Kodi Panopa ndi Voltage Zimakhudza Kuchita Bwino kwa Resistance Spot Welding?

Resistance spot welding ndi njira yolumikizirana yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, makamaka popanga magalimoto ndi ndege. Njirayi imaphatikizapo kugwiritsa ntchito magetsi ndi kukakamiza kuti apange zomangira zolimba pakati pa mapepala azitsulo kapena zigawo zikuluzikulu. Chimodzi mwazinthu zofunika kwambiri zomwe nthawi zambiri zimadzutsa mafunso ndi gawo lamagetsi apano ndi magetsi pozindikira mtundu ndi mphamvu ya ma welds. M'nkhaniyi, tiwona momwe makonzedwe apano ndi ma voliyumu amagwirira ntchito pa resistance spot welding.

Kumvetsetsa Resistance Spot Welding

Musanalowe mu mphamvu ya magetsi ndi magetsi, ndikofunikira kumvetsetsa zoyambira za resistance spot welding. Pochita izi, zinthu ziwiri zachitsulo zimakhudzidwa ndikukhudzidwa ndi magetsi apamwamba. Pakalipano izi zimayenda muzitsulo ndikupanga kutentha chifukwa cha kukana kwake. Kutentha kumasungunula kachigawo kakang'ono kachitsulo, kupanga nugget yosungunuka yomwe imazizira ndi kulimba kupanga weld.

Udindo wa Panopa

Zomwe zilipo panopa pakuwotcherera kwa malo otsutsa zimagwira ntchito yofunika kwambiri pozindikira mtundu wa weld. Zimakhudza kutentha kwa kutentha, kukula kwa nugget, ndi mphamvu zonse za mgwirizano. Umu ndi momwe:

1. Kuwotcha:Miyezo yapamwamba yamakono imayambitsa kutentha kwachangu. Izi zitha kukhala zopindulitsa pazinthu zopyapyala chifukwa zimachepetsa kutentha kwapang'onopang'ono ndikupangitsa kuti pakhale malo ochepa omwe amakhudzidwa ndi kutentha. Komabe, chifukwa cha zinthu zokhuthala, kuchuluka kwa madzi kungayambitse kuwotcha kapena kuwaza.
2. Kukula kwa Nugget:Panopa zimakhudza kukula kwa nugget yosungunuka yomwe imapangidwa panthawi yowotcherera. Miyezo yapamwamba yamakono imakonda kupanga ma nuggets akuluakulu. Kukula kwa nugget ndikofunikira chifukwa kumakhudza mwachindunji mphamvu ya olowa. Kusakwanira kwamagetsi kumatha kupangitsa kuti tinthu tating'ono ting'onoting'ono, tisokoneze kukhulupirika kwa weld.
3. Mphamvu ya Bond:Ubwino wa weld umagwirizanitsidwa kwambiri ndi zamakono. Zosinthidwa bwino zomwe zikuchitika pano zimatsimikizira kuti weld yolimba komanso yolimba. Kupatuka pazigawo zomwe zikuyembekezeredwa kungayambitse zomangira zofooka ndikuchepetsa kukhulupirika kwadongosolo.

Udindo wa Voltage

Voltage, molumikizana ndi yapano, imakhala ndi gawo lothandizira pakuwotcherera malo:

1. Chiyambi cha Arc:Voltage ndi yomwe imayambitsa arc pakati pa electrode ndi workpiece. Iyenera kukhala yokwanira kuthana ndi kukana kwa electrode-workpiece interface. Magetsi otsika angapangitse ma arcs osakhazikika komanso kutsika kwa weld.
2. Kuwongolera kwa Weld Pool:Voltage imakhudzanso mawonekedwe ndi kukhazikika kwa dziwe la weld. Zimathandizira kuwongolera kayendedwe kachitsulo chosungunuka ndikuwonetsetsa kugawa kofanana, kuteteza kusokonezeka kwa mikanda yowotcherera.

Kukhathamiritsa Kwapano ndi Voltage

Kuti mukwaniritse ma welds amtundu wapamwamba kwambiri, ndikofunikira kukhathamiritsa zonse zomwe zikuchitika komanso ma voltage. Izi zimaphatikizapo kuganizira zinthu monga makulidwe azinthu, mtundu wachitsulo, ndi kapangidwe ka electrode. Opanga nthawi zambiri amapereka malangizo owotcherera ndi malingaliro pazinthu zenizeni ndi ntchito.

Pomaliza, pompopompo ndi magetsi ndizofunikira kwambiri pakuwotcherera kwa malo. Kusintha moyenera zoikamo izi ndikofunikira kuti mupange ma weld odalirika komanso olimba. Kupatuka pazikhalidwe zomwe amalangizidwa kungayambitse zolakwika, kuchepa kwamphamvu kwa ma bond, komanso kulephera kwadongosolo. Chifukwa chake, kumvetsetsa ubale womwe ulipo pakati pa zomwe zikuchitika pano, ma voliyumu, ndi zowotcherera ndikofunikira pakuwonetsetsa kuti njira zowotcherera zikuyenda bwino m'mafakitale osiyanasiyana.
