Pamene mainjiniya amatchula a kuponya maziko pazigawo zazitsulo zolondola, sikuti amangoyitanitsa zitsulo-akudzipereka kuti azikhala okhazikika pansi pa 300 bar pressure, microstructure integrity pambuyo pa kutentha kwa njinga, ndi zero kulolerana kwa porosity mumphuno ya cobalt alloy. Ndicho chenicheni chomwe timachiwona tsiku ndi tsiku ku Qingdao Qiangsenyuan Technology Co., Ltd-wopanga kumene "kulondola" sikuli chinenero cha malonda. Ndizofunikira zochepa zomwe zimasindikizidwa pa lipoti lililonse loyendera.
Chifukwa chiyani zisankho za Casting Foundry Zimalephera Machining Asanayambe
Tawunikanso zithunzi zopitilira 180 zamakasitomala chaka chatha—ndipo 63% inali ndi mikangano yobisika mu GD&T callouts. Chitsanzo chodziwika bwino: kufotokozera ± 0.05 mm malo enieni pa maziko a mpope a mchenga wa 420 mm, pamene akufunikira AMS 5387 cobalt alloy ndi Rm ≥ 1,250 MPa. Kuphatikizika kumeneku kumafuna kukhazikika koyendetsedwa, kuziziritsa kolowera, komanso mpumulo wapambuyo-pa-palibe omwe masitolo okhazikika amawunika momwe akuchitira. Chotsatira? Warpage pakumalizidwa komaliza kwa CNC, magulu odulidwa, ndi kuchedwa kwa kutumiza komwe kumadutsa mizere ya msonkhano wa OEM.
Kukonzekera kumayambira pamwamba. Pamalo athu ogwirizana ndi ISO ku Qingdao, kuponya sikungochitika zokha—ndi mfundo yoyamba motsatizana molimba mtima: kapangidwe kake → kayesedwe ka nkhungu → kutsimikizira batch yazitsulo → kuwunika kwamafuta → CMM yotsimikizika ngati geometry. Timayendetsa ma model olimba pa gawo lililonse latsopano, kuyika malo otentha asanayambe kuthira koyamba. Kwa nyumba za silinda ya pampu ya piston, izi zikutanthauza kusintha geometry kuti athetse kuchepa kwa valavu zone-kuchepetsa kukonzanso kuchoka pa 12% kufika pansi pa 2%.
Kumene Ma Aloyi a Cobalt Amalekanitsa Zoyambira Zenizeni Kwa Ogulitsa
Zigawo za Cobalt-nickel-makamaka AMS 5387 ndi T800 giredi-amawulula mipata ya kuthekera mwachangu. Ma alloys awa samangokana dzimbiri; amakana machining, amakana kufanana kwa chithandizo cha kutentha, ndi kukana mankhwala osagwirizana ndi ogulitsa. Timapeza zinthu zopangira kuchokera ku mphero zokhala ndi traceability yokwanira ya ladle ndipo timasanthula OES pa koyilo iliyonse yomwe ikubwera. Koma chemistry yokha sichitsimikizira ntchito. Mu pulojekiti ina yaposachedwa, European hydraulic OEM idanenanso kuti mapulagi a aloyi a cobalt asanakwane. Ndemanga yathu yazitsulo idavumbulutsa kuti gwero lake silinapangidwe - kunali kupangika kosalamulirika kwa delta ferrite panthawi yolumikizira yankho. Tidasintha nthawi yonyowa komanso kuzizira, kenako kutsimikiziridwa ndi mapu a SEM/EDS. Kukana kwa Crack kumayenda bwino ndi 300% pakuyesa kogwira ntchito.
Ichi ndichifukwa chake kuphatikiza koyima ndikofunikira. Mukaponya, kutentha, ndi makina a 5-axis zimachitika pansi pa denga limodzi, mumawongolera zosintha zomwe zimatanthauzira kudalirika: momwe mayendedwe ambewu amayendera potengera njira zonyamula, kugawanika kotsalira kotsalira musanadulidwe komaliza, ndi kukhulupirika kwapamtunda pambuyo pa kuwomberedwa. Kwa makina opangira ma winch center shaft rollers, izi zikutanthauza kugwirizanitsa kukula kwa dendrite mofanana ndi torque axis - ndikutsimikizira ndi ultrasonic anisotropy scans.
