Xa iinjineli zichaza iibheringi zeStellite, azikhethi nje izinto eziphathekayo-zibophelela ekunyamezeleni ukunxiba, ukubola, okanye ukukhukuliseka phantsi koxinzelelo olukhulu. Eso sigqibo sihlala ngokulinganayo kumgangatho wefektri: ayizizo zonke iziseko okanye ivenkile ye-CNC enokuvelisa ngokuthembekileyo izinto zeStellite ezihlangabezana ne-AMS 5387, ASTM F1537, okanye i-ISO 4967 iimfuno-ingakumbi xa iijiyometri zifuna ulawulo oluluqilima lwe-GD&T, umphezulu ugqiba phantsi kwe-Ra 0.4 µm, kunye ne-microstructural consistency yonke. Sibone iiprojekthi ezininzi kakhulu zimile ekuqinisekiseni iprototype ngenxa yokuba Umzi mveliso weStellite bengenabuchule obudibeneyo bokuphosa-okanye okubi ngakumbi, endaweni yamabanga e-cobalt alloy ngaphandle kokulandeleka kwe-metallurgical.
Kutheni ii-Stellite Bearings zisilela ngaphambi kokuba zifake (kunye nendlela yokuyinqanda)
I-Stellite ayenziwanga njengentsimbi engatyiwayo. Ukuqina kwayo (i-45-65 HRC njenge-cast, ukuya kuthi ga kwi-70 HRC emva kokuqina), inethiwekhi ye-carbide e-abrasive, kunye ne-thermal conductivity ephantsi ifuna izixhobo ezikhethekileyo, ukulungiswa okuqinileyo, kunye nokutya / isantya separameters ezilinganisiweyo ngeqashiso-kungekhona kwikhathalogu nganye. Kwinkqubo enye yokwakhiwa kwempompo ye-hydraulic, i-Tier-1 OEM yalile i-37% yabathwali beringi ye-Stellite piston engenayo. Unobangela weengcambu? Umthengisi usebenzise isitokhwe se-cobalt-nickel eqhelekileyo endaweni yezinto eziqinisekisiweyo ze-AMS 5387-kwaye weqa ukukhululeka koxinzelelo lwasemva komatshini. Isiphumo: micro-cracking phantsi kwe-3,000 psi cyclic ukulayisha kwiiyure ezingama-48 zokuvavanywa kwebhentshi.
Impumelelo yelizwe lokwenyani iqala kwangethuba-ekufuneni izinto kunye nenkqubo yokwenza imaphu. A ufanelekile Umzi mveliso weStellite kufuneka iqinisekise izatifikethi zebillet ekrwada (MTRs) phambi kokuphosa, lawula umoya we-oven ngexesha lotyalo-mali ukukhusela i-carbon pickup, kunye nokuqinisekisa imijikelo yonyango lobushushu kunye neeprofayili zexesha elithile lobushushu bebhetshi. Akukho ndlela zimfutshane. Akukho zixhobo "ezilungileyo ngokwaneleyo".
Izakhono ezine eziNgaxoxisaniyo kwiFactory yeNqanaba yeStellite
Sivavanya ababoneleli ngokuchasene nezi mpawu zine zokusebenza-kuba bamisela ngokuthe ngqo ukuba icandelo lakho liyasinda kwinkonzo yasentsimini okanye liyasilela ngexesha le-FAT:
- Ukulandelelwa kweMathiriyeli ukuya kwiBatch yeNyibilika: Yonke inxalenye yeStellite kufuneka iphathe amaxwebhu apheleleyo ogcino-ukusuka kwisatifikethi sokusila ukuya kutsho kwingxelo yokugqibela yokuhlolwa—enenombolo yobushushu egximfizwe okanye ephawulwe ngelaser kwicandelo ngokwalo.
- Ukuphosa-Machining Integration: Umphezulu weStellite as-cast is brittle. Ukuyisusa ngomatshini ngaphandle kokwenza umonakalo ongaphantsi komhlaba kufuna ulawulo oluchanekileyo lokusikwa kunye nokuhanjiswa kwesipholisi okulungiselelwe ialloys yecobalt-hayi ialuminiyam eqhelekileyo okanye iinkqubo zentsimbi.
