Utumiki woponya mchenga si njira ya cholowa chabe-ndi msana wa zigawo zachitsulo zolimba, zofunikira kwambiri. Pamene ma hydraulic mavavu amayenera kusindikiza pa bar 350, pomwe ma winch center shaft rollers amapirira kugwedezeka kwatsiku ndi tsiku pamagalimoto ainjiniya, kapena ma nozzles a cobalt alloy alloy akugwira ntchito mosalekeza m'malo owononga mafuta ndi gasi, kuponyera mchenga kumapereka zomwe njira zina sizingatheke: kukhazikika kwapang'onopang'ono m'magawo akulu, kulimba kwazitsulo zolimba, kulimba kwachitsulo komanso kulimba kwazitsulo. kupanga kwapakatikati. Tapanga nyumba zopitilira 12,000 zachitsulo ndi zitsulo kuyambira 2019-chilichonse chimatsimikiziridwa motsutsana ndi ASME B16.34 ndi ASTM A27/A668 makina opangira makina asanayambe.
Chifukwa Chake Kuponyera Mchenga Kumapambanabe Pazigawo Zamagulu a Industrial-Grade
Ena angatsutse kuti kuponya ndalama kapena kufa kumaposa kuponya mchenga pamtunda kapena kuwongolera kulolerana. Koma muzochita zenizeni padziko lapansi, makamaka magawo opitilira 25 kg okhala ndi makulidwe a khoma pamwamba pa 25 mm - kuponya mchenga sikungafanane. Imagwira matenthedwe misa popanda kusweka. Imakhala ndi ma cores ovuta amkati olowera ndime mu nyumba za silinda pampu ya piston. Ndipo imavomereza zipangizo zamtundu wapamwamba monga AMS 5387 cobalt alloy ndi T800-grade superalloys popanda kukokoloka kwa nkhungu kapena kufa msanga. Pa malo athu ovomerezeka a ISO 9001 ku Qingdao, timagwiritsa ntchito mchenga wa silika wopangidwa ndi utomoni wokhala ndi utomoni wogawira tirigu-osati mchenga wobiriwira-kuti tikwaniritse kuuma kobwerezabwereza (Ra ≤ 12.5 µm) ndi kuchepetsa ma microfractures okhudzana ndi shakeout ndi 40% motsutsana ndi kuumba wamba.
Tawona makasitomala akutaya masabata-ndi zikwi zambiri pokonzanso-posankha njira zofulumira koma zosakhululuka. Pampu imodzi yaku North America OEM inasintha kuchoka ku aluminiyumu yakufa-cast kupita ku chitsulo chosapanga dzimbiri 316 kuti ikhale ndi ma valve opanikizika pambuyo pakulephera katatu. Chifukwa chake? Kutentha panjinga kutopa mu makoma woonda. Kuponyera mchenga kumawalola kukulitsa makulidwe a khoma ndi 3.2 mm kwinaku akusunga kuyanjanitsa kwa GD&T pazinthu zisanu ndi chimodzi zofunika kwambiri. Gawoli tsopano likugwira ntchito kwa miyezi 18 popanda kutayikira.
Zomwe Zimapangitsa Ntchito Yoponya Mchenga Kukhala Yodalirika
Kudalirika kumayamba kalekale kutsanulira. Zimayamba ndi mapangidwe apangidwe omwe amachititsa kuti zitsulo zikhale zolimba mu cobalt-nickel alloys-mpaka 2.8% kutayika kwa voliyumu ndi 1.8% kwa chitsulo chotuwa. Imapitilira kutsimikizira mphamvu yakusindikiza, kuzungulira kwa nkhungu komwe kumayendetsedwa ndi chinyezi, komanso kutsika kwa kutentha kwenikweni mkati mwa ± 5 ° C wa chandamale. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., gulu lililonse la mchenga limaphatikizapo:
- Tsatanetsatane wa satifiketi ya Raw material-kuchokera pa nambala ya kutentha kwa ng'anjo mpaka lipoti lomaliza
- In-process radiographic inspection (RT Level II) ya porosity yamkati m'madera ovuta
- Kutsimikizika kwazithunzi pogwiritsa ntchito Zeiss CMM ndi ISO 10360-2 kutsata
- Kulimba kwa mapu kudutsa magawo osiyanasiyana kutsimikizira mawonekedwe a microstructure
Palibe macheke a "zitsanzo-zokha". Palibe kuchotserapo magulu. Kujambula kulikonse kumadutsa ndondomeko yonse-ngakhale ma prototypes.
