Pofufuza zitsulo zosapanga dzimbiri ndalama kuponyera fakitale othandizana nawo pazigawo zofunika kwambiri, mainjiniya ndi oyang'anira zogula samangofunika ogulitsa - amafunikira kukulitsa luso la gulu lawo lopanga. Tawona mapulojekiti ambiri akuchedwa chifukwa cha kugwedezeka kwa ma valve, ma microcracks m'zigawo zapampu za cobalt-alloy pambuyo pa kutentha kwa kutentha, kapena kutha kwa pamwamba pazitsulo zosapanga dzimbiri zomwe zalephera kuyesa kupopera mchere poyang'ana komaliza. Izi siziri zolephera zokha. Ndizizindikiro za kuthekera kogawanika-kumene kuponyera, kukonza makina, ndi kuwongolera zitsulo kumakhala m'malo osiyanasiyana.
Chifukwa Chake Kuphatikizika Kwa Vertical Kupambana "Best-in-Class" Outsourcing
Kuponyera zitsulo zosapanga dzimbiri kumafuna zambiri kuposa kupanga mapangidwe ndi dewaxing. Pamafunika kuwongolera kolondola kwa ma solidification gradients, kukonzanso kapangidwe kambewu, komanso tsankho la interdendritic —makamaka mu 316, 17-4PH, kapena magiredi apawiri omwe amagwiritsidwa ntchito mumafuta & gasi kapena makina othamanga kwambiri a hydraulic. Otsatsa ambiri amatulutsa chithandizo cha kutentha kapena kumaliza CNC yomaliza. Izi zimapanga mipata: kulolerana kwa 0.02 mm pa nyumba ya silinda ya piston kumatha kutha panthawi yochepetsera nkhawa ngati mbiri ya ng'anjoyo siyikulumikizidwa ndi mawonekedwe a ng'anjo.
Tagwira ntchito ndi makasitomala omwe adasintha kuchokera kwa ogulitsa atatu osiyana (caster → chotenthetsera kutentha → makina opangira makina) kupita ku bwenzi limodzi lophatikizika-ndikudula nthawi yotsogolera ndi 38%, kuchepetsa zotsalira za nkhani yoyamba ndi 62%, ndikuchotsa kukonzanso chifukwa cha kusagwirizana kwa GD & T kutanthauzira. Kusiyana kwake sikunali kosavuta. Zinali zotsatirika: nambala yofanana kuchokera ku billet yaiwisi kupita ku gawo lomaliza, wogwiritsa ntchito CMM yemweyo akutsimikizira zonse monga-cast geometry ndi mawonekedwe omaliza opangidwa ndi makina, metallurgist yemweyo amavomereza njira zonse zothetsera mavuto ndi kupititsa patsogolo makina.
Kuphatikizika kumeneku sikochitika kawirikawiri - osati chifukwa sikutheka mwaukadaulo, koma chifukwa kumafuna kusamala mozama mosiyanasiyana. Mufunika mainjiniya omwe amawerenga mapepala a AMS 5387 ngati mabuku ndi akatswiri opanga makina omwe amasintha mitengo ya chakudya kutengera dendrite arm spacing yomwe imawonedwa pansi pa SEM.
Mtengo weniweni wa "Standard" Stainless Steel Castings
Ogula ena amaganiza kuti zitsulo zonse 304 zosapanga dzimbiri zimatha kusinthana. Iwo sali. Tinayesapo gulu la "standard" 304 valve matupi operekedwa ku European OEM. Kusanthula kwa labu kunavumbulutsa kuchepa kwa chromium pamalire a tirigu - chifukwa cha nthawi yayitali mu chipolopolo chowombera chisanachitike. Ziwalozo zidapambana mayeso olimba koma zidalephera kuthamangitsa dzimbiri mkati mwa maola 48 atakhazikitsa. Chifukwa chake? Sitolo yopangira zida zokongoletsedwa ndi kuchuluka, osati zitsulo.
Kuchita kwenikweni kumatengera zinthu zinayi zomwe sizingakambirane: kutsimikizika kwazinthu zopangira (chiwerengero cha kutentha chomwe chimayikidwa pakudya), kusungunuka kwamlengalenga (argon kapena vacuum ya alloys reactive), mbiri yotentha ya zipolopolo zomwe zimayikidwa kuti ziwonjezere kutenthedwa kwa aloyi, ndi njira yothetsera kuponyedwa yovomerezeka yovomerezeka ndi kuyesa kwa intergranular ASTME2s pachiwopsezo cha Practic A26. kufooka, kufooka, kapena kutopa msanga-ngakhale mbaliyo ikuwoneka bwino poyang'aniridwa ndi kuwala.
