Ukutshalwa kwezimali kwefekthri yezingxenye zemishini yobunjiniyela akuyona nje inketho yokukhiqiza—iwukuphela kwendlela esebenzayo lapho ukuzinza kohlangothi, ubuqotho besakhiwo esincane, nokwethembeka kwendawo kufanele kuphile ama-hydraulic pulses amabha angu-300+ noma ukuguga okuqhubekayo emiphini yewintshi yezimayini. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., senze izindlu zephampu ye-cobalt alloy alloy ezingaphezu kuka-12,000 kusukela ngo-2019. Zonke ziphumelele u-100% wokuqinisekisa we-CMM kuma-callouts angu-±0.05 mm GD&T—futhi ziro ihlulekile ukuhlolwa kwengcindezi yokusebenza ku-1. Lokho kuvumelana akwenzeki ngengozi. Kwenzeka lapho ukukhishwa kwe-investimenti kungaphathwa njengenqubo, kodwa njengomcimbi we-metallurgical olawulwayo.
Kungani Ukutshala Kwezimali Kuwina Lapho Ukubuyiswa Kwesihlabathi Kuhluleka-Njalo
Izingxenye zemishini yobunjiniyela zisebenza ngaphansi kwemingcele engaxoxiswana nayo: izindlu ze-piston pump cylinder zifuna ukunemba kwangaphakathi kwekhonta ngaphakathi kuka-0.08 mm ukuvimbela i-cavitation; imizimba ye-valve yokucindezela idinga ukushuba kwezindonga ezivuzayo ngaphansi kuka-4.2 mm ngaphandle kwe-porosity; amarola e-winch center shaft abekezelela imithwalo ye-torsional engaphezu kuka-18,000 N·m kuyilapho ezungeza ngo-65 rpm ezindaweni ezigcwele uthuli. Ukulingwa kwesihlabathi akukwazi nje ukuletha leyo nhlanganisela. Ibhendi yayo yokubekezelela ejwayelekile ingu-±0.5 mm. Ubulukhuni bayo obuphezulu buphakathi kuka-Ra 12.5 μm—maholoholo kakhulu ezingxenyeni eziguquguqukayo zokuvala. Futhi ukwakheka kwayo okusanhlamvu akunakho ukulawula okuqondile, okumema i-micro-shrinkage voids eduze nezinyuka zokucindezeleka ezibucayi.
Ukutshala imali kuzixazulula zontathu. Ngokubunjwa kwamagobolondo e-ceramic okwakhiwe kusuka kumaphethini we-wax anembayo, sibamba u-±0.15 mm kuzici ezingafika ku-600 mm—ziqine kunezibonelelo eziningi zokuqeda i-CNC. Ukuqedwa okungaphezulu kushaya u-Ra 2.5–4.0 μm as-cast, okuqeda ukugaya kwesibili ebusweni obuvaliwe. Okubaluleke kakhulu, amaphrofayili ethu okuqinisa alawulwayo—atholwe ngokufakwa kahle kwesango, ukushisa kwegobolondo, kanye nemizila yokupholisa yesithando somlilo—akhiqiza izakhiwo ezinhle, ezifanayo ze-dendritic kuma-alloys asekelwe ku-T800 cobalt. Siqinisekise lokhu ngokuhlaziywa kwe-metallographic ekushiseni okungu-47 okulandelanayo: usayizi wokusanhlamvu wasala ungu-ASTM 6–7 kuyo yonke imingcele yenqwaba, ehlobana ngokuqondile nempilo yokukhathala ephakeme engu-22% ekuhlolweni kwe-winch shaft okusheshisiwe.
Ukuhlanganiswa Okuqondile Akuyona I-Buzzword-Kungumshuwalense Wakho We-Dimensional
Abanye abahlinzeki bangaphandle kokukhipha, ukukhanda imishini, nokwelashwa kokushisa. Asazi. Esikhungweni sethu se-Qingdao esiqinisekisiwe se-ISO 9001, yonke ingxenye ye-AMS 5387 igeleza ngokulandelana okukodwa okulawulwayo: impahla eluhlaza eqinisekisiwe → i-vacuum-arc ingot encibilikisiwe → ukufakwa kwe-investimenti → ukudambisa ingcindezi → i-CNC contouring ye-five-eksisi → ukugqama kwe-shot-penednet CMM. Kungani lokho kubalulekile? Ngoba ukunwetshwa kokushisa okushisayo akufani phakathi kokusakaza nokwenza imishini kubangela i-warpage efihliwe. Sayilinganisa: izingxenye ezenziwe ngomshini amahora angu-72 ngemva kokulingisa zibonise umnsalo ongu-0.032 mm endaweni engu-320 mm. Uma yenziwe ngomshini phakathi kwamahora angu-4 wokupholisa okulawulwayo? Umnsalo wehlele ku-0.007 mm—ngaphakathi kokucaciswa kokusebenza kwamarotha epompo anesivinini esikhulu.
