Tus yuam sij qhov sib txawv ntawm tej deformation thiab daim hlau forming yog nyob rau hauv ntau deformation , qhov chaw ua hauj lwm muaj ib cheeb tsam tsawg rau ntim piv whereas, nyob rau hauv daim hlau tsim, thaj tsam rau ntim piv yog siab. Cov txheej txheem deformation Nws yog ib qho tseem ceeb rau kev hloov ib qho khoom ntawm cov khoom siv rau hauv ib qho khoom.

Nyob rau hauv no hais txog, dab tsi yog cov txheej txheem hlau sib txawv?

Feem ntau, hlau txheej txheej txheem tuaj yeem muab faib ua ob pawg dav. Ib qho yog bulk tsim thiab lwm yam yog daim ntawv hlau ua . Bulk deformation yog hais txog kev siv cov khoom siv raw rau tsim uas muaj qhov tsawg ntawm qhov chaw rau qhov ntim piv. Rolling, forging, extrusion thiab kos duab yog ntau tsim cov txheej txheem.

Kuj Paub, qhov txawv ntawm qhov sib sib zog nqus nqus thiab kos duab bar yog dab tsi? Teb. Daim duab sib sib zog nqus yog ib daim ntawv hlau tsim cov txheej txheem siv los tsim cov khob zoo li qhov; bar kos duab yog ib txoj kev deformation ntau siv los txo txoj kab uas hla ntawm lub cylindrical workpart.

Ib tug kuj tseem nug, dab tsi yog vim li cas vim li cas cov txheej txheem deformation ntau tseem ceeb?

Yog vim li cas vim li cas cov txheej txheem ntau deformation tseem ceeb suav nrog cov hauv qab no: (1) lawv muaj peev xwm tseem ceeb Cov kev hloov pauv thaum siv kub ua haujlwm, (2) lawv muaj txiaj ntsig zoo ntawm kev siv zog thaum ua haujlwm txias, thiab (3) feem ntau ntawm txheej txheem tsim cov khoom pov tseg me me; ib co yog net shape txheej txheem

Dab tsi yog bulk deformation?

• Kev ua haujlwm uas ua rau muaj kev hloov pauv ntawm cov hlau. workpiece los ntawm yas deformation nyob rau hauv rog siv. los ntawm ntau yam cuab yeej thiab tuag.
