1. Cov ntsiab lus ua cov tshuab folding
1. L quav
Raws li lub kaum sab xis, nws muab faib ua 90˚ quav thiab tsis yog 90˚ quav.
Raws li kev ua tiav, nws muab faib ua kev ua tiav dav dav (L> V / 2) thiab kev ua tiav tshwj xeeb (L
>Cov pwm raug xaiv raws li cov khoom siv, qhov tuab ntawm lub phaj, thiab lub kaum sab xis.
>Lub Ntsiab Cai ntawm Kev Cia Siab
①Raws li lub hauv paus ntsiab lus ntawm ob qho kev tso chaw tom qab kho, thiab kev tso chaw raws li cov duab ntawm cov khoom ua haujlwm.
②Ua tib zoo saib xyuas qhov deflection thaum txoj cai rov qab raug tso rau, thiab nws yuav tsum nyob rau tib txoj kab nruab nrab nrog qhov ntev ntawm qhov workpiece.
③Yog tias muaj cov khoov me me, qhov chaw rov qab zoo dua.
④Zoo dua yog teem txoj cai rov qab thiab qis dua hauv nruab nrab. (Thaum nyo rov qab, cov cai tsis yooj yim rau qaij)
⑤Zoo dua nyob ze rau txoj cai rov qab.
⑥Sab ntev zoo dua.
⑦Siv cov jigs los pab qhov chaw (qhov chaw tsis sib xws ntawm hypotenuse).
>Cov kev ceev faj
①Ua tib zoo mloog rau txoj kev tso chaw thaum lub sijhawm ua haujlwm thiab hom kev txav mus los ntawm kev tswj hwm tom qab hauv ntau txoj kev ua haujlwm tso chaw.
②Thaum lub pwm raug ntsia, nws yuav tsum tau khoov rov qab kom tiv thaiv tau qhov workpiece los ntawm kev deforming thaum nws khoov.
③Thaum lub workpiece loj raug khoov sab hauv, vim yog lub workpiece loj dua thiab thaj chaw khoov me dua, nws nyuaj rau lub cuab yeej thiab thaj chaw khoov sib tshooj, ua rau qhov chaw ntawm lub workpiece nyuaj lossis ua rau lub workpiece khoov puas tsuaj. Yuav kom tsis txhob muaj qhov xwm txheej saum toj no, koj tuaj yeem ntxiv qhov chaw nyob rau hauv qhov kev coj ua ntev ntawm kev ua, kom cov txheej txheem raug tso rau hauv ob qho kev coj ua, uas ua rau qhov chaw ua haujlwm yooj yim, thiab txhim kho kev nyab xeeb ntawm kev ua haujlwm, zam kev puas tsuaj ntawm lub workpiece, thiab txhim kho kev ua haujlwm zoo.
2. N quav
N-folds xav tau cov txheej txheem ua tiav sib txawv raws li cov duab sib txawv. Thaum khoov, qhov loj me sab hauv ntawm cov khoom yuav tsum loj dua 4MM, thiab qhov loj ntawm X loj yog txwv los ntawm cov duab ntawm pwm. Yog tias qhov loj me sab hauv ntawm cov khoom tsawg dua 4MM, siv txoj kev tshwj xeeb rau kev ua tiav.
>Xaiv cov pwm raws li cov khoom tuab, qhov loj me, cov khoom siv thiab lub kaum sab xis.
>Lub Ntsiab Cai ntawm Kev Cia Siab
①Xyuas kom meej tias qhov workpiece tsis cuam tshuam rau pwm
②Xyuas kom tseeb tias lub kaum sab xis ntawm qhov chaw tsawg dua 90 degrees.
③Nws yog qhov zoo tshaj plaws los siv ob txoj cai tom qab txiav txim siab, tshwj tsis yog rau cov xwm txheej tshwj xeeb.
>Cov kev ceev faj
①Tom qab khoov L-folding, lub kaum sab xis yuav tsum nyob ntawm 90 degrees lossis tsawg dua 90 degrees kom yooj yim rau kev ua thiab kev tso chaw.
②Thaum lub sijhawm ua cov txheej txheem thib ob, qhov chaw tso yuav tsum tau nyob hauv nruab nrab ntawm qhov chaw ua tiav.
3. Z quav
Nws tseem hu ua qhov sib txawv ntawm cov kauj ruam, uas yog, ib qho zoo thiab lwm qhov rov qab khoov. Raws li lub kaum sab xis, qhov sib txawv ntawm hypotenuse thiab ntug ncaj yog faib.