Chifukwa chake kutsogolera zitsulo zosapanga dzimbiri ndalama kuponyera fakitale Othandizana nawo amagulitsa zowonera m'nyumba, ma lab a metallography, ndi odula ng'anjo yamoto omwe amalumikizidwa ndi makina a ERP. Osati za zisudzo za ziphaso-koma kulumikiza kuzungulira kulikonse kotenthetsera ndi mamapu ang'onoang'ono olimba m'magawo ovuta.
Kumene Cobalt Alloys Amawonetsa Mipata Yakutha
Ngati chitsulo chosapanga dzimbiri chikuwonetsa kuwongolera, ma cobalt-nickel superalloys amawonetsa kuya kwenikweni kwaukadaulo. AMS 5387 cobalt alloy 6, T800, ndi mitundu ya Stellite samangokana kuvala-amafuna. Kuuma kwawo (45-55 HRC as-cast) kumawapangitsa kukhala osatheka kupanga makina popanda zida zapadera komanso kukhazikika kolimba. Komabe masitolo ambiri amatchulabe magawowa pogwiritsa ntchito malaibulale amtundu wa CNC.
Tawona ma nozzles a cobalt atakanidwa chifukwa cha "burr mopitilira muyeso" EDM itatha - tidazindikira kuti burr analidi wosanjikiza kuchokera ku chipukuta misozi chosayenera cha electrode. Ena adalephera kuyesa kukakamiza chifukwa chipolopolocho sichinasinthidwe chifukwa cha kutentha pang'ono kwa cobalt, zomwe zimapangitsa kuti pang'onopang'ono kufupike pafupi ndi khoma lopyapyala.
Ochita amphamvu kwambiri amachitira cobalt osati "chitsulo china," koma monga dongosolo: mapangidwe a zipolopolo zachizoloŵezi, mbiri ya ng'anjo yamitundu yambiri, njira zosakanizidwa (kuponyera ndalama + kugaya mwatsatanetsatane m'malo mwa CNC yonse), ndi kujambula nthawi yeniyeni yotentha panthawi ya dewaxing. Izi sizongoyerekeza. Ndizomwe zimalekanitsa ma prototypes ogwira ntchito ndi magawo okonzekera kupanga omwe amapulumuka kuzungulira kwa 10,000+ pamisonkhano yapampopi ya subsea.
Zomwe Muyenera Kutsimikizira Musanamalize Othandizira Pafakitale Yanu
Osadalira timabuku kapena ziphaso za ISO zokha. Funsani umboni wa chilango cha ntchito:
- Kufufuza kwazinthu: Kodi angapereke malipoti oyesa mphero olumikizidwa ndi nambala yanu ya PO-ndikuwonetsa momwe manambala a kutentha amayendera poponya, kutentha, ndi makina opangira makina?
- Kutsimikizika kwa dimensional: Kodi amagwiritsa ntchito ma CMM okhala ndi ma probe olipidwa ndi kutentha pazigawo zosapanga dzimbiri ndi cobalt? (Miyezo yosalongosoka imakwera mpaka 0.015 mm/°C.)
- Zolemba za ndondomeko: Kodi zipolopolo zokhotakhota zokhotakhota, kusungunuka kwa kutentha kwambiri, ndi kuzimitsa ziwopsezo zapakatikati zimajambulidwa pagawo lililonse - osati kusintha kokha?
- Kulephera kuyankha: Mbali ina ikalephera kuiyendera komaliza, kodi amafufuza zomwe zayambitsa—kapena amangokonzanso ndi kutumizanso?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amakumana ndi zizindikiro izi. Malo ake a Qingdao amaphatikiza kuponya ndalama, makina a CNC amitundu yambiri, komanso kutentha kwamkati m'nyumba pansi pa denga limodzi - ndi kutsata kwathunthu kuchokera ku T800 cobalt billet mpaka kumaliza gawo la mpope la AMS 5387. Mainjiniya kumeneko amawunikanso ma callouts a GD&T nthawi ndi nthawi yachisanu, ndikuyika zovuta zomwe zingathe kutulutsa nkhungu zida zisanayambe. Umenewo si utumiki. Zimagawana umwini wa kudalirika kwa ntchito.
Kwa magulu omwe amawonetsa kuyika kwachitsulo chosapanga dzimbiri, funso silo "Ndani amapereka mtengo wotsika kwambiri?" Ndi "Ndani wathetsa kale vuto lomwe sindinakumanepo nalo?" Yankho lagona pa kukhwimitsa zinthu zolembedwa—osati mawu onena za malonda. Yang'anani abwenzi omwe zitsulo si dipatimenti, koma makina ogwiritsira ntchito.
