1.Dab tsi yog qhov tseem ceeb cuam tshuam rau kev rov qab los?
Material Properties (Qhov tseem ceeb tshaj)
Yield Strength: Qhov no yog qhov tseem ceeb tshaj plaws. Qhov siab dua qhov tawm los lub zog, qhov ntau dua lub springback.
Galvanized Coil Qib: Cov qib sib txawv ntawm cov substrate (xws li DX51D, DX52D, DC01, SGCC, thiab lwm yam) muaj qhov sib txawv ntawm qhov muaj zog. Piv txwv li, siab -lub zog steels xws li SGC400/440/550 siv rau cov khoom vaj tse muaj lub caij nplooj ntoos hlav ntau dua li DC01 (SPCC).
Zinc Txheej Hom thiab Thickness: Kub-dip galvanized (GI) thiab electro-galvanized (EG) substrates yog txawv. Feem ntau, kub-dip galvanized substrates yog softer, uas ua rau lub springback kuj tsawg. Lub zinc txheej nws tus kheej yog mos heev thiab muaj kev cuam tshuam me ntsis rau lub caij nplooj ntoos hlav, tab sis cov zinc txheej tuab tuaj yeem tsim cov kab nrib pleb me me ntawm qhov khoov taw tes, cuam tshuam tsis ncaj rau lub caij nplooj ntoos hlav.
Khoom Thickness (T)
Lub thicker daim ntawv, qhov me me lub springback. Qhov no yog vim hais tias thaum ib daim ntawv tuab yog khoov, qhov compression thiab tensile deformation cheeb tsam ntawm ob sab ntawm lub nruab nrab txheej yog loj, uas ua rau ntau tiav yas deformation thiab ib tug me me feem ntawm elastic rov qab.
2.Yuav ua li cas koj kwv yees rov qab raws li cov cai ntawm tus ntiv tes xoo thiab cov nqi siv?
Raws li cov xwm txheej feem ntau (xws li qis- carbon steel galvanized ntawv DC01 / SPCC nrog lub thickness T=1.0-2.0mm, lub vojvoog dabtsi yog khoov R=0.5T ~ 1T, siv tus qauv V-groove), thaum khoov ntawm 90 degrees, lub springback lub kaum sab xis yog kwv yees li ntawm 1℃thiab 3 degree.
Txawm li cas los xij, rau siab - lub zog steel, tus nqi no tuaj yeem ncav cuag 5℃~ 10℃lossis ntau dua.
3.Yuav ua li cas kwv yees springback thaum sim molding thiab them nyiaj?
Qhov no yog tus txheej txheem ntau lawm. Tus txheej txheem engineer ua ntej teeb tsa qhov kev pab cuam khoov raws li kev paub dhau los thiab khoov tus qauv.
Tom qab ntawd, lawv ntsuas lub kaum ntse ntse uas siv lub kaum sab xis ntsuas thiab suav lub caij nplooj ntoo hlav (piv txwv li, yog lub hom phiaj yog 90℃thiab lub kaum ntse ntse yog 92 degree, lub springback yog 2 degree).
Tom qab ntawd, lawv muab tus nqi them rau hauv CNC dabtsi yog khoov tshuab, piv txwv li, xav kom lub tshuab khoov rau 88℃los them rau 2℃springback, yog li tau txais 90℃ib feem.
4.Yuav ua li cas txo rebound?
Tsim Phase: Siv qhov tsawg tshaj plaws ntawm qhov khoov lub vojvoog, nyob rau hauv cov qauv txwv.
Kev xaiv cov khoom siv: Ua ntej cov ntaub ntawv uas tsis tshua muaj zog (piv txwv li, DC01 / SPCC es tsis txhob SGC440) thaum ua tau raws li qhov yuav tsum tau muaj zog.
Bending txheej txheem:
Siv lub me me tuag V-groove dav.
Siv txoj kev kho (precision pressing): Thaum kawg ntawm qhov khoov stroke, siv lub siab siab heev rau lub ntsis ntawm lub kaum sab xis ntawm qhov khoov nrog lub me me compression, ua kom tiav cov yas deformation ntawm cov khoom nyob rau hauv cheeb tsam ntawd, txo cov springback. Qhov no yuav tsum tau muaj zog txaus los ntawm lub tshuab dabtsi yog khoov.
Kho Bending Ceev: Qee zaum, qis- nrawm nrawm yog qhov zoo rau cov khoom siv yas deformation txaus.
5.Yuav ua li cas kuv yuav siv ib tug dabtsi yog khoov lub rooj los yog software?
Cov kws tshaj lij CAD/CAM software (xws li SolidWorks thiab Pro/E's sheet hlau module) suav nrog ua- hauv cov lus khoov raws li cov khoom siv thiab cov tuab, uas twb tau them rau springback.
Qee lub tshuab CNC bending tshuab muaj kev tswj hwm kev hloov pauv uas tuaj yeem kho qhov siab ntawm lub sijhawm tiag tiag los tswj lub caij nplooj ntoo hlav.
