Pamene makina a hydraulic akulephera pansi pa mphamvu ya 350-bar, pamene nyumba zapampu zimasweka pambuyo pa maola 12,000 ogwirira ntchito, kapena pamene mphuno za cobalt-nickel zimaphwa mofulumira kuposa momwe amayembekezera - akatswiri samaimba mlandu mapangidwe. Amazitengeranso ku lingaliro limodzi: kukhulupirika kwakuthupi kophatikizidwa ndi kukhulupirika kowoneka bwino mu fakitale yopangidwa ndi fakitale ya alloy mechanical parts.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. wathera zaka zoposa khumi akuthetsa vuto lenilenilo—osati mwanthanthi, koma m’sitolo. Tawonapo kuponyedwa kwa AMS 5387 kugwedezeka panthawi ya chithandizo cha kutentha chifukwa cha kapangidwe ka tirigu kosagwirizana. Takonzanso ma roller a T800 alloy center shaft katatu chifukwa cha ming'alu yaying'ono yobisika pansi. Izi si zongopeka. Ndi maphunziro a m'munda omwe amawongolera momwe timapangira makina, kupanga, ndi kutsimikizira gawo lililonse.
Chifukwa chiyani ma aloyi opangidwa ndi faifi amafunikira zambiri kuposa luso la CNC
Ma aloyi a Nickel monga Inconel 718, Hastelloy C-276, ndi AMS 5387 sachita dzimbiri ndipo amakhalabe ndi mphamvu zopitirira 650°C—koma amagwiranso ntchito molimba kwambiri, samatenthetsa bwino, komanso amavala zida zodulira mwamphamvu. Sitolo yokhazikika ya CNC sitha kupirira ± 0.01 mm pa nyumba ya silinda yapampu ya piston ya 420-mm-diameter yopangidwa kuchokera ku T800 alloy popanda njira zodzipatulira zapanjira, kuzungulira kwa kutentha, komanso mayendedwe a metrology.
Ichi ndichifukwa chake kuphatikiza koyima ndikofunikira. Pamalo athu a Qingdao, kuponya sikumatuluka. Kuponyera mchenga ndi kuyikapo ndalama kumachitika pansi pa denga limodzi—pafupi ndi malo opangira makina ambiri omwe amawunikidwa tsiku lililonse. Timawongolera kutentha kwa nkhungu, kuchuluka kwa kulimba, ndi mpumulo wa post-cast stress isanadulidwe koyamba. Palibe ma handoffs. Palibe kusiyana kwa batch-to-batch pakusiyana kwa dendritic. Ma microstructure obwerezabwereza-ndipo ndipamene kukhazikika kumayambira.
Timayesa izi tsiku ndi tsiku: kasitomala adapempha mapulagi 18 ofanana a cobalt aloyi kuti azigwiritsa ntchito mafuta othamanga kwambiri. Batch 1 idadutsa kuwunika kwa CMM koma idalephera kuyesa kophulika pa bar 412. Micro-CT inavumbulutsa porosity yobisika pafupi ndi phewa lomata - losawoneka ndi kuyang'ana pamwamba. Tinasintha mapangidwe a gating, kutsitsa kutentha kwa 23 ° C, ndikuwonjezera kugwedezeka kwa ultrasonic panthawi yolimba. Gulu 2 linali ndi mipiringidzo 487. Kuwongolera kumeneku kumangokhalapo pomwe mainjiniya opanga makinawo amakhala pamodzi pakuwunika kwa DFMA.
"Kulondola" kumatanthauza chiyani pazigawo zofunika kwambiri zautumwi
Kulondola sikungolekerera zolimba. Ndilo kugwirizanitsa ntchito pakati pa geometry, metallurgy, ndi malo ogwira ntchito. Thupi la valve yokakamiza liyenera kusindikizidwa - koma liyeneranso kupulumuka panjinga yotentha popanda kusweka pamawonekedwe a weld. Winch center shaft roller iyenera kuzungulira bwino-koma kulimba kwake kuyenera kupitirira HRC 52 *ndipo* kukhalabe ndi mphamvu yapansi pa nthaka kuti zisawonongeke.
Ichi ndichifukwa chake protocol yathu yabwino imayika zotsimikizira pamfundo zinayi zomwe sizingakambirane:
- Kutsimikizira zakuthupi: Koyilo iliyonse kapena ingot imanyamula ma MTR athunthu, kuphatikiza kusanthula kwazithunzi ndi malipoti a kukula kwambewu - osati kutsimikizira giredi
- Kuwunika kwa CMM mkati: Pambuyo pa roughing, theka-malinga, ndi kumaliza-pa makina owerengetsera omwewo, pogwiritsa ntchito ndondomeko yomweyi.
