High Strength Hexagon Head Bolt Electric Fastener

Lub zog siab hexagon bolts, uas yog ua los ntawm cov hlau muaj zog los yog yuav tsum tau siv cov khoom loj, tuaj yeem hu ua lub zog muaj zog bolts. Lub zog muaj zog bolts feem ntau yog siv rau kev sib txuas ntawm cov txuas hniav, rails, high-pressure thiab ultra-high-pressure khoom. Qhov tawg ntawm cov ntsia liaj qhov rooj zoo li no yog nkig tawg. Lub zog muaj zog bolts siv rau cov khoom siv ultra-siab siab yuav tsum tau prestressed los xyuas kom meej lub sealing ntawm lub thawv. Niaj hnub no, kev tsim khoom siab heev uas sawv cev los ntawm cov dav hlau loj, cov khoom siv hluav taws xob loj, tsheb, tsheb ciav hlau ceev, cov nkoj loj thiab cov cuab yeej ua tiav loj yuav nkag mus rau qhov tseem ceeb ntawm txoj kev loj hlob. Yog li ntawd, fasteners yuav nkag mus rau theem tseem ceeb ntawm txoj kev loj hlob. Lub zog muaj zog bolts yog siv rau kev sib txuas ntawm cov tshuab tseem ceeb. Rov qab disassembly lossis ntau txoj kev teeb tsa torque muaj qhov yuav tsum tau ua rau siab zog bolts. Yog li ntawd, qhov zoo ntawm nws qhov chaw saum npoo thiab qhov tseeb xov yuav cuam tshuam ncaj qha rau kev pabcuam lub neej thiab kev nyab xeeb ntawm tus tswv tsev. Txhawm rau txhim kho cov kev sib txhuam coefficient thiab tsis txhob xeb, qaug dab peg lossis jamming thaum siv, cov txheej txheem kev cai hais tias qhov chaw yuav tsum tau kho nrog npib tsib xee phosphorus plating. Lub thickness ntawm txheej yuav tsum nyob rau hauv thaj tsam ntawm 0.02 ~ 0.03mm, thiab cov txheej yuav tsum zoo ib yam, ntom thiab tsis muaj pinholes.

Bolt khoom: 18Cr2Ni4W, 25Cr2MoV steel; Bolt specification: M27 ~ M48. Vim tias cov hlau zoo li no yooj yim los tsim cov zaj duab xis passive rau ntawm qhov chaw, thiab cov zaj duab xis passive no yuav ua rau lub bolt tsis tuaj yeem tau txais cov tshuaj nickel phosphorus txheej nrog adhesion zoo, tshwj xeeb pretreatment ntsuas yuav tsum tau muab tshem tawm cov zaj duab xis ua ntej, thiab ntsuas. yuav tsum tau coj los tiv thaiv nws cov kev tsim dua tshiab, thiaj li ua kom zoo adhesion ntawm plated txheej thiab substrate. Nyob rau tib lub sijhawm, qhov loj geometric loj ntawm lub ntsia liaj qhov rooj nce qhov nyuaj ntawm nickel phosphorus plating kev kho mob thiab nrhiav kom tau zoo hauv cov txheej txheem. Cov txheej txheem ntws ntawm nickel phosphorus plating rau siab zog bolts muaj peb ntu:

Thawj feem yog cov txheej txheem pretreatment, suav nrog precision thiab zoo li tshuaj xyuas ua ntej plating, phau ntawv degreasing, soaking degreasing, pickling, electroactivation thiab flash npib tsib xee plating ntawm high-strength bolts;

Tshooj II electroless nickel plating txheej txheem;

Qhov thib peb yog cov txheej txheem tom qab kev kho mob, suav nrog hydrogen tsav kev kho cua sov, polishing thiab kev tshuaj xyuas cov khoom tiav. Raws li hauv qab no:

Tshuaj muaj pes tsawg leeg tshuaj xyuas ntawm bolts → raug thiab zoo li kev soj ntsuam ntawm bolts ua ntej plating → phau ntawv degreasing → tsos tshuaj ntsuam → immersion degreasing → dej kub ntxuav → dej txias → acid pickling → dej txias → electro activation → dej txias → flash nickel plating Kev ntxuav dej txias → deionized dej ntxuav → tshuaj npib tsib xee plating → deionized dej ntxuav → dej txias ntxuav → hydrogen tsav → polishing → tiav cov khoom soj ntsuam.
