Hexagon socket bolts ntawm dub high-rise steel qauv

Vim li cas ntau qhov chaw nyiam siv hexagon socket screws, nws zoo li cas?
Lub npe hu ua hexagon socket taub hau ntsia liaj qhov rooj hais txog lub taub hau cylindrical nrog cov duab ntawm lub qhov (socket), uas tuaj yeem hu ua hexagon socket taub hau ntsia hlau, lub taub hau hexagon taub hau ntsia hlau thiab lub qhov (socket) hexagon ntsia hlau.

Vim li cas hexagon, tsis yog plaub lossis tsib?
Ntau tus neeg muaj lus nug dua, vim li cas thiaj li yuav tsum tsim kom muaj hexagonal tsis yog plaub, tsib lossis lwm cov duab?Lub hexagonal ntsia hlau tuaj yeem tig 60 ° los kho cov duab.Yog hais tias qhov chaw me me, cov ntsia hlau tuaj yeem ntsia tau ntev li ntev tau raws li tus ciaj ntswj tuaj yeem tig 60 degrees, uas yog cov khoom ntawm kev sib haum xeeb ntawm lub kaum sab xis ntawm kev sib hloov thiab qhov ntev ntawm sab.

Yog hais tias nws yog ib lub square, sab ntev ntev txaus, tab sis nws yuav tsum tau twisted 90 degrees los kho cov duab, uas tsis haum rau me me qhov chaw installation;Yog hais tias nws yog ib tug octagon los yog ib tug decagon, lub kaum sab xis ntawm lub graphic restoration yog me me, tab sis sab ntev ntawm lub zog kuj yog me me.Yog, yooj yim rau puag ncig.

Yog hais tias nws yog ib tug ntsia hlau nrog khib-ntaus sab, ob sab ntawm lub ciaj ntswj tsis yog tib yam.Nyob rau hauv thaum ntxov hnub, tsuas muaj rab rawg-zoo li tus wrenches, thiab lub taub hau nrog khib-ntaus sab yog ib tug trumpet-puab qhib, uas zoo li tsis haum rau thov quab yuam.

hexagon socket hardness thiab cov khoom
Feem ntau, feem ntau siv hexagon socket taub hau bolts yog 4.8 qib, 8.8 qib, 10.9 qib, 12.9 qib thiab lwm yam.Feem ntau, cov qib sib txawv ntawm hexagon socket lub taub hau bolts raug xaiv raws li kev xav tau sib txawv, yog li kev ua haujlwm ntawm cov bolts tuaj yeem ua tau zoo dua.Hnub no, Jinshang.com yuav tham nrog koj txog qib hardness ntawm hexagon socket bolts.

Qib hardness

Hexagon socket taub hau bolts raug cais raws li qhov nyuaj ntawm cov ntsia hlau xaim, lub zog tensile, lub zog tawm los, thiab lwm yam, uas yog, qib ntawm hex qhov (socket head bolts), thiab qib twg ntawm hex qhov (socket head bolts) yog qib twg.Cov khoom sib txawv yuav tsum muaj cov qib sib txawv ntawm hexagon socket taub hau bolts sib haum rau lawv.

Hexagon socket lub taub hau bolts tau muab faib ua qhov zoo tib yam thiab siab zog raws li lub zog ntawm qib.Ordinary hexagon socket head bolts xa mus rau qib 4.8, thiab lub zog siab lub taub hau bolts xa mus rau qib 8.8 thiab siab dua, suav nrog qib 10.9 thiab 12.9.Qib 12.9 hexagon socket lub taub hau hau hau screws feem ntau xa mus rau knurled, ntuj dub hexagon socket taub hau hau screws nrog roj.

Qib kev ua tau zoo ntawm hexagon socket taub hau bolts rau steel qauv kev sib txuas yog muab faib ua ntau tshaj 10 qib xws li 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, thiab lwm yam, ntawm cov qib 8.8 thiab siab dua. Kev sib sau ua ke hu ua high-strength bolts, thiab cov bolts yog ua los ntawm cov pa roj carbon tsawg hlau los yog nruab nrab carbon steel thiab kev kho cua sov, tus so feem ntau hu ua cov bolts zoo tib yam.Daim ntawv qhia qib bolt muaj ob feem ntawm tus lej, uas sawv cev rau tus nqi nominal tensile lub zog thiab cov txiaj ntsig piv ntawm cov khoom siv ntsia liaj qhov rooj.

