Dab tsi yog cov kauj ruam tseem ceeb hauv cov txheej txheem ua haujlwm ntawm nruab nrab-Frequency Direct Current Spot Welding Machine?

Medium-frequency direct tam sim no qhov chaw vuam tshuab yog dav siv nyob rau hauv ntau yam lag luam rau kev koom tes hlau qhov chaw ua ke. Cov tshuab no ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ncaj ncees thiab ua haujlwm ntev ntawm ntau cov khoom, los ntawm cov khoom siv tsheb mus rau cov khoom siv hauv tsev. Yuav kom nkag siab zoo dua li cas cov tshuab no ua haujlwm, cia peb delve rau hauv cov kauj ruam tseem ceeb hauv lawv cov txheej txheem ua haujlwm.

1. Fais fab mov: Thawj kauj ruam hauv kev ua haujlwm ntawm qhov nruab nrab zaus ncaj qha tam sim no qhov chaw vuam tshuab suav nrog muab nws nrog lub zog ruaj khov. Feem ntau, cov tshuab no yuav tsum muaj qhov ncaj qha tam sim no (DC) lub zog hluav taws xob, uas tuaj yeem muab los ntawm ntau txoj kev, suav nrog transformers thiab rectifiers. Cov khoom siv hluav taws xob yuav tsum tau ua tib zoo calibrated los xyuas kom meej qhov voltage thiab tam sim no theem rau cov txheej txheem vuam.
2. Clamping: Thaum cov khoom siv hluav taws xob raug tsim, cov hlau yuav tsum tau koom nrog yog clamped nyob rau hauv txoj hauj lwm. Qhov no yog ib kauj ruam tseem ceeb, vim tias kev sib raug zoo thiab lub siab yog qhov tseem ceeb rau kev ua tiav qhov muaj zog thiab txhim khu kev qha. Qee lub tshuab siv cov tshuab clamps, thaum lwm tus siv cov tshuab pneumatic lossis hydraulic los tuav cov khoom ua ke.
3. Electrode Sib cuag: Cov kauj ruam tom ntej yog nqa cov vuam electrodes rau hauv kev sib cuag nrog cov hlau qhov chaw yuav tsum tau welded. Cov electrodes feem ntau muaj tooj liab lossis lwm yam khoom siv hluav taws xob thiab tsim los xa cov hluav taws xob tam sim no mus rau cov khoom ua haujlwm. Kev tsim hluav taws xob tsim nyog thiab kev sib raug zoo yog qhov tseem ceeb rau kev ua tiav cov khoom siv vuam zoo.
4. Welding Tam sim no daim ntawv thov: Nrog rau cov electrodes nyob rau hauv qhov chaw, lub vuam tshuab siv lub siab tam sim no, feem ntau yog nyob rau hauv daim ntawv ntawm ib tug ncaj qha tam sim no (DC), rau cov ntsiab lus ntawm cov hlau qhov chaw. Qhov tam sim no tsim cov cua kub hnyav, ua rau cov hlau yaj thiab fuse ua ke. Lub sijhawm thiab kev siv ntawm cov dej ntws tam sim no tau ua tib zoo tswj kom tsim tau ib daim ntawv cog lus muaj zog thiab ruaj khov yam tsis muaj cua sov los yog ua rau cov khoom puas.
5. Cooling thiab Solidification: Tom qab siv cov vuam tam sim no, lub tshuab feem ntau suav nrog lub tshuab ua kom txias kom nrawm rau qhov chaw welded. Qhov no yuav pab kom khov cov hlau molten thiab txo qhov tsim ntawm qhov tsis xws luag los yog qhov chaw tsis muaj zog hauv qhov vuam. Kev ua kom txias zoo yog qhov tseem ceeb rau kev ua tiav cov khoom zoo, cov qauv zoo nkauj.
6. Kev Tswj Xyuas Zoo: Thaum kawg, lub welded sib dhos yog raug rau kev tswj xyuas zoo kom ntseeg tau tias cov vuam ua tau raws li cov qauv teev tseg. Qhov no yuav suav nrog kev tshuaj xyuas qhov muag, kev sim tsis muaj kev puas tsuaj, lossis lwm txoj hauv kev los txheeb xyuas qhov tsis xws luag, tawg, lossis qhov tsis sib xws hauv qhov vuam. Txhua yam teeb meem raug daws los xyuas kom meej tias cov khoom kawg ua tau raws li qhov xav tau zoo thiab kev ua tau zoo.

Hauv kev xaus, qhov nruab nrab zaus ncaj qha tam sim no qhov chaw vuam tshuab ua raws cov kauj ruam tseem ceeb los koom nrog cov khoom hlau zoo. Los ntawm kev tsim kom muaj lub zog ruaj khov rau kev siv cov vuam tam sim no thiab ua cov kev tswj xyuas zoo, txhua kauj ruam ua lub luag haujlwm tseem ceeb hauv kev tsim cov welds muaj zog thiab txhim khu kev qha. Kev nkag siab txog cov txheej txheem kev ua haujlwm no yog qhov tseem ceeb rau cov neeg koom nrog hauv kev tsim hlau thiab kev tsim khoom lag luam.
