Ekwenziweni kwe-chassis yezimoto, izindlu zebhethri zamandla amasha, kanye{0}}nezingxenye zesakhiwo ezinamandla aphezulu, ikhwalithi yamantongomane{1}}kuya{2}}kuma-stamping steel welds ithinta ngokuqondile ukuphepha komkhiqizo, ukuqina, nokunemba kokuhlanganiswa. Nokho, abakhiqizi abaningi bayaqhubeka nokubhekana nezinkinga ezivamile ezifana nokushisela okubuthakathaka, i-spatter eyeqile, ukuhlehlisa okungalingani, noma ngisho nokuqhekeka kwensimbi.
Nakuba lezi zinkinga ngokuvamile zibangelwa iphutha lomsebenzisi, umsuka wangempela ngokuvamile usemandleni obuchwepheshe emishini yokushisela. Lesi sihloko sihlola izinselelo ezijwayelekile zokushisela, igqamisa izinzuzo ezibalulekile ze-medium-frequency (MF)imishini yokushisela amabala, futhi inikeza isiqondiso esisebenzayo sokukhetha kanye nokwenza kahle okokusebenza ukuze kuxazululwe izinselele zokukhiqiza.
Isizathu Esiyinhloko Sezinkinga Zekhwalithi Ye-Weld: Ukulawulwa Kwepharamitha Okwanele
Imikhawulo ye-Conventional Spot Welders
Ama-spot welder ajwayelekile-emvamisa (50/60Hz) ama-spot welder avame ukubonisa ukushintshashintsha okukhulu kwamanje (±5% noma ngaphezulu), okuholela ekwakhekeni kwe-nugget engalingani. Lokhu kuyinkinga ikakhulukazi uma sishisela amantongomane-ensimbi yokugxiviza yamandla aphezulu, okuholela kulokhu:
- Ama-weld abuthakathaka noma ahlukanisiwe
- I-spatter eyeqile ithinta ukubukeka nokuhlanganisa
- Ukuhlehlisa okungalingani, kunciphisa amandla ahlangene
Ekukhiqizeni{0}ivolumu ephezulu, lezi zinkinga zikhuphula ngokuqondile amanani okusebenza kabusha, ukusebenza kahle okuphansi, futhi zingafaka engozini ukuphepha kwemoto.
Izinzuzo Zokushisela-Imvamisa Yendawo
Ama-Spot spot welder-amaphakathi, njengalawo athuthukiswe i-Haifei, asebenzisa cishe ubuchwepheshe bokuguqula i-inverter obungu-1000Hz obuhlanganiswe nezilawuli zobunikazi. Lokhu kusetha kunciphisa ukushintshashintsha kwamanje kuye ngaphansi kuka-±1%, kuthuthukisa kakhulu ukuzinza kwe-weld nokuphindaphinda.
- Isibonelo:Umkhiqizi ohamba phambili wezingxenye zezimoto ubike ukuthi ngemuva kokusebenzisa ama-spot welders e-Haifei MF, amandla e-M8 flange nut weld anyuke ngo-30%, izinga le-spatter lehla ngaphansi kuka-0.5%, nokusebenza kahle kokukhiqiza kwaba ngcono ngo-15%.
- Iseluleko Esisebenzayo:Lapho ukhetha i-spot welder, beka phambili okokusebenza ngokuzinza okuphezulu kwamanje, ukulawula okunembayo, nokusabela okusheshayo. I-inverter-emaphakathi ehlanganiswe nezilawuli ezihlakaniphile iwukhiye wekhwalithi yokushisela engaguquki.
Izinselelo ku-Welding Stamping Steel kanye nezixazululo ezisebenzayo
Izitembu zensimbi ezifana ne-22MnB5 ziletha izinselelo eziyingqayizivele zokushisela:
- Amandla aphezulu kanye ne-thermal conductivity ephansi kwandisa ingozi yokushisa kwendawo
- Ijwayele ukuqhekeka kanye ne-oxidation
- Ukushisela kudinga ukunemba okuphezulu ukuze kugcinwe ukuvumelana kwe-weld
Izinzuzo Zokulawula-Isiteji Amandla Esiteji
Ama-spot welder e-Haifei MF afaka-izigaba eziningi zokusabalalisa amandla nezindlela zokushisa kuqala, aqinisekisa ngisho nokudlulisa ukushisa futhi avimbele ukushisa ngokweqile noma ukuqhekeka.
Izici Zobuchwepheshe Ezibalulekile Nezinzuzo:
| Isici | Inzuzo | Umphumela Wangempela |
| Amamojula e-IGBT + Isiguquli Esingokwezifiso | Isilinganiso esiphezulu sifinyelela ku-40kA | Ingakwazi ukushisela insimbi ewugqinsi engu-0.8–4.0mm |
| -Ukulawula Amandla Esiteji Okuningi | Shisisa kuqala → Weld → Cool | Amandla e-post{{0}weld tensile afinyelela ku-600MPa, ahlangabezana namazinga ensimbi yokugxiviza |
| Isilawuli Esihlakaniphile | Ukuqapha{0}}isikhathi sangempela samanje, i-voltage, ingcindezi | Ukuvumelana kwe-weld okuthuthukisiwe, kwehliswe ama-weld abuthakathaka ngo-70% |
Inkomba yomkhakha:Umkhiqizi wemoto entsha yamandla ubike{{0}amandla e-weld tensile angaphezu kuka-600MPa, ahlangabezana ngokugcwele nezimfuneko zensimbi yokugxiviza. I-oxidation ebusweni kanye nokuhlehlisa bekukuncane, kunciphisa kakhulu ukusebenza kabusha.
Isiqondiso Esisebenzayo:
- Nge-stamping steel, khetha ama-welders asekela{0}}ukulawula amandla esiteji esiningi.
- Khetha umthamo wamanje ophezulu ofanele ukushuba kwezinto.
- Lungisa-izimiso zokushisela ezifana nomfutho we-electrode, isikhathi sokushisela, nezinga lokushisa lokushisa ngaphambi kwesikhathi ukuze kuhambisane kahle.
Ukuqinisekisa{0}}Ukuthembeka Kwesikhathi Eside Se-Weld: Ukuzinza Kwezisetshenziswa Nesevisi
Ikhwalithi yokushisela engaguquki ngokuhamba kwesikhathi ayincikile kuphela ekulawuleni okunembayo kwamanje kodwa futhi nasekuthembekeni kwemishini nokusebenza kahle kokugcinwa kwayo.
I-Haifei MF spot welders iqinisekisa ukuzinza kokusebenza ngokusebenzisa:
