Mau oyamba a Spot Welding galvanized Sheets with Medium Frequency Inverter Spot Welding Machines

Spot kuwotcherera ndi njira yomwe imagwiritsidwa ntchito kwambiri kujowina mapepala opangira malata m'mafakitale osiyanasiyana. Ma sheet a galvanized, omwe amadziwikanso kuti zitsulo zokhala ndi malata kapena zitsulo zokutira zinki, amapereka kukana kwa dzimbiri komanso kulimba. M'nkhaniyi, tiona ndondomeko kuwotcherera malo kanasonkhezereka mapepala ntchito sing'anga pafupipafupi inverter malo kuwotcherera makina, kuunikila mfundo zofunika ndi njira nawo.

1. Kumvetsetsa Mapepala Amalata: Mapepala agalasi ndi zitsulo zachitsulo zomwe zimakutidwa ndi zinki kuti zitetezeke ku dzimbiri. Kupaka kwa zinki kumapereka nsembe yoperekera nsembe yomwe imalepheretsa zitsulo zapansi kuti zisagwirizane ndi malo ozungulira, motero kuchepetsa chiopsezo cha kupanga dzimbiri. Komabe, kukhalapo kwa zokutira za zinki kumabweretsa zovuta zina pakuwotcherera malo, zomwe ziyenera kuthetsedwa kuti zitheke zowotcherera zodalirika komanso zapamwamba.
2. Kusankha kwa Electrode: Mukawotcherera ma sheet owala, kusankha ma elekitirodi ndikofunikira. Kulingalira kwapadera kuyenera kuperekedwa kwa zinthu za elekitirodi ndi zokutira kuti zitsimikizire kuti zimagwirizana ndi malo opangira malata. Ndibwino kuti mugwiritse ntchito maelekitirodi opangidwa kuchokera ku zipangizo monga ma aloyi amkuwa kapena zipangizo zotsutsana ndi zomata kuti muchepetse chiopsezo cha zinc adhesion pa electrode surfaces.
3. Kuyeretsa ndi Kukonzekera Pamwamba: Kuyeretsa bwino ndi kukonza pamwamba ndikofunikira musanawotchere mapepala a malata. Kupaka kwa zinki pamapepala kumatha kukhala ndi zonyansa, monga mafuta, dothi, kapena ma oxides, zomwe zingalepheretse kuwotcherera ndikusokoneza mtundu wa weld. Kuyeretsa bwino pogwiritsa ntchito zosungunulira zoyenera kapena zochotsera mafuta ndikofunikira kuti muchotse zowononga zilizonse ndikuwonetsetsa kuti pamakhala malo oyera owotcherera.
4. Zowotcherera Zowotcherera: Zowotcherera za Spot zimagwira ntchito yofunika kwambiri pakukwaniritsa zowotcherera zodalirika pamapepala opaka malata. Mphamvu yowotcherera, nthawi yowotcherera, ndi mphamvu ya electrode ziyenera kusinthidwa mosamala kuti zitsimikizire kupezeka kwa zokutira za zinki. Kuwotcherera kwapamwamba komanso nthawi yayitali yowotcherera nthawi zambiri kumafunika kuti pakhale kuphatikizika koyenera pakati pa mapepala opaka malata. Mphamvu ya elekitirodi iyeneranso kukhazikitsidwa moyenera kuti ikhazikitse kulumikizana koyenera ndikulimbikitsa kutentha kokwanira panthawi yowotcherera.
5. Chithandizo cha Post-Weld : Pambuyo kuwotcherera mapepala a malata, ndikofunikira kuthana ndi zovuta zomwe zingagwirizane ndi kuwotcherera. Chodetsa nkhaŵa chodziwika bwino ndi mapangidwe a zinc spatter, omwe amatha kuchitika chifukwa cha vaporization ya ❖ kuyanika kwa nthaka panthawi yowotcherera. Kuti muchepetse izi, chithandizo chamankhwala pambuyo pa weld monga kuchotsa zinc spatter kapena kuyeretsa pamwamba kungakhale kofunikira kuti mukwaniritse zowotcherera zoyera komanso zowoneka bwino.

Malo kuwotcherera mapepala kanasonkhezereka ntchito sing'anga pafupipafupi inverter malo kuwotcherera makina amapereka njira yodalirika ndi kothandiza kujowina zipangizozi. Poganizira zinthu monga kusankha ma elekitirodi, kuyeretsa koyenera ndi kukonzekera pamwamba, zowotcherera zowotcherera, ndi chithandizo chapambuyo pa kuwotcherera, opanga amatha kupeza ma welds apamwamba kwambiri pamapepala amalatisi. Izi zimathandizira kupanga zida zolimba komanso zosagwira dzimbiri, kupanga makina owotcherera ma frequency a frequency inverter spot kukhala chida chamtengo wapatali m'mafakitale omwe amagwira ntchito ndi zitsulo zamagalasi.
