Isingeniso
Njengomshini wokushisela onembayo osetshenziswa kabanzi embonini yesimanje, ikhwalithi yokushisela ye-Medium Frequency Spot Welder ithinta ngqo ukuthembeka komkhiqizo nokusebenza kahle kokukhiqiza. Kodwa-ke, amabhizinisi amaningi avame ukunganaki umthelela wemingcele ebalulekile emiphumeleni yokushisela lapho kusetshenziswa ama-Medium Frequency Spot Welders. Lesi sihloko sizohlaziya okuguquguqukayo okubalulekile okuthinta imiphumela yayo ye-welding ezungeze izici eziyinhlokoMedium Frequency Spot Weldersfuthi unikeze iziphakamiso zokuthuthukisa.
1. I-Welding Yamanje: Ingqikithi Yokufaka Amandla
I-Welding current ingumthombo oyinhloko wokukhiqiza ukushisa ku-Medium Frequency Spot Welders, futhi ubukhulu bayo bunquma ngokuqondile ikhwalithi yokwakheka kwe-nugget. Ngokwefomula ethi Q=I² × R × t, yamanje inomthelela omkhulu kakhulu ekukhiqizeni ukushisa kunesikhathi nokumelana. Uma i-current incane kakhulu, indawo ye-weld ayikwazi ukuncibilika ngokugcwele, okuholela emandleni anganele; kuyilapho umthamo wamanje oweqile ungabangela i-spatter, ukuhlehlisa ukujula ngokweqile, nezinye izinkinga.
Iziphakamiso zokuthuthukisa:
- Lungisa inani lamanje ngokuya nge-workpiece kanye nobukhulu. Isibonelo, nciphisa amandla amanje lapho ushisela amashidi azacile ukuze ugweme ukusha{1}.
- Sebenzisa-umsebenzi wokulawula ukunemba ophezulu we-Medium Frequency Spot Welder ukuze ulungise okwamanje-ngesikhathi sangempela{2}}ngempendulo evaliwe{2}}yeluphu ukuze uqinisekise ukuvumelana kokushisela.
2. Isikhathi Sokushisela: Iphoyinti Lebhalansi Lokunqwabelana Kokushisa
Isikhathi sokushisela, sihlanganiswe nesamanje, sithinta usayizi we-nugget namandla we-weld spot. I-Medium Frequency Spot Welder ingafinyelela ukushisela okuphumelelayo ngokulawula ngokunembile isikhathi{1}}sokucindezela, ukushisela, ukubamba, nezinye izigaba.
Iziphakamiso zokuthuthukisa:
- Izimo eziqinile (amanje aphezulu + isikhathi esifushane): Ifanele izinto ezisebenza kakhulu (njengethusi, i-aluminium) ukunciphisa ukulahlekelwa kokushisa.
- Izimo ezibuthakathaka (amanje aphansi + isikhathi eside): Ifanele ukushisela kwensimbi okungafani noma ukuxhunywa kwepuleti eliwugqinsi ukuze kugwenywe ukuwohloka kokushisa okweqile kwendawo.
- Qaphela: Isikhathi esiningi singase sibangele ukushisa ngokweqile futhi kudinga ukulungiselelwa okuhambisanayo nesistimu yokupholisa.
3. Ukucindezela Nokuqina Kwe-Electrode: Isihluthulelo Sokuxhumana Nekhwalithi
Ukucindezela kwe-Electrode kuthinta ngqo ukumelana nokuxhumana phakathi kwe-workpiece ne-electrode. Ukucindezela okufanele kunganciphisa ukumelana nokuxhumana futhi kuthuthukise ukusebenza kahle kokudlulisa ukushisa; kodwa ukucindezela ngokweqile kuzocindezela indawo ye-nugget, okuholela ekunciphiseni amandla.
Iziphakamiso zokuthuthukisa:
- Khetha ingcindezi yesilinda efanelekile (efana no-100N, 200N, njll.) ngokuvumelana nobulukhuni be-workpiece.
- Hlola njalo ukuguga kwethiphu ye-electrode, futhi uwaphungule noma uwashintshe ngokushesha ukuze ugweme ukuminyana okuncishisiwe ngenxa yokwanda kwendawo yokuxhumana.
4. Ukuma kwe-Electrode Nempahla: Izinqumo Zokusabalalisa Ukushisa
Ukuma kwe-electrode (isb., i-tapered, i-spherical) kanye nezinto (isb., ingxubevange yethusi, ithusi le-chromium zirconium) kuthinta ngqo ukuminyana kwamanje kanye nokusabalalisa ukushisa. Isibonelo, ama-electrode ayindilinga afanele ukushisela ama-workpieces agobile, kuyilapho ama-electrode acijile afaneleka kakhulu ukushiselwa kwendawo.
Iziphakamiso zokuthuthukisa:
- Khetha uhlobo lwe-electrode ngokuya ngezidingo zokushisela. Isibonelo, khetha ama-electrode ethusi e-chromium zirconium angagqwala uma ushisela amashidi anamagqabhantshi.
- Hlanza njalo indawo ye-electrode ukuze ugweme ama-oxide noma amabala kawoyela athinta ukusebenza kahle.
5. Indawo yokusebenza kanye nemvelo: Imininingwane Engeke Inganakwa
Ukuhlanzeka kwendawo yokusebenza kanye nezinga lokushisa elizungezile nakho kungathinta kakhulu imiphumela yokushisela. Ukungcola okufana nezingqimba ze-oxide namabala kawoyela kukhulisa ukumelana nokuxhumana, okuholela ekushiseleni okungamanga; kuyilapho{1}}izinga lokushisa eliphezulu lingasheshisa ukuguga kwama-electrode.
Iziphakamiso zokuthuthukisa:
- Susa ukungcola endaweni yokusebenza ngaphambi kokushisela usebenzisa utshwala noma izinto zokuhlanza i-plasma.
- Gcina izinga lokushisa elizinzile kanye nomswakama endaweni yokusebenzela ukuze ugweme ukuphazamiseka kwezindawo eziyingozi kakhulu kumapharamitha wokushisela.
Isiphetho: Ukulawula Kwesayensi Ukuze Kuthuthukiswe Ikhwalithi Yokushisela
Imiphumela yokushisela ye-Medium Frequency Spot Welders incike kumphumela we-synergistic wezinto eziningi ezifana nezamanje, isikhathi, ingcindezi, ama-electrode, nendawo. Ngokulawula ngokunembile lezi zinto eziguquguqukayo nokuhlanganisa ubuchwepheshe bokushintshwa kwemvamisa okuphezulu{1}}kwesistimu{2}}ye-loop impendulo evaliwe, amabhizinisi angathuthukisa kakhulu ikhwalithi yokushisela futhi ehlise izinga lokukhubazeka. Kunconywa ukuthi kuhlanganiswe ukwenziwa kwepharamitha ezinqubweni zokusebenza ezisezingeni futhi kugcinwe okokusebenza njalo ukuze kusetshenziswe ngokugcwele izinzuzo zokuzinza nokuzinza kweMedium Frequency Spot Welders.
