Kev kos duab kho vajtse yog txheej txheem hlau ua haujlwm siv los tsim ntau yam khoom kho vajtse. Cov txheej txheem kos duab kho vajtse suav nrog kev siv lub zog tensile rau cov ntaub ntawv hlau kom ua rau cov yas deformation, yog li hloov lawv cov duab thiab qhov loj me. Cov txheej txheem feem ntau suav nrog cov kauj ruam hauv qab no:
Kev npaj khoom siv: Xaiv cov khoom siv hlau tsim nyog, xws li steel lossis aluminium, thiab txiav thiab ua ntej - kho lawv raws li cov khoom yuav tsum tau npaj rau kev ua haujlwm tom ntej.
Tuag Design thiab Manufacturing: Tsim thiab tsim kev kos duab tuag raws li cov duab thiab qhov loj ntawm cov khoom. Cov tuag feem ntau muaj cov sab sauv thiab qis qis, thiab kev ncab ntawm cov khoom siv hlau yog ua tiav los ntawm kev qhib thiab kaw ntawm qhov tuag.
Cua sov thiab Preheating: Ua kom sov cov khoom siv hlau mus rau qhov kub thiab txias kom nws cov plasticity thiab deformability. Preheating tuaj yeem txo qhov kev ntxhov siab thiab deformation hauv cov khoom.
Kev kos duab: Muab cov khoom siv hlau preheated rau hauv qhov tuag thiab siv lub zog tensile siv tshuab lossis hydraulic siab, ua rau cov khoom siv yas deformation. Thaum lub sij hawm kev kos duab, nws yog ib qho tsim nyog los tswj qhov loj thiab ceev ntawm lub zog tensile los xyuas kom meej cov khoom zoo thiab qhov tseeb.
Cooling thiab Annealing: Tom qab kos duab, cov khoom siv hlau yuav tsum tau txias thiab annealed kom tshem tawm cov kev ntxhov siab sab hauv thiab kho nws cov khoom siv kho tshuab. Kev ua kom txias tuaj yeem ua tiav los ntawm kev ua dej txias lossis cua txias, thaum annealing muaj cua sov cov khoom mus rau qhov kub thiab txias, tuav nws rau lub sijhawm, thiab tom qab ntawd maj mam txias.
Post{0}}Kev ua haujlwm: Cov khoom kos tuaj yeem xav tau kev ua haujlwm ntxiv, xws li txiav, xuas nrig ntaus, lossis khoov, kom ua tau raws li qhov xav tau ntawm cov khoom kawg.
Cov txheej txheem kev kos duab kho vajtse plays lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv kho vajtse, ua rau cov khoom siv hlau ntau lawm thiab ntau thiab tsawg. Los ntawm kev siv cov txheej txheem tsim nyog thiab kev tswj hwm nruj, siab - khoom kho vajtse zoo tuaj yeem tau txais.
