Txiav& Dabtsi Yog Khoov Muaj Zog Hlau Hlau Hardox Weldox
Txiab thiab dabtsi yog khoov tshuab yog cov hlau siv cov tshuab ua haujlwm feem ntau rau kev txiav tawm ib lub phaj, khoov rau qee lub tiaj tiaj tiaj rau qee hom nrog qee qhov tsis tu ncua lossis customized punch thiab tuag. Tab sis rau qee qhov siab tensile lub zog steel zoo li SSAB Sweden ua, suav nrog Strenx, Hardox, Weldox thiab Docol cov khoom, nws' s yuav tsum xav txog cov ntsiab lus ntxiv rau cov txheej txheem. Lawv cov hlau tshwj xeeb tsuas yog siv hauvcov chaw tsim khoom ntawm kev thauj khoom hnyav, kev siv tshuab thiab kev tswj cov khoom siv suav nrog kev tsuas thiab kev lag luam rov qab.

NPAJ UA NTEJ YUAV TUAJ YEEM DABTSI
• Txheeb xyuas txoj haujlwm dov ntawm lub phaj. Yog tias ua tau, rov qab uacov kev taw qhia dov mus rau txoj kab khoov. Cov phaj feem ntau tuaj yeem ua rau nruj rau txoj kev no, dua li nrog cov kab khoov sib txuas rau cov kev taw qhia ntxuag.
• Txheeb xyuas qhov zoo ntawm lub phaj. Kev puas tsuaj saum npoo avtuaj yeem paug siab khoovmuaj peev xwm raws li nws tuaj yeem ua rau ntawm pob txha tawg.
Rau cov paib hnyav, qhov tsis xws ntawm lub phaj xws li khawb thiab xeb tuaj yeem raug tshem tawm nrog kev sib tsoo zoo. Qhov sib tsoo khawb yuav zoo dua yog muab tso nrog rau cov kab khoov
• Thermal txiav thiab sheared sawv yuav tsum deburredthiab npawv nrog grinder.
• Txheeb xyuas cov xwm txheej ntawm cov cuab yeej.
• Txhawm rau zam dhau qhov cuab yeej siv ntau dhau, kev siv cuab yeej yuav tsum nyuaj dua
dua li daim ntawv ua haujlwm.
• Txheeb xyuas tias cov cuab yeej thiab cov cuab yeej teeb tsa muaj nyob hauv kab.
RAU TUS TSWV YIM
• Ua zoo saib xyuas kev nyab xeeb thiab ua raws cov lus qhia txog kev nyab xeeb hauv zos. Tsuas yog cov neeg muaj peev xwm ua tau los ntawm los yog ntawm cov tshuab puag ncig. Thaum lub zog siab steel tau raug khoov, tsis muaj leej twg yuav tsum sawv ntawm hauv ntej ntawm nias xovxwm.
• Txheeb tias qhov xuas nrig ntaus ua ke nrog lub haujlwm kis tsis hauv qab hauv qhov tuag.
• Xav txog springback. Zam kev qiv nyiaj ntxiv txhawm rau txhim kho lub kaum ntsej muag profile. Cov kis ntawm ib qho khoom siv rau cov txheej txheem dhau los tsim txoj kev txo nws txoj kev khoov yooj yim rau ntau yam.
• Dabtsi yog khoov quab yuam, lub caij nplooj hlav rov qab thiab, feem ntau, qhov tsawg kawg nkaus pom zoo ntaus nrig vojvoog nce nrog lub zog ntawm cov hlau.
• Feem ntau rau Strenx thiab Hardox phaj cov khoom, indentity ntawm lub phaj yog stamp perpendicular mus rau dov kev taw qhia. Zam kev muab daim phaj tso kom thiaj li pom xwm yeem tshwm sim hauv kab, vim muaj kev pheej hmoo ntawm kev tawg
• Txoj kev tu ncua ntev ntev yuav muaj qhov tsis zoo rau Khoovmuaj peev xwm. Cov lus pom zoo rau Strenx thiab Hardox phaj cov khoom lag luam yog ua raws cov kev ntsuam xyuas nrog cov tshuab ua kom tawg thiab pleev xim rau thaj chaw. Cov lus pom zoo rau Strenx sawb khoom lag luam thiab Docol ua raws li kev ntsuam xyuas yam tsis muaj qhov chaw blasted.
