Puas yog 40mm Rebar Bender yeej khoov tau txhua 40mm Bar?

Thaum xub thawj siab ib muag, cov lus teb zoo li pom tseeb. Yog tias lub tshuab raug muag ua 40mm rebar bender , nws yuav tsum khoov ib daim hlau 40mm. Hauv kev xyaum, qhov kev xav ntawd tuaj yeem ua rau cov neeg yuav khoom muaj teeb meem. Lub cheeb tsam luam tawm ntawm daim ntawv qhia tshwj xeeb feem ntau yog hais txog cov khoom siv tshwj xeeb thiab qhov xwm txheej sim. Hloov qib hlau, hom hlau lossis geometry khoov, thiab lub peev xwm siv tau kuj tuaj yeem hloov pauv thiab. Qhov no yog vim li cas ob daim hlau ntsuas raws nraim 40mm hla yuav tsis tso tib qhov kev thov rau ntawm lub tshuab khoov hlau .

Twb muaj ntau yam khoom siv tiag tiag uas qhia txog qhov txawv lawm. Ib lub tshuab khoov 40mm uas muag tau raug ntsuas rau 40mm Qib 240 reinforcement tab sis tsuas yog 32mm Qib 400 bar xwb. Qhov ntawd yog qhov txo qis 20% ntawm txoj kab uas tso cai yam tsis tau hloov lub tshuab nws tus kheej. Cov hlau tau hloov pauv; lub peev xwm ua tau hloov pauv nrog nws.

Qhov ntsuas 40 hli muaj txiaj ntsig zoo, tab sis nws yuav tsum raug suav hais tias yog qhov pib ntawm kev kuaj xyuas cov lus qhia es tsis yog qhov kawg ntawm nws. Cov neeg yuav khoom yuav tsum nug ib txwm cov khoom siv uas daim duab hais txog. Puas yog nws yog hlau puag ncig? Cov hlau txhawb nqa deformed? Siv qib hlau twg?

Piv txwv li, CAMCO teev ib lub tshuab GW40 nrog qhov khoov ntawm 6–40mm rau cov hlau puag ncig, thaum Qib II deformed bar tsuas yog txwv rau 6–32mm. Qhov sib txawv 8mm ntawd tseem ceeb. Tus neeg yuav khoom uas nyeem tsuas yog tus lej loj "40mm" tuaj yeem yooj yim xav tias muaj peev xwm uas cov lus qhia ntxaws tsis tau cog lus tiag tiag.

Yog li thaum tus neeg muag khoom hais tias, "Lub tshuab no khoov 40mm hlau," qhov kev ua raws li qhov tsim nyog tsuas yog: "40mm hlau twg?" Ib lo lus nug ntawd tuaj yeem txuag tau ntau qhov kev sib tham tsis meej tom qab lub tshuab tuaj txog ntawm qhov chaw.

Txoj kab uas hla qhia koj tias tus pas loj npaum li cas, tab sis nws tsis qhia koj tias cov khoom siv tiv taus kev hloov pauv tau zoo npaum li cas. Cov khoom siv txhawb nqa uas muaj zog dua feem ntau yuav tsum siv zog ntau dua los tsim, yog vim li cas ntau lub tuam txhab tsim khoom muab cov kev txwv sib txawv rau cov qib sib txawv.

Ib qho piv txwv pab tau los ntawm cov lus qhia tshwj xeeb ntawm TMG hluav taws xob rebar bender. Lub tshuab no tau ntsuas rau 40mm Qib 240 reinforcement tab sis tsuas yog 32mm Qib 400 xwb. Tib tus qauv kuj muaj qhov ntau thiab tsawg ntawm 0–180 ° bending, ±1 ° qhia qhov tseeb ntawm lub kaum sab xis thiab disc speeds ntawm 5 thiab 10rpm. Cov lej ntawd ua rau cov lus qhia tshwj xeeb muaj txiaj ntsig ntau dua li daim ntawv lo "40mm siab tshaj plaws" vim tias lawv qhia tus neeg yuav khoom txog ob qho tib si peev xwm thiab kev tswj hwm.

Rau cov neeg ua haujlwm thiab cov khw tsim cov hlau rebar, zaj lus qhia yooj yim heev: phim lub tshuab kom haum rau cov sijhawm ua haujlwm tiag tiag. Yog tias qhov project feem ntau siv cov hlau muaj zog dua, qhov loj tshaj plaws uas tau tshaj tawm yuav tsis yog qhov loj tshaj plaws uas koj yuav tsum siv rau kev xaiv tshuab.

Qhov no yog lwm qhov ua rau muaj kev tsis meej pem. Qee cov ntawv teev khoom siv cov kab lus "steel bar bending capacity", thaum lub project nws tus kheej siv deformed reinforcement. Cov ntawd tsis yog cov qib sib npaug.

Ib lub tshuab yuav ua tau yooj yim tuav ib lub pas hlau puag ncig 40 hli thiab tseem muaj qhov txwv qis dua rau cov hlau deformed. Qhov sib txawv tuaj yeem los ntawm qib hlau thiab txoj kev uas lub tshuab tau raug ntsuas. Yog vim li cas cov pab pawg yuav khoom yuav tsum nrhiav cov lus tseeb hauv cov lus qhia es tsis txhob cia siab rau lub npe khoom xwb.

Hauv lwm lo lus, "40mm steel bar" thiab "40mm reinforcing bar" yuav zoo li zoo ib yam hauv phau ntawv qhia, tab sis rau lub gearbox lawv tuaj yeem yog cov neeg siv khoom sib txawv heev.

