Tau kawg, nrog bolts thiab txiv ntseej los txuas rau saum npoo, qhov saum npoo ntawm lub workpiece yuav tsum tau xuas nrig ntaus, uas ua rau kom muaj kev ntxhov siab nyob rau hauv qhov chaw ua haujlwm thiab muaj peev xwm ua kom puas qhov chaw, tshwj xeeb tshaj yog nyob rau hauv qhov perforated, uas yog qhov tsis zoo ntawm cov ntsia hlau txuas.
Bolts thiab txiv ntseej yog tsim raws li ntau yam qauv, txhua yam muaj feem xyuam rau ib qho kev lag luam tshwj xeeb.Industrial bolts thiab txiv ntseej muaj cov qauv sib txawv kiag li los ntawm cov ntsiab lus ntawm cov ntsia hlau, cov cuab yeej laum, daim phiaj thiab ntoo bolts, thiab lawv kuj tau tsim nyob rau hauv ntau qib.Ob hom iav siv tau rau kev lag luam bolts thiab ceev. Coarse threaded ntxhib iav siv cov hniav zoo tshaj plaws hauv kev sib txuas thiab cov iav zoo: lawv tsuas yog siv rau qib siab steel bolts thiab txiv ntseej thiab tuaj yeem smoothed rau hauv qab ntawm qib thiab cov tav no yuav ploj.
Yav dhau los, muaj bolts yog tsim nyob rau hauv daim ntawv ntawm hexagonal bolts los yog nyob rau hauv daim ntawv ntawm cov poj niam bolts, uas yog tiag tiag ib tug tag nrho-threaded los yog tag nrho-iav pas nrig.Cov ntsia hlau core ntawm lub hexagonal bolt muaj ib tug tej yam thiab sib npaug ntev raws li cov ntsia hlau, thiab cov txheej txoj kab uas hla yog ntsuas los ntawm cov txheej tav. Nws muaj ib tug niaj hnub tsim ntau tshaj li hexagon screws. Nws tau maj mam pom qhov chaw dav hauv kev lag luam thiab niaj hnub no ntawm ntau lub tshuab ua haujlwm, tshwj xeeb tshaj yog vim nws txoj kev sib txuas yooj yim.Nyob hauv qab no peb tshuaj xyuas cov qauv siv dav siv ntau tshaj plaws thiab cov txiv ntoo.
Cov bolts thiab txiv ntseej tuaj nyob rau hauv ntau qib, feem ntau yog ua los ntawm hlau, hlau thiab stainless hlau qib.Iron bolts thiab ceev ua nyob rau hauv qib 4.8 thiab 5.6 muaj cov ntsiab lus tsis tshua muaj carbon, yog mos thiab ductile, thiab feem ntau yog muag nyob rau hauv daim ntawv ntawm txias galvanized nyiaj plating.Steel bolts yog cov feem ntau lug siv cov nram qab no hom ntawm industrial bolts.
Cov qib stainless hlau ntsia liaj qhov rooj kuj tseem siv rau hauv kev lag luam uas lub zog tensile qis dua li cov hlau bolts, uas yog, lub zog tensile hauv kev lag luam yog sib npaug li 700 N / m2, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas raug corrosive gas nyob rau hauv cov av noo.Muaj ob qib kev ua haujlwm ntawm steel bolts, ib qho yog grade 304, thiab qib A. 316, npe A4.
