sheet hlau dabtsi yog khoov
Nws yog hais txog kev ua ntawm kev hloov lub kaum sab xis ntawm lub phaj lossis phaj. Xws li khoov daim ntawv rau hauv V shape, U shape, thiab lwm yam. Feem ntau, muaj ob txoj hauv kev rau cov ntawv hlau dabtsi yog khoov: ib txoj hauv kev yog pwm dabtsi yog khoov, uas yog siv rau cov ntawv hlau nrog cov qauv nyuaj, ntim me me, thiab kev ua haujlwm loj; lwm yam yog dabtsi yog khoov tshuab dabtsi yog khoov, uas yog siv Nws yog tsim rau ua cov ntaub ntawv hlau lug nrog cov qauv loj loj loj los yog nrog cov zis tsawg. Ob txoj kev khoov no muaj lawv tus kheej lub hauv paus ntsiab lus, yam ntxwv thiab siv tau.
Tuag dabtsi yog khoov:
Rau cov khoom siv uas muaj qhov ntim txhua xyoo ntau dua 5, 000 daim thiab qhov loj me tsis loj (300X300 feem ntau), cov tuam txhab ua lag luam feem ntau xav txog kev qhib cov pwm pwm rau kev ua haujlwm.
Feem ntau siv khoov tuag
Feem ntau siv khoov tuag, raws li qhia hauv daim duab hauv qab no. Txhawm rau kom lub neej ntev ntawm cov pwm, cov kab sib npaug yuav tsum tau siv ntau li ntau tau thaum tsim cov khoom.
duab
Yog tias qhov siab flange me dhau lawm, nws tsis tsim nyog rau kev tsim txawm tias siv cov bending tuag. Feem ntau, flange qhov siab L Ntau dua lossis sib npaug rau 3t (xws li phab ntsa tuab).
Txoj kev ua cov kauj ruam
Rau qee qhov siab qis ntawm cov ntawv hlau Z-zoo li cov kauj ruam dabtsi yog khoov, cov tuam txhab ua haujlwm feem ntau siv cov pwm yooj yim los ua cov txheej txheem ntawm cov punch presses lossis hydraulic presses. Yog tias qhov loj me me tsis loj, lawv tuaj yeem ua tiav ntawm cov tshuab khoov nrog segmental txawv pwm, raws li qhia hauv daim duab hauv qab no. Txawm li cas los xij, nws qhov siab H yuav tsum tsis txhob siab dhau, feem ntau nws yuav tsum yog (0-1.0) t, yog tias qhov siab yog (1.0-4.0) t , daim ntawv pwm nrog loading thiab unloading qauv yuav tsum tau txiav txim siab raws li qhov tseeb qhov teeb meem.
Qhov siab ntawm cov pwm pwm no tuaj yeem hloov kho los ntawm kev ntxiv shims, yog li qhov siab H tuaj yeem hloov kho arbitrarily, tab sis kuj muaj qhov tsis zoo, uas yog, qhov ntev L tsis yooj yim los lav, thiab qhov ntsug ntawm sab ntsug tsis yog. yooj yim lav. Yog tias qhov siab H qhov siab loj heev, nws yuav tsum xav txog kev khoov ntawm lub tshuab dabtsi yog khoov.
duab
Lub tshuab dabtsi yog khoov tau muab faib ua ob hom: zoo tib yam dabtsi yog khoov tshuab thiab CNC dabtsi yog khoov tshuab. Vim tias qhov kev xav tau siab thiab cov duab tsis sib xws, cov ntawv hlau dabtsi yog khoov ntawm cov khoom siv sib txuas lus feem ntau yog khoov nrog lub tshuab CNC dabtsi yog khoov. Lub hauv paus ntsiab lus tseem ceeb yog siv rab riam dabtsi yog khoov (sab saum toj tuag) thiab V-shaped zawj (qis tuag) ntawm lub tshuab dabtsi yog khoov Tuag), dabtsi yog khoov thiab tsim cov ntawv hlau.
Qhov zoo: yooj yim clamping, raug qhov chaw, ceev ceev ceev;
Disadvantages: Lub siab me me, tsuas yog yooj yim txoj kev tuaj yeem ua tiav, thiab kev ua haujlwm tsawg.
Cov txheej txheem ntawm kev tsim
Lub hauv paus ntsiab lus ntawm kev tsim muaj nyob rau hauv daim duab hauv qab no:

