Ake sikhulume nge-prototype yokusakazwa kwesihlabathi. Ngelinye lalawo magama akhulunywa kakhulu, ngokuvamile nokungaqondi kahle. Abantu bezwa i-prototype futhi bacabange ngokuphrinta kwe-3D noma ukwenziwa kwemishini enesivinini esikhulu, into ethambile nedijithali. Bese bezwa ukukhishwa kwesihlabathi kanye nesithombe esikhulu, ukukhiqizwa kwe-gritty kugijima kumabhulokhi enjini. Umlingo wangempela, kanye nenselelo yangempela, kwenzeka lapho leyo miqondo emibili ihlangana khona. Akukhona ukwenza ucezu olulodwa oluphelele elebhu; kumayelana nokwenza ingxenye esebenzayo, evivinywayo eziphatha ngendlela ezokwenza inguqulo yokugcina yokukhiqiza, kusetshenziswa umndeni ofanayo oyisisekelo wezinqubo. Umgomo akuwona nje umumo—uyisakhiwo sempahla emele, ama-engeli asalungiswa, isiphetho esingaphezulu, kanye nazo zonke izingqinamba ezivela ekutheleni insimbi esikhunjeni sesihlabathi. Izikhathi eziningi kakhulu ngibone amaphrojekthi ema ngoba i-prototype yenziwe ngenqubo ehluke ngokuphelele, futhi idatha evela ekuhlolweni ayizange ihumushe. Leyo yigebe lesibonelo sokulingisa isihlabathi esihlose ukulivala.
I-Core Idea: Ukwethembeka Ngaphezulu KwesiPolish
Inani eliyisisekelo lokusebenzisa ukulingwa kwesihlabathi kwesibonelo ukwethembeka. Uzibophezela kumaqiniso ohlelo kusenesikhathi. Uma ingxenye yakho yokugcina kuzoba ukuphonsa kwesihlabathi, khona-ke i-prototype yakho kufanele ibe njalo. Lokhu kuphoqa ukuklama kwezingxoxo ze-manufacturability (DFM) ukuthi zenzeke ekuqaleni, hhayi njengokucatshangelwa kwamuva. Uzobona lapho okudinga khona okusalungiswa, uzozwa isisindo sensimbi, uzoqonda mathupha isango lokuphuma kanye nezinselelo ezikhuphukayo. Uthisha ononya kodwa oqotho. I-prototype ye-billet eyenziwe ngomshini kahle ingase ibukeke iphelele edeskini, kodwa ayikutsheli lutho ngokuthi insimbi izogeleza kanjani esikhunjeni, lapho ukuncipha kwe-porosity kungenzeka khona, noma uma ukuguquguquka kokuqina kodonga lwakho kunzima kakhulu kwinqubo yokusungula.
Ngikhumbula iphrojekthi yobakaki okhuphukayo wocezu lwamathuluzi embonini. I-prototype yokuqala yeklayenti bekuyi-CNC eyenziwe ngomshini kusuka kupuleti le-aluminium eliqinile. Kwanele, kwasebenza. Bakhanyisa ithuluzi lokusakaza ngengcindezi ephezulu. Amashothi okuqala avela kumshini wokukhiqiza ayegcwele izivalo ezibandayo kanye nokugcwalisa okungaphelele. Kungani? I-prototype eyenziwe ngomshini yayinamakhona angaphakathi abukhali, ayisikwele okwakungenakwenzeka ukuthi insimbi encibilikisiwe igcwale ngesivinini esikhulu. Ukukhishwa kwesihlabathi okuyisibonelo esilula, ngisho nesiqinile, bekungahlaba umkhosi ngokushesha leyo geometry njengenkinga. Besizobona isidingo samaradi. Yilolo hlobo lwesifundo esibiza amashumi ezinkulungwane ngokufa okusetshenzwe kabusha.
