Akatswiri akamatchula magawo a mapampu a hydraulic, mavavu akumunda wamafuta, kapena makina owinda olemera kwambiri, "fakitale yamakampani opanga makina apamwamba kwambiri" singosaka chabe - ndizofunikira zomwe sizingakambirane. Kukhazikika kwazithunzi pansi pa kulolerana kwa 50 µm. Microstructure umphumphu pambuyo kutentha kutentha. Kumapeto kwa pamwamba komwe kumakana kuphulika munjira zamadzimadzi zothamanga kwambiri. Izi si zizindikiro zongoyerekeza. Ndizomwe zimapangitsa kuti pampu ya piston ikhale 3,000 psi kwa miyezi 18 popanda kutayikira-ndi zomwe zimalekanitsa ma prototypes ogwira ntchito kuchokera kuzinthu zotsimikiziridwa ndi munda.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwiritsa ntchito fakitale yamakampani opanga makina olondola kwambiri pomwe ma aloyi a faifi ya cobalt samangodulidwa - amamvetsetsa *. Tawona makasitomala akutumiza AMS 5387 cobalt alloy 6 pump housings kubwerera kawiri: choyamba ndi ming'alu yaying'ono pafupi ndi mapepala otenthedwa ndi kutentha, kenaka ndi GD & T callouts kutanthauziridwa molakwika ngati mayiko awiri m'malo mwa unilateral. Zolephera zonse ziwirizi zidachokera ku mbiri yosagwirizana ndi kutentha, osati zida. Ichi ndichifukwa chake malo athu amaphatikiza kuponyera, ma CNC amitundu yambiri, komanso kutentha kwapambuyo makina pansi padenga limodzi. Palibe ma handoffs. Palibe batch-to-batch drift mu kapangidwe ka tirigu. Kungotsatiridwa, kubwerezedwa, kuwongolera ndondomeko yolembedwa.
Kuthekera zinayi kumatanthawuza kulondola kwenikweni kwapadziko lapansi-osati masamba owerengeka okha:
- Cobalt-nickel mastery kupitilira ma datasheet: T800 cobalt-based material si makina ngati zitsulo zosapanga dzimbiri. Mlingo wake woumitsa ntchito umakwera pambuyo pa 0.1 mm wakuzama wodulidwa. Timagwiritsa ntchito ma geometri a zida za PCD, kutumiza koziziritsa kukhosi, komanso kuyang'anira katundu wa spindle munthawi yeniyeni-osati chifukwa ndi yonyezimira, koma chifukwa tinayeza moyo wautali wa zida za 42% pamilomo ya cobalt alloy pomwe mitengo yazakudya imatsika 15% pakudutsa komaliza kwa 0.05 mm.
- Kuphatikizika koyima komwe kumalepheretsa kusuntha kwa dimensional: Maziko a pampu yachitsulo choponyera mchenga nthawi zambiri amapindika panthawi yochepetsera nkhawa. Ngati Machining kumachitika masabata kenako subcontractor, inu kutaya matenthedwe kukumbukira kuponyera. Makina athu apakatikati pasanathe maola 72 akuchiza kutentha-kuyesa kupotoza ndi Zeiss CMM isanachitike ndi pambuyo pake, kukonza kukonza munthawi yeniyeni. Zotsatira zake: zibowo za silinda zimasunga ± 0.015 mm kuzungulira kutalika kwa 300 mm, ngakhale pakupanga 45-kg.
- Kumaliza kogwira ntchito-osati zodzikongoletsera: Mpando wa valve wopanikizika si wa Ra 0.4 µm. Ndi za kulimba kwa mapiri komwe kumapangitsa 45% kukhala ndi 0.8 µm core roughness, kotero kulumikizana kwa milomo yosindikiza kumagawa katundu mofanana. Timatsimikizira kumaliza kulikonse ndi profilometry ndi ma epoxy replicas ophatikizika-osati kungoyang'ana kowoneka. Makasitomala omwe asintha kuchokera ku ogulitsa amtundu wa "smooth finish" adanenanso kuti moyo wautali wautumiki wa 3.2 × pamisonkhano yamapampu akunyanja.
