Nyumba ya pampu ya hydraulic ikasweka pansi pa mipiringidzo 350, kapena mphuno ya aloyi ya cobalt ikakokoloka pambuyo pa maola 400 muntchito ya gasi wowawasa, mainjiniya amasiya kufunsa "Tigwiritse ntchito chiyani?" Amafunsa kuti: “Ndani angathe kupanga makina makonda aloyi Machining mbali zomwe sizidzatha pa tsiku la 47?"
Funso limenelo si lanthanthi. Tidaziwona m'ma OEM atatu aku North America opangira mafuta chaka chatha-iliyonse ikuyang'anizana ndi nthawi yosakonzekera chifukwa ma aloyi a pashelefu sanathe kupirira kulekerera kwa GD&T ± 0.015 mm pomwe akukana kuponya kwa chloride pa 120 ° C. Standard zosapanga dzimbiri zokhotakhota. Inconel 625 idadulidwa pamizu ya ulusi. Yankho limodzi lokha lomwe linalipo: kuponya kochokera ku T800 kobalt, komalizidwa ndi kuwongolera kupsinjika kwamafuta ndikutsimikiziridwa kudzera pa CMM pamalo aliwonse ovuta.
Apa ndipamene makina a alloy aloyi amasiya kukhala chinthu chamzere wogula-ndikukhala chida chodalirika. Zimafuna zambiri kuposa luso la CNC. Pamafunika kuwongolera zitsulo, kutsata njira, komanso luso laumisiri pamalo opangira mankhwala opangira kutentha. Ndi ogulitsa ochepa omwe amagwira ntchito pamzerewu. Ochepera amalembabe.
Chifukwa Chake Cobalt-Nickel Alloys Amafuna Zambiri Kuposa "Zabwino Zokwanira" Machining
Cobalt-nickel superalloys ngati AMS 5387 kapena T800 sizovuta kupanga makina chifukwa "ndizovuta." Ndizovuta chifukwa ntchito yawo yowumitsa ntchito imaposa 300% panthawi yodulidwa, kutentha kwawo kumakhala pansi pa 12 W / m·K, ndi kusagwirizana kwa microstructural-ngakhale 5-8 µm kugawanika kwa carbide-kuyambitsa macheza a zida zomwe zimawononga kukhulupirika pamwamba pa nkhope zosindikiza.
Tidalandirapo chojambula chamkono wapampu wa AMS 5387 wokhala ndi chofunikira cha 0.008 mm Ra pabowo lamkati la 120 mm. Wopereka kasitomala wakale adagwiritsa ntchito zoyikapo za carbide ndi zoziziritsa kupyola mu spindles. Zotsatira zake? Misozi yapamtunda ya 80 mm kuya, kusuntha kwapang'onopang'ono kupitirira ± 0.025 mm, ndi 37%. Kukonzekera kwathu sikunali "zida zabwinoko." Zinali zitatu zogwirizana zochita: (1) chisanadze Machining kutentha mankhwala kuti homogenize carbide kugawa; (2) kutsirizitsa maulendo angapo ndi zoyika za ceramic zomwe zikuyenda pa 42 m / min-pang'onopang'ono, koma yokhazikika; (3) in-process air-gauging iliyonse 15 mm kusintha chipukuta misozi pamaso kupatuka kupitirira 0.005 mm.
Mulingo wowongolera uwu umalekanitsa magawo ogwirira ntchito ndi omwe ali ofunikira kwambiri. Ma valve opanikizika samatha chifukwa zisindikizo zimakwanira - zimatsikira pamene zibowo za nyumba zimapotoza pansi pa torque ya clamping. Kupotoza kumeneko kumayamba kalekale kudula komaliza kusanadulidwe: mukuyenda kwambewu zopangira, kupsinjika kotsalira kuchokera kumitengo yozizirira, m'matenthedwe otenthetsera panthawi yoyatsa. Makina amtundu wa alloy ayenera kuyang'anira zonse zitatu - osati kungochotsa zitsulo.
Kuphatikiza Koyima Si Buzzword-Ndi Mzere Wanu Woyamba Wachitetezo
Mashopu ena akutulutsa kunja. Ena amapereka chithandizo cha kutentha kwa kunja. Gulu lachitatu limayang'anira ntchito zakunja. Chiwongola dzanja chilichonse chimawonjezera zosinthika: chemistry yosagwirizana, nthawi zonyowa za ng'anjo zosajambulidwa, kusanja kwa gage kosalembedwa. Gawo lanu likakanika, kutsata zomwe zayambitsa mavenda atatu kumatenga milungu - osati maola.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kuponyera, CNC Machining, ndi kumaliza kumachitika pansi pa denga limodzi logwirizana ndi ISO - ndi metrology yogawana, kufufuza zinthu zolumikizana, komanso kutsimikizika kwapang'onopang'ono. Billet iliyonse ya cobalt alloy imakhala ndi ID yokhala ndi QR-code yolumikizana ndi lipoti lake loyesa mphero, kujambula filimu ya X-ray, chipika chopindika cha kutentha, ndi lipoti loyamba la CMM. Ngati nyumba ya silinda ya pisitoni ikuwonetsa kuvala kosayembekezereka pakuyesa kumunda, timakoka mapasa a digito - osati pepala lomaliza loyendera.
