Ua noʻonoʻo paha ʻoe i nā mea i hoʻohana ʻia no ka pahu excavator?Ma kēiaʻatikala, e kūkākūkā mākou i nā mea i hoʻohana pinepineʻia i nā pine, nāʻaoʻao, nāʻokiʻoki, nā hale a me nā niho o nā bākeke excavator.

Nā Pin ʻEli

Hana ʻia nā pine excavator me ke kila AISI 4130 a i ʻole 4140.AISI 4000 moʻo kila he chrome molybdenum kila.Hoʻomaikaʻi ʻo Chromium i ka pale ʻana a me ka paʻakikī, ʻoiai ʻo ka molybdenum e hoʻomaikaʻi i ka ikaika a me ka paʻakikī.

ʻO ka helu mua, 4, e hōʻike ana i ka pae o ke kila a me kāna hui ʻana i ka hui nui (ma kēia hihia, chromium a me molybdenum).ʻO ka helu ʻelua 1 ka pākēneka o nā mea hoʻohuihui, ʻo ia hoʻi ma kahi o 1% chromium a me molybdenum (ma ka nuipa).ʻO nā huahelu ʻelua hope loa he mau kalapona kalapona i 0.01% hoʻonui, no laila he 0.30% kalapona ka AISI 4130 a he 0.40% ka AISI 4140.

Ua mālama ʻia paha ke kila i hoʻohana ʻia me ka paʻakikī induction.Hoʻopuka kēia kaʻina hana wela i kahi ʻili paʻakikī me ke kūpaʻa ʻaʻahu (58 a 63 Rockwell C) a me ka loko malleable e hoʻomaikaʻi ai i ka paʻakikī.E hoʻomaopopo i ka hana maʻamau o nā bushings me nā mea like me nā pine.Hiki ke hana ʻia kekahi mau pine haʻahaʻa mai ka AISI 1045. He kila kalapona maʻamau kēia e hiki ke paʻakikī.

Nā ʻaoʻao Bākeke Excavator a me nā ʻaoʻao ʻoki

Hana ʻia nā ʻaoʻao o ka bākeke a me ka lau me ka pā AR.ʻO nā papa kaulana loa ʻo AR360 a me AR400.ʻO AR 360 kahi kila haʻahaʻa kalapona haʻahaʻa haʻahaʻa i mālama ʻia i ka wela e hāʻawi i ke kūpaʻa ʻaʻahu maikaʻi loa a me ka ikaika hopena kiʻekiʻe.Hoʻomaʻamaʻa ʻia ka AR 400, akā hāʻawi ia i ke kūpaʻa ʻaʻahu a me ka ikaika hua maikaʻi.Hoʻopaʻa pono ʻia nā kila ʻelua a hoʻopaʻa ʻia e hoʻokō i ka maikaʻi o ka huahana koʻikoʻi o ka bākeke.E ʻoluʻolu, ʻo ka helu ma hope o AR ʻo ia ka paʻakikī Brinell o ke kila.

ʻO ka pahu ʻeke ʻeli

Hana ʻia nā hale Bākeke mai ka ASTM A572 Grade 50 (i kākau ʻia i kekahi manawa A-572-50), ʻo ia ʻo He kila kila haʻahaʻa ikaika kiʻekiʻe.Hoʻopiliʻia ke kila me ka niobium a me ka vanadium.Kōkua ʻo Vanadium i ka ikaika o ke kila.He mea kūpono kēia ʻano kila no nā pūpū bakeke no ka mea, hāʻawi ʻo ia i ka ikaika maikaʻi ʻoiai ʻoi aku ke kaumaha ma mua o nā kila like e like me A36.He mea maʻalahi hoʻi ke wili a me ke ʻano.

Nā niho Bākeke Excavator

No ke kūkākūkā ʻana i ke ʻano o nā niho bakeke, pono e hoʻomaopopo ʻia ʻelua mau ala o ka hana ʻana i nā niho bakeke: ka hoʻolei ʻana a me ke kala ʻana.Hiki ke hana ʻia nā niho pahu pahu me ke kila kila haʻahaʻa me ka nickel a me ka molybdenum e like me nā mea hoʻohui nui.Hoʻomaikaʻi ʻo Molybdenum i ka paʻakikī a me ka ikaika o ke kila a hiki ke kōkua i ka hoʻohaʻahaʻa ʻana i kekahi ʻano o ka corrosion pitting.Hoʻomaikaʻi ʻo Nickel i ka ikaika, paʻakikī a kōkua i ka pale ʻana i ka corrosion.Hiki ke hana ʻia me ka isothermal quenched ductile hao i mālama ʻia i ka wela e hoʻomaikaʻi ai i ka pale ʻana a me ka ikaika hopena.Hana ʻia nā niho bākeke i hoʻopaʻa ʻia me ke kila kila wela, akā ʻokoʻa ke ʻano o ke kila mai ka mea hana i ka mea hana.Hoʻomaikaʻi ka mālama wela i ka hana ʻaʻahu a hoʻonui i ka ikaika hopena.

Ka hopena

Hana ʻia nā bākeke excavator i nā mea like ʻole, akā ʻo kēia mau mea āpau o ke kila a i ʻole ka hao.Koho ʻia ke ʻano o nā mea e like me ke ʻano o ka hoʻouka ʻana a me ka hana ʻana o ka ʻāpana.
