Kupanga mololera kwambiri kumafuna zambiri kuposa zokhazikika - kumafunikira kuwongolera, luso lazachuma, ndi kuyankha kwamagulu pagawo lililonse. Nyumba ya pampu ya hydraulic ikalephera pansi pa 350-bar pressure, kapena cobalt alloy nozzle imakokoloka pambuyo pa maola 200 muntchito ya gasi wowawasa, chomwe chimayambitsa sichikhala chojambula. Ndilo kusiyana pakati pa kulosera za kuchepa kwamphamvu ndi khalidwe lolimba kwenikweni. Ndiwo kutentha kosalamulirika panthawi ya chithandizo cha kutentha kwa AMS 5387. Ndi CMM probe angle misalignment pa 0.015 mm GD&T callout ya piston cylinder bore. Taziwona zonse zitatu - ndikuzikonza osati ndi ma workaround, koma ophatikizidwa mwatsatanetsatane kuponyera njira fakitale kuphedwa.
Chifukwa Chake Kulekerera Kulekerera Sikungokhudza Nkhungu
Mainjiniya ambiri amawona kuponya ngati chinthu "chosawoneka bwino" - chinthu chomwe chimadzachotsedwa pambuyo pake. Malingaliro amenewo amalephera pamene makulidwe a khoma amasiyanasiyana ± 0.8 mm kudutsa maziko a mpope a mchenga wa 420 mm, kapena pamene kupanikizika kotsalira kuchokera ku kuzizira kosiyana kumasokoneza thupi la valve yachitsulo chosapanga dzimbiri pambuyo pokonza makina omaliza. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timawona kuponya ngati ntchito yoyamba yolondola - osati yomaliza. Malo athu ogwirizana ndi ISO amayendetsa ndalama zofananira ndi mizere yoponyera mchenga, iliyonse yowerengera mabanja ena aloyi: ma aloyi a cobalt-nickel ngati T800 ndi AMS 5387 amafuna kuzizirira pang'onopang'ono, koyendetsedwa; ductile chitsulo kwa uinjiniya galimoto winch shafts amafuna yeniyeni graphite tinatake tozungulira; Zopangira zitsulo zosapanga dzimbiri zimafunika kuthira mumlengalenga kuti zisungidwe ku dzimbiri.
Timatsimikizira geometry ya nkhungu pogwiritsa ntchito kayeseleledwe ka digito—osati kungomasulira kwa CAD-to-CAM. Panyumba ya silinda ya pampu ya pisitoni, timatengera kutsika kwamafuta m'magawo 17 ovuta, kenako timasintha ma prints apakatikati ndi zitseko kuti tigwirizane ndi ID mkati mwa ± 0.12 mm makina aliwonse asanayambe. Umu ndi momwe timaperekera zojambula zomwe zimapita molunjika mpaka kumapeto - palibe kukonzanso, palibe zotsalira, palibe ndondomeko.
Kuphatikiza Koyima: Kumene Kuponya Kumakumana ndi Machining Reality
Otsatsa ena akuponya kunja, ena amapangira makina akunja. Sizimagwiranso ntchito pazigawo zomwe kulungamitsidwa kwapamwamba ndi mawonekedwe ang'onoang'ono akuyenera kulumikizidwa. Pulagi ya cobalt alloy siili yovuta chabe - imakhala yolimba ngati mbali ya mkono ya dendrite iposa 25 µm. Koma kupanga makina opitilira muyeso kuthamangitsa kutha kwapamwamba kumawononga ma microcracks. Timathetsa izi poyang'anira mbali zonse ziwiri: gulu lathu lothandizira limagawana deta yowunikira zenizeni zenizeni ndi opanga mapulogalamu a CNC. Zotsatira za spectrographic zikawonetsa 0.02% wokwera wa kaboni mu gulu la T800, njira yathu yopangira zida imasintha kuchuluka kwa chakudya ndi kuzizira kozizira - osati kuteteza choyikapo, koma kusunga kupsinjika kotsalira komwe kumatsalira.
