Pamene mainjiniya amatchula a fakitale yopangira zitsulo kwa mavavu ofunikira a hydraulic hydraulic valves kapena nyumba zapampopi zapamwamba, sikuti amangogula magawo - amatulutsa kukhazikika kwa mawonekedwe, kukhulupirika kwa microstructural, komanso kudalirika kogwira ntchito. Kusintha kumodzi kolakwika, gulu limodzi lothandizira kutentha, gulu limodzi losatsimikizika - ndipo dongosolo lonselo limakhala pachiwopsezo cha kutopa msanga, kutayikira, kapena kulephera kowopsa pakulemedwa. Taziwonapo zikuchitika: nozzle ya cobalt-nickel idasweka pa bar 120 pambuyo pa maola 380 ogwirira ntchito chifukwa kapangidwe kake kambewu kamene sikanatsimikizidwe motsutsana ndi zofunikira za AMS 5387. Ichi ndichifukwa chake kulondola sikungonena zamalonda. Ndi ndondomeko yoyendetsedwa-kuyambira ndi kufufuza kwazinthu zopangira ndikutha ndi kuyang'anitsitsa komaliza kwa GD&T.
Chifukwa Chake Kuponyera Pakhakha Sikokwanira-Ndipo Chifukwa Chake Kuphatikizika Sikukambitsirana
Ogula ambiri amaganiza kuti "foundry metal casting fakitale" amatanthauza mchenga kapena kutulutsa ndalama - ndikuyima pamenepo. Koma muzinthu zenizeni zapadziko lapansi monga ma piston pump cylinder housings kapena engineering motor winch center shaft rollers, kuponyera ndi sitepe imodzi yokha. Ma geometry ovuta amakhala m'machining: kulolerana kwapakati kwa ± 0.015 mm pazibowo zamkati, kumalizidwa pansi pa Ra 0.8 µm pankhope zomata, ndi mawonekedwe olimba otenthedwa omwe amayenera kupulumuka kutuluka kwa slurry popanda kung'ambika. Kupeza koyima sikungatsimikizire izi. Ngakhalenso CNC shopu popanda kuwongolera zitsulo pazitsulo zoyambira.
Ndipamene kuphatikiza koyima kumasintha zotsatira. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., kuponyera, kukonza ma axis angapo, ndi kutsirizitsa kumachitika pansi pa denga limodzi logwirizana ndi ISO-mokhala ndi zida zogawana, madongosolo amankhwala otenthetsera, ndi ndondomeko zoyendera za CMM. Pamene pulagi ya T800 yochokera ku cobalt imafuna kuwongolera kokhazikika * ndi * kukhazikika kwa ID/OD, gulu lomwelo limayang'anira kapangidwe ka nkhungu, kuchepetsa kupsinjika kwa post-cast, ndi mphero yamitundu isanu. Palibe ma handoffs. Palibe zolakwika zomasulira za data. Palibe kukonzanso chifukwa chakusokonekera kwa data.
Kupambana Kwambiri Kwazinthu Kupitilira Mapepala Odziwika
"Cobalt alloy" pachojambula sichikukuuzani ngati ndi L-605, Stellite 6B, kapena AMS 5387 - komanso sizitsimikizira kubalalitsidwa kosasintha kwa carbide kudutsa 45-kg kuponyera. Timayesa nthawi zonse kutentha kwa T800 alloy pogwiritsa ntchito mawonekedwe a OES ndikutsimikizira microstructure kudzera pa SEM-EDS pamakuponi okhala ndi magawo. Chifukwa chiyani? Chifukwa kusiyanasiyana kwakung'ono kwa chromium kapena tungsten kumakhudza mwachindunji kukana kukokoloka kwamafuta & mavavu akutsamwitsa gasi. Makasitomala m'modzi adasintha kuchoka ku "CoCr alloy" yamtundu uliwonse kupita ku ma AMS 5387 odziwika - ndikuwonjezera moyo wautumiki kuchoka pa 900 mpaka 2,700 maola ogwirira ntchito mumadzi odzaza mchenga wothamanga kwambiri.
