Ke hōʻike ʻia e nā ʻenekinia 2Cr13 kila kila no nā kino valve hydraulic, nā hale paʻi piston, a i ʻole nā roila winch center shaft rollers, ʻaʻole lākou e koho wale i kahi mea - ke koho nei lākou i ke kūpaʻa dimensional ma lalo o 300+ bar pressure, ke kū ʻana i ke ʻano o ka ʻāʻī ʻana i nā loulou sliding, a me ka paʻakikī mau ma hope o ka mālama ʻana i ka wela. ʻO ia ke kumu e loaʻa ai mai kahi ʻoiaʻiʻo 2Cr13 hale hana kila kila-ʻaʻole kahi mea kūʻai kālepa a i ʻole mea hoʻokumu kumu nui - ʻaʻole hiki ke kūkākūkā. Ua ʻike mākou i ka nui o nā papahana i hoʻopaneʻe ʻia e ka ikaika tensile like ʻole (Rm), HRC 28-32 like ʻole ma hope o ka hoʻoulu ʻana, a i ʻole nā microcracks i hōʻike ʻia i ka wā hoʻāʻo hana.
No ke aha e koi aku ai ʻo 2Cr13 ma mua o ka hoʻoponopono ʻana i ke kila kila
ʻAʻole austenitic ʻo 2Cr13 e like me 304-he martensitic. ʻO ia ke ʻano o kāna hana e pili pono ana i ka mōʻaukala wela pololei: austenitizing ma 980–1050 ° C, ʻaila kinai ʻana, a laila hoʻomaʻamaʻa ma waena o 600-750 ° C e paʻi i ka paʻakikī paʻakikī me ka ʻole o ka kaumaha. Hiki i ka mea hoʻolako maʻamau ke hāʻawi aku i ka "2Cr13" e kū ana i nā kikoʻī kemika GB/T 1220-akā, hāʻule ʻole ma nā mīkini. Ua ana mākou i nā pūʻulu kahi i ʻokoʻa ai ka ikaika o ka hua ± 45 MPa ma waena o nā ʻāpana ma muli o ke kaohi ʻole ʻana o ka hoʻoluʻu ʻana a i ʻole ka lawa ʻole o ka manawa hoʻoheheʻe ʻana. Ka hopena honua maoli? Ua pohā ka hale pahu i ka wā kaʻa paikikala ma 220 bar—ʻaʻole ma ka weld, akā ma ka ʻāpana wela o ka mea kumu.
ʻO kēia kahi e pono ai ka hoʻohui kūʻokoʻa. Ma kā mākou hale Qingdao, mālama mākou i ke kaulahao piha: hōʻoia billet sourcing (me nā hōʻike hōʻike wili e hiki ke ʻike ʻia i ka helu umu), ka mīkini CNC me ka hōʻoia paʻakikī o ka hana, nā umu hoʻoheheʻe ʻia me ka ± 3 ° C uniformity, a me ka nānā hope ʻana CMM e pili ana i nā callouts GD&T-ʻaʻole wale nā ʻāpana nominal. ʻAʻohe lima lima. ʻAʻohe manaʻo kuhi pūʻulu.
ʻEhā mau mana e hoʻokaʻawale ai i kahi hale hana kila kila 2Cr13 maoli mai ke koena
- Ka hoʻopaʻi ʻana i ka metallurgical: Hoʻopaʻa mākou i kēlā me kēia wela 2Cr13 me ka hoʻohana ʻana i ka spark spectrometry pre-machining—a hoʻāʻo hou i ka post-heat-treat e hōʻoia i ka paʻa kalapona a me ka paʻa o ka ratio Cr/Mn. Hoʻokaʻawale nā ʻāpana ʻāpana kobalt AMS 5387 i ke kaʻina hana lab like, no laila, ʻaʻole i manaʻo ʻia ka hoʻohālikelike ʻana o nā mea ʻokoʻa.
- Mīkini-hana wela synergy: ʻO kā mākou mau pūnaewele CNC multi-axis i hui pū ʻia me nā umu hoʻoheheʻe. Hele pololei nā ʻāpana mai ka ʻoki ʻana a hiki i ka huhū - ʻaʻohe hoʻoluʻu ambient e hoʻoulu i ke koena o ke kaumaha. ʻO ka hopena: paʻa nā hale pahū piston ≤0.015 mm i ka ʻae ʻana i ka pōʻai ma Ø180 mm, ʻoiai ma hope o 500-hola i ka ʻike ʻana i ka paʻakai.
