Mainjiniya akamatchula zitsulo zovuta, zodalirika kwambiri zama hydraulic system kapena mafuta & gasi, nthawi zambiri samayamba ndi "kutaya thovu." Amayamba ndi vuto: nyumba ya valve yomwe imatsika pansi pa 400 bar, silinda ya pampu ya piston yokhala ndi ming'alu yaying'ono pambuyo pa njinga yamoto yotentha, kapena cholozera cha winch center shaft roller chikulephera msanga m'malo owopsa akunyanja. Ndipamene kutayika kwa thovu kutayika sikukhala njira yokhayo-koma yankho lokhalo lotheka. Ndipo ndiye a fakitale yotaya thovu ndi chilango chozama chazitsulo ndi kuwongolera ndondomeko yophatikizana kumapangitsa kusiyana.
Kutaya thovu sikumangoponya mchenga ndi thovu. Ndi wosakanizidwa bwino wochotsa-wowonjezera: mawonekedwe a EPS opangidwa ndi CNC amakutidwa, kukwiriridwa mumchenga wa silika wosamangika, kenako amatenthedwa * mu situ* ndi chitsulo chosungunuka. Palibe mizere yolekanitsa. Palibe ma cores oti asinthe. Palibe ma angles omwe amalepheretsa geometry. Koma kupambana kumadalira pa zinthu zitatu zomwe sizingakambirane - kukhazikika kwachitsanzo panthawi yopaka, kuwongolera bwino kwa metallostatic panthawi yothira, ndi kuyang'anira nthawi yeniyeni ya kutentha kuti musachepetse porosity mu zigawo zokhuthala. Tawona makasitomala akusintha kuchoka pakupanga ndalama kupita ku thovu lotayika la AMS 5387 cobalt alloy pampu - ndikudula nthawi yotsogolera ndi 37% kwinaku akuwongolera kumveka kwamkati. Chifukwa chiyani? Chifukwa katundu wawo m'mbuyomu ankachitira thovu ngati zotayidwa. Athu amachitenga ngati gawo loyamba lolondola mu unyolo.
Ambiri fakitale yotaya thovu Ogwiritsa ntchito amayang'ana kwambiri pa voliyumu kapena kuphweka-zikuluzikulu zazitsulo zazitsulo, mabatani oyambira, zitsulo zotsika. Ochepa akugwira T800 cobalt-based alloys kapena mipanda yopyapyala, yotalikirana kwambiri yomwe imafuna ± 0.15 mm dimensional kubwereza kutalika kwa 200 mm. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timapanga makina a thovu pa 5-axis CNC malo-osati chifukwa ndi chonyezimira, koma chifukwa kupatuka kwa 0.08 mm pamatanthauzidwe kumasulira mwachindunji ku 0.12 mm kuchotsera pamalo omaliza opangidwa ndi makina pambuyo pa kugwedeza ndi kutentha. Malo athu ogwirizana ndi ISO amayendera ntchito zofananira: mzere umodzi woperekedwa ku ma aloyi a cobalt-nickel (AMS 5387, L-605), winanso wokongoletsedwa ndi zitsulo zosapanga dzimbiri za ferritic zomwe zimagwiritsidwa ntchito pamaziko a pampu wowawasa-gasi. Mzere uliwonse uli ndi malo ake omwe amawongolera chinyezi, ng'anjo yowotchera kale, ndi malo othira othandizidwa ndi vacuum omwe ali ndi ± 2.5 kPa.
Izi ndi zomwe zimalekanitsa kuphedwa kodalirika ndi kuthekera kwamalingaliro:
- Kufufuza kwazinthu kumayamba kusanasungunuke: Billet iliyonse ya T800 imabwera ndi chemistry yotsimikizika ya kutentha, kukula kwa tirigu, ndi malipoti olimba - osati ma cert a mphero okha. Timayesanso zinthu zomwe zikubwera za Co, Cr, Ni, W, ndi C pogwiritsa ntchito OES, kenako timagawira ma ID apadera omwe amalumikizidwa ndi gawo lililonse loponyera.
