Magawo a Pressure Application mu Medium Frequency Inverter Spot Welding Machines?

Mu sing'anga pafupipafupi inverter malo kuwotcherera makina, ntchito kuthamanga ndi sitepe yovuta mu ndondomeko kuwotcherera. Kupanikizika komwe kumayikidwa pakati pa ma elekitirodi ndi zida zogwirira ntchito kumakhudza mtundu ndi mphamvu ya cholumikizira chowotcherera. Nkhaniyi ikufotokoza magawo omwe amakhudzidwa ndi njira yogwiritsira ntchito kuthamanga pamakina owotcherera ma frequency inverter spot.

1. Gawo Loyamba Lolumikizirana: Gawo loyamba la kukakamiza ndikulumikizana koyambirira pakati pa ma electrode ndi zida zogwirira ntchito:
   • Ma electrode amalumikizidwa ndi zida zogwirira ntchito, kuwonetsetsa kuti zikuyenda bwino komanso kukhazikika.
   • Kuthamanga kopepuka koyambirira kumayikidwa kuti akhazikitse kukhudzana kwamagetsi ndikuchotsa zonyansa zilizonse kapena zigawo za oxide.
2. Pre-Compression Stage: Gawo la pre-compression limaphatikizapo kukulitsa pang'onopang'ono kukakamiza kogwiritsidwa ntchito:
   • Kupanikizika kumawonjezeka pang'onopang'ono kuti akwaniritse mlingo wokwanira wowotcherera bwino.
   • Gawoli limatsimikizira kulumikizana koyenera kwa electrode-to-workpiece ndikukonzekeretsa zida zowotcherera.
   • Gawo la pre-compress limathandizira kuthetsa mipata iliyonse ya mpweya kapena zosokoneza pakati pa ma electrode ndi zida zogwirira ntchito, kuonetsetsa kuti weld yokhazikika.
3. Gawo Lowotcherera: Mukangofuna kukakamizidwa, gawo lowotcherera limayamba:
   • Ma electrode amakhala ndi mphamvu yokhazikika komanso yowongoleredwa pazantchito panthawi yonseyi.
   • The kuwotcherera panopa ntchito, kutulutsa kutentha pa maelekitirodi-to-workpiece mawonekedwe, kuchititsa kusungunuka kusungunuka ndi wotsatira mapangidwe kuwotcherera.
   • Gawo la kuwotcherera nthawi zambiri limakhala ndi nthawi yodziwika kutengera momwe zinthu zimayendera komanso zofunikira.
4. Post-Compression Stage: Pambuyo powotcherera, gawo la post-compression likutsatira:
   • Kupanikizika kumasungidwa kwakanthawi kochepa kuti alole kulimba ndi kuziziritsa kwa cholumikizira cha weld.
   • Gawoli limathandiza kuonetsetsa kusakanikirana koyenera ndi kuphatikizika kwachitsulo chosungunuka, kupititsa patsogolo mphamvu ndi kukhulupirika kwa weld.

Kukakamiza kugwiritsa ntchito makina owotcherera apakati pafupipafupi inverter malo kumaphatikizapo magawo angapo, chilichonse chimagwira ntchito inayake pakuwotcherera. Gawo loyambirira lolumikizana limakhazikitsa ma electrode-to-workpiece kukhudzana, pomwe siteji ya pre-compression imatsimikizira kulumikizana koyenera ndikuchotsa mipata ya mpweya. Gawo la kuwotcherera limagwiritsa ntchito kukakamiza kosasintha pomwe kuwotcherera kumapangitsa kutentha kuti apange weld. Pomaliza, siteji ya post-compression imalola kulimba ndi kuziziritsa kwa cholumikizira cha weld. Kumvetsetsa ndikuchita bwino gawo lililonse la ntchito yokakamiza ndikofunikira kuti mukwaniritse ma welds apamwamba kwambiri okhala ndi mphamvu zokwanira komanso kukhulupirika pamakina apakati pafupipafupi inverter spot kuwotcherera.