• Ua haujlwm nruj siab tuaj yeem ua rau hauv cheeb tsam qhov kub nce hauv qhov khoov. Qhov no tuaj yeem ua rau muaj kev cuam tshuam tsis zoo ntawm cov khoov taus, tshwj xeeb tshaj yog rau cov tuab ntawm saum 20 hli.
Yog tias ua tau, txo qhov punch nrawm, txhawm rau txo qhov kub qhov sib txawv hauv daim haujlwm ua haujlwm.
Dabtsi Yog Khoov Cuab Yeej
Tuag Dav
Springback nce nrog nce tuag dav dav, thaum lub zog punch txo. Nco ntsoov tias lub kaum sab xis ntawm txoj kev tuag tso cai rau kev txiav ntau dhau, tsis tas tawm hauv qab, kom them nyiaj rau lub caij nplooj hlav rov qab. Kev nce tuag qhib qhov dav tuaj yeem nyob rau hauv ntau kis qis qis txoj hlab ua haujlwm nyob rau hauv qhov khoov. Tsis tas li, nco ntsoov tias muaj ntau chav txaus rau cov punch uas raug xaiv ua ke nrog cov haujlwm, hauv qhov tuag, thaum khoov, tsis cuam tshuam tus tuag. Qhov tsawg kawg nkaus pom zoo tuag qhibDav.
Qhov tuag ntug lub vojvoog yuav tsum yog tsawg kawg ib nrab ntawm cov phaj tuab. Xwb, qhov dav tuag yuav tsum tau nce ntxiv rau hauv kev txiav txim siab mus rau qhov kawg tuag lub vojvoog tuag, thiab yog li txo txoj kev pheej hmoo ntawm tuag cov cim.
Yeeb nrig
Qhov tsim nyog vojvoog ntsuas, nrog rau qhov dav tuag, yog qhov tseem ceeb tshaj plaws. Thaum khoov siab siab lub zog steel, qhov kawg kawg sab hauv lub vojvoog feem ntau yuav me me dua qhov lub vojvoog ntawm cov punch, daim duab 3. Thaum tsis tshua muaj kev sib txhuam ntawm phaj thiab cov cuab yeej, qhov tshwm sim tau pom dua.
Rau cov steel nrog cov zis muaj zog tshaj kwv yees li ntawm 500 MPa, a
tshum qhov sib tshooj uas muaj qhov loj me lossis me dua qhov xav tau
dabtsi yog khoov siv hluav taws xob pom zoo.
CONDITION OF TOOLS
Vim tias muaj qhov sib tiv tauj ntxiv ntawm cov phaj thiab cov cuab yeej thaum khoov siab lub zog steel, hnav ntawm cov cuab yeej nce siab me ntsis. Xyuas ntawm qhov sib nrug, tias qhov punch vojvoog thiab tuag ntug vojvoog yog ob qho tas li. Rau khoov uas tau tawg nyob rau hauv ib qho kev tsim kho, qhov tawg tau ntau zaus ntawm daim ntawv nthuav qhia daim ntawv sab ntawm qhov khoov, daim duab 2. Qhov no feem ntau tuaj yeem raug ntaus nqi rau qhov tsis zoo ntawm qhov punch. Cov npoo ntawm qhov tuag yuav tsum nyob twj ywm huv thiab tsis muaj txheej txheem.
TSHUAB STABILITY
Xav tau cov punch quab yuam feem ntau siab thaum khoov siab siab lub zog steel. Cov txhuam co hluav taws xob zoo li qub feem ntau siab dua li kev sib deev. Qhov no tuaj yeem ua rau lub phaj raug xauv rau ntawm ntug
ntawm ib tus tuag ntug vojvoog, thiab tib lub sijhawm, xaub hla lwm tus. Nyob rau hauv txoj kev no, lub chaw ua haujlwm hloov mus rau qhov tuag hauv txoj kev tsis sib xws thaum txoj kev khoov. Qhov tshwm sim no, hu ua stick-slip, tuaj yeem ua rau cov leeg ntau dua hla qhov khoov. Siv lub tshuab ua kom ruaj khov thiab txav khov kho nrawm nrawm.
