Akatswiri akamatchula magawo a mapampu a hydraulic, mavavu akunyanja, kapena makina opangira ma winchi olemetsa, "kutseka mokwanira" sichosankha. Kupatuka kwa 0.02 mm pampando wa nozzle wa cobalt kumatha kuyambitsa cavitation. Gulu la micro-porosity mu nyumba ya silinda ya pampu ya piston lingayambitse kutopa pansi pa njinga za 350-bar. Ichi ndichifukwa chake ma OEMs apadziko lonse lapansi ndi othandizira a Tier-1 samangochokera mwatsatanetsatane kuponyera zigawo fakitale ntchito - amawayesa ngati ma subsystems ovuta.
Kulekerera kwenikweni kwapadziko lapansi kumafuna kupanga mwambo weniweni wopanga
Tawonapo zowawa zitatu zobwerezabwereza pamawunivesite a 127: Choyamba, kapangidwe ka tirigu kosasinthika mu AMS 5387 castings kumayambitsa kuyankha kosiyanasiyana kwa chithandizo cha kutentha. Chachiwiri, ma callouts a GD&T amatanthauziridwa molakwika panthawi yopanga makina, makamaka pa coaxiality pakati pa bore ndi nkhope ya flange pa maziko a pampu a alloy T800. Chachitatu, kusagwirizana kwapamwamba: Ra 0.4 µm yotchulidwa kuti isindikize, koma yoperekedwa pa Ra 1.6 µm chifukwa cha kuuma kwa mchenga kosalamulirika CNC isanamalize. Awa si mipata yamalingaliro. Ndi zolephera zam'munda zomwe zidalowetsedwa mu malipoti autumiki kuchokera kwa ophatikiza ma valve a subsea ku Norway ndi omanganso pampu ya frac ku Texas.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pomwe zitsulo zimakumana ndi metrology. Malo ake a Qingdao samayendetsa mizere yoponyera wamba. Imayendera magawo awiri ofananira, ogwirizana ndi ISO: kuyika ndalama kwa ma geometries ovuta, okhala ndi mipanda ya cobalt-nickel - komanso kuponyera mchenga wolondola panyumba zazikuluzikulu zazitsulo / zosapanga dzimbiri zomwe zimafunikira kuwongolera makulidwe a khoma. Gulu lililonse limayamba ndi kutsatiridwa kwazinthu zovomerezeka - osati malipoti oyesa mphero, koma zolemba zonse zowunikira zomwe zimatsatiridwa ndi AMS 5387 ndi ASTM A494. Makasitomala akatumiza chojambulira cha pulagi ya AMS 5387, gululo silimangoyang'ana kapangidwe ka mankhwala komanso chiwopsezo chosiyanitsidwa ndi interdendritic potengera kulimba kwachitsanzo cha pulogalamu yawo yoyeserera.
Kuphatikizika koyima sikungolankhula - ndi inshuwaransi yayikulu
Otsatsa olondola kwambiri amagawira zinthu kwa akatswiri opanga makina akunja. Izi zimabweretsa ma vector atatu olephera: kupotoza kwa kutentha panthawi yoyendetsa, kusintha kwa data pakati pa makina opangira ndi makina, komanso kusagwirizana kwapamtunda pamalo ovuta. QINGDAO QIANGSENYUAN ali ndi njira zonse ziwiri-ndipo amalamulira handoff. Maselo awo a CNC amakhala mamita kuchokera pamalo oyeretsera. Thupi la valve yokakamiza limayenda molunjika kuchoka pakuwombera kupita ku 5-axis Hurco VMX42SS kuti liwombe komaliza ndi kuyang'ana flange. Palibe kukonzanso. Palibe kusuntha kwa recalibration. Palibe ma data otayika.
Unyolo woyimirirawu umapereka zotsatira zoyezeka: 92% gawo lopambana la gawo loyamba la magawo omwe ali ndi ± 0.015 mm kulolerana; Cpk ≥1.67 yosungidwa m'miyezi 12 yopanga ma silinda a pampu ya piston; kutsata kwathunthu mpaka kung'anjo, nthawi yothira, ndi ID yozungulira kutentha kwa gawo lililonse lotumizidwa. Kuwongolera kumeneku kumafunika pamene gawo lanu likhala mkati mwa gulu la mpope la Class I lomwe silingaphulike lomwe likugwira ntchito pa 180 ° C m'malo oyeretsera ku Southeast Asia.
