Dab tsi ua rau khawb ntawm cov hlau stamped qhov chaw?

1. Muaj khawb ntawm cov hlau stamped qhov chaw. Lub ntsiab yog vim li cas rau khawb ntawm qhov chaw yog: ntse khawb ntawm cov pwm los yog hlau plua plav nkag mus rau hauv pwm. Kev tiv thaiv muaj xws li xuab zeb tawm khawb ntawm cov pwm thiab tshem tawm cov plua plav hlau.
2. Lub hauv qab ntawm ib feem yog tawg. Cov laj thawj tseem ceeb ntawm kev tawg ntawm qhov qis ntawm ib feem yog: cov khoom tsis zoo ductility lossis cov pwm tuav yog nias heev. Kev tiv thaiv muaj xws li hloov cov khoom siv nrog cov yas ntau dua los yog ua rau cov neeg ua haujlwm tsis muaj zog.
3. Muaj folds ntawm sab phab ntsa ntawm cov khoom. Lub ntsiab ua rau folds ntawm sab phab ntsa ntawm qhov chaw yog: tsis txaus thickness ntawm cov khoom (thinner tshaj li qhov tsawg kawg nkaus tso cai thickness) los yog lub sab sauv thiab sab pwm yog ntsia eccentrically, uas ua rau ib tug loj sib txawv ntawm ib sab thiab ib tug me me qhov sib txawv ntawm lub lwm sab. Kev tiv thaiv muaj xws li kev hloov tam sim ntawm cov khoom siv thiab kev hloov kho cov duab.
4. Qhov chaw tsis nyob siab txaus. Cov laj thawj rau qhov siab tsis txaus ntawm qhov chaw thiab kev ntsuas los tiv thaiv lawv yog raws li hauv qab no:
1) Qhov loj ntawm cov ntaub plaub yog tsis txaus rau stamping hlau qhov chaw. Lub sijhawm no, qhov loj ntawm lub tsho loj yuav tsum tau nce ntxiv.
2) Qhov sib txawv pwm loj heev. Lub sijhawm no, cov duab yuav tsum tau txiav.
3) Cov khoom ntawm cov hlau stamped qhov chaw tsis zoo ductility. Nyob rau lub sijhawm no, kev kho annealing yuav tsum tau nqa los yog cov khoom siv nrog cov ductility zoo dua yuav tsum tau hloov.
