Mphamvu ya Resistance pa Kutenthetsa kwa Resistance Welding Machines

Resistance welding ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga zomwe zimadalira mfundo za kukana kwamagetsi kuti apange zomangira zolimba komanso zolimba pakati pa zigawo zachitsulo.M'nkhaniyi, tiwona mbali yofunika kwambiri yomwe kukana kumagwira pakuwotcha zida zamakina owotcherera.

Resistance welding imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza zamagalimoto, zakuthambo, ndi zamagetsi, chifukwa chotha kupanga ma welds apamwamba kwambiri.Njirayi imaphatikizapo kukakamiza zidutswa ziwiri zachitsulo pamene mukudutsa magetsi.Kukaniza kwamagetsi pamawonekedwe apakati pa zidutswa ziwiri kumatulutsa kutentha, kumapangitsa kuti zisungunuke ndikuphatikizana.

Zinthu zazikulu zomwe zimakhudza kutentha kwa makina owotcherera ndi kukana kwamagetsi komanso kuyenda kwapano.Tiyeni tiwone momwe kukana kumakhudzira kutentha:

1. Katundu:Kukaniza kwamagetsi kwa chinthu kumatengera zinthu zake, monga resistivity ndi conductivity.Zida zokhala ndi resistivity yayikulu zimafuna mphamvu zambiri zamagetsi kuti ziwotche, pomwe zida zowongolera kwambiri zimatentha mwachangu.Makina owotcherera okana amapangidwa kuti azitha kutengera zinthu zosiyanasiyana posintha zomwe zimagwiritsidwa ntchito komanso kukakamiza moyenerera.
2. Mapangidwe a Electrode:Mapangidwe a ma elekitirodi owotcherera amakhudzanso kutenthetsa.Ma elekitirodi amayenera kupangidwa kuchokera kuzinthu zomwe zimatha kupirira kutentha kwambiri komanso kukhala ndi mphamvu zamagetsi zamagetsi.Kukula ndi mawonekedwe a maelekitirodi zimakhudza kugawa kwa kutentha ndi kupanikizika, zomwe zingakhudze ubwino wa weld.
3. Contact Resistance:Kukana kulumikizana pakati pa ma electrode ndi zida zogwirira ntchito kumagwira ntchito yofunika kwambiri pakuwotcha.Kuyanjanitsa koyenera kwa ma elekitirodi ndi kukonza ndikofunikira kuti mutsimikizire kukana kukhudzana.Kukana kukhudzana kwambiri kungayambitse kutentha kosakwanira komanso ma welds ofooka.
4. Kuwongolera Panopa:Kuwongolera molondola kwa kuwotcherera pakali pano ndikofunikira kuti mukwaniritse ma welds okhazikika komanso apamwamba kwambiri.Mulingo wapano uyenera kupangidwa mogwirizana ndi zida zomwe zikulumikizidwa ndi zomwe mukufuna.Kusakwanira kwapano kungayambitse kusakanizika kosakwanira, pomwe kuchulukirachulukira kumatha kuyambitsa kutentha kwambiri komanso kuwonongeka kwa zida zogwirira ntchito.
5. Kugawa Kutentha:Pakuwotcherera kukana, ndikofunikira kuwongolera kagawidwe ka kutentha.Kutentha kosiyana kumatha kubweretsa zovuta zowotcherera monga kuwotcha, kusweka, kapena kulowa kosakwanira.Kuyika koyenera kwa ma electrode ndi kugawa kwamphamvu kumathandiza kuonetsetsa kuti kutentha kwa yunifolomu ndi chomangira cholimba.

Pomaliza, kumvetsetsa mphamvu ya kukana kwamagetsi pamakina otenthetsera makina owotcherera ndikofunikira kuti mukwaniritse ma welds odalirika komanso apamwamba kwambiri.Opanga ayenera kuganizira mozama zakuthupi, kapangidwe ka ma elekitirodi, kukana kukhudzana, kuwongolera kwakanthawi, ndi kugawa kutentha kuti akwaniritse njira yowotcherera pazomwe amafunsira.Pochita izi, amatha kuonetsetsa kuti akupanga zida zolimba komanso zopanda chilema zowotcherera, zomwe zimathandizira kuti zinthu zonse zikhale zodalirika komanso zodalirika.
