Iwe Unoziva nezve Dynamic Resistance Curve muMedium Frequency Inverter Spot Welding Machine?

Iyo dynamic resistance curve ihunhu hwakakosha mune yepakati frequency inverter spot welding michina.Inomiririra hukama pakati peiyo welding ikozvino uye kudonha kwevoltage pama electrode panguva yewelding process.Kunzwisisa iyi curve kwakakosha pakugadzirisa welding maparamendi uye kuve nechokwadi chemhando yepamusoro welds.Muchinyorwa chino, isu tichanyura mune iyo pfungwa yeiyo dynamic resistance curve uye kukosha kwayo mu spot welding application.

1. Tsanangudzo yeDynamic Resistance Curve: Iyo dynamic resistance curve inotaridza kupokana kwepakarepo kunowanikwa panguva yewelding process.Inowanikwa nekuronga welding ikozvino painodonha voltage pamagetsi.Iyi curve inopa ruzivo rwakakosha mumaitiro emagetsi uye ekupisa kweiyo weldment, ichibvumira kunyatso kudzora uye kutarisa kweiyo welding process.
2. Zvinhu Zvinokanganisa Dynamic Resistance Curve: a.Material Properties: Iyo dynamic resistance curve inosiyana nezvinhu zvakasiyana nekuda kwekusiyana kwemagetsi conductivity, thermal conductivity, uye kunyungudika tembiricha.Izvo zvakakosha kuti titarise zvinhu zvemukati kana uchidudzira curve uye nekuona yakanyanya kunaka welding paramita.b.Electrode Configuration: Chimiro, saizi, uye zvinhu zvema electrode zvinopesvedzera nzvimbo yekubata uye yekupisa yekupisa, izvo zvinozokanganisa simba rekudzivirira curve.Kusarudzwa kwakakodzera kwe electrode uye kugadzirisa kwakakosha kuti uwane inowirirana uye yakavimbika welding mhinduro.c.Welding Parameters: Iyo dynamic resistance curve inonzwa kune shanduko muwelding parameters senge welding current, electrode force, uye welding time.Kugadzirisa aya ma paramita anogona kugadzirisa chimiro uye hunhu hwe curve, zvichibvumira optimization yewelding process.
3. Kukosha kweDynamic Resistance Curve: a.Maitiro Ekutarisa: Iyo inosimba yekupikisa curve inopa chaiyo-nguva mhinduro pamhando uye kugadzikana kweiyo welding process.Kutsauka kubva pane inotarisirwa curve chimiro kunogona kuratidza nyaya dzakaita sekushomeka kwemagetsi emagetsi, kusakwana kwekugadzira kupisa, kana kusanganisa zvinhu zvisina kunaka.b.Parameter Optimization: Nekuongorora iyo ine simba yekudzivirira curve, yakakwana welding maparamendi anogona kutariswa kuwana anodiwa weld hunhu, senge kudzika kwekupinda, saizi nugget, uye simba rekubatana.Kunyatsogadzirisa maparamendi ewelding zvichibva pane curve ongororo inosimudzira maitiro ekutonga uye inova nechokwadi chekuenderana weld mhando.c.Mhosva Kuonekwa: Kamwe-kamwe shanduko kana anomalies mune inosimba kuramba curve inogona kuratidza kupfeka electrode, kusvibiswa kwezvinhu, kana kumwe kukanganisa.Kutarisisa curve kunobvumira kukurumidza kutariswa kwenyaya idzi, kugonesa kugadzirisa panguva kana kugadzirisa zviito kudzivirira kukanganisa kwewelding.
4. Measurement Techniques: Dzakasiyana nzira dzinogona kushandiswa kuyera uye kuongorora iyo ine simba yekuramba curve, kusanganisira voltage kudonha yekutarisa, ikozvino sensing matekiniki, uye data kutora masisitimu.Aya matekiniki anobata pakarepo maitiro emagetsi eiyo welding process uye kufambisa kugadzirwa kweiyo dynamic resistance curve.

Iyo inosimba yekupikisa curve mune yepakati frequency inverter spot welding michina chinhu chakakosha chekunzwisisa maitiro emagetsi uye ekupisa kweiyo weldment.Iyo inoshanda segwara rekugadzirisa welding paramita, yekutarisa kugadzikana kwemaitiro, uye kuona zvingangoitika kukanganisa.Nekusimudzira ruzivo rwunopihwa neiyo dynamic resistance curve, vagadziri vanogona kuwana anowirirana uye emhando yepamusoro welds, vachivandudza kugadzirwa kwese uye kuvimbika kwechigadzirwa mukushandisa welding.