Lub zog tsuas yog ib feem ntawm txoj haujlwm xwb. Tus pas nrig kuj yuav tsum tau khoov ib ncig ntawm tus thawj lossis mandrel kom raug. Kev khoov nruj heev ua rau muaj kev nyuaj siab hauv cov hlau, yog li cov qauv kev txhawb nqa teeb tsa cov kev txwv ntawm qhov geometry khoov es tsis pub tus pas nrig raug qhwv ib ncig ntawm txhua tus pin uas tshwm sim kom haum rau lub tshuab.

Cov lus qhia txog Eurocode 2 siv qhov tsawg kawg nkaus ntawm txoj kab uas hla ntawm lub mandrel ntawm 4 npaug ntawm txoj kab uas hla ntawm lub bar rau kev txhawb nqa txog li 16 hli thiab 7 npaug ntawm txoj kab uas hla ntawm lub bar rau cov tuav loj dua thaum kuaj xyuas kev puas tsuaj rau kev txhawb nqa. Rau 40 hli bar, 7 × 40 hli muab txoj kab uas hla ntawm lub mandrel ntawm 280 hli ua ntej yuav tsum xav txog kev kuaj xyuas tshwj xeeb ntxiv rau qhov project.

Tus lej ntawd tsim nyog nco ntsoov. Lub tshuab muaj peev xwm muaj lub zog txaus los txav lub bar 40mm thiab tseem tsis haum rau qhov khoov uas xav tau yog tias tsis muaj cov cuab yeej raug. Thaum xaiv lub tshuab khoov rebar 40mm , cov pins, rollers thiab formers tsim nyog tau txais kev saib xyuas yuav luag zoo ib yam li lub zog ntawm lub cev muaj zog.

Kev ua haujlwm tsim khoom ntxiv ib txheej ntxiv rau lo lus nug txog lub peev xwm. Cov chaw tsim khoom feem ntau khoov ntau lub pas hlau hauv tib lub voj voog, yog li qhov siab tshaj plaws ntawm ib lub pas hlau tsis qhia tag nrho zaj dab neeg.

Ib lub tshuab B55-S muag hauv UK yog teev rau ib qho 40mm bar, ob 32mm bars lossis peb 25mm bars. Nws siv lub cev muaj zog peb theem 5.5kW thiab muaj qhov ceev ntawm 6rpm. Qhov ntawd yog ib txoj hauv kev zoo dua los piav qhia txog lub peev xwm ua haujlwm vim nws qhia tau tias lub tshuab ua haujlwm li cas hauv qab kev sib xyaw ua ke ntawm ntau yam bars.

Rau ib qho chaw uas tsuas yog ua qhov nkhaus loj qee zaum xwb, qhov loj tshaj plaws ntawm txoj kab uas hla yuav yog qhov teeb meem tseem ceeb. Rau ib lub chaw ua haujlwm tsim cov tawb thoob plaws hnub, qhov ceev ntawm lub voj voog, qhov rov ua dua tau thiab lub peev xwm ntau ntawm ntau qhov bar sai sai los ua qhov tseem ceeb ib yam.

Txoj kev nyab xeeb tshaj plaws yog pib nrog daim ntawv teev sijhawm ua hlau es tsis txhob sau cov ntawv teev khoom ntawm lub tshuab. Sau qhov loj tshaj plaws ntawm txoj kab uas hla ntawm cov hlau, qib hlau, qhov loj ntawm cov hlau ib txwm siv txhua hnub, lub kaum sab xis uas xav tau thiab qhov loj ntawm txoj kab uas hla ntawm cov hlau. Tom qab ntawd saib seb cov hlau loj tshaj plaws tshwm sim ntau npaum li cas hauv kev tsim khoom.

Yog tias siv cov khoom siv reinforcement 40mm tsuas yog qee zaum xwb thiab feem ntau cov haujlwm txhua hnub yog nyob rau hauv qhov ntau ntawm 16–25mm, lub tshuab bender rebar 40mm uas raug ntsuas kom zoo yuav yog qhov haum. Yog tias 40mm lub bar muaj zog siab yog ib feem ntawm kev tsim khoom txhua hnub, kev hloov mus rau chav kawm tshuab loj dua yuav ua rau tus neeg teb xov tooj ua haujlwm ntau dua es tsis txhob khaws lub tshuab ntawm qhov kawg saum toj kawg nkaus ntawm nws cov ntau yam luam tawm txhua hnub.

Yuav tsum tau kuaj xyuas qhov voltage, lub cev muaj zog, qhov ceev ntawm kev khoov, cov cuab yeej, cov khoom seem thiab kev pabcuam ua ntej yuav. Lawv tsis tshua muaj kev zoo siab npaum li tus lej loj ntawm nplooj ntawv pem hauv ntej, tab sis feem ntau lawv tseem ceeb dua tom qab rau lub hlis ntawm kev ua haujlwm tiag tiag.

Lub ntsiab lus tseem ceeb yog yooj yim: lub peev xwm khoov rebar yog kev sib xyaw ua ke ntawm txoj kab uas hla ntawm cov hlau, qib hlau, cov cuab yeej thiab cov xwm txheej ua haujlwm . Daim ntawv lo 40mm muaj txiaj ntsig zoo, tab sis nws yuav tsum tsis txhob yog tus lej nkaus xwb uas siv los txiav txim siab yuav khoom.