Chav kawm ua haujlwm

Daim ntawv qhia qib bolt muaj ob feem ntawm tus lej, uas sawv cev rau tus nqi nominal tensile lub zog thiab cov txiaj ntsig piv ntawm cov khoom siv ntsia liaj qhov rooj.

Bolts ntawm kev ua tau zoo chav kawm 4.6 txhais tau tias:

1. Lub nominal tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 400MPa;

2. Qhov sib piv ntawm lub zog ntawm cov khoom siv ntsia liaj qhov rooj yog 0.6;lub nominal yield zog ntawm cov khoom siv ntsia liaj qhov rooj yog 400 × 0.6 = 240MPa.

Kev ua tau zoo qib 10.9 siab zog bolts, tom qab kev kho cua sov, tuaj yeem ncav cuag:

1. Lub nominal tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj ncav cuag 1000MPa;

2. Qhov sib piv ntawm lub zog ntawm cov khoom siv ntsia liaj qhov rooj yog 0.9;lub nominal yield zog ntawm cov khoom siv ntsia liaj qhov rooj yog 1000 × 0.9 = 900MPa.

Lub ntsiab lus ntawm qib kev ua tau zoo ntawm hexagon socket taub hau bolts yog tus qauv thoob ntiaj teb.Bolts ntawm tib qib kev ua tau zoo, tsis hais qhov sib txawv ntawm cov khoom siv thiab cov hauv paus chiv keeb, muaj qhov ua tau zoo ib yam, thiab tsuas yog qib kev ua tau zoo tuaj yeem xaiv tau hauv kev tsim.

Cov qib sib txawv muaj tus nqi sib txawv ntawm lub khw.Feem ntau, tus nqi ntawm lub qhov (socket) lub taub hau lub taub hau taub hau bolts yog tus nqi siab dua li ntawm lub qhov (socket head cap bolts).Hauv kev ua lag luam, feem ntau siv yog 4.8, 8.8, 10.9, thiab 12.9.Zonolezer tam sim no muaj qhov (socket head cap screws) hauv qib 4.8, 6.8, 8.8, 10.9, 12.9, thiab 14.9.

Qhov zoo ntawm kev siv hexagon socket bolts

1. tuaj yeem tiv taus qhov hnyav dua.

Nws muaj rau lub zog-kev coj tus kheej qhov chaw, uas yog resistant rau screwing dua flat-blade screws thiab cross-shaped screws nrog tsuas yog ob qhov chaw.

2. tuaj yeem muab faus rau hauv kev siv.

Uas yog hais tias, tag nrho cov txiv ntseej yog sunk rau hauv lub workpiece, uas yuav ua kom lub nto ntawm lub workpiece smooth thiab zoo nkauj.

3. Yooj yim rau nruab.

Piv nrog rau sab nrauv hexagon ntsia hlau, sab hauv hexagon yog tsim rau ntau lub sijhawm sib dhos, tshwj xeeb tshaj yog nyob rau hauv lub sijhawm nqaim, yog li nws yooj yim heev rau kev sib sau thiab tswj, thiab nws kuj yooj yim rau kev debug.

4. Tsis yooj yim rau disassemble.

Cov cuab yeej peb feem ntau siv yog adjustable wrenches, screwdrivers thiab tuag wrenches, thiab lwm yam, thiab tshwj xeeb wrenches yuav tsum tau siv los tshem tawm hexagon socket bolts.Yog li ntawd, nws tsis yog yooj yim rau cov neeg zoo tib yam los disassemble.Tau kawg, yog tias koj muaj kev sib tw, koj tuaj yeem tsim txhua yam ntawm cov qauv txawv txawv.Lo lus nug yog seb tus s