Kulapho uzakwethu onolwazi olunzulu lwe-Foundry engaxoxiswana khona. Udinga umuntu ongabheka imodeli ye-CAD futhi abone ngokushesha isikhunta, umugqa wokuhlukanisa, ama-cores. Inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ngeminyaka yabo engu-30 ekulingiseni, isebenza kulesi sikhala ngendlela enembile. Akukhona nje ukwenza isikhunta; imayelana nokweluleka ngokuthi ungayilungisa kanjani idizayini ukuze isikhunta senze i-prototype—futhi ngokwengeza, ingxenye yokugcina—iphumelele. Umsebenzi wabo ngaphesheya ukubunjwa kwegobolondo, ukufakwa kwe-investimenti, nama-alloys ahlukahlukene kusho ukuthi bayawuqonda uhlaka, ngakho bazi kahle ukuthi nini futhi kungani kufanele bancome isihlabathi se-prototype.
Inqubo: Iyashesha, Ingcolile, futhi Ifundisa
Ngakho-ke, isebenza kanjani ngempela isikhathi esisodwa noma esifushane? Ivamise ukuba yinqubo eyenziwa ngesandla noma eye-semimanual. Awakhi iphethini eqinile, esebenziseka kabusha yomshini wokubumba. Ngokunokwenzeka, wenza iphethini elihle elisuka endaweni efana nebhodi le-urethane noma igwebu elinomthamo omkhulu. Leli phethini libe selisetshenziselwa ukwakha isikhunta sesihlabathi, ngokuvamile kusetshenziswa uhlelo lwesihlabathi esingabhaki ngesivinini. Isikhunta singase sibe indlela elula enezingxenye ezimbili zokubhekana nokuhudula, noma singadinga izingcezu ezixekethile. Okugxilwe ekuthwebuleni ijiyomethri, hhayi ekutholeni isiphetho sezinga lokukhiqiza.
Ukukhetha insimbi kubalulekile. Ufuna ukufanisa, eduze ngangokunokwenzeka, i-alloy ehloselwe ukukhiqizwa. Uma ingxenye yokugcina kufanele ibe yi-iron ductile, i-prototype yakho kufanele ithululwe ku-ductile iron. Lokhu kuhlola uketshezi lwaleyo ngxubevange ethile, izinga lokushwabana kwayo, izidingo zayo zokudla. Ukuthela i-prototype nge-aluminium lapho ukukhiqizwa kuzoba insimbi cishe akusizi ngalutho ngokombono wezinto ezibonakalayo. Lena enye indawo lapho ubuchwepheshe be-Foundry bubalulekile. Okuhlangenwe nakho kwe-QSY nge insimbi, insimbi, insimbi engagqwali, futhi ekhethekile ama-alloys asekelwe ku-nickel kusho ukuthi bangakuqondisa kokubalulekile, ngisho nesibonelo. Amandla okushisa okuthululela i-superalloy yizwe elingaphandle kwe-iron empunga.
Umphumela ubaluleke njengokuthela. Nithintitha okubunjiweyo, ninqume amasango nezikhuphukeli, bese nibona ngempela lokho eninakho. Ukubukeka kokuqala kuhlala kusho. Ungase ubone indawo eshwabene ebonakalayo engxenyeni ewugqinsi, okuqinisekisa ukuthi udinga isikhuphukeli esikhulu. Ungase ubone isihlabathi sivutha engxenyeni encane, ebonisa ukuthi insimbi ibishisa kakhulu noma ingxenye izacile kakhulu ukuthi ingagcwaliswa kahle. Lena impendulo eluhlaza, esheshayo. Bese wenza ukuhlanza okuncane—mhlawumbe ukuqhuma okusheshayo nokudlula umugqa wokuhlukanisa ngegrinder—okwanele nje ukuze ukwenze kusebenze ekuhlolweni. Umgomo uwukufaka emshinini noma emshinini ukuze ubone ukuthi uyasebenza, futhi okubaluleke nakakhulu, ukuthi yehluleka kanjani uma kwenzeka.
