Akatswiri akamanena za kuponyedwa kwa nkhungu zokoka pazigawo zazitsulo zolondola kwambiri, sikuti amangosankha njira - akusankha maziko okhazikika, kukhulupirika kwa microstructural, komanso kudalirika kwanthawi yayitali pamikhalidwe yovuta kwambiri. A mphamvu yokoka mold kuponyera fakitale amene amakwaniritsa malonjezo amenewo ayenera kuchita zambiri kuwonjezera pa kutsanulira zitsulo zosungunuka mumchenga kapena mu nkhungu za ndalama. Iyenera kuwongolera kuchuluka kwa alloy solidification, kuyang'anira kutentha kwa ma geometries ovuta, ndikusunga kutsatiridwa kuchokera ku billet yaiwisi kupita ku gawo lomaliza, makamaka pogwira ntchito ndi ma cobalt-nickel superalloys ngati zida za AMS 5387 kapena T800.
Tawona ma projekiti ambiri akuchedwa - osati chifukwa cha zolakwika zamapangidwe, koma popanga zosagwirizana zomwe zimangowonekera makina a CNC atayamba. Kusintha kwa makulidwe a 0.15 mm mu nyumba ya silinda ya pampu ya pistoni kumatha kusokoneza kuyanjanitsa, kuonjezera chiwopsezo chotuluka, ndikuyambitsanso kukonzanso kokwera mtengo. Ndicho chifukwa chake kulondola sikumawonjezedwa pomaliza; imapangidwa munjira yoponya yokha. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kutulutsa kulikonse kwa nkhungu yokoka kumayamba ndi kutsimikizika kwazitsulo-osati ma cert azinthu, koma ma curve okhazikika a batch, malipoti a kukula kwa tirigu, ndi kutsimikizika kwazithunzi motsutsana ndi malire a mankhwala a AMS 5387. Palibe zongoganizira. Palibe njira zazifupi.
Zomwe zimasiyanitsa wokhoza mphamvu yokoka mold kuponyera fakitale kuchokera kwa amene amapambanadi? Kuphatikiza koyima. Othandizira ambiri amatulutsa chithandizo cha kutentha kapena makina omaliza, kupanga mipata yocheperako pomwe kuwonongeka kwamadzi kumasokonekera kapena kupsinjika kotsalira kumasokoneza zofunikira za GD&T. QINGDAO QIANGSENYUAN amathamanga kuponyera, Mipikisano olamulira CNC, ndi pambuyo kuponyera kutentha mankhwala pansi pa denga limodzi ISO-zogwirizana. Pamene mphuno ya aloyi ya cobalt imafuna njira yothetsera 1150 ° C ndikutsatiridwa ndi kuziziritsa kwa mpweya mofulumira-kenako kulolerana molimba mkati - gulu lomwelo limayang'anira mbiri ya kutentha, kulinganiza zida zamakina, ndi kutsimikizira kwa CMM. Chotsatira? Pansi pa 0.02 mm chiwopsezo chonse pamiyendo ya 300 mm, ngakhale pama roller osagwirizana ndi ma winch center omwe amagwiritsidwa ntchito pamagalimoto aukadaulo akunyanja.
Makasitomala nthawi zambiri amafunsa kuti: "Kodi mutha kuponya aloyi ya T800 ya cobalt popanda porosity m'milomo yopyapyala?" Yankho si inde kapena ayi—ndi za kapangidwe ka mageti, kutha kwa nkhungu, komanso kuwongolera kutentha kwanthawi yeniyeni mkati mwa ± 3 ° C. Timagwiritsa ntchito optical pyrometry pa kutsanulira kulikonse, osati ma thermocouples okwiriridwa mu ladles. Ndipo chifukwa cha kutentha kwa T800 kung'amba misozi kumakwera pamwamba pa 1280 ° C, timatenthetsa nkhungu mpaka 220 ° C - osati 180 ° C - kuchepetsa kutentha kwa kutentha. Kusintha kwakung'ono kumeneko kumachepetsa microporosity mu matupi a valve opanikizika ndi 65%, kutengera deta yoyendera ma X-ray kuchokera ku 147 kupanga zambiri kuyambira 2022. Palibe mapepala amtundu uliwonse. Palibe magawo a "mulingo umodzi wokwanira-onse".
Kuchita zinthu n'kofunika kwambiri kuposa makolo. Ngati pampu yanu ikufunika chitsulo choponyera chitsulo chokhala ndi zingwe zomangika, malo osindikizira ndi makina osindikizira, ndi mavalidwe a nitrided - zonse zosungidwa ku ±0.05 mm GD&T callouts - mufunika mnzanu amene amawunikanso zojambula * asanatchule, osati pambuyo pake. Gulu la ainjiniya la QINGDAO QIANGSENYUAN likuwonetsa zoopsa zomwe zingapangidwe pakuwunika koyamba: ma angles ozama kwambiri kuti asamatulutse nkhungu yamchenga, zisindikizo zapakati zomwe zimasokoneza njira zoyenda, kapena ma radii othina kwambiri kuti asadye. Samangonena kuti "ndizotheka." Amawonetsa momwe - ndi kuyika kwachokwera kwapadera, kusankha kozizira, ndi nthawi yogwedeza - ndikuwerengera kuchuluka kwa zokolola ndi nthawi yotsogolera. Kwa North America hydraulic OEMs, izi zikutanthauza kupewa kuchedwa kwa milungu itatu chifukwa chakukanidwa kwa magawo achiwiri.
A zoona mphamvu yokoka mold kuponyera fakitale sichimathamangitsa volume. Imalimbana ndi mtengo wake: magawo omwe amakhala ndi mphamvu yopitilira 20,000+ mumafuta ndi gasi, amakana kuphulika m'mapampu otsetsereka kwambiri, kapena amakhala olimba pambuyo pa maola 500 akupopera mchere. Izi zimafuna zambiri kuposa zida - zimafuna kukumbukira kwamtundu wa aloyi, zolemba zowunikira pagawo lililonse lofunikira, komanso kutsatiridwa kwazinthu zonse mpaka kutentha ndi kuchuluka kwa ogulitsa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga luso limenelo—osati monga chinenero cha malonda, koma monga machitidwe a tsiku ndi tsiku. Sitepe yawo yotsatira? Kutsimikizira ma hybrid casting-machining workflows kwa AMS 5387 impeller blanks-kuchepetsa nthawi yopangira makina ndi 38% kwinaku akuwongolera moyo wotopa kudzera pakukhazikika kowongolera. Kujambula mwatsatanetsatane siukadaulo wakale. Ndiko komwe metallurgy imakumana ndi ntchito yofunika kwambiri.
