Txhua lub laj kab muaj qhov nkag, uas, raws li txoj cai, muaj lub rooj vag thiab lub rooj vag. Cov laj kab no feem ntau yog cov laj kab kim tshaj plaws vim qhov nyuaj ntawm lawv cov khoom siv thiab kev teeb tsa. Txawm li cas los xij, hauv qhov no, nws muaj peev xwm txuag tau nyiaj los ntawm kev ua lub rooj vag thiab lub rooj vag los ntawm cov yeeb nkab profile nrog koj tus kheej tes.
Qhov zoo ntawm cov yeeb nkab profile raws li cov khoom siv rau rooj vag
Profile yeeb nkab yog ib qho ntawm cov khoom siv nyiaj txiag zoo tshaj plaws nrog lub zog zoo, kev ntseeg siab thiab kev ua haujlwm ntev. Tus nqi ntawm cov yeeb nkab kws tshaj lij tsis tuaj yeem hu ua qis. Txawm li cas los xij, cov yam ntxwv ntawm kev ua haujlwm ntawm qhov profile, nrog rau qhov muaj peev xwm ntawm kev tsim cov qauv los ntawm nws yam tsis muaj kev koom nrog cov neeg ua haujlwm ntxiv, tag nrho them nyiaj rau tus nqi ntawm cov khoom siv raw. Qhov no tso cai rau peb los muab cov khoom siv no rau hauv qeb ntawm qhov kev lees paub tshaj plaws txhawm rau ua lub rooj vag los ntawm cov yeeb nkab profile nrog koj tus kheej tes.
Txhua yam koj xav tau yog qhov tsawg kawg nkaus muaj peev xwm ua haujlwm nrog lub tshuab sib tsoo thiab vuam, nrog rau qee qhov kev paub hauv cov duab kos.
Gate drawing
Ua ntej pib nrog kev tsim cov qauv, nws yog ib qho tsim nyog yuav tsum xub kos ib daim duab ntawm lub rooj vag los ntawm cov yeeb nkab profile. Ua ntej, qhov noyuav tso cai rau koj kom raug xam raws li qhov xav tau ntawm cov khoom siv. Thib ob, nws yuav lav qhov kev txhim kho kom raug, tsis muaj kev cuam tshuam thiab zoo nkauj zoo nkauj.
Thawj pib, nws yog qhov yuav tsum tau ua txhua qhov kev ntsuas, raws li cov duab kos. Qhov kev tshwm sim no suav nrog ntsuas qhov sib txawv ntawm qhov kev txhawb nqa thiab suav thaj tsam ntawm ntug hiav txwv sash. Los ntawm txoj kev, txawm tias thaum lub sij hawm tsim kho ntawm lub laj kab, nws yog ib qhov tsim nyog yuav tsum tau muab cov ncej uas lub rooj vag los ntawm cov yeeb nkab profile yuav txuas nrog, ntawm qhov deb txaus rau kev nkag mus rau lub tsheb lossis lwm yam khoom siv. Tsis tas li ntawd nco ntsoov tias muaj qhov chaw txaus rau qhov qhib tag nrho ntawm lub qhov rooj yav tom ntej.
Xaiv nta
Thaum npaj lub rooj vag, nco ntsoov xav txog qhov cua ntawm cov khoom. Yog tias cov qauv nyob rau ntawm thaj chaw uas tau tawg yooj yim, cov sashes tsis pom zoo kom ua kom loj thiab ua los ntawm cov khoom siv. Qhov tseeb yog hais tias nyob rau hauv cov ntaub ntawv no, lub load ntawm tus ncej yuav nce ho, uas txhais tau hais tias lub rooj vag ntawm lub profile yeeb nkab yuav tsum tau ntxiv dag zog rau. Qhov no yuav ua rau muaj kev nce nqi ntawm lub laj kab thiab ntau txoj haujlwm kev teeb tsa. Yog li ntawd, nws yog qhov zoo dua los siv cov khoom siv hauv tsev xws li mesh lossis grating.
Dab tsi yuav tsum tau ua yog xam qhov ntev ntawm cov tis kom lawv sib koom ua ke ywj siab. Yog tias tom qab lub rooj vag los ntawm cov yeeb nkab profile yuav raug sheathed nrog corrugated board, nws raug nquahu kom coj mus rau hauv tus account tus naj npawb ntawm stiffeners ntawm txhua nplooj kom lawv tsis txhob cling rau ib leeg.
Yog tias cov yeeb nkab zoo li yuav ua lub thav duab rau lub vev xaib sheathing, xyuas kom nws haum rau hauv qhov chaw.
Kev xaiv cov khoom siv rau kev tsim cov rooj vag
Tom qab kos duab ntawm lub rooj vag yav tom ntej, nws yog qhov tsim nyog los suav cov khoom siv. Nyob rau tib lub sijhawm, ib yam li kev tsim kho ntawm lwm cov qauv, nco ntsoov ua kom muaj peev txheej ntawm 10% rau qhov xwm txheej tsis tau pom dua.
rooj vag los ntawm cov yeeb nkab profile tuaj yeem ua los ntawm cov khoom sib txawv: round, rectangular los yog square.
