Emkhakheni wokukhiqiza izimboni, yonke into emisha kubuchwepheshe bokushisela ithinta kakhulu ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Njengenye yemishini ewumgogodla ye-welding yesimanje yokunemba, imedium frequency spot welding umshinikancane kancane ishintshe amashisela e-AC endabuko futhi yaba ithuluzi elithandwayo ezimbonini ezifana nokukhiqiza izimoto, ukukhiqizwa kwezinto zasendlini, kanye ne-aerospace ngenxa yokusebenza kahle kwayo, ukuzinza, nobuhlakani. Lesi sihloko sizohlinzeka ngohlaziyo olubanzi lwevelu eyingqayizivele yalesi sisetshenziswa kusukela kubukhulu obuhlanganisa izimiso zobuchwepheshe, izinzuzo eziyinhloko, izimo zohlelo lokusebenza, namathrendi wesikhathi esizayo.
I. Isimiso Sobuchwepheshe: Ingabe Umshini Wokushisela Imvamisa Emaphakathi Uzuza Kanjani Ukushisela Okunembayo?
Ubuchwepheshe obuyinhloko be-medium frequency spot welding umshiniilele "ku-inversion yefrikhwensi emaphakathi." Abashisela bendabuko be-AC basebenzisa ngokuqondile u-50Hz noma u-60Hz wamanje oshintshashintshayo, kuyilapho okokusebenza kwefrikhwensi emaphakathi kuqala ngokulungisa amandla e-AC ku-DC, bese iwaguqulela ku-1kHz-4kHz imvamisa emaphakathi AC ngamamojula e-IGBT (Insulated Gate Bipolar Transistor), futhi ekugcineni ikhiphe isiguquli esisehlayo (i-step-down Figuer1). Le ndlela yezobuchwepheshe iletha impumelelo enkulu emithathu:
- Ukulawula Kwamanje Okunembe Kakhulu:Amandla okuphendula asheshayo we-medium frequency current avumela isikhathi sokushisela ukuthi sibe (siqonde ku-millisecond), sigweme ukumosha amandla.
- Okukhiphayo Okuzinzile:I-Medium frequency DC ayinawo uziro-indawo yokuwela, eqinisekisa ukuvumelanisa okungcono phakathi kwamandla e-electrode neyamanje, ithuthukisa kakhulu ukuvumelana kwe-weld.
- Ukusetshenziswa Kwezamandla Okuphansi:Uma kuqhathaniswa namashisela e-AC, okokusebenza kwemvamisa emaphakathi kuthuthukisa ukusebenza kahle kokuguqulwa kwamandla ngaphezu kuka-30%, kunciphisa kakhulu izindleko zokukhiqiza.
- Isibonelo, ekushiseleni umzimba wezimoto, imedium frequency spot welding umshiniingajwayelana-nezidingo zamandla eziphakeme zokuxhuma zamashidi ensimbi anogqinsi oluhlukahlukene ngokulungisa i-waveform yamanje (isb., igagasi lesikwele, i-pulse wave), iqinisekise ukuthi amandla e-weld ahlangabezana nezinga lomkhakha elingu-600MPa nangaphezulu.
II. Izinzuzo Eziyinhloko: Kungani Ukhetha Umshini Wokushisela We-Medium Frequency Spot?
Uma kuqhathaniswa nemishini yokushisela yendabuko, izinzuzo zemedium frequency spot welding umshinizibonakala ngezinhlangothi ezine:
- Ukusebenza Okuphezulu Nokonga Amandla
50% Isivinini Sokushisela Esisheshayo:Ubuchwepheshe befrikhwensi emaphakathi bufinyeza isikhathi samanje sokukhuphuka, okuvumela umjikelezo wokushisela indawo eyodwa ukuthi ulawulwe phakathi kwamasekhondi angu-0.5, okuwenza ulungele imigqa yokukhiqiza.
- 40% Ukusetshenziswa Amandla Okuncishisiwe:Isibonelo, ngemuva kokushintshela kumashisela amabala aphakathi nendawo, inkampani esebenza ekhaya yehlise izindleko zikagesi zaminyaka yonke zisuka ku-1.2 million CNY zaya ku-700,000 CNY.
- Excellent Welding Quality
Amandla Weld Okufanayo:Okukhiphayo okuzinzile kwe-DC yefrikhwensi emaphakathi igwema isenzakalo se-arc blow esivamile ne-AC yomdabu, kunciphisa ubungozi bokushisela okubandayo kanye nama-welds aphuthelwe.
- Ukushisa Okuncane-Indawo Ethintekile (HAZ):Amandla amanje aphezulu agxilisa ukuncibilika endaweni yokushisela, enciphisa izinga lokuguga ngo-60%, okuyenza ifaneleke ngokukhethekile ukushiselwa kwengxenye ye-elekthronikhi.
- Ukuzivumelanisa nezimo okuqinile
Ihambisana Nezinto Eziningi:Ngokulungisa amapharamitha amathathu wamanje, ingcindezi, nesikhathi, ingashisela izinto eziyinselele njenge-aluminium ingxubevange, insimbi ekhangayo, nengxube yethusi.
- Isekela Izimo Zokusebenza Eziyinkimbinkimbi:Imishini yokushisela indawo yefrikhwensi emaphakathi efakwe izinhlelo zokulawula eziguquguqukayo inganxephezela ngokuzenzakalelayo izinto eziguquguqukayo ezifana nokuguga kwama-electrode kanye ne-oxidation yendawo yokusebenza.
- Ukuthuthukiswa Okuhlakaniphile
Okwesimanjeimishini yokushisela amabala aphakathi nendawo hlanganisa amamojula e-IoT, asekele-ukuqapha idatha yesikhathi sokushisela, ukugcinwa kwamafu kwamapharamitha enqubo, kanye nephutha预警 (isixwayiso sangaphambi kwesikhathi). Isibonelo, inkampani yezimoto yasebenzisa idatha ye-weld curve ekhiqizwe imishini ukunciphisa izinga lokulimala komkhiqizo lisuka ku-0.8% liye ku-0.2%.
III. Izimo Zohlelo Lokusebenza: Kusukela Ekwenziweni Kwezimoto kuya ku-Precision Electronics
Ukusetshenziswa okubanzi kweimishini yokushisela amabala aphakathi nendawoiqinisekisa inani labo lobuchwepheshe:
