Capacitor Discharge (CD) qhov chaw vuam tshuab tau siv dav hauv ntau qhov kev lag luam rau lawv lub peev xwm los xa cov khoom siv tau zoo thiab muaj txiaj ntsig zoo. Cov txheej txheem vuam hauv cov tshuab no suav nrog ntau theem sib txawv ntawm lub sijhawm vuam, txhua qhov ua rau tag nrho qhov zoo thiab kev ncaj ncees ntawm kev sib koom ua ke. Kab lus no tshawb txog cov theem sib txawv ntawm lub sijhawm vuam hauv CD qhov chaw vuam tshuab thiab lawv qhov tseem ceeb hauv kev ua tiav cov txiaj ntsig zoo vuam.
Theem ntawm Vuam Sijhawm:
- Tiv tauj Theem:Nyob rau theem kev sib cuag, cov electrodes ua rau lub cev sib cuag nrog cov workpieces yuav tsum tau welded. Qhov kev sib cuag thawj zaug no tsim ib txoj hauv kev ntawm cov electrodes thiab cov khoom ua haujlwm. Lub sijhawm tiv tauj yog qhov tseem ceeb rau kev ua kom muaj kev sib txuas hluav taws xob zoo ib yam thiab ruaj khov.
- Pre-Welding Phase:Tom qab lub sij hawm sib cuag, lub pre-weld theem pib. Thaum lub sij hawm no, ib tug predetermined tus nqi ntawm lub zog yog them mus rau hauv lub vuam capacitor. Qhov kev tsim lub zog no yog qhov tseem ceeb rau kev ua tiav lub zog txaus rau kev tsim cov weld nugget.
- Vuam Phase:Lub vuam theem yog lub sij hawm thaum lub zog them nyob rau hauv lub capacitor yog tawm los ntawm cov electrodes thiab mus rau hauv lub workpieces. Lub zog siab tso tawm tsim ib qho chaw fusion ntawm cov ntaub ntawv, tsim cov weld nugget. Lub sij hawm ntawm lub vuam theem ncaj qha cuam tshuam rau vuam nkag thiab sib koom ua ke lub zog.
- Tom qab Weld Phase:Tom qab lub vuam theem, muaj ib theem tom qab vuam thaum lub sij hawm lub electrodes nyob rau hauv kev sib cuag nrog lub workpieces kom cov weld nugget solidify thiab txias. Cov theem no ua rau muaj kev txhim kho ntawm kev sib koom ua ke uas muaj zog thiab ruaj khov.
- Theem cua txias:Thaum lub sijhawm tom qab vuam tiav lawm, lub caij txias pib. Thaum lub sij hawm no, cov electrodes yog tag nrho retracted, thiab cov residual tshav kub nyob rau hauv lub weld cheeb tsam dissipates. Kev ua kom txias zoo pab tiv thaiv overheating thiab distortion ntawm welded Cheebtsam.
Lub sijhawm vuam nyob rau hauv Capacitor Discharge qhov chaw vuam tshuab tau muab faib ua ntau theem sib txawv, txhua tus ua lub luag haujlwm tseem ceeb hauv kev ua tiav cov vuam zoo. Kev sib cuag theem tsim kom muaj kev sib txuas ruaj khov, theem ua ntej-weld tsim lub zog, lub vuam theem tsim cov vuam nugget, tom qab vuam theem tso cai rau kev ruaj khov, thiab cov cua txias theem tiv thaiv overheating. Cov neeg tsim khoom thiab cov neeg ua haujlwm yuav tsum ua tib zoo xav txog thiab ua kom zoo rau txhua theem ntawm lub sijhawm kom ntseeg tau tias qhov zoo sib xws ntawm cov vuam zoo, sib koom ua ke, thiab kev ua haujlwm tag nrho. Los ntawm kev nkag siab thiab tswj cov theem no, CD qhov chaw vuam tshuab tuaj yeem tsim cov welds txhim khu kev qha thiab muaj zog thoob plaws ntau yam kev siv.
