Xa iinjineli zichaza a metal casting Foundry factory kwi-high-pressure valves hydraulic valves okanye izindlu zempompo ze-cobalt-alloy, azithengi nje iindawo-ziqinisekisa ukuzinza kwe-dimensional phantsi kwe-350 bar, ingqibelelo ye-microstructural emva kokunyanga kobushushu, kunye nokunyamezela kwe-porosity kwiindlela ezibalulekileyo zokuhamba. Siye sabona iiprojekthi ezininzi zilibazisekile-kungekhona ngeziphene zoyilo, kodwa ngokungafaniyo kokufunyanwa kwezakhono: iivenkile ezithengisa isanti ezizama i-AMS 5387 cobalt alloy; Iivenkile ze-CNC kuphela ezamkela izithuba ezivaliweyo nge-0.8 mm yezibonelelo zomatshini; abasasazi bacaphula amaxesha okukhokela ngaphandle kokuqinisekisa isiqinisekiso sezinto ezikrwada. Ukwenziwa kokuchaneka kuqala kwakudala phambi kokuba kugalelwe okanye kusikwe okokuqala.
Kutheni ukudityaniswa kwe-Casting-Machining kungaxoxiswana kwiMishini-Amacandelo abalulekileyo
Uninzi lweentsilelo zibuyela emva ekuqhubeni i-handoffs. Umzimba wevalvu ofakwe kwisanti eluhlaza unokuhlangabezana nemilinganiselo yobunzima-kodwa ukuqina kwayo komphezulu wokuphosa kuyahluka nge-±40 HB kwindawo enye. Oko kungangqinelani kunyanzelisa ukususwa kwesitokhwe se-CNC esinobundlongondlongo, kubeka emngciphekweni iindonga ezibhityileyo kwiindawo zokutywinwa koxinzelelo. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Silawula zombini ukuphosa kunye nomatshini phantsi kophahla olunye oluhambelana ne-ISO. Umgca wethu wokulahla wesanti wondla ngokuthe ngqo kumaziko omatshini akwi-axis emihlanu-akukho zixhobo zomntu wesithathu, akukho kuphinda kusetyenziswe kwiidatum ezingalungelelanisiweyo. Sibamba ii-callouts ze-GD&T njenge-±0.025 mm yokunyamezela indawo kwi-12-mm-diameter yokubeka izikhonkwane *emva* konyango lobushushu lokugqibela—hayi nje emva kokurhabaxa. Oku akuyothiyori. Kwiprojekthi yamva nje yendawo yeoli yaseMntla Melika, ukuhamba kwethu okudityanisiweyo kunciphise ixesha lokukhokela nge-37% xa kuthelekiswa nomthengisi wangaphambili osebenzisa abathengisi abahlukeneyo kunye noomatshini.
I-Cobalt-Nickel Alloys Ifuna Ngakumbi Kunokumelana Nobushushu—Bafuna Indlela Yokuziphatha
I-AMS 5387 ingxubevange ye-cobalt "ayinzima kumatshini." Ayikuxoleli ukungcangcazela, ukushukuma kwe-thermal, okanye ubomi besixhobo obungahambelaniyo. Silinganise izinga lokunxiba kwezixhobo zokutsiba i-220% xa i-pH epholileyo isihla ngaphantsi kwe-8.7 ngexesha lokusila ingxubevange ye-T800. Yiyo loo nto indawo yethu ibeka iliso kwikhemistri epholileyo ngexesha lokwenyani-kwaye iyibuyisele ngokuzenzekelayo phambi kokuba ukutenxa kufikelele kwimida. Okubaluleke ngakumbi, asiziphathi iialloys ze-cobalt "njengenye nje into." Ibhetshi nganye ye-T800 iqala ngeengxelo zovavanyo oluqinisekisiweyo lwelitye lokusila, ukulandeleka okupheleleyo kwinani lokunyibilika, kunye novavanyo lwe-ultrasonic pre-machining yokungaqhubeki komphezulu ongaphantsi komhlaba. Xa i-OEM yepompo yaseYurophu idinga iindibano ezingama-42 ezifanayo ze-cobalt-nozzle kunye ne-≤0.015 mm ukugxila phakathi kokungena kunye nokuphuma, siphumelele i-99.6% yesivuno sokuqala-kungekhona ngokongeza amanyathelo okuhlola, kodwa ngokutshixa ukuphosa imbuyekezo ye-shrinkage kwipatheni yethu yotyalo-mali kwisixhobo kunye nokusebenzisa i-laser-adaptive castings ye-CNC.
