Intshayelelo
Njengesixhobo esingundoqo sobugcisa kwintsimi ye-welding yanamhlanje, umgaqo wokusebenza wemedium frequency indawo welding machineidibanisa iteknoloji ye-elektroniki yamandla kunye nethiyori yolawulo oluchanekileyo. Xa kuthelekiswa noomatshini bokuwelda amandla emveli,medium frequency spot weldersukufezekisa ukuphuculwa kwempumelelo kumgangatho we-welding kunye nokusebenza kakuhle ngetekhnoloji ye-inverter. Eli nqaku lichaza ngokucwangcisiweyo umgaqo wokusebenza kunye neenzuzo zobugcisa ze-medium frequency spot welding machines ngokweembono zokuguqulwa kwamandla, ulawulo lwenkqubo ye-welding, kunye neziphumo ze-thermodynamic.
1. Umsebenzi ongundoqo
Ukusebenza komatshini wokuwelda amabala aphakathi kusekwe kwikhonkco lokuguqula amandla "AC → DC → Medium Frequency AC → Welding," equka la manyathelo aphambili alandelayo:
- Igalelo laMandla kunye noLungiso
Isixhobo siqhagamshelwe kwisigaba sesithathu-isigaba se-380V samandla ombane ofumaneka rhoqo kwi-AC. Amandla e-AC aguqulelwa kumandla e-DC atyhutyhayo ngokusebenzisa imodyuli epheleleyo-yokulungisa ibhulorho. Eli nqanaba lisebenzisa iteknoloji yokulungiswa kwe-thyristor, evumela ukulungelelanisa i-angle yesigaba segalelo langoku ukuphumeza i-0-100% yolawulo lwangaphambili lwamandla, ukunciphisa impembelelo yegridi.
- Uguqulo kunye nokuNyuswa kwamaxesha
Amandla eDC alungisiweyo acutshungulwa yi-IGBT (I-Insulated Gate Bipolar Transistor) imodyuli yoguqulo, eyenza ukutshintshwa kwesantya esiphezulu-ku-1-4 kHz ukuvelisa medium{6}}i-frequency square wave AC amandla. Umzekelo, imodeli ye-200kVA yohlobo oluthile ifezekisa ukusebenza kakuhle kwe-inversion ye-98%, kunye nokulahlekelwa kwamandla kuphela kwisinye kwisithathu seso siguquli samandla esiqhelo.
- Phezulu-Inyathelo lesiGuquli seFrequency{1}}Ezantsi
Umbane ophakathi-obuxhakaxhaka be-AC udlula -kwi-frequency transformer ene-nanocrystalline alloy core, inciphisa amandla ombane ukusuka ku-600V ukuya kuluhlu olukhuselekileyo lwe-5{4}}20V ngelixa isonyusa langoku ukuya kwi-welding{9}}inqanaba lezinga le-5,000-A30,0,0. Le nkqubo iphakamisa iimpawu ze-high-frequency ukunciphisa umthamo we-transformer nge-60% kunye nobunzima nge-50%.
- DC Welding Output
Isekethe yesibini iphinda ihlaziywe ngeqela lee-diode ezikhawulezayo -zokubuyisela kwakhona, ikhupha amandla eDC kunye ne-ripple coefficient engaphantsi kwe-5%. I-DC welding yangoku ithintela ukuphazamiseka kwe-electromagnetic okuqhelekileyo koomatshini be-welding bemveli be-AC kwaye iqinisekisa ukubunjwa okuzinzileyo kwe-nugget xa izinto ze-welding ezifana ne-aluminium alloy kunye namaphepha afakwe igalvanized.
2. Ulawulo lwe-Thermodynamic yeNkqubo ye-Welding
Oomatshini bokuwelda bamabala aphakathiukufikelela{0}kumgangatho ophezulu welding ngolawulo oluchanekileyo lobushushu:
- Qhagamshelana noMgaqo wokuNchasa
Ii-Electrodes zisebenzisa i-200-i-600kgf yoxinzelelo lokuphelisa iileya ze-oksidi ezingaphezulu kwi-workpieces, ukunciphisa ukuxhathisa koqhagamshelwano kwi-50-200μΩ. Izinzwa zoxinzelelo lwe-Dynamic kwi-medium frequency spot welding machines zibeka iliso ngexesha lokwenyani, ziqinisekisa ukuguquguquka kokumelana kulawulwa ngaphakathi kwe-±3%.
- UPhuculo lweWaveform yangoku
Phakathi{0}}itekhnoloji yoguqulo oluqhelekileyo inokukhupha iifomati ezahlukeneyo zamaza, ezinje ngetrapezoidal kunye namaza epulsed. Xa welding 0.5mm steel stainless, a multi - imo yepulse (umzekelo, 10kA preheating for 2ms ilandelwa 15kA main welding for 5ms) ngempumelelo ukuthintela spatter kwaye iphucula ukuxinana nugget.
- I-Thermal Balance Mechanism
Isixhobo esakhelwe-kwisixokelelwano sokupholisa (ubushushu bamanzi ngama-25 degrees ±2℃) ithwala i-70% yobushushu be-electrode. I-algorithm ye-PID ilungisa isantya sokuhamba kwamanzi ukuqinisekisa ukuba ukunyuka kweqondo lokushisa kwe-electrode akudluli kwi-150 degree. Idatha yokuvavanya ukusuka kumgca wokuvelisa iimoto ibonise ukuba emva kwe-welds ye-500 elandelelanayo, ukushisa kwe-electrode kwanda ngama-82 degrees kuphela.
3. Umahluko kwezobuGcisa xa kuthelekiswa noomatshini bokuwelda baMandla eSintu
