Yog tias koj tshiab rau kev tiv thaiv vuam lossis nrhiav kev nkag siab zoo dua ntawm nws, ces koj yuav tsum tau nyeem cov lus no kom zoo.Qhov tsab xov xwm no yuav coj koj mus tob rau hauv lub ntiaj teb no ntawm kuj welding.Txawm hais tias koj yog tus pib los yog tab tom nrhiav kom nthuav koj txoj kev paub, kab lus no yuav muab cov kev nkag siab zoo rau koj.
Resistance Welding yog dab tsi?
Resistance vuam yog ib qho kev kub ceev, kev lag luam hlau koom nrog txoj kev.Cov txheej txheem vuam no yog tsim rau cov pob qij txha, pob qij txha, lossis cov pob qij txha uas tsis tas yuav tsum muaj huab cua nruj, nrog cov thicknesses tsawg dua 6 hli rau cov ntawv nyias nyias.Tau kawg, nws tseem tuaj yeem txuas cov hlau ua haujlwm hnyav dua thiab loj dua, tab sis nws qhov kev ua tau zoo tag nrho yuav tsis zoo li qee yam kev siv vuam.
Txhais thiab Cov Ntsiab Cai
Kuj weldingyog ib txoj kev uas cov workpieces yuav tsum tau muab tso rau ntawm ob electrodes.Los ntawm kev hla tam sim no los ntawm cov khoom ua haujlwm thiab cov ntsiab lus sib cuag, cov cua sov ua haujlwm tshwm sim, ua kom muaj cua sov ntawm qhov sib txuas ntawm cov khoom ua haujlwm.Cov cua sov hauv cheeb tsam no ua rau thaj chaw yaj lossis ua kom muaj zog, thaum lub zog los ntawm ob lub electrodes bonds cov hlau ua ke.
Thaum tam sim no ntws los ntawm ib tug conductor, nws generates tshav kub vim tsis kam.Qhov siab dua qhov kev tiv thaiv thaum qhov tam sim no tsis tu ncua, qhov kub ntau yog tsim.Ntawm qhov chaw uas cov hlau nyob rau hauv kev sib cuag, qhov kev tiv thaiv yog ntau dua nyob rau hauv cov hlau nws tus kheej.Yog li ntawd, thaum ib tug loj tam sim no dhau los ntawm kev sib cuag ntawm cov hlau thiab cov electrode, cov hlau sai sai heats li vim lub loj heev tshav kub.Nyob rau lub sijhawm no, cov hlau ua tau zoo heev, thiab nrog kev siv siab, ob daim hlau ruaj khov ua ke.
Resistance Welding Txoj Cai Ua Haujlwm
Lub hauv paus ntsiab lus ntawm kev tiv thaiv qhov chaw vuam thiab tsim cov pob qij txha yog qhia hauv daim duab 1-1.Hlau A thiab hlau B yog muab tso rau ntawm ob lub electrodes, thiab lub siab yog siv rau electrodes.Lub zog tam sim no dhau ntawm ob lub electrodes los ntawm kev hloov pauv ntawm cov welder tsis kam.Qhov chaw sib cuag ntawm lub workpieces tsim ib qho kev sib cuag ntawm lub cev, uas maj mam nthuav tawm raws li qhov tam sim no heats nws.Yas deformation thiab kub tsis tu ncua ua kom cov atoms ntawm qhov chaw sib cuag, ua rau tsim cov molten core.Lub molten core hlob nyob rau hauv daim ntawv ntawm columnar crystals, thawb tawm lub siab dua alloy concentration Cheebtsam ntawm ib leeg.Thaum cov electrodes ntawm lub welder txav deb ntawm cov hlau nto, thiab cov hlau txias, cov workpieces yog welded ua ke, tsim kom muaj ib tug muaj zog hlau daim ntawv cog lus.Qhov kev sib koom ua ke ploj mus, tawm hauv qab lub weld nugget.

Cov yam ntxwv cuam tshuam rau kev tiv thaiv vuam
Kuj weldingyog ib txoj kev vuam uas siv hluav taws xob tam sim no los ua kom muaj cua sov los koom nrog cov khoom siv hlau.Raws li tau hais ua ntej, lub hauv paus ntsiab lus ntawm kev siv vuam vuam feem ntau yog los ntawm Joule txoj cai ntawm kev siv cua sov, qhov chaw ntawm vuam cov cua sov yog feem ntau txiav txim siab los ntawm cov tsis xws li tam sim no, tsis kam, thiab vuam lub sij hawm.Nws tuaj yeem hais tau los ntawm cov qauv hauv qab no:
Q = I² Rt
Lub ntsiab lus ntawm txhua qhov welding parameter:
Q — Thaum tshav kub kub (J)
I - Vuam tam sim no (A)
R - Kuj (Ω)
t - Vuam lub sij hawm (s)
Vuam tam sim no
Cov tam sim no muaj kev cuam tshuam tseem ceeb rau cov cua sov uas tsim thaum lub sij hawm vuam, raws li qhia hauv cov qauv.Tus nqi square ntawm tam sim no cuam tshuam cov cua sov, txhais tau hais tias qhov siab dua tam sim no, qhov kub yuav nce sai dua.Yog li ntawd, thaum kho vuam tsis ua ntej welding, nws yog ib qho tseem ceeb kom teem lub tam sim no tsim nyog.Yog tias qhov vuam tam sim no me dhau, qhov vuam yuav tsis yaj, thiab tsis muaj fusion core yuav tsim.Yog tias qhov tam sim no loj dhau lawm, fusion core yuav loj hlob sai, ua rau muaj kev sib tsoo ntau dhau thaum vuam thiab ua rau cov electrodes puas.
