Ke hōʻike ka poʻe ʻenekinia i nā ʻāpana ʻāpana kobalt-nickel no nā paila hydraulic, nā ʻūhā kiʻekiʻe, a i ʻole nā pūnaewele winch waho, e nīnau pinepine ʻia kekahi nīnau: Ma hea ʻoe e kiʻi ai i nā ʻāpana o ka hale hana Co 4 e paʻa ana i ka hoʻomanawanui ma lalo o 0.01 mm—a ola i 20,000+ mau hola i loko o ka lawelawe ʻino a me ka lole kiʻekiʻe? ʻAʻole nā mea hoʻolako āpau e lawelawe i ka AMS 5387 cobalt alloy a i ʻole nā mea hoʻolei i hoʻokumu ʻia ma T800 me ka hoʻopaʻi metallurgical e koi ʻia. Ua ʻike mākou i nā prototypes i hāʻule i ka hōʻoia ʻana no ka nalo ʻana o ka loaʻa ʻana o ka waiwai. Ua ʻike mākou i ka lohi o ka hoʻouna ʻana i ka wā ʻaʻole i uku ʻia ka hoʻolei ʻana i ka wā o ka papahana CNC. ʻO ia ke kumu e hoʻonui ai ka poʻe kūʻai pololei i nā mea kūʻai aku a hele pololei i nā mea hana e hoʻomalu i ka hoʻoheheʻe ʻana i ka alloy a me ka mīkini contour hope loa - e like me QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Hoʻomaka ka mana o ka hale hana Co 4 me ka mana metala — ʻaʻole machining wale nō
He nui nā mea hoʻolako e kapa inoa iā lākou iho "nā loea kobalt alloy" akā ke hoʻolei ʻana i waho i nā waihona ʻaoʻao ʻekolu. Hoʻokumu ia i kahi āpau koʻikoʻi: ʻaʻohe mana ma luna o ke ʻano o ka palaoa, ka māhele carbide, a i ʻole ka hoʻokaʻawale interdendritic. Ma QINGDAO QIANGSENYUAN, hoʻomaka ka holo ʻana o ka hale hana Co 4 me nā pūʻulu waiwai maka i hōʻoia ʻia-AMS 5387 ingots i hōʻoia ʻia e nā hōʻike hoʻāʻo wili a me ka nānā ʻana spectrometric ma mua o ka ninini ʻana. ʻO kā lākou one a me nā laina hoʻolei hoʻolimalima e holo ana ma lalo o nā kiʻi wela koʻikoʻi, a ukali koke ʻia e ka hoʻoheheʻe ʻana i ka hoʻonā a me ka hoʻoluʻu ʻana i ka ASTM A995. No ke aha la keia? No ka mea, ʻaʻole hāʻule nā hale pahu pahu piston mai ka pau ʻana o ka ʻili—akā mai ka hoʻomaka ʻana o microcrack ma nā palena intergranular nāwaliwali i hana ʻia i ka wā paʻa ʻole. ʻO kā lākou hoʻohui kū ʻana, ʻo ia hoʻi ka hoʻolei ʻana i nā ʻāpana, nā pōʻai mālama wela, a me nā ala hana CNC multi-axis i hoʻopaʻa ʻia ma ke ʻano he ʻōnaehana hoʻokahi-ʻaʻole ʻekolu mau ʻanuʻu ʻoki.
ʻO ka hoʻokō honua maoli e pili ana i ka paʻa ʻana o ke ana ma nā pae kaʻina hana
Ua nānā mua mākou i ka pūʻolo GD&T a ka mea kūʻai aku no kahi hui nozzle hoʻoheheʻe cobalt: ʻoiaʻiʻo ka helu ʻana o ± 0.005 mm ma nā lua coaxial ʻeono, ʻeleʻele ʻili Ra ≤ 0.4 µm ma nā maka sila, a me ka paʻakikī 42-46 HRC ma hope o ka ʻelemakule. Ua hala ka ʻāpana i ka CMM inspection post-machining—akā, ʻaʻole i hāʻule ka hoʻāʻo hana ma hope o 72 mau hola o ka ʻike ʻana i ka paʻakai. Ke kumu kumu? ʻAʻole i hoʻokaʻawale ʻia ke koena koʻikoʻi ma waena o ka ʻoki ʻana a me ka hoʻopau ʻana. Hoʻokomo ka hale hana Co 4 ʻo QINGDAO QIANGSENYUAN i ka hoʻoheheʻe ʻana i ke kaumaha ma waena o nā hana mīkini - ʻaʻole wale ma ka hopena. Hoʻohana lākou i ka hōʻoia CMM i loko o ke kaʻina hana ma nā mea kila paʻakikī (ʻaʻole alumini), e hahai i ka hoʻoheheʻe wela i kēlā me kēia hola, a hoʻopili i nā algorithm uku i hoʻopaʻa ʻia i kā lākou mau mīkini Haas a me DMG MORI. ʻO ka hopena: loaʻa mau nā kino valve kaomi i ka 0.008 mm ka holo ʻana ma waena o 300 mm ka lōʻihi—ʻoiai ma hope o ka passivation hope.
