Ntau daim ntawv hlau dabtsi yog khoov thiab tsim cov txheej txheem uas txhua tus tsim pwm yuav tsum paub! Tsim kev sib koom!

Kab lus no yuav qhia txog qee cov txheej txheem hlau dabtsi yog khoov, vam tias yuav pab tau rau txhua tus.

1. Tom qab khoov, vim yog extrusion ntawm cov khoom, hlau yuav bulge ntawm ob sab ntawm khoov, uas ua rau ib tug dav loj dua qhov qub loj. Qhov loj ntawm lub pob yog cuam tshuam nrog lub thickness ntawm cov khoom siv; lub thicker cov khoom, qhov loj lub bulge. Txhawm rau zam qhov tshwm sim no, ib nrab - lub voj voog tuaj yeem ua rau ntawm ob sab ntawm txoj kab khoov ua ntej. Txoj kab uas hla ntawm lub semi- lub voj voog yuav tsum yog yam tsawg kawg yog 1.5 npaug ntawm cov khoom tuab. Tib txoj kev tuaj yeem siv thaum tsim cov ntug khoov.

2. Thaum dabtsi yog khoov daim hlau, lub vojvoog sab hauv (R-lub kaum sab xis) yuav tsum yog qhov zoo tshaj los yog sib npaug rau 1/2 lub thickness ntawm cov khoom. Yog tias tsis muaj R- lub kaum sab xis ua, lub kaum sab xis yuav maj mam ploj tom qab ntau qhov stamping, ib txwm ua ib qho R-angle. Tom qab no, qhov ntev ntawm ib lossis ob sab ntawm R- lub kaum sab xis yuav ntev me ntsis.

3. Sheet hlau yog nquag deformation tom qab khoov. Txhawm rau kom tsis txhob deformation, 45-degree lub kaum sab xis tuaj yeem ntxiv rau ntawm qhov khoov, kom ntseeg tau tias nws tsis cuam tshuam nrog lwm qhov chaw, yog li ua kom nws lub zog.

4. Feem ntau, qhov ntev thiab nqaim ntawm daim ntawv hlau yog qhov nyuaj rau kev ncaj thiab muaj feem ntau rau deformation hauv kev ntxhov siab. Yog li ntawd, peb tuaj yeem khoov lawv mus rau hauv L-puab lossis quav ob sab rau hauv U-puab los tuav lawv lub zog thiab ncaj. Txawm li cas los xij, L-cov duab thiab U- cov duab feem ntau tsis tuaj yeem txuas txij thaum pib mus txog thaum xaus thiab cuam tshuam vim qee yam. Peb yuav tsum ua li cas thaum ntawd? Hauv qhov no, peb tuaj yeem ntxiv qhov tsim nyog ntawm cov tav toj kom nws lub zog.

5. Kev hloov pauv ntawm qhov chaw tiaj tus thiab qhov chaw khoov yuav tsum ua kom muaj lub qhov nqaim lossis qhov qhib uas txuas ntxiv tom qab khoov; txwv tsis pub, burrs yuav tsim. Qhov dav ntawm lub qhov nqaim yuav tsum yog siab tshaj los yog sib npaug li 1.5 npaug ntawm phab ntsa tuab. Tsis tas li ntawd, tsis txhob hnov ​​​​qab kos lub vojvoog (R) lub kaum sab xis thaum kos duab. Cov kaum sab xis thiab cov kaum sab xis hauv cov pwm yog qhov ua rau tawg, thiab thaum cov kab ntau lawm nres, pwm kho yog qhov poob.

6. Ntawm cov ces kaum ntawm cov ntawv hlau, tshwj tsis yog lub kaum sab xis 90-degree, thov xyuas kom lawv raug kho nrog lub vojvoog tsim nyog (R). Cov kaum sab xis ntawm cov npoo ntawm cov ntawv hlau tuaj yeem yooj yim tsim cov ntsiab lus ntse uas tuaj yeem txiav cov neeg ua haujlwm. Hauv cov poj niam pwm, cov ntsiab lus ntse ntawm cov kaum sab xis yog qhov ua rau tawg vim muaj kev ntxhov siab, thiab hauv cov txiv neej pwm, lawv nquag tawg ntawm cov ntsiab lus ntse, yuav tsum tau kho pwm thiab ncua ntau lawm. Txawm hais tias kev tawg tsis tshwm sim, dhau sijhawm, hnav yuav ua rau lub vojvoog (R), ua rau burrs thiab ua rau cov khoom tsis raug.

7. (1) Folding edges tau muab faib ua ib zaug -sab folding thiab ob -sab folding. Yog tias xav tau qhov tseeb, nws yog qhov zoo tshaj los siv ob -sided folding, vim qhov no yuav txhim kho qhov raug. Qhov siab ntawm lub npoo npoo yuav tsum yog siab tshaj 3 hli (t: 1.0-1.2mm). Txwv tsis pub, qhov ntev yuav tsis ruaj khov vim qhov chaw clamping tsis txaus.

7. (2) Thaum folding npoo, qhov chaw los yog sab hauv protrusions ntawm sab phab ntsa yuav tsum tsis txhob nyob ze rau hauv qab nto, nyiam dua ntau tshaj 10mm. Txwv tsis pub, lub kaum sab xis hauv qab ntawm qhov protrusion yuav tsis raug stamped nrog pwm, thiab nws R- lub kaum sab xis yuav loj dua R- kaum sab xis ntawm sab laug thiab sab xis. Lub R-lub kaum sab xis yuav tsis txuas ntxiv, cuam tshuam rau qhov pom. Peb tuaj yeem thwj qhov tsim nyog indentation ntawm txoj kab folding ua ntej khoov kom zoo dua qub.

7. (3) Thaum folding npoo, qhov qhib ntawm sab phab ntsa yuav tsum tsis txhob nyob ze rau ntawm qhov chaw hauv qab, tab sis yuav tsum khaws cia ntawm ntau tshaj 3 hli. Txwv tsis pub, qhov qhib yuav deformed vim yog khoov. Peb tuaj yeem stamp lub qhov ntev ntev nrog qhov ntev tib yam li qhov qhib thiab qhov dav ntawm 1.5mm thickness ntawm kab folding ua ntej khoov. Lub hom phiaj ntawm qhov no yog dab tsi? Nws tuaj yeem txiav tawm qhov nro yam tsis muaj kev cuam tshuam qhov zoo ntawm qhov qhib.

Tom qab nyeem tsab xov xwm no, koj puas tau kawm dab tsi txog tej no?
