Lapho onjiniyela becacisa a isihlabathi casting service factory ezingxenyeni zensimbi ezibaluleke kakhulu kumishini, azigcini nje ngoku-oda ukukhishwa-zivikela ukuqina kobukhulu ngaphansi kwemithwalo ye-hydraulic yamabha angu-300, ubuqotho be-microstructure ngemva kokwelashwa kokushisa, kanye nokungabekezeleli i-porosity ku-cobalt alloy nozzles. Lelo iqiniso esilibona nsuku zonke kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-isikhungo lapho ukufakwa kwesihlabathi kungeyona inqubo yokubuyela emuva kodwa isisombululo esinembayo sezingxenye ezingaphumeleli uma zichezuka ngo-0.05 mm.
Ukulingisa Kwesanti Okuhlangabezana Nezidingo Ezisebenzayo-Hhayi Ukuma Nje
Abathengi abaningi bacabanga ukuthi ukwenza isihlabathi kusho umsebenzi obiza kancane, onganembe kakhulu. Kodwa ezindlini zephampu ezinomfutho ophezulu noma amarola we-offshore winch centre shaft, ukukhishwa kwesihlabathi kuvame ukuba umzila *kuphela* osebenzayo oya ku-geometry enomumo wenetha ngaphambi kokuqedwa kwe-CNC—ikakhulukazi lapho ugqinsi lwezindonga lungaphezu kuka-120 mm noma imigodi yangaphakathi ifuna ama-cores angasalungiswa. Sibone amakhasimende eshintsha esuka ekutshalweni kwezimali aye ekubunjweni kwesihlabathi ngemva kokuqhekeka okwenzeke ngesikhathi sokwelashwa kokushisa kwe-AMS 5387: izinga lokupholisa elihamba kancane lokukhunta kwesihlabathi esiluhlaza kunciphise ukucindezeleka okushisayo ngo-40% kumabhulokhi angamasilinda asekelwe ku-T800.
Isizinda sethu esithobela i-ISO sisebenzisa isihlabathi sesilica esiboshwe ngamakhemikhali esinomswakama olawulwayo kanye nezilinganiso zokuhlanganisa—hhayi “isihlabathi esitholakalayo” esijwayelekile. Kungani kunendaba? Ngoba ukubumbana okungaguquki kuholela ekushintsheni kwesikhunta. Futhi ukushintshwa kwesikhunta kucekela phansi ama-callout e-GD&T kuma-flange wepompo ye-piston. Siqinisekisa yonke isikhunta ngokuskena okubonakalayo ngaphambi kokuthulula, bese silandelela ukuqondanisa okuyisisekelo sisebenzisa amaphoyinti ereferensi alinganisiwe—hhayi ukuhlola okubukwayo.
Lesi siqondiso sichaza ukuthi kungani ama-valve ethu okucindezela ebamba izilinganiso ze-ASME B16.34 Zekilasi 600 ngaphandle kokulungiswa kwe-weld yangemuva—nokuthi kungani ama-OEMs ezimoto zobunjiniyela ebuyela kuma-winch shafts esizukulwane sesibili anezincazelo eziqinile zokuphuma kwensimbi kune-oda lokuqala.
Lapho I-Sand Casting kanye ne-CNC Machining Kuhlangana khona
Abanye abahlinzeki baphatha ukulingisa kanye nokwenza imishini njengeminyango ehlukene. Siwaphatha njengochungechunge lwenqubo eyodwa eqhubekayo. Uma usithumelela umdwebo wepulaki ye-cobalt-nickel alloy, ithimba lethu libuyekeza idizayini yesango *ngokulandelana komshini wakho engqondweni*. Sibeka izikhuphukeli ukuze ukusethwa kokugcina kwe-CNC kugweme ukusikeka okuphazamisekile kuzo zonke izindawo ezinciphayo. Sigcina imininingwane ngomshini *ngaphambi* kokukhululeka kokugcina kwengcindezi—ukuze ukuhlanekezela kungawenzi umbiko wakho we-CMM.
