Ike Hexagon Isi Bolt Electric Fastener

A na-akpọ bolts hexagon dị elu, nke a na-eji ígwè dị elu ma ọ bụ mkpa itinye nnukwu ibu ibu, nwere ike ịkpọ bolts dị elu. A na-ejikarị bolts ike dị elu eme ihe maka njikọ nke àkwà mmiri, okporo ígwè, nrụgide dị elu na ultra-elu-nrụgide akụrụngwa. Njiji dị n'ụdị bolt a na-agbaji agbaji. Ọ dị mkpa ka agbanye bọtịnụ ike dị elu etinyere na akụrụngwa nrụgide dị elu iji hụ na akara nke akpa ahụ. Taa, nrụpụta dị elu nke na-anọchi anya nnukwu ụgbọ elu, nnukwu akụrụngwa na-emepụta ike, ụgbọ ala, ụgbọ oloko na-agba ọsọ, nnukwu ụgbọ mmiri na nnukwu ngwá ọrụ zuru oke ga-abanye na ntụziaka mmepe dị mkpa. Ya mere, fasteners ga-abanye na ọkwa dị mkpa nke mmepe. A na-eji bolts ike dị elu maka njikọ nke igwe dị mkpa. Mgbasa ugboro ugboro ma ọ bụ ụzọ dị iche iche nrụnye nrụnye nwere ihe dị elu chọrọ maka bolts ike dị elu. Ya mere, ogo nke ọnọdụ elu ya na eri ziri ezi ga-emetụta ndụ ọrụ na nchekwa nke onye ọbịa. Iji meziwanye ọnụọgụ esemokwu ma zere corrosion, ọdịdọ ma ọ bụ mkpọchi mgbe a na-eji ya eme ihe, ihe ndị a chọrọ na teknụzụ na-egosi na a ga-eji nickel phosphorus plating gwọọ elu ya. Ihe mkpuchi mkpuchi ga-adị n'etiti 0.02 ~ 0.03mm, na mkpuchi ahụ ga-abụ otu, oke na enweghị pinholes.

Ihe mkpuchi: 18Cr2Ni4W, 25Cr2MoV ígwè; Nkọwa ọkọlọtọ: M27 ~ M48. N'ihi na ụdị ígwè a dị mfe ịmepụta ihe nkiri na-agafe agafe n'elu, na ihe nkiri a na-agafe agafe ga-eme ka ihe mkpuchi ahụ ghara inweta chemical nickel phosphorus oyi akwa na mma adhesion, a ga-emerịrị ihe mgbochi pụrụ iche iji wepụ ihe nkiri ahụ na mbụ, na usoro. kwesịrị iwere iji gbochie ịmaliteghachi ya, ka o wee hụ na adhesion dị mma n'etiti mkpuchi mkpuchi na mkpụrụ. N'otu oge ahụ, nnukwu geometric size nke bolt na-eme ka ihe isi ike nke nickel phosphorus plating ọgwụgwọ na ịchọpụta àgwà dị na usoro ahụ. Usoro eruba nke nickel phosphorus plating maka nnukwu ike bolts nwere akụkụ atọ:

Akụkụ nke mbụ bụ usoro nhazi nke mbụ, gụnyere nkenke na nlele anya tupu ịwụnye, nkwụsị akwụkwọ ntuziaka, nsị nsị, pickling, electroactivation na flash nickel plating nke elu-ike bolts;

Part II electroless nickel plating usoro;

Akụkụ nke atọ bụ usoro ọgwụgwọ mgbe emechara, gụnyere hydrogen mbanye okpomọkụ ọgwụgwọ, polishing na okokụre ngwaahịa nyocha. Dị ka ndị a:

Nyocha ihe mejupụtara kemịkalụ nke bolts → izi ezi na nleba anya ọdịdị nke bolts tupu etinyere → ntuziaka dereasing → nlele anya → immersion degenreasing → ịsacha mmiri ọkụ → ịsacha mmiri oyi → pickling acid → ịsacha mmiri oyi → activation electro Ịsacha mmiri oyi → ịsacha mmiri deionized → chemical nickel plating → ịsacha mmiri oyi → mmiri oyi na-asa → hydrogen mbanye → polishing → nyocha ngwaahịa emechara.