Lapho Kuyithuluzi Elilungile (Futhi Uma Kungelona)
I-prototype ye-sand casting iyakhanya kwezinye izinhlelo zokusebenza. Izingxenye ezinkulu, eyodwa. Ngokuvamile kuwukuphela kwendlela engabizi kakhulu yokwenza ikhophi yengxenye eyimitha noma ngaphezulu ngosayizi. Izingxenye ezisindayo zingelinye ikhandidethi elihle, njengoba ezinye izindlela zokulinganisa ezisheshayo zilwa namavolumu ensimbi eqinile. Ilungele futhi izingxenye ezinemigodi yangaphakathi eyinkimbinkimbi edinga ama-sand cores. Ungakwazi prototype inqubo core-making ngokwayo. Futhi-ke, kubalulekile lapho izinto ezibonakalayo ze-casting alloy zibalulekile ekuhlolweni, njengokumelana nokushisa kwe ingxubevange esekelwe cobalt noma ukumelana nokugqwala kwebanga elithile elingenabala.
Kodwa akuyona i-panacea. Ezingxenyeni ezincane kakhulu, ezinemininingwane eminingi enokubekezelelana okuqinile, ukufakwa kwe-investimenti kungase kube umzila wesibonelo ongcono, ngisho nengxenye yokukhiqiza ye-sand-cast, ukuze nje uhlole ukulingana nesimo. Uma udinga ishumi nambili lama-prototypes acishe afanayo eqeqebana lokuhlola, ezomnotho zingakusunduzela ekukhunjweni okuhlala isikhathi esifushane noma ngisho nokwenza imishini. Futhi uma ukuphela kwendawo noma ukunemba kobukhulu kuwukukhathazeka okuyinhloko kokuhlolwa, khona-ke ungcono kakhulu ekwenzeni imishini. Amandla okwenziwa kwesihlabathi okuyisibonelo ukuhlola ukwenziwa kanye nokusebenza kwenqwaba kokusebenza kwedizayini ehloselwe ukufakwa kwesihlabathi.
Isibonelo esisebenzayo: sake sasebenza ku-prototype yedizayini entsha ehlukahlukene. I-geometry yayiyinkimbinkimbi, inezigaba eziphambanayo. Indlela yokukhiqiza kwakuwukubumba amagobolondo. Sisebenzise i-prototype sand cast (ngempumelelo indlela yesihlabathi esiluhlaza) ukuze sihlole umklamo oyisisekelo. I-prototype yembula inkinga enkulu yesiyaluyalu endimeni eyodwa ebingaholela ekwakhekeni kukamanye. Sidizayine kabusha isistimu yomgijimi ngokusekelwe kulowo mfanekiso othelayo owodwa. Lapho kamuva sathuthela kwangempela ukubunjwa kwegobolondo inqubo yokukhiqiza kwangaphambili, leyo nkinga yayisivele ixazululiwe. I-prototype ayizange ibukeke kahle, kodwa ilondoloze iphrojekthi.
Izithiyo Ezibambekayo kanye Nezinqumo Zangempela
Akuqondile konke. Enye yekhanda elikhulu kakhulu ukwenza iphethini. Ukuze uthole okukodwa kweqiniso, ukucekela phansi iphethini eyenziwe ngomshini esikhunjeni kuyamukeleka. Kodwa uma ucabanga ukuthi ungase udinge ukuthululwa okubili noma okuthathu ukuze uphindaphinde, udinga iphethini eqinile. Lokho kukhuphula izindleko zokuqala nesikhathi. Kukhona ukuhwebelana okuqhubekayo: sitshala malini kumathuluzi esibonelo (iphethini) uma kuqhathaniswa nokuthola nje insimbi esandleni?