Lokhu kuhlanganiswa kubaluleke kakhulu ezingxenyeni ezifana nezisekelo zephampu: ukusakazwa kwensimbi okunesigaba esisindayo okudinga ukugaya i-axis engu-3 ebusweni obuyisithupha, kanye nokubhobolwa kwe-deep-hole kumabhawodi afakwayo. Uma i-casting's as-cast flatness idlula u-0.8 mm/m, ukuqeda imishini kudla isabelo sesitoko—kanye nezingozi zokuveza ukuqina komhlaba ongaphansi. Ngakho-ke silawula isikhathi se-shakeout, ukupholisa ngokufanayo emigodini evalekile, futhi siqinisekisa ukucaba ngezigaba ezintathu: njengokusakazwa, ngemva kokukhululeka kwengcindezi, kanye nokukhanda kwangaphambili.
Umphumela? 92% isivuno sokudlula kuqala kuma-oda evolumu emaphakathi—awekho amalophu okusebenza kabusha, akukho ukuchezuka kobukhulu obumangalisayo ekuhlolweni kokugcina.
Ukulandelelwa Kwezinto Ongakuqinisekisa—Hhayi Ukuthi Ufune Nje
“Impahla eqinisekisiwe” isho okuncane ngaphandle kwalapho ungakwazi ukuyilandelela enombolweni yokushisa, ilogi encibilikayo, kanye nombiko wokuhlolwa kwe-tensile bar. Sithola wonke ama-cobalt alloys (okuhlanganisa ne-AMS 5387 ne-T800 amamaki) kusuka ezigayweni ezinesitifiketi se-EN 10204 3.1—futhi sigcina imibhalo egcwele kuyo yonke inkatho: ukuhlaziywa kwamakhemikhali, usayizi wokusanhlamvu nge-ASTM E112 ngayinye, kanye namavelu womthelela we-Charpy ku--40°C uma izicelo zasolwandle.
Asimane sigxivize u-“SS316” kumaka. Sifaka izinombolo zokushisa nge-laser kukho konke ukusakaza, sibhekisela kuzo kusistimu yethu ye-ERP ngokumelene namarekhodi okuhlola angenayo, futhi sihlanganisa imibhalo egcwele yokulandeleka namadokhumenti okuthunyelwayo. Iklayenti elilodwa lendawo kawoyela yaseNyakatho Melika lisebenzise le datha ukusula ukuhlolwa kwe-API Q1 ngaphansi kwemizuzu engama-45—akukho zicelo zokulandelela.
Futhi uma amakhasimende ebuza, “Ingabe ungakwazi ukuphinda inqwaba yangonyaka odlule?”—sidonsa ilogu yesithando somlilo efanayo, iqoqo lengxube yesihlabathi efanayo, inkatho efanayo yokuhlanganisa ingqikithi. Hhayi "okufanayo." Kuyefana.
Kungani Onjiniyela Bomhlaba Wonke Bakhetha Le Factory Yesevisi Yokusakaza Isihlabathi
Awudingi omunye umthengisi ocaphuna ngokushesha futhi alethe sekwephuzile. Udinga uzakwethu ohlaba umkhosi izingxabano ze-GD&T *ngaphambi kokuba* kuqale ukusebenzisa amathuluzi—njengokukhomba ukuthi ukubekezelela indawo okungu-±0.02 mm kubhore engu-200-mm-diameter kudinga ukwenziwa kwemishini yesibili, hhayi nje ukusakaza. Udinga ukucaciseleka kubashayeli besikhathi sokuhola: ukulungiselela isikhunta sesihlabathi kuthatha izinsuku eziyi-7; ukuguqulwa kwephethini kunezela 3; Ukwelashwa kokushisa kwe-AMS 5387 kwengeza u-10—hhayi “amaviki angu-2–4” ngaphandle kokwehlukana.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inikeza lokho kucaca. Abaphathi bethu bephrojekthi bakhuluma ubunjiniyela obushelelayo—hhayi i-jargon yokuthenga. Bazokutshela ukuthi kungani i-cobalt alloy nozzle idinga isipele segobolondo le-ceramic ku-cope, noma kungani ukusakazwa kwensimbi engagqwali okungaphezu kuka-80 kg kudinga umsizi we-centrifugal ukuze kube nomsindo. Azikho izithembiso ezingacacile. I-physics nje, i-metallurgy, nokulawulwa kwenqubo okubhaliwe.
Uma i-oda lakho elilandelayo lokulingisa isihlabathi kufanele lisebenze—hhayi nje ukufika—qala ngesibuyekezo sobuchwepheshe, hhayi ishidi lentengo. Umehluko ubonakala empilweni yasensimini, hhayi ephepheni kuphela.
