I-Mid-Frequency Direct Current Spot Welding Process Data

I-Spot welding yinkqubo yokudibanisa ebalulekileyo esetyenziswa kakhulu kumashishini ahlukeneyo, ukusuka kwimveliso yeemoto ukuya kwimveliso yombane. Kwiminyaka yakutshanje, i-middle-frequency ngqo ye-spot welding iye yafumana ukuduma ngenxa yokuchaneka kwayo kunye nokusebenza kakuhle. Kweli nqaku, sihlalutya imiba ephambili yobu buchule bokuwelda, sivavanya inkqubo yayo, iingenelo, kunye nedatha yesicelo.

Ukuqonda i-Mid-Frequency Direct Current Spot Welding

I-Mid-frequency current current (MFDC) spot welding yindlela yokuwelda ekhethekileyo esebenzisa umsinga othe ngqo kuluhlu lwamaza aphakathi, phakathi kwe-1000 Hz kunye ne-100 kHz. Ngokungafaniyo neendawo zokuwelda zangoku (AC) indawo yokuwelda, ukuwelda kwendawo ye-MFDC isebenzisa unikezelo lombane olusekwe kwi-inverter, inika iingenelo ezininzi ezahlukeneyo.

Izinto eziluncedo ze-MFDC Spot Welding

1. Ulawulo olomeleziweyo: I-welding ye-MFDC inikezela ngolawulo oluchanekileyo kwi-weld yangoku kunye nexesha, ekhokelela kwi-welds ehambelanayo kunye nekhwalithi ephezulu.
2. UkuNcitshiswa kokusetyenziswa kwamandla: Ukusetyenziswa kweziphumo zangoku ngokuthe ngqo kwi-transfer yamandla esebenzayo, okukhokelela ekunciphiseni ukusetyenziswa kwamandla xa kuthelekiswa ne-AC welding.
3. Ukuphuculwa koMgangatho weWeld: I-welding ye-MFDC inciphisa ukuhluka kwimveliso yokushisa, ukunciphisa amathuba okuba neziphene ezifana nokutshisa okanye i-welds ebuthakathaka.
4. Ukonyuka koBomi be-Electrode: Ngenxa yokunciphisa i-electrode yokugqoka, i-welding ye-MFDC inokwandisa kakhulu ubomi be-electrode, ukunciphisa ixesha lokunciphisa ukugcinwa.

Iiparamitha zeNkqubo kunye neDatha

Ukwandisa ukusebenza kwe-MFDC welding spot, iiparamitha ezininzi ezibalulekileyo kunye namanqaku edatha kufuneka athathelwe ingqalelo:

1. Weld yangoku: Isixa sangoku esidlulayo kwi-electrodes ngexesha le-welding ichaphazela amandla kunye nomgangatho we-weld. Ngokwesiqhelo kulinganiswe ngeekhilomperes (kA), i-weld current efanelekileyo ixhomekeke kwizinto ezidityaniswayo.
2. Ixesha le-Weld: Ubude bexesha lokuhamba kwangoku, kulinganiswe ngeemilliseconds (ms), yenye iparameter ebalulekileyo. Kufuneka ilawulwe ngokuchanekileyo ukuqinisekisa i-weld eyomeleleyo kwaye engaguqukiyo.
3. I-Electrode Force: Amandla asetyenziswa yi-electrode kwizinto zokusebenza zichaphazela umgangatho we-weld. Ilinganiswa ngee-kilonewtons (kN).
4. Izinto ze-Electrode: Ukukhethwa kwezinto ze-electrode kuchaphazela ukunxiba kwe-electrode kwaye, ngenxa yoko, ukugcinwa kwamaxesha.
5. Uluhlu lweWelding: Indibaniselwano ye-weld current, ixesha, kunye ne-electrode force idla ngokubizwa ngokuba “yi-welding schedule.” Izinto ezahlukeneyo kunye nezicelo zifuna iishedyuli ezithile ze-welding ukuze ufumane iziphumo ezilungileyo.

Usetyenziso lwe-MFDC Spot Welding

I-Mid-frequency ngqo ngoku welding yendawo ifumana ukusetyenziswa kuluhlu olubanzi lwamashishini:

1. UkuVeliswa kweeMoto: Isetyenziselwa ukudibanisa amalungu omzimba wesithuthi, ukuqinisekisa imfezeko yesakhiwo kunye nokhuseleko.
2. Electronics: Ilungele ukudibanisa amacandelo ombane kwiibhodi zeesekethe eziprintiweyo, ukugcina i-conductivity kunye nokuthembeka.
3. I-Aerospace: Isetyenziselwa ukuwelda amacandelo abalulekileyo apho ukuchaneka kunye nomgangatho ophezulu wamalungu ayimfuneko.
4. Izixhobo zombane: Ukuqinisekisa uqhagamshelo oluhlala ixesha elide kwizixhobo zasekhaya, ukwandisa ixesha elide lemveliso.

Ukuqukumbela, i-mid-frequency ngqo yangoku ye-welding yendawo inika inzuzo enkulu ngokuchaneka, ukusebenza kakuhle, kunye nomgangatho we-weld. Ukuqonda kunye nokuphucula iiparamitha zenkqubo kunye nedatha ngundoqo ekufezekiseni iziphumo ezilungileyo kwizicelo ezahlukeneyo, okwenza kube bubuchwepheshe obuyimfuneko kwimveliso yanamhlanje.

Nceda uqaphele ukuba eli nqaku libonelela ngokubanzi malunga ne-mid-frequency ngqo yangoku ye-welding yendawo. Ngezicelo ezithile kunye nezikhokelo ezineenkcukacha, jonga iingcebiso zomenzi kunye nemigangatho yoshishino efanelekileyo.
