Mainjiniya akamatchula zigawo za aluminiyamu za ma hydraulic manifolds, mapampu, kapena makina opangira ma winch agalimoto, sayamba ndi "kuponya mchenga." Amayamba ndi vuto: kupalasa njinga zotentha kwambiri, kulolerana kwa GD&T kolimba, kuthamanga kwapakati pa 350+ bar-ndi zero malire a micro-porosity kapena dimensional drift. Ndiko kumene a mchenga kuponyera aluminiyamu fakitale imasiya kukhala wogulitsa ndipo imakhala yowonjezera mapangidwe. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tawona kulephera katatu kobwerezabwereza pamapulojekiti oponyera mchenga a aluminiyamu-osati kuchokera ku machitidwe osauka a foundry, koma kuchokera ku ziyembekezo zolakwika pa engineering handoff.
Choyamba: poganiza kuti "aluminium" amatanthauza A380. Sizikutero. M'sitolo yathu, 75% ya mchenga wa aluminiyamu umayenda pa A383 kapena mitundu 319 yosinthidwa mwamakonda-makamaka chifukwa cha madzi owonjezera pazipo zopyapyala zokhala ndi khoma komanso makina abwinoko pambuyo pa kutentha kwa T6. Chachiwiri: kuyang'ana nkhungu mchenga kugawa mbewu. Timagwiritsa ntchito silika wopangidwa ndi utomoni wokhala ndi 45-75 µm gradation-osati chifukwa ndi muyezo, koma chifukwa amadula roughness pamwamba (Ra) ndi 30% motsutsana ndi mchenga wobiriwira chikhalidwe, kuchepetsa post-cast akupera nthawi pa silinda nyumba flanges. Chachitatu: kulumpha kayesedwe ka FEA kamene kanali kolimba. Makasitomala wina waku North America adatitumizira chojambula chapampu ya pistoni chokhala ndi nthiti yokhuthala mamilimita 22 moyandikana ndi khoma la 6 mm. Kuyerekezera kudawonetsa malo omwe ali pachiwopsezo chachikulu. Tidapereka lingaliro la kuzizira kokhazikika - ndikuchotsa 100% ya zibowo zamkati zomwe zidalephera gulu lawo loyamba la X-ray.
Zomwe zimasiyanitsa wokhoza mchenga kuponyera aluminiyamu fakitale kuchokera ku imodzi yomwe imapereka magawo ofunikira kwambiri? Kuphatikiza koyang'ana-osati kuponyera kokha, koma unyolo wathunthu kuchokera ku kusankha kwa aloyi kupita ku chitsimikizo chogwira ntchito. Timangopeza ma ingots ovomerezeka a aluminiyamu okhala ndi malipoti athunthu oyesa mphero (ASTM B179, EN 1706), kenako timasanthula OES pa batch iliyonse yosungunuka. Palibe kuchotserapo. Ma cell athu opangira makina a CNC amakhala mita kuchokera pa shakeout station - kotero kuti ma castings amasunthika molunjika popanda kupumula chifukwa cha kutentha. Ndimo momwe timagwirira ± 0.05 mm pa malo a ma valve, ngakhale pa 420 mm kutalika kwa nyumba. "Sitikuyesera" kugunda kulolerana. Timayendetsa njira yotentha kuchokera kutsanulira mpaka kumapeto.
- Kugwirizana kwa Cobalt-alloy: Inde—timakonda kuponyera aluminiyamu mozungulira zoikamo za cobalt-nickel (AMS 5387, T800) pamisonkhano yapampu yosakanizidwa. Chinsinsi ndikutsanulira motsatizana komanso kuwongolera kutentha kwapakati pa ± 15 ° C wa eutectic point.
- Kukonzekera kwa GD&T: Timatsimikizira malo, mbiri, ndi kutha ntchito pogwiritsa ntchito Zeiss CONTURA CMMs-osati poyang'anitsitsa komaliza, koma pambuyo pokonza movutikira komanso pambuyo pochotsa nkhawa.
- Kutsata: Kujambula kulikonse kumakhala ndi code ya QR yokhala ndi laser yolumikizana ndi chipika chake chosungunuka, lipoti la x-ray, kuwerenga kuuma, ndi satifiketi yowoneka bwino - palibe mapepala, palibe zotayika.
Ena amatsutsa kuponya mchenga sikungafanane ndi kuyika kwa ndalama kwa ma geometries ovuta a aluminiyamu. Koma zovuta sizimawerengera gawo-komanso kuchulukana kwa magwiridwe antchito. Winch center shaft roller imafuna kugawa kokwanira bwino, kutsirizika kwapamwamba pa OD, ndi kuyanjanitsa kwanjira yolondola pamtunda wa mita 1.2. Kuponyera mchenga kumagwira bwino kwambiri kuposa ndalama pamene makulidwe a khoma amasiyana kuchokera 8 mm mpaka 45 mm. Chifukwa chiyani? Chifukwa timayang'anira kuziziritsa pogwiritsa ntchito kuzizira kokhazikika komanso manja otsekera, osati nkhungu zokha. Tapereka ma 210 kg aluminium castings ndi Cpk> 1.67 pamabotolo ovuta, otsimikiziridwa pansi pa katundu pa 400 bar hydraulic test rigs.
Kutumiza kwapadziko lonse lapansi kumadalira zinthu ziwiri zomwe ogula ambiri amanyalanyaza: kukonzekera zinthu komanso kuwonekera poyera. Timasunga ma alloys A383 ndi 319 m'magulu a 500 kg-owunikiridwatu, owumitsidwa kale, okonzeka kusungunuka mkati mwa maola 24 otsimikizira. Ndipo timagawana zosintha zenizeni zenizeni: osati "kungoyambira," koma "kusonkhanitsa nkhungu kumalizidwa nthawi ya 09:22, kuthira koyenera 14:00, kugwedezeka kukuyembekezeka 18:40." Kuwoneka kumeneko kumapangitsa magulu ogula zinthu kugwirizanitsa mayendedwe, magulu a QA kukonza malo a CMM, ndipo akatswiri opanga mapangidwe amatsimikizira kukula kwa nkhani yoyamba ntchito zachiwiri zisanayambe.
Ngati pulojekiti yanu yotsatira yopangira aluminiyamu ikufuna zambiri kuposa pepala la mawu-ngati imafuna kuzindikira kwazitsulo, kukonza mawonekedwe a makina opangira makina, ndi kutsata zolembedwa zamafuta & gasi kapena ma hydraulics am'manja - mukufunikira mnzanu amene amachitira mchenga ngati njira yopangidwa, osati chinthu chofunika. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito mwanjira imeneyi-osati chifukwa imamveka bwino patsamba lawebusayiti, koma chifukwa ma valve opanikizika amatsika, ma pompu amang'ambika, ndipo ma winch shaft amalephera pamene zongoganiza zimalowa m'malo mwa data. Timamanga zida za aluminiyamu zomwe zimapulumuka mizunguliro 10,000 yoyamba - ndi 100,000 yotsatira.
