Thermal Balance and Heat Distribution in Medium Frequency Inverter Spot Welding Machines

Thermal tshuav nyiaj li cas thiab kev faib hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm thiab kev ua haujlwm zoo ntawm welds tsim los ntawm nruab nrab zaus inverter chaw vuam tshuab.Cov yam tseem ceeb no txiav txim siab qhov hloov pauv tau zoo thiab kev faib tawm ntawm cov cua sov thaum lub sijhawm vuam, thaum kawg cuam tshuam rau lub zog thiab kev ncaj ncees ntawm cov pob qij txha welded.Kab lus no muab cov ntsiab lus ntawm thermal tshuav nyiaj li cas thiab kev faib hluav taws xob hauv nruab nrab zaus inverter qhov chaw vuam tshuab.

1. Thermal Balance in Spot Welding: Thermal balance yog hais txog qhov sib npaug ntawm cov khoom siv hluav taws xob thiab cov cua kub dissipation thaum lub sij hawm vuam.Ua kom tau raws li qhov sib npaug ntawm cov thermal yog qhov tseem ceeb los tswj lub tshav kub cuam tshuam (HAZ) thiab tiv thaiv overheating lossis underheating ntawm lub workpiece.Nws suav nrog kev ua kom zoo dua cov vuam tsis zoo, xws li vuam tam sim no, lub sijhawm, thiab lub zog electrode, kom ntseeg tau tias qhov xav tau cua sov nkag thiab dissipation rau ib daim ntawv thov tshwj xeeb.Kev sib npaug thermal zoo ua rau muaj kev tswj xyuas zoo ntawm cov khoom siv weld thiab txo qhov tshwm sim ntawm qhov tsis xws luag xws li hlawv-los ntawm kev sib xyaw lossis tsis txaus fusion.
2. Thaum tshav kub kub Distribution in Spot Welding: Thaum tshav kub kub faib yog hais txog txoj kev tshav kub dispersed nyob rau hauv lub workpiece thaum lub sij hawm welding.Nws txiav txim siab qhov kub thiab txias qhov profile thiab qhov tshwm sim metallurgical hloov nyob rau hauv weld cheeb tsam.Kev faib hluav taws xob yog cuam tshuam los ntawm ntau yam, suav nrog cov vuam tam sim no, lub zog electrode, workpiece geometry, thiab cov khoom siv.Cov khoom siv hluav taws xob sib txawv yog qhov xav tau kom ua tiav qhov zoo sib xws thiab tsis txhob muaj cua sov hauv cheeb tsam lossis cua sov, uas tuaj yeem ua rau cov qauv tsis muaj zog lossis cov khoom siv vuam.
3. Cov yam ntxwv cuam tshuam rau Thermal Balance thiab Heat Distribution: Ob peb yam cuam tshuam rau qhov sib npaug thermal thiab kev faib hluav taws xob hauv qhov chaw vuam tshuab:
   • Welding parameters: Kev xaiv thiab hloov kho ntawm vuam tam sim no, lub sijhawm, thiab electrode quab yuam cuam tshuam rau cov cua sov nkag thiab xa tawm.
   • Electrode tsim thiab cov khoom siv: Kev tsim hluav taws xob tsim nyog thiab kev xaiv cov khoom ua rau muaj txiaj ntsig zoo rau kev hloov hluav taws xob thiab kev faib tawm thaum vuam.
   • Cov khoom siv ntawm cov khoom ua haujlwm: Cov thermal conductivity, melting point, thiab tshav kub muaj peev xwm ntawm cov khoom siv ua haujlwm cuam tshuam rau cov cua sov dissipation thiab kev faib tawm.
   • Workpiece Geometry: Cov duab, tuab, thiab qhov chaw ntawm lub workpiece cuam tshuam cov cua sov ntws thiab kev faib tawm.
4. Qhov tseem ceeb ntawm Kev Ua Tau Zoo Tshaj Plaws Thermal Balance thiab Heat Distribution: Ua kom tau txais qhov zoo tshaj plaws thermal tshuav nyiaj li cas thiab kev faib hluav taws xob muaj ntau yam txiaj ntsig:
   • Ua tib zoo weld zoo: Kev faib hluav taws xob kom zoo ua kom zoo ib yam fusion thiab metallurgical zog, ua rau txhim khu kev qha thiab rov ua dua welds.
   • Txo kev cuam tshuam thiab kev ntxhov siab: Kev sib npaug ntawm cov cua sov kom txo qis kev cuam tshuam thiab kev ntxhov siab nyob hauv cov khoom siv welded.
   • Txhim kho kev sib koom ua ke muaj zog: Kev faib hluav taws xob zoo tshaj plaws txhawb nqa cov qauv zoo li qub thiab cov khoom siv kho tshuab, ua rau cov pob qij txha muaj zog dua.

Thermal tshuav nyiaj li cas thiab kev faib hluav taws xob yog qhov tseem ceeb ntawm nruab nrab zaus inverter qhov chaw vuam tshuab.Los ntawm kev nkag siab txog cov xwm txheej cuam tshuam rau qhov sib npaug ntawm qhov sib npaug ntawm cov cua sov thiab kev faib hluav taws xob thiab siv cov txheej txheem vuam tsim nyog thiab cov txheej txheem, cov neeg ua haujlwm tuaj yeem ua tiav cov vuam zoo ib yam thiab zoo.Kev mob siab rau thermal tshuav nyiaj li cas thiab kev faib hluav taws xob ua rau muaj txiaj ntsig zoo thiab kev ntseeg siab ntawm cov txheej txheem vuam, ua kom muaj zog thiab ruaj khov welded pob qij txha hauv ntau daim ntawv thov kev lag luam.
