Hoʻolauna o Welong Mandrel Bar

ʻenehana hana

ʻO ke kaʻina hana o kahi mandrel bar he mau pae paʻakikī a pololei. ʻO ka mea mua, ʻo ia ka hoʻoheheʻe ʻana o nā mea, e hōʻoiaʻiʻo ana i ka kūlike a me ka maʻemaʻe o ka pahu kumu. A laila, hoʻomaʻamaʻa ʻia, ma o ke kaʻina hana forging, hoʻomaʻemaʻe ʻia ka palaoa o ka mea, a laila e hoʻomaikaʻi ai i kona mau waiwai mechanical a me ke ola lawelawe. Pono ka mandrel forged i ka mālama ʻana i ka wela, kahi kaʻina e hoʻoneʻe i ke koʻikoʻi o loko a hoʻonui i ka paʻakikī a me ke kūpaʻa ʻana o ka mandrel. Ma hope o kēlā, ʻo ka mīkini, me ka huli ʻana, ka milling a me nā hana ʻē aʻe, e hoʻokō ka mandrel i nā koi kūpono o ka hoʻolālā. ʻO ka hana hope loa ka mālama ʻana i ka ʻili, e like me ke kinai ʻana, ka hoʻoulu ʻana, a me nā mea ʻē aʻe, e hoʻomaikaʻi i ke kūpaʻa corrosion a me ka paʻakikī o ka mandrel.

Ka laulā o ka noi a me nā kikoʻī

Hoʻohana nui ʻia ʻo Mandrel bar i nā ʻano ʻano o ka wili wili, e like me MPM (multi-pass rolling mill), PQF (high precision rolling mill) a me FQM (fast rolling mill). ʻO kāna mau kikoʻī like ʻole, mai Φ80 mm a 500 mm ke anawaena, lōʻihi mai 2500 mm a 17,500 mm, hiki ke hoʻokō i nā pono hana like ʻole.

Koho waiwai

ʻO ka mea o ka mandrel bar ka mea maʻamau ʻo AISI H13 a i ʻole ka pae aupuni 4Cr5MoSiV1 a me 36CrNiMoV6. Loaʻa i kēia mau mea waiwai nā waiwai wela kiʻekiʻe a me ka ikaika mechanical e mālama i ka paʻa i ka wela kiʻekiʻe a me nā kaiapuni kiʻekiʻe. ʻAʻole iʻoi aku ka nui o nā mea i hoʻokomoʻia i loko o ka mea mandrel ma mua o 1.0 A, B, C a me D, aʻo ka nui o ka palaoa e hiki i ka 8 aʻoi aʻe paha. ʻO kēia mau mea koʻikoʻi koʻikoʻi e hōʻoia i ka kiʻekiʻe a me ka hilinaʻi o ka mandrel bar.

Waiwai mīkini

ʻO nā mea mechanical i manaʻo ʻia o ka mandrel bar o H13 mea penei: No ka mandrel me ke anawaena ≤200 mm, ʻo ka ikaika tensile ʻo 1127-1274 mpa, ʻo ka ikaika hua he ≥931MPa, ʻo ka elongation ʻo ≥8%, ka pauku shrinkage. ʻo ≥25%, ʻo ≥20J ka hana hopena, a ʻo ka paʻakikī ʻo HB350-390; No ka mandrel me ke anawaena> 200 mm, kona ikaika tensile he 1078-1274 mpa, he ≥882MPa ka ikaika, elongation he ≥8%, he ≥25% ka pauku, he ≥20J ka hopena, he HB330-375 ka paakiki.
