Countermeasures ntawm cov khoom tig thiab distortion thaum lub sijhawm stamping

Cov khoom siv tig thiab distortion yog cov teeb meem uas tshwm sim hauv lub sijhawm, uas tuaj yeem cuam tshuam qhov zoo thiab qhov tseeb ntawm cov khoom kawg. Cov teeb meem no feem ntau tshwm sim los ntawm kev sib xyaw ntawm cov yam ntxwv ntawm lub zog stamping, pwm tsim, thiab kev sib cuam tshuam ntawm cov punch thiab cov khoom siv. Nkag siab cov hauv paus ua rau thiab siv cov hauv paus tseem ceeb yog qhov tseem ceeb rau kev ua kom muaj kev ua haujlwm siab ntau thiab ua kom cov khoom siv stamp.

Thaum lub sij hawm cov txheej txheem stamping, lub zog xuas nrig ntaus ua si lub luag haujlwm tseem ceeb hauv kev ua rau cov khoom xa thiab hloov pauv. Thaum ib qho punch nkag mus rau cov khoom siv, lub zog siv tuaj yeem ua rau muaj kev faib tawm tsis ncaj ncees. Qhov no yog feem ntau vim muaj qhov muaj qhov sib txawv ntawm cov khoom sib txawv, uas ua rau cov khoom siv tau nce ntawm ib sab ntawm tus tuag thiab compressed ntawm ib sab punch. Qhov no tsis xwm txheej kev ntxhov siab ua rau cov khoom kom tig thiab twist, ua rau deformation nyob rau hauv lub stamped. Qhov ntau thiab kev coj ntawm punching quab yuam ncaj qha cuam tshuam ntawm cov khoom distortion, ua rau nws lub ntsiab lus tseem ceeb los tswj hauv cov txheej txheem stamping.

Ib txoj hauv kev zoo los txo cov khoom siv hloov thiab ntxeev yog los ntawm kev tsim nyog pwm tsim. Cov txheej txheem ntawm kev ua haujlwm tsis yog ib qho tseem ceeb tshwj xeeb, tshwj xeeb tshaj yog thaum yuav nrog nrog cov ntu me me. Los ntawm txoj kev npaj ua ntu zus, qhov cuam tshuam ntawm cov punching quab yuam ntawm kev ua luam ntawm cov khoom siv tau tuaj yeem txo qis. Piv txwv li, pib nrog daim pam thiab xuas nrig ntaus cov chaw loj dua ua ntej yuav mus rau thaj chaw me me pab faib cov rog ntxiv hla cov khoom. Cov qauv no txo ​​qis kev ntxhov siab hauv cheeb tsam uas feem ntau ua rau tig thiab sib ntswg ntawm cov khoom sib tw. Tsis tas li ntawd, kev xaiv cov pwm tsim kom ntseeg tau tias cov khoom ntws tau zoo thaum lub sijhawm stamping, ntxiv txo qhov ua kom tsis sib xws.

Lwm qhov kev daws teeb meem tshiab cuam tshuam nrog cov qauv uas tsis yog tsim qauv qauv tsim qauv. Los ntawm kev sib txuam ua ke cov khoom siv uas tsis haum rau ntawm lub phaj ntim, lub phaj tuaj yeem nias cov khoom khov kho, tiv thaiv nws los ntawm kev tig thiab sib ntswg thaum lub sij hawm punching. Cov qauv siv no tshwj xeeb tshaj yog ua tau zoo rau kev daws teeb meem ntsig txog kev hnav mus ntev thiab kua muag. Piv txwv li, txoj kev sib sau yuam kev ntawm cov pwm tuaj yeem siv cov khoom siv tsis muaj lub phaj nrog cov qauv thaiv. Qhov no tsis tsuas yog muab kev txhawb nqa ntxiv rau cov khoom siv tab sis kuj tseem yuav daws cov teeb meem ntawm kev hnav ntawm cov khoom ntim ntawm cov haujlwm uas yuav rov ua haujlwm. Cov txheej txheem txhim kho cov qauv no ua kom pom tseeb tias cov pwm khaws nws cov hauj lwm ua haujlwm ntau dhau sijhawm, txo cov nqi kho thiab txhim kho qhov kev ntseeg siab tag nrho ntawm cov txheej txheem stamping.

Txhawm rau txhim kho kev ruaj ntseg ntawm cov txheej txheem stamping, ib qho ntxiv muaj zog ua haujlwm tau siv tau. Qhov no suav nrog qhov loj ntawm kev nias ib feem ntawm cov unloading ntxig, ua kom lub siab thov rau cov khoom ntawm cov tuag sab. Cov kev nce siab tau pab txwv cov pob thwj los ntawm kev tig thiab sib ntswg thaum lub sij hawm punching. Qhov kev tawm tsam no tau tshwj xeeb yog muaj txiaj ntsig zoo rau cov khoom uas cov khoom siv tau dhau los vim nws qhov kev ua haujlwm tau yooj yim lossis kev nyuaj siab ntawm cov khoom lag luam stamping. Los ntawm kev muab kev txhawb nqa ntxiv thiab siab, lub zog muaj zog ua kom ruaj khov uas cov khoom tseem ruaj khov rau hauv cov txheej txheem stamping, ua rau muaj cov khoom lag luam zoo dua thiab ntau dua.

