lokushisa lesihlabathi, izilinganiso ze-binder, nokusebenza kahle kwezixube ngokwenkolo. Ukweqiwa lapha akumane nje kukubambezele; kudala inqwaba yamaphutha. Lokhu sikufunde kanzima ekugijimeni kubakaki bezimoto. Ushintsho oluncane lomswakamo lwesizini luchithe isikhathi sethu sokusetha i-catalyst, okuholele eqoqweni lokukhunta elinamabala athambile. Inqubo esheshayo yafika kuma ukugaya ukuze kulungiswe kabusha. Ijubane lintekenteke; yakhelwe phezu kwetshe lezinto eziguquguqukayo ezilawulwayo.
Kulapho-ke ulwazi lukazakwethu osenesikhathi eside lubalulekile. Inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), enomlando wayo weminyaka engu-30 ekulingiseni, ikuqonda ngokujulile lokhu. Abavele bathengisile nje; baphatha lezi zinqubo eziyinkimbinkimbi. Uma uphusha imijikelezo esheshayo, ukuba nomhlinzeki owazi ukulinganisa izici zengxubevange—njengokugeleza kwensimbi ethile engagqwali noma amandla ashisayo engxubevange esekelwe ku-nickel—nezimo zokubumba kubaluleke kakhulu. Ubungcweti babo kugobolondo nokufaka utshalomali bazisa umsebenzi wabo wokuphonsa isihlabathi, kugcizelela ukuthi ukwakheka kwenqubo okunembayo kwenza isivinini sikwazi kanjani.
Ukugada, Ukudla, kanye Nesikhathi Esifihliwe Kuyacwila
Uma ukwenza isikhunta kuwumzimba wokusakazwa ngokushesha, uhlelo lokungena kanye nokudla luwuhlelo lwezinzwa. Lena indawo evuthwe ukungaqondi kahle. Iphutha elivamile ukumane wehlise isistimu yokufaka isango kusuka enqubweni ehamba kancane. Ngoba ukukhishwa kwesihlabathi ngokushesha, udinga isistimu edizayinelwe amazinga okugcwalisa asheshayo ukuze ugweme isiyaluyalu, kodwa futhi ebangela amandla okuqinisa ahluke. Ukulingiswa kwekhompyutha sekushintshe umdlalo lapha, kodwa akulona ichashazi lomlingo. Usadinga ukwahlulela okusebenzayo ukuze utolike imiphumela futhi ulungisele okuguquguqukayo komhlaba wangempela njengomehluko omncane wokungena kwesihlabathi.
Ngikhumbula ngenza i-prototyping ikhava ye-gearbox nge-ductile iron. Ukulingisa kwakubukeka kuphelele—ukugcwalisa kwakubushelelezi, ama-feeders ayenosayizi owanele. Kodwa ekukhiqizeni, sasilokhu sithola i-shrinkage porosity engxenyeni ewugqinsi. Ukulingisa kucabange ukupholisa okufanele. Eqinisweni, umjikelezo wethu wokubumba osheshayo wawusho ukuthi isikhunta sisafudumala kancane kusukela ekutheleni kwangaphambilini, ukuguqula isikhathi sokuqina sendawo. Ukulungisa kwakungekona ukwehlisa ijubane; kwakuwukwengeza ukugodola okuncane, kwangaphandle kuleyo ndawo ethile yesikhunta. Isixazululo sasilula, kodwa ukusixilonga kwakudinga ukuxetshulwa emuva kwezingqimba zenqubo esheshayo ukuze ubone indawo yangempela eshisayo. Isikhathi esilondolozwe ekubumbeni singalahleka ekwenzeni uma ikhwalithi yangaphakathi ingekho.
