Xa iinjineli zichaza a inqanaba lomzi-mveliso, abagcini nje ngokuyalela isinyithi-babethe inkqubo yokubheja, ingqibelelo yoxinzelelo, kunye nobomi benkonzo kwi-dimensional stability phantsi kwebhayisikili ye-thermal kunye nomthwalo we-abrasive. Siye sabona iiprojekthi ezininzi zivaliwe ngenxa yokuba icandelo "eliqhelekileyo" leleveli lijike emva kweeyure ze-200 zomsebenzi we-hydraulic-okanye ukusilela ukuvavanywa kokuvuza ngenxa ye-micro-porosity kwisiseko sokuphosa. Kungenxa yoko le nto ukuchaneka akulona igama lokuthengisa apha. Ngumahluko phakathi kwendlu yempompo ephethe i-4,500 psi kwi-120 ° C okanye i-crack ngexesha lokugunyaziswa.
Kutheni uKhetho lweMpahla luyalela ukuba kusebenze iNqanaba—Hayi nje ngoMatshini
Uninzi lwamacandelo e-level asebenza njenge-ankile zesakhiwo kwiindibano ezijikelezayo: i-winch center shaft rollers, izindlu ze-cylinder, iziseko zempompo. Umsebenzi wabo kukugcina ulungelelwaniso ngelixa ufunxa i-vibration, i-torsion, kunye noxinzelelo lwe-cyclic. Kodwa ukuba imathiriyeli yesiseko ayinazinzo lwe-thermal okanye ukufana okuziinkozo, nokuthotyelwa ngokugqibeleleyo kwe-GD&T akuyi kuthintela ukukhukuliseka. Kulapho i-cobalt-nickel alloys efana ne-AMS 5387 kunye ne-T800 itshintsha umdlalo.
Sivavanye ii-alloy ezahlukeneyo ezili-12 kwiindawo ezingama-37 zokusasazwa kwehlabathi lokwenyani. I-AMS 5387 ihambisa ubulukhuni obungaguqukiyo (38–42 HRC) emva kokufakwa kwesisombululo-kwaye ngokubalulekileyo, igcina> i-92% yobo bunzima emva kweeyure ze-1,000 kwi-650 ° C. I-T800 yongeza i-chromium carbide dispersion yokumelana nokunxiba kwi-oyile egcwele isanti kunye nokusetyenziswa kwegesi. Kwiprojekthi enye yoLwandle lwaseNyakatho, imilomo ye-T800 ikhuphe i-Inconel 718 iqabane nge-3.2 × kuvavanyo lokukhukuliseka kodaka. Ukubanjwa? Ezi alloys zifuna izixhobo ezikhethekileyo, igalelo lobushushu elilawulwayo, kunye noxinzelelo lwasemva komatshini. Ayizizo zonke iivenkile ezinokubamba i-± 0.015 mm kwiplagi ye-cobalt eyi-320 mm ngaphandle kokuphazamiseka. Abambalwa basaqinisekisa ubume be-microstructure nge-ASTM E112 yohlalutyo lobungakanani beenkozo ngebhetshi nganye.
Ukudityaniswa okuthe nkqo kuSombulula iNgxaki "yeBhokisi emnyama" kwiNqanaba loMveliso
Abanye abathengi bakhupha ii-casts ezivela kwi-Foundry A, bazimatshini kwi-Shop B, kwaye bagqibe kwi-Coating C. I-handoff nganye ibeka umngcipheko wokungahambi kakuhle, unyango lobushushu olungabhalwanga, okanye ukulungiswa komphezulu okungahambelaniyo. Siqhuba ukuphosa, i-CNC, kwaye sigqibezela phantsi kophahla olulodwa oluthobelayo lwe-ISO-kuba iindawo ezisemgangathweni zisilela rhoqo kwiindawo zokujongana, kungekhona kumaziko.
Inkqubo yethu iqala ngokulandelelwa kwemathiriyeli ekrwada eqinisekisiweyo: yonke i-cobalt ingot ithwala iingxelo zovavanyo lokusila ezihambelana nenombolo yobushushu ukuya kwi-ID yokugqibela. Utyalo-mali luphethe iikhontolo zangaphakathi ezintsonkothileyo; ukugalela isanti kwakha ukuqina kwiziseko zempompo ezinkulu. Ke ii-multi-axis machining cut cut features like the concentric bores, radial cooling slots, and press-fit-fit shoulders-zonke zingqinisisiwe phakathi kwenkqubo zisebenzisa iZeiss CMMs ezilinganiswe kwi-ISO 10360-2. Akukho "uhlolo lokugqibela kuphela." Akukho ngqikelelo. Ukuba indlu yempompo yepiston ibonisa i-0.008 mm ukutenxa kubuso be-flange emva koburhabaxa, siphinda silandelelanisa amandla okubamba kunye nokunxitywa kwesigxina-ungalindi kude kube yi-QC yokugqibela.
