Mapangidwe a Weld Spots mu Medium-Frequency Inverter Spot Welding

Mawanga a weld amatenga gawo lofunikira pakuwotcherera kwa malo apakati pafupipafupi, kupereka zolumikizira zolimba komanso zodalirika pakati pa zitsulo ziwiri. Kumvetsetsa njira yopangira ma weld spot mapangidwe ndikofunikira pakukhathamiritsa magawo owotcherera, kuwonetsetsa kuti ma welds abwino, ndi kukwaniritsa zomwe amafunidwa amakina. M'nkhaniyi, ife amafufuza mu limagwirira kumbuyo mapangidwe kuwotcherera mawanga sing'anga-pafupipafupi inverter malo kuwotcherera.

1. Kulumikizana ndi Kuponderezana: Gawo loyamba pakupanga ma weld spot ndikukhazikitsa kulumikizana ndi kupanikizana pakati pa nsonga za elekitirodi ndi chogwirira ntchito. Pamene maelekitirodi akuyandikira pamwamba pa workpiece, kukakamiza kumagwiritsidwa ntchito kuti apange kukhudzana kolimba. Kuponderezana kumatsimikizira kukhudzana kwapamtima ndikuchotsa mipata iliyonse kapena matumba a mpweya omwe angasokoneze njira yowotcherera.
2. Kutentha kwa Resistance: Ma electrode akakhazikitsa kukhudzana, mphamvu yamagetsi imadutsa pa workpiece, kutulutsa kutentha kwamphamvu. Kuchulukana kwamakono pa malo okhudzana kumayambitsa kutentha kwapadera chifukwa cha kukana kwa magetsi kwa workpiece. Kutentha kwakukulu kumeneku kumakweza kutentha pamalo olumikizana, zomwe zimapangitsa kuti zitsulo zifewetse ndipo pamapeto pake zimafika posungunuka.
3. Kusungunula Chitsulo ndi Kumangirira: Pamene kutentha kumakwera, chitsulo pa malo okhudzana ndikuyamba kusungunuka. Kutentha kumasamutsidwa kuchokera ku workpiece kupita ku nsonga za electrode, zomwe zimapangitsa kusungunuka kwapadera kwa workpiece ndi electrode material. Chitsulo chosungunuka chimapanga dziwe pamalo olumikizana, ndikupanga gawo lamadzimadzi.
4. Kulimbitsa ndi Kumangirira kwa Dziko Lokhazikika: Dziwe lachitsulo losungunuka likapangidwa, limayamba kulimba. Pamene kutentha kumatha, chitsulo chamadzimadzi chimazizira ndi kukhazikika, ndikubwerera ku malo ake olimba. Panthawi yolimba iyi, kufalikira kwa atomiki kumachitika, kulola maatomu a chogwirira ntchito ndi ma elekitirodi kuti asakanike ndikupanga zomangira zazitsulo.
5. Mapangidwe a Weld Spot: Kulimba kwa chitsulo chosungunuka kumapangitsa kuti pakhale malo olimba. Malo a weld ndi gawo lophatikizidwa pomwe zida zogwirira ntchito ndi ma elekitirodi zidalumikizana, ndikupanga mgwirizano wolimba komanso wokhazikika. Kukula ndi mawonekedwe a weld malo zimatengera zinthu zosiyanasiyana monga kuwotcherera magawo, ma elekitirodi kapangidwe, ndi katundu katundu.
6. Kuziziritsa ndi Kulimbitsa Pambuyo pa Weld: Pambuyo popanga weld malo, kuzizira kumapitilira. Kutentha kumachoka pamalo owotcherera kumadera ozungulira, ndipo chitsulo chosungunuka chimalimba kotheratu. Izi kuzirala ndi kulimba gawo n'kofunika kuti akwaniritse ankafuna zitsulo katundu ndi kuonetsetsa kukhulupirika kwa weld olowa.

Mapangidwe a weld mawanga mu sing'anga-kawirikawiri inverter malo kuwotcherera ndi ndondomeko zovuta zokhudza kukhudzana ndi psinjika, kukaniza Kutentha, kusungunuka zitsulo ndi kugwirizana, solidification, ndi pambuyo kuwotcherera kuzirala. Kumvetsetsa izi kumathandizira kukhathamiritsa magawo owotcherera, kuwongolera mawonekedwe a weld, ndikuwonetsetsa mphamvu zamakina ndi kukhulupirika kwa zolumikizira zowotcherera. Poyang'anira mosamala magawo azowotcherera ndikuwonetsetsa kuti ma elekitirodi apangidwe moyenera komanso kusankha kwazinthu, opanga amatha kupanga mawanga apamwamba kwambiri pamagetsi apakati-frequency inverter spot kuwotcherera.
