Resistance chaw welding yog ib txoj kev siv dav hauv kev tsim khoom thiab kev tsim kho, thiab ib qho ntawm nws cov khoom tseem ceeb yog qhov hloov pauv hauv lub tshuab vuam.Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv intricacies ntawm qhov chaw welding tshuab transformers, tshawb txog lawv txoj haujlwm, tsim, thiab cov kev xav tseem ceeb.
Resistance spot welding yog ib qho txheej txheem siv los koom nrog cov khoom siv hlau los ntawm kev tsim cov chaw welds.Nws tso siab rau kev siv hluav taws xob tam sim no dhau los ntawm cov khoom hlau los ua kom muaj cua sov, uas ua rau cov ntaub ntawv sib xyaw ua ke.Lub transformer plays lub luag haujlwm tseem ceeb hauv cov txheej txheem no, vim nws yog lub luag haujlwm muab qhov tsim nyog voltage thiab tam sim no los tsim cov welds txhim khu kev qha.
Transformer muaj nuj nqi
Lub luag haujlwm tseem ceeb ntawm lub transformer nyob rau hauv ib qho chaw tsis kam vuam tshuab yog txhawm rau txo qis cov khoom siv hluav taws xob mus rau qib tsim nyog rau vuam.Nws feem ntau hloov siab-voltage, tsis tshua muaj hluav taws xob tam sim no los ntawm lub zog hluav taws xob mus rau qhov tsis tshua muaj hluav taws xob, lub zog siab tam sim no haum rau vuam.
Tsim thiab Tsim
Resistance chaw vuam tshuab transformers feem ntau yog tsim los siv cov khoom zoo sib nqus xws li laminated hlau cores lossis ferrite cores.Cov ntaub ntawv no raug xaiv rau lawv lub peev xwm ua tau zoo thiab hloov hluav taws xob hluav taws xob thaum txo qis.
Lub transformer muaj cov thawj thiab theem nrab windings.Thawj winding yog txuas nrog lub hwj chim qhov chaw, thaum lub thib ob winding txuas nrog lub vuam electrodes.Thaum thawj winding yog energized, nws induces ib tug tam sim no nyob rau hauv lub thib ob winding, uas yog siv los tsim cov welding tam sim no.
Cov ntsiab lus tseem ceeb
- Hloov Ratio: Qhov sib piv ntawm thawj thiab theem nrab windings txiav txim siab qhov hloov pauv voltage.Ib qho kev hloov pauv siab dua nce qib qis dua qhov voltage thiab nce qhov tam sim no, thaum tus nqi qis dua ua qhov sib txawv.Kev xaiv kom zoo ntawm qhov sib piv yog qhov tseem ceeb heev kom ua tiav qhov xav tau weld zoo.
- Txias: Transformers tsim hluav taws xob thaum lub sijhawm ua haujlwm, thiab cov txheej txheem ua kom txias yog qhov tseem ceeb los tiv thaiv kev kub dhau.Qhov no tuaj yeem suav nrog kev siv cov kiv cua txias lossis roj-txias tshuab kom tswj tau qhov kub thiab txias.
- Copper Losses: Transformers muaj tooj liab windings, uas muaj inherent kuj.Qhov kev tiv thaiv no ua rau tooj liab poob rau hauv daim ntawv ntawm tshav kub.Kev loj hlob zoo ntawm lub transformer thiab kev siv cov khoom siv hluav taws xob zoo tuaj yeem txo qhov kev poob no.
- Lub luag hauj lwm Cycle: Lub voj voog lub luag haujlwm ntawm lub tshuab vuam txiav txim siab ntev npaum li cas nws tuaj yeem ua haujlwm tsis tu ncua ua ntej yuav tsum muaj lub sijhawm txias.Transformers yuav tsum tau tsim los tswj lub voj voog uas yuav tsum tau ua kom tsis txhob overheating thiab puas.
- Kev tu: Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm lub tshuab hloov pauv yog qhov tseem ceeb kom ntseeg tau tias nws lub neej ntev thiab kev ua haujlwm zoo ib yam.Qhov no suav nrog kev txheeb xyuas cov kev sib txuas xoob xoob, cov kab hluav taws xob puas, thiab ua kom txias kom zoo.
Nyob rau hauv xaus, lub transformer nyob rau hauv ib tug kuj qhov chaw vuam tshuab yog ib qho tseem ceeb tivthaiv uas ua rau lub vuam txheej txheem los ntawm muab cov tsim nyog hluav taws xob transformation.Nkag siab txog nws txoj haujlwm, kev xav txog kev tsim, thiab kev saib xyuas yog qhov tseem ceeb rau kev ua tiav cov khoom siv vuam zoo thiab ua kom lub neej ntev ntawm cov khoom siv vuam.
