Hexagon Head Bolt Electric Fastener

ʻO nā bolts hexagon ikaika kiʻekiʻe, i hana ʻia me ke kila ikaika kiʻekiʻe a i ʻole pono e hoʻopili i ka preload nui, hiki ke kapa ʻia nā bolts kiʻekiʻe. Hoʻohana nui ʻia nā bolts ikaika kiʻekiʻe no ka hoʻopili ʻana i nā alahaka, nā kaʻaahi, nā mea paʻi kiʻekiʻe a me nā mea hana kiʻekiʻe kiʻekiʻe. ʻO ka haʻihaʻi o kēia ʻano pōkā, ʻo ia ka haʻihaʻi. Pono e hoʻopololei ʻia nā bolts ikaika kiʻekiʻe i hoʻohana ʻia i nā mea hana ultra-kiʻekiʻe e hōʻoia i ka sila ʻana o ka ipu. I kēia lā, ʻo ka hana holomua i hōʻike ʻia e nā mokulele nui, nā lako hana mana nui, nā kaʻa, nā kaʻa kaʻa kiʻekiʻe, nā moku nui a me nā pūʻulu nui o nā lako e komo i kahi kuhikuhi hoʻomohala koʻikoʻi. No laila, e komo nā mea paʻa i kahi kūlana koʻikoʻi o ka hoʻomohala ʻana. Hoʻohana ʻia nā bolts ikaika kiʻekiʻe no ka hoʻopili ʻana i nā mīkini koʻikoʻi. ʻO ka wehe hou ʻana a i ʻole nā ​​ʻano hana torque hoʻonohonoho like ʻole nā ​​koi kiʻekiʻe no nā bolts ikaika kiʻekiʻe. No laila, ʻo ka maikaʻi o kona kūlana ili a me ka pololei o ke kaula e pili pono i ke ola lawelawe a me ka palekana o ka mea hoʻokipa. I mea e hoʻomaikaʻi ai i ka friction coefficient a pale aku i ka corrosion, seizure a i ʻole jamming i ka wā o ka hoʻohana ʻana, ʻōlelo ʻia nā koi ʻenehana e mālama ʻia ka ʻili me ka nickel phosphorus plating. ʻO ka mānoanoa o ka uhi i loko o ka laulā o 0.02 ~ 0.03mm, a ʻo ka uhi ʻana e ʻano like ʻole, paʻa a me ka ʻole o nā pinholes.

Mea paʻa: 18Cr2Ni4W, 25Cr2MoV kila; ʻO ka wehewehe ʻana o Bolt: M27 ～ M48. No ka mea he maʻalahi kēia ʻano kila e hana i kahi kiʻiʻoniʻoni passive ma luna o ka ʻili, a ʻo kēia kiʻiʻoniʻoni passive e hiki ʻole i ka bolt ke kiʻi i ka papa nickel phosphorus kemika me ka adhesion maikaʻi, pono e lawe ʻia nā hana pretreatment kūikawā e wehe mua i ke kiʻi, a me nā ana. Pono e lawe ʻia i mea e pale ai i kona hoʻoulu hou ʻana, i mea e hōʻoia ai i ka hoʻopili maikaʻi ʻana ma waena o ka uhi paʻa a me ka substrate. I ka manawa like, hoʻonui ka nui geometric o ka bolt i ka paʻakikī o ka mālama ʻana i ka nickel phosphorus plating a me ka ʻike ʻana i ka maikaʻi i ke kaʻina hana. ʻO ke kaʻina hana o ka nickel phosphorus plating no nā bolts ikaika kiʻekiʻe he ʻekolu mau ʻāpana:

ʻO ka hapa mua ke kaʻina hana pretreatment, me ka pololei a me ka nānā ʻana i nā hiʻohiʻona ma mua o ka plating, manual degreasing, soaking degreasing, pickling, electroactivation a me flash nickel plating o nā bolts kiʻekiʻe;

Māhele II electroless nickel plating kaʻina hana;

ʻO ka hapakolu o ke kaʻina hana ma hope o ka mālama ʻana, me ka mālama ʻana i ka wela o ka hydrogen drive, polishing a me ka nānā ʻana i ka huahana. Penei:

ʻO ka nānā ʻana i ka hoʻohui ʻana i nā bolts → ka pololei a me ka nānā ʻana i nā bolts ma mua o ka hoʻopaʻa ʻana → ka hoʻomaʻemaʻe lima → ka nānā ʻana i ke ʻano → ka holoi ʻana i ka wai wela → ka holoi wai anuanu → pickling acid → ka holoi ʻana i ka wai anuanu → ka hoʻoulu ʻana i ka wai → ka holoi wai anuanu → ka nickel plating → holoi wai anuanu → holoi wai deionized → hoʻopalapala nickel kemika → holoi wai deionized → holoi wai anuanu → hoʻokele hydrogen → polishing → ka nānā ʻana i ka huahana.