Lokhu kuhlotshaniswa ngqo nemisebenzi yesibili. Inqubo eshesha ngempela ibheka ukwenza imishini njengengxenye yokuqhubeka. Isibonelo, ikhono lokuhlanganisa le-CNC le-QSY liyingxenye ebalulekile. Uma bekhiqiza ingxenye ye-sand-cast, sebevele baklama ukusakaza becabanga ngama-machining datum kanye nezibonelelo zesitoko. Lokhu kuqondanisa kuvimbela isimo esivame kakhulu lapho ukulingisa okukhiqizwa ngokushesha endaweni okutholakala kuyo kuba ibhodlela esitolo somshini ngenxa yokuqina kodonga okungahambisani noma izindawo ezingezinhle zedatha. Umsebenzi wabo onama-alloys akhethekile afana ne-cobalt-based kugcizelela nakakhulu lokhu; awukwazi ukuphonsa ngokushesha ingxubevange eyinkimbinkimbi, esebenza kanzima bese uchitha isikhathi ngokuthola ukuthi uyibamba kanjani ukuze uyigaye. Izinqubo kufanele zenziwe ngokuhlanganyela.
Izinketho Zezinto Ezibalulekile: Imikhawulo Yesivinini kanye Nezinsiza
Akuwona wonke ama-alloys adalwe alingana nokukhiqizwa okusheshayo. Izinsimbi ezivamile nezinsimbi ezinekhabhoni ephansi zithethelela ngokuqhathaniswa. Kepha uma ungena endaweni yezinsimbi ezine-alloy ephezulu, i-stainless, noma uhlu lwama-superalloy QSY, umdlalo uyashintsha. Isici esisheshayo lapha sincane mayelana nomjikelezo wokuthulula kanye nokunye okukuzungezile. Lezi zinto zivame ukudinga ukushisisa kwangaphambili kwesikhunta, izinga lokushisa elilawulwayo lokuthulula ngaphakathi kwefasitela elincane kakhulu, kanye nezinqubo zokupholisa ezithile zokuvimbela ukuqhekeka noma izigaba zensimbi ezingathandeki.
Ukuzama ukusebenzisa umjikelezo osheshayo ojwayelekile engxenyeni yensimbi engagqwali eyi-duplex, isibonelo, kuyindlela yokwenza inhlekelele. Okuqukethwe okuphezulu kwe-chromium ne-molybdenum kukwenza kuthambekele ekuhlukaniseni nasekwakhekeni kwesigaba sesibili uma ukuqina kungaphathwa ngendlela efanele. Ungakhiqiza isikhunta njalo ngemizuzwana engama-90, kodwa uma u-30% wokusakazwa edinga ukwelashwa okubanzi noma ukulungiswa, ulahlekile. Ikhono langempela ku ukukhishwa kwesihlabathi ngokushesha ngalezi zinto ukwazi ukuthi ungasheshisa kuphi (njengokuhlanganisa okuwumongo noma ukuphatha isikhunta) nalapho kufanele usebenzise khona ukulawula ngamabomu (njengokuthela nokupholisa). Kuyisigqi, hhayi ukugijima.
Lena enye indawo lapho ukujwayelana kwezinto ezijulile kuzuza khona. I-Foundry ejwayele ukuphatha ama-alloys asekelwe ku-nickel ekutshalweni kwezimali, njenge-QSY, iletha umqondo oqinile kusayensi yezinto ezibonakalayo ezuzisa imisebenzi yayo yokuphonsa isihlabathi. Baqonda amaphrofayili okushisa kanye nezici ze-fluidity ngaphakathi. Lokhu kusho ukuthi uma iklayenti liza nesicelo sesibonelo esisheshayo ku-17-4 PH engenasici, lingakwazi ukwenza izinqumo ezinolwazi mayelana nedizayini yesango kanye namazinga okupholisa kusukela osukwini lokuqala, ligwema isilingo nephutha elibulala imigqa yesikhathi.
Lapho I-Rapid Ihluleka: Izifundo ezivela Phansi
Ayikho ingxoxo eqotho ngaphandle kokukhuluma ngokwehluleka. Ukuphishekela isivinini kuye kwaholela kwezinye izifundo ezibiza kakhulu. Okukodwa okugqamile kwakuyi-oda lamakhulu amaningana amabakaki okuthutha. Ukuze sihlangabezane nomnqamulajuqu oqinile, sigunyaze isinqamuleli: ukusebenzisa ingxube yesihlabathi ebuyisiwe enokuqukethwe kwenhlawulo ephezulu kunokuvamile ukusheshisa ukukhiqizwa kwesikhunta. Umbono wawuwukuthi isikhunta sasiyohlubula kalula. Iqiniso laliwukuthi ukuncipha kokungena kwamanzi kubangele ukonakala kwegesi nezibazi zokungena kukho konke ukusakaza okukodwa. Isikhathi esilondolozwe ekubunjweni saphindwa ngokuphindwe kashumi ekuhlanzeni, ekulungisweni kokushisela, futhi ekugcineni, kuncibilika ingxenye enkulu yokugijima. Kwakuyisikhumbuzo esingaguquguquki sokuthi ekubunjweni kwesihlabathi, izici zesikhunta zingcwele. Awukwazi ukukopela isihlabathi.
