Core Principles thiab Logic
Cov txheej txheem no leverages cov neeg kho tshuab siab generated los ntawm rotating rollers ua ke nrog cov yas deformation yam ntxwv ntawm cov khoom kom maj mam muab cov khoom mus rau hauv ib tug preset daim ntawv los ntawm ib tug series ntawm dov kis. Tshwj xeeb, cov txheej txheem tuaj yeem tawg mus rau hauv cov theem hauv qab no:
Force Transmission: Lub cev muaj zog tsav cov chais kom tig; Raws li cov khoom nkag mus rau qhov sib txawv ntawm cov chais, nws raug rau ob qho tib si radial compressive rog thiab frictional rog.
Yas Deformation: Nyob rau hauv lub siab, cov khoom ntawm cov kev nyuaj siab tshaj nws cov yield zog, ua rau ib tug irreversible hloov nyob rau hauv nws cov duab.
Nruam txoj kev: Cov khoom pub rau pem hauv ntej tsis tu ncua raws li cov rollers tig; los ntawm kev ua ntu zus los ntawm ntau pawg ntawm cov menyuam yaus, nws thaum kawg ua tiav qhov kev xav tau hla -sectional profile.
Cov ntsiab lus tseem ceeb ua haujlwm
Roller System: Lub Ntsiab ntawm Cov Duab thiab Kev Tswj Siab
Roller Design:
Qhov chaw ntawm cov menyuam yaus yog tsim los nrog cov convex thiab concave grooves kom phim lub hom phiaj cross-sectional profile (piv txwv li, thaum tsim C- channel steel, cov menyuam contours yuav tsum sib haum rau qhov xav tau channel profile). Multiple sets of rollers are arranged according to the principle of "progressive forming"-earlier rollers perform the initial bending, while subsequent rollers gradually refine the dimensions and angles to achieve the final shape.
Kev kho siab:
Hydraulic lossis mechanical mechanisms yog ua haujlwm los kho qhov sib txawv ntawm cov menyuam, yog li tswj qhov loj ntawm qhov kev thov siab. Kev tsis txaus siab ua rau ua tsis tiav, qhov siab dhau tuaj yeem ua rau cov khoom tawg lossis ua kom cov menyuam hnav nrawm dua.
Khoom noj khoom haus thiab kis tau tus mob
Txoj kev pub mis:
Cov khoom siv (piv txwv li, steel strips, aluminium ntawv) yog pub rau hauv cov menyuam qhov sib txawv ntawm qhov ceev tsis tu ncua los ntawm cov khoom siv pub mis (xws li cov menyuam conveyor lossis siv conveyor). Kev pub noj ceev yuav tsum tau synchronized nrog kev sib hloov ceev ntawm cov chais (feem ntau yog li ntawm 0.5 mus rau 10 meters ib feeb, hloov kho raws li cov khoom tuab thiab tsim cov complexity).
Fais fab kis:
Lub cev muaj zog tsav cov chais los ntawm cov khoom xws li kev ceev reducers thiab gearboxes, kom ntseeg tau qhov kev sib hloov ceev (nrog rau kev ua siab ntev tsawg dua lossis sib npaug li 1%) los tiv thaiv qhov sib txawv ntawm qhov sib txawv ntawm cov khoom tsim los ntawm kev hloov pauv ceev.
Kev taw qhia thiab qhov chaw Devices Inlet Guiding:
Flared phau ntawv qhia daim hlau los yog adjustable qhia rollers yog siv nyob rau hauv lub inlet los xyuas kom meej cov khoom nkag mus rau hauv nruab nrab ntawm cov menyuam sib txawv nrog precision, yog li tiv thaiv skewing los yog warping.
Ncej -Forming Positioning:
Kev them nyiaj yug rollers los yog cov khoom siv ncaj nraim tau nruab rau ntawm qhov kawg ntawm qhov tso tawm kom tsis txhob muaj qhov profile los ntawm kev deformation los ntawm kev ntxhov siab tso tawm.
Kauj Ruam -los ntawm -Txoj Kev Ntsuam Xyuas Cov Txheej Txheem Tsim
Siv C-channel steel tsim ua piv txwv, cov haujlwm ua haujlwm tuaj yeem muab faib ua plaub theem:
Thawj theem pub mis
Cov ntaub ntawv tiaj tus yog pub los ntawm kev pub mis rau hauv thawj txheej ntawm cov menyuam, uas ua rau thawj zaug nias los tsim lub pre-bending lub kaum sab xis rau sab flanges (piv txwv li, 15-30 degrees).
Progressive Forming Theem
Cov khoom siv dhau los ntawm cov txheej txheem 2 txog 8 ntawm cov yob (nyob ntawm qhov xav tau qhov tseeb); Txhua txheej txheej txheej txheej txheej txheej nce lub flange lub kaum sab xis (piv txwv li, los ntawm 10-15 degrees ib zaug) thaum tib lub sijhawm tswj qhov siab thiab flatness ntawm lub vev xaib (qhov nruab nrab ntsug ntu).
Tiav thiab Sizing Theem
Cov txheej txheem kawg ntawm cov menyuam siv cov xovxwm precision rau tus ntoo khaub lig- ntu, kho qhov yuam kev angular (kom tsawg dua lossis sib npaug li 1 degree), kom ntseeg tau qhov perpendicularity ntawm flanges txheeb ze rau lub vev xaib, thiab ib txhij tshem tawm txhua feeb ntawm wrinkles.
Txiav thiab Tshem Tawm Theem
Cov tsim ntev profile yog txiav mus rau qhov ntev ntev los ntawm ya shear lossis sawing ntaus ntawv thiab tom qab ntawd xa tawm ntawm txoj siv conveyor, yog li ua tiav cov khoom tiav.
Daim ntawv thov txuas ntxiv ntawm cov ntsiab cai: CNC Roll Forming Technology
Niaj hnub nimno yob txoj kev tshuab integrate Computer Numerical Control (CNC) systems los txhim kho cov precision ntawm txoj kev tsim los ntawm cov hauv qab no txoj kev:
Tiag -lub sij hawm Parameter Kho: Sensors tsis tu ncua saib cov khoom tuab thiab kub nyob rau hauv lub sij hawm ntawm lub sij hawm, tso cai rau lub CNC system txiav zoo zoo - kho cov menyuam qhov sib nrug thiab siab.
Multi-axis Coordinated Control: Rau txoj kev hla- ntu (xws li qhov sib txawv -section profiles), servo motors tsav ntau pawg ntawm cov menyuam los ua haujlwm hauv kev sib koom ua ke, yog li ua tiav peb- qhov sib txawv.
Virtual Simulation thiab Pre-visualization: CAD/CAM software yog siv los simulate tag nrho cov txheej txheem tsim, tso cai rau ua ntej -kev ua kom zoo ntawm cov menyuam cov kev npaj thiab cov txheej txheem, uas yuav pab txo qis cov khoom pov tseg uas cuam tshuam nrog kev sim lub cev.
