Kev ua kom zoo ntxiv ntawm cov qauv khoom tam sim no yog qhov tseem ceeb ntawm kev hloov pauv rau cov tuam txhab fastener nyob rau theem no.Kev hloov maj mam hloov ntawm cov pa roj carbon tsawg hexagon ceev rau hauv feem ntau ua cov khoom nruab nrab carbon steel A194 2H-chav txiv ntoo yuav ua rau lub tuam txhab tau txais txiaj ntsig ntau qhov chaw.Vim li no, qhov zoo ntawm cov txiv ntoo muaj qhov xav tau ntau dua ntawm cov txheej txheem tsim khoom thiab kev npaj.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua raws li cov hauv qab no: cov phiaj xwm tswj kev ua tau zoo thiab kev tshuaj xyuas tshwj xeeb.
Ua ntej, kev npaj ua ntej ntau lawm.
Thib ob, random tshuaj xyuas ntawm kev tsim khoom.
Thirdly, qhov kawg tshuaj ntsuam afer xa.
Ua ntej tshaj plaws, kev npaj ua ntej tsim muaj xws li: cov neeg ua haujlwm cuam tshuam, cov khoom siv raws li txoj cai, cov khoom siv pwm, cov txheej txheem tsim khoom, cov khoom siv raw, thiab lwm yam.
Txawm li cas los xij, nws muaj peb yam tseem ceeb: a, kev npaj pwm;b, xeem txoj kev;c, kev tswj cov txheej txheem ntau lawm uas ua rau muaj kev xav tau ntau dua rau cov khoom no.
Ua ntej, tsom mus rau kev npaj pwm: los ntawm kev txiav txim rau pwm npaj mus rau ntau lawm, peb yuav tsum txhim kho cov khoom pwm.Peb txiav txim siab tias cov khoom tsim khoom yuav tsis ncua los ntawm kev tsim cov pwm kom txog thaum npaj txhij.Qhov no yuav tsum muaj cov khoom muag txaus los xyuas kom meej lub sijhawm voj voog no uas feem ntau yog nyob ib ncig ntawm 20-25 hnub.
Qhov thib ob, txoj kev tshuaj xyuas;nyob rau hauv qhov txuas no, peb yuav tsum tau them sai sai rau qhov kev sim ntawm cov cuab yeej thiab cov txheej txheem.Peb paub tias cov cuab yeej sim yooj yim suav nrog vernier calipers, micrometers, xov gauges, Rockwell hardness machines, tensile test machines, thiab lwm yam, feem ntau cov lag luam ib txwm xaiv qhov kev tshuaj ntsuam ntawm sab thiab random sampling soj ntsuam.
Thaum kawg, nws yog kev tswj ntawm cov txheej txheem tso zis: zoo li, txoj kev specifications, threading thiab mechanical zog.Txhawm rau kom ntseeg tau tias kev siv cov txiv ntseej, peb yuav tsum tswj hwm thawj peb yam khoom, thiab cov tsos tuaj yeem ua tiav los ntawm kev tshuaj xyuas qhov muag.Yuav kom tswj tau qhov tseeb ntawm cov xov sab hauv, nws yog ib qho tsim nyog yuav tsum tau ua rau hauv txoj kab uas hla lubrication plug gauge.Txhua pawg ntawm cov neeg soj ntsuam thiab cov neeg ua haujlwm tuaj yeem tshawb xyuas cov txheej txheem ntawm cov txiv ntoo;Nws kuj tso siab rau kev tsim precision ntawm cov pwm molding thiab kev hloov kho ntawm qhov kev txiav txim siab hauv kev tsim khoom kom ntseeg tau tias.Qhov yuav tsum muaj rau cov khoom siv kho tshuab yog nyob ntawm raw khoom tiav thiab kev kho cua sov, thiab peb feem ntau tsis quav ntsej qhov tseem ceeb tshaj plaws - kev cog qoob loo xwm ntawm cov neeg ua haujlwm.
