Pamene mainjiniya amatchula a kuponya zitsulo fakitale kwa ma valve othamanga kwambiri a hydraulic valves kapena nyumba zapampu za cobalt-alloy, sikuti amangogula magawo-akuteteza kukhazikika kwapamwamba pansi pa katundu wa 350-bar, kukhulupirika kwa microstructure pambuyo pa chithandizo cha kutentha, ndi zero kulolerana kwa porosity mu njira zovuta kuyenda. Tawona mapulojekiti ambiri akuchedwa - osati chifukwa cha zolakwika za kapangidwe kake, koma chifukwa cha kuthekera kosagwirizana: zida zoponyera mchenga zotumizidwa kumasitolo a CNC popanda ndalama zopangira makina, zopangira ndalama zokhala ndi zovuta zotsalira zomwe zidasokonekera pomaliza kugaya, kapena magulu a aloyi akulephera kutsimikizika kwa AMS 5387 ngakhale malipoti oyeserera mphero "otsimikizika". Kulondola sichowonjezera. Zimapangidwa pamawonekedwe aliwonse - kusankha kwazinthu, kapangidwe ka nkhungu, kuwongolera kolimba, komanso mpumulo wopsinjika pambuyo poponya.
Chifukwa Chake Kuponyera Mwatsatanetsatane Kumayambira Kale Asanathire
Zolephera zambiri zimabwereranso ku kusiyana kumodzi: kusagwirizana pakati pa zolinga zazitsulo ndi ndondomeko. Mphuno ya nickel ya cobalt sikuti "yongoponyedwa ndiye yopangidwa ndi makina." Kuchita kwake kumadalira kukhazikika kolunjika kuti agwirizane ndi zomangira za dendritic motsutsana ndi njira zakukokoloka. Izi zimafunikira kuziziritsa koyendetsedwa bwino, makulidwe a zipolopolo za ceramic zosinthidwa pagawo lililonse, ndi kutentha kwanthawi yayitali komwe kumakhala mkati mwa ± 5 ° C pagulu lonse lazachuma. Tidayeza kulimba kwa 12% m'magawo a aloyi a T800 pomwe chipolopolo chisanatenthedwe ndi 8 ° C basi - zokwanira kuyambitsa kutayika msanga kwa mavavu amafuta & gasi.
Apa ndipamene kuphatikiza koyima kumasintha zotsatira. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Kuponya sikungoperekedwa kunja. Imalumikizidwa ndi kuchuluka kwa makina, kutsata zinthu, ndi kutsimikizika kwa GD&T. Makasitomala akatumiza chojambula cha nyumba ya silinda yapampu ya piston ya AMS 5387, gulu lathu limawunikira masinthidwe a makulidwe a khoma *asanamangidwe* nkhungu -osati pambuyo poyang'ana nkhani yoyamba. Timayika zigawo zocheperapo kuposa 4.2 mm pomwe chiwopsezo cha kuchepa chimaposa kuthekera kwa 92%. Timasintha khomo kuti tipewe chipwirikiti pa doko la 12-mm-diameter zone. Ndipo timatseka manambala azinthu zopangira kuponya kulikonse, kuwalumikiza mwachindunji ndi nthawi yothira kutentha, zipika za ng'anjo yamoto, ndi data yomaliza ya CMM.
Zothandizira Zinayi Zowona Zapadziko Lonse Zogwira Ntchito Mwachangu (Popanda Kusokoneza Umphumphu)
- Mayankho a Design-for-Casting: Timabwezeretsanso zolemba zopangira mkati mwa maola 48-osati "kuchepetsa zovuta," koma mawu omveka ngati "onjezani fillet radius kuchoka pa R0.8 mpaka R1.2 pamphambano A kuti tipewe kung'ambika kotentha; izi zimawonjezera 0.7g kulemera koma zimachepetsa kuchuluka kwa zidutswa kuchokera 22% mpaka 3%.
- Kutsata Njira Zophatikiza: Pakuti castings zitsulo amafuna <± 0.025 mm kuzungulira pa bore 120-mm, timagwiritsa ntchito njira yopangira ndalama pafupi ndi ukonde + kupukuta mwatsatanetsatane mkati-osati CNC yonse kuchokera ku billet. Mtengo wazinthu umatsika 63%; nthawi yozungulira ikucheperachepera 41%.
