Roll forming tshuabyog dav siv nyob rau hauv zus tau tej cov ntau yam tsim hlau profiles. Cov chais yog cov khoom tseem ceeb uas tuaj rau hauv kev sib cuag ncaj qha nrog cov khoom thiab dais lub siab tsim; lawv qhov zoo tsis tsuas yog txiav txim siab ncaj qha rau qhov tseeb thiab qhov zoo ntawm cov ntawv tiav tab sis tseem cuam tshuam rau lub tshuab ua haujlwm ruaj khov, tsis ua haujlwm, thiab tag nrho cov kev pabcuam lub neej.
Xaiv lub siab- cov menyuam rollers zoo yog li tseem ceeb heev rau kev txo cov nqi khiav lag luam thiab kev saib xyuas, txuas ntxiv lub tshuab yob txoj kev pabcuam lub neej, thiab ua kom muaj kev ua haujlwm zoo ntawm cov kab ntau lawm.
Raws li cov chaw tsim khoom lag luam thiab cov khoom lag luam nrog xyoo dhau los hauv kev lag luam, KINGREAL Roll Former tau txais kev lees paub thoob ntiaj teb rau kev tsim khoom siv technology thiab cov qauv nruj rau kev xaiv cov khoom. Lub sijhawm ntev -, kev ua haujlwm ruaj khov ntawm lub tshuab yob txoj kev vam khom rau qhov zoo ntawm cov tub ntxhais cov menyuam; kab lus no muab cov ncauj lus kom ntxaws txog qhov siab npaum li cas - rollers zoo txhim kho lub neej kev pab cuam ntawm yob txoj kev tshuab.
Taw qhia rau Roll Forming Tshuab Rollers
Txoj kev tsim ntawm ayob txoj kev tshuabtso siab rau kev sib koom ua ke ntawm kev ua tiav cov menyuam. Cov cuab yeej siv feem ntau muaj ntau txoj kab rov tav cov menyuam sawv ntsug thiab ncaj cov menyuam sawv ntsug. Nyob ntawm qhov profile qhov nyuaj thiab ntoo khaub lig- cov kev xav tau ntawm ntu, auxiliary forming rollers, ntsug rollers, thiab cov khoom siv tshwj xeeb tau muab tso ua ke. Cov ntau hom rollers no ua haujlwm hauv kev hais kwv txhiaj, txhua tus muaj lub luag haujlwm tshwj xeeb, kom ntseeg tau tias yob txoj kev tshuab ua haujlwm tas li thiab ruaj khov.
Kab rov tav rollers ua haujlwm tseem ceeb ntawm kev tsav tsheb thiab tsim cov khoom siv. Mounted ntawm lub ntsiab tsav, lawv tuav cov haujlwm tseem ceeb ntawm kev khoov, compacting, thiab shaping cov hlau ntawv, ua rau lawv tseem ceeb Cheebtsam uas muaj kev ntxhov siab thiab ua haujlwm tas mus li. Auxiliary rollers yog cov khoom siv ua ntu zus, feem ntau ntsia nruab nrab ntawm cov menyuam kab rov tav los yog teeb tsa hauv pab pawg. Lawv hais txog thaj chaw tshwj xeeb-xws li "cov qhov muag tsis pom kev" lossis cov zawj- cov kab rov tav kab rov tav tsis tuaj yeem ua kom zoo, yog li ua kom muaj qhov sib txawv. Lawv kuj pab txo tus naj npawb ntawm txoj kev hla yuav tsum tau los ntawm kab rov tav rollers, yog li txo qis kev ua haujlwm ntawm lub tshuab lub ntsiab rollers.
Vertical rollers yog ntsia rau tib lub dav hlau kab rov tav raws li cov menyuam kab rov tav hla. Lawv feem ntau yog lub luag haujlwm rau ntug shaping thiab calibration thaum lub sij hawm kawg ntawm cov txheej txheem tsim, kom ntseeg tau qhov ncaj ntawm qhov profile sab thiab qhov sib xws.
