Pamene mainjiniya opanga ma hydraulic system kapena ogula zida zamafuta akufufuza a Precision Investment Casting Company Factory, samangoyang'ana wogulitsa wina. Akuyang'ana kutsimikizika kwapakati pa 0.02 mm kulolerana, kukhulupirika kwa microstructural pambuyo pa chithandizo cha kutentha, ndi kusiyana kwa zero batch-to-batch mu cobalt-nickel alloys-makamaka pamene gawolo ndi nyumba ya mpope ya AMS 5387 yomwe ikugwira ntchito pa 4,000 psi.
Ndiko kumene zochitika zenizeni zimasintha chirichonse. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tapanga ma nozzles opitilira 17,000 T800 kuyambira 2019-iliyonse ikufuna kutsatiridwa kwathunthu kuchokera ku satifiketi ya billet yaiwisi mpaka lipoti lomaliza la CMM. Tawona momwe 0.003 ″ kusalumikizana bwino mu nyumba ya silinda ya piston kumapangitsa kulephera kusindikiza msanga ku Southeast Asia zitsulo zakunyanja. Tawonanso momwe kuwunikira koyambirira kwa GD&T - zida zisanayambe - zimadula nthawi yobwereza ndi 60%.
Chifukwa chiyani kuphatikiza koyima ndikofunikira kuposa momwe mukuganizira
Ogula ambiri amaganiza kuti "kuponya ndalama" ndi "CNC Machining" ndi ntchito zosiyana. Iwo sali—pamene gawolo liri lofunikira-utumwi. Thupi la valavu loponderezedwa loponyedwa muzitsulo zosapanga dzimbiri liyenera kukhalabe lokhazikika * pambuyo * kuchepetsa kupsinjika, chithandizo cha kutentha, ndi mphero ya ma axis asanu. Izi zimangogwira ntchito ngati kuponyera, kutenthetsa, ndi kupanga makina kumachitika pansi pa denga limodzi - ndi metrology yogawana, zipika zazinthu zolumikizana, ndikutsimikizira njira zofananira.
QINGDAO QIANGSENYUAN imagwira ntchito mwanjira imeneyo. Malo ake ogwirizana ndi ISO amayang'anira kuponya mchenga kwa maziko akulu a pampu, kuyika ndalama kwa mapulagi a cobalt alloy okhala ndi makulidwe a khoma mpaka 1.8 mm, ndi ma CNC amitundu yambiri amagwira ntchito pazitsulo zolimba za 17-4PH - zonse mkati mwa njira imodzi yopanga. Palibe ma handoffs. Palibe zolakwika zomasulira za data. Palibe mbiri yotayika ya kutentha kwapakati pakati pa ogulitsa.
Izi sizongoyerekeza. Pamene European OEM inkafunika mayunitsi 240 a chodzigudubuza cha winch center shaft chosakhazikika - chopangidwa kuchokera ku AMS 5387, chokhala ndi ± 0.015 mm kuzungulira pa 120 mm OD - tidapereka chivomerezo cha nkhani yoyamba m'masiku 11. Osati chifukwa tinathamangira. Chifukwa gulu lathu loyambitsa zidali lidayenereza kutsika kwa nkhungu ndi aloyi wofananira wa cobalt-nickel omwe amagwiritsidwa ntchito pomaliza - ndipo akatswiri athu adagwiritsa ntchito zomwezo kuti akhazikitse zosinthika asanayambe kudula.
Zomwe zimalephera-ndi chifukwa chiyani-pamene ma alloys a cobalt amachoka
Ogula ena amachokera kuzinthu za cobalt kuchokera kuzinthu zopangira zolinga. Amapeza zigawo zomwe zimadutsa pakuwunika-koma zimalephera kuyesa ntchito pa 350 ° C. Chifukwa chiyani? Chifukwa AMS 5387 imafuna kulamulira mwamphamvu kwa carbon (0.15-0.25%), silicon (≤1.0%), ndi boron (0.001-0.006%). Kupatuka pang'ono ngati + 0.002% boron kumachepetsa kuuma kotentha ndi 18%. Sizidzawoneka pamayeso oyambira a PMI - koma zingayambitse kukwiya pampando wopumira kwambiri.
Timapewa izi popanga zinthu zofananira ndi ogulitsa ovomerezeka-ndi kutsimikizira koyilo iliyonse yomwe ikubwera ndi ma OES spectroscopy *ndi* intergranular corrosion test pa ASTM A262 Practice E. Timasunga zolemba zonse zamagulu: nambala yosungunuka, kutentha kwa kuthira, kuzizira, masitampu anthawi yoziziritsa kutentha. Ngati kasitomala afunsa kuti ayesenso deta miyezi isanu ndi umodzi pambuyo pake? Timachikoka mkati mwa mphindi ziwiri.
Chilango chimenecho chimafikira ku geometry. Makina athu oyezera owoneka bwino amatsimikizira ma angles opangira ma turbine vanes asanachotse zipolopolo. Ma CMM athu amayendetsa ma GD&T routines—osati “cheki m'mimba mwake”—koma malo, mbiri, ndi kuthamangitsidwa kogwirizana ndi zomwe zafotokozedwa pachithunzichi. Palibe zongoganizira. Palibe zochotsa pamanja.
Kutumiza kwenikweni—popanda buffer “yongochitika zokha”
"Nthawi zotsogola zokhazikika" zikutanthauza zinthu zosiyanasiyana kwa ogulitsa. Ena amanena masabata 12-ndikuwonjezera masabata 3 owunikiranso uinjiniya, 2 inanso yogula zinthu, ndi 1 yokonzanso. Ena amamanga 30% padding padding "ngati zichitika."
Sititero. Kukonzekera kwathu kumagwiritsa ntchito kusanthula nthawi ya takt-osati kuyerekezera kwa kalendala. Pamaoda apakati (ma PC 50–500), timatseka mphamvu panthawi ya mawu potengera nthawi yeniyeni ya makina, matrices a luso la opareshoni, ndi kupezeka kwa ng'anjo-osati maspredishiti. Prototype imayitanitsa kutumiza m'masiku ≤14 ngati zojambula zili zoyera ndipo zida zili mgulu. Kulamula kwa voliyumu kugunda 98.7% pa nthawi yobweretsera-kuyezedwa kuyambira tsiku lotsimikizika la PO mpaka kutsitsa doko, osati tsiku la invoice.
Ndipo inde - timachita misonkhano yovuta. Kota yatha, tidatumiza chipika chathunthu cha hydraulic manifold block: thupi loyika 316L, malo olumikizirana ndi madoko opangidwa ndi makina a CNC, ndime zokhala ndi faifi wamkati, komanso kutayikira kwa helium pa 10⁻⁹ mbar·L/s. Zonse kuchokera kumalo amodzi. Zonse zokhala ndi zolemba zonse za AS9102 zikuphatikizidwa.
Kwa mainjiniya omwe amapeza ma aloyi apamwamba kwambiri, odalirika kwambiri, makamaka ma hydraulic, mafuta & gasi, kapena magalimoto olemera - a Precision Investment Casting Company Factory ayenera kupereka zambiri kuposa magawo. Iyenera kupereka kulosera: muzitsulo, mu geometry, mu nthawi. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapanga kuneneratu kumeneko mu sitepe iliyonse - osati monga lonjezo, koma monga zotulukapo zomwe zingayesedwe. Nthawi ina pamene mapangidwe anu adzafuna pulagi ya cobalt alloy kapena maziko a chitsulo chosapanga dzimbiri, musafunse kuti "ndani angapange?" -koma "ndani wapanga kale 10,000, chimodzimodzi chonchi?"
