Mainjiniya akamatchula zitsulo zotayidwa za ma hydraulic manifolds, mapampu, kapena ma winch system shafts, sikuti amangoyitanitsa zitsulo - akubetcha pamlingo wokhazikika pansi pa 300-bar pressure, kuvala kukana pambuyo pa kuzungulira 10,000, ndi zero batch-to-batch kuwerengera kwa graphite nodule. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni fakitale yopangira chitsulo si za mtengo wotsika kwambiri. Ndizokhudza kuwongolera zitsulo, kuwongolera njira, ndi kupitiliza kwa uinjiniya.
Chifukwa Chake “Chitsulo Choponyera” Sichinthu Chimodzi Chokha
Tawona ma projekiti ambiri akuyimitsidwa chifukwa kugula "chitsulo chotayira" ngati chinthu. Chitsulo chotuwa (ASTM A48 Class 30B) sichikhala ngati chitsulo cha ductile (ASTM A) chikapangidwa pa 12,000 rpm-kapena chikakumana ndi mpweya wowawasa wa condensate. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Kuponyera kwachitsulo kulikonse kumayamba ndi kufufuza kovomerezeka: malipoti a ladle, ma curve osanthula matenthedwe, ndi kutsimikizira kwa microstructure kudzera pa ISO 945-1. Palibe kuchotserapo. Ngati nyumba yanu ya pampu ya pisitoni ikufuna mtundu wa 3 wa ma graphite morphology okhala ndi ≤2% yaulere ya carbides, timatsimikizira-osaganiza.
Kumene Kuponyera Mchenga Kumakumana Ndi Machining Molondola-Popanda Kusokoneza
Ogulitsa ambiri amagulitsa kunja kapena kupanga makina. Izi zimapanga mipata yocheperako: zolakwika zapamtunda zomwe zidasokonekera CNC isanakhazikitsidwe, kusuntha kwakukulu kosakonzedwa panthawi yamavuto, kupotoza kwa kutentha sikunyalanyazidwa mpaka kuyesedwa komaliza. Timayendetsa njira zonse ziwiri pansi pa denga limodzi—mizere yoponyera mchenga yotsimikizika ya ISO 9001 yomwe imadya molunjika kumalo opangira makina a 5-axis okhala ndi kafukufuku wa Renishaw. Pa nyumba ya silinda yomwe imafuna ± 0.015 mm kuzungulira kutalika kwa 300 mm, timapanga makina obowola * pambuyo * kupsinjika-kuchepetsa kuponya - osati kale. Chifukwa chiyani? Chifukwa tayeza kuchuluka kwa kupsinjika kotsalira komwe kumasokoneza zigawo zokhala ndi mipanda yopyapyala mu ASTM A. Ndipo tikudziwa kuti kudumpha sitepe iyi kumawononga ndalama zambiri kuposa nthawi ya ng'anjo.
Kuphatikiza koyima uku kumapereka maubwino atatu konkire:
- Zolosera zam'mbali: Timakhala ndi ma callout a GD&T ngati kulolerana kwa Ø0.05 mm m'malo olowera ma valve - otsimikiziridwa ndi ma Zeiss CMM osinthidwa kukhala miyezo ya NIST
- Microstructure chilungamo: Zoumba zathu zamchenga zimagwiritsa ntchito silika womangidwa ndi utomoni wokhala ndi mphamvu zowongolera, kuwonetsetsa kuti kuziziritsa kofananako kumalepheretsa kuchepa kwa porosity m'malo ovuta kunyamula katundu.
