Tsim cov khoom yas buckle-DFM cov ntsiab lus tseem ceeb

Lub buckle yog qhov yooj yim tshaj plaws, ceev tshaj plaws, tus nqi qis tshaj plaws thiab feem ntau tus phooj ywg ib puag ncig ntawm kev sib dhos ntawm cov khoom yas. Tsis tas yuav siv cov ntsia hlau ntsia hlau thaum lub buckle sib dhos. Cov txheej txheem sib dhos yog yooj yim, thiab tsuas yog ib qho yooj yim ntxig qhov ua tiav tuaj yeem ua tiav ob lossis sib dhos ntawm ntau qhov chaw.

Classification ntawm buckles

Muaj ntau txoj hauv kev los faib cov buckles. Raws li cov duab ntawm lub buckle, feem ntau siv buckles tuaj yeem muab faib ua ncaj caj npab buckles, L-shaped buckles, U-shaped buckles, thiab circumferential buckles. Piv nrog rau lub caj npab ncaj hom buckle, vim qhov nce ntawm qhov ntev, cov duab thiab U-shaped buckle muaj elasticity ntau dua.

Raws li seb lub buckle puas tuaj yeem raug tshem tawm, lub buckle tau muab faib ua cov buckle uas tsis tuaj yeem tshem tau thiab tsis tshem tau buckle.

Raws li seb qhov cross-section ntawm buckle hloov, lub buckle yog muab faib ua ib caj npab ncaj thiab tapered buckle.

Lub tapered buckle pib ua thinner los ntawm lub hauv paus ntawm lub buckle. Piv nrog rau lub caj npab ncaj, lub tapered buckle tuaj yeem txo qhov kev ntxhov siab ntawm lub buckle thiab cia cov buckles loj dua thaum lub thickness ntawm lub hauv paus ntawm lub buckle yog tib yam. Tus nqi ntawm deformation. Lwm daim ntawv thov ntawm tapered buckle yog tias thaum lub zog ntawm lub caj npab ncaj buckle tsis txaus, tapered buckle tuaj yeem tsim los ntawm kev ntxiv cov khoom ntawm nws cov hauv paus hniav kom muaj zog.

Kev ceev faj rau kev tsim buckle

Ua ntej tsim lub buckle, koj yuav tsum nkag siab cov ntsiab lus tseem ceeb hauv qab no:> Cov khoom siv ntawm cov khoom siv yas siv.> Tus naj npawb ntawm cov sij hawm yuav tsum tau sib sau ua ke thiab disassembled.> Cov kev ntxhov siab thiab lub zog uas lub buckle tuaj yeem tiv taus thaum lub sijhawm sib dhos.> Lub tshuab ua haujlwm siab ua haujlwm ntawm lub buckle tom qab sib dhos.

2.1 Dimensions ntawm buckle

Qhov loj ntawm lub buckle yuav tsum xyuas kom meej tias lub buckle muaj lub zog txaus thiab elasticity kom lub buckle yuav tsis tawg thiab ua tsis tiav thaum sib dhos lossis disassembly. Yog li ntawd, tsim nyog buckle loj tsim yog ib qho tseem ceeb heev.


Buckle thickness t=0.5 ~ 0.6T buckle cag fillet Rmin=0.5t buckle qhov siab H=5 ~ 10t buckle los ua ke txhuas lub kaum sab xis α=25 ° ~ 35 ° buckle disassembly lub kaum sab xis β: β≈ 35 ° yog siv rau kev sib dhos uas tsis tuaj yeem xav tau kev quab yuam sab nraud; β≈45° yog siv rau detachable sib dhos uas yuav tsum tau me me sab nraud quab yuam; β≈80 ° ~ 90 ° yog siv rau kev sib dhos uas tsis tuaj yeem tshem tawm uas yuav tsum muaj lub zog loj sab nraud; buckle Sab saum toj thickness Y≤t

Lub thickness thiab qhov siab ntawm lub buckle yog lub ntsiab tseem ceeb uas txiav txim siab lub zog thiab elasticity ntawm buckle. Yog tias lub thickness ntawm lub buckle yog nyias, lub zog tsis muaj zog, thiab lub buckle tsis tuaj yeem tiv taus lub zog sib dhos ntau dua; Yog hais tias lub thickness ntawm lub buckle yog tuab heev, lub buckle tsis muaj elasticity, thiab nws yuav tawg vim tsis txaus offset thaum lub sij hawm sib dhos txheej txheem. Nyob rau tib lub sijhawm, lub buckle sib haum rau Cov phab ntsa yas yog qhov ua rau shrinkage tsis xws luag.

