Ukukhiqiza Ukushisa kanye Nezici Ezithonya Emishinini Yokushisela I-Resistance Spot

I-Resistance spot welding iyinqubo yokujoyina esetshenziswa kakhulu ezimbonini ezahlukahlukene, okuhlanganisa ukukhiqiza izimoto, i-aerospace, kanye ne-electronics.Phakathi nenqubo yokushisela, ukushisa kukhiqizwa ngokungenakugwenywa, futhi lokhu kukhiqizwa kokushisa kungathinta kakhulu ikhwalithi nobuqotho be-weld.Kulesi sihloko, sizohlola izindlela zokukhiqiza ukushisa emishinini yokushisela indawo yokumelana futhi sihlole izici ezibalulekile ezithonya lokhu kuphuma kokushisa.

Izindlela Zokukhiqiza Ukushisa

Ku-resistance spot welding, izingcezu zensimbi ezimbili noma ngaphezulu zihlanganiswa ngokufaka ingcindezi kanye nokudlulisa amandla kagesi aphezulu ezindaweni zokuthintana.Ukushisa kukhiqizwa ngokuyinhloko ngenxa yalezi zindlela ezilandelayo:

1. Ukushisa Kokumelana: Njengoba ugesi kagesi ugeleza ngezingcezu zensimbi, ukumelana kwezinto kudala ukushisa.Lokhu kushisa kuhambisana ngokuqondile nokumelana kwezinto kanye nesikwele samanje esidlula kuzo, njengoba kuchazwe umthetho kaJoule.
2. Xhumana Nokumelana: Ukumelana nokuxhumana phakathi kwe-electrode kanye ne-workpiece nakho kunomthelela ekukhiqizeni ukushisa.Kuthintwa isimo esingaphezulu, ukuhlanzeka, nokucindezela okusetshenziswa endaweni yokuxhumana.
3. Ukulahlekelwa Kwe-Hysteresis: Ezintweni ze-ferromagnetic, njengensimbi, ukulahleka kwe-hysteresis kwenzeka ngenxa yezinguquko ezisheshayo zamandla kazibuthe odalwe i-current alternating.Lokhu kulahlekelwa kubangela ukukhiqizwa kokushisa okwengeziwe.

Izinto Ezithonya

Kunezici ezimbalwa ezingaba nomthelela kwinani lokushisa elikhiqizwa ekushiseleni indawo yokumelana:

1. I-Welding Yamanje: Ukwandisa i-welding current kuzoholela ekukhiqizeni ukushisa okuphezulu ngenxa yobudlelwane obuqondile phakathi kwamanje nokushisa.
2. I-Electrode Force: Amandla e-electrode aphezulu angakhuphula ukukhiqizwa kokushisa ngokuthuthukisa ukuthintana phakathi kwama-electrode nezinto zokusebenza.
3. I-Electrode Material: Ukukhethwa kwezinto ze-electrode kungaba nomthelela omkhulu ekukhiqizeni ukushisa.Ama-electrode enziwe ngezinto ezinokumelana nogesi okuphezulu, njengethusi, avame ukukhiqiza ukushisa okwengeziwe.
4. I-Workpiece Material: Ukumelana nogesi kwezinto zokusebenza kudlala indima ebalulekile ekukhiqizeni ukushisa.Izinto ezinokumelana okuphakeme, njengensimbi engagqwali, zikhiqiza ukushisa okuningi kunezinto ezinokumelana okuphansi, njenge-aluminium.
5. Isikhathi sokushisela: Izikhathi zokushisela ezinde zingaholela ekwandeni kokukhiqizwa kokushisa njengoba ukushisa kunesikhathi esengeziwe sokuqongelela kusixhumi esibonakalayo sokushisela.
6. Electrode Ithiphu Jiyomethri: Ukuma nesimo samathiphu e-electrode kuthinta ukumelana nokuxhumana, okubuye kube nomthelela ekukhiqizeni ukushisa.

Ku-resistance spot welding, ukuqonda izindlela zokukhiqiza ukushisa kanye nezici ezikuthonyayo kubalulekile ukuze kuzuzwe ukushisela kwekhwalithi ephezulu.Ngokulawula ngokucophelela amapharamitha afana ne-welding current, amandla e-electrode, nokukhethwa kwezinto ezibonakalayo, abakhiqizi bangakwazi ukuthuthukisa inqubo yokushisela ukuze bakhiqize amalunga aqinile futhi anokwethenjelwa kuyilapho benciphisa amandla okuba nokukhubazeka okubangelwa ukushisa okukhulu.Lolu lwazi lunomthelela ekusebenzeni kahle kanye nokusebenza kahle kwe-resistance spot welding ezinhlelweni ezahlukahlukene zezimboni.
