Akatswiri akamatchula zigawo za aluminiyamu za ma hydraulic manifolds, ma pump housings, kapena matupi a valve high-pressure, kukhazikika kwa dimensional ndi microstructural consistency sizosankha - sizingakambirane. Ichi ndichifukwa chake ma OEM aku North America ndi aku Europe tsopano amachokera ku a fakitale yoponyera phula ya aluminiyamu yotayika zomwe sizimawona kuponya ndalama ngati njira yodziyimira yokha, koma ngati sitepe yoyamba yolondola pamayendedwe oyendetsedwa bwino osakanizidwa. Tawonapo makasitomala akubwerera katatu-choyamba chifukwa cha ma prototypes, chachiwiri kwa kutsimikiziridwa kwapakati, chachitatu pakupanga mndandanda wonse-chifukwa ogulitsa awo akale sakanatha kugwira ± 0.05 mm pazitsulo zopyapyala za aluminiyamu pambuyo pa chithandizo cha kutentha. Chifukwa chake? Kusiyana pakati pa luso loponya ndi kuwongolera makina a post-cast.
Chifukwa chiyani "Nzata Yotayika" Yokha Simatsimikizira Kulondola-Ndipo Zimatani
Kuponyedwa kwa aluminiyamu wotayika kumapereka mawonekedwe amtundu wa net-net-koma pokhapokha ngati unyolo wonsewo wapangidwa kuti ukhale wodalirika. Kumalo athu ku Qingdao, timayamba ndi ma AMS 4117 kapena A380 alloy billets ovomerezeka ku ASTM B179, kenako kutsimikizira kapangidwe ka tirigu pogwiritsa ntchito zitsanzo za metallographic pamaso pa chipolopolo cha nkhungu. Chofunika kwambiri, sitimatulutsa zida zapatani za sera: ambuye athu opangidwa ndi aluminiyamu opangidwa ndi CNC amalola kuti tisinthe ma angles ndi malo olowera mkati mwa 0.02 mm-yovuta kwambiri poponya nyumba za silinda zokhala ndi njira zozizirira zamkati pansi pa makulidwe a 2.5 mm.
Tawona kuti 70% ya kugwedezeka kwamphamvu muzopanga za aluminiyamu kumachitika panthawi ya de-waxing ndi kutopa-osati kuthira. Mng'anjo zathu zokonzedwanso zimakwera pa 0.8 ° C / min mpaka 1050 ° C, kugwira kwa mphindi 90 kuchotsa sera yotsalira popanda kung'amba zipolopolo za silika-alumina. Kuwongolera kumeneku kumafunika kwambiri pazigawo monga piston pump silinda nyumba, komwe kutenthedwa kwamafuta panthawi yakupsa kumapanga ming'alu yaying'ono yomwe pambuyo pake imafalikira pansi pa kukakamizidwa kwa cyclic.
Mosiyana ndi masitolo opangira mchenga omwe amawona aluminiyumu "yosavuta kuthira," timawunika kutentha kwa ± 3 ° C pogwiritsa ntchito njira ziwiri zomiza za thermocouple - ndikukana batch iliyonse yomwe haidrojeni imaposa 0.12 ml / 100g (yoyesedwa ndi kuyesa kwa vacuum solidification). Izi sizowonjezera; ndimomwe timapezera mphamvu zolimba ≥310 MPa mu nyumba za A380 zothandizidwa ndi T6 pomwe tikusunga kutalika> 3.5%.
Kumene Kuponyera Kutha ndi Umisiri Weniweni Umayambira
Izi ndi zomwe ambiri fakitale yoponyera phula ya aluminiyamu yotayika mindandanda sangakuuzeni: kulondola kwa ndalama zoyendetsera ndalama kumatsika mwachangu kupitilira 300 mm mugawo lililonse. Ndicho chifukwa chake selo yathu ya CNC imakhala mamita kuchokera pamzere woponyera-osati kudutsa nyumba yosungiramo katundu. Timapanga makina osindikizira ofunikira, mabowo okwera, ndi kutulutsa zibowo mkati mwa maola 4 a shakeout, kuchepetsa kupsinjika kwa matrix a aluminiyamu.