- UHlolo oluqhutywa yi-GD&T, hayi nje iitshekhi zoMda: Ukunyamezela kwe-0.02 mm ububanzi kuthetha nto ukuba isikhundla, ukuphuma, okanye ukunyamezela kweprofayili akuqinisekiswanga ngokusebenzisa ii-CMM ezilinganisiweyo kunye ne-ISO 10360-2 i-probes eqinisekisiweyo-kwaye ihambelana ne-interfaces yendibano esebenzayo.
- uQinisekiso lweMfezeko yoMphezulu: Ngaphaya kwe-Ra, sifuna uhlalutyo lwe-SEM enqamlezileyo malunga ne-microcracks ekufutshane nomphezulu kunye nemephu yoxinzelelo olushiyekileyo nge-XRD kwiindawo ezibalulekileyo ezijikelezayo njenge-winch center shaft rollers okanye i-pump cylinder housings.
Ngaphandle kwezine, uthenga iinxalenye-hayi isiqinisekiso sokusebenza.
Apho Ukuchaneka Kudibana Nenyani Yesicelo
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sakha amacandelo e-Stellite apho ukungaphumeleli kungeyondlela yokukhetha: AMS 5387 cobalt alloy 6 pump housings rated for 5,000 psi operation okuqhubekayo; Imilomo esekelwe kwi-T800 ephethe i-slurry e-abrasive kwi-120 ° C; iirola zeshaft ezingezizo ezisemgangathweni kwiziko leefestile zemoto yobunjineli ekude nonxweme ezisebenza kwindawo enetyuwa egcweleyo, eshukuma kakhulu. Ezi ayizozinto eziphuma kwishelufu. Uyilo ngalunye lujongana nokuphononongwa kwe-manufacturability-kungekhona nje ngeendleko, kodwa kumngcipheko wokuphazamiseka kwe-thermal ngexesha lomatshini, iindawo zokwahlulwa kwe-carbide kumacandelo okuphoswa, kunye nokulandelelana kokugqiba ukugcina uxinzelelo olucinezelayo.
Asenzi "inxalenye yeStellite." Iinjineli zinxiba ukuxhathisa kwijometri, imathiriyeli, kunye nenkqubo-emva koko singqina ngedatha: iingxelo zovavanyo lwe-ASTM E8 nganye, iimephu zobunzima kuzo zonke iindawo ezibalulekileyo, kunye novavanyo lomthwalo osebenzayo kumjikelo ngamnye ochaziweyo womthengi. Yiloo ndlela a Umzi mveliso weStellite ufumana iiodolo eziphindaphindiweyo-hayi amabango okuthengisa.
Ukukhetha iqabane lakho: Jonga ngasemva kwePhepha le-alloy
Buza le mibuzo mithathu phambi kokuba ugqibezele umthengisi:
- Ngaba ziyakwazi ukunika ii-MTR *zobushushu* obusetyenziswa kwi-odolo yakho—hayi ishidi lengxubevange eqhelekileyo?
- Ngaba bayayenza inkqubo yokuqinisekisa ubulukhuni *emva* komatshini wokugqibela kunye *phambi kokugqiba* kwaye bagcine ezo rekhodi?
- Ngaba baya kubelana ngesicwangciso sabo sokuhlola i-GD & T-kubandakanywa nesakhiwo se-datum, ukulandelelana komlinganiselo, kunye nesimo sokulinganisa izixhobo-ngaphambi kokusika isinyithi?
Ukuba impendulo ngu "hayi," "hayi umgangatho," okanye "siya kuqinisekisa kamva," hamba. I-Stellite ayikho malunga nempahla yodwa-imalunga nokubulawa okulawulwayo ukusuka kwi-melt ukuya kwi-metrology. Ilungelo Umzi mveliso weStellite ayihambisi nje iinxalenye. Inika uqikelelo.
