Ukuxhathisa ubushushu kumatshini wokuwelda we-Inverter Spot Welding kunye nezinto eziPhembelelayo?

Ubushushu bokumelana yinkqubo esisiseko kumatshini wokuwelda we-inverter indawo ephakathi, apho ukuxhathisa kombane kwi-workpieces kudala ubushushu ngexesha lomsebenzi welding. Eli nqaku lijolise ekuhlolisiseni indlela yokumelana nokufudumala kunye nokuxoxa ngezinto ezahlukeneyo ezichaphazela ukusebenza kwayo kunye nefuthe kwinkqubo ye-welding.

1. I-Resistance Heating Mechanism: Kwi-medium frequency inverter spot welding machines, ukudlula kombane ophezulu wangoku ngokusebenzisa i-workpieces kudala ukuxhathisa kwi-joint interface. Oku kuxhathisa kuguqula amandla ombane kubushushu, okubangela ukufudumeza kwendawo kwindawo ye-welding. Ubushushu obuveliswa kukufudumeza kokumelana budlala indima ebalulekileyo ekufezekiseni ukudibanisa okufanelekileyo kunye nokwenza i-weld nugget enamandla.
2. Izinto ezichaphazela ubushushu bokumelana nobushushu: Izinto ezininzi zinefuthe kwimpumelelo yokumelana nokufudumeza kumatshini wokuwelda we-inverter ophakathi. Le miba ibandakanya: a. Ukuhanjiswa koMbane: Ukuhanjiswa kombane kwezixhobo zokusebenza kuchaphazela ukuchasana kwaye, ngenxa yoko, ubungakanani bobushushu obuveliswayo. Izixhobo ezine-conductivity ephezulu yombane zifumana ukuxhathisa okuphantsi kwaye zivame ukuvelisa ubushushu obuncinci xa kuthelekiswa nemathiriyeli ene-conductivity ephantsi. b. Ukutyeba kweMaterial: Izinto zokusebenza ezityebileyo zibonisa ukuxhathisa okuphezulu ngenxa yendlela ende yangoku, ekhokelela ekwandeni kokuveliswa kobushushu ngexesha le-welding. c. Ukuchasana noQhagamshelwano: Umgangatho woqhagamshelwano lombane phakathi kwe-electrode kunye ne-workpieces ichaphazela kakhulu ukufudumeza ukuxhathisa. Uqhagamshelwano olulambathayo lukhokelela ekuxhathiseni okuphezulu kwi-electrode-workpiece interface, okukhokelela ekunciphiseni ukuhanjiswa kobushushu kunye nokuchaphazela umgangatho we-weld. d. I-Welding yangoku: Ubungakanani be-welding current buchaphazela ngokuthe ngqo ubushushu obuveliswa ngokufudumeza okuxhathisayo. Imisinga ephezulu ivelisa ubushushu obuninzi, ngelixa imisinga esezantsi inokubangela ukufudumeza okungonelanga kunye nokwakheka kwe weld ngokwaneleyo. e. Ixesha le-Welding: Ubude bokusebenza kwe-welding buchaphazela ukufudumeza ukuxhathisa. Amaxesha amade e-welding avumela ubushushu obuninzi ukuba benziwe, okukhokelela kumxube ongcono kunye ne-welds ezinamandla. Nangona kunjalo, amaxesha amade kakhulu e-welding anokubangela ubushushu obugqithisileyo kunye nomonakalo onokuthi ubekho kwizinto zokusebenza. f. I-Electrode Force: Amandla asetyenzisiweyo phakathi kwee-electrode achaphazela uqhagamshelwano lombane kwaye, emva koko, ukufudumeza okuxhasiweyo. Amandla afanelekileyo e-electrode aqinisekisa uqhagamshelwano olufanelekileyo kunye nokuhanjiswa kobushushu ngokufanelekileyo, okunegalelo ekuphuculeni umgangatho we-weld.
3. Impembelelo ye-Resistance Heating: Ukufudumala ukuchasana kunempembelelo ngokuthe ngqo kwinkqubo ye-welding kunye nomgangatho we-weld obangelwayo. Iziphumo eziphambili ziquka: a. Ukuveliswa kobushushu: Ukufudumala kokumelana kunika amandla afunekayo ashushu ukunyibilikisa izinto zokusebenza, ukuququzelela ukudibanisa kunye nokwakhiwa kwe-weld nugget. b. I-Material Softening: Ukufudumeza kwendawo ukusuka ekutshiseni okuxhathisayo kuthambisa izixhobo zokusebenza, kuvumela ukuguqulwa kweplastiki kunye nokukhuthaza ukudibanisa kwe-interatomic kwi-joint interface. c. Indawo echaphazelekayo yokushisa (i-HAZ): Ubushushu obuveliswa ngexesha lokufudumeza ukuchasana nalo luchaphazela izinto ezijikelezileyo, ezikhokelela ekubunjweni kwendawo echaphazelekayo yokushisa (HAZ) ebonakaliswe ngokuguqulwa kwe-microstructure kunye neempawu zomatshini. d. Ukungena kweWeld: Ubungakanani bobushushu obuveliswa ngobushushu obuxhathisayo buchaphazela ubunzulu bokungena kwe-weld. Ukulawulwa ngokufanelekileyo kwegalelo lokushisa kuqinisekisa ukungena okwaneleyo ngaphandle kokunyibilika ngokugqithisileyo okanye ukutshisa.

Ukuqukumbela: Ukufudumeza ukuxhathisa yinkqubo esisiseko kumatshini wokuwelda we-inverter indawo ephakathi, idlala indima ebalulekileyo ekufezekiseni ukudibanisa okufanelekileyo kunye nokwenza iiwelds ezinamandla. Ukuqonda indlela yokumelana nokufudumeza kunye nokuqwalasela izinto ezichaphazelayo, ezifana ne-conductivity yombane, ubukhulu bezinto eziphathekayo, ukuxhathisa ukudibanisa, i-welding yangoku, ixesha le-welding, kunye ne-electrode force, yenza ulawulo olusebenzayo lwenkqubo ye-welding kwaye iqinisekise umgangatho onqwenelekayo kunye nokusebenza. Ngokwandisa ukufudumeza okuxhathisayo, abavelisi banokuphucula ukusebenza kakuhle, ukuthembeka, kunye nokungaguquguquki kwemisebenzi ye-welding kwiindawo ezahlukeneyo zemizi-mveliso.