Izi sizongoyerekeza. Zimapangidwa muzopeza zawo zakuthupi: maubwenzi ovomerezeka operekera, malipoti oyesa mphero omwe asungidwa kwa zaka 10+, ndi mayeso ovomerezeka opangidwa asanapangidwe a geometry iliyonse yomwe siili wamba. Ngati chojambula chanu chikufuna nsonga ya aloyi ya cobalt yokhala ndi makulidwe a 0.3-mm pakhoma ndi njira zoziziritsira mkati, amayendetsa woyendetsa, CT-scan zotsatira zake, ndikusintha khomo musanapange kupanga kwathunthu.
Kuwongolera Ubwino Wadziko Lonse—Osati Kungotsatira Mapepala Okha
Chitsimikizo cha ISO 9001 ndichofunika-koma chofunikira kwambiri ndi momwe kuyendera kumachitikira *pakati* pakuwunika. Pamalo awa, chitsulo chilichonse kapena chitsulo chosapanga dzimbiri chimayang'aniridwa ndi magawo atatu ovomerezeka: kutsimikizira kwazinthu zomwe zikubwera (ndi kuyesa kwa PMI), macheke amtundu wa Zeiss CMM amawunikidwa tsiku ndi tsiku, ndikutsimikizira komaliza kogwira ntchito, kuphatikiza kuyezetsa mpaka mipiringidzo 400 yamatupi a valve ndi kutsimikizika kosunthika kwa maziko ozungulira.
Traceability si gawo la database. Ndi zakuthupi: gawo lililonse limakhala ndi nambala yokhazikika ya laser yolumikizidwa ndi kutentha kwake, tsiku loponyera, mtundu wa pulogalamu yamakina, ndi ID yoyendera. Bungwe la European OEM litapempha kuti liwunikire zomwe zidayambitsa pisitoni imodzi yokha, gululo lidatulutsa zolemba zonse - kuphatikiza zipika za kutentha kwa ng'anjo kuchokera pakuwotcha komanso kubwezera zida zolipirira zida kuchokera pachiphaso chomaliza - mkati mwa mphindi 90.
Izi Zikutanthauza Chiyani pa Ntchito Yanu Yotsatira
Ngati mukuyesa a fakitale yopangira zitsulo pazigawo zamafakitale zogwira ntchito kwambiri, funsani mafunso atatu musanapemphe mawu: Kodi angatsimikizire microstructure *ndi* geometry mbali imodzi? Kodi ali ndi tcheni chathunthu - kuchokera pa kusankha kwa aloyi mpaka kumapeto kwa pamwamba - kapena kudalira mavenda a chipani chachitatu panjira zovuta? Ndipo chojambula chikawonetsa kuyitanidwa kwa GD&T ngati kulolerana kwamalo Ø0.05 mm poyerekezera ndi datum A-B-C, kodi amayendera nkhani yoyamba *ndi ma data* anu, osati milingo yadzina chabe?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha kuti inde—kwa onse atatu. Cholinga chawo chimakhala chocheperako: ma valve opanikizika, ma pumps, ma shaft system, ndi zina zomwe zimagwira ntchito pomwe kulephera sikungatheke. Sathamangitsa voliyumu. Iwo amapanga kubwerezabwereza. Ndipo amakulitsa chidaliro - osati ndi timabuku, koma ndi zolemba zowunikira, ziphaso zomwe mungayang'ane, ndi nthawi yobweretsera idakumana pa 94.7% yamaoda apakatikati m'miyezi 27 yapitayi.
Kwa mainjiniya omwe amafunikira zojambula zomwe zimagwira - osati kungofika - mnzake woyenera si fakitale yotsika mtengo yopangira zitsulo. Ndi yomwe imatengera zomwe mwalemba ngati mgwirizano, osati malingaliro.
