Monel 400 Machining fakitale - mawuwa akuwonetsa zambiri kuposa kuthekera. Zimasonyeza kukonzekera ntchito zovuta kwambiri: nyumba zokhala ndi mphamvu zambiri za hydraulic, zigawo za pampu zamadzi a m'nyanja, ma valve a mpweya wowawasa, ndi zida za m'mphepete mwa nyanja kumene kukana kwa dzimbiri kumakumana ndi kuwongolera kwa geometry ya micron-level. Tapanga makina a Monel 400 kwa makasitomala ku Houston, Rotterdam, ndi Singapore - ndipo nthawi zonse, vuto lomwelo limabwera msanga: kuuma kwa zinthu panthawi yodula kumapangitsa kuti zida zivale mwachangu, kung'ambika pamwamba, komanso kugwedezeka ngati njira sizikutsekedwa chip choyamba chisanawuluke.
Chifukwa chiyani Monel 400 Imafunikira Masitolo Osiyanasiyana a Precision
Monel 400 si chitsulo chosapanga dzimbiri. Ndi 67% nickel, 23% yamkuwa, yokhala ndi zowonjezera zazing'ono koma zovuta zachitsulo, manganese, carbon, ndi silicon. Mphamvu yake yokhazikika imakhala pakati pa 790-965 MPa - yokwera kuposa 316 zosapanga dzimbiri - ndipo matenthedwe ake amatenthedwa ndi 23 W/m·K basi. Kutentha kochepa kumeneku kumatanthauza kudula kutentha kumakhala kotsekeredwa pa mawonekedwe a chida-workpiece. Kuyika kwa carbide kwanthawi zonse kumalephera mwachangu. Kutentha kwa madzi ozizira kuyenera kukhala kwakukulu, kolunjika, komanso kosasokonezeka. Mitengo ya chakudya imatsika 30-40% motsutsana ndi Inconel 625. Ndipo kugwedezeka kulikonse? Imatanthawuza mwachindunji macheza omwe amawononga kumapeto kwa malo osindikizira kapena zolemba zokhala ndi magazini.
Tawona makasitomala akutumiza zopanda kanthu za Monel 400 kumashopu atatu osiyanasiyana - kungotenga magawo omwe ali ndi ID yozungulira yosagwirizana, cholakwika chotsogola chakunja, kapena kung'amba pang'ono pafupi ndi ngodya zakuthwa zamkati. Choyambitsa chake sichinali luso la ogwiritsa ntchito. Inali njira yolakwika yogwiritsira ntchito zida, kapangidwe ka tirigu wosatsimikizirika, ndipo panalibe kuyang'anira momwe kutentha kumayendera. Makina a Real Monel 400 amafunikira chidziwitso chophatikizika chazitsulo - osati mapulogalamu a CNC okha.
Momwe Fakitale Yowona ya Monel 400 Imawongolera Zosintha
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachitira Monel 400 ngati dongosolo - osati kalasi yakuthupi. Dongosolo lililonse limayamba ndi mbale kapena mbale ya ASTM B127 yotsimikiziridwa ndi gulu, yotsimikiziridwa ndi kukula kwambewu (ASTM E112), kukana kwa dzimbiri kwapakati (ASTM G28 Njira A), ndi kulimba kufananizidwa kudutsa magawo osiyanasiyana. Palibe kuchotserapo.
Kenako timapanga mapu a magawo ogwirira ntchito: nkhope zosindikiza zimafunikira Ra ≤0.4 μm; zitsulo zokhala ndi mphamvu zimafuna ± 0.005 mm kuzungulira kutalika kwa 120 mm; madoko opangidwa ndi ulusi amafunikira ulusi wamtundu wonse ndikuwunika kwa Go/No-Go pa ASME B1.20.1. Pokhapokha m'pamene timasankha zida - zobowolera nsonga za PCD zamabowo akuya, zoyikapo zopukuta za ceramic kuti amalize kupita, ndi mphero zomalizidwa bwino zopangira mikombero ya ma impeller hubs.
