Chifukwa Chiyani Makina Owotcherera A Resistance Spot Amamamatira Akamawotchera Mbale Zagalasi?

Resistance spot kuwotcherera ndi njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana polumikiza zitsulo pamodzi. Komabe, pogwira ntchito ndi mbale zokhala ndi malata, owotcherera nthawi zambiri amakumana ndi vuto lachilendo - makina owotcherera amatha kumamatira. M'nkhaniyi, tipenda zifukwa zomwe zachititsa kuti izi zitheke ndikufufuza njira zothetsera vutoli.

Kumvetsa Vutoli

Kuwotcherera kwa Resistance spot kumaphatikizapo kudutsa magetsi okwera kwambiri kudzera muzitsulo ziwiri, kupanga malo osungunuka omwe amawagwirizanitsa pamodzi. Pamene kuwotcherera mbale kanasonkhezereka, wosanjikiza akunja imakhala nthaka, amene ali otsika kusungunuka mfundo kuposa chitsulo. Zinc wosanjikiza uyu amatha kusungunuka chitsulo chisanayambe, zomwe zimatsogolera ku ma electrode owotcherera kumamatira ku mbale.

Zomwe Zimayambitsa Kumamatira mu Wowotcherera Mbale Wagalasi

1. Zinc vaporization:Panthawi yowotcherera, kutentha kwakukulu kumapangitsa kuti nthaka isanjike. Mpweya uwu ukhoza kuwuka ndi kukhazikika pa ma elekitirodi owotcherera. Zotsatira zake, maelekitirodi amakutidwa ndi zinc, zomwe zimatsogolera kumamatira ndi workpiece.
2. Kuwonongeka kwa Electrode:Kupaka kwa zinki kumatha kuwononganso ma elekitirodi owotcherera, kumachepetsa kuwongolera kwawo ndikupangitsa kuti amamatire ku mbale.
3. Kupaka kwa Zinc Osafanana:Nthawi zina, mbale zokhala ndi malata zimatha kukhala ndi zokutira za zinki zosagwirizana. Kusagwirizana kumeneku kungayambitse kusiyanasiyana kwa njira yowotcherera ndikuwonjezera mwayi womamatira.

Njira Zopewera Kumamatira

1. Kukonzekera kwa Electrode:Nthawi zonse yeretsani ndikusunga ma elekitirodi owotcherera kuti mupewe kuchuluka kwa zinc. Zovala zapadera zotsutsana ndi ndodo kapena zovala zilipo kuti muchepetse kumamatira.
2. Zowotcherera Zoyenera:Sinthani zowotcherera, monga zamakono, nthawi, ndi kukakamiza, kuti muchepetse kutentha. Izi zitha kuthandiza kuwongolera kutulutsa kwa zinc ndikuchepetsa kumamatira.
3. Kugwiritsa Ntchito Copper Alloys:Ganizirani kugwiritsa ntchito ma electrode a copper alloy welding. Mkuwa uli ndi malo osungunuka kwambiri kuposa zinki ndipo sungathe kumamatira ku chogwirira ntchito.
4. Kukonzekera Pamwamba:Onetsetsani kuti zowotcherera ndi zoyera komanso zopanda zowononga. Kukonzekera bwino pamwamba kungachepetse chiopsezo chomamatira.
5. Pewani Zowotcherera Zophatikizana:Chepetsani ma welds omwe amaphatikizika, chifukwa amatha kugwira zinki zosungunuka pakati pa mbale, ndikuwonjezera mwayi womamatira.
6. Mpweya wabwino:Gwiritsani ntchito mpweya wabwino kuti muchotse utsi wa zinki pamalo owotcherera, kuteteza kuipitsidwa ndi ma elekitirodi.

Nkhani ya makina owotcherera omwe amamatira powotcherera mbale zitha kukhala chifukwa cha mawonekedwe apadera a zinki komanso zovuta zomwe amapereka pakuwotcherera. Pomvetsetsa zomwe zimayambitsa ndikugwiritsa ntchito njira zomwe zaperekedwa, ma weld amatha kuwongolera luso lawo ndikuchepetsa kupezeka kwa kumamatira, kuwonetsetsa kuti ma welds apamwamba kwambiri pama mbale awo amalatisi.
