Chiyambi cha Resistance mu Medium Frequency Inverter Spot Welding Machines

Kukaniza kumagwira ntchito yofunika kwambiri pakugwiritsa ntchito makina owotcherera apakati pafupipafupi inverter spot. Kumvetsetsa lingaliro la kukana ndikofunikira kuti tikwaniritse njira zowotcherera malo. Nkhaniyi imapereka chithunzithunzi cha kukana ndi tanthauzo lake mu sing'anga pafupipafupi inverter malo kuwotcherera makina.

1. Kumvetsetsa Kukaniza: Kukaniza ndi chinthu chazinthu zomwe zimalepheretsa kuyenda kwamagetsi. Pankhani ya kuwotcherera malo, kukana kumatanthauza kutsutsidwa komwe kumachitika ndi mphamvu yamagetsi pamene ikudutsa pa workpiece ndi ma electrode.
2. Udindo Wakukaniza mu Spot Welding: Resistance imagwira ntchito zingapo zofunika pamakina owotchera malo:
   • Kutentha Kwambiri: Pamene mphamvu yamagetsi ikudutsa kukana kwa workpiece, imapanga kutentha chifukwa cha zotsatira za Joule. Kutentha kumeneku ndi kofunikira kuti tisungunuke ndi kumangiriza zida panthawi yowotcherera.
   • Ulamuliro Wamakono: Mtengo wotsutsa umatsimikizira kuchuluka kwa zomwe zikuyenda kudzera pa workpiece. Mwa kuwongolera kukana, ogwira ntchito amatha kuwongolera mawotchi apano, kuwonetsetsa kuti kutentha kumalowetsedwa ndikuphatikiza koyenera.
   • Electrode Contact: Kukaniza pa mawonekedwe a electrode-workpiece kumakhudza mtundu wa kukhudzana kwamagetsi. Kuthamanga koyenera kwa ma elekitirodi ndi mawonekedwe apamwamba ndikofunikira kuti muchepetse kukana ndikukwaniritsa bwino magetsi.
3. Zomwe Zimakhudza Kukaniza mu Spot Welding: Zinthu zingapo zimakhudza kukana kuwotcherera pamalo:
   • Katundu Wazinthu: Zida zosiyanasiyana zimakhala ndi mikhalidwe yosiyanasiyana yokana. Zida zopangira, monga mkuwa, zimakhala ndi mphamvu zochepa, pamene zipangizo zotetezera, monga mphira, zimakhala ndi kukana kwakukulu.
   • Makulidwe a Workpiece: Zopangira zokhuthala nthawi zambiri zimawonetsa kukana kwambiri chifukwa cha njira yayitali yomwe ilipo.
   • Pamwamba Pamwamba: Malo oyeretsedwa komanso okonzedwa bwino amaonetsetsa kuti magetsi amalumikizana bwino, amachepetsa kukana.
   • Mapangidwe a Electrode: Maonekedwe, kukula, ndi zinthu za ma elekitirodi zimakhudza kukana pa mawonekedwe a electrode-workpiece.
4. Kuyang'anira Resistance mu Spot Welding: Kuyang'anira kukana kungapereke mayankho ofunikira panthawi yowotcherera malo. Poyesa kukana, ogwira ntchito amatha kuyesa ubwino wa weld, kuzindikira zolakwika zomwe zingatheke kapena kusiyanasiyana, ndikusintha magawo owotcherera moyenerera.

Kutsiliza: Kumvetsetsa kukana komanso gawo lake pamakina owotcherera ma frequency inverter spot ndikofunikira kuti mukwaniritse bwino ma welds. Kukaniza kwa workpiece ndi mawonekedwe a elekitirodi kumatsimikizira m'badwo wa kutentha, kuyenda kwapano, komanso kukhudzana kwamagetsi panthawi yowotcherera. Poganizira zinthu monga katundu wakuthupi, makulidwe a workpiece, mikhalidwe yapamtunda, ndi kapangidwe ka electrode, ogwira ntchito amatha kuwongolera kukana ndikuwongolera magawo awotcherera. Kuyang'anira kukana pakuwotcherera kumapereka chidziwitso chofunikira pamtundu wa weld komanso kumathandizira kusintha kuti pakhale zotsatira zowotcherera.