- GD&T ngati zokambirana zaukadaulo-osati kumasulira: Pamene kasitomala alemba "Ø25.000 +0.005/-0.000" pa chodzigudubuza chapakati, sitiganizira zapakati pa ISO 2768. Timafunsa kuti: Kodi izi ndi zosokoneza zofalitsa? Za dynamic balance? Kwa chilolezo chokulitsa kutentha? Kenako timayika datum iliyonse kumalo enieni, kutsanzira kupotoza kwa NX, ndikubwezeretsanso zojambula - osati "zovomerezeka." Umu ndi momwe tidagwirizira chandamale cholakwika pamakina opangira makina opangira makina omwe akadapangitsa kuti 0.12 mm atuluke mwachangu.
Ena amatsutsa kuti maunyolo ogulitsa padziko lonse lapansi amapangitsa kuti kulondola kwawoko kusakhale kwachikale. Koma yesani kupeza pulagi ya cobalt alloy yosakhazikika yokhala ndi mayendedwe ozizirira mkati, makulidwe a khoma la 0.02 mm, ndi kutsatira kwa AMS 5737 - ndiye dikirani milungu 14 kuti munyamule katundu, kuchedwa kwa kasitomu, ndi kuzunguliranso. Timapereka mapulagiwo m'masiku 22 ogwira ntchito, okhala ndi ma cert athunthu (MTRs), zipika za kutentha, ndi malipoti a CMM ophatikizidwa muzotumiza. Sanatumizidwenso imelo pambuyo pake. Osati "zikupezeka popempha." M'bokosi.
Malo athu ogwirizana ndi ISO ku Qingdao amasamalira zambiri kuposa kulolerana kolimba. Imasamalira zotsatira zake. Pamene OEM yaku Europe idafunikira ma silinda a pampu ya piston m'malo mwake gulu laopereka litalephera kuyezetsa kupopera mchere, tidayesa kuyesa kwa dzimbiri pazithandizo zitatu zapamtunda - 316L yamagetsi, HVOF-yogwiritsidwa ntchito WC-Co, ndi duplex nitrided 17-4PH-kenako kutumiza mayeso a exposure 500000. Wogula anasankha nitriding. Magawo tsopano adutsa miyezi 24 m'malo otentha kwambiri. Izo sizikupanga. Ndiko kutengerapo chiopsezo-ndi umboni.
Fakitale yamakampani opanga makina olondola kwambiri imapangitsa kuti anthu aziwakhulupirira osati polemba ziphaso, koma pothetsa mavuto omwe ena amapewa. Monga kupanga mphuno ya aloyi ya 120-mm-diameter yokhala ndi 0.3-mm-thin-thin-radial vanes-pomwe chida chikuyenera kukhala pansi pa 3 µm kapena kusintha kwa angle kwa 0.8°, kusokoneza kayendetsedwe kake. Kapena kutsimikizira kuti maere aliwonse a AMS 5387 amakumana ndi masitepe a ASTM A990 * ntchito ya CNC isanayambike-osati zidutswa zitapangidwa. Kapena akugwira ± 0.008 mamilimita kulolerana pa zoyika 16 za ulusi papampu imodzi ya aluminiyamu-pogwiritsa ntchito zomangira za vacuum zomwe zimachotsa kusuntha kwa mbali pakugogoda.
Ngati pulojekiti yanu yotsatira ikufuna kuti magawo omwe amapulumuka chifukwa chopanikizika kwambiri, ovala kwambiri, kapena ochita dzimbiri-popanda kukonzanso kapena kulephera m'munda, ayambe ndi kupanga, osati ma geometry okha. Pitani https://www.tsingtaocnc.com kuti muwunikenso ziganizo za luso laukadaulo, kutsitsa maupangiri abwino kwambiri a GD&T, kapena perekani zojambula kuti mupeze mayankho aulere pakupanga. Kulondola sikumatanthauzidwa ndi ma micrometer okha. Zimatanthauzidwa ndi zomwe zimalephera-ndi zomwe sizitero-pamene dongosololi likugwira ntchito.
