Dab tsi yog qhov cuam tshuam ntawm kev forging txheej txheem ntawm kev lom zem?

lub zog
Qhov av qeeg yog cov tsos ntawm cov vaub kib ntiav ntawm cov kab nrib pleb ntawm kev ua raws li saum npoo. Qhov kev tsis txaus ntseeg no feem ntau yuav tshwm sim ntawm cov chaw nyob hauv qab tensile muaj kev ntxhov siab hauv kev forging kev ua yeeb yam (piv txwv, tsis muaj kev tawm tsam lossis cov khoom khoov).
Cov ua rau sab hauv kev tawg tuaj yeem yog ntau:
① Cov ntsiab lus zoo heev ntawm cov khoom siv raw. Thaum rhuab kub ntev ntev, muaj tooj liab los nag, decarburized, decarburized, lossis saum npoo tau ua kom sov ntau zaus.
Sulfur cov ntsiab lus ntawm cov roj yog dhau lawm, thiab leej faj rau cov khoom ntawm cov khoom siv hlau.
Flash tawg
Flash Crack yog cov kab nrib pleb uas tsim ntawm ib parting nto thaum tuag forging thiab txiav.
Cov teeb meem ntawm flash nrib pleb tej zaum yuav yog raws li hauv qab no:
① Nyob rau hauv kev tuag forging kev ua haujlwm, cov hlau ntws muaj zog vim hnyav percussion.
② Qhov kev txiav tawm ntawm qhov kub ntawm magnesium alloy tuag forging yog tsawg heev; Qhov kev txiav kub ntawm tooj liab riam phom forging yog dhau lawm.
Parting nto tawg
Parting saum npoo av tau hais txog qhov tawg raws li parting nto ntawm kev lom zem. Muaj ntau txhua tus tsis- nws yog xim hlau suav nrog parting tuag saum npoo av thaum ntug yog squeezed thaum tuag tas.
tais
Folding yog tsim thaum cov oxidized cov hlau sib koom ua ke hauv cov txheej txheem ntawm kev deformation hlau. Nws tuaj yeem tsim los ntawm kev sib txuas ntawm ob (lossis ntau dua) cov hlau diav, lossis nws tuaj yeem tsim los ntawm cov hlau nrawm ntawm cov hlau uas nyob ib sab uas nyob ib sab nrog nws. Nws kuj tseem tuaj yeem tsim los ntawm dabtsi yog khoov thiab rov qab ntawm defformed hlau; Nws kuj tseem tuaj yeem yog ib feem ntawm ib feem ntawm cov hlau, uas yog tsim los ntawm kev raug nias rau lwm feem ntawm cov hlau. Folding yog hais txog cov duab ntawm cov ntaub ntawv raw thiab cov khoom siv ntawm cov txheej txheem, thiab tseem siv cov kabmob lubrication, tab sis kuj feem ntau ua ib qho kev ntxhov siab ntawm no.
Dawb -} Streeting
Txaus los ntawm ib daim ntawv ntawm kev faib tawm tsis raug ntawm cov kab ntws. Nyob rau hauv thaj chaw txaus, cov khiav txaus faib ua ke ntawm ib qho kev sib txuas ua ke los ua qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw ntws thiab sab nraud ntawm thaj chaw txaus. Qhov laj thawj rau qhov zoo tshaj plaws yog cov folding, uas yog tsim los ntawm kev zam tshwj xeeb, uas txo tau cov khoom siv ua kom zoo nkauj, uas txo tau cov khoom siv ua kom zoo nkauj, uas txo tau tag nrho cov hlau ua kom loj, uas txo tau ib qho khoom siv zoo nkauj, tab sis cov hlau ua kom loj dua, qhov kev ua tau zoo tshaj plaws.
Qhov Forging Kab tsis yog faib kom zoo
Cov yeeb khiav tawm ntawm Forging tsis yog du, uas txhais tau tias cov kab ntws tawm tsam, Backflow, thiab eddy, thiab eddy tam sim no, tshwm sim ntawm lub sij hawm tsis forging.
Cov txheej txheem FORNING yog qhov tseem ceeb heev; Tsis muaj chaw rau qhov yuam kev me ntsis hauv cov txheej txheem no. Nco ntsoov tias muaj tej yam tsis xws, yog li peb yuav tsum them nyiaj ntau dua thaum zam tau.