- Hoʻoponopono hoʻopau hana: No nā puʻupuʻu kaomi, hoʻohana mākou i ka nitriding i hoʻomalu ʻia—ʻaʻole i ka plating generic—e hoʻoikaika i ka paʻakikī o ka ʻili i ka HV 900+ me ka mālama ʻana i ka paʻakikī kumu. No nā lāʻau winch, hoʻohana mākou i ka wili pololei me ka nānā ʻana i ka ʻili o ka ʻili i ka manawa maoli (Ra ≤0.4 μm) e pale ai i ka hoʻopaʻa ʻana i ka sila mua.
- Hoʻopili ʻia ka traceability, ʻaʻole i hoʻopaʻa ʻia: Hoʻouna ʻia kēlā me kēia ʻāpana 2Cr13 me kahi palapala kikohoʻe e hōʻike ana i ka nui o nā mea maka, ka pihi mālama wela, ka paʻi kiʻi hōʻike CMM, a me ka ID operator. ʻAʻole "hoʻokō" wale nō - hiki ke hoʻolohe.
ʻO ke kumukūʻai o ke koho hewa ʻana—a he aha ke kumukūʻai maoli no ka loaʻa ʻana o ka pono
Ke alualu nei kekahi mau mea kūʻai i ke kumu kūʻai haʻahaʻa. A laila hoʻopau lākou i ʻekolu mau kumukūʻai huna: hana hou (ua ʻike mākou i ka 22% scrap rate ma nā ʻāpana 2Cr13 mai nā hale kūʻai i hōʻoia ʻole ʻia ma muli o ka decarburization), nā hemahema o ka māla (hiki ke kūʻai ʻia kahi hui valve i hopu ʻia i nā lako aila waho he $17k / hola downtime), a me ka hoʻopaneʻe ʻana o ka hoʻolālā (GD&T hōʻoia manaʻo he 72 mau hola ma aneʻi-ʻaʻole 3 mau pule).
Hōʻike kā mākou kumu kūʻai i ke kumukūʻai maoli no ka hana ʻana i ka 2Cr13 pololei: ka uku hoʻopaʻa waiwai i hōʻoia ʻia (non-negotiable), mea paahana i hoʻolaʻa ʻia no ka mīkini paʻakikī kiʻekiʻe (hoʻokomo ʻia ka carbide me ka uhi ʻana o PVD TiAlN), a me ka 100% ka nānā ʻana i nā ʻāpana koʻikoʻi. Akā, haʻi mau ka poʻe kūʻai iā mākou i ka loaʻa ʻana o ROI ma ke kahua prototype—ke hoʻāʻo ko lākou 5 mua i ka hoʻāʻo hana ma ka papa manawa, ʻaʻohe hoʻāʻo lua.
Ke nānā nei i mua: kahi e hele ai ka hana ʻana o Precision 2Cr13
Ke koi aku nei nā noi hou aʻe i ka hoʻohui ʻana ma waena o ka hoʻolei ʻana i ka pono a me ka geometry mīkini. Ke koho nei mākou i nā kaʻina hana hybrid: nā cores-cast 2Cr13 cores me ka hoʻomanawanui ʻana i ka ʻupena (± 0.3 mm), a ukali ʻia e ka contouring ʻelima-axis e hoʻokō ai i ka mānoanoa o ka pā a hiki i 4.2 mm-me ka ʻole o ka hoʻoluhi ʻana i ke ola luhi ma 10⁷ cycles. I ka manawa like, ke hōʻoia nei kā mākou hui R&D i ka ASTM A957-compliant prototyping wikiwiki no 2Cr13, e ʻoki ana i ka manawa alakaʻi mai 12 pule a 18 mau lā no nā geometries kūpono.
Inā makemake kāu palapala noi i ka 2Cr13 stainless steel e hana ana—ʻaʻole e hāʻawi wale i ka pepa—pono ʻoe i kahi hoa hana e mālama i ka metallurgy ma ke ʻano he ʻenekinia, ʻaʻole ke kūʻai. E hoʻomaka ana me ka nīnau ʻana i nā nīnau kūpono: Hiki iā ʻoe ke hōʻike mai iaʻu i ka pihi hoʻonā no ka wela o ka mahina i hala? Loaʻa i kāu hōʻike CMM ka ʻikepili uku hoʻoheheʻe wela? Hoʻopili ʻia paha kāu ʻike ʻike waiwai i nā lāʻau umu—a i ʻole he helu pūʻulu wale nō?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. kūkulu i kēlā mau pane i kēlā me kēia māhele. No ka mea ma nā ʻōnaehana hana kiʻekiʻe, ʻaʻohe mea e like me ke kila kila "maikaʻi".