Khoov riam (upper tuag)
Daim ntawv ntawm rab riam yog qhia hauv daim duab hauv qab no. Thaum lub sij hawm ua, nws yog tsuas yog xaiv raws li cov duab ntawm lub workpiece. Feem ntau, cov tuam txhab lag luam muaj ntau cov duab ntawm kev khoov riam, tshwj xeeb tshaj yog rau cov tuam txhab uas muaj kev paub tshwj xeeb. Txhawm rau ua cov txheej txheem ntau yam kev khoov, Customize dabtsi yog khoov riam ntawm ntau daim duab thiab specifications.
Cov pwm qis feem ntau siv V=6t (t yog cov khoom tuab) pwm.
Muaj ntau yam uas cuam tshuam rau cov txheej txheem dabtsi yog khoov, feem ntau suav nrog lub vojvoog arc ntawm lub siab tuag, cov khoom siv, qhov tuab ntawm cov khoom, lub zog ntawm qhov tuag qis, thiab qhov loj ntawm qhov tuag qhib ntawm qhov tuag qis. Yuav kom ua tau raws li qhov xav tau ntawm cov khoom thiab ua kom muaj kev nyab xeeb ntawm lub tshuab dabtsi yog khoov, cov chaw tsim khoom tau serialized cov dabtsi yog khoov tuag. Peb yuav tsum muaj kev nkag siab dav dav ntawm qhov uas twb muaj lawm khoov tuag thaum lub sij hawm tsim qauv txheej txheem. Raws li pom hauv daim duab hauv qab no, cov pwm sab saud yog nyob rau sab laug thiab cov pwm qis yog nyob rau sab xis.

Lub hauv paus ntsiab lus ntawm bending processing sequence:
(1) Khoov ntawm sab hauv mus rau sab nraud;
(2) Khoov ntawm me mus rau loj;
(3) Khoov cov duab tshwj xeeb ua ntej, thiab tom qab ntawd khoov cov duab dav dav;
(4) Tom qab tsim cov txheej txheem dhau los, nws yuav tsis cuam tshuam lossis cuam tshuam rau cov txheej txheem tom ntej.
Daim ntawv khoov tam sim no feem ntau yog raws li qhia hauv daim duab hauv qab no:

2 khoov vojvoog
Thaum dabtsi yog khoov daim ntawv hlau, yuav tsum muaj ib tug dabtsi yog khoov vojvoog ntawm lub dabtsi yog khoov taw tes, thiab cov dabtsi yog khoov vojvoog yuav tsum tsis txhob loj heev los yog me me, thiab yuav tsum tau xaiv kom tsim nyog. Yog hais tias lub vojvoog dabtsi yog khoov me me dhau, nws yooj yim ua rau tawg ntawm qhov khoov taw tes, thiab yog tias lub vojvoog dabtsi yog khoov loj heev, qhov khoov yog yooj yim rau rebound.
Qhov zoo tshaj plaws dabtsi yog khoov vojvoog ( puab bending vojvoog) ntawm ntau yam ntaub ntawv thiab txawv thicknesses yog qhia nyob rau hauv cov lus hauv qab no

Cov yam ntxwv cuam tshuam rau Springback thiab ntsuas kom txo Springback
(1) Lub zog ntawm cov khoom siv Lub kaum sab xis ntawm lub springback yog proportional rau qhov taw tes tawm ntawm cov khoom thiab inversely proportional rau elastic modulus E. Rau daim ntawv hlau qhov chaw nrog high precision yuav tsum, thiaj li yuav txo tau springback, cov khoom yuav tsum tau raws li low-carbon steel li sai tau, es tsis txhob high-carbon steel thiab stainless hlau.
(2) Qhov loj dua tus txheeb ze khoov vojvoog r / t, qhov me me ntawm qhov deformation thiab qhov loj dua lub kaum sab xis Δ . Qhov no yog ib lub tswv yim tseem ceeb heev. Lub kaum sab xis ntawm cov ntawv hlau dabtsi yog khoov yuav tsum me me li sai tau thaum cov khoom siv tso cai, uas yog qhov tsim nyog rau kev txhim kho qhov tseeb. Tshwj xeeb, nws yuav tsum tau muab sau tseg tias tus tsim ntawm arcs loj yuav tsum zam kom ntau li ntau tau, raws li qhia nyob rau hauv daim duab hauv qab no, xws li arcs loj yog nyuaj rau ntau lawm thiab kev tswj kom zoo:
