Qhov txawv ntawm kev ua haujlwm txias thiab kub ua haujlwm

Qhov sib txawv ntawm kev ua haujlwm txias thiab ua haujlwm kub

Kev ua haujlwm txias feem ntau yog hais txog kev txiav cov hlau. Ib txheej txheem uas cov txheej txheem ntau dhau ntawm cov khoom raug tshem tawm los ntawm qhov khoob lossis cov khoom ua haujlwm nrog cov cuab yeej txiav, suav nrog cov cutters, abrasives thiab abrasives, kom tau txais cov lus teev tseg, qhov loj me thiab qhov zoo ntawm lub workpiece. Txhua txoj kev txiav yuav tsum muaj peb yam kev mob: lub cuab yeej txiav, lub workpiece thiab txiav cov lus tsa suab. Cov cuab yeej txiav yuav tsum muaj qhov txiav, thiab nws cov khoom yuav tsum nyuaj dua li cov khoom ua haujlwm. Cov cuab yeej sib txawv thiab cov ntaub ntawv txiav cov lus tsa suab yog sib txawv txoj kev txiav. Cov txheej txheem txiav nrog cov hniav ruaj khov thiab cov cuab yeej txiav muaj xws li tig, drilling, tho txawv, milling, npaj, broaching thiab sawing, thiab lwm yam. Sib tsoo, sib tsoo, honing thiab polishing yog cov txheej txheem ntawm kev txiav nrog cov cuab yeej abrasive lossis abrasives nrog cov hniav tsis zoo. thiab tus lej. Kev ua haujlwm txias tuaj yeem ua rau tsis xav tau. Xws li ib qho kev txo qis hauv ductility thiab nce hauv kev ntxhov siab residual. Txij li cov txheej txheem ntawm kev ua haujlwm txias lossis kev ua haujlwm tawv tawv yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua haujlwm yog qhov ua kom muaj zog ntawm kev ua haujlwm hnyav, txhua txoj kev kho mob uas tuaj yeem hloov kho lossis tshem tawm qhov cuam tshuam tuaj yeem tshem tawm cov kev ua haujlwm txias. Nyob rau hauv metallogy, cov txheej txheem saum toj no lub recrystallization kub ntawm cov hlau yog hu ua kub ua hauj lwm. Kev ua haujlwm kub tuaj yeem muab faib ua hlau casting, kub dov, forging, vuam thiab hlau kho cua sov thiab lwm yam txheej txheem. Qee zaum thermal txiav, thermal txau thiab lwm yam txheej txheem suav nrog. Kev ua haujlwm kub tuaj yeem txhim kho microstructure ntawm hlau qhov chaw thaum tsim, lossis hloov lub xeev crystallization ntawm cov khoom tsim los txhim kho cov khoom siv ntawm cov khoom. Casting thiab vuam yog lub melting thiab solidification ntawm hlau. Qhov sib txawv tseem ceeb ntawm kev ua haujlwm txias thiab ua haujlwm kub yog raws li hauv qab no:

Ua ntej, txawv lub hom phiaj

1.kev ua haujlwm txias: txhim kho hardness thiab lub zog ntawm lub workpiece.

2.kev ua haujlwm kub: txhim kho cov khoom siv kho tshuab ntawm lub koom haum.

Ob, txoj kev sib txawv

1.Cold processing: yas deformation ntawm hlau ntawm qis dua recrystallization kub ua tshuab.

2.Hot processing: Cov txheej txheem ua cov yas deformation thiab recrystallization ntawm cov ntaub ntawv hlau nyob rau tib lub sij hawm nyob rau hauv cov xwm txheej ntawm siab tshaj qhov kub ntawm recrystallization.

Peb, cov txheej txheem suav nrog txawv

1.Cold processing: xws li txias dov, txias kos duab, txias forging, stamping, txias extrusion thiab hais txog.

2.Kev ua haujlwm kub: Kub ua haujlwm feem ntau suav nrog casting, forging, vuam, kho cua sov thiab lwm yam txheej txheem.

Peb lub tuam txhab tshwj xeeb hauv kev ua cov kub dov, kos duab txias, tsim cov tshuab txias txias, yog tias xav tau, txais tos sab laj!
