Pamene mainjiniya mu hydraulic system OEMs kapena makampani opangira mafuta akufufuza a China zitsulo kuponyera fakitale, sakuyang'ana mawu otsika kwambiri. Iwo akufunafuna kubwerezabwereza kwa dimensional papampu ya cobalt alloy, kusasinthika kwazitsulo kudutsa 50 AMS 5387 castings, kapena zodabwitsa zero pomwe shaft ya winchi ya T800 ilephera kuyesa kwake kwa hydrostatic. Taziwonapo nthawi zambiri: malo opangira "oyenerera" amapereka mbali zomwe zimayendera zowona-koma zimaphwanyidwa pansi pa 300 bar kuthamanga panjinga chifukwa kapangidwe ka tirigu sikunatsimikizidwe, kapena kuuma kwapansi kumasunthidwa kunja pambuyo pa kutentha.
Kudalirika kotulutsa zenizeni padziko lonse lapansi kumayamba ndi umwini - osati kugulitsa kunja
Ogula ambiri padziko lonse lapansi amaganiza kuti kuponyera ndi kupanga makina ndi ntchito zosiyana. Lingaliro limenelo limapanga ngozi. Pamene kuponyera kumachitika pamalo amodzi, chithandizo cha kutentha m'malo ena, ndi CNC kumaliza chachitatu, zosintha zovuta - monga kugawa kwapang'onopang'ono kotsalira kapena kuyankha kwapang'onopang'ono panjinga yotentha - kumadutsa mipata. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., magawo onse atatu amachitika pansi pa denga limodzi lovomerezeka ndi ISO ku Qingdao. Izi sizothandiza - ndikuwongolera. Timayika maziko a pampu yachitsulo, kenaka timayika ma flange ake okwera ndi nkhope zamadoko munjira yomweyo, pogwiritsa ntchito zida zofananira ndi CMM. Palibe kukonzanso. Palibe kusintha kwa data. Palibe zongoyerekeza za momwe kupotoza kwa kuponya kungakhudzire kutsatira komaliza kwa GD&T.
Tatsimikizira chitsanzo ichi chophatikizika pama projekiti opitilira 127 a ma valve hydraulic valve. Makasitomala m'modzi waku North America adasintha kuchokera pagulu la tier-1 atalephera kutayikira mobwerezabwereza pampando. Kusanthula kwawo kwachiyambi kunawonetsa kusagwirizana kwa ma microhardness gradients mu thupi la valve - chifukwa cha kuzizira kosalamulirika pakati pa kuponyera ndi kutentha kwapambuyo pa makina. Yankho lathu? Ponyani thupi, yambitsani njira yolumikizira * m'nyumba *, kenako malizani pampando pasanathe maola 48 - chinyontho chozungulira chisanayambike kutulutsa okosijeni. Zotsatira: kutayikira kwa zero m'miyezi 18 yogwira ntchito m'magawo 42 akunyanja.
Sikuti ma alloys onse a cobalt amachita chimodzimodzi - komanso mafakitale omwe amawapanga
AMS 5387 cobalt alloy sikuti ndi "zovuta kupanga makina." Kayendedwe kake ka mpweya ka carbide kamasintha kwambiri ngakhale kupatuka kwa 0.3°C panthawi yoyatsa njira. T800 alloy imafuna mitengo yolondola yotentha ya preheat musanakonze zowotcherera - apo ayi, ming'alu ya intergranular imawonekera pomaliza NDT. Otsatsa ambiri amawona zinthu izi ngati "ma superalloys" odziwika bwino. Timawatenga ngati machitidwe amoyo okhala ndi mbiri yakale yotentha.
Protocol yathu yowunikira zinthu imapitilira ma certs a mphero. Chiwopsezo chilichonse chimakhala ndi ID yapadera yolumikizidwa ndi zipika za ng'anjo, kuzimitsa mbiri ya kutentha kwa media, komanso kulimba kwa mapu a pambuyo pakutentha kwa kutentha kudutsa magawo atatu. Pamene wopanga mpope waku Europe amafunikira ma nozzles 22 okhala ndi Rockwell C 42-46 kuuma * ndi * 100% ukhondo wa ultrasonic, tinkayendetsa kutentha kwa woyendetsa, kusinthidwa nthawi yonyowa ndi mphindi 9, ndikuyambiranso kuuma kwa mbiri - tisanapange kupanga. Mlingo woterewu umagwira ntchito kokha pamene zitsulo, kuponyera, ndi QA zimakhala m'chipinda chimodzi.