Timagwiritsa ntchito makina ozungulira ma axis asanu munthawi imodzi pamagawo ngati ma roller a winch center shaft, pomwe kukhazikika pakati pa 120 mm OD magazine ndi 65 mm ID bore kuyenera kukhala ndi 0.015 mm chiwerengero chonse. Palibe chithandizo cha kutentha pambuyo pa makina omwe amagwiritsidwa ntchito pokhapokha atatchulidwa-chifukwa kutenthedwanso kumasokoneza gawo lapamwamba lopangidwa panthawi yokhazikika. M'malo mwake, timayika mpumulo wa kugwedezeka kwa mphindi 30 tisanayambe kuyang'ana komaliza kwa CMM.
Protocol yathu yowunikira siimayendetsedwa ndi mndandanda - imayendetsedwa ndi ntchito. Pama valve opanikizika, sitimangotsimikizira ma callout a GD&T koma mitengo yeniyeni yotayikira mipando motsutsana ndi miyezo ya ISO 5208 Class A. Gawo lirilonse limakhala ndi chizindikiro cholumikizira cholumikizira nambala yake ndi ma cert, matabwa ang'anjo, malipoti a CMM, ndi data yoyeserera ya helium.
Pamene Cobalt Alloys Lowetsani Chithunzi-Ndipo Chifukwa Chake Aluminiyamu Imatsogolerabe
Ena amaganiza kuti mbali za cobalt-nickel zikutanthauza kusiya aluminiyamu. Osati pano. Timakonda kuponyera nyumba za aluminiyamu zomwe zimaphatikizira ma nozzles a cobalt alloy (AMS 5387) kudzera m'makina osindikizira olondola-otsimikiziridwa ndi kuyezetsa kwa ultrasonic bond. Thupi la aluminiyumu limagwira ntchito zomanga; choyikapo cobalt chimakana kukokoloka kwa kutentha kwa 220 ° C. Njira yosakanizidwa iyi imadula mtengo ndi 38% motsutsana ndi monolithic cobalt kuponyera pokumana ndi malire a liwiro la API RP 14E.
Tapanga zobwereza 17 za mphete yolondolera pampu yochokera ku T800 yosakhazikika-iliyonse yoyeretsedwa kutengera kulephera kwamunda kuchokera ku zida zamafuta zakunyanja. Koma maphunziro amenewo adathandizira mwachindunji njira yathu yopangira aluminiyamu: kuwongolera molimba kwa malo ochezera apakati kunachepetsa porosity m'matupi a valve a A380 omwe amakhala ndi madzi odzaza ndi H₂S. Ukatswiri wa zinthu zakuthupi sunasinthidwe - umasinthidwa.
Kukonzekera kwathu kowonda kumawonetsetsa kuti nthawi yotsogolera imakhala masiku osakwana 21, ngakhale ma geometries ovuta omwe amafunikira ma cores a ceramic. Pazinthu zoyitanitsa ma voliyumu, timasunga zosungiramo zinthu zofananira ndi zipolopolo, kuti kutsatiridwa kwazinthu kusakhale cholepheretsa kutumiza.
Kusankha Wokondedwa, Osati Wongopereka
Ngati polojekiti yanu yotsatira yopangira aluminiyamu ikukhudza makoma opyapyala, tinjira tamkati, kapena kulolerana kolimba pazinthu zamakina, funsani mafunso awa musanasaine PO:
- Kodi mungawonetse malipoti a CMM otsimikizira kusalala kwa 150 × 150 mm pamwamba?
- Kodi mumasanthula ma hydrogen pamtundu uliwonse wosungunuka - kapena sabata iliyonse?
- Kodi mapulogalamu anu a CNC amachitika m'nyumba, kapena amaperekedwa kwa wogulitsa wina?
- Kodi ndondomeko yanu yolembedwa yotsimikizira kusintha kwakukulu m'magawo opanda kanthu ndi chiyani?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha onse anayi ndi data yotsimikizika—osati timabuku. Sitigulitsa ntchito zoponya. Timapereka zida zogwirira ntchito za aluminiyamu zomwe zimapulumuka kuzungulira kwamphamvu kwa 10,000+ m'ma hydraulic system, kutumizidwa kwazaka 5 m'mapampu am'madzi, ndikugwira ntchito mosalekeza pamawilo amagalimoto a engineering. Kudalirika kumeneko kumayamba kalekale sera isanasungunuke-ndipo imatha pokhapokha wogwiritsa ntchito atazimitsa.
