Inzuzo engundoqo yecapacitive discharge spot welderilele kwinkqubo yokutshaja kunye nokukhupha i-capacitor, efezekisa umtsi osemgangathweni kulawulo lwamandla xa kuthelekiswa nezixhobo zokuwelda zemveli:

Umgaqo wophumezo lobuchwephesha:

• Ifomula yamandla ekhawulezileyo: E=0.5×C×V²
• (C=ixabiso le-capacitance, V=amandla ombane wokutshaja)
• Ngenkqubo yokulawula amandla ombane aphezulu-echanekileyo (± 0.5V impazamo) kunye nemodyuli yokutshintsha ngokukhawuleza kwe-IGBT, impazamo yamandla okukhutshwa ngakunye kuqinisekiswa ukuba<±1%.

2. I-Microsecond -iNqanaba lokuLawula iWaveform yokukwazi

• Icapacitive discharge spot welderixhasa inkqubo entsonkothileyo yokukhupha i-waveform, ivumela ukukhutshwa kwamandla egophe kwiipropathi zezinto ezahlukeneyo:
• Inqanaba lesithathu -indlela yokukhutshwa kwamaza:
• Ngaphambi-inqanaba lokukhupha (0.5ms): Susa ukuxhathisa uqhagamshelwano
• Inqanaba lokukhupha eliphambili (2-8ms): Ifom ye-weld nugget
• Inqanaba lokuthomalalisa (1ms): Phucula i-microstructure
• Isicelo esisebenzayo:
• Xa ishishini lesixhobo sonyango lidityaniswe nge-0.1mm titanium alloy sheets ezibhityileyo, lamkela imo ye-"double{1}}peak pulse" (i-pulse engundoqo + isongezelelo samandla esibini), inyusa amandla e-weld ukusuka kwi-320MPa ukuya kwi-450MPa{5}}ukufikelela kwi-95% yesiseko samandla ezinto.

II. Inkqubo yeMbuyekezo ye-Dynamic Impedance: I-Adaptive Revolution yeeMeko zokuSebenza eziNxibelele

1. Ixesha lokwenyani{1}}lokuJonga iMpedance kunye neMbuyekezo

Icapacitive discharge spot welderixhotyiswe ngenkqubo yoluvo olukrelekrele eyenza i-millisecond{0}}inqanaba lohlengahlengiso oluguqukayo ngexesha lenkqubo yokuwelda:

Undoqo we-algorithm yembuyekezo:

• Ixabiso lembuyekezo yombane oguqukayo ΔV=K×(R_Eyokwenene - R_base)/R_base×V_set
• (K=umlinganiso wemathiriyeli, R_Eyokwenene=yokwenyani{3}}yexesha lokungabikho, R_base=ixabiso lesalathiso)
• Le algorithm inokulawula ukuguquguquka kwamandla ngexesha le-welding yesinyithi engafaniyo ngaphakathi kwe-± 2%.

2. Ukusetyenziswa kwiimeko ezine eziQhelekileyo

• Imbuyekezo yotshintsho lwesiquphe kubukhulu bezinto:
• Kwi-welding yeemodyuli zebhetri yemoto entsha, inkqubo ichonga ngokuzenzekelayo umahluko wobunzima phakathi kwe-0.3mm yefoyile yobhedu kunye ne-2mm yentsimbi yegobolondo, inyusa uxinzelelo lwe-electrode ukusuka kwi-200N ukuya kwi-850N ukuqinisekisa ubunzulu be-weld nugget.
• Ukuziqhelanisa nokungcoliseka komphezulu:
• Xa ishishini le-3C lidityaniselwe i-nickel -iitheminali ezifakwe kwi-plated, inkqubo ibone umaleko we-oxide oyi-0.05mm kwaye yandise ngokuzenzekelayo amandla okukhupha nge-12%, inyusa izinga lesivuno ukusuka kwi-82% ukuya kwi-99.5%.
• Ukulungiswa kokukhukuliseka kobushushu:
• Xa ukusebenza ngokuqhubekayo kwezixhobo kubangela ukuba ukushisa kwe-capacitor kunyuke kwi-degree ye-45, inkqubo iyanciphisa i-voltage yokutshaja nge-coefficient ye-0.5V / i-degree ukugcina ukuzinza kokuphuma kwamandla.
• Imbuyekezo yokunxitywa kwe-electrode:
• Imodeli yemathematika phakathi kokunxitywa kwedayamitha ye-electrode kunye nembuyekezo yoxinzelelo isekiwe:
• P_comp=P0×(D0/D_yangoku)^1.5
• (D0=idiameter entsha ye-electrode, D_yangoku=idayamitha yangoku)
• Emva kokuba ishishini le-aerospace lisebenzise le modeli, ubomi benkonzo ye-electrode bandiswa ukusuka kumabala angama-8,000 ukuya kumabala angama-25,000.
