Xa iinjineli zichaza iinxalenye zeempompo zehydraulic, iivalvu zaselunxwemeni, okanye iinkqubo zewinch enzima, azifuni nje “ukuvalwa ngokwaneleyo.” Bayayidinga umzi-mveliso wamalungu omatshini achanekileyo imveliso apho ± 0.01 mm ukunyamezela akusiyo ibhonasi-yinto esisiseko. Sibone abathengi bebuyisela imijikelo emithathu yeprototypes kuba ukukhukuliseka okulinganayo kwimilomo ye-cobalt alloy kubangele ukhukuliseko lwezihlalo kwangaphambi kwexesha. Sibukele ixesha lokuhambisa lisihla xa ukuncipha kwe-shrinkage kungahlawulwanga kulungiselelo lwe-CNC. Yiyo loo nto sigxila kwinto esebenzayo-hayi iincwadana, kodwa ukuphindaphindwa kwehlabathi lokwenyani phantsi koxinzelelo, ubushushu, kunye nomthwalo womjikelo.
Ukuchaneka Kwehlabathi Lokwenyani Kuqala Kulawulo Lwezinto Ezibonakalayo-Hayi nje NgoMatshini
Iivenkile ezininzi zithatha imathiriyeli njengendawo yokuqala. Siyiphatha njengenyathelo lokuqala lenkqubo. I-cobalt-nickel alloys efana ne-AMS 5387 kunye ne-T800 ayinzima nje kumatshini-i-metallurgically sensitive. Ukutenxa nge-5°C ngexesha lesisombululo se-annealing kutshintsha ukusasazwa komda we-carbide. Olo tshintsho lunxiba ukuxhathisa kwizindlu zempompo ukuya kuthi ga kwi-37%, ngokusekwe kuvavanyo lwethu lwangaphakathi lokunxiba ngaphezulu kwemijikelo eyi-12,000. Ngoko ke sisebenzisana nomthombo weebhilithi eziqinisekisiweyo kunye nababoneleli ababonelela ngokulandeleka kobushushu obugcweleyo-ukuhla ukuya kwi-ID yebhetshi yesithando somlilo kunye nezikhuni zokupholisa-hayi nje izatifikethi zokusila. Xa umthengi esithumelele umzobo weplagi yealloyi ye-cobalt engeyiyo eyomgangatho, siye safaka iflegi yoluhlu lobunzima obuchaziweyo ngokuchasene negophe lokwenyani lamandla obo bushushu. Isiphumo? Umjikelo ohlaziyiweyo wonyango lobushushu oye wazisa i-HRC 42–44 *yaye* yagcina ukuqina kwempembelelo ngaphezu kwe-28 J ku- -20°C. Akukho kuphinda kusebenze. Akukho kulibaziseka.
Ukudityaniswa okuthe nkqo akusiyo i-Buzzword-Yindlela obamba ngayo unyamezelo kuzo zonke iinkqubo
Ukuphosa + umatshini + ukugqiba phantsi kophahla olunye kutshintsha yonke into. Qwalasela i-winch yemoto ye-winch centre shaft roller: isanti-cast in ductile iron (ASTM A536 Grade), emva koko igqitywe ngomatshini ukuya ku-±0.008 mm kumphezulu wejenali, emva koko i-induction-harded to 58–62 HRC. Ukuba loo manyathelo ayenzeka kubathengisi abathathu, ukugqwetheka kwe-thermal ekukhupheni isiqabu soxinzelelo kuyavalwa ngaphambi kokuba kuqale umatshini-kwaye ugxotha ijometri endaweni yokubamba. Kwiziko lethu laseQingdao, sisebenza ngomatshini kwiiyure ezingama-48 zokuphosa ishakeout. Sisebenzisa inkqubo yokutshekishwa kwe-CMM emva kokurhabaxa, ukugqiba ngesiqingatha, kunye nokugqiba-nganye ibotshelelwe kwi-callouts ye-GD&T, hayi nje imilinganiselo yesiqhelo. Kwizindlu zempompo yepiston, siyaqinisekisa ukuba umbhobho wepiston *phambi* kokuhonjiswa kokugqibela, hayi emva. Oko kubamba ukugqwetheka okubangelwa yimidlalo kwangethuba. Kunyaka ophelileyo, oku kubambe i-0.015 mm taper shift kwi-17% yeengxenye zokuqala-ukuthintela i-220 kg ye-scrap kunye ne-loop yeveki ezintandathu.
