Taw qhia
Nyob rau hauv lub ntiaj teb no ntawm metalworking thiab manufacturing, forging yog ib tug siv ntau txoj kev los tsim thiab ntxiv dag zog rau cov hlau. Nrog nws cov hauv paus hniav rov qab ntau txhiab xyoo, forging tau hloov zuj zus mus rau ntau txoj kev sib txawv, txhua tus muaj nws tus kheej zoo thiab qhov tsis zoo. Hauv tsab xov xwm no, peb yuav tshawb txog qee qhov feem ntau siv forging txoj kev thiab sib tham txog lawv qhov zoo thiab qhov tsis zoo.
Kub Forging
Ib txoj hauv kev qub tshaj plaws thiab feem ntau cov txheej txheem forging yog kub forging. Raws li lub npe qhia, kub forging muaj cua sov cov hlau saum toj no nws recrystallization kub (feem ntau ntawm 950 degree thiab 1250 degree) ua ntej shaping nws. Txoj kev no muaj ntau yam txiaj ntsig. Ua ntej, kub forging tso cai rau cov yas zoo dua ntawm cov hlau, uas ua rau muaj zog formability thiab txo qhov tawg. Tsis tas li ntawd, kub forging txhim kho cov khoom siv ntawm cov hlau, ua rau nws muaj zog thiab ruaj khov dua.
Txawm li cas los xij, nrog rau cov txiaj ntsig zoo tuaj ob peb qhov tsis txaus. Kub forging yuav tsum muaj ntau lub zog los ua kom sov cov hlau, ua rau cov nqi ntau lawm. Tsis tas li ntawd, qhov kub siab tuaj yeem ua rau oxidation thiab scale tsim ntawm cov hlau nto, ua rau muaj teeb meem zoo. Txawm hais tias cov teeb meem no, kub forging tseem yog ib txoj kev siv dav vim nws lub peev xwm los tsim cov duab nyuaj nrog cov khoom siv txhim kho.
Txias Forging
Nyob rau hauv sib piv rau kub forging, txias forging yog hais txog cov txheej txheem ntawm shaping hlau nyob rau hauv chav tsev kub los yog me ntsis saum toj no. Txias forging muaj ntau qhov zoo dua li kub forging. Ua ntej, nws tshem tawm qhov xav tau ntawm preheating, txo kev siv hluav taws xob thiab cov nqi tsim khoom. Thib ob, txias forging ua rau saum npoo zoo kawg nkaus tsis muaj oxidation lossis scaling teeb meem. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas zoo nkauj yog qhov tseem ceeb, xws li cov hniav nyiaj hniav kub lossis cov khoom siv kho kom zoo nkauj.
Txawm li cas los xij, txias forging muaj qee qhov kev txwv. Qhov tsis muaj cua sov thaum lub sijhawm txheej txheem txwv cov yas ntawm cov hlau, ua rau nws tsis yooj yim dua piv rau kub forging. Cov duab nyuaj nrog cov ntsiab lus sib txawv yog qhov nyuaj dua kom ua tiav siv cov txheej txheem txias forging. Tsis tas li ntawd, cov khoom siv hluav taws xob ntawm cov hlau yuav tsis raug kho kom zoo dua li hauv kub forging. Txawm hais tias cov teeb meem no, txias forging tseem nrov rau nws cov nqi-zoo thiab qhov zoo ntawm qhov tiav.
Kub Forging
Raws li lub npe qhia, sov forging yog ib txoj kev uas muab cov ntsiab lus ntawm ob qho tib si kub thiab txias forging. Nws suav nrog kev tsim cov hlau ntawm qhov kub ntawm 550 degree thiab 950 degree. Sov forging muaj qhov sib npaug ntawm qhov zoo ntawm qhov kub thiab txias forging. Qhov kub nruab nrab tso cai rau kev txhim kho plasticity thaum txo kev siv hluav taws xob piv rau kub forging.
Txawm li cas los xij, sov forging kuj muaj qee qhov tsis zoo. Qhov ntsuas kub yuav tsum tau nqaim dua li qhov kub forging, ua rau nws nyuaj rau kev tswj. Tsis tas li ntawd, sov forging yuav tsis muab tib theem ntawm txhua yam muaj zog thiab durability li kub forging. Txawm hais tias cov kev txwv no, qhov sov sov forging tau txais koob meej vim nws lub peev xwm los tsim cov khoom zoo ntawm tus nqi txo.
Hauv kev xaus, kev xaiv ntawm txoj kev forging nyob ntawm ntau yam xws li cov duab xav tau, cov khoom siv, thiab cov nqi txiav txim siab. Kub forging muaj cov formability zoo heev thiab txhim kho cov khoom siv dag zog ntawm kev siv zog ntau dua. Txias forging, ntawm qhov tod tes, muab cov nqi txuag thiab ua kom zoo tshaj plaws, txawm tias muaj kev txwv tsawg. Thaum kawg, sov forging ntaus sib npaug ntawm ob tab sis yuav tsis ua tiav tib theem ntawm lub zog li kub forging.
Kev nkag siab txog qhov zoo thiab qhov tsis zoo ntawm txhua txoj kev forging yog qhov tseem ceeb rau cov neeg tsim khoom los txiav txim siab paub txog cov txheej txheem twg los ua haujlwm. Nrog rau kev txhim kho txuas ntxiv hauv thev naus laus zis thiab metallurgy, peb tuaj yeem cia siab tias yuav ua kom zoo dua ntxiv thiab txhim kho txoj hauv kev forging, ua rau cov khoom siv ntau dua thiab cov khoom siv hlau zoo.