- Palibe "bokosi lakuda" kumaliza: Pambuyo pa kugwedezeka, chitsulo chilichonse kapena chitsulo choponyera chitsulo chimakhala chochepetsera nkhawa pa ASTM A781, ndikutsatiridwa ndi kuyang'anitsitsa kwa akupanga (ASTM E186) pazigawo zovuta. Ziwalo za cobalt zimapita molunjika ku yankho la anneal + kuzimitsa mwachangu-popanda kuziziritsa mpweya, palibe kusinthasintha.
- Machining sikutsika pansi - amapangidwa pamodzi: Makasitomala akatumiza chojambula cholemera cha GD&T cha valavu yamagetsi, mainjiniya athu samangotchula makina. Amatsanzira kulimba mu MAGMAsoft, malo okwera mbendera omwe amasokoneza malo omaliza a data, ndipo amalingalira zosintha zomwe zimachotsa kukonzanso kwachiwiri - kupulumutsa $ 18.40 pa gawo lililonse pamlingo wapakatikati.
Ena amanena kuti chithovu chotayika sichingafanane ndi kumalizidwa kwa ndalama. Zowona - pamapulogalamu a Ra 0.8 µm, sizitero. Koma pazida zogwirira ntchito zomwe zitha kugwedezeka kapena kugwedezeka? Chithovu chotayika chimapereka kufanana kwapamwamba kwa microstructural m'magawo olemera. Tinayeza kulimba kwa 12% pakhoma la 65-mm-thick AMS 5387 silinda ya nyumba motsutsana ndi ndalama zofananira nazo - zomangika pang'onopang'ono, zolimba kwambiri mumchenga wosasunthika. Kusasinthika kumeneku kumafunika pamene chitsimikizo cha mpope cha kasitomala wanu chimadalira moyo wotopa pa 10⁷ cycle.
Ngati mukuyesa a fakitale yotaya thovu, funsani mafunso atatu musanawunikenso mawu: Kodi angatsimikizire kukhazikika kwa mawonekedwe pambuyo pakuyala ndi kuyanika? Kodi amalowetsa kutentha, vacuum level, ndi mutu wa metallostatic kutentha kulikonse? Ndipo—mofunikira—kodi amakhala ndi zowunikira zomaliza pazochita zilizonse, osati maere chabe? Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., amenewo si mabokosi. Iwo amachita tsiku ndi tsiku. Tatumiza zoposa 1,200 za cobalt ndi zitsulo zosapanga dzimbiri ku North America OEMs kuyambira 2021-zonse zili ndi malipoti athunthu a CMM, mitengo yothira kutentha, komanso kufufuza zinthu kubwerera ku ingot. Osati chifukwa ndi zophweka. Chifukwa mbali zofunika kwambiri za utumwi sizisiya malo amalingaliro.
Tsogolo la kuponya mwatsatanetsatane silikhudza kusankha pakati pa njira-ndizofanana ndi kufananiza koyenera kwa hybrid ndi ntchito ya gawolo. Chithovu chotayika cha kukhulupirika kwa mawonekedwe apafupi. CNC yowongolera magwiridwe antchito. Chithandizo cha kutentha kwa microstructure kukhulupirika. Kumaliza kwa mawonekedwe a mawonekedwe. Kuphatikizika kumeneko-kupangidwa, kuchitidwa, ndi kutsimikiziridwa ngati kachitidwe kamodzi-ndiko komwe kumasintha ndondomeko yoponyera kukhala gawo lotsimikiziridwa ndi munda. Kwa mainjiniya atopa ndi kuthamangitsa mitengo yazinthu, kuchedwa kubweretsa, kapena zitsulo zosagwirizana, sitepe yotsatira si RFQ ina. Ndikuwunikanso kwaukadaulo ndi mnzanu yemwe amachitira thovu ngati zida zolondola, cobalt ngati chosinthika chodziwika bwino, komanso nthawi yanu ngati nthawi ya mgwirizano.
