Chiyambi cha Welding Terminology mu Medium Frequency Inverter Spot Welding Machines

Nkhaniyi ikupereka mawu oyamba kuwotcherera mawu omwe amagwiritsidwa ntchito pamakina owotcherera pafupipafupi a inverter. Kumvetsetsa mawuwa ndikofunikira kwa akatswiri omwe amagwira ntchito ndi makinawa kuti azitha kulumikizana bwino, kuthana ndi mavuto, ndikuwongolera njira zowotcherera. Nkhaniyi ikufuna kudziwitsa owerenga mawu ofunikira omwe amawotchera komanso matanthauzo awo pankhani ya kuwotcherera kwapakati pafupipafupi ma inverter spot.

1. Kuwotcherera Panopa: Kuwotcherera kwamakono kumatanthauza kuyenda kwa magetsi kudzera muzitsulo zowotcherera panthawi yowotcherera. Ndi gawo lofunikira lomwe limatsimikizira kutentha komwe kumapangidwa pamawonekedwe a weld ndipo kumakhudza mtundu ndi mphamvu ya weld. Kuwotcherera kwamakono kumayesedwa mu ampere (A) ndipo kumatha kusinthidwa kuti mukwaniritse zomwe mukufuna.
2. Mphamvu ya Electrode: Mphamvu ya Electrode, yomwe imadziwikanso kuti kuthamanga kwa kuwotcherera, ndikukakamiza komwe kumagwiritsidwa ntchito ndi ma elekitirodi pazigawo zogwirira ntchito panthawi yowotcherera. Ndikofunikira kuti mukhazikitse kulumikizidwa koyenera kwamagetsi ndikuwonetsetsa kuti kutentha kwapang'onopang'ono pa weld spot. Mphamvu ya elekitirodi nthawi zambiri imayesedwa mu ma newtons (N) ndipo iyenera kusinthidwa kutengera makulidwe azinthu ndi zofunikira zowotcherera.
3. Nthawi yowotcherera: Nthawi yowotcherera imatanthawuza nthawi yomwe kuwotcherera kwapano kumagwiritsidwa ntchito pazida zogwirira ntchito. Zimagwira ntchito yofunika kwambiri pakuwongolera kutentha, kuya kwa kulowa, komanso mtundu wonse wa weld. Nthawi yowotcherera imayesedwa mu ma milliseconds (ms) kapena mikombero ndipo imatha kusinthidwa kuti ikwaniritse zomwe mukufuna.
4. Mphamvu Zowotcherera: Mphamvu zowotcherera ndi kuchuluka kwa kutentha komwe kumalowetsedwa muzogwirira ntchito panthawi yowotcherera. Imawerengedwa pochulukitsa kuwotcherera pano ndi nthawi yowotcherera. Mphamvu yowotcherera imakhudza mapangidwe a weld nugget, kuphatikizika, ndi mphamvu zonse zowotcherera. Kuwongolera moyenera mphamvu zowotcherera ndikofunikira kuti tipeze ma welds okhazikika komanso odalirika.
5. Welding Cycle: Njira yowotcherera imatanthawuza kutsatana kwathunthu kwa ntchito zomwe zimafunikira kuti mupange chowotcherera chimodzi. Zimaphatikizanso kutsika kwa ma electrode, kukhudzana ndi ma elekitirodi ndikugwira, kuyenda kwapano, nthawi yozizira, komanso kubweza ma elekitirodi. Kumvetsetsa ndi kukhathamiritsa magawo azowotcherera ndikofunikira kuti mukwaniritse zomwe mukufuna komanso kuchita bwino kwa nthawi yozungulira.
6. Moyo wa Electrode: Moyo wa Electrode umatanthawuza nthawi yomwe ma elekitirodi amatha kukhalabe ndi magwiridwe antchito komanso magwiridwe antchito. Panthawi yowotcherera, maelekitirodi amatha kuvala ndikuwonongeka chifukwa cha zinthu monga kutentha, kupanikizika, ndi ma arcing amagetsi. Kuyang'anira ndi kuyang'anira moyo wa ma elekitirodi ndikofunikira kuti muwonetsetse kuti weld wabwino komanso kupewa kutsika kosafunikira kwa electrode m'malo.

Kutsiliza: Kudziwa mawu oti kuwotcherera ndikofunikira kuti mugwire bwino ntchito ndi makina owotcherera apakati pafupipafupi inverter spot. Kumvetsetsa kwa kuwotcherera pakali pano, mphamvu ya ma elekitirodi, nthawi yowotcherera, mphamvu zowotcherera, kuzungulira kwa kuwotcherera, ndi moyo wama electrode kumathandizira akatswiri kukhathamiritsa njira zowotcherera, kuthana ndi mavuto, ndikuwonetsetsa kuti weld wabwino. Kuphunzira mosalekeza ndi kugwiritsa ntchito mawu oti kuwotcherera kumathandizira kuti pakhale luso komanso chipambano pamagwiritsidwe apakati apakati pa ma inverter spot kuwotcherera.
