Q1: Vim li cas burrs daim ntawv tom qab txiav galvanized xim -coated steel coils?
Kev tsim ntawm burrs yog feem ntau cuam tshuam nrog txoj kev txiav thiab cov khoom siv:
Txoj kev txiav tsis raug: Thaum siv txiab txiab, hluav taws xob txiab, los yog cov hniav, cov hniav tsis tuaj yeem ntxuav kom huv si los ntawm cov galvanized thiab xim -coated txheej, tab sis es tsis txhob kua muag thiab stretches, tsim tsa burrs lossis curled npoo.
Cov ntaub ntawv toughness: galvanized steel ntawv substrate muaj qee qhov kev ductility; yas deformation thaum txiav yuav exacerbate burr tsim.
2.Dab tsi yog qhov txaus ntshai ntawm burrs?
Scratch Risk: Ntse burrs tau yooj yim txiav tus neeg teb xov tooj txhais tes thiab kos cov xim pleev xim ntawm cov vaj huam sib luag uas nyob ib sab.
Txheej Kev puas tsuaj: Cov txheej txheej ntawm qhov chaw burr twb puas lawm, poob nws txoj haujlwm tiv thaiv thiab ua qhov pib ntawm xeb.
Kev sib txuas tsis zoo: Thaum lub sij hawm tom qab riveting los yog overlapping, burrs tuaj yeem tiv thaiv cov vaj huam sib luag kom nruj, cuam tshuam rau kev sib khi.
Txheej Obstacles: Yog tias nws yuav tsum siv cov tshuaj tiv thaiv- xeb xim rau qhov chaw txiav, burrs yuav ua rau cov xim tsis sib xws.
Q3: Yuav ua li cas tiv thaiv xeb ntawm ntug txiav tom qab deburring? Yuav tsum kho li cas?
Deburring tsuas yog thawj kauj ruam. Cov txheej galvanized thiab xim txheej ntawm ntug txiav tau raug puas ntsoog, nthuav tawm cov khoom siv hauv paus (txias-cov hlau dov) ncaj qha. Kev tiv thaiv xeb yog qhov tseem ceeb.
Cov txheej txheem tiv thaiv xeb txheej txheem (Peb-txoj kev:
Ntxuav Ntug Ntug: Siv daim ntaub huv los yog txhuam kom tshem cov hmoov hlau thiab hmoov av thaum sib tsoo. Yog tias qhov txiav ntug yog oily, so nrog cawv los yog acetone thiab cia nws qhuav.
Siv Cov Tshuaj Tiv Thaiv Tiv Thaiv: Siv zinc- nplua nuj primer (zinc cov ntsiab lus tsis tsawg dua 70%) lossis epoxy zinc-nplua nuj primer, thiab siv nws sib npaug rau qhov txiav nrog txhuam zoo. Zinc-nplua nuj primer muab kev tiv thaiv cathodic, tiv thaiv cov khoom siv los ntawm xeb txawm tias cov txheej txheej puas me ntsis. Rau qhov tsis yog- qhov chaw tseem ceeb, ceev- ziab xeb- cov xim tiv thaiv (xws li cov hlau lead rust-tiv thaiv xim) kuj tseem siv tau, tab sis cov nyhuv tiv thaiv tsis zoo li zinc{11}} nplua nuj primer.
Kev kho sab saum toj (yeem): Yog tias qhov sib xws ntawm cov tsos thiab xim yog qhov yuav tsum tau ua, tom qab cov primer qhuav lawm, kho cov xim zoo ib yam lossis cov xim zoo sib xws li xim -coated yob (hauv aerosol tuaj yeem lossis lub raj mis me) tuaj yeem txau los yog txhuam rau saum npoo. Nco ntsoov tias cov xim kho yuav tsum sib haum nrog cov primer.
Q4: Yuav ua li cas kom tsis txhob ua kom puas cov xim nyob ib puag ncig thaum tshem tawm burrs thiab txiav?
Thaum cov xim txheej yog khawb, nws poob nws lub peev xwm tiv thaiv. Yog li ntawd, kev saib xyuas ntxiv yog xav tau thaum tshem tawm burrs:
Xaiv cov cuab yeej raug thiab siab:
Siv cov ntaub ntawv zoo-cov hniav (1-1.5mm hniav pitch) es tsis txhob coarse- cov ntaub ntawv hniav, thiab cov ntaub ntawv nyob rau hauv ib qho kev taw qhia nkaus xwb, tsis txhob rov qab -thiab-tawm sawing kev sib txhuam.
Thaum siv cov scraper, cov hniav yuav tsum txhuam los ntawm cov kev taw qhia ntawm cov xim txheej ntawm cov burr, tsis yog lwm txoj hauv kev, txhawm rau tiv thaiv cov hniav ntawm qhov ntxig rau hauv cov xim txheej thiab ua rau nws tev tawm.
Thaum siv cov ntawv xuab zeb, tsuas yog xuab zeb rau thaj tsam ntawm cov burr, tsis txhob loj - thaj tsam kev sib txhuam ntawm cov xim pleev xim.
Siv cov yeeb yaj kiab tiv thaiv:
Ua ntej- siv daim npog ntsej muag lossis PVC tiv thaiv zaj duab xis 10-15mm ntawm txoj kab txiav ntawm ob sab. Tshem tawm cov yeeb yaj kiab tiv thaiv tsuas yog tom qab tshem cov burrs thiab ua tiav cov duab. Qhov no zoo tiv thaiv cov cuab yeej los ntawm kev khawb qhov chaw nyob ib sab.
Q5: Puas muaj txoj kev txiav zoo dua uas tuaj yeem txo lossis tsis txhob burrs los ntawm qhov chaw?
Factory Prefabrication: Zoo dua yog siv lub tshuab shearing lossis voj voog. Tom qab txiav, deburring yuav luag tsis tsim nyog; tsuas yog yuav tsum tau ua kom tiav.
Ntawm -Qhov Kev Tsim Kho: Yog tias tsuas yog siv hluav taws xob lossis phau ntawv txiav tuaj yeem siv tau, nco ntsoov npaj cov ntawv txhuam lossis cov ntaub ntawv zoo rau kev tshem tawm.
Tsis txhob siv: Ib qho yooj yim hacksaws thiab jigsaws (hlau pom hniav) yuav tsim kom muaj ntau qhov burrs thiab kub kub, ua rau cov txheej txheem loj heev; lawv yuav tsum zam kiag li.
