1.How ua cov peev txheej substrate cuam tshuam rau cov txheej txheem?
Tso lub zog thiab elongation:
Lub substrate nrog cov txiaj ntsig tsawg zog muaj zog thiab elongation muaj yooj yim dua, tsis yooj yim tawg thaum khoov lossis stamping rau kev sib sau.
Lub siab-zog steel substrate nrog siab tawm lub zog muaj zoo rigidity tab sis cov kua nplaum muaj txiaj ntsig, uas haum rau kev tsim cov. Kev khoov rau ntau dhau yog qhov tsis tshua muaj rau "rebound" lossis substrate tawg.
Cov yam ntxwv ntawm cov nqi: Qhov kub-dip galvanized txheej yog softer thiab muaj kev sib luag zoo. Nws tsis yooj yim rau tawg thaum tsim thiab tsim nyog rau kev ua nrog kev khoov cov hluav taws xob me me.
Aluminium-zinc txheej muaj cov txhuas, zinc, thiab silicon alloys, muaj ntau dua hardness thiab me ntsis tsis zoo. Kev khoov tsoo ntau dhau yuav ua rau txheej txheej kom tawg, thiab kev khoov hluav taws xob hluav taws xob yuav tsum tau tswj hwm.
2.Yog ua cov txheej txheej cuam tshuam rau cov txheej txheem?
Yooj taus: qhov txheej yuav tsum muaj qee yam elasticity thiab muaj peev xwm ncab nrog deformation ntawm substrate. Lub "T-Bend xeem" feem ntau yog siv rau kev ntsuam xyuas: Tom qab cov coil yog khoov li ntawm qhov hluav taws xob tsawg kawg nkaus uas cov txheej tsis tawg, qhov zoo dua.
Qhov sib txawv ntawm cov txheej txheem sib txawv: polyester (xws li pvdf txheej polyester yog qhov tsim nyog rau cov khoom sib xyaw nrog phab ntsa sab nrauv).
Adhesion: Qhov sib txuas lus sib txuas ntawm cov txheej thiab cov txheej txheem yuav tsum muaj zog kom tsis txhob muaj cov xim tev vim kev ncab thaum lub sijhawm ua haujlwm. Cov kev sim ua ntu zus "yog ntsuas: Siv tus hniav rau kos tus ntoo khaub lig los rhuav nws tawm. Cov txheej txheej tshuaj yog tsawg dua 5% kom tsim nyog. Tsawg dua nws peels tawm, zoo dua adhesion.
Hardness: Yog tias lub hardness ntawm txheej yog dhau lawm, nws yog qhov yooj yim los ua brittle thiab tawg thaum ua; Yog tias nws qis dhau, nws yooj yim rau kos. Nws yog ib qho tsim nyog kom sib npaug hardness thiab yooj. Feem ntau, lub hardness ntawm cov xim coils rau cov khoom siv hauv tsev yog tswj tau ntawm H-2H, thiab rau kev tsim kho yog tswj hwm ntawm 2H-3H.
3.Yuav machinery tshuab cuam cuam tshuam machining ua tau zoo?
Dab tsi yog khoov radius (r): qhov me dua khoov xaim hluav taws xob, qhov ntau dua lub tensile deformation ntawm substrate thiab txheej, thiab ntau dua cov txheej yuav tawg; Conversely, ib qho kev khoov dua hluav taws xob hluav taws xob tuaj yeem txo kev txhawj xeeb txog kev ntxhov siab thiab txo qhov tsis xws luag.
Sib furing ceev: thaum lub sijhawm ceev ceev lossis stamping yog nquag mus khawb thiab tev vim kev sib txhuam tau los ntawm kev txhuam hniav lossis cov roj nplua nyeem uas haum rau kev ua kom nrawm.
Pwm Tsim: Yog tias lub pwm hluav taws xob me me me me heev, nws yuav ua kom tsis txhob muaj kev ua kom cov txheej txheej. Ib pwm nrog lub vojvoog ntawm ntau dua lossis sib npaug rau 2 hli yuav tsum tau siv los txo cov txheej txheem sib txhuam nrog cov txheej.
4.Qhov dab tsi yog qhov sib txawv ntawm cov kev ua kom muaj cov xwm txheej sib txawv?
Yooj yim ua
Txoj kev ua: Rolling rau hauv cov kab hla sib txuas nrog corrugation thiab trapugation thiab trapezoid, deformation yog qhov yuav tsum tau ua yog qhov nruab nrab.
Yuav tsum muaj: substrate elongation ntau dua los yog sib npaug rau 20%, txheej t-bend kuaj ntau dua los yog sib luag yam tsis muaj kab nrib pleb muaj ntau dua lossis sib npaug rau 4b.
Nruab Nrab Sib Sau
Txoj kev ua: 90℃folding, ntiav stamping, loj loj deformation.
Yuav tsum muaj: substrate elongation ntau dua los yog sib npaug rau 1t qhov tob tob dua lossis sib npaug ntawm 6 hli, xyuas kom meej tias cov txheej sib luag tsis poob ntawm ntug.
Txoj kev ua txoj kev nyuaj
Txoj kev ua: sib sib zog nqus stampy, tensile deformation, qhov tseem ceeb heev rau cov plastenate yas thiab txheej yooj yim.
Yuav tsum muaj: substrate elongation ntau dua los yog sib npaug rau cov kab nrib pleb
5.Qhov yog cov kev ntsuas los txhim kho kev ua lag luam tau zoo?
Kev xaiv substrate: ua ntej substrates nrog cov khoom tsis tshua muaj zog thiab muaj kev vam meej DC51D + Z (kub-dip galvanized) lossis SPCC (txias-dov daim ntawv).
Txheej Txheej Haum: Xaiv ib txheej txheej txheej nrog kev hloov pauv tau zoo dua qub, xws li cov qauv yas (thawj-txheej txheem qauv nplaum (Primer txhim kho adsures hloov tau).
Txheej Txheem Txhim Kho:
Nce txoj kev khoov hluav taws xob (xws li thaum 1t rau 2t) kom txo qis kev cuam tshuam hauv zos;
Siv cov roj nplua nyeem tshwj xeeb (xws li cov dej lim dej) thaum lub sijhawm ua kom txo kev sib txhuam ntawm cov txheej thiab pwm;
Txo cov qauv nrawm (xws li yob nrawm los ntawm 30m / min rau 20m / min) kom zam dhau kev ntxhov siab.