Kev cuam tshuam tseem ceeb ntawm Cov Menyuam Zoo ntawm Roll Forming Machine
Thaum lub sij hawm tas mus li txheej txheem ntau lawm ntawmyob txoj kev tshuab, rollers raug kev sib txhuam tas li thiab siab tiv thaiv cov ntawv hlau, ua rau lawv cov khoom cuam tshuam ncaj qha los ntawm kev hnav thiab tsim kua muag; lawv qhov zoo ncaj qha txiav txim siab lub tshuab kev ua haujlwm thiab kev pabcuam lub neej. High- cov menyuam ua haujlwm zoo ua kom muaj kev sib koom ua ke, tsis muaj kev puas tsuaj rau cov khoom siv ntawm cov ntawv hlau, tiv thaiv ntau yam teeb meem thaum lub sijhawm ua haujlwm. Ntawm ib sab tes, lawv xyuas kom meej qhov tseeb qhov tseeb, tshem tawm qhov sib txawv ntawm cov khoom tiav, thiab txo qis qhov tsis xws luag xws li khawb, wrinkles, thiab deformation.
Ntawm qhov tod tes, lawv muaj txiaj ntsig zoo tiv thaiv cov teeb meem ntau lawm xws li strip misalignment thiab tsis sib xws kev ntxhov siab, ua rau lawv haum rau siab -ceev, nruam ntau lawm hom ntawm yob txoj kev tshuab.
Qhov tseem ceeb tshaj, siab -cov rollers zoo sib npaug faib lub tshuab ua haujlwm, txo qhov cuam tshuam thiab hnav ntawm tus ncej, bearings, thiab kis tau tus mob. Qhov no tsis yog tsuas yog txuas ntxiv lub neej kev pabcuam ntawm cov cuab yeej tab sis kuj ua kom muaj txiaj ntsig zoo sib xws nyob rau hauv cov khoom siv thiab ua kom ruaj khov ntau lawm.
Conversely, inferior rollers yog thawj qhov ua rau muaj kev ua haujlwm tsis zoo thiab ua haujlwm luv luv rau cov tshuab yob txoj kev. Cov menyuam yaus tsis muaj qhov tseeb, hnav tsis kam, lossis qhov tawv txaus tuaj yeem ua rau muaj teeb meem zoo thaum lub sijhawm ua haujlwm -xws li ntug tawg, khawb qhov chaw, strip misalignment, thiab profile twisting lossis deformation- ncaj qha ua rau cov khoom seem thiab txo cov khoom lag luam. Tsis tas li ntawd, cov menyuam yaus tsis zoo yog qhov ua rau deformation nyob rau hauv kev thauj khoom thiab hnav sai sai, yuav tsum tau saib xyuas thiab hloov ntau zaus. Qhov no tsis yog tsuas yog ua rau cov khoom siv ua haujlwm thiab cov nqi tu tab sis kuj ua rau lub sijhawm ua haujlwm tsis tu ncua; rov pib thiab nres nrawm nrawm ntawm cov qauv sib kis thiab thav duab. Ntev- siv lub sij hawm ua rau muaj tseeb drift thiab ceev tivthaiv kev laus, drastic shortening lub tshuab tag nrho lifespan.
Common High-Quality Roller Materials rauYobKev Ua Tshuab
Cov txheej txheem ua haujlwm sib txawv, cov ntaub ntawv, thiab cov txheej txheem tsim muaj ntau qhov kev xav tau sib txawv ntawm qhov hardness, hnav tsis kam, toughness, thiab siab -kub tsis kam ntawm yob txoj kev tshuab rollers. Kev xaiv meej ntawm cov khoom siv rau cov menyuam yog ib kauj ruam tseem ceeb hauv kev ua kom zoo thiab ua kom lub tshuab ua haujlwm ntev. Txhawm rau ua kom tau raws li qhov xav tau ntawm ntau yam kev ua haujlwm, KINGREAL Roll Former xaiv los ntawm ntau yam siab - cov hlau zoo li cov ntaub ntawv hauv paus rau nws cov menyuam -xws li 45# Steel, GCr15, Cr12, Cr12MoV, D2, thiab SKD11- kom ntseeg tau tias tsim nyog rau ntau yam yob txoj kev tsim cov scenarios.
