Casting yog dab tsi?
Kev ua yeeb yamyog ib qho txheej txheem uas cov hlau raug yaj ua kua, nchuav rau hauv pwm, thiab cia kom khov ua ib daim duab tshwj xeeb. Tom qab txias, pwm raug tshem tawm, thiab cov khoom kawg tuaj yeem ua tiav lossis ua tiav ntxiv.
Muaj ntau hom txheej txheem casting, suav nrog:
-
Kev xuab zeb casting
-
Kev nqis peev casting (lost-wax)
-
Tuag casting
-
Kev sib tsoo centrifugal
Kev tsim khoom yog qhov zoo tagnrho rau kev tsim khoomcov qauv geometry nyuajthiabntau ntauntawm cov khoom nrogtsawg dua kev ua haujlwm.
Dab tsi yog Forging?
Kev ntaus nrigyog ib txoj kev tsim khoom uas muaj feem cuam tshuam nrogua cov hlau siv cov zog compressive, feem ntau nrog rauj lossis nias. Cov hlau feem ntau yogcua sov tab sis tseem khov khothiab siv cov khoom siv los ua kom tau raws li qhov xav tau, thiab deformation yuav tsum tau ua.
Cov hom kev forging muaj xws li:
-
Qhib-tuag forging
-
Kev tuag kaw forging
-
Kev ua kom txias
-
Kev ua kom sov sov
-
Nplhaib dov
Forging ua rau kom muaj zoglub zog kho tshuabthiabkev ruaj khov ntawm cov qauvntawm cov khoom siv hlau los ntawm kev sib dhos cov nplej ntws hauv kev coj ntawm kev ntxhov siab.
Qhov Txawv Tseem Ceeb Ntawm Kev Casting thiab Forging
