Copper Industry Knowledge: Taw qhia txog tooj dag Bolts
Dab tsi yog tooj dag ntsia liaj qhov rooj? Dab tsi yog kev siv lub tshuab tooj dag? Dab tsi yog cov lus qhia rau tooj dag bolts? Lub ntsiab lus ntawm tooj dag bolts: Ib qho khoom siv ua los ntawm tooj dag, lub cylindrical threaded fastener nruab nrog cov txiv ntoo. Bolt: Ib hom fastener uas muaj lub taub hau thiab lub hau ntswj (lub tog raj kheej nrog cov xov sab nraud), uas yuav tsum tau muab sib xyaw nrog cov txiv ntoo kom ceev thiab txuas ob feem nrog los ntawm qhov. Hom kev sib txuas no yog hu ua bolt txuas. Yog hais tias lub txiv ntseej yog unscrewed los ntawm lub bolts, ob qhov chaw yuav tsum tau sib cais, yog li ntawd lub bolt kev twb kev txuas yog ib tug detachable kev twb kev txuas.
Taw qhia rau tooj dag bolts thiab lawv cov kev faib tawm:
Raws li lub zog-kev coj tus kheej hom ntawm kev sib txuas: zoo tib yam thiab nrog reaming qhov. Raws li cov duab ntawm lub taub hau: hexagonal taub hau, puag ncig lub taub hau, lub taub hau square, countersunk taub hau, thiab lwm yam. Ntawm lawv, lub taub hau hexagonal yog feem ntau siv. Feem ntau, lub taub hau countersunk yog siv rau hauv qhov chaw uas yuav tsum tau muaj kev sib txuas.
Taw qhia rau tooj dag bolts thiab cov cuab yeej tsim khoom:
Muaj ntau lub npe rau bolts, thiab txhua tus tuaj yeem hu lawv txawv. Qee tus neeg hu lawv cov ntsia hlau, ib txhia hu lawv bolts, ib txhia hu lawv cov qauv, thiab ib txhia hu lawv fasteners. Txawm hais tias muaj ntau lub npe, lub ntsiab lus yog tib yam, txhua tus yog bolts. Bolts yog ib lo lus dav dav rau fasteners. Lub hauv paus ntsiab lus ntawm bolts yog siv lub cev thiab lej cov ntsiab lus ntawm kev sib hloov ntawm qhov chaw inclined ntawm ib yam khoom thiab kev sib txhuam quab yuam kom maj mam zawm cov cuab yeej ntawm cov khoom thiab qhov chaw.
Bolts yog qhov tseem ceeb hauv lub neej niaj hnub thiab kev tsim khoom thiab kev tsim khoom. Bolts tseem hu ua mov nplej. Nws tuaj yeem pom tias bolts tau siv dav. Daim ntawv thov ntawm bolts suav nrog: cov khoom siv hluav taws xob, cov khoom siv kho tshuab, cov khoom siv digital, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob electromechanical. Cov nkoj, tsheb, kev txuag dej, thiab txawm tias kev sim tshuaj lom neeg kuj tseem siv bolts. Txawm li cas los xij, bolts tau siv ntau qhov chaw. Tshwj xeeb tshaj yog cov precision bolts siv rau cov khoom digital. Cov bolts me me siv hauv DVDs, koob yees duab, tsom iav, moos, electronics, thiab lwm yam.; bolts dav dav rau TV, khoom siv hluav taws xob, khoom siv suab paj nruag, rooj tog zaum, thiab lwm yam .; xws li engineering, kev tsim kho, thiab txuas hniav, cov bolts loj thiab cov txiv ntoo yog siv; cov khoom siv thauj mus los, dav hlau, tsheb ciav hlau, tsheb, thiab lwm yam. siv cov bolts loj thiab me. Bolts muaj cov haujlwm tseem ceeb hauv kev lag luam. Tsuav muaj kev lag luam hauv ntiaj teb, kev ua haujlwm ntawm bolts yuav yog ib qho tseem ceeb.