Kuphatikiza uku kumabweretsa zotsatira zoyezeka:
- Kukhazikika kwapang'onopang'ono kumapangidwa bwino ndi 40% pamatupi olimba a ma valve (0.8 mm makulidwe a khoma, Ø142 mm OD)
- Kubwereza komaliza kwapamwamba kumangiriridwa kuchokera ku ± 0.03 mm Ra mpaka ± 0.007 mm Ra pa nozzles T800
- Nthawi yotsogolera ya madongosolo apakati a AMS 5387 yachepetsedwa ndi masiku 22 motsutsana ndi maunyolo ogawanika.
Imathandiziranso njira zosakanizidwa, monga ma cores-cast T800 cores okhala ndi makina omaliza a CNC-omwe amachotsa ma angles owongolera ndikuchepetsa kuchotsa katundu ndi 65%. Izi sizowononga ndalama. Ndiko kuchepetsa chiopsezo chopangidwa mu geometry.
Kutsimikizika Kwapadziko Lonse: Kodi "Kulondola" Kumatanthauza Chiyani M'zinthu Zamakampani
Kulondola sikumatanthauzidwa ndi kuwerengera kwa micrometer kokha. Zimatsimikiziridwa mu ntchito. Timayesa nyumba iliyonse yokakamiza ya valve yokhala ndi umboni wa hydrostatic pa 1.5 × kugwira ntchito, kenako kuizungulira nthawi 5,000 kudutsa kutentha kwake. Winch center shaft roller iliyonse imatsimikiziridwa mokhazikika pa 3,200 RPM-ndikuyang'anitsitsa zowonongeka zapansi pa nthaka pogwiritsa ntchito fluorescent penetrant pa ASTM E1417.
Makasitomala nthawi zambiri amafunsa kuti: "Kodi mungafanane ndi nthawi yotsogolera yomwe ilipo?" Timayankha ndi deta-osati malonjezo. Mwachitsanzo, European engineering galimoto OEM ankafunika mayunitsi 280 a cobalt aloyi pulagi (AMS 5387, Ø86 mm × 192 mm, ndi 6 ulusi mkati M24×2). Wogulitsa wawo wam'mbuyomu adatchula masabata a 14, popanda thandizo lokonzanso. Tidapereka zolemba zoyambirira m'masabata 6 - kuphatikiza kuwunika kwa GD&T, kulumikizika kwa certification, ndi mayankho akupanga zomwe zidapangitsa kuti ma radiyo awiri osagwira ntchito akhale osavuta. Kutumiza komaliza: masabata a 10. Zero dimensional rework.
Liŵiro limenelo linabwera chifukwa chothetsa malingaliro—osati kungodumphadumpha. Tidatsimikizira kuuma kwakuthupi tisanayambe roughing. Tinachepetsa kuyeserera pamtengo woperekera nsembe kuchokera kutentha komweko. Tinkayeza zovala za zida mphindi 12 zilizonse - osati masinthidwe aliwonse.
Kusankha Wothandizira Pamakina a Aloyi Mwachizolowezi: Yang'anani Kupyola Kabukuka
Ngati polojekiti yanu yotsatira ikukhudza cobalt-nickel, high-strength stainless, kapena nickel-iron alloys, funsani mafunso awa musanasaine PO:
- Kodi mumayang'anira mbiri yonse ya matenthedwe—kuyambira kuzirala mpaka nthawi yomaliza yochepetsera nkhawa?
- Kodi mungapereke kutsatiridwa kwazinthu zonse kubwerera ku batch yosungunuka, kuphatikiza zotsatira za mayeso a intergranular corrosion?
- Kodi mumatsimikizira bwanji kukhazikika pazigawo zokhala ndi mipanda yopyapyala mukamaliza kukonza ndi kuyeretsa?
- Kodi ndondomeko yanu yolembedwa bwanji yoyendetsera zida zogwiritsira ntchito > 40 HRC ndi > 30% kuuma kwa ntchito?
Mayankho amavumbula zambiri kuposa luso. Amawulula ngati wogulitsa akuwona gawo lanu monga momwe akufunira - kapena ngati gawo ladongosolo lomwe lili ndi zotsatira zenizeni padziko lapansi.
Kupanga aloyi mwachizolowezi sikungopanga zitsulo kuti zigwirizane ndi chojambula. Ndizokhudza kupanga zojambulazo ziwonetsere zomwe chitsulo-ndi ntchito-ingathe kupereka. Izi zimafuna chidziwitso cholephereka, ukatswiri wotsimikizirika pakulolerana, ndi chidaliro chomwe chimapezedwa kudzera m'ma data omwe angapezeke - osati zotsatsa. Kupanikizika kukachuluka, kulondola kumakhalabe. Sankhani moyenerera.