Ob txoj kev xaiv kawg yog kev lag luam tshaj plaws, lawv siv cov khoom siv me ntsis tsawg dua rau cov kav dej. Lwm qhov kom zoo dua ntawm cov yeeb nkab square lossis duab plaub yog tias txawm tias tus neeg siv khoom tshiab tuaj yeem ua haujlwm nrog cov khoom siv no, vim nws yooj yim dua rau vuam rooj vag los ntawm cov yeeb nkab profile nrog sab ncaj.
Tsis tas li ntawd, tsis txhob hnov qab txog qhov loj ntawm cov kav dej. Feem ntau siv cov kav dej uas muaj ntu ntawm 40 x 20 mm lossis 50 x 50 mm yog siv. Txawm li cas los xij, tsis txhob hnov qab txog cov cua thauj khoom ntawm cov qauv, qee zaum nws yuav tsum siv qhov loj dua, piv txwv li 60 x 30 mm.
Gate manufacturing process
Tau kawg, thawj qhov uas yuav tsum tau ua yog npaj tag nrho cov cuab yeej tsim nyog thiab cov khoom siv rau kev ua haujlwm. Yog hais tias cov yeeb nkab profile yog them nrog xeb, nws yuav tsum tau ntxuav thiab degreased, thiab ces txiav mus rau hauv pieces ntawm qhov ntev yuav tsum tau. Qee cov neeg tsim khoom tam sim ntawd npog cov khoom siv nrog primer thiab tiv thaivmuaj pes tsawg leeg. Tab sis thaum lub sij hawm vuam, cov khoom txheej yuav raug puas, yog li nws yog qhov zoo dua los ua cov txheej txheem tom qab kev teeb tsa.
Feem ntau cov lus nug tshwm sim ntawm yuav ua li cas txuas lub rooj vag los ntawm cov yeeb nkab profile. Qhov tseem ceeb tshaj plaws yog saib xyuas cov cuab yeej siv thiab ua ntu zus ntawm kev ua haujlwm vuam. Kev ua hauj lwm yuav tsum tau ua nyob rau hauv ib qho chaw ruaj khov, tiaj tus uas tsis raug rau qhov hluav taws kub. Hauv qhov no, lawv siv lub ntsej muag tiv thaiv lossis tsom iav, hnab looj tes, thiab xaiv cov khaub ncaws ua los ntawm cov ntaub ntom ntom ua khaub ncaws.
Sash welding xaj
Cov txheej txheem vuam tag nrho siv sijhawm me ntsis thiab ua tiav raws li cov thev naus laus zis ntawm txoj haujlwm no. Ua ntej welding lub ntsiab nrog ib tug nruam seam, lawv yog preliminarily tacked los ntawm qhov chaw vuam. Tom qab ntawd, qhov tseeb ntawm qhov ntev ntawm qhov chaw tsim khoom raug kuaj xyuas. Yog tias txhua yam ua tiav yog lawm, vuam seam yog ua, uas yog tom qab hauv av.
Ua ntej, tus ncej lossis thav duab ntawm lub rooj vag yog welded ntawm cov ces kaum, thaum nws yog qhov tsim nyog los xyuas kom meej tias ob lub tis nyob hauv tib lub dav hlau. Xwb, ib qho thav duab yog thawj welded, uas yog tom qab txiav hauv nruab nrab. Txoj hauv kev no lav qhov tseeb ntawm kev ua raws li qhov yuav tsum tau muaj qhov ntev ntawm lub li qub.
Tom qab cov thav duab tau tsim, lawv yuav tsum tau ntxiv dag zog. Ua li no, ntxiv stiffeners los ntawm tib qhov profile yog welded rau lub ntsiab ncej, thiab daim duab peb sab hlau yog welded rau cov ces kaum.
Lwm qhov tseem ceeb yog qhov vuam ntawm lub voj voog. Ua ntej, ib nrab ntawm cov khoom no txuas ncaj qha raurooj vag. Qhov thib ob halves yog muab tso rau thiab, tau txuas lub sash ntawm qhov siab xav tau, qhov qis ntawm cov pob khawm yog welded rau cov kev txhawb nqa. Rau txoj haujlwm no, nws yog qhov zoo dua los caw lwm tus neeg uas yuav kho lub rooj vag hauv qhov xav tau thaum tacking lub hinges.
Tom qab tag nrho cov kev sib tsoo thiab kev sib tsoo ntawm cov seams, cov thav duab tiav yog them nrog tus neeg sawv cev tiv thaiv. Nws tuaj yeem ua kua roj vanish, mastic lossis xim. Tom qab ntawd, koj tuaj yeem mus rau sheathing lub thav duab nrog cov khoom siv hauv tsev.