Cov ntaub ntawv yas sib txawv muaj qhov sib txawv ntawm qhov sib txawv vim lawv qhov sib txawv elastic modulus thiab lwm yam tsis. Qhov yuav tsum tau buckle loj tuaj yeem xam los ntawm cov qauv sib xws. Tau kawg, txoj hauv kev zoo tshaj plaws yog txhawm rau txheeb xyuas seb qhov loj me ntawm lub buckle tsim raws li qhov xav tau ntawm kev quab yuam los ntawm kev txheeb xyuas qhov tseeb.

2.1 Ua kom cov fillet ntawm lub hauv paus ntawm lub buckle kom tsis txhob muaj kev ntxhov siab

Hom tsis ua hauj lwm feem ntau ntawm cov buckle yog vim qhov sib txuas ntawm lub hauv paus ntawm lub buckle thiab cov phab ntsa ntawm qhov, uas ua rau muaj kev ntxhov siab nyob rau hauv lub hauv paus ntawm lub buckle, kom nws tawg thaum lub sij hawm sib dhos los yog disassembly. Yog li ntawd, cov ces kaum ntse yuav tsum tau zam ntawm lub hauv paus ntawm lub buckle, thiab tsawg kawg yog ib nrab ntawm lub thickness ntawm lub buckle yuav tsum sib npaug.


2.3 Cov buckles yog sib npaug

Yog hais tias ob qhov chaw yog haum los ntawm snaps, lub snaps yuav tsum tau muab sib npaug zos nyob ib ncig ntawm qhov chaw kom tusyees ris lub load. Yog hais tias ib feem yog yooj yim deformation, xav txog qhov muab lub buckle nyob ze rau ntawm qhov chaw uas ib feem yuav deformation, xws li lub ces kaum ntawm ib feem.

Qhov sib nrug ntawm cov buckles yuav tsum tau txiav txim siab raws li qhov tseeb ntawm cov buckles.

2.4 Siv qhov chaw tso rau sab los pab kev sib dhos ntawm cov khoom thiab xyuas kom meej qhov tseeb ntawm qhov sib dhos

Yog tiasPlastic lub rooj zaum siv buckleyog kiag li haum los ntawm buckles, vim qhov tsis tshua muaj qhov tseeb ntawm cov buckles, qhov tseeb ntawm kev sib dhos ntawm cov khoom yog lav. Qhov no yog qhov tsis zoo ntawm lub buckle los ua ke. Nyob rau lub sijhawm no, los ntawm kev ntxiv cov ncej thiab qhov chaw ua haujlwm kom ntseeg tau tias qhov sib dhos loj ntawm cov khoom thiab txhim kho kev sib dhos kom raug.

Muaj ob qhov txiaj ntsig ntawm kev siv cov ntawv tso npe thiab tso qhov qhov. Ua ntej, nyob rau hauv cov txheej txheem los ua ke ntawm ob qhov chaw, lub positioning kem thiab positioning qhov ntawm qhov tsim nyog qhov siab sib cuag ntawm lub rooj sib txoos nta ntawm lub buckle (uas yog, qhov siab ntawm lub positioning kem ntawm cov yas yog siab tshaj qhov siab ntawm lub buckle). buckle), uas tuaj yeem yog Cov txheej txheem sib dhos ntawm cov khoom muab kev taw qhia thiab txhim kho kev sib dhos ua haujlwm. Nyob rau lub sijhawm no, lub luag haujlwm ntawm txoj haujlwm ntawm kab ntawv ua lub luag haujlwm coj; Thib ob, kev siv cov kab ntawv tso tawm tuaj yeem zam qhov kev puas tsuaj los ntawm kev sib dhos ntxhib.


2.5 Tus tsim buckle zam kom tsis txhob nce qhov nyuaj ntawm cov pwm

Kev tsim cov buckle tsis tsim nyog tuaj yeem yooj yim nce qhov nyuaj ntawm kev txhaj tshuaj pwm, thiab cov khoom yuav tsum muaj cov txheej txheem rub tawm sab nraud, uas ua rau tus nqi ntawm cov pwm nce ntxiv. Kev tsim cov buckle kom zoo tuaj yeem ua kom yooj yim rau cov qauv pwm. Qhib lub qhov ntawm lub hauv paus ntawm lub buckle tuaj yeem zam qhov rov qab buckling, thiab kev txhaj tshuaj pwm tsis tas yuav tsum muaj cov txheej txheem lateral-rub, uas yooj yim rau cov qauv pwm.


2.6 Tus tsim buckle yuav tsum xav txog qhov yooj yim ntawm kev hloov pwm

Tus tsim buckle feem ntau xav tau ntau yam kev hloov kho (xws li hloov qhov ntev, tuab, offset, thiab lwm yam.) kom ua tau raws li qhov yuav tsum tau ua ntawm cov khoom sib dhos. Yog li ntawd, qhov tsim loj ntawm lub buckle tuaj yeem me ntsis me ntsis es tsis txhob siv ib zaug Ua kom qhov loj ntawm lub buckle txaus los muab kev yooj yim rau kev hloov pwm tom ntej.
