Cov cuab yeej siv cov khoom siv ntawm Q195 cuam tshuam li cas rau nws cov kev siv thev naus laus zis?

Cov khoom siv neeg kho tshuab ntawm Q195 (xws li tsawg depility lub zog, muaj zog sib xws, thiab kev txiav txim siab qis dua nws cov txheej txheem tsim nyog thiab cov txheej txheem kev ua haujlwm. Cov kev cuam tshuam tshwj xeeb yog raws li hauv qab no:
1. Qhov cuam tshuam ntawm cov txiaj ntsig tsawg kom muaj zog (ntau dua lossis sib npaug rau 195 MPa) ntawm kev ua
Cov txiaj ntsig zoo: Cov khoom muaj qhov pib qis dua mus rau cov khoom tawg yooj yim, tso cai rau nws tsis muaj kev ua haujlwm sab nraud (xws li khoov, thiab dov).
For example, when manufacturing lightweight steel keels, Q195 can be bent into complex cross-sections using simple cold-bending equipment, and is less susceptible to cracking due to excessive stress. Thaum stamping nyias -}}}}} kev tuag ntawm cov rog qis, ua rau cov khoom siv tsawg.
NCO TSEG: Vim tias nws cov txiaj ntsig tsawg Zog, deformation yuav tsum tau tswj lub sij hawm ua kom tsis txhob muaj kev sib txawv uas tuaj yeem ua rau muaj kev sib txawv uas yuav ua rau muaj kev sib txawv ntawm cov hlau).
2. Qhov cuam tshuam ntawm kev loj elongation (ntau dua lossis sib npaug nrog 33%) ntawm kev ua
Cov ntsiab lus zoo: Kev du me me tso cai rau nws tiv thaiv cov khoom muaj txiaj ntsig zoo ua ntej tawg, ua kom pom qhov taw qhia tseem ceeb ntawm kev ua haujlwm txias. Txias stamping / sib sib zog nqus teeb duab: haum rau kev tsim cov chaw tsim khoom (xws li cov roj tso tsheb hlau luam thiab ntiav {1} {1/1/u housings). Cov khoom siv ncab uniformes thaum lub nqus cov txheej txheem sib sib zog, muab piv rau kev sib tw hauv zos (uas muaj kev tawg ntawm cov ces kaum kev sib sib zog nqus).
Kev khoov txias: haum rau loj - Lub kaum sab xis khoov (xws li muaj peev xwm tsawg dua), xws li kev sib txuas ntawm scaffolding ncej).
Vuam: cov yas ntawm cov cua sov - qhov kev cuam tshuam loj me me thaum lub sij hawm weld seam txo qhov ua kom tawg. Cov txheej txheem vuam yog qhov yooj yim (tsis muaj preheating lossis complex posts- Weld kev kho mob yuav tsum tau).
III. Qhov kev cuam tshuam ntawm cov tensile muaj zog (315-430 MPa) ntawm kev ua
Lub zog tensile qis txhais tau tias cov khoom tuav cov duab ruaj khov tom qab sib sau, tab sis tsis nce teeb meem vim muaj zog ntau.
Kev txiav: Cov cuab yeej tsis kam ua tsis kam thiab hnav ua nws haum rau high} {{1} -}} tswj nto roughness. Xov ua: thaum tapping lossis yob xov, cov khoom yuav tsis ua rau kev tsim khoom me me, ua kom haum rau kev tsim khoom tsawg {} Lub zog rollingers xws li cov bolts thiab txiv ntoo.
IV. Kev cuam tshuam ntawm tsis muaj hardness (HB 100-130) ntawm kev ua
Tsawg hardness muab kev zoo heev machinity muaj:
Cold colling / cold plhaw: colding colding ntxiv ntxiv cov noob loj thiab txhim kho cov npoo ua tiav (piv txwv li, hauv kev tsim cov khoom lag luam tshiab steel). Txias kos duab txo kev tuag tuag thiab ua kom tau ntau lawm.
Stamping tuag xaiv: Siab - Lub zog tuag (piv txwv li, carbide tuag) tsis tsim nyog; Cov txheej txheem Alloy Steel Dies tuaj yeem ua tau raws li qhov yuav tsum tau ua, txo tus nqi.
V. Cov kev txwv ntawm kev ua
Vim nws lub zog qis, q195 tsis haum rau cov txheej txheem xav tau cov khoom siv siab tom qab ua:
Nws tsis tuaj yeem nce ntxiv nws lub zog los ntawm kev kho mob cua sov xws li quenching (vim nws cov ntsiab lus muaj roj carbon ntau thiab tsis zoo). Yog li ntawd, nws tsis haum rau qhov uas yuav tsum tau ua kom harterening (piv txwv li, zog thiab bearings). Thaum Q195 tuaj yeem tsim los ntawm kev ua haujlwm kub (xws li forging), nws tau txais kev zam txim qis tiv thaiv cov seem los ntawm kev siv hauv cov qauv hnyav {5} Yog li ntawd, kub ua haujlwm tsis tshua siv (ua haujlwm txias yog siv ntau dua).
Ntsiab lus: Kev sib piv ntawm cov khoom siv neeg kho tshuab nrog kev ua tshuab
Q195 cov khoom siv neeg kho tshuab ua rau nws tsim nyog rau kev ua haujlwm txias, ua rau muaj kev ntxhov siab, kev txiav txim siab siv cov nqi qis dua thiab kev ua haujlwm siab. Cov xeeb ceem no tau sib haum nrog nws daim ntawv thov kev tshwm sim thiab niaj hnub ua cov khoom kaw kaw ntawm "}}}}}}} ntawv daim ntawv thov."
