Pamene mainjiniya afotokoza 2Cr13 chitsulo chosapanga dzimbiri kwa matupi a hydraulic valve, pisitoni pampu yanyumba, kapena zodzigudubuza za winch center shaft, samangosankha zakuthupi - akubetcha pamlingo wokhazikika pansi pa 300+ bar pressure, kukana kugunda m'malo otsetsereka, komanso kuuma kosasintha pambuyo pa chithandizo cha kutentha. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni 2Cr13 fakitale yachitsulo chosapanga dzimbiri-osati wotsatsa malonda kapena zopangira zonse - sizingakambirane. Tawona mapulojekiti ambiri akuchedwa chifukwa cha kulimba kwamphamvu kosagwirizana (Rm), kusagwirizana kwa HRC 28-32 kupsya mtima, kapena ma microcracks akuwululidwa panthawi yoyeserera.
Chifukwa chiyani 2Cr13 Imafunikira Zambiri Kuposa Kukonza Kwazitsulo Zosapanga dzimbiri
2Cr13 siyabwino ngati 304-ndi martensitic. Izi zikutanthauza kuti kagwiridwe kake kamene kamatengera mbiri yakale yamafuta: kukhazikika pa 980-1050 ° C, kuzimitsa mafuta, kenako kutenthetsa pakati pa 600-750 ° C kugunda kulimba kwa chandamale popanda kusiya kulimba. Wopereka ma generic atha kubweretsa "2Cr13" yomwe imakumana ndi ma chemistry a GB/T 1220 - koma amalephera pamakina. Tayeza magulu omwe mphamvu zokolola zimasiyanasiyana ± 45 MPa m'malo ambiri chifukwa cha kuzizirira kosalamulirika kapena nthawi yosakwanira yonyowa. Zotsatira zadziko lenileni? Nyumba ya silinda idasweka pakupalasa njinga pamtunda wa 220 bar - osati powotcherera, koma m'malo omwe amakhudzidwa ndi kutentha.
Apa ndipamene kuphatikiza koyima kumafunika. Pamalo athu a Qingdao, timawongolera unyolo wathunthu: certified billet sourcing (ndi malipoti oyesa mphero omwe amatsatiridwa ndi nambala ya ng'anjo), makina a CNC otsimikizira kuuma kwa mkati, mavuvu otenthetsera othandizidwa ndi vacuum okhala ndi ± 3 ° C, ndikuwunika komaliza kwa CMM motsutsana ndi ma callout a GD&T - osati mwadzina chabe. Palibe ma handoffs. Palibe kulosera kwa batch-to-batch.
Maluso Anayi Omwe Amalekanitsa Fakitale Yowona ya 2Cr13 Yazitsulo Zosapanga dzimbiri ndi Zina
- Metallurgical chilango: Timatsimikizira kutentha kulikonse kwa 2Cr13 pogwiritsa ntchito spark spectrometry pre-machining-ndikuyesanso kutentha kwapambuyo pa kutentha kuti titsimikizire kusunga kaboni ndi kukhazikika kwa chiŵerengero cha Cr/Mn. Magawo a AMS 5387 cobalt alloy amagawana momwe amagwirira ntchito labu, kotero kusasinthasintha kwazinthu sizongopeka.
- Machining-kutentha mankhwala synergy: Ma cell athu a CNC amitundu yambiri amakhala ndi ng'anjo zotentha. Magawo amapita molunjika kuchokera kumapeto mpaka kupsya mtima—palibe kuzizirira komwe kumayambitsa kusokonezeka kotsalira. Zotsatira: pisitoni mpope housings kugwira ≤0.015 mm kuzungulira kulolerana pa Ø180 mm, ngakhale pambuyo maola 500 kutsitsi mchere.
- Kukonzekera komaliza kogwira ntchito: Pa ma valve opanikizika, timayika nitriding yoyendetsedwa - osati plating yachibadwidwe - kuti tilimbikitse kulimba kwa HV 900+ ndikusunga kulimba kwapakati. Pazitsulo za winch, timagwiritsa ntchito kugaya molondola ndi kuyang'anitsitsa nthawi yeniyeni ya roughness (Ra ≤0.4 μm) kuti tipewe kusindikiza msanga.
- Traceability yowotchera, osati yotsekeredwa: Chigawo chilichonse cha 2Cr13 zombo zokhala ndi satifiketi ya digito yowonetsa zinthu zambiri, piritsi lamankhwala otentha, chithunzithunzi cha lipoti la CMM, ndi ID ya ogwiritsa ntchito. Osati “zotsatira”—zomveka.
Mtengo Wosankha Molakwika—Ndi Zomwe Zimawonongadi Kuti Uzikonze Bwino
Ogula ena amathamangitsa mtengo wotsika wa unit. Kenaka amatenga ndalama zitatu zobisika: kukonzanso (tinawona 22% mlingo wa zidutswa za 2Cr13 kuchokera m'masitolo osavomerezeka chifukwa cha decarburization), kulephera kwamunda (msonkhano umodzi wa valve wogwidwa mu zida za mafuta a m'mphepete mwa nyanja ukhoza kuwononga $ 17k / ora kutsika kwa ola), ndi kuchedwa kwapangidwe kobwerezabwereza (mayankho ovomerezeka a GD & T amatenga maola 72 apa).
Mitengo yathu ikuwonetsa zomwe zimawononga kuti tichite 2Cr13 kumanja: chiwongola dzanja chotsimikizika (chosagonja), chida chodzipatulira cha makina olimba kwambiri (zoyika za carbide zokhala ndi zokutira za PVD TiAlN), komanso kuwunika kwa tinthu tating'ono 100% pamagawo ovuta. Koma makasitomala amatiuza mosalekeza kugunda kwa ROI pamlingo wofananira-pamene mayunitsi awo 5 oyambilira apambana mayeso anthawi yake, palibe kuyesa kachiwiri kofunikira.
Kuyang'ana M'tsogolo: Kumene Kupanga kwa Precision 2Cr13 Kukupita
Ntchito za m'badwo wotsatira zimafuna kulumikizana kolimba pakati pa kukhulupirika kwa kuponyera ndi geometry yamakina. Tsopano tili oyenerera njira zosakanizidwa: ma cores-cast 2Cr13 cores okhala ndi zololera zamtundu wapafupi (± 0.3 mm), kutsatiridwa ndi ma axis asanu ozungulira kuti akwaniritse makulidwe a khoma mpaka 4.2 mm-popanda kusokoneza moyo wotopa pazozungulira 10⁷. Nthawi yomweyo, gulu lathu la R&D likutsimikizira ma prototyping ofulumira a ASTM A957 a 2Cr13, ndikudula nthawi yotsogolera kuyambira masabata 12 mpaka masiku 18 kwa ma geometri oyenerera.
Ngati ntchito yanu ikufuna chitsulo chosapanga dzimbiri cha 2Cr13 chomwe chimagwira ntchito-osati kungodutsa zolemba-mufunika mnzanu yemwe amawona zitsulo monga uinjiniya, osati kugula. Izi zimayamba ndikufunsa mafunso oyenera: Kodi mungandiwonetseko kutentha kwa mwezi watha? Kodi malipoti anu a CMM akuphatikizanso data ya chipukuta misozi? Kodi kutsatiridwa kwanu kwazinthu kumalumikizidwa ndi zipika za ng'anjo-kapena nambala chabe?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga mayankho amenewo mu gawo lililonse. Chifukwa mu machitidwe apamwamba, palibe "zabwino zokwanira" zitsulo zosapanga dzimbiri.