Specialization imamenya sikelo —makamaka ndi ma superalloys
Mafakitale ena amati "ma alloys onse." Tasanthula masitolo asanu ndi limodzi otere. Awiri okha ndi omwe amatha kugwira mozungulira 0.03 mm pamilomo yopangidwa ndi cobalt ya T800 pambuyo pochepetsa kupsinjika. Kusiyana kwake? Njira ya Toolpath ndi kasamalidwe ka kutentha. QINGDAO QIANGSENYUAN amagwiritsa ntchito mphero yotsika-RPM, ya torque yayikulu yokhala ndi kuziziritsa kwa nayitrogeni wa cryogenic—osati koziziritsa kusefukira—kupondereza kuuma kwa ntchito ndi kung'amba pang'ono kwa faifi tambala wa cobalt. Opanga makina awo amasintha mitengo yazakudya mokhazikika kutengera mayankho a nthawi yeniyeni ya spindle, osati ma presets a CAM. Uku si kupanga mabuku. Ndiwowongolera njira yosinthira yopangidwa mu 47 iterations pa AMS 5387 pampu magawo okha.
Zogulitsa zawo zimatsimikizira cholinga: palibe zokongoletsera zokongoletsera. Palibe zomangamanga. Zomwe zimafunikira kwambiri pantchito - mavavu osindikizira omwe amasindikiza pa bar 414, zodzigudubuza za winch center shaft zomwe zimapirira 150,000-cycle torsional loads, maziko a pampu amayamwa 22 g vibration. Gulu lililonse limakakamiza kuphunzira mozama: ma hydraulic flow dynamics amipando ya ma valve, machitidwe a tribological pamalo odzigudubuza, mamapu afupipafupi anyumba zazikulu. Simungapindule nazo pogwira ntchito zapagulu.
Kudalirika kotumizira kumayamba ndi kukhulupirika kwa uinjiniya-osati malonjezo
"Mungathe kuchita izi?" ndi funso loyamba lolakwika. "Kodi njira yotsika mtengo kwambiri yokwaniritsira ntchitoyi ndi iti * ndi * kukwaniritsa zofunika pa moyo?" ndi momwe QINGDAO QIANGSENYUAN imayambira chinkhoswe chilichonse. Kuwunika kwawo kwauinjiniya kumawonetsa ngozi zopanga kupanga msanga: utali wa 0.5 mm pamphambano ya T800 yomwe imayitanitsa kung'ambika kotentha; GD&T stack-up yomwe imapangitsa kutsimikizika kwa CMM kwazinthu zinayi kukhala kosatheka popanda kukonzanso. Amabwezeranso zojambula zojambulidwa - osati masitampu "ovomerezeka" - ndi njira zina: "Sinthani kuzinthu zopangira ndalama pano - amawonjezera $ 12 / unit koma amachotsa ntchito zachiwiri za 3 ndikuwongolera kukhulupirika kwa 40%.
Kuwonekera kumeneko kumakulitsa kukhulupirirana. Chiwongola dzanja chawo pa nthawi yake chimakhala pa 98.3% pamadongosolo apakati-ngakhale ndi kusakhazikika kwapadziko lonse lapansi kwa cobalt mu 2023 - chifukwa amapanga mapulani osinthira zinthu * asanatchule. Nthawi zotsogola za AMS 5387 zitafikira kwa masabata 22, adakwanitsa kuti agwirizane ndi aloyi a T800-modified alloy kukumana ndi makina onse koma kudula nthawi yotsogolera ndi 60%. Si onse ogulitsa omwe ali ndi bandwidth ya R&D. Ochepa amagawanabe momasuka.
Kwa mainjiniya omwe amapeza zigawo zamafakitale zololera kwambiri, kusankha sikuli pakati pa kuponya ndi kukonza-ndi pakati pa ogulitsa ogawika ndi mnzake wapamodzi yemwe amawona kukhazikika kwa mawonekedwe, kukhulupirika kwa microstructure, ndi magwiridwe antchito ngati zofunika zosagawanika. Ndicho chenicheni cha ntchito kumbuyo kwa aliyense mwatsatanetsatane kuponyera zigawo fakitale kubweretsa zinthu zomwe zapulumuka—osati za sitima zokha.