- Zigawo za Cobalt-nickel: AMS 5387, T800, Stellite 6B -kuponyedwa, kutenthedwa, kumalizidwa mpaka ≤± 0.015 mm kulolerana
- Kuponyedwa kwachitsulo: ASTM A48 Kalasi 30-65, ndi chitsimikizo champhamvu champhamvu pa ASTM E8 pagawo lililonse
- Zitsulo & zitsulo zosapanga dzimbiri: ASTM A216 WCB, A351 CF8M—yojambulidwa mokwanira (ASTM E94) panjira zovuta kwambiri
- Zigawo zamakina za CNC: Kuzungulira kozungulira kolimba kwamitundu yambiri, kuphatikiza ma splines amkati ndi ma bore opindika okhala ndi ≤0.005 mm runout
Kutsimikizika kwakupereka sikulonjezedwa - kumapangidwa
"Malo okhazikika" amatanthauza zinthu zosiyanasiyana kwa anthu osiyanasiyana. Kwa magulu ogula zinthu, sizikutanthauza kuti palibe zolipiritsa zapamphindi zomaliza. Kupanga mainjiniya, kumatanthauza kulandira magawo amutu woyamba * wokhala ndi malipoti oyendera *—osati kungoyang'ana pang'ono, koma zithunzi za microstructure, mamapu olimba, ndi kufufuza malo a mankhwala - musanasaine PPAP.
Timapanga zoperekera munjira - osati mozungulira. Kukonzekera kumagwiritsa ntchito masanjidwe a nthawi ya takt, osati malingaliro a batch-ndi-queue. Ngati nyumba ya silinda ya pampu ya pistoni ikufunika machiritso atatu otenthetsera, makina 5 opangira makina, ndi kumaliza 2 pamwamba, masitepewo amakonzedwa motsatizana ndi nthawi ya buffer yomwe yaperekedwa *kokha* panjira zotsimikizika zolephera - osati kuchedwa kwamalingaliro. Kutumiza kwathu pakanthawi kochepa pamaoda apakati (50-500 pcs) ndi 98.7% m'miyezi 22 yapitayi. Kusiyana kwa 1.3%? Zonse zimatsatiridwa ndi kusintha kwa mainjiniya omwe makasitomala adafunsidwa pambuyo potulutsa nkhungu - osati mipata yamkati.
Kusankha fakitale yaku China yopangira zitsulo sikukhudzana ndi geography-komanso kulumikizana kwaukadaulo
QINGDAO QIANGSENYUAN TECHNOLOGY simatumikira makampani onse. Timayang'ana kwambiri ntchito zomwe kulephera kumakhala ndi zotsatirapo zenizeni: ma hydraulic pressure valves omwe amawongolera kayendedwe ka zofukula, mapulagi a cobalt alloy osindikiza ma manifold a gasi apamwamba a H2S, ma winch center shaft rollers akukweza zida zapansi pa nyanja mu kuya kwamadzi kwa mita 3,000. Kuyang'ana kumeneku kumayendetsa chilichonse, kuyambira pakuwunika kwa ogulitsa zinthu (timayang'ana zolemba za ng'anjo mwezi uliwonse) mpaka kusankha kwathu kwa CMM probe (Renishaw PH20 yokhala ndi scanning ya 5-axis ya ma contour ovuta).
Ngati pulojekiti yanu yotsatira ikufuna kubwerezabwereza kwa ma microstructure opangidwa ndi cobalt, makina ogwirizana ndi GD&T a malo owumitsidwa, kapena kutsatiridwa kwathunthu mpaka pakutentha - ndipo mukufuna kuti iperekedwe popanda kubowola moto kwaukadaulo - ndiye kumanja. China zitsulo kuponyera fakitale si yomwe ili ndi ziphaso zambiri pakhoma. Ndilo lomwe limagwiritsa ntchito zojambula zanu monga momwe zimagwirira ntchito, osati masewera a geometry. Ndi mnzake amene amafunsa *momwe* gawolo limanyamula, *komwe* limadinda, ndi *chiani ngati litalephera*—asanatchule senti imodzi.