Lub tshuab ua kom lub ntsej muag tuag lossis siv lub tshuab sib tsoo tig ib puag ncig tuaj yeem pab tau, zam kev sib dhos thiab ua kom qis qis ntawm lub zog ntaus nrig.
YAJ
Yas kev them nyiaj rau qhov hloov kho ywj ntawm lub tshuab khoov hauv qab ntsaws, Lub hauv nruab nrab ntawm cov punch thiab tuag deflects feem ntau. Los ntawm crowning, lub deflection (C) tau
raug them rau, yog li ua tiav tib lub kaum sab xis raws tag nrho ntev ntev. Yog hais tias qhov khoov profile dhau los ua qhov khoov nkhaus raws txoj kab khoov (B) no tsis tuaj yeem them nyiaj
rau los ntawm crowning. Tom qab unloading compressive kev nyuaj siab tshwm sim nyob rau sab ncab, tib lub sij hawm li tensile kev nyuaj siab tshwm sim nyob rau sab compressed.
Qhov kev ntxhov siab xa tawm ntawm cov phaj tuab ua rau muaj kev txhawj xeeb ntev. Nws yog cov kev nyuaj siab uas nyiam nkhaus qhov profile. Qhov ntau ntawm curvature nyob ntawm flange qhov siab thiab qhov profile tawv. Xav txog kev txiav txim siab ntxiv yuav tsum tau ua thaum teeb tsa cov yas ntawm stepwise dabtsi yog khoov ntawm cov ntawv ntev.
TXIJ NKAWM
Springback nce nrog steel zog thiab qhov piv ntawm tuag dav thiab phaj tuab (W / t). Cov khoom tawm los lub zog muaj qhov loj tshaj plaws.
Thaum khoov, ib qho kev faib tawm cov teeb meem ntxhov siab tau tiav hla ntawm khoov khoov ntu. Lub ncauj lus ntawm kab ntsig yas thiab qhov faib tawm ntawm cov kev ntxhov siab no yuav tswj tus yam ntxwv rau lub caij nplooj ntoo hlav. Txhua lub caij nplooj hlav rov qab yog tag nrho ywj.
Txhawm rau them nyiaj rau kev rov qab hlav, lub cev tuag yuav tsum ua kom zoo li txoj hauv kev puboverbending tsis coining cov khoom.
Nws yog qhov nyuaj heev kom paub tseeb tias lub caij nplooj ntoo hlav ntawm ib qho khoom siv thaum khoov, vim qhov no nyob ntawm ntau yam ntawm txhua lub cuab yeej tshwj xeeb teeb. Yog li ntawd peb thiaj pom zoo kom muaj kev sim siab.
Rau cov phaj thinner lossis daim ntawv (t< 10="" hli),="" kev="" kwv="" yees="" ntawm="" cov="" khoom="">’s springback, nyob rau hauvdegrees, tuaj yeem ua tiav los ntawm kev faib lub zog tensile (MPa) los ntawm 100.
Ib qho kev zam ua ntej yog tias qhov dav tuag yog kwv yees li 10–12 x lub phaj tuab.
PARAMETERS UAS HAIS TIAS TXHUA YEEM SPRINGBACK:
• Ua tau lub zog ntawm cov khoom siv–siab dua cov zis muaj zog ua rau lub caij nplooj ntoo hlav ntau dua.
• Punch vojvoog–qhov siab vojvoog ntau zuj zus yuav ua rau muaj kev rov qab caij nplooj ntoos hlav ntau dua.
• Tuag dav–loj dua qhov dav tuag ua rau lub caij nplooj ntoo hlav ntau dua.
• Txoj kev ua kom nruj ntawm cov khoom siv.
Strenx thiab Hardox yog xa nrog lav tau txais kev ua tau zoo raws li Strenx thiab Hardox guarrantee.
