Mukufuna zigawo zachitsulo zolondola - mwachangu? Osati "kufulumira kuponya." Rapid Investment casting Factory kutanthauza kutembenuza zinthu zovuta, zowona mtima kwambiri monga AMS 5387 cobalt alloy pump housings kuchoka ku zojambula kupita ku kutumiza mkati mwa masiku 21. Izo siziri mathamangitsidwe. Ikukonzanso ndondomeko ya nthawi.
Tapereka magulu otembenuka mwachangu opitilira 1,200 kuyambira 2020-makamaka ma valve okakamiza, ma silinda a pampu ya pistoni, ndi zodzigudubuza za winnch center shaft za ma OEM a hydraulic kudutsa North America ndi Europe. Zomwe zimapangitsa kuti zigwire ntchito si liwiro lokha. Ndi momwe kuponyera mwamphamvu, makina, ndi kuwongolera zitsulo kumatsekera pamodzi.
Ambiri oyambitsa amawona kuponya ndalama ngati njira yodziyimira yokha. Amathira phula, zipolopolo zozimitsa moto, kuponya, kenako n’kukapereka kumalo ogulitsira makina—ngati alipo. Kuchedwetsa kuchulukira: kukonza machiritso a kutentha, makina oyezera makina (CMM) chotsalira, mipata yotsata zinthu. Tidawona kasitomala wina akudikirira masiku 47 kuti atsimikizire makulidwe a khoma pa pulagi yamafuta & gasi. Zolinga zawo zimafuna kulekerera kwa ± 0.05 mm pa gawo la 120 mm la cobalt-nickel. Kuchedwa sikunali chifukwa cha kuchedwa-kunali kugawanika.
Yankho lathu limayamba ndikuphatikizana molunjika-osati ngati buzzword, koma ngati kachitidwe ka tsiku ndi tsiku. Mapangidwe amtundu wa sera amachitika limodzi ndi kuwunika kwa GD&T. Nthawi yowotcha ya chipolopolo cha nkhungu imagwirizana ndi kupezeka kwa ng'anjo * ndi * CNC zolosera za spindle. Kuwongolera kutentha kumatsimikiziridwa kale pa giredi iliyonse ya aloyi—AMS 5387, T800, F22 chitsulo—chotero palibe gulu lomwe limadikirira mbiri yamafuta. Ingot iliyonse ya cobalt alloy ingot imakhala ndi malipoti oyesa mphero; gawo lililonse lomwe lamalizidwa limasunga kuchuluka kwa kuchuluka kwa nambala yolipirira ng'anjo.
Izi zimachotsa mfundo zitatu zolephera zomwe zimachitika pama projekiti othamangitsa mwachangu:
- Dimensional Drift pakati pa kuponyera ndi kumaliza Machining-kuthetsedwa posunga kulolerana kwa ± 0.3 mm pankhope zovuta, kenako kugwiritsa ntchito kutsimikizira kwa CMM musanayambe kugaya komaliza
- Kusagwirizana kwa Microstructure mu ma castings apamwamba a alloy-Kuyankhidwa kudzera pamitengo yozizirira yoyendetsedwa mkati mwa mzere wathu wang'anjo wotsimikizika wa ISO 9001 komanso mitengo yeniyeni ya thermocouple pa ASTM E2862
- Kuwonongeka kwapamtunda kumadabwitsa pakuwunika komaliza-Kuletsedwa ndi kuwunika kwa mawonekedwe a nkhungu zonse za zipolopolo zisanatsanulidwe ndi mapu a porosity pa 100% ya magawo a X-ray
Ena anganene kuti kuphatikiza kolimba kumapereka kusinthasintha. Koma m’machitidwe, zosemphana ndi zimenezo zimakhala zoona. Pamene wopanga mpope waku Europe amafunikira kusinthidwa kasanu ndi kamodzi ka nozzle wa aloyi wa cobalt wosakhala wamba - iliyonse imafunikira ma tweaks a geometry ndi kutsimikizika kwa njira yoyendera - tidagwiritsa ntchito ma prototypes m'masiku 11 aliyense. Chifukwa chiyani? Chifukwa mainjiniya athu adatsimikizira kuthekera koponya *panthawi ya* kuwunika kwa CAD-osati zida zitadulidwa. Palibe kujambulanso. Palibe zidutswa. Kungobwereza mobwerezabwereza mkati mwa dongosolo lomwelo.
Dongosololi limaphatikizanso mphamvu zinayi zomwe zimagwira ntchito pansi pa denga limodzi: kuyika ndalama (zamitundu yowoneka bwino mpaka 45 kg), kuponyera mchenga (kwa nyumba zazikulu), makina a CNC amitundu yambiri (5-axis munthawi yomweyo ma contours a impeller), komanso kumalizidwa kwapamwamba - kuphatikiza zokutira za HVOF pazovala zomangika ndi masitepe osasunthika. Zonse ndizofanana ndi ASME B16.34, ISO 8502-3, ndi ma protocol oyesa kutayikira kwamakasitomala.
Zomwe makasitomala amafunsa-ndi zomwe timayankha poyamba-sikuti "Zimathamanga bwanji?" Ndi "Kodi mungagwire 0.002" pa bore pamene mukusunga umphumphu wa tirigu kudzera mu fillet? Kapena "Kodi pulagi ya alloy ya T800 iyi ipulumuka 15,000 psi cyclic pakutsegula popanda kuyambitsa kwa microcrack?" Kapena "Kodi muli ndi umboni wosonyeza kuti gulu lanu la AMS 5387 likukwaniritsa zofunikira za AMS 2301?" Ife timatero. Nthawi zonse.
Kuchita kwapadziko lonse lapansi kumatsimikizira izi: 94.7% yamaoda apakati (50-500 pcs) amatumiza mkati mwa masiku ± 2 kuchokera tsiku lodzipereka. Nthawi zotsogola za prototype pafupifupi masiku 14 kuyambira kujambula kovomerezeka mpaka kuperekedwa kwa nkhani yoyamba - ndi lipoti lathunthu, ma satifiketi azinthu, ndi zolemba za NDT zikuphatikizidwa. Palibe zowonjezera. Palibe kuchotserapo.
Kuyang'ana m'tsogolo, cholepheretsa si mphamvu-ndi chiyeneretso. Magawo ochulukirapo amafuna satifiketi za EN 10204 3.2, kutsata kwa PED 2014/68/EU, kapena kulumikizana kwa API Q1. Chifukwa chake tikukulitsa kuchuluka kwa kafukufuku wathu wa gulu lachitatu ndikutsimikizira njira zosakanizidwa za ma hybrids opangidwa ndi makina osakanikirana-monga mavavu ophatikizika omwe mphete yapampando imaponyedwa *pamalo*, kenako kumangiriridwa kuti ifanane ndi tsinde.
Ngati pulojekiti yanu yotsatira ikufunika zitsulo zazitsulo zolondola-osati zojambula zokha, osati zida zamakina, koma zida zophatikizika zomwe zimamangidwa kuti zigwire ntchito mopanikizika - ndiye kuti mumafunikira zambiri kuposa maziko kapena malo ogulitsira makina. Muyenera a fakitale yothamangitsira ndalama mwachangu kumene zitsulo, geometry, ndi ndondomeko zimakumana. Osati ngati lonjezo. Monga machitidwe okhazikika.
