Xa iinjineli zicacisa iinxalenye ze-AMS 5387 zeStellite kwiimpompo ze-hydraulic, iivalve ezinoxinzelelo oluphezulu, okanye iinkqubo ze-winch zaselwandle, azikhethi nje izinto eziphathekayo-zikhetha isiqinisekiso sokusebenza. I-AMS 5387 esekwe kwi-Cobalt inikezela ukuxhathisa okukhethekileyo kwi-galling, abrasion, kunye nokuthotywa kwe-thermal apho iintsimbi eziqhelekileyo zisilela. Kodwa i-specs zemathiriyeli ekrwada zithetha kancinci ngaphandle kokwenziwa ngokuchanekileyo. Yiyo loo nto ukukhangela kwi- I-AMS 5387 yenxalenye yomzi-mveliso weStellite ngolawulo oluqinisekisiweyo lwe-metallurgical, i-GD & T eqinile, kunye nokulandelwa kwenkqubo ebhaliweyo ayikhethi-ibaluleke kakhulu.
Kutheni i-AMS 5387 ifuna ngaphezulu kokuphosa nje okanye ukwenza uMatshini
Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype kuba ababoneleli baphatha i-AMS 5387 njengenye ialloy. Ayiyo. Ubume bayo obuphezulu be-cobalt-nickel-chromium-molybdenum buyenza ibenzima kakhulu, isebenze nzima ngexesha lomatshini kwaye inovelwano kumothuko wobushushu ngexesha lonyango lobushushu. Ukupasa okukodwa kunye nejiyometri yesixhobo esingalunganga kunokubangela ukuqhekeka kancinci. Umjikelo wokupholisa ngokukhawuleza emva kwesisombululo se-annealing unokutshintsha ukusabalalisa i-carbide-ubomi bokugqoka obungcolileyo ukuya kuthi ga kwi-40% ekuvavanyeni intsimi. Kulingo lwethu lwemveliso, siye safumanisa ukuba iinxalenye ze-AMS 5387 ezifakwe koomatshini ezinxityiweyo zibonise i-22% uburhabaxa obuphezulu bomphezulu (Ra> 1.6 µm) xa kuthelekiswa nezo zigqityiweyo kwizixhobo ezilinganisiweyo, ezinencam yePCD-kwaye loo mahluko unxibelelene ngokuthe ngqo nokuvuza kwetywina kwangaphambi kwexesha kwizindlu zempompo yepiston.
Yiyo loo nto ukudibanisa ngokuthe nkqo kubalulekile. An I-AMS 5387 yenxalenye yomzi-mveliso weStellite kufuneka ilawule ikhonkco elipheleleyo: i-T800-grade certified billet sourcing, utyalo-mali olunamazinga okuqinisa alawulwayo, ukukhulula uxinzelelo ngaphambi komatshini onzima, i-CNC ye-multi-axis enembuyekezo ye-real-time tool, kunye ne-HIP yokugqibela (i-hot isostatic pressing) xa ifuneka. Akukho handoffs. Akukho kuguquguquka kwe-batch-to-batch kubulukhuni (HRC 38-45) okanye i-carbide dispersion.
Izakhono ezine ezingaxoxisiyo kufuneka uziqinisekise
Ngaphambi kokuba ukhuphe imizobo, buza umthengisi wakho le mibuzo mine-kwaye ufune ubungqina:
- Ngaba uqinisekisa iibhilethi ze-AMS 5387 ezingenayo kunye ne-PMI epheleleyo + uhlalutyo lwe-spectrographic? Siyala i-3.7% yamaqashiso angenayo ngokusekwe kuphambuko oluncinci lwe-Mo / Cr-nangaphakathi kwimida ye-ASTM-kuba ichaphazela ukubunjwa kwesigaba sesibini phantsi komthwalo we-cyclic.
- Ngaba unokubamba i-±0.015 mm kwiidayamitha zokutywina ezibalulekileyo kwizindlu zecylinder ezingama-320 mm? Ikhono lethu eliqinisekisiweyo le-CMM kwi-cobalt alloys yi-± 0.012 mm-hayi "ukuya kuthi ga" kodwa ifunyenwe ngokuqhubekayo kwiindawo ze-serial ze-50 +.
- Ngaba wenza uhlolo lwe-ultrasonic post-machining kuwo onke amacandelo anoxinzelelo? Ewe-kwaye sigcina iirekhodi ezipheleleyo zokuskena zedijithali ezibotshelelwe kwiqashiso lobushushu kunye ne-ID yomsebenzisi.
- Ngaba unokuphinda uphindaphinde ulwakhiwo lwe-microstructure kwiindawo ezisetyenzisiweyo? Ewe, nge-laser cladding yendawo usebenzisa i-AMS 5387 powder kunye nekhemistri ehambelanayo, ilandelwa yi-HIP kunye nokugqiba imishini.
