Ntawm chav kawm, nrog bolts thiab txiv ntseej los txuas rau saum npoo, qhov chaw ntawm lub workpiece yuav tsum tau xuas nrig ntaus, uas ua rau kom muaj kev ntxhov siab nyob rau hauv lub workpiece thiab muaj peev xwm ua kom puas qhov chaw, tshwj xeeb tshaj yog nyob rau hauv lub perforated ib feem, uas yog ib tug tsis zoo. ntsia hlau txuas.Thiab suav hais tias yog txiv ntseej.
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 taw qhia bolts, laum khoom, daim phiaj thiab ntoo bolts, thiab lawv kuj tau tsim nyob rau hauv ntau qib.Ob hom iav tuaj yeem siv 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 qws.Lub ntsia hlau core ntawm lub hexagonal ntsia liaj qhov rooj muaj ib tug tej yam thiab sib npaug ntev raws. cov ntsia hlau, thiab cov kab uas hla sab nraud yog ntsuas los ntawm sab nraud.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.
Muaj bolts thiab ceev tuaj nyob rau hauv ntau qib, feem ntau yog ua los ntawm hlau, hlau thiab stainless hlau qib.Iron bolts thiab txiv ntseej ua nyob rau hauv qib 4.8 thiab 5.6 muaj cov ntsiab lus carbon tsawg, yog mos thiab du, thiab feem ntau yog muag nyob rau hauv daim ntawv ntawm txias galvanized. silver plating.Steel bolts yog qhov siv ntau tshaj plaws ntawm cov khoom siv bolts thiab siv rau cov qib hauv qab no.
Stainless hlau ntsia liaj qhov rooj qib kuj tseem siv nyob rau hauv kev lag luam uas lub zog tensile qis dua cov hlau bolts, uas yog, lub zog tensile nyob rau hauv kev lag luam yog sib npaug rau 700 N / m2, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas raug corrosive gas nyob rau hauv cov av noo. .Nws muaj ob hom kev ua haujlwm ntawm cov hlau bolts, ib qho yog qib 304, hu ua A2, thiab lwm yam yog qib 316, hu ua A4.