- Kukonzekera pamwamba: Malo a As-cast amakumana ndi Ra 12.5 µm; Kumaliza kopangidwa ndi makina kugunda Ra 0.8 µm popanda kugaya kwachiwiri-kofunikira kuti zisindikizo zigwirizane ndi mavavu othamanga kwambiri
Pamene Gawo Lanu Lilibe Pagulu Lililonse
“Zopanda muyezo” nthawi zambiri zimatanthawuza “zofunikira kwambiri”. Chaka chatha, European OEM inkafunika pulagi ya cobalt-alloy ya pampu yogwirizana ndi AMS 5387-koma yokhala ndi ulusi wamkati wa 17 ° palibe wapampopi wotuluka pashelu yemwe angadulidwe. Mchitidwe wamba? Zoyika zowotcherera, ndiye kuthamangitsa ulusi. Yankho lathu: zida zamtundu wamtundu wokhazikika wa carbide zomwe zikuyenda pa 85 m / min, zokhala ndi nthawi yeniyeni yogwedera. Zotsatira zake? 100% kutsata mawonekedwe a ulusi, palibe ma microcracks pamizu yozungulira, ndi kutumiza m'masiku 11 - osati masabata a 6. Izi ndi zomwe zimachitika pamene sayansi yakuthupi, njira zopangira zida, ndi chidziwitso cha kagwiritsidwe ntchito zimagwirizana.
Timagwiritsa ntchito ma aloyi opangidwa ndi T800, ma superalloys a cobalt-nickel, ndi chitsulo chapamwamba cha silicon imvi pomwe makina wamba amalephera. Koma chofunika kwambiri ndi ichi: timayimitsa zoopsa zomwe zingapangidwe * tisanatchule. Ngati chojambula chanu chikuwonetsa makulidwe a khoma la 0.3 mm mu bulaketi yachitsulo ya nodular yomwe ili ndi 5G yowopsa - tikuwonetsani makulidwe a gawo locheperako potengera kapangidwe kathu kolimba. Osati kukankhira mmbuyo. Kupewa kulephera.
Zimene “Zodalirika” Zimatanthauza M’kuchita
Kudalirika sikungofuna kutsatsa. Ndi umboni wolembedwa. Chigawo chilichonse chachitsulo chomwe timatumiza chimanyamula kutsata kwathunthu: nambala ya kutentha, kapangidwe ka mankhwala pa ASTM E353, zotsatira zoyeserera, ndi zolemba zowunikira akupanga magawo ovuta. Palibe malipoti a "batch average". Palibe zitsimikizo zapakamwa. Pamene kampani yamafuta aku North America idafuna kutsata API RP 14C panyumba ya winchi ya subsea, tidapereka malipoti a gulu lachitatu - osati mindandanda yamkati yokha.
Chilango chimenecho chimafikira ku mayendedwe. Sitilonjeza "nthawi zotsogola kwa milungu iwiri" kenako ndikusungitsa katundu wandege. Kuyenda kwathu kosasunthika kumaphatikizapo kukonzekera kokwanira, kukonzekera kokwanira kodziwa bwino za botolo, ndi mapangano azinthu ziwiri. Kwa maoda apakati (ma 50-500 pcs), chiwongola dzanja chathu pa nthawi yobweretsera chimayima pa 98.7% m'miyezi 24 yapitayi-zotsimikiziridwa ndi zipika zotumizira makasitomala, osati ma dashboards amkati.
Kusankha Fakitale Yoyenera ya Iron Iron Kumayamba Ndi Mafunso
Funsani wogulitsa wanu: Kodi mungagawire lipoti laposachedwa la ASTM A? Kodi mumachita macheke a CMM pamabowo opangidwa ndi makina - kapena kungoyang'ana komaliza? Kodi kupatuka kwanu kwakukulu kovomerezeka kwa pearlite muzitsulo zotuwira ndi zotani, ndipo mumatsimikizira bwanji? Ngati mayankho ali osamveka bwino, ochedwa, kapena miyezo yodziwika bwino popanda kugwiritsa ntchito - simukulankhula ndi fakitale yopangira chitsulo. Mukulankhula ndi wogawa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amapanga magawo pomwe kulephera sikungachitike. Osati chifukwa timatero-koma chifukwa valavu iliyonse yopondereza, maziko a mpope, zombo zonse za winch shaft shaft roller zokhala ndi umboni wophatikizidwa mu kapangidwe kake, miyeso yake, ndi zolemba zake. Nthawi ina mukafuna zida zachitsulo zopangira ntchito zamafakitale, yang'anani kupyola kalozera. Yang'anani ndondomeko kuseri kwa gawolo.