Kuphatikiza uku kumachepetsa nthawi yotsogolera ndi 37% pamadongosolo apakati. Chofunika kwambiri, chimathetsa kusuntha kwapakati pakati pa kuponya ndi gawo lomaliza. Tayezanso kupatuka kobwerezabwereza kwa mamilimita 0.008 pamapatani 8-mabowo a flange pamayunitsi 120—mkati mwa theka la zofunika za ASME Y14.5 MMB. Kusasinthika kumeneku kumachokera ku metrology yogawana: CMM yomweyo, ndondomeko yofananira yofanana, ndondomeko yofananira ya GD&T yotanthauzira podutsa ma QA ndi kupanga magulu a QA.
Kufufuza Kwazinthu Zomwe Zimatsata
"Zinthu zotsimikizika" sizitanthauza kanthu ngati nambala ya kutentha pa chigayo sichikugwirizana ndi malo oponyera, kapena ngati chitsanzo choyezera mipiringidzo chikokedwa kuchokera kudera lina. Timatsata kilogalamu iliyonse yazinthu zopangira - kuchokera ku risiti ya T800 yotsimikiziridwa ndi supplier-certified ingot kupyolera mu kusungunuka, kuthira, mankhwala otentha, ndi kuyendera komaliza. Kuponyedwa kulikonse kumakhala ndi tag yokhala ndi QR yolumikizira kutsata kwathunthu: kapangidwe ka mankhwala pa ASTM E353, kukula kwambewu pa ASTM E112, kulimba kwa mapu kudutsa magawo osiyanasiyana, ndi malipoti a CMM pazofunikira zonse.
Kwa makasitomala amafuta ndi gasi omwe amafunikira kutsata kwa API 6A, timakulitsa kutsata kwa kuyezetsa kogwira ntchito: valavu iliyonse yamagetsi imakumana ndi umboni wa hydrostatic pa 1.5 × wovoteledwa, ndikuwerengera kupsinjika komwe kumayikidwa pagawo lililonse. Ngati kasitomala afunsa moyo wotopa pa gawo la mpope la AMS 5387, timakoka chipika cha kutentha kwenikweni, kuwerengeranso kuthamanga kwamphamvu, ndikugwirizanitsa ndi zithunzi za SEM zosweka kuchokera kumagulu ovomerezeka am'mbuyomu. Palibe zongoganizira. Palibe extrapolation. Umboni wokha.
Kulondola Kwambiri Padziko Lonse Kumayamba Ndi Zokambirana Zenizeni
Sitigulitsa ntchito zoponya—timathetsa njira zolephereka. Pamene European hydraulics OEM inanena kuti 18% yakukana panyumba za silinda chifukwa chakukula kwa ovality, sitinatchule nkhungu yatsopano. Tidayendera mzere wawo wolumikizirana, kuyeza kuchuluka kwa kutentha kwa zigawo zawo zokwerera, ndikusinthanso nthiti za oponya kuti athane ndi kusokonekera panthawi yomwe akuwongolera. Zotsatira: 99.2% zokolola zoyamba, ziro kusintha kwa zida zomwe zilipo.
Ndiko kusiyana pakati pa a mwatsatanetsatane kuponyera njira fakitale ndi maziko. Ndi chifukwa chake makasitomala aku North America, Germany, ndi Singapore amatitumizira zojambula zolemera za GD&T-osati ma RFQ okha. Akudziwa kuti tidzayikira zoopsa za kupanga zida zisanayambe: kumveka kwa 0.005 mm pamtunda wa mchenga wa 300 mm? Tikupangira kupanga ndalama m'malo mwake. Nozzle ya aloyi ya T800 yopanda muyezo yokhala ndi radii yamkati pansi pa 0.3 mm? Tidzatengera kukokoloka kochititsidwa ndi madzi ndikupangira chithandizo chamtundu wa HIP.
Pitani https://www.tsingtaocnc.com kuti muwunikenso maphunziro ovomerezeka a luso la kuponyera kwa cobalt alloy, kutsitsa maupangiri otanthauzira a GD&T, kapena kupempha kuwunikiridwa kwaulere pagawo lanu lotsatira lololera kwambiri. Kulondola sikutheka paokha-kumamangidwa kumene sayansi yoponyera imakumana ndi ukadaulo wamakina, komanso pomwe chidziwitso chilichonse chimakhala ndi kufotokozera kwenikweni.