Elinye iphuzu elicashile yisihlabathi ngokwaso. Izikhungo zokukhiqiza zisebenzisa isihlabathi esilawulwa ngokuqinile, esigaywe kabusha esinezithasiselo ezithile. Isitolo se-prototype singasebenzisa isistimu yesihlabathi ehlukile, eguquguqukayo. Izici ezishisayo ziyehluka. Lokhu ngezinye izikhathi kungase kubangele ukuhluka okuncane kumazinga okupholisa nokuthungwa kwendawo uma kuqhathaniswa nenqubo yokugcina yokukhiqiza. Kufanele ukuqaphele lokhu futhi ungatoliki ngokweqile ukungezwani okuncane kwendawo. Izakhiwo eziwumgogodla, noma kunjalo, kufanele zilawulwe yinsimbi, hhayi isihlabathi.
Isikhathi sokuhola singesinye isici. Kuyashesha kunokwakha amathuluzi okukhiqiza, kodwa akuhambi nje ngobusuku obubodwa. Unokwakhiwa kwephethini, ukuhlanganisa isikhunta, ukuthulula, ukupholisa, nokuthuthumela. Umugqa wesikhathi ongokoqobo wengxenye eyinkimbinkimbi emaphakathi amaviki amabili kuya kwamane. Yilapho-ke ukuhlela kubalulekile. Isigaba esidinga ukuhlonishwa kushejuli yokuthuthukiswa komkhiqizo, hhayi umzuzu wokugcina, sidinga ingxenye yensimbi.
Ukuhlanganisa nezinyathelo ezilandelayo: CNC kanye Beyond
Akuvamile ukuthi i-prototype ye-sand casting iqonde ngqo ekuhlolweni ngaphandle komshini othile. Leso isixhumanisi semvelo sochungechunge lwesevisi olugcwele. Cishe ngaso sonke isikhathi uzodinga ukufaka ubuso bedatha ebucayi ngomshini, izimbobo zamabhawodi, noma izindawo zokuvala ukuze uthole ukuhlolwa okunembile. Yingakho imodeli yenkampani enikeza kokubili ukusakaza kanye CNC imishini inamandla kakhulu. Bangakwazi ukuphatha iluphu yonke: ukubuyekezwa kwedizayini, ukwenziwa kwephethini, ukuthulula, ukunyakazisa, ukwelashwa kokushisa uma kudingeka, bese kwenziwa imishini enembayo yezici ezibalulekile ekubunjweni okufanayo okumahhadlahhadla.
Le ndlela edidiyelwe iqeda inani elikhulu lokungqubuzana kwezinto kanye nokungaxhumani kahle. Umakhi akaqageli ukuthi indawo yangempela ikuphi ekubunjweni okungalungile; bayingxenye yeqembu elifanayo eliphumelele. Esikhungweni esifana ne-QSY (https://www.tsingtaocnc.com), lokhu ukuhamba komsebenzi okujwayelekile. I-prototype iphuma ku-Foundry, idutshulwa iqhume, bese ithuthela esitolo semishini. Banemodeli yokuqala ye-CAD, futhi bayazi ukuthi yiziphi izici ezisakazwayo futhi ezidinga umshini ukuze zicaciswe. Lokhu kuqhubeka kubaluleke kakhulu ekugcineni ubuqotho be-prototype nokuqinisekisa ukuthi imiphumela yokuhlolwa inengqondo.
Ekugcineni, i-prototype iba yisisekelo senqubo yokukhiqiza. Isistimu yokufaka isango oyiqinisekisile, ukubekwa kwesikhuphukeli okuqinisekisile, idizayini ewumgogodla oyihlolile—lonke lolo lwazi lungena ngqo ekwakhiweni kwephethini yokukhiqiza kanye nesikhunta. Isigaba sokusakazwa kwesihlabathi somfanekiso owenziwe kahle asivezi nje ingxenye yokuhlola; iveza umhlahlandlela wenqubo. Isusa engcupheni ukutshalwa kwezimali kwamathuluzi okubiza kakhulu okulandelayo. Iguqula okungaziwa komklamo omusha kube amanani aziwayo, noma okungenani, kube ukuqagela okufunde kakhulu. Futhi kuleli bhizinisi, ukuqagela okufundile kuvame umehluko phakathi kokuqaliswa okushelelayo kanye nokwehluleka okubizayo.
