Akatswiri akamatchula zitsulo za mavavu opangira madzi, mapampu, kapena ma shaft a mawichi—zigawo zomwe siziyenera kupitirira mipiringidzo ya mipiringidzo 300 kapena kutuluka kwa mafuta odzaza mchenga—samangofunika wogulitsa. Amafunikira mnzawo yemwe wawona ming'alu yomweyi ikufalikira mumphuno ya AMS 5387 cobalt alloy pa 450 ° C. Ndani anayeza kusuntha kwapang'onopang'ono pamatenthedwe asanu azinthu zochokera ku T800. Ndani akudziwa komwe porosity ya mchenga imabisala - komanso momwe makina a CNC amatha kuwulula asanaunike komaliza.
Ichi ndichifukwa chake ma OEM padziko lonse lapansi ku North America ndi Europe nthawi zonse amabwerera ku a kuponyedwa zitsulo fakitale mizu osati mu voliyumu, koma yotsimikizira: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Likulu lawo ku Qingdao, si malo opangira ntchito. Ndi malo opangira olondola omwe amamangidwa mozungulira zinthu zitatu zosakambitsirana - kubwereza kwamkati mkati mwa ± 0.015 mm pamabowo ovuta, kusasunthika kwazitsulo pamagulu onse, komanso kutsatiridwa kwathunthu kuchokera pa satifiketi ya billet yaiwisi mpaka lipoti lomaliza la CMM.
Mphamvu zawo zimayamba ndi chilango chakuthupi. Ma aloyi a cobalt-nickel ngati AMS 5387 samapangidwa - amakopeka. Kukula kwamafuta kusagwirizana pakati pa chida ndi chogwirira ntchito, kulimbikira ntchito kupitilira 300%, ndi tsankho la carbide zonse zimafuna kusintha kwanthawi yeniyeni. QINGDAO QIANGSENYUAN siipereka chithandizo cha kutentha kwakunja kapena kudalira mapepala amtundu wamba. M'malo mwake, amapanga matenthedwe ozungulira ndi ogulitsa zinthu zotsimikizika, amatsimikizira chilichonse chomwe chikubwera motsutsana ndi kukula kwambewu ya ASTM E112 ndi miyezo ya ASTM E381 macrostructure, ndikusunga kutsata kwathunthu kwa batch-kuphatikiza nambala yosungunuka, tsiku lothira, ndi zipika za ng'anjo. Makasitomala akamafunsa "T800-equivalent," yankho silolemba-ndizofanizira zolembedwa za hardness mbiri, intergranular corrosion resistance pa ASTM G28, ndi moyo wophulika pa 650°C.
Kukhazikika uku kumapitilira mpaka kuphatikizika kwa ndondomeko. Otsatsa ambiri amasiyanitsa kuponyera ndi makina. QINGDAO QIANGSENYUAN amawaphatikiza mwadala. Nyumba zachitsulo zoponyedwa ndi mchenga zimakhala zochepetsera nkhawa * isanakwane* mphero ya CNC-osati pambuyo pake-chifukwa zovuta zotsalira zimasokoneza geometry ya bore potembenuka komaliza. Mabotolo a cobalt opangidwa ndi Investment amakhala pafupi ndi mawonekedwe a ukonde ndi 0.3 mm stock allowance, kenako amasunthira molunjika ku 5-axis Machining yokhala ndi zoziziritsa kukhosi komanso kufufuza mkati. Palibe ma handoffs. Palibe kusuntha kwakukulu pakati pa ntchito. Palibe mipukutu yokonzanso. Malo awo ogwirizana ndi ISO amathandizira kutsika kwapang'onopang'ono, kusokonekera kwa makina, ndi kukula kwa kutentha monga zosinthika - osati masitepe okha. Umu ndi momwe amakhalira ndi ma callouts a GD&T ngati kulekerera kophatikizana Ø0.05 mm ku MMC kudutsa zida 12 panyumba imodzi yapampu ya piston.
Kudalirika kwenikweni kumawonekera popereka - osati zongoyerekeza. Makasitomala amafotokoza nthawi zotsogola zokhazikika pamadongosolo apakatikati (ma PC 50-500) chifukwa kukonzekera kupanga kumagwiritsa ntchito mapu oyenda bwino, osati kuyerekezera kwa kalendala. Pamene wopanga mpope waku Europe amafunikira mipando 87 ya ma valve a AMS 5387 yokhala ndi ma geometri 17 apadera, gululo lidayendetsa uinjiniya nthawi imodzi: kutsimikizira kutanthauzira kwa GD&T m'maola 48, ndikuyika gawo lokhala ndi mipanda yopyapyala lomwe limakonda kupotozedwa panthawi yotsekera, ndikupereka mawonekedwe osinthidwa omwe amadula kukanidwa ndi 62%. Palibe kuchedwa kwa "kupanga kuzimitsa". Palibe madongosolo osintha omaliza. Zigawo zogwira ntchito, panthawi yake, zokhala ndi zolemba zonse zowunikira-kuphatikiza masikanidwe owoneka bwino omwe amakutidwa pa CAD mwadzina kuti apange mapu opotoka.
Kuyang'ana m'tsogolo, kuyang'anako kumanola—osati kukulitsa. Akuyika ndalama za R&D m'njira zosakanizidwa zopangira makina opangira ma aloyi apamwamba pomwe njira zachikhalidwe zimafikira malire: lingalirani zamanja zosapanga dzimbiri zokhala ndi mayendedwe ozizirira amkati, zomalizidwa mu kukhazikitsidwa kumodzi pogwiritsa ntchito malo otembenuza mphero. Kukula kwa ziphaso kumayang'ana zofunikira za gawo - ASME B16.34 ya mabungwe a valve, API 6A ya zida zamutu, EN 15085 pa ntchito za njanji - osati ISO 9001 yokha. Koma pachimake sichinasinthe: a kuponyedwa zitsulo fakitale zomwe zimayesa kupambana osati mu matani otsanuliridwa, koma paziro zolephera pamisonkhano yovuta kwambiri. Chifukwa mumakina a hydraulic ndi mapampu amafuta, kudalirika sikuli kanthu. Ndizomwe zimafunikira.