ʻAʻole like nā ʻāpana kobalt a pau—e wehewehe ana ka pae waiwai i nā palena noi
- AMS 5387 kobalt huila 6: Hoʻohana ʻia ma kahi e ʻoi aku ai ka ikaika o ka erosion ma mua o ka ikaika tensile—e noʻonoʻo i nā nozzle wahie mīkini jet a i ʻole nā noho valve subsea. ʻO ka wela lawelawe mau loa: 815°C.
- T800 kobalt-ka mea hao hao: Koho ʻia no nā ʻāpana haʻahaʻa haʻahaʻa e like me nā wili pahu waena winch. Hoʻomaikaʻi ka maʻiʻo nickel kiʻekiʻe i ke ola luhi ma lalo o ka torsion cyclic-akā makemake i nā hānai mīkini lohi a me ka paʻa paʻa.
- Nā geometries maʻamau ʻole: ʻAʻole hoʻopili wale kā lākou poʻe ʻenekinia i nā kiʻi. Hāʻawi lākou i nā ʻāpana pā lahilahi i hiki ke hoʻoneʻe ʻia i ka wā e kinai ana, e hōʻike ana i nā kihi kikoʻī no ka wehe ʻana i ka pūpū waiwai, a hōʻoia i ka mānoanoa o ka pā i ka ʻikepili simulation solidification.
ʻAʻole kēia he ʻike theoretical. Kūkulu ʻia ia mai 127 mau hale paʻi paʻa i kūkulu ʻia no nā OEM o ʻEulopa-a me 43 nā loiloi hemahema o nā ʻāpana kobalt i hoʻihoʻi ʻia. I ka noi ʻana o ka mea kūʻai aku i kahi plug maʻamau me nā kahawai hoʻoluʻu kūloko, ʻaʻole lākou i ʻōlelo maʻamau. Ua holo lākou i ka FEA wela, ua hoʻololi i kahi pōʻai HIP i hoʻololi ʻia e hoʻopau i ka porosity i nā paia o ke kahawai, a hāʻawi i nā laʻana ʻatikala mua i nā lā 18-ʻaʻole ʻewalu pule.
Hāʻawi ka loaʻa pololei i ka wānana-ʻaʻole wale ke kumukūʻai
Manaʻo pinepine nā hui kūʻai i ka "factory direct" ʻo ia hoʻi ke kumu kūʻai haʻahaʻa. Akā ʻo ka pōmaikaʻi maoli hoʻomalu. Me QINGDAO QIANGSENYUAN, hana ʻia ka loiloi ʻenekinia me ka metallurgist like i kau inoa ma ka wela AMS 5387 hope loa. Loaʻa i nā palapala hōʻoia waiwai piha ka mōʻaukala wela—ʻaʻole wale ke kemika hope. Loaʻa i kēlā me kēia hoʻouna ʻana i ka traceability pae: helu heheʻe, lā hoʻolei, ID umu ahi wela, a me CMM hōʻike serial. ʻAʻohe subcontractors pahu ʻeleʻele. ʻAʻohe uku haʻahaʻa no ka NDT i hoʻolālā ʻole ʻia. No nā mea kūʻai aku ma ʻAmelika ʻĀkau, ʻo ka manawa alakaʻi no nā kauoha medium-volume (50-500 pcs) he 6-8 mau pule—me ka nānā ʻana i ka piha piha, ka paʻakikī, a me ka nānā ultrasonic. Ka huli ʻana o ka prototype? E like me ka wikiwiki o 11 mau lā hana—me nā palapala FAI piha i hoʻopili ʻia me AS9102.
Ke nānā aku nei i mua, he haiki a hohonu ka nānā ʻana o ka hale hana Co 4: ka haku ʻana i nā kaʻina hana hybrid kahi e hui ai ka hoʻolele kālā ʻana me 5-axis milling, hoʻonui i ka uhi palapala hōʻoia EN 10204 3.2, a me ka hōʻoia ʻana i nā ʻano like ʻole cobalt hou no ka lawelawe hydrogen. Inā koi kāu papahana aʻe i nā ʻāpana i kūpono ʻole i ka spec-akā e hoʻomau i ka hana ma kahi e hoʻohaʻahaʻa ai nā mea ʻē aʻe-e hoʻomaka me kahi kamaʻilio ʻenehana, ʻaʻole kahi noi ʻōlelo. ʻAʻole i hana ʻia ka pololei o ka cobalt. Hana ʻia, hōʻoia ʻia, a hana hou ʻia.