Lwm txoj hauv kev zoo los txo cov khoom siv tig thiab distortion yog los txiav bevel lossis arc ntawm ntug punch. Los ntawm kev ntxiv ib bevel lossis arc rau cov punch ntug, cov ntas tsis txiav tawm yog txo qis. Qhov no, nyob rau hauv lem, txo qis tensile quab yuam ntawm cov khoom ntawm cov tuag sab, yog li tiv thaiv cov stamped ib feem ntawm tig rov qab thiab sib txawv. Bevel lossis Arc ua raws li kev ntxhov siab-kev ntxhov siab, tso cai rau cov khoom los cais cov punch ntau dua los ntawm cov punch. Qhov kev hloov kho no tsis tsuas yog txo qis kev pheej hmoo ntawm kev cuam tshuam tab sis kuj tseem ntev lub neej ntawm kev cuam tshuam los ntawm kev txo cov kev quab yuam thaum lub sij hawm txiav. Kev siv qhov no yooj yim hloov pauv hauv kev tsim punch yuav tuaj yeem txhim kho qhov zoo thiab xwm yeem ntawm cov pob khoom siv.

Kev tswj cov npoo ntawm lub punching npoo yog lwm qhov tseem ceeb hauv kev tiv thaiv cov khoom xa thiab distortion. Kev kuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm qhov sib tw ntawm ob qho tib si punch thiab tuag sawv yog qhov tseem ceeb kom zam cov xwm txheej uas hnav nce siab ntau yam kev ntxhov siab ntawm cov khoom. Npub npoo yuav ua rau cov rog tsis sib xws, ua rau cov khoom kom ncab tsis sib xws thiab ua rau muaj kev sib txawv. Los ntawm kev ua kom pom tseeb tias lub plhaw cov npoo tseem nyob ntse, cov rog txiav yog cov neeg faib khoom ntau dua, txo qis ntawm cov khoom deformation. Qhov kev coj ua no tsis yog txhim kho qhov zoo ntawm cov seem xwb tab sis kuj ua rau cov txheej txheem stampiciency los ntawm kev txo qhov kev xav tau ntawm kev rov ua haujlwm thiab seem.

Cov kab sib txawv yog lwm qhov tseem ceeb uas tuaj yeem pab txhawb rau cov khoom xa thiab distortion. Ib qho kev tsis tsim nyog lossis tsis sib haum xeeb sib txawv tuaj yeem ua rau muaj kev cuam tshuam tsis sib haum xeeb thaum lub sijhawm stamping, ua rau deformation ntawm cov stamped seem. Txhawm rau hais txog qhov teeb meem no, nws yog qhov tseem ceeb kom ntseeg tau tias qhov sib txawv yog qhov zoo rau cov khoom siv tshwj xeeb thiab kev ua haujlwm stamping. Qhov no suav nrog kev xav txog yam zoo xws li cov ntaub tuab, hardness, thiab qhov xav tau qhov tseeb ntawm cov khoom kawg. Los ntawm kev tswj cov phiaj xwm thiab tsim nyog xuas nrig ntaus, lub zog thov thaum cov txheej txheem stamping tau muab faib rau ntau, txo qhov kev pheej hmoo ntawm cov khoom xa thiab sib ntswg.

Hauv kev xyaum ntau lawm, cov teeb meem tshwj xeeb xws li oversized los yog undersized punching qhov tseem tuaj yeem ua rau cov ntaub ntawv distortion. Cov teeb meem no feem ntau yog tshwm sim los ntawm kev sib xyaw ntawm cov xwm txheej, suav nrog hnav cov kab xuas nrig, thiab cov duab ntawm ntug punch. Txhawm rau kom zoo rau cov teeb meem no, yuav tsum muaj cov kev kawm txhij txhua. Qhov no muaj kev soj ntsuam ib txwm muaj thiab kev kho kom zoo ntawm cov cuab yeej muaj zog, thiab ua tib zoo xav txog cov punch ntug tsim qauv. Los ntawm kev txheeb xyuas thiab kho cov xwm txheej no, cov chaw tsim khoom tuaj yeem txo qhov tshwm sim ntawm cov khoom siv thiab distortion, txhim kho ob qho kev ua haujlwm tau zoo thiab cov khoom zoo.

Hauv kev xaus, cov ntaub ntawv tig thiab distortion thaum lub sijhawm stamping yog cov teeb meem nyuaj uas yuav tsum tau muaj ntau txoj kev kom nyob tau zoo. Los ntawm kev nkag siab txog qhov pib ua rau, xws li cov cawv ntawm punching quab yuam, pwm tsim, cov tuam ntxhab tuaj yeem ua rau cov teeb meem centermeasures kom siv cov teeb meem no. Cov tswv yim xws li kev ua raws li kev ua ntu zus, kev txhim kho cov cuab yeej siv hluav taws xob, thiab ua kom muaj zog punting cov khoob txhua pab kom txo cov khoom sib txawv. Hauv kev xyaum ntau lawm, tshuaj ntsuam thiab kho cov teeb meem tshwj xeeb raws li cov ntaub ntawv thiab cov lus taw qhia tseem ceeb heev rau kev txhim kho txuas ntxiv. Los ntawm kev kawm cov tswv yim no, cov tuam txhab tsim khoom tuaj yeem tsim kho qhov tseeb thiab qhov zoo tshaj plaws ntawm cov kev ua haujlwm sib luag thiab cov khoom muaj kev ntseeg tau.