Oku kudityaniswa kwenza izisombululo zemixube. Omnye umxumi wase-Asia-mpuma ufuna ipleyiti ekwaziyo ukumelana nomhlwa enezigubu ezifakelweyo ezidibeneyo kunye nemijelo yolwelo. Esikhundleni sokudibanisa iindawo ezihlukeneyo, siphosa isiseko kwi-ductile iron (ASTM A), emva koko i-CNC-machined seal surfaces kunye neendlela zokuhamba ngokuseta enye-ukuphelisa i-4 weld joints, i-7 NDT iitshekhi, kunye neeveki ezi-3 zexesha lokukhokela.
Ukuhanjiswa kweNtembeko yokwenyani iqala kwakudala ngaphambi kweleyibhile yokuThumela
"Ukuhanjiswa ngexesha" akuthethi nto ukuba ukuthunyelwa kokuqala kufika kunye ne-15% ye-scrap ngenxa ye-porosity engabonakaliyo okanye ubunzima obungafaniyo. Sinyanzelisa ii-checkpoints ezintathu ezingenakuxoxisana: ukuqinisekiswa kwezinto ezingenayo (i-spectrometry + i-tensile sampling), i-in-process dimensional and metallurgical audit (yonke inxalenye ye-25), kunye nokuqinisekiswa okugcweleyo okusebenzayo-uvavanyo loxinzelelo ukuya kwi-6,000 psi, ukulinganisa okuguquguqukayo kwezinto ezijikelezayo, kunye ne-salty-spray exposure yokugqitywa kwe-stainless stain.
Ngee-odolo zeprototype, iqela lethu lobunjineli liqhuba uphononongo lokwenziwa kwezinto ngaphakathi kweeyure ezingama-48-hayi ukujonga nje ukunyamezelana, kodwa ukuhlaba umkhosi kwi-GD&T ebangela ukuphazamiseka okanye ukungacaci komlinganiselo. Sakhe sabamba ukunyamezelana kwe-±0.005 mm kumngxuma ongaboniyo ofuna ukufikelela okungenakwenzeka. Ukuyila ngokutsha iskimu sedatum kugcine umthengi i-24,000 yeedola kwizixhobo ezilahliweyo kunye neeveki ezili-11 zokulibaziseka.
Abathengi behlabathi-ukusuka kwii-OEMs eJamani ukuya kwi-Tier-1 ababoneleli eTexas-bathembele kolu qeqesho. Ukuhamba kwethu okuthambileyo kulandelela i-WIP ngexabiso lomjelo, hayi isebe. Ukuba indawo ye-cobalt alloy leveler ibetha ibhotile kunyango lobushushu, ulawulo lwemveliso luhlengahlengisa ulandelelwano lomatshini *phambi* kweefom ze-backlog-hayi emva koko.
ICandelo loMzimveliso weNqanaba lithetha iNtsebenziswano yobuNjineli, hayi iMveliso nje
Yinyani inqanaba lomzi-mveliso ayiyeki kwiibhokisi zokuthumela. Ilindele iindlela zokungaphumeleli: ukungafani kokwanda kwe-thermal phakathi kwendlu yentsimbi kunye nesitulo sevalve ye-cobalt, ukunxitywa kwe-roller-shaft interfaces, ukugabha ngexesha le-torque yokuhlanganisa. Yingakho inkxaso yethu ibandakanya ukuqinisekiswa komzobo, isikhokelo sokutshintshwa kwezinto (umzekelo, xa unikezelo lwe-AMS 5387 luqinisa), kunye nohlalutyo oludibeneyo lwengcambu xa ukusilela kwintsimi kwenzeka.
Ukujonga phambili, sizama ukwenza nzulu i-R&D kwiinkqubo ezixutyiweyo zokwenziwa komatshini-ngokukodwa, utyalo-mali olukufutshane ne-net-shape yezixhobo ze-cobalt ezinomgangatho owenziwe ngoomatshini obanjwe kwi-Ra 0.4 µm. Ukwandiswa kwesatifikethi kubandakanya i-AS9100 ye-aerospace-critical levelers kunye ne-API Q1 yezicelo ze-subsea.
Ukuba izinto zakho zeleveli kufuneka ziphile kuxinzelelo oluphezulu, ukunxiba okuphezulu, ubushushu obuphezulu-kwaye ufuna ukungaqondakali kwento kumnombo wezinto eziphathekayo, ukuphindaphindwa komgangatho, okanye ukuhanjiswa ngokuqinisekileyo-ke ubunzulu bobugcisa, ulawulo oluthe nkqo, kunye noqeqesho olubhaliweyo alukhethi. Basisiseko. Lowo ngumgangatho owakhelwe kuyo yonke indawo ukusuka kwiQingdao Qiangsenyuan Technology Co., Ltd.
