Kusankha a kuponyera zitsulo zosapanga dzimbiri fakitale sikuti ndikupeza mawu otsika kwambiri. Ndizokhudza kuzindikiritsa mnzanu yemwe amamvetsetsa momwe kulolerana kwa 0.02 mm pampando wa valve kumatanthawuza miyezi 18 ya ntchito yosasokonezeka mumsewu wa hydraulic system. Tawona mapulojekiti ambiri akuyimitsidwa-osati kuchokera ku zolakwika zapangidwe, koma kuchokera ku zosagwirizana zomwe zimangowoneka pambuyo pa chithandizo cha kutentha kapena pakuyesa kukakamiza.
Chifukwa Chake Kuponyera Zitsulo Zosapanga dzimbiri Kumafuna Zambiri Kuposa Kungopezako
Chitsulo chosapanga dzimbiri sichimathiridwa ngati chitsulo chotuwira. Kuchuluka kwake kwa chromium ndi nickel kumawonjezera kusungunuka kwa ma viscosity, kumalimbikitsa mapangidwe a oxide, ndikuchepa mosiyanasiyana panthawi yolimba. Chopangira chodziwikiratu chimatha kukhudza momwe zinthu zimapangidwira - koma kuphonya kufananiza kwapang'onopang'ono, zomwe zimapangitsa kutopa kwanthawi yayitali m'nyumba zozungulira zapampu kapena pobowola m'malo okhala ndi chloride. Pamalo athu ku Qingdao, chitsulo chilichonse chosapanga dzimbiri chimayamba ndi ma AMS 5387-ogwirizana ndi T800 alloy billets - ovomerezeka, owoneka bwino, komanso otsimikiziridwa kale kukula kwa tirigu ndi kuphatikizidwa kusanayambe kusungunuka.
Sitikuwona kuponya ngati sitepe yodziyimira yokha. Ndi gawo loyamba la njira zophatikizidwira zolimba: kuyika ndalama → kuchepetsa kupsinjika → makina olondola a CNC → kutsimikizika komaliza pa Zeiss Contura G2 CMM. Makasitomala akatumiza chojambula cha nyumba ya silinda ya pampu ya piston, mainjiniya athu nthawi yomweyo amawona makulidwe a khoma motsutsana ndi data yofananira - ndi zigawo za mbendera komwe mchenga woponyedwa mumchenga ungatseke porosity. Izi sizongoyerekeza. Mu projekiti ina yaku North America yopangira mafuta, tidagwira utali wa 4.2 mm wamkati wa fillet womwe ukanapanga malo otentha panthawi yoponya ma centrifugal. Kuyipanganso kukhala 6.5 mm kunachotsa kukana pambuyo popanga makina ndi 92%.
Kuphatikizana Kokhazikika Kumathetsa Zowawa Zopanga Zenizeni
Ogula ambiri amatulutsa kuponyera padera ndi makina - kenaka amalimbana ndi ma data olakwika, kupotoza kwa kutentha pakati pa njira, kapena kumaliza kosagwirizana. Timalamulira unyolo wonse. Malo athu ogwirira ntchito ovomerezeka a ISO 9001 amakhala ndi ng'anjo zopangira ng'anjo zosapanga dzimbiri komanso makina a nickel a cobalt-nickel *ndi * 5-axis DMG MORI makina otha kumaliza malo oponyedwa mkati mwa ± 0.015 mm osakonzanso.
Kuphatikiza uku kumapereka maubwino atatu oyezeka:
- Dimensional bata: Kuponyedwa kumayendetsedwa ndi kuzizira koyendetsedwa mu nkhungu zotsekedwa, kenaka kuchepetsa kupanikizika pa 1050 ° C musanagwiritse ntchito movutikira-kuchepetsa kupanikizika kotsalira ndi 70% poyerekeza ndi machitidwe a mpweya wozizira.
- Umphumphu pamwamba: Palibe kuphulika kwachiwiri kapena pickling ya asidi yomwe ikufunika isanathe. Magawo athu osapanga mchenga amakwaniritsa Ra ≤ 3.2 µm ngati-cast; kuponyedwa kwa ndalama kumafika ku Ra ≤ 1.6 µm-yokonzeka kuti iwonongeke kapena electropolishing.
- Kukonzekera kogwira ntchito: Ma valve opanikizika amatumiza ndi malipoti a hydrostatic test, logs test test, and GD & T-compliant inspection dossiers-osati ma checklist a dimensional.
Pamene Zida "Zokhazikika" Zikafupika—Ndipo Zoyenera Kuchita M'malo mwake
Mainjiniya ena amafikira 316 osapanga chilichonse. Koma muzovala zapamwamba-monga zodzigudubuza za winch center shaft pamagalimoto akumigodi-316 imakhala yopanda kuuma komanso kulimba kwamphamvu. Nthawi zambiri timalowetsa m'malo mwa 17-4PH H900 kapena AMS 5387 cobalt alloy, kutengera kuchuluka kwa katundu komanso kutentha.
Pampu ya ku Europe ya OEM idaumirirapo 304 kuti ikhale ndi ma valve oziziritsidwa ndi madzi am'nyanja. Ma prototypes awo adalephera kuyesa kupopera mchere pambuyo pa maola 320. Tinaganiza zosinthira ku F51 duplex yosapanga dzimbiri-njira yoponyera yomweyi, nkhungu yomweyi, koma 22% yapamwamba PREN (Pitting Resistance Equivalent Number). Gawo losinthidwalo ladutsa kuyesa kwa maola 2,000 ndi zero pitting. Mtengo wakwera ndi 14%. Kutalika kwa moyo ndi 4.7 ×. Kusinthanitsa kumeneko? Zolembedwa m'mabuku awo okonza zinthu.
Momwe Kuperekera Kodalirika Kumawonekera
“Kupereka pa nthawi yake” kumatanthauza zinthu zosiyanasiyana. Kwa oyang'anira zogula, ndi tsiku la kalendala. Kumagulu a utumiki wakumunda, kumakhala ndi mbali yeniyeni yoloŵa m’malo—yotenthedwa, yopendedwa, ndi kulembedwa chizindikiro—pamene chotchingacho chazimitsa. Timatseka mawindo obweretsera panthawi yowunikira uinjiniya, osati pambuyo potsimikizira. Kuyenda kwathu kowonda kumaphatikizapo nthawi ya buffer yotsimikizira zitsulo, osati kungokonza makina.
Pazinthu zoyitanitsa, nthawi yotsogolera imayamba *pambuyo* kutsimikizira kwa GD&T—osati chiphaso cha PO chikachitika. Pamayendedwe apakati (ma PC 50-500), timasunga zinthu zopangira magiredi wamba (316L, F22, 17-4PH) ndipo timakhala ndi mapeni 12 omwe amafunsidwa kwambiri - kuphatikiza ma valve oponderezedwa, maziko a pampu, ndi ma silinda. Izi zimachepetsa nthawi zobwereza-bwereza ndi 35% pafupifupi.
Ngati mukufuna a kuponyera zitsulo zosapanga dzimbiri fakitale zomwe zimagwira gawo lanu ngati dongosolo lofunikira kwambiri - osati gawo lazamalonda - zimayamba ndi kutsatiridwa kwa zinthu, zimafuna kuwongolera njira zophatikizika, ndikutsimikizira momwe zimagwirizira kusiyana pakati pa kutsimikizika ndi zochitika zenizeni padziko lapansi. Wokondedwa woyenera sadzangotsanulira zitsulo. Iwo amayembekezera komwe mapangidwe anu amakumana ndi fiziki - ndi kukuthandizani kuti musinthe.
