Pamene mainjiniya amatchula a fakitale ya shaft yowongoka, sikuti amangopeza chinthu chozungulira - akusankha bwenzi lomwe lingathe kupirira ± 0.005 mm pansi pa 300 MPa hydraulic loads, kukana kuphulika m'malo otsekemera, ndikupereka kutsata kwazinthu zonse mpaka kutentha. Mlingo woterewu suchokera kawirikawiri m'masitolo ogulitsa zitsulo.
Tawonapo mapulojekiti ambiri akuyimitsidwa pamlingo wofananira chifukwa shaft-yopangidwira kuti ikhale yothamanga kwambiri pamakina oyesera pampu yapakati-yopindika panthawi ya kutentha. Kapena kulephera kuyesa kugwedezeka pambuyo pa maola 42 chifukwa chosazindikirika cha micro-porosity pachimake choponya. Izi sizowopsa zongoyerekeza. Ndi mitundu yolephera yobwerezabwereza yomwe tapeza m'makontinenti atatu, m'makina opangira mafuta, ma hydraulic actuators apanyanja, ndi mapampu amphamvu kwambiri amankhwala.
Kulondola kumayambira pomwe zitsulo zimakumana ndi geometry
Wowongoka shaft si silinda wamba. Ndi mawonekedwe ogwira ntchito: mapeto amodzi ndi mpikisano wolondola; gawo lapakati limanyamula mano olimba a spline omwe amatumiza torque pomwe amalumikizana molakwika; ulusi womwewo umakhala wolumikizana mozungulira mozungulira. Kupatuka kulikonse pakukhazikika, kutha kwa pamwamba (Ra ≤ 0.4 µm), kapena kugawanika kotsalirako kumafalikira ngati phokoso, kuvala, kapena kutopa kowopsa.
Ndicho chifukwa chake kusankha zinthu sikungathe kutumizidwa kunja kwa deta. Cobalt-nickel alloys ngati AMS 5387 amapereka kukana kwa dzimbiri ndi kuuma kotentha-koma ama makina pa 1/3 mlingo wa chakudya cha 4140 zitsulo ndipo amafuna kukhazikitsidwa kolimba, zida za cryogenic, ndi kuyang'anira nthawi yeniyeni ya kutentha. T800-based shafts imafuna kuponyedwa kwandalama ndi zipolopolo za ceramic, kutsatiridwa ndi HIP (hot isostatic pressing) kutseka ma voids amkati-kenako CNC kuyatsa makina okhala ndi sub-micron axis positioning. Kudumpha sitepe iliyonse kumasokoneza kukhulupirika.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timawona shaft iliyonse ngati mfundo yofunika kwambiri - osati gawo lazamalonda. Malo athu ogwirizana ndi ISO ku Qingdao amaphatikiza kuponyera, makina amitundu yambiri, komanso kumaliza pansi padenga limodzi. Palibe ma handoffs. Palibe kusamutsidwa kwamagulu. Makasitomala akatumiza zojambula za GD&T zautali wa 320 mm, shaft ya 65 mm m'mimba mwake yokhala ndi 12 ° helical splines ndi kuzama kwa milandu ya HRC 58-62, gulu lathu limatsimikizira kuthekera kopanga * tisanatchule mawu - kuyika madera omwe angakambidwe, ndikulimbikitsa kutsata njira yoyenera, ndikutsimikizira kusinthasintha kwa kutentha kwa gawo lozungulira.
Kuphatikizika koyima sikuli kothandiza-ndikuwongolera
Otsatsa ena amaponya zinthu zakunja, kenako kukonza makina opangira ma subcontract, kenako amatumiza magawo kumashopu agulu lachitatu. Chigawo chilichonse chimayambitsa kusiyanasiyana: kapangidwe ka tirigu kosagwirizana ndi machitidwe osatsimikizika, kusuntha pang'onopang'ono kuchoka pakukonzanso, kuipitsidwa pamwamba musanagaye chiphaso chomaliza. Tayesa mpaka 18 µm kuthamanga kwapakati pakati pa zoponya zomwe zikubwera ndi ma shaft omalizidwa pamene njira zagawika.
