Iko Kubata Kwekupokana paKupisa muMedium Frequency Inverter Spot Welding Machines

Resistance inoita basa rakakosha mukudziya kwepakati frequency inverter spot welding michina.Ichi chinyorwa chinoongorora pesvedzero yekupikisa pane inodziya chiitiko uye zvazvinoreva mukushanda kwenzvimbo welding.

Ohmic Heating:
Ohmic Heating ndiyo yekutanga nzira iyo kupokana kunokanganisa kudziyisa munzvimbo welding.Kana simba remagetsi richipfuura nemuitisi, senge workpiece, kupisa kunogadzirwa nekuda kwekupikisa kunosangana nezvino.Kuwanda kwekupisa kunogadzirwa kwakanyatsoenderana nekupikisa kwemuitisi.
Kubvisa Simba:
Simba rakaparara muworkpiece rinosarudzwa nechigadzirwa chechikwere chezvino (I ^ 2) uye kushorwa (R).Naizvozvo, kuwedzera kwekupokana kunotungamira kune yakakwira simba dissipation, zvichikonzera kupisa kwakanyanya kweiyo workpiece panguva yekushongedza nzvimbo.
Material Properties:
Kupokana kwechinhu kunokonzerwa nekugadzirisa kwayo magetsi.Zvishandiso zvine resistivity yakakwira, senge mamwe maalloys kana simbi isina tsvina, inoratidza kuramba kwakanyanya uye, nekudaro, yakakwirira yekupisa mhedzisiro panguva yewelding.
Saizi yebasa uye geometry:
Saizi uye geometry yeworkpiece inokanganisawo kuramba uye kudziyisa.Mahombe emabasa anowanzo kuve neakanyanya kupikisa nekuda kwekukura kwawo, zvichikonzera kuwedzera kwakanyanya kupisa kugadzirwa panguva yewelding.
Contact Resistance:
Iko kusangana kwekupikisa pakati pe electrode uye workpiece inogona kukanganisa kupisa zvakare.Kusangana kwakashata kweelectrode kana kusvibiswa kwepasi kunogona kuunza kumwe kuramba panzvimbo yekuonana, zvichitungamira kumhepo yekudziya yenzvimbo uye kusawirirana kungangoita mumhando ye weld.
Resistance inoita basa rakakosha mukudziya kwepakati frequency inverter nzvimbo welding michina.Iyo inopesvedzera zvakananga huwandu hwekupisa hunogadzirwa muworkpiece panguva yewelding, iine zvinhu zvakaita senge zvinhu zvivakwa, saizi yebasa, geometry, uye kusangana kwekupokana kunobatsira pakupisa kwese.Kunzwisisa kukanganisa kwekupokana pakudziya kwakakosha pakugadzirisa maparamendi ekuisa nzvimbo, kuve nechokwadi chekugovera kupisa kwakakodzera, uye kuwana akavimbika uye emhando yepamusoro welds.Nekudzora uye nekutarisa mazinga ekupikisa, vashandisi vanogona kunyatso gadzirisa maitiro ekudziya uye kuburitsa mhedzisiro inowirirana mune yavo nzvimbo welding application.