Kodi “Kulondola” Kumatanthauza Chiyani Kwenikweni Pochita
Kulondola si nambala pajambula. Ndi momwe mumagwirizira 0.025 mm makulidwe a khoma kudutsa 270 ° ya thupi la valve yokakamiza. Imakwaniritsa Ra ≤ 0.8 µm pa ndime zamkati popanda kupukuta kwachiwiri. Ikupereka zokolola zoyamba 98% pazithunzi zomwe sizili wamba ngati ma nozzles a cobalt okhala ndi zigawo za khoma la 0.3 mm.
- Dimensional control: Kufotokozera kwathunthu kwa CMM pazinthu zonse zovuta, ndi malipoti odzichitira okha ogwirizana ndi miyezo ya ASME Y14.5
- Kutsimikizira kwazinthu: Ziphaso zotsimikizika za gulu, kuphatikiza kulimba, mphamvu, ndi kuyesa kwa intergranular corrosion test
- Kutsimikizira kogwira ntchito: Kuyesa kukakamiza kwa 1.5 × kukakamiza kugwira ntchito, kuphatikiza utoto wolowera kapena UT m'malo onse opsinjika kwambiri
- Kutsata: Ma ID okhala ndi laser olumikizidwa ndi zipika zosungunula, ma chart a kutentha, ndi zolemba zoyendera
Sitimapereka chilichonse mwa izi. Kupanga chitsulo chilichonse, chitsulo chopanga zitsulo, ndi zitsulo zosapanga dzimbiri zimadutsa mu labu yathu yathu yabwino—osati mndandanda wa ofufuza wa gulu lina.
Kusankha Kupitilira Mtengo: Chomwe Chotsimikizika Chotumizira
Kutsika kwamitengo sikuwonetsa kuopsa. Mtengo wa $28/kg popanga zitsulo zosapanga dzimbiri umawoneka wokakamiza mpaka mutadziwa kuti shopuyo ilibe mphamvu zogulira ndalama komanso kupanga ma cores ovuta. Izi zimawonjezera nthawi yotsogolera masabata atatu ndikuyambitsa kulephera kwa mawonekedwe. Ku Qingdao Qiangsenyuan, nthawi yopangira ma prototype mpaka kupanga ndi yodziwikiratu chifukwa ndife eni ake zida, ng'anjo, ndi makina oyezera. Pamadongosolo apakatikati (ma PC 50-500), kuyenda kwathu kowonda kumapereka mkati mwa masiku ± 5 amasiku odzipereka - otsimikiziridwa kudutsa 217 kutumiza chaka chatha.
Kudziwikiratu kumeneko kumachokera ku mgwirizano wopangidwa mwaukadaulo. Sitikuyembekezera kuti zojambulazo zikhale "zomaliza." Tikamawunikiridwa koyambirira, gulu lathu limawonetsa zovuta za kupanga: ma angles osazama kwambiri kuti apangire mchenga, ma radiyo othina kwambiri kuti asachotsedwe, kapena masikimu a GD&T omwe amasemphana ndi machulukidwe opumira. Wopanga pampu wina waku North America adachepetsa mayendedwe ake ndi 40% atatengera njira yowunikirayi.
Kwa ogula mafakitale omwe amapeza zigawo zazitsulo zolondola, kumanja kuponya maziko sichimatanthauzidwa ndi masikweya makwerero kapena matani apachaka. Zimatanthauzidwa ndi momwe zimamvetsetsera mozama njira zanu zolepherera - komanso momwe zimakhalira zimamangirira kupewa mu sitepe iliyonse. Kaya mukufuna ma valve okakamiza okhala ndi mipiringidzo 400, zigawo 6 zapampu za cobalt zomwe zatsala pang'onopang'ono, kapena ma geometries a T800 omwe amafunikira mphamvu ndi kutha kwa makina - timayamba ndi momwe zinthu ziliri komanso mainjiniya abwerera mmbuyo. Kulondola kumayambira pomwe malingaliro amatha.