Mayendedwe athu ophatikizika ophatikizika amachotsa mipata iyi:
- Kuponya m'nyumba: Mchenga ndi mizere yopangira ndalama zopangira ma aloyi a cobalt - osadalira zopangira zakunja zokhala ndi mbiri yamoto wamba
- Makina pazida zolembetsedwa: 5-axis CNC malo okhala ndi zida zamoyo, ma probe a Renishaw, ndi kutsimikizira kwa CMM mkati mwama diameter ovuta
- Kumaliza ndi cholinga: Zovala za nickel zopanda ma elekitirodi kuti musavulale, kuwomberedwa chifukwa chopanikizika kwambiri, kapena kupukuta pagalasi pamawonekedwe osindikizira - kumagwiritsidwa ntchito pokhapokha ngati ntchito ikufuna
Izi sizokhudza kuchepetsa mtengo. Ndizokhudza kuchotsa zosinthika zomwe zimawononga kubwerezabwereza. Shaft yopangidwa pamakina omwe sanayesedwe ndi laser m'miyezi 9 akhoza kukumana ndi zosindikizira lero - ndikulephera kufufuza mawa. Timakonzanso maola 72 aliwonse opanga. Malo aliwonse otenthedwa ndi kutentha amatsimikizira Brinell ndi Rockwell. Shaft iliyonse yomalizidwa imapeza 100% kuyang'ana kowoneka bwino kwa zolakwika zapamtunda ndi kutsimikizika kwa CMM motsutsana ndi mtundu woyambirira wa CAD.
Chifukwa chiyani zolemba za "standard" sizikugwira ntchito pamitu yofunikira kwambiri
"Ingofikani ku ASTM A494 Grade M35-1" - pempholi silitiuza chilichonse chokhudza envelopu yanu yeniyeni. Kodi shaft iyi ikuzungulira 4,200 RPM mkati mwa subsea valve actuator? Kodi imayendetsa maulendo 12,000 pa sabata mu sitima yapamtunda yosakaniza simenti? Kodi idzawona kuwonetseredwa kwakanthawi ndi H₂S kapena madzi am'nyanja okhala ndi chlorinated?
Timafunsa mafunso amenewo-osati chifukwa timasangalala ndi mapepala, koma chifukwa yankho limasintha chirichonse: kusankha kalasi ya zinthu, kutentha kutentha kutentha nthawi, njira yoyesera yosawononga (UT vs. MPI), ngakhale phukusi lolongedza (vapor-phase inhibitors kuti atumize kunja). Pampu imodzi yaku Europe ya OEM idaphunzira izi movutikira: shaft yawo yachitsulo chosapanga dzimbiri "yokhazikika" idachita dzimbiri mkati mwa milungu itatu mu jekeseni wa brine. Kusintha kupita ku AMS 5387 yokhala ndi kubalalitsidwa koyendetsedwa ndi carbide kumawonjezera moyo wautumiki mpaka miyezi 18.
Kusintha kumeneko sikunali matsenga. Zinachokera pakuwunikanso kwaumisiri wolumikizana - komwe tidapanga mapu a kulephera kwawo, kuchuluka kwa magwiridwe antchito a alloy kuchokera ku NACE MR0175, ndikutsimikizira zatsopanozi kudzera pakuyesa moyo mwachangu mu labu yathu.
Yang'anani kupyola pa kujambula—yang’anani pa mwambo wopereka
Shaft yabwino mwaukadaulo sikutanthauza kanthu ngati ifika mochedwa milungu iwiri kuti itumizidwe. Kapena mayunitsi 10 oyambilira akadutsa pakuwunika, koma ya 11 ikulephera chifukwa chakuyenda kosalemba. Timakhazikitsa njira zowongolerera zogwirira ntchito: Kuyika kwazinthu zoyendetsedwa ndi Kanban, kuyitanitsa ntchito zotsatizana ndi zoyang'anira zophatikizika za QC, ndi ma dashboards opanga nthawi yeniyeni omwe makasitomala amapeza.
Pamayendetsedwe a ma prototype, timatumiza malipoti ankhani yoyamba okhala ndi data yonse ya metrology-kuphatikiza logi zachipukuta misozi. Pamaoda apakati, timakhala ndi ma buffer stock of certified billets kuti titenge kugwedezeka kwa supply chain popanda kusokoneza mtundu wa zinthu.
Ngati mukufuna a fakitale ya shaft yowongoka amene amaona kukhazikika kwa dimensional monga zosakambitsirana, kusasinthasintha kwazitsulo monga kovomerezeka, ndi kutumiza pa nthawi yake monga umboni wa ndondomeko ya ndondomeko-kuyamba ndi kukambirana ndi luso, osati ma RFQs. Pitani ku https://www.tsingtaocnc.com kuti muwunikenso zidziwitso za kuthekera, ziphaso zazinthu, ndi chidule cha zochitika zenizeni padziko lapansi. Shaft yomwe mumatchula lero idzatanthauzira kudalirika kwadongosolo kwa zaka. Sankhani moyenerera.