Taw qhia txog tooj dag bolts: Bolt nrhiav tau: Bolt nrhiav tau muab faib ua ob hom: phau ntawv thiab tshuab. Phau ntawv yog qhov tseem ceeb tshaj plaws thiab feem ntau siv cov kev tshawb pom zoo ib yam. Txhawm rau kom txo qis cov khoom lag luam tsis zoo, cov neeg ua haujlwm tsim khoom lag luam dav dav pom cov khoom lag luam yuav ntim lossis xa tawm kom tshem tawm cov khoom tsis raug (cov khoom tsis raug suav nrog cov hniav puas, cov khoom sib xyaw, xeb, thiab lwm yam). Lwm txoj kev yog tag nrho tsis siv neeg tshawb pom los ntawm lub tshuab, feem ntau sib nqus particle flaw nrhiav. Magnetic particle flaw detection siv cov kev sib cuam tshuam ntawm cov xaim hlau nplaum thiab cov hmoov sib nqus ntawm qhov tsis xws luag ntawm lub ntsia liaj qhov rooj. Raws li qhov sib txawv ntawm qhov sib nqus permeability thiab steel permeability ntawm qhov ua tau tsis zoo (xws li cov kab nrib pleb, slag suav nrog, cov khoom sib xyaw, thiab lwm yam) ntawm cov ntsia liaj qhov rooj, cov khoom sib nqus ntawm qhov tsis sib xws ntawm cov ntaub ntawv no yuav raug distorted tom qab magnetization, tsim kom muaj dej ntws. magnetic teb nyob rau saum npoo ntawm lub workpiece qhov twg ib co sib nqus flux leaks, yog li attracting magnetic hmoov los tsim magnetic hmoov tsub zuj zuj ntawm qhov tsis xws luag - magnetic traces. Nyob rau hauv cov teeb pom kev zoo tsim nyog, qhov tsis xws luag txoj hauj lwm thiab cov duab raug nthuav tawm. Kev sib txuam ntawm cov hmoov sib nqus no tau pom thiab txhais kom ua tiav lub hom phiaj ntawm kev tshem tawm cov khoom tsis raug. Taw qhia rau tooj dag bolts: Force hom: Ordinary thiab nrog remed qhov. Ordinary bolts feem ntau dais axial rog, thiab tuaj yeem dais sab nraud nrog cov kev xav tau tsawg. Cov bolts siv rau qhov remed yuav tsum phim qhov loj ntawm lub qhov thiab yog siv thaum raug rau lateral quab yuam.
Taw qhia rau cov duab ntawm tooj dag bolts:
Feem ntau, countersunk taub hau yog siv nyob rau hauv qhov chaw uas qhov chaw yuav tsum tau du thiab tsis muaj protrusions tom qab kev twb kev txuas, vim hais tias lub countersunk taub hau yuav screwed rau hauv qhov chaw. Round taub hau kuj tuaj yeem ntsia tau rau hauv qhov chaw. Lub zog nruj ntawm lub taub hau square tuaj yeem loj dua, tab sis qhov loj me yog qhov loj.
Tsis tas li ntawd, txhawm rau ua kom tau raws li qhov xav tau ntawm kev kaw haujlwm tom qab kev teeb tsa, muaj qhov nyob hauv lub taub hau thiab qhov nyob hauv tus pas nrig. Cov qhov no tuaj yeem tiv thaiv cov bolts los ntawm loosening thaum vibrating.
Qee cov bolts tsis muaj xov liab qab thiab ua nyias, hu ua nyias lub duav bolts. Hom bolt no yog qhov tsim nyog rau kev sib txuas nrog lub zog sib txawv.
Muaj tshwj xeeb high-strength bolts ntawm cov qauv steel, lub taub hau yuav loj dua, thiab qhov loj yuav txawv.
Tsis tas li ntawd, muaj kev siv tshwj xeeb: T-slot bolts, uas feem ntau yog siv los ntawm cov cuab yeej siv tshuab, nrog cov duab tshwj xeeb, thiab ob sab ntawm lub taub hau yuav tsum raug txiav tawm. Thauj tog rau nkoj bolts, siv los txuas thiab kho cov cav tov rau hauv av, muaj ntau yam duab. U-shaped bolts, raws li tau hais los saum toj no. Thiab li ntawd.
Kuj tseem muaj cov studs tshwj xeeb rau vuam, ib kawg ntawm cov xov thiab lwm qhov kawg tsis. Lawv tuaj yeem raug welded rau qhov chaw thiab cov txiv ntseej tuaj yeem ncaj qha screwed ntawm lwm sab.
