Cov txheej txheem ua thiab cov yam ntxwv ntawm cov kav dej khoov thiab cov kav dej tsis tu ncua:
Raws li kev tsim khoom, cov kav dej khoov tuaj yeem muab faib ua mandrel bent kav, stamping bent kav, thiab welded bent kav. Mandrel khoov kav dej tuaj yeem muab faib ua cov kav dej txias mandrel khoov thiab cov kav dej kub mandrel khoov. Cov kav dej khoov yog cov yeeb nkab fittings siv los hloov cov kev taw qhia ntawm lub raj xa dej thiab feem ntau siv rau ntawm cov yeeb nkab kawg thiab cov junctions.
Mandrel khoov kav dej muaj qhov zoo ntawm ductility zoo heev, siab ua haujlwm siab, thiab tsis muaj zog. Yog li ntawd, lawv feem ntau siv hauv kev tsim kho. Cov ntaub ntawv ntawm cov kav dej khoov muaj xws li lub luj tshib, U-zoo li lub luj tshib, pem hauv ntej thiab nraub qaum, thiab lub luj tshib arc. Kev khoov rau pem hauv ntej thiab rov qab yog ib qho khoom siv nrog ob lub luj tshib. Qhov kev ncua deb ntawm qhov nruab nrab ntawm qhov khoov kawg, hu ua qhov siab ua ntej thiab tom qab kev sim khoov, yog qhia los ntawm tsab ntawv "h." Thaum lub rhaub chamber yog perpendicular mus rau lub radiator txuas nrog lub ntsiab thiab ceg kav, nws tsis ua kev sib cuag nrog lub ntsej muag ntawm tib connector ntawm lub radiator thiab feem ntau yuav tsum tau khoov rov qab.
U-shaped yeeb nkab yog cov yeeb nkab haum nrog cov duab semicircular. Qhov kev ncua deb "d" nruab nrab ntawm cov kab nruab nrab ntawm ob qhov kawg ntawm cov yeeb nkab yog ob zaug ntawm qhov khoov vojvoog "R." U-shaped kav yuav siv tau los hloov ob lub luj tshib 90 degree thiab feem ntau yog siv los txuas ob lub vertically teem radiators. Arc bent kav yog cov yeeb nkab fittings nrog lub kaum sab xis sib txawv, nrog lub kaum sab xis ntawm 90 degree thiab sab kaum ntawm 135 degree. Arc bent kav yog siv los hla lwm cov kav dej, thiab lawv feem ntau yog siv hauv cov kav dej uas muab dej kub thiab txias. Qhov ntev ntawm cov kav dej khoov yog nyob ntawm cov yeeb nkab txoj kab uas hla, khoov lub kaum sab xis, thiab khoov vojvoog. Lub kaum sab xis yog txiav txim siab raws li qhov tseeb ntawm qhov chaw tsim kho thiab cov duab kos, thiab cov qauv siv los kuaj xyuas lub kaum sab xis ntawm cov yeeb nkab kom ua tau raws li qhov yuav tsum tau ua.
Cov txheej txheem ua rau cov kav dej tsis tu ncua sib txawv ntawm cov kav dej tuab-walled bent. Vim muaj kev lag luam sib txawv hauv Suav teb, cov khoom tsim, nrog rau cov kav dej, tau ua ntau yam. Yog tias ib yam khoom tsis tuaj yeem ua tau raws li kev xav tau ntawm kev lag luam, cov kav dej tsis tu ncua yog tsim. Nyob ntawm txoj kab uas hla ntawm qhov tsim cov yeeb nkab tsis tu ncua, nws tuaj yeem muab faib ua ib qho kev sib sau thiab ntau-stamping txoj kev. Lub shrinkage forming txheej txheem ntawm irregular bent kav yuav tsum tau muab ib tug dawb paug nrog ib txoj kab uas hla sib npaug zos rau txoj kab uas hla ntawm cov yeeb nkab rau hauv txoj kev tuag. Cov hlau yog extruded raws qhov tuag kab noj hniav los ntawm kev siv lub siab nyob rau hauv cov kev taw qhia ntawm lub hom phiaj nyob rau hauv lub axial ntawm lub dawb paug rau daim ntawv thiab shrink nws. Lub expansion forming ntawm steel blanks yog hais txog cov ntaub ntawv uas txoj kab uas hla ntawm cov hlau dawb paug yog me dua qhov sib txawv diameters, thiab txoj kab uas hla ntawm qhov kawg ntawm lub bent yeeb nkab yog txais.
Cov txheej txheem nthuav dav yog tsom rau txoj kab uas hla sib txawv ntawm qhov sib txawv diameters thiab tsis yooj yim shrunk. Qee zaum, raws li kev xav tau ntawm cov khoom siv thiab cov khoom tsim, kev nthuav dav thiab kev cog lus yog ua ke. Txawm li cas los xij, tsis muaj cov txheej txheem stamping, cov khoom siv tsawg tsawg, thiab tsis tas yuav muaj cov khoom siv cua sov ntxiv los ua cov tuab tuab tuab. Yog li ntawd, stamping yog ib qho khoom-txuag thiab txuag hluav taws xob ua. Tsis tas li ntawd, tus nqi ntawm cov khoom stamped yog qhov tsawg, ua rau txoj kev no nrov ntawm cov tuam ntxhab.
Nyob rau hauv lub stamping txoj kev ntawm tuab-walled bent kav, cov tuag ua kom lub qhov ntev thiab cov duab raug ntawm cov stamped qhov chaw thiab feem ntau tsis ua puas lub nto zoo ntawm lub stamped qhov chaw. Cov tuag nta lub neej ntev kev pab cuam, ruaj khov stamping zoo, thiab zoo interchangeability. Nws yog ib qho yooj yim rau mechanize thiab automate.
SINO SPECIAL METAL muab ntau hom thiab cov ntaub ntawv ntawm cov yeeb nkab fittings, flanges, thiab cov kav dej. Peb yog cov chaw tsim khoom lag luam txhim khu kev qha, thiab peb txais tos cov lus nug thiab kev yuav khoom.