Omunye umgodi wakudala wukuzenzakalela ngokweqile kusenesikhathi. Ukutshala imali kumugqa wokubumba onesivinini esikhulu womndeni womkhiqizo ongakaqinisekiswa ngokugcwele kuyingozi enkulu. I-automation idinga ukungaguquguquki okuphelele kumishini yephethini, ubukhulu obuyisisekelo, nekhwalithi yesihlabathi. Noma yikuphi ukuhluka kuba yizitobha. Ngibone imigqa efakiwe lapho ithimba lonjiniyela lidizayinelwe umhlaba okahle, futhi ithimba lokukhiqiza lichithe unyaka lilwela ukwenza izingxenye zomhlaba wangempela zilingane ngaleyo ndlela. Kwesinye isikhathi, inqubo ye-semi-automated, eqondwa kahle ishesha ngokweqiniso kune-automated ngokugcwele, ehlushwa inkinga. Isivinini kumele sibhalwe ngezigaba.
Lokhu okuhlangenwe nakho kwakha indlela eqinile yokubhekana nayo ukukhishwa kwesihlabathi ngokushesha. Kungakho ukusebenzelana nomakhiqizi osemnkantshubomvu akukona nje ukukhishwa kwemisebenzi; kumayelana nokusebenzisa isilingo sabo esiqoqiwe kanye namaphutha. Inkampani enokuphila isikhathi eside kwe-QSY ngokungangabazeki izule kulokhu kwehluleka futhi yabhaka izifundo ezinqubweni zayo zokusebenza ezijwayelekile. Uma becaphuna ukuguqulwa okusheshayo, kusekelwe ohlelweni oluqinisekisiwe, olulawulwayo, hhayi nje izikhathi zomjikelezo womshini onethemba.
Ukubuka Okudidiyelwe: Ukusakaza Njengesixhumanisi Kuchungechunge
Ekugcineni, imisebenzi esheshayo ephumelela kakhulu yokuphonsa isihlabathi yileyo engaboni le nqubo njengesenzakalo esiyingqayizivele kodwa njengesixhumanisi sokuqala ochungechungeni lokukhiqiza. Umgomo awukona nje ukuthela ngokushesha; ukulethwa okusheshayo kwengxenye eqediwe, esebenzayo. Lokhu kudinga ukuhlanganiswa. Idizayini yokulingisa ikusiza kanjani ukulungisa okusheshayo kumshini wokugaya we-CNC? Ukubekezelela okucacisiwe ezindaweni ezingabalulekile kuvimbela kanjani ukudlula komshini okungadingekile? Ukupakishwa kuzivikela kanjani izingxenye ze-swift logistics?
Lo mbono ophelele yiwo ohlukanisa isitolo somsebenzi nozakwethu wangempela wokukhiqiza. Kungumehluko phakathi kokuthi yebo, singakwenza kusheshe futhi yebo, singakuyisa kulayini wakho wokuhlanganisa ngokushesha futhi silungele ukukufaka. Lokhu kwakamuva kudinga amakhono okugqamisa kwe-QSY: ubungcweti bokusakaza obushadiswe ngokunemba kwemishini, konke ngaphansi kophahla olulodwa. Ngokusakazwa kwesihlabathi ngokushesha, lokhu kuhlanganiswa kuyisisheshi sokugcina. Iqeda ukubambezeleka kanye nokukhombana ngomunwe okwenzeka lapho ukulingisa nomshini kuhlukaniswa.
Ngakho, uma ngicabanga ukukhishwa kwesihlabathi ngokushesha manje, ngicabanga kancane ngesitophuwashi emugqeni wokubumba kanye nokunye mayelana nenani lomugqa wesikhathi kusukela ku-oda kuya engxenyeni efakiwe.