Malo athu ogwirizana ndi ISO ali ndi malo opangira makina ambiri okhala ndi nthawi yeniyeni yowunikira komanso kuyang'anira kutentha kozizira kotseka. Ngati mphamvu ya chida ipitilira 12% ya zoyambira, makinawo amangoyima - palibe zongoyerekeza, palibe zotsalira.
Kumene Zomwe Zachitika Zimasanduka Zotsatira Zobwerezabwereza
Makasitomala m'modzi amafunikira 42 Monel 400 piston pump cylinder housings for subsea hydraulic systems. Wogulitsa wawo woyamba adapereka magawo 17 - onse adalephera kuyesa kutayikira kwa helium pa bar 300. Choyambitsa? Micro-porosity yochokera kuzinthu zopangira chakudya, zophatikizidwa ndi nkhanza zaukali zomwe zidatsegula ma voids apansi panthaka. Tidakonzanso zomangazo: zidayamba ndi zopangira ndalama (zogwirizana ndi AMS 5380), kuwonjezera kuyesa kwa ultrasonic musanapange makina, kugwiritsa ntchito mphero zokha, ndikusunga zololeza zomaliza za ID ku Ø142.000+0.0100 mm yokhala ndi kutsata kwa CMM pagawo lililonse komanso kutentha kwambiri.
Nkhani ina: AMS 5387 cobalt alloy nozzles wophatikizidwa ndi ma adapter a Monel 400 flange. Zida zonsezi zimagwira ntchito mosiyana pansi pa kutentha kwa njinga. Tidayesa zofananira zokulitsa matenthedwe, kusokoneza koyenera, ndikutsimikizira kupsinjika kwapamsonkhano ndikuyesa strain-gauge - osati kungoyang'ana mawonekedwe. Ndimomwe mumapewa kulephera kumunda pa 180 ° C ndi 450 psi.
Izi sizinthu zongopeka chabe. Zalembedwa mu Malipoti athu amkati Otsimikizira Njira - zopezeka kwa makasitomala oyenerera pa NDA.
Zomwe Mumapeza Kuchokera ku Fakitale Yapadera ya Monel 400 Machining
- Kukonzekera koyamba: Ayi "ingoyendetsani pa VMC." Timatsimikizira chemistry, momwe mbewu zimayendera, komanso mbiri yakale yotenthetsera tisanatchule.
- Palibe zobisika rework ndalama: Kuwunika kwa kukhulupirika kwapamtunda kumaphatikizapo kuzindikira koyera (kudzera pa SEM / EDS) pamphepete mwa makina ovuta - chifukwa ntchito yolimba ya Monel 400 ikhoza kuyambitsa ming'alu ya kutopa pansi pa kukweza kwa cyclic.
- Kukonzekera kwathunthu kwa GD&T: Timatanthauzira malo, mbiri, ndi kuyitanidwa kothamanga osati kulolerana - koma ngati zofunikira zogwirira ntchito. Kulekerera kwa 0.02 mm pabwalo la bawuti sikukhudza malo. Ndizokhudza kuwonetsetsa ngakhale mphamvu yothina pamawonekedwe a gasket amadzimadzi.
- Traceability yomangidwa: Gawo lililonse limatumiza chiphaso chosonyeza nambala ya kutentha kwa zinthu, kukonzanso pulogalamu ya CNC, ID ya lipoti la CMM, ndi ID ya opareshoni - osati sitampu chabe.
Monel 400 Machining fakitale si mndandanda wamalonda. Ndi kudzipereka ku chilango chazitsulo, kuwonekera kwa ndondomeko, ndi kuyankha kwaumisiri. Chigawo chanu chikagwira ntchito m'malo okhala ndi chloride wolemera, wopanikizika kwambiri, osasamalira ziro - kunyengerera sichosankha. Kulondola ndiye maziko. Kudalirika ndiko kuperekedwa.
Ngati polojekiti yanu yotsatira ya Monel 400 ikufuna kukhazikika, kukhulupirika pamwamba, ndi kutsatiridwa kwathunthu kwa zinthu - yambani ndi mnzanu yemwe amagwiritsa ntchito ma aloyi a nickel-copper monga momwe alili: machitidwe ofunikira kwambiri, osati zitsulo.