45 # Hlaunta cov ntsiab lus carbon ntawm 0.42% -0.5% thiab cov ntsiab lus chromium tsawg dua lossis sib npaug li 0.25%; Tom qab kev kho cua sov, nws ua tiav qhov hardness ntawm 56-59 HRC. Rollers ua los ntawm cov khoom siv no muaj cov khoom siv zoo heev, nrog rau lub zog txaus thiab kev ua haujlwm zoo. Nrog rau qhov sib npaug ntawm cov tawv nqaij thiab cov yas ua tiav los ntawm kev quenching thiab tempering, lawv yog qhov zoo tagnrho rau kev tsim cov qauv ntawv hlau ntawm chav tsev kub thiab ua tau raws li cov kev xav tau ntawm kev ua haujlwm yooj yim ntawm cov pa yob txoj kev tshuab, muab cov nqi siab - ua tau zoo thiab tsis kam mus rau chipping lossis breakage.
GCr15yog ib qho siab -carbon chromium bearing steel nrog cov ntsiab lus carbon ntawm 0.95% -1.05% thiab cov ntsiab lus chromium ntawm 1.3% -1.65%, ncav cuag hardness ntawm 61-66 HRC tom qab kev kho cua sov. Tom qab quenching thiab qis - kub tempering, cov khoom muaj ib tug niaj hnub microstructure, hardness siab, thiab muaj zog hnav tsis kam, nrog rau zoo heev qaug zog thiab tiv tauj- compression kuj. Nws yog qhov zoo- haum rau siab- nrawm, tsis tu ncua, ntev- lub sijhawm ntau lawm, muaj txiaj ntsig zoo tiv thaiv kev sib txhuam thiab lub siab tsis tu ncua- ntxias hnav, yog li ncua cov menyuam lub neej thiab txo qhov zaus ntawm kev tu lub tshuab.
Cr12 hlaumuaj 2.0%–2.3% carbon thiab 11.0%–13% chromium, ua tau ib tug hardness ntawm Greater los yog sib npaug rau 58 HRC tom qab kev kho cua sov. Nws cov ntsiab lus carbon siab imparts tshwj xeeb hardness, thaum lub chromium alloying caij ho txhim kho hardenability thiab hnav tsis kam. Qhov no ua rau nws tsim nyog rau kev sib sau ua haujlwm siab - lub zog ntawm cov ntawv hlau thiab muaj peev xwm tiv taus qhov siab - siab loads ntsib thaum yob txoj kev.
Cr12MOVyog ib qho khoom siv feem ntau siv rau siab -kawg yob txoj kev rollers; nws muaj 1.45% -1.7% carbon thiab 11.0% -12.5% chromium, nrog rau qhov sib ntxiv ntawm 0.4% - 0.6% molybdenum thiab 0.15% -0.3% vanadium, ua tiav hardness ntawm ntau dua los yog sib npaug rau 60 HRC tom qab kev kho cua sov. Cov menyuam yaus ua los ntawm cov khoom siv no muaj lub zog ruaj khov thiab ua haujlwm rau deformation, thaum tseem muab siab - kub, siab - siab, thiab corrosion kuj.
Hauv kev lag luam,SKD 11cov ntaub ntawv kev ua tau zoo yog piv rau Cr12MoV thiabD2steels, thaumD3cov khoom ua tau zoo ib yam li Cr12; cov no tuaj yeem xaiv los ua lwm txoj hauv kev raws li cov kev xav tau tshwj xeeb.
KINGREAL Roll Former ua raws li lub hauv paus ntsiab lus ntawm kev xaiv xaiv, sib txuam cov menyuam ua los ntawm cov khoom siv zoo rau txhua tus.yob txoj kev tshuabraws li cov ntsiab lus tseem ceeb xws li cov neeg siv khoom cov ntaub ntawv, kev tsim, kev siv ntau lawm, thiab kev ua haujlwm. Qhov no ua kom muaj kev ruaj ntseg ntawm cov khoom siv, ua kom lub tshuab ua haujlwm zoo tshaj plaws, thiab txo qhov ntev - cov nqi tu rau tus neeg siv khoom.