Qhov tsawg kawg nkaus ntawm kev ua cov khoom khoov yog txwv los ntawm cov pwm ua, thiab qhov siab tshaj plaws ntawm kev ua yog txiav txim siab los ntawm cov duab ntawm lub tshuab ua. Nyob rau hauv cov xwm txheej ib txwm muaj, thaum qhov loj me sab hauv ntawm cov khoom Z-folded tsawg dua 3.5T, kev ua cov txheej txheem sib txawv segmental siv. Thaum nws loj dua 3.5T, txoj kev ua cov txheej txheem ib txwm raug saws.
>Lub Ntsiab Cai ntawm Kev Cia Siab
①Kev tso chaw yooj yim thiab kev ruaj khov zoo.
②Qhov chaw dav dav yog tib yam li L quav.
③Qhov kev tso chaw thib ob yuav tsum tau ua kom cov khoom ua tiav thiab cov pwm qis dua sib npaug.
>Cov kev ceev faj
①Lub kaum sab xis ua haujlwm ntawm L-fold yuav tsum nyob rau hauv qhov chaw, feem ntau yog 89.5—90 degrees.
②Them sai sai rau qhov deformation ntawm lub workpiece thaum rub rov qab tom qab txoj cai.
③Qhov kev txiav txim ntawm kev ua yuav tsum yog qhov tseeb.
④Rau kev ua tshwj xeeb, cov txheej txheem hauv qab no tuaj yeem siv rau kev ua:
——- Txoj kev sib cais kab nruab nrab (kev ua eccentric)
——- Kev ua V me me (yuav tsum tau ua kom cov coefficient ntawm kev khoov nce ntxiv)
——- Yooj yim pwm tsim
——- Rov kho dua qhov tuag qis dua
4. Rov qab quav thiab tiaj tus
Kev khoov rov qab kuj tseem hu ua ntug tuag.
Cov kauj ruam ua cov ntug tuag:
① Ua ntej, khoov thiab ntxig rau li 35 degrees.
② Siv lub pwm flattening los flattening kom txog thaum nws tiaj tus thiab nruj.
>Kev xaiv hom
Raws li 5-6 npaug ntawm cov khoom siv tuab, xaiv qhov dav V-groove ntawm cov pwm qis dua nrog qhov tob ntawm 30 degrees, thiab xaiv cov pwm sab saud raws li cov xwm txheej tshwj xeeb ntawm cov ntug tuag machining.
>Cov kev ceev faj
Ua tib zoo saib seb ob sab ntawm sab tuag puas sib luag. Thaum qhov loj ntawm sab tuag ntev dua, sab uas tiaj tiaj yuav muab tais ua ntej thiab tom qab ntawd tiaj tiaj. Yog xav kom cov npoo tuag luv dua, siv cov ntaub mos mos los ua.
5. Kho vajtse nias
Siv lub tshuab folding los nias thiab sib txuas cov khoom siv, feem ntau siv lub qhov, lub khoom siv thiab lwm yam kev ua pwm pab.
Nyob rau hauv ib txwm muaj cov xwm txheej muaj: compression nuts, compression studs, compression screws thiab lwm yam khoom siv.
>Cov kev ceev faj
①Thaum cov duab ntawm cov workpiece xav tau kom tsis txhob ua tiav, qhov chaw yuav tsum tau zam.
②Tom qab ua tiav lawm, xyuas lub zog torque, seb lub zog thawb mus txog tus qauv, thiab seb cov khoom siv kho vajtse thiab cov khoom ua haujlwm puas sib npaug thiab nruj.
③Tom qab khoov, thaum nias ib sab ntawm lub cuab yeej tshuab, them sai sai rau qhov chaw ua haujlwm thiab qhov sib luag ntawm cov pwm.
④Yog tias nws yog qhov bulge, thov xyuam xim tias yuav tsum tsis muaj qhov tawg ntawm qhov bulge, thiab qhov bulge yuav tsum tsis txhob siab dua qhov chaw ntawm qhov workpiece.
6. Kev tsim pwm yooj yim
Cov ntsiab lus ua tiav dav dav ntawm kev tsim pwm yooj yim suav nrog: qhov sib txawv me me, nuv, kos choj, kos hnab, nias shrapnel thiab qee cov duab tsis xwm yeem.
Lub hauv paus ntsiab lus tsim ntawm pwm yooj yim yog hais txog "Laser txiav pwm yooj yim tsim txoj cai"
Cov pwm yooj yim feem ntau yog muab tso rau lossis muab tso rau tus kheej tom qab siv.
Qhov tseem ceeb tshaj plaws rau kev ua cov ntsiab lus saum toj no nrog kev ua pwm yooj yim yog tias nws cov haujlwm thiab kev sib dhos tsis cuam tshuam, thiab qhov tsos yog qhov qub.
2. Cov teeb meem tshwm sim hauv kev ua cov tshuab folding thiab cov kev daws teeb meem
1. Qhov tshwm sim ntawm kev plam thaum lub sijhawm ua tiav
