Cov neeg tsim qauv feem ntau siv forging rau cov chaw loj lossis txoj kab uas tsim nyog tsis muaj lossis machining yog qhov chaw pov tseg. Forging yog qhov kev xaiv zoo thaum qhov chaw xav tau kev nyuaj, lub zog, thiab kev ua tau zoo.
Vim li cas thiaj zam tau zoo dua li kev ua pov lossis rov qab xa ncaj qha? Tsuas yog cov chaw loj loj thiab cov khoom uas muaj cov duab nyuaj uas tuaj yeem tau txais kev zam txim, uas tau hais los saum toj no. Forging kuj tseem tuaj yeem txhim kho cov khoom siv, uas muaj ob lub ntsiab lus:
Firstly, forging tuaj yeem txo lossis tshem tawm cov khoom siv khib nyiab, xws li cov khoom tawg, thiab cov khoom txias, thiab cov khoom txias ntawm cov khoom lag luam zoo ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv.
Qhov thib ob, Forging tuaj yeem ua cov feem muaj cov kev taug qab zoo. Feem ntau cov ntaub ntawv nyoos, nyiam cov hlau round, los ntawm dov. Thaum lub sijhawm cov txheej txheem no, cov qauv zeb ntws tawm raws txoj kab nruab nrab. Hauv kev zam txim, cov noob nplej no ntws tawm kom phim cov duab. Qhov kev txhawb zog no tsim cov khoom muaj txiaj ntsig zoo, raws li muaj nyob hauv daim duab hauv qab ..
Machined seem, tsis hais txog lawv tau ua los ntawm cov kab lossis daim hlau, yuav nco ntsoov tua ib feem ntawm cov txheej txheem xim. Qhov no yog vim tias cov nplej ntws yog unidirectional, thiab lub txiaj ntsig qhib xaus ua kom cov khoom siv ntau dua rau kev qaug zog thiab ntxhov siab corrosion tawg. Casting, ntawm qhov tod tes, koom nrog poling molten steel mus rau pwm kom tsim cov khoom lag luam yog cov khoom dawb. Vim tias tsis muaj cov hmoov nplej ntws thaum lub sijhawm no, cov khoom kawg yuav tsis muaj lub zog muaj zog ntxiv. Daim duab hauv qab no muab cov duab kos duab sib piv ntawm peb txoj kev, ua kom yooj yim to taub.
Nov yog qee qhov kev tshawb fawb tshawb fawb rau kev siv: Thaum siv tib cov khoom siv, Forging tuaj yeem ua kom muaj zog ntxiv los ntawm 20% piv rau cov khoom siv lossis cov khoom siv ntshiab. Tom qab forging, cov khoom muaj peev xwm txhim kho los ntawm 30% nyob rau hauv cov nqe lus ntawm lub zog thiab kev sib piv piv rau cov khoom siv raw. Rau tib qho, lub zog tensile ntawm forged ib tug yog 26% siab dua, thiab muaj zog nkees yog 37% siab dua, tshaj li qhov cam.(来源: Imchanics 机械)