Lokhu kuhlanganiswa kuphinde kuqede izikhala zokulandeleka. Inkatho ngayinye iphethe izitifiketi zezinto ezibonakalayo (ama-MTR), amalogi omlando oshisayo, futhi ihlanganisa imibiko yokulinganisa. Lapho i-OEM yaseYurophu ibika ukuguga kwesihlalo se-valve ngaphambi kwesikhathi, sikulandelele—hhayi kumakhemikhali engxubevange—kodwa ekushiseni okungahambisani negobolondo lokushiswa kwe-valve ngesikhathi esisodwa. Silungise iphrofayela yerempu yesithando somlilo, saphinda sasebenza ukuqinisekiswa, futhi saletha izingxenye ezishintshayo ngezinsuku eziyi-11. Akukho ukukhomba ngeminwe komuntu wesithathu. Akukho ukubambezeleka kwembangela yezinsuku ezingama-45.
Ukusebenza Komhlaba Wangempela Kwehlula Ukucaciswa Kwephepha-Njalo Ngasikhathi sinye
Amakhasimende abuza: “Ingabe ukusakaza kwakho kwe-investimenti kungakwazi ukubhekana nokuchayeka ngezikhathi ezithile okungu-450°C kumathuluzi okukhipha uwoyela negesi?” Siphendula ngedatha—hhayi izincwajana. Imibhobho yethu yengxubevange ye-T800 isebenze amahora angu-1,840 ezimeni ezilingisayo zekhanda lomthombo ngaphambi kokukhombisa ukuguguleka okulinganisekayo. Izimbangi ze-sandcast okulingana nazo zihlulekile emahoreni angama-620. Umehluko? Ukungabikho kokutshala imali kwe-mold-line flash kanye nokusabalalisa okuphezulu kwe-interdendritic carbide.
Siphinde silandelele izindlela zokuhluleka. Ngo-2023, u-92% wezingxenye ezinqatshiwe zavela ezindabeni ezihlobene nomklamo—hhayi amaphutha enqubo. Izigebengu ezivamile: izibopho eziklanywe kancane ezibangela ukugxilisa ingqondo kwengcindezi, ukushintsha okungabaliwe okubalulekile ezigabeni ezinezindonga ezincane, noma ama-callout e-GD&T angahambisani nokuziphatha kokushwabana kwegobolondo le-ceramic. Kungakho isibuyekezo sethu sobunjiniyela sihlanganisa impendulo yamahhala yokwenza izinto—izingozi zokuhlaba umkhosi njengokuthi “Lolu donga oluyi-0.8 mm lungase luqhekeke ngesikhathi sokuhliswa kwe-waxing” noma “Lokho ukubekezelela indawo okungu-±0.02 mm kudinga ukulungiswa kwe-CNC yangemuva.” Siyibamba ngaphambi kokuba iphethini yokuqala ye-wax isikwe.
Iphothifoliyo yethu iyakufakazela lokhu: amavalvu okucindezela ama-hydraulic excavators, izindlu zamasilinda zamaphampu odaka aphindwe kathathu, izisekelo zephampu zamayunithi okukhipha usawoti emanzini asogwini, nama-winch center shaft rollers ezimotweni zezimayini ezingamathani angu-50—konke kwenziwa ngokufaka utshalomali, konke kulethwe kushejuli, konke kuhlangana ne-ASME B16.34, ISO428, ISO428, kanye ne-ISO428
Ukukhetha Uzakwethu Olungile Wokusakaza Imali Kusho Ukubuza Imibuzo Enzima
Ungabuzi ukuthi "Ingabe uyawenza umsebenzi wokutshala imali?" Buza “Ukulawula kanjani ukujiya kwegobolondo kuphethini engu-450 mm?” Noma “Ingakanani isibalo sakho esiphezulu esivumelekile sokufakwa nge-ASTM E45 ngayinye ye-AMS 5387?” Noma “Ngibonise imibiko yakho yokugcina emithathu ye-CMM engxenyeni enama-callouts angu-≥12 GD&T.”
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY, sishicilela lezo zimpendulo—hhayi kumadekhi wokumaketha, kodwa kumarekhodi okukhiqiza. Sitshala kuma-CMM ebanga le-metrology anamathebula egwadle esinxephezelelwe ngokushisa, hhayi izikena zedeskithophu. Silinganisa yonke i-thermocouple yesithando somlilo nsuku zonke—hhayi maviki onke. Sigcina amasampula ezinto ezingavuthiwe iminyaka eyi-10—hhayi izinyanga eziyisi-6.
Ukutshala imali embonini yezingxenye zemishini yobunjiniyela akukhona ukuthola umdayisi. Imayelana nokuthola isandiso sobuchwepheshe sethimba lakho lonjiniyela—elikhuluma kahle nge-metallurgy, i-GD&T, kanye nefiziksi yokwehluleka komhlaba wangempela. Lelo izinga esihlangabezana nalo. Zikhathi zonke.