- Batch Traceability Yomangidwa-Mu: Chitsulo chilichonse chimakhala ndi code ya QR yokhala ndi laser yolumikizana ndi lipoti lake la melt chemistry, zakale zamakanema a radiographic, ndi mapu olimba. Sipadzakhalanso ma spreadsheet ophatikizana pa nthawi ya kafukufuku wa ISO.
- Kumaliza Kugwirizana ndi Ntchito: Wodzigudubuza wachitsulo wosapanga dzimbiri wa shaft wodzigudubuza safuna kupukutira pagalasi. Imafunika Ra 0.8 µm pamalo onyamula katundu ndi Ra 3.2 µm m'malo osalumikizana nawo - otsimikiziridwa ndi optical profilometry, osati ma chart ofananitsa.
Malonda Osanenedwa Mafakitole Ambiri Amabisala
Otsatsa ena amalonjeza "ISO-certified casting metal factory" pomwe akupanga njira zoyambira. Izo zimapanga madontho akhungu. Nthawi ina tidafufuza wogulitsa wina yemwe akufuna kuti awononge ndalama zonse m'nyumba - koma tidapeza kuti zipolopolo zawo zatha, popanda kuwongolera kukhuthala kwa slurry kapena kuviika nthawi. Zotsatira zake? Kusiyanasiyana kwa makulidwe a zipolopolo mpaka ± 0.4 mm, zomwe zimapangitsa kuti mabowo azing'ambika mu 18% ya maziko a pampu. Kukwera mtengo kwenikweni kumatanthauza kukhala ndi zosintha zomwe zili zofunika: kukhulupirika kwa nkhungu, kuwongolera mbiri yamafuta, ndi mayankho anthawi yeniyeni a NDT-osati kungoyang'ana mabokosi pachikalata chotsimikizira.
Ndicho chifukwa chake malo athu amayendera zipata zamtundu wofananira: kutsimikizira kwa zinthu zomwe zikubwera (OES spectroscopy, osati ma cert a mphero), mu ndondomeko ya CMM imayang'ana pambuyo pa kugwedezeka ndi mankhwala asanayambe kutentha, ndi kuyesa komaliza kogwira ntchito-monga hydrostatic pressure kugwira pa 1.5 × ntchito yogwira ntchito kwa mphindi 30 pa thupi lililonse la valve. Palibe chomwe chimatumiza popanda miyeso yonse, zitsulo, komanso kutsata magwiridwe antchito.
Zomwe Mungafunse Wothandizira Wanu Wotsatira Wopanga Zida Zachitsulo
Osafunsa "Kodi ndinu ovomerezeka ndi ISO?" Funsani m'malo mwake:
- "Ndiwonetseni malipoti atatu omaliza a CMM a gawo lomwe lili ndi zovuta za GD&T ndi zathu, makamaka momwe mudachitira zowona pa Ø12 ± 0.01 mm zokhudzana ndi datum."
- "Kodi mumatsimikizira bwanji zofananira zolimbitsa thupi? Kodi mumagwirizanitsa malo omwe amadziwikiratu ndi zotsatira zenizeni za X-ray-ndikusintha mayendedwe moyenerera?"
- "Pamene gulu la aloyi la T800 likuwonetsa mphamvu zokolola zotsika ndi 5% kuposa momwe zimakhalira, ndondomeko yanu yoyambira ndi chiyani? Kodi ndikuchiritsanso, kapena mumapatula kusinthasintha - kusungunuka, kutentha kwa madzi, kapena kuzizira kwa nkhungu?"
Mafunso awa amavumbula kuya kwa ntchito. Amalekanitsa mafakitale omwe amayendetsa njira ndi omwe amangowatsatira.
Kulondola kuponya zitsulo fakitale sichimatanthauzidwa ndi ng'anjo zake kapena ma CMM - zimatanthauzidwa ndi momwe zimatsekera mwamphamvu pakati pa khalidwe lakuthupi, fizikiki yamoto, ndi zofunikira zogwirira ntchito. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amapanga loop mu dongosolo lililonse: kuchokera pamilomo ya cobalt-alloy yomwe imapulumuka 500 ° C panjinga yotentha mpaka kuyika chitsulo. <± 0.05 mm kutsika pamaziko a pampu a 600-mm. Cholinga sikungopereka. Kuchotsa kufunikira kwa kukonzanso, kukonzanso, kapena kulephera m'munda-kotero dongosolo lanu limagwira ntchito momwe mukufunira, kusuntha pambuyo pakusintha, chaka ndi chaka.