Kumene Kuponyera Mchenga Kumakumana Ndi Machining Molondola-Ndipo Chifukwa Chake Kuli Kofunika
Ntchito yoponya mchenga yomwe imayima pagawo la shakeout imapereka theka la yankho. Mtengo weniweni umawonekera pomwe kutulutsa kumagwirizana ndi kuthekera kwa CNC. Kuphatikizika kwathu koyima kumatanthauza gulu lomwelo lomwe limatsimikizira zojambula zanu zojambuliranso zimakonza mphero ya 5-axis ya geometry yomaliza ya doko pa maziko a mpope. Timayika makina mwachindunji monga-cast datums-palibe chowonjezera chachiwiri-kuchepetsa zolakwika zochulukirapo mpaka 0.08 mm pachinthu chilichonse. Kwa mapulagi a AMS 5387 cobalt alloy, izi zikutanthauza kuti panalibe kukhazikika kwa Ø0.025 mm kupitirira 120 mm kutalika, osati ± 0.15 mm momwe zimakhalira pambuyo pokonzanso.
Kulumikizana kolimba kumeneku ndikofunikira kwambiri pazinthu zomwe sizili wamba: ma eccentric winch shaft roller okhala ndi mano ophatikizika a zida, ma valve olowera m'njira zambiri okhala ndi njira zodutsana, kapena ma nozzles amtundu wa cobalt okhala ndi mbiri zapakhosi. Sitikakamiza kupanga mapangidwe kukhala maenvulopu amtundu wamba. M'malo mwake, timapanga ma mageti, kuyika kwa chokwera, ndi katsatidwe ka makina panthawi yowunikira uinjiniya - kotero malingaliro opanga amafika zida zisanayambe.
Kusankha Bwenzi Lanu—Kuposa Mtengo Pa Kilogalamu
Funsani woyang'anira zogula aliyense amene akugwira zida za hydraulic kapena mafuta: mtengo wotsika mtengo nthawi zambiri umawononga kwambiri kuchedwa, kutayika, kapena kulephera kwamunda. Ntchito yoponya mchenga yowona imadziwonetsera yokha m'njira zitatu - palibe yomwe imawonekera papepala la mawu.
- Chilango chakuthupi: Kodi amachokera ku mphero zovomerezeka za AMS 5387-kapena amavomereza katundu "ofanana" opanda zolemba zochizira kutentha?
- Njira yowonekera: Kodi atha kugawana zipika zoyeserera za nkhungu, kutsanulira ma chart a kutentha, ndi zolemba zakale zamakanema a RT-osati malipoti omaliza okha?
- Kujambula bwino: Kodi amawona kusamvana kwa GD&T koyambirira? Mwachitsanzo, kutchula kulolerana kwa udindo pa chinthu chopangidwa ndi abwana ochita masewera - popanda kuwerengera ndalama zomwe zimapangidwira?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. zolemba sitepe iliyonse. Kujambula kulikonse kumakhala ndi ID yapadera yolumikizidwa ndi zolemba zake zonse zadijito: kusanthula kwamankhwala, deta yoziziritsa, zopindika za CMM, ndi zithunzi zomaliza. Kutsatiridwa kumeneko sikutsata zisudzo - ndi momwe timalekanitsira vuto limodzi mu dongosolo la magawo 200 ndikuletsa kubwereza.
Kuchita bwino kwa ntchito yoponya mchenga sikuyezedwa ndi matani kapena kutembenuka kokha. Imayesedwa mu nthawi - ya mapampu anu, magalimoto anu, makina anu opanikizika. Imayesedwa ngati palibe zonena za chitsimikiziro, mogwirizana ndi kuuma kowerengera pamagulu khumi, ndi chidaliro kuti gawo la pampu la cobalt 6 lichita chimodzimodzi kaya lalamulidwa lero kapena miyezi khumi ndi iwiri kuchokera pano. Pomwe kufunikira kukukulirakulira, zida zamakampani anthawi yayitali - komanso zovuta za aloyi zikukwera - maziko omwe akatswiri azitsulo ndi metrology adzafotokozera zaka khumi zikubwerazi zopanga zitsulo zodalirika. Ntchito imeneyo siyamba ndi mchenga, koma motsimikiza.
