ʻO ka hoʻomaʻamaʻa wela Fastener, ma kahi o ka nānā ʻana i ka maikaʻi maʻamau a me ka mālama ʻana, aia kekahi mau nānā a me ka hoʻomalu maikaʻi kūikawā, i kēia manawa ke ʻōlelo nei mākou i ka mālama wela o kekahi mau wahi mana.
01 Decarburization a me ka carburization
I mea e hoʻoholo pono ai i ka mana kalapona umu, hiki iā ʻoe ke hoʻohana i ka ʻike maka a me ka hoʻāʻo paʻakikī o Rockwell no ka decarburization a me ka carburization no ka hoʻoholo mua.
ʻO ka hoʻāʻo ʻana.
ʻO nā ʻāpana kinai ʻia, i loko o ka mea wili mai ka ʻili a i loko e wili mālie ana i ka ili hoʻokolokolo a me ka puʻuwai o ka nui kalapona i kūlike. Akā, pono kēia i ka mea hoʻohana e loaʻa i nā ʻenehana akamai a me nā ʻulaʻula e ʻike ai i ka hiki.
ʻO ka hoʻāʻo paʻakikī ʻo Rockwell.
Lawe ʻia ma ka ʻaoʻao o ka bolt hexagonal. ʻO ka mua o nā ʻāpana paʻakikī o ka mokulele hexagonal me ka pepa ʻeleʻele i kālai ʻia, ana i ka paʻakikī Rockwell mua. A laila e wili i kēia ʻili i ka sander ma kahi o 0.5mm, a laila e ana i ka paʻakikī o Rockwell.
Inā like ka waiwai o ka paʻakikī o nā manawa ʻelua, ʻaʻole ia he decarburization, ʻaʻole hoʻi ka carburization.
Ke emi ka paʻakikī mua ma mua o ka paʻakikī hope, ʻo ia hoʻi, ua decarburized ka ʻili.
ʻOi aku ka ʻoi aku o ka paʻakikī mua ma mua o ka paʻakikī hope, ʻo ia ka carburization o ka ʻili.
Ma keʻano laulā, ʻo ka ʻokoʻa paʻakikī ʻelua o 5HRC a i ʻole ka liʻiliʻi, me ke ʻano metallographic a i ʻole ke ʻano microhardness, ʻo nā ʻāpana o ka decarburization a i ʻole carburization i loko o ke ʻano o ka hōʻoia.
02 Ka paakiki a me ka ikaika
I loko o ka threaded fastener ho'āʻo, 'aʻole hiki ke hoʻokumu wale 'ia ma luna o ka paakiki waiwai o ka pono manual, hoohuliia i ka ikaika waiwai. Aia kekahi mea paʻakikī i waena.
Ma keʻano laulā, he maikaʻi ka paʻakikī o ka mea, hiki ke hoʻokaʻawale likeʻia ka paʻakikī o ke keʻa o ka'āpana wili, inā lōʻihi ka paʻakikī, ka ikaika a me ka hōʻoiaʻiʻo e hiki ke hoʻokō i nā koi;
Ke ʻilihune ka paʻakikī o ka mea, ʻoiai e like me ka ʻāpana i kuhikuhi ʻia o ka māka, ua kūpono ka paʻakikī, akā ʻo ka ikaika a me ka hōʻoia ʻana i ke koʻikoʻi pinepine ʻaʻole i hoʻokō i nā koi. ʻOi aku ka paʻakikī o ka ʻili i ka palena haʻahaʻa, i mea e hoʻomalu ai i ka ikaika a hōʻoia i ke koʻikoʻi i ka pae kūpono, e hoʻomaikaʻi pinepine i ka waiwai palena haʻahaʻa o ka paʻakikī.
03 Ho'āʻo hou
ʻAʻole lawa ka hoʻāʻo hou ʻana i ka paʻakikī, me ka haʻahaʻa haʻahaʻa haʻahaʻa e hiki ʻole ai i ke ʻano paʻakikī i ʻōlelo ʻia o ka hana hewa ʻole, e hōʻoia i ka piha ʻana o nā waiwai mechanical o nā ʻāpana.
ʻOi aku ka haʻahaʻa haʻahaʻa carbon martensitic steel manufacturing threaded fasteners, haʻahaʻa wela tempering, ʻoiai nā mea mechanical e hiki ke hoʻokō i nā koi, akā ʻo ke ana o ke koʻikoʻi i hōʻoia ʻia, ʻo ke koena elongation fluctuation he nui loa, ʻoi aku ka nui ma mua o 12.5um, a ma kekahi mau kūlana o ka hoʻohana. e lilo i mea hakihaki hikiwawe, ma kekahi mau kaʻa a me ke kūkulu ʻana i nā kī, ua ʻike ʻia ma ke ʻano o ka haki ʻana.
I ka haʻahaʻa haʻahaʻa haʻahaʻa wela tempering, hiki ke hoemi i ka mea i luna, akā, me ka haʻahaʻa kalapona martensitic kila manufacturing 10.9 papa bolts, pono e makaala.
04 Ka nānā ʻana i ka hoʻoheheʻe ʻana o ka hydrogen
Hoʻonui ka maʻalahi i ka hoʻoheheʻe hydrogen me ka ikaika o ka mea hoʻopili. ʻO nā mea hoʻopaʻa milo waho o ka papa 10.9 a ʻoi aʻe, pono e hoʻoheheʻe ʻia nā wiliwili hoʻopaʻa paʻa ponoʻī, nā wili hui pū me nā mea hao hao paʻakikī, a me nā mea ʻē aʻe.
ʻO ka mālama ʻana i ka dehydrogenation ka mea maʻamau i ka umu a i ʻole ka tempering umu, e paʻa ana ma 190 ~ 230℃ʻoi aku ma mua o 4h, no laila e hoʻopuehu ka hydrogen.
"Pono ka hao i kona paakiki pono'i!" No ke ʻano o ka loli ʻana o ka mākeke, ʻo ka hoʻomaʻemaʻe ʻana i ke kaʻina hana hana kekahi o nā ala kūpono e pale aku ai i nā pilikia.
I ke kaʻina hana hoʻomaʻamaʻa wela, he mea nui loa ia e hana i kahi hana maikaʻi ma nā wahi mana kī, ʻo ia kekahi o nā mea e pono ai kēlā me kēia ʻoihana hoʻomaʻamaʻa wela.