- Kuyesa kogwira ntchito: Ma valve opanikizika omwe amayesedwa pa 1.5 × ovotera kuthamanga; mapampu amazungulira mozungulira komanso amawunikiridwa ndi helium mass spectrometry
- Kutsata kwathunthu: Gawo lililonse limalumikizana ndi nambala yake ya kutentha, mtundu wa pulogalamu ya makina, ID ya opareshoni, ndi sitampu yoyendera
Izi sizowonjezera-injiniya. Ikupewa mtengo wotsikirapo wa $ 280,000 pomwe nyumba ya silinda imodzi yosweka imayimitsa pampu yamatope yamafuta akunyanja kwa maola 72.
Pomwe makonda amasiya kukhala owopsa - ndikuyamba kupereka ROI
Otsatsa ena amatengera magawo omwe si ovomerezeka. Timawatenga ngati mwayi wochotsa mitundu yolephera. Chaka chatha, European OEM idatibweretsera chojambula chamtundu wa AMS 5387 nozzle wokhala ndi njira zoziziritsa za asymmetric. Wogulitsa wawo wam'mbuyomu adatchula masabata a 14 ndikukana udindo wapatuka pakuyenda kupitirira ± 8%. Tinayendetsa kuyerekezera kwamafuta, kukonzanso ma baffles amkati kuti tipititse patsogolo kusinthasintha kwa liwiro, ndikuperekedwa m'masabata a 9-ndikupotoka kotuluka komwe kumayesedwa pa ± 2.3% pamayunitsi onse a 12.
Motani? Potengera GD&T osati ngati zolemba, koma ngati chilankhulo chogwira ntchito. Chojambula chikanena za kulolerana kwa Ø0.05 mm mogwirizana ndi datum axis, timatsimikizira axis *pamaso* kupanga—osati pambuyo pake. Kumapeto kwa pamwamba kumafuna Ra 0.4 µm pankhope yosindikiza, timagwiritsa ntchito kutembenuza kwa diamondi-osati kugaya-chifukwa kugaya kumayambitsa kuwonongeka kwapansi komwe kumayambitsa ming'alu ya kutopa pansi pa cyclic loading.
Chilango chimenecho chimakula. Kaya mukufuna ma valve okakamiza asanu kapena maziko a pampu 300 pa kotala iliyonse, mayendedwe athu owonda amatseka nthawi yozungulira, zokolola zakuthupi, ndi zokolola zoyambirira - osasiya kuwongolera zitsulo.
Kusankha bwenzi—osati wongopereka katundu—pazigawo zamakina opangidwa ndi faifi tambala
Ufulu fakitale yopangidwa ndi fakitale ya alloy mechanical parts sichimangokwaniritsa zofunikira. Imayembekezera komwe mafotokozedwe amachepa. Imadziwa kuti mphamvu yamphamvu ya AMS 5387 imatsika 12% ngati njira yothetsera vutoli iposa 1180 ° C - ngakhale MTR itati "mkati mwamtundu uliwonse." Zimamvetsetsa kuti T800 ya mchenga imafunikira magawo osiyanasiyana owombera kuposa momwe amapangira ndalama - chifukwa kugawa kotsalira kumasiyana.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pamzerewu wa sayansi yazinthu ndi kupanga molondola. Sitikusungiramo zinthu zonse zomwe sizinalembedwe. Timakonza zotsatizana mozungulira ntchito ya gawo lanu, osati kuchuluka kwa makina athu. Malo athu ogwirizana ndi ISO ku Qingdao amapereka zida zotsimikizika za cobalt-nickel ku North America, Europe, ndi Southeast Asia —osati ngati zinthu zamakatale, koma ngati mayankho ovomerezeka.
Ngati polojekiti yanu yotsatira ikukhudzana ndi kupanikizika kwambiri, kutentha kwambiri, kapena kuvala kwapamwamba-ndipo mukufunikira zigawo zomwe zimagwira ntchito monga momwe zimapangidwira, kusuntha pambuyo pa kusintha, chaka ndi chaka-yambani ndi kufufuza zinthu, kukhwima kwapang'onopang'ono, ndi kutsimikizira dziko lenileni. Osati timabuku. Osati malonjezo. Kukonzekera kotsimikiziridwa.