Umgangatho awuhlolisiswanga-Yakhelwe ngaphakathi, Inyathelo ngenyathelo
Asenzi "uhlolo lokugqibela." Senza ungqinisiso oluseqongeni. Imathiriyeli ekrwada engenayo ifumana uhlalutyo lwe-spectrographic * kunye* novavanyo lwe-ultrasonic lwe-subsurface porosity-ingakumbi ibaluleke kakhulu kwi-AMS 5387 iinxalenye zepompo ezivezwe kukutyhala ulwelo olunoxinzelelo oluphezulu. Ngexesha le-CNC, i-opharetha yokungena i-log tool inxiba i-pass nganye usebenzisa i-laser-measured offset values-kungekhona uqikelelo olusekelwe kwixesha. Emva konyango lobushushu, iqashiso ngalinye lifumana imaphu yobunzima obuncinci kumacandelo amathathu anqamlezayo. Amalungu okugqibela afumana uvavanyo olusebenzayo: iivalve zoxinzelelo zivavanywe ukuhamba-kuvavanywa kwi-1.5 × imilinganiselo yoxinzelelo; imilomo ye-cobalt alloy idlula ukulinganisa ukhukuliseko kunye ne-80-micron alumina slurry kwi-30 m / s velocity. Kwaye ewe-sigcina yonke idatha. Hayi nje iingxelo. Iifayile ze-CMM ezikrwada, iilog zemifanekiso eshushu, ubulukhuni obuprintiweyo. Ukulandeleka akukho malunga nokuthotyelwa. Kumalunga nokwazi *ngokuchanekileyo* kutheni inxalenye #W-8823 ibambe ubungqukuva obuyi-0.005 mm ngelixa i- #W-8824 ikhukuliseka i-0.012 mm-kwaye iyilungise phambi kobushushu obulandelayo.
Oku kuthetha ntoni kwiProjekthi yakho elandelayo
Ukuba isicelo sakho sifuna unyamezelo oluluqilima kwi-superalloys, iikhonto ezintsonkothileyo, okanye umsebenzi obaluleke kakhulu-ungaqali ngesicelo sekowuti. Qala ngophononongo lokwenziwa kwezinto. Thumela iphakheji yakho ye-GD&T. Siza kuphawula apho ii-engile eziyilwayo zingqubana nokuba nokwenzeka kokuphosa, apho iindonga ezibhityileyo zisengozini yokugqwetheka kunyango lobushushu, okanye apho imilinganiselo yokugqiba umphezulu ingaphezulu koko kufumanekayo ngaphandle kokugaya okwesibini. Siye sanceda abathengi baseNorth America be-oilfield banciphise ixesha lokuhamba nge-30% ngokutshintsha kwi-investment-cast-only to hybrid cast-machined designs-ukugcina amandla ngelixa ususa imisebenzi emihlanu yesibini. Kwii-OEMs ze-hydraulics zaseYurophu, siphumelele i-T800 alloy components ukuya kwi-EN 10204 3.2 isatifikethi-ngaphandle kokongeza iindleko okanye umngcipheko weshedyuli. Ukuchaneka komatshini wokusebenza komzi-mveliso awulinganiswa ngokubalwa kwe-spindle okanye indawo yomgangatho. Kulinganiselwa ukuba zingaphi izinto eziguquguqukayo ozilawulayo-kwaye zimbalwa kangakanani izinto ezothusayo ezizenzayo ukuba zihlangane. Lo ngumgangatho esiwubambeleyo. Ngalo lonke ixesha.
