Kev xaiv ntawm cov khoom ntuag rau Lub Tshuab Xauv

Qhov xav tau ntawm cov khoom siv twj cuab yeej Thaum ua lub tshuab hlau loj, lub tshuab txiav yuav tsum muaj lub zog thiab ua kom nruj kom tsis txhob muaj kev sib tham thiab deformation thaum lub sijhawm txiav vim cov txiav loj loj. Qhov no yuav tsum tau xaiv qhov tsim nyog ntawm qhov chaw hla loj ntawm cov shank, thiab tib lub sijhawm, shank yuav tsum tau ua los ntawm cov khoom muaj zog dua, xws li quenched thiab tempered 45 steel lossis {{{3} } hlau.

Qhov xav tau ntawm cov khoom ntawm qhov txiav ntawm qhov cuab yeej Thaum ua lub tshuab hlau stainless, cov khoom siv ntawm cov txiav ib feem ntawm lub cuab yeej yuav tsum muaj ntau dua hnav tsis kam thiab tswj nws qhov kev ua tau zoo ntawm qhov kub siab dua. Cov ntaub ntawv siv tam sim no yog: kev kub ceev steel thiab cemented carbide. Vim hais tias kev kub ceev steel tsuas tuaj yeem tswj tau nws qhov kev txiav hauv qab 600 ° C, nws tsis tsim rau kev txiav tawm high-speed, tab sis tsuas yog ua cov hlau tsis muaj hluav taws xob tsawg. Vim tias cemented carbide muaj cov tshuaj tiv thaiv tshav kub zoo dua thiab hnav tsis kam dua li kev siv cov hlau loj, cov cuab yeej ua los ntawm cov ntaub ntawv cemented carbide zoo dua rau kev txiav cov hlau tsis huv.

Carbide tau muab faib ua tungsten-cobalt alloy (YG) thiab tungsten-cobalt-titanium alloy (YT). Lub tungsten-cobalt alloy muaj zoo toughness. Cov cuab yeej tuaj yeem ua nrog lub zog kib loj dua thiab lub qhov muag ntse kawg. Thaum lub sijhawm txiav cov txheej txheem, lub nti tau yooj yim deformed, kev txiav yog lub teeb, thiab nti tsis yooj yim lo rau riam, yog li nws feem ntau Hauv qhov no, nws yog qhov tsim nyog dua los ua cov ntawv hlau nrog tungsten-cobalt alloy. Tshwj xeeb tshaj yog nyob rau hauv ntxhib machining thiab sib quas ntus txiav nrog lub siab kev co, tungsten-cobalt alloy hniav yuav tsum tau siv. Nws tsis yog qhov nyuaj thiab nkig li tungsten-cobalt-titanium alloy, uas tsis yooj yim rau ntse thiab yooj yim nti. Tungsten-cobalt-titanium alloy muaj zoo dua ua tawv tawv liab thiab hnav tsis kam dua li tungsten-cobalt alloy nyob rau hauv qhov kub siab, tab sis nws yog nkig thiab tsis tiv taus cuam tshuam thiab kev co. Nws feem ntau siv los ua tus kav hlau stainless precision tig tuam.

Kev txiav cov cuab yeej ua tiav tau cuam tshuam nrog kev ua haujlwm ruaj khov thiab tsim muaj txiaj ntsig, thiab kev tsim tawm ntawm cov khoom siv cuam tshuam rau kev tsim khoom thiab ua kom zoo dua ntawm cov twj nws tus kheej. Nws raug nquahu kom xaiv cov cuab yeej cov khoom siv nrog lub siab tawv, zoo adhesion tsis kam thiab tawv, xws li YG cemented carbide, nws yog qhov zoo tshaj plaws tsis siv YT cemented carbide, tshwj xeeb tshaj yog thaum ua tiav 1 Gr 18 Ni {{ 2}} Ti austenitic stainless hlau, YT cemented carbide yuav tsum zam kiag li Alloys, vim tias titanium (Ti) hauv cov hlau tsis xeb thiab Ti hauv YT cemented carbide tsim kev sib txuam, txiav cov nti yooj yim tshem Ti tawm ntawm cov hlau, uas txhawb nqa nce cov cuab yeej hnav. Kev ua ntau lawm qhia tau hais tias kev xaiv ntawm peb qib ntawm cov khoom siv, YG 532, YG 813 thiab YW 2, rau kev ua cov hlau tsis xeb muaj kev ua tau zoo dua
