Resistance Heating muMedium Frequency Inverter Spot Welding Machines uye Izvo Zvinokurudzira Zvinhu?

Resistance heat inzira yakakosha mune yepakati frequency inverter spot welding michina, uko kupikisa kwemagetsi kwezvishandiso zvinogadzira kupisa panguva yekushanda kwewelding.Ichi chinyorwa chine chinangwa chekuongorora magadzirirwo ekudzivirira kudziyisa uye kukurukura zvakasiyana siyana zvinopesvedzera kushanda kwayo uye kukanganisa pakuita welding.

1. Resistance Heating Mechanism: Mukati-frequency inverter spot welding michina, kupfuura kweakakwira magetsi ikozvino kuburikidza neanoshanda maworkpiece kunogadzira kupokana mujoint interface.Kupikiswa uku kunoshandura simba remagetsi kuita kupisa, zvichikonzera kupisa kwenzvimbo panzvimbo yewelding.Iko kupisa kunokonzerwa nekupisa kupisa kunoita basa rakakosha mukuwana fusion yakakodzera uye kugadzira yakasimba weld nugget.
2. Zvinhu Zvinokanganisa Resistance Heating: Zviitiko zvinhu zvinopesvedzera kushanda kwekupokana kupisa mukati mepakati frequency inverter spot welding michina.Zvinhu izvi zvinosanganisira: a.Electrical Conductivity: Iyo yemagetsi conductivity yezvinhu zveworkpiece inokanganisa kuramba uye, nekudaro, huwandu hwekupisa hunogadzirwa.Zvishandiso zvine epamusoro emagetsi conductivity zvinowana kushomeka kwekudzivirira uye zvinowanzoita kudziya kushoma kana zvichienzaniswa nemidziyo ine yakaderera conductivity.b.Hukuru hwezvinhu: Zvishongo zvakakora zvinoratidza kuramba nekuda kweiyo nzira refu iripo, zvichikonzera kuwedzera kupisa kwechizvarwa panguva yewelding.c.Bata Resistance: Hunhu hwekusangana kwemagetsi pakati pema electrode uye maworkpieces anokanganisa zvakanyanya kupisa kupisa.Kubata zvisina kunaka kunotungamira kupikisa kwepamusoro pa electrode-workpiece interface, zvichikonzera kudzikira kwekutamisa kupisa uye zvinogona kukanganisa weld mhando.d.Welding Current: Hukuru hweiyo welding ikozvino inokonzeresa kupisa kunogadzirwa kuburikidza nekudziisa kupisa.Mhepo dzepamusoro dzinounza kupisa kwakawanda, nepo kuderera kwemhepo kunogona kukonzera kusakwana kwekudziya uye kusakwana kuumbwa kweweld.e.Welding Nguva: Iyo nguva yekushanda kwewelding inokanganisawo kupokana kupisa.Nguva refu yewelding inobvumira kuti kupisa kwakawanda kugadzirwe, zvichitungamira kune nani fusion uye maweld akasimba.Nekudaro, nguva yakawandisa yekurebesa welding inogona kukonzera kupisa uye zvinogona kukuvadza kune workpieces.f.Electrode Force: Simba rinoshandiswa pakati pema electrode rinokanganisa kubata kwemagetsi uye, zvichizodaro, kupisa kwekupokana.Simba re electrode rakakwana rinoita kuti pave nekusangana kwakaringana uye kufambiswa kwekushisa kwakanaka, zvichibatsira pakuvandudza kunaka kweweld.
3. Mhedzisiro yeResistance Heating: Resistance kudziyisa kune yakananga mhedzisiro pane welding maitiro uye inokonzeresa weld mhando.Mhedzisiro yakakosha inosanganisira: a.Heat Generation: Resistance heat inopa inodiwa yekupisa simba kunyungudutsa iyo workpiece zvinhu, kufambisa fusion uye kuumbwa kweweld nugget.b.Material Kupfava: Iyo yekudziya yenzvimbo kubva pakudziisa inopfavisa iyo workpiece zvinhu, zvichibvumira kushanduka kwepurasitiki uye kukurudzira interatomic bonding pajoint interface.c.Heat Affected Zone (HAZ): Kupisa kunogadzirwa panguva yekudzivirira kupisa kunokanganisawo zvinhu zvakapoteredzwa, zvichitungamira pakuumbwa kwenzvimbo yekushisa yakakanganiswa (HAZ) inoratidzwa neyakagadziriswa microstructure uye mechanical properties.d.Weld Penetration: Huwandu hwekupisa hunogadzirwa kuburikidza nekudzivirira kudziyisa hunoita hudzamu hwekupinda kweweld.Kudzora kwakaringana kwekupisa kwekupisa kunovimbisa kupinda kwakakwana pasina kunyungudika kwakanyanyisa-kuburikidza kana kupisa-kuburikidza.

Mhedziso: Resistance heat inzira yakakosha mune yepakati frequency inverter spot welding michina, ichiita basa rakakosha mukuwana fusion chaiyo uye kugadzira maweld akasimba.Kunzwisisa magadzirirwo ekudzivirira kupisa uye nekutarisa zvinhu zvinopesvedzera, senge magetsi conductivity, ukobvu hwezvinhu, kusangana nekupokana, welding ikozvino, welding nguva, uye electrode simba, inogonesa kutonga kunoshanda kweiyo welding maitiro uye inovimbisa inodiwa weld mhando uye kuita.Nekukwenenzvera kudziyisa kupisa, vagadziri vanogona kusimudzira kugona, kuvimbika, uye kuenderana kwenzvimbo welding mashandiro mune akasiyana maindasitiri ekushandisa.
