Unformatted text saib ua ntej: Cov txheej txheem ntau deformation txheej txheem Cov txheej txheem ntau deformation Txhais Cov txheej txheem deformation hauv manufacturing yog Deformation kev ua haujlwm uas ua rau muaj kev hloov pauv ntawm cov khoom ua haujlwm los ntawm cov yas deformation nyob rau hauv rog siv los ntawm ntau yam cuab yeej thiab tuag.

Ib yam li ntawd, qhov txheej txheem deformation yog dab tsi?

Cov txheej txheem deformation . Cov txheej txheem deformation hloov cov khoom siv los ntawm ib lub duab mus rau lwm qhov. Thawj cov duab yog feem ntau yooj yim (piv txwv li, ib daim ntawv los yog daim ntawv dawb paug) thiab yog plastically deformed nruab nrab ntawm cov cuab yeej, los yog tuag, kom tau qhov kawg geometry thiab tolerances uas yuav tsum tau muaj (Altan, 1983).

Tsis tas li ntawd, dab tsi yog vim li cas vim li cas cov txheej txheem ntau deformation 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

Nyob rau hauv no hais txog, qhov twg yog qhov yooj yim bulk deformation txheej txheem?

Plaub yooj yim bulk deformation txheej txheem yog (a) dov, (2) forging, (3) extrusion, thiab (4) hlau thiab bar kos duab.

Dab tsi yog qhov sib txawv ntawm cov txheej txheem deformation ntau thiab cov txheej txheem hlau?

Qhov tseem ceeb 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.