Vuam tam sim no feem ntau muab faib ua alternating tam sim no (AC) thiab ncaj qha tam sim no (DC), raws li qhia hauv daim duab hauv qab no.Covchaw vuam tshuabpeb siv kuj tau muab faib mus rau hauv ncaj qha tam sim no qhov chaw vuam tshuab thiab alternating tam sim no qhov chaw vuam tshuab.Lub tshuab vuam ncaj nraim tam sim no siv peb-theem fais fab mov, ua kom muaj zog sib npaug, thiab tuaj yeem ua tiav vuam zaus ntau dua 1000 Hz, ua rau muaj qhov raug vuam siab.Lawv kuj muaj qhov zoo ntawm qhov xav tau ntawm cov hluav taws xob tsawg los ntawm daim phiaj hluav taws xob, ua rau cov khoom siv hluav taws xob txuag hluav taws xob nce nrov ntawm cov tuam txhab tsim khoom lag luam.Alternating tam sim no qhov chaw vuam tshuab muaj ib theem 50Hz tso zis, siab nruam load peev xwm, thiab siab xav tau rau daim phiaj fais fab.Tsis tas li ntawd, lawv muaj lub zog vuam qis, xav tau lub sijhawm vuam ntev.
Tiv tauj Resistance
Los ntawm cov mis, nws yog ib qho yooj yim kom pom tias tsis kam yog ncaj qha proportional rau lub tshav kub generated.Qhov siab dua qhov tsis kam, qhov ntau dua cov cua sov tsim thaum lub sij hawm vuam.Tsis kam yog muab faib thoob plaws ntau qhov chaw ntawm electrode thiab workpiece.Thaum lub sij hawm vuam, qhov siab tshaj plaws kuj tshwm sim ntawm qhov chaw sib cuag ntawm lub workpiece, uas ua rau lub siab tshaj plaws kub tiam.Tom ntej no yog qhov tsis kam ntawm qhov chaw sib cuag ntawm lub workpiece thiab electrode.Txawm li cas los xij, txij li cov electrode yog dej-txias thiab txias sai sai, qhov kub thiab txias yuav txo qis.Ntawm qhov tod tes, kev sib cuag ntawm cov khoom ua haujlwm, txawm tias nws ploj mus, muaj cov cua sov tsis zoo, ua rau muaj qhov kub thiab txias.Yog li ntawd, tsuas yog ib cheeb tsam me me ntawm cov workpieces tuaj yeem ncav cuag qhov kub thiab txias tsim nyog los tsim cov fusion core thiab weld ua ke.
Tsis tas li ntawd, kub thiab electrode siab cuam tshuam rau qhov tsis kam.Raws li qhov kub thiab txias, cov hlau yield zog txo qis, ua rau thaj chaw sib cuag ntawm cov khoom ua haujlwm thiab nruab nrab ntawm cov khoom ua haujlwm thiab cov electrode, uas ua rau tsis muaj zog.Ua kom cov electrode siab ua rau lub workpiece nto smoother, ua kom cov cheeb tsam sib cuag thiab txo qhov tsis kam.Raws li qhov tshwm sim, muaj qhov tshwm sim uas, thaum lub sij hawm vuam ntawm cov ntaub ntawv raug, qhov kev tiv thaiv nce sai tom qab lub hwj chim, thiab thaum lub hwj chim raug kaw thiab cov ntaub ntawv fusion core, qhov kev tiv thaiv pib txo.
Lub sijhawm vuam
Lub sijhawm vuam ntev dua, qhov siab dua qhov kub tsim.Hauv cov qauv no, tam sim no thiab lub sijhawm tuaj yeem ua tiav ib leeg.Thaum koj xav tau ib qho kev sib txuas uas muaj zog, koj tuaj yeem teeb lub siab tam sim no rau lub sijhawm luv luv los tsim kom muaj cua sov sai thiab tsim cov fusion core kom tiav qhov vuam.Xwb, koj tuaj yeem teem caij qis rau lub sijhawm ntev, tab sis muaj qhov txwv rau txoj hauv kev no.Yog tias lub sijhawm teem sijhawm ntev dhau lawm, nws tuaj yeem ua rau tawg ntau dhau thiab yuav ua rau cov electrode lo.Txawm nws yog tam sim no lossis lub sijhawm, muaj kev txwv.Thaum teeb tsa qhov ntsuas, koj yuav tsum xav txog cov khoom siv thiab thickness ntawm lub workpiece, nrog rau lub zog ntawm lub vuam tshuab.
Khoom Khoom
Cov khoom siv ntawm lub workpiece feem ntau cuam tshuam rau nws qhov kev tiv thaiv, uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov cua sov.Thaum welding stainless hlau, uas muaj kev tiv thaiv siab thiab tsis zoo thermal conductivity, nws yooj yim dua los tsim kom sov tab sis nyuaj rau dissipate nws, yog li me me tam sim no xav tau.Thaum vuam aluminium alloys uas tsis tshua muaj kev tiv thaiv thiab zoo thermal conductivity, nws yog ib qho nyuaj rau tsim kom sov tab sis yooj yim rau dissipate nws, yog li yuav tsum tau loj tam sim no.Cov hlau zoo li cov nyiaj thiab tooj liab muaj cov thermal conductivity thiab tsis tshua muaj zog, yog li txawm tias muaj cov dej ntws siab, lawv tsis tsim kom muaj cua sov ntau tab sis tuaj yeem ua rau nws tawm mus.Yog li ntawd, cov hlau no tsis haum rau kev siv vuam, tab sis tuaj yeem siv los ua cov khoom siv electrode.
Electrode Tsim thiab Geometry
