Mainjiniya akamatchula ntchito zamafakitale zopangira mchenga wachitsulo, sikuti amangoyitanitsa magawo - akuteteza kukhulupirika kwapang'onopang'ono, kukhazikika kwapang'onopang'ono pamatenthedwe, komanso kudalirika kwanthawi yayitali m'malo ovuta komanso opsinjika kwambiri. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera zigawo zopitilira 12,000 zachitsulo za ma hydraulic valve matupi, nyumba zapampu ya piston, ndi zodzigudubuza za winch center shaft-chilichonse chimatsimikiziridwa motsutsana ndi zomwe AMS 5387 zitsulo, ISO 9001 amayendera oyendetsa magalimoto ku North America.
Chomwe chimalekanitsa kutulutsa kogwira ntchito ndi kofunikira kwambiri sikumangokhalira nkhungu-ndi momwe machitidwe akuthupi, kusanjika kwa kulekerera kwa makina, komanso kusanja kutentha kumasinthira panthawi yopanga. Tawona makasitomala akukana magawo pambuyo pa miyezi 18 akugwira ntchito - osati chifukwa cha porosity kapena kuchepera, koma chifukwa tsankho laling'ono m'malo olowera lidawonjezera kuvala kwa ma pistoni ozungulira. Chifukwa chake kuponya chitsulo mchenga kuponya fakitale sichitengera kuumba mchenga ngati njira yodziyimira yokha. Ndilo mfundo yoyamba mumayendedwe ogwirizana kwambiri: kutsata kwa mchenga wobiriwira → kuwongolera kokhazikika kokhazikika → mpumulo wapambuyo pa 650 ° C → CNC-makina kukhazikitsidwa kwa data → Kutsata kwa GD&T kotsimikizika kwa CMM pamabowo ovuta ndi malo osindikizira.
Ogulitsa ambiri amapereka "kuponya mchenga." Ndiochepa omwe amawongolera unyolo wathunthu-kuchokera ku satifiketi yazinthu zosaphika mpaka kuyesa komaliza. Timangopeza ISO 14001-certified gray iron (GG25/GG30) ndi ductile iron (GJS-400-18, GJS-500-7) yokhala ndi malipoti a ladle. Gulu lililonse limayesedwa spectrographic musanathire. Pakuumba, timawunika kuchuluka kwa chinyezi (4.8-5.2%), permeability (120-140), ndi compactibility munthawi yeniyeni-osati ndi macheke, koma pogwiritsa ntchito masensa ophatikizidwa mumizere yathu yosakanikirana. Ndipo chifukwa kukula kwa mchenga kumasiyanasiyana ndi chinyezi komanso kutentha kozungulira, malo athu oyambira amakhala ndi ± 2 ° C ndi 55% RH chaka chonse. Kusasinthasintha kumeneko kumatipangitsa kuti tigwire ± 0.15 mm pa 300 mm OD cylinder housings-popanda kugaya kachiwiri.
Koma kupanga zolondola kokha sikokwanira. Nyumba ya valve yoponderezedwa imatha kukumana ndi mawonekedwe onse - ndikulepherabe pa bar 280 ngati kupsinjika kwamkati kumasokoneza mpando pansi pakutentha kwamafuta. Ndiko komwe kuphatikizika koyima ndikofunikira. Makina athu opangira chitsulo chilichonse amaponya. Palibe ma handoffs. Palibe kukonzanso. Timagwiritsa ntchito ma datum omwewo popanga mapatani ndi CNC kugwira ntchito - kotero kuti nkhope yosindikizira imatchulanso malo omwewo omwe adakhazikika mu nkhungu. Pazigawo zapampu za cobalt-alloy ngati ma nozzles a AMS 5387, timaphatikiza kuyika kwa ndalama kwa geometry yokhala ndi mipanda yopyapyala ndi zoyambira zamchenga-kenako timamaliza zonse pakukhazikitsa kumodzi pa 5-axis DMG MORI NTX 1000. Zotsatira zake? Pamwamba pa roughness Ra ≤ 0.8 µm pankhope zokweretsa, zero rework pa 94% ya zomanga zoyamba.
Sitikulitsa mtengo wamtengo wotsika kwambiri - timakulitsa mtengo wotsika kwambiri wa umwini. Izi zikutanthauza kulangiza za kukweza kosayenera kwa T800 kobalt pomwe GG30 yokhala ndi nitride hardness ikupereka moyo wofanana wautumiki pamaziko a pampu. Zikutanthauza kuyika chizindikiro cha ma angles pansi pa 0.5° pounikanso zojambulazo—pateni isanadulidwe—chifukwa tikudziwa kuti zinthuzo zimayambitsa kukokera, kung’ambika pamwamba, ndi mphamvu yotulutsa mphamvu mosagwirizana. Zimatanthawuza kutumiza malipoti amtundu uliwonse ndi dongosolo lililonse, kuphatikiza nambala ya kutentha, kulimba kwamphamvu, kuuma, ndi zojambula za CMM motsutsana ndi CAD yodziwika. Pamene kasitomala wakumwera chakum'mawa kwa Asia amafunikira mayunitsi 240 a chogudubuza cholowera m'bwalo chokhala ndi 0.02 mm runout tolerance, tidapereka m'masiku 22 - osati mothamanga, koma potseka ma parameters panthawi yopangira ma prototype ndikuzigwiritsanso ntchito pamlingo. Ndicho chenicheni chogwira ntchito ndi a kuponya chitsulo mchenga kuponya fakitale zomangidwa kuti zigwire ntchito, osati kungopanga.