Umgangatho awuhlolisiswanga-Uyinjineli, inyathelo ngenyathelo
"Ukulandelelwa ngokupheleleyo" kuthetha into ekhonkrithi apha: yonke i-piston pump cylinder housing iphethe ikhowudi ye-QR edibanisa nesatifikethi sayo se-raw, i-X-ray yokukhupha ingxelo, idatha ye-CMM yokuskena kwizigaba ezintathu zenkqubo, kunye nelogi yovavanyo lokugqibela olusebenzayo-kuquka ukuqinisekiswa koxinzelelo olugqabhukileyo kwi-1.5 × ukulinganisa uxinzelelo lokusebenza. Asilindi ukuhlolwa kokugqibela ukuze sibambe imiba. Ukuphoswa kwentsimbi engenayo kuhlalutya i-spectral ye-chromium eshiyekileyo kunye ne-molybdenum; iitshekhi ezingaphakathi kwinkqubo zisebenzisa izithelekisi ze-optical for edge radius consistency kwizihlalo zevalvu yoxinzelelo; uhlolo olubonakalayo lokugqibela lulandela imigangatho ye-ASTM E2877-22 yokuhlelwa kwesiphene somphezulu. Kwikota yokugqibela, oku kubambe ibhetshi yentsimbi engenasici apho umxholo wesulfure ukhukuliseke nge-0.003% ngaphezulu kwe-spec-engabonakali kwiliso lenyama kodwa ibonakaliswe ukukhawulezisa i-galling kwiindawo zokutywinwa eziguqukayo. Akukho nxalenye yeenqanawa ngaphandle kobungqina obubhaliweyo kwisango ngalinye.
Ukuthembeka kwehlabathi lokwenyani kuqala ngoPhononongo lobuNjineli obuyinyani
Abanye ababoneleli bayayamkela imizobo kunye namaxesha okucaphula. Siqala ngemibuzo: "Ingaba i-0.05 mm ye-flange callout iyafuneka kwi-flange yonke ekhwelayo-okanye kuphela kwisangqa sebholiti?" Ngaba umthengi ufuna ubulukhuni be-AMS 5737 *emva komatshini wokugqibela, okanye ngaba ubunzima basemva kobushushu bokwaneleyo? Ukulungelelaniswa kwangethuba kuthintela uhlengahlengiso olunexabiso eliphezulu. Kumzantsi-mpuma we-Asia yobunjineli be-winch shaft oda, iqela lethu liye lachaza ukuba umzobo wokuqala uchaze i-HRC 58-62 kwicandelo le-120-mm-diameter-engenakufezekiswa ngaphandle kokuqhekeka kwi-alloy ekhethiweyo ye-42CrMo4. Sicebise indawo yokwenziwa lukhuni kwendawo endaweni yoko, sihlangabezane neemfuno zokusebenza ngelixa sicutha ixesha lomjikelo ngama-28%. Yiloo ndlela iprototype-to-production transitions ehlala isendleleni: ngencoko yababini yobugcisa, hayi ukucinga.
Ukuba icandelo lakho elilandelayo lesinyithi elichanekileyo lifuna ukungqinelana okuqinisekisiweyo kwesinyithi, i-sub-0.03 mm dimensional repeatability kwiicontours ezintsonkothileyo, okanye ukuphathwa okuqinisekisiweyo kwee-cobalt-nickel superalloys, yinyani. metal casting Foundry factory kufuneka wenze okungaphezulu kunokugalela nokugqiba. Kufuneka injineli yokuqiniseka-kwizinto eziphathekayo, iinkqubo, kunye nentsebenziswano. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha loo ngqiniseko kuyo yonke ivalve yoxinzelelo, indlu yesilinda, kunye nomlomo we-cobalt alloy. Isiphumo asikho nje iinxalenye ezifanelekileyo-ziinkqubo ezisebenzayo, ngokuthembekileyo, iminyaka.