Apho ababoneleli abaMgangatho besilela khona-kwaye yintoni esebenzayo endaweni yoko
Abanye abavelisi bakhupha oomatshini be-AMS 5387 kwiivenkile zemisebenzi ngokubanzi. Sakhe sazama ukuba. Isiphumo? Iibhetshi ezintathu ezikhatywayo ngenxa yamanqaku okuxoxa angaphantsi komhlaba angabonakaliyo ekuhlolweni kwe-optical-kodwa zifunyenwe kuphela emva kweeyure ezingama-200 zovavanyo olukhawulezayo lokunxiba. Isizathu esisisiseko: ukungonelanga kokuqina kwi-3-axis mills kunye nokungabikho kwe-cobalt-specific cutting parameter databases.
Ukulungiswa kwakungengoomatshini abangakumbi-yayiyinkqubo enzulu yoqeqesho. Ngoku sisebenzisa amaziko omatshini wegranite aqinile, azinzileyo ngokwe-25-axis anolawulo oluhlanganisiweyo lobushushu obupholileyo (± 0.5°C), ukulinganisa kwendlela yesixhobo ebonisa umthwalo wetshiphu ngezinyo ngalinye *phambi* kokusikwa, kunye nenkqubo yokuqinisekisa i-touch-probe emva kokudlula ngakunye. Kwiijometri ezintsonkothileyo ezifana ne-cobalt alloy nozzles kunye neeprofayili ze-convergent-divergent zangaphakathi, sidibanisa ukufakwa kotyalo-mali kwimilo ekufutshane nenetha kunye ne-electrochemical machining (ECM) ye-contour yokugqibela-ukuphelisa uxinzelelo lomatshini ngokupheleleyo.
Ukusebenza kwehlabathi lokwenyani: Ukusuka kuMzobo ukuya kuSaziso lweNdawo
Omnye umthengi wayefuna ii-AMS 5387 zeshaft rollers ukwenzela iiwintshi zemoto yobunjineli ekude nonxweme—kuxhomekeke kuntywiliselo lwamanzi etyuwa, imithwalo ye-radial eyi-120 kN, kunye nemijikelo yokuyeka ukuqalisa rhoqo. Umboneleli wabo wangaphambili uhambise iirola ezihlala iiyure ezingama-4,200 zokusebenza ngaphambi kokuba kuqaliswe umgodi. Inguqulelo yethu, ngolungelelwaniso lwenethiwekhi ye-carbide ephuculweyo kunye ne-Ra ≤ 0.4 µm yokugqiba umhlaba, idlule iiyure ze-11,800 kwinkonzo efanayo-phantse kathathu ubomi. Akukho ukuyilwa ngokutsha. Akukho kuphuculwa kwezinto. Ukulawula nje okungqongqo kwinto eyenzekayo phakathi kwesithando somlilo kunye nesikhululo sokugqibela se-QC.
Eso siphumo sibonisa indlela a I-AMS 5387 yenxalenye yomzi-mveliso weStellite isebenza: hayi njengomthengisi, kodwa njengokwandiswa kweqela lakho lobunjineli. Siphinde sihlolisise ii-callouts ze-GD & T kwangethuba, iiflegi ezinokuthi zibe nobungozi bomatshini kwi-radio engekho-standard okanye amacandelo amancinci, kwaye sinikeze amaxwebhu apheleleyo e-PPAP-kuquka iitshathi zokuphatha ukushisa, iingxelo ze-CMM, kunye neefoto ze-microstructure-ngaphambi kokuvunywa kwenqaku lokuqala.
Ingcamango yokugqibela: Ukuchaneka akulinganiswa kwiiMicrons zodwa
Ukusebenza okwenene kumacandelo e-AMS 5387 avela kwi-consistency-kungekhona nje kwi-dimension, kodwa kwi-microstructure, iprofayili yoxinzelelo olushiyekileyo, kunye nokunyaniseka komphezulu. Oko kufuna uhlengahlengiso lwemihla ngemihla lwenyathelo ngalinye lenkqubo, hayi nje uphicotho lonyaka. Kuthetha ukugatya ininzi yokushisa phezu kwe-0.03% ye-carbon deviation-kungekhona ngenxa yokuba i-spec ivumela, kodwa ngenxa yokuba idatha yentsimi ibonisa ukuba ikhawuleza ukunxiba kwe-abrasive kwiindawo ezinodaka.
Ukuba iprojekthi yakho elandelayo ixhomekeke kwiinxalenye ze-AMS 5387 zeStellite, jonga ngaphaya kweziqinisekiso. Buza iitshathi zokubaleka zokwenyani. Cela iisampulu zeengxelo zovavanyo kwiiodolo zakutsha nje kwicandelo lakho. Qinisekisa ukuba baphosa *kunye* nomatshini we-cobalt alloys-hayi nje ukuphatha. Ngenxa yokuba kwi-high-wear, ukuthembeka okuphezulu kwezicelo, umahluko phakathi "kwemisebenzi" kwaye "awuyi kusilela iminyaka emi-5" uhlala kwiinkcukacha akukho luhlu lwedatha.
