Sheet Hlau dabtsi yog khoov Parameters Guide
Sheet Hlau dabtsi yog khoov
Hais txog cov txheej txheem ntawm kev hloov lub kaum sab xis ntawm cov ntawv hlau lossis phaj, xws li cov ntawv khoov rau hauv V-shaped, U-shape, thiab lwm yam. Feem ntau, muaj ob txoj hauv kev rau cov ntawv hlau dabtsi yog khoov: ib txoj kev yog tuag dabtsi yog khoov, uas yog siv. rau structurally complex, me me ntim, thiab loj-tsim daim ntawv hlau lug; lwm qhov yog dabtsi yog khoov tshuab dabtsi yog khoov, uas yog siv rau kev ua cov txheej txheem loj loj los yog qis ntim ntawv hlau cov qauv. Ob txoj kev khoov no muaj lawv tus kheej cov hauv paus ntsiab lus, yam ntxwv, thiab siv tau.
Tuag Bending:
Rau kev ua txhua xyoo ntau tshaj 5, 000 daim thiab qhov ntau thiab tsawg uas tsis loj (feem ntau 300X300), cov tuam txhab feem ntau xav txog kev tuag stamping rau kev ua.
Kauj Ruam Txheej Txheem
Rau qee cov ntawv hlau Z-zoo li cov kauj ruam khoov nrog qhov siab qis, cov neeg tsim khoom feem ntau siv cov tuag yooj yim ntawm stamping presses lossis hydraulic presses rau kev ua haujlwm. Rau cov khoom me me, lawv kuj tuaj yeem ua tiav ntawm lub tshuab dabtsi yog khoov nrog ntu sib txawv tuag, 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 nyob hauv (0-1.0)t. Yog tias qhov siab yog (1.
Qhov siab ntawm cov kauj ruam tuag no tuaj yeem hloov kho los ntawm kev ntxiv shims, yog li qhov siab H yog kho tau. Txawm li cas los xij, muaj qhov tsis zoo: qhov ntev L qhov ntev tsis yooj yim los xyuas kom meej, thiab qhov ntsug ntawm ntug ntsug tsis yooj yim los lav. Yog tias qhov siab H qhov loj me, nws yuav tsum xav txog kev khoov ntawm lub tshuab dabtsi yog khoov.
Bending machines tuaj nyob rau hauv ob hom: pa bending 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 rau cov khoom siv sib txuas lus feem ntau ua tiav ntawm CNC dabtsi yog khoov tshuab. Lub hauv paus ntsiab lus tseem ceeb yog siv lub tshuab dabtsi yog khoov rab riam (sab saum toj tuag) thiab V-groove (qis tuag) los khoov thiab tsim cov ntawv hlau.
Qhov zoo: Yooj yim rau clamp, raug qhov chaw, ua haujlwm ceev ceev.
Qhov tsis zoo: Tsis tshua muaj siab, tuaj yeem ua cov duab yooj yim, tsis tshua muaj txiaj ntsig.
Khoov Riam (Upper Die)
Cov ntaub ntawv ntawm rab riam yog qhia hauv daim duab hauv qab no. Thaum ua tiav, lawv tsuas yog xaiv raws li qhov xav tau ntawm lub workpiece. Cov neeg tsim khoom feem ntau muaj ntau yam kev khoov cov duab, tshwj xeeb tshaj yog cov uas muaj kev kawm tshwj xeeb, uas tau txiav txim ntau cov duab thiab cov lus qhia ntawm kev khoov riam los ua ntau yam kev khoov.
Cov tuag qis feem ntau siv V=6t (t yog cov khoom tuab) tuag.
Muaj ntau yam cuam tshuam rau kev ua haujlwm dabtsi yog khoov, feem ntau suav nrog lub vojvoog tuag sab sauv, cov khoom siv, cov khoom siv tuab, lub zog tuag qis, qis tuag qhov ncauj loj, thiab lwm yam. Kom ua tau raws li qhov xav tau ntawm cov khoom, thaum ua kom muaj kev nyab xeeb ntawm kev siv lub tshuab dabtsi yog khoov, manufacturers tau standardized lub dabtsi yog khoov riam tuag. Peb yuav tsum muaj kev nkag siab dav dav ntawm cov cuab yeej khoov uas twb muaj lawm tuag thaum lub sij hawm tsim cov txheej txheem. Saib daim duab hauv qab no, sab laug yog qhov tuag saum toj, thiab sab xis yog qhov tuag qis.
Basic Principles of Bending Processing Order:
(1) Khoov ntawm sab hauv tawm;
(2) Khoov ntawm me mus rau loj;
(3) Khoov cov duab tshwj xeeb ua ntej, tom qab ntawd cov duab dav dav;
(4) Cov txheej txheem yav dhau los yuav tsum tsis txhob cuam tshuam lossis cuam tshuam rau cov txheej txheem tom ntej tom qab tsim.
Khoov Radius
Thaum cov ntawv hlau yog khoov, yuav tsum muaj lub vojvoog khoov ntawm qhov khoov. Lub vojvoog dabtsi yog khoov yuav tsum tsis txhob loj lossis me dhau thiab yuav tsum tau xaiv kom tsim nyog. Lub vojvoog dabtsi yog khoov uas me dhau tuaj yeem ua rau tawg ntawm qhov khoov tau yooj yim, thiab lub vojvoog dabtsi yog khoov uas loj dhau ua rau qhov khoov yuav rov ua dua.
Rau cov pa roj carbon tsawg zoo tib yam, anti-xeb txhuas daim hlau, tooj liab daim hlau, tooj liab daim hlau, thiab lwm yam., ib tug puab fillet ntawm 0.2 yog tsis muaj teeb meem, tab sis rau ib co high-carbon steel, nyuaj aluminium, super -hard aluminium, qhov khoov fillet no yuav ua rau khoov pob txha los yog sab nrauv fillet tawg.
Khoov Springback
Lub kaum sab xis Springback Δ =ba
Nyob rau hauv cov mis, b-lub kaum ntse ntse ntawm lub workpiece tom qab springback;
a-lub kaum sab xis ntawm qhov tuag.
Yam tseem ceeb cuam tshuam rau springback thiab ntsuas los txo qhov springback
(1) Cov khoom siv kho tshuab ntawm cov khoom siv: Qhov loj ntawm lub kaum sab xis 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, kom txo tau springback, cov ntaub ntawv yuav tsum tau. xaiv kom tsawg-carbon steel ntau npaum li sai tau, thiab high-carbon steel thiab stainless hlau yuav tsum tsis txhob xaiv.
(2) Tus txheeb ze dabtsi yog khoov vojvoog r / t: qhov loj dua, qhov me me ntawm qhov deformation, thiab qhov loj dua lub caij nplooj ntoos hlav Δ . Qhov no yog ib lub tswv yim tseem ceeb heev. Lub fillet ntawm daim ntawv hlau dabtsi yog khoov yuav tsum me me li sai tau nyob rau hauv cov kev txwv ntawm cov khoom siv los txhim kho precision. Kev saib xyuas tshwj xeeb yuav tsum tau them nyiaj kom tsis txhob tsim cov radii loj, raws li qhia hauv daim duab hauv qab no. Xws li radii loj ua rau muaj teeb meem ntau dua rau kev tsim khoom thiab kev tswj kom zoo.
