I-Resistance spot welding yindlela esetyenziswa ngokubanzi kwishishini lemveliso yokudibanisa isinyithi.Le nkqubo ixhomekeke kulawulo oluchanekileyo lweeparamitha ezahlukeneyo, enye yazo yi-voltage inter-electrode.Kweli nqaku, siza kuhlolisisa ukubaluleka kokubeka iliso kwi-voltage ye-inter-electrode kumatshini wokuwelda indawo yokumelana kunye nokuba igalelo njani kumgangatho kunye nokusebenza kakuhle kwenkqubo ye-welding.
I-Resistance spot welding bubuchule obubandakanya ukugqithiswa kombane ngokusebenzisa i-electrode ezimbini ukwenza i-weld yendawo, yobushushu obuphezulu phakathi kwamaqhekeza amabini esinyithi.I-electrodes idityaniswe nezinto zokusebenza, kwaye ukuhamba kwangoku kuvelisa ubushushu, kubangela ukuba iintsimbi zinyibilike kwaye zidibanise kunye.Le nkqubo iqhele ukusetyenziswa kwimizi-mveliso yeemoto, i-aerospace, kunye ne-electronics, phakathi kwezinye.
Ukubaluleka kwe-Inter-Electrode Voltage
I-voltage ye-inter-electrode, eyaziwa ngokuba yi-welding voltage, idlala indima ebalulekileyo ekumiseleni umgangatho we-weld.Yi-voltage esetyenziswa phakathi kwee-electrode ezimbini ze-welding ngexesha lenkqubo ye-welding.Ukubeka iliso kulo mbane kubalulekile ngenxa yezizathu ezininzi:
1. Ulawulo loMgangatho weWeld:I-voltage ye-inter-electrode ichaphazela ngokuthe ngqo ukushisa okwenziwa kwindawo ye-weld.Ngokubeka iliso kunye nokulawula lo mbane, abavelisi banokuqinisekisa ukuba i-welds ihlangabezana nemigangatho yomgangatho ofunekayo.Ukwahluka kwi-voltage kunokukhokelela kwi-welds engahambelaniyo, enokubangela ukuba amalungu abuthathaka okanye iziphene.
2. Ukuhambelana kwezinto:Izixhobo ezahlukeneyo zifuna useto oluthile lombane ukwenzela ukuwelda ngokufanelekileyo.Ukubeka iliso kwi-voltage ye-inter-electrode ivumela abaqhubi ukuba bahlengahlengise izicwangciso ezisekelwe kwizinto ezidityanisiweyo, ukuqinisekisa ibhondi ethembekileyo ngaphandle kokonakalisa i-workpieces.
3. Inkqubo eFanelekileyo:Ukugcina i-voltage ye-inter-electrode engaguqukiyo kuphucula ukusebenza kakuhle kwenkqubo ye-welding.Iyanciphisa imfuno yohlengahlengiso lwezandla kunye nokusebenza kwakhona, okukhokelela kwimveliso ephezulu kunye neendleko eziphantsi zemveliso.
4. I-Electrode Wear:Ngokuhamba kwexesha, ii-electrode ziye ziwohloke ngenxa yeemeko ezigqithisileyo zokuwelda.Ukubeka iliso kwi-voltage kunokunceda ekuboneni izitenxo ezinokubonisa ukunxitywa kwe-electrode.Ukufunyaniswa kwangaphambili kuvumela ukutshintshwa ngexesha elifanelekileyo, ukuthintela iziphene kwi-welds.
5. Ukhuseleko:Ukugqithisa kwamandla ombane kunokukhokelela ekufudumeni, okunokuthi kubangele umngcipheko wokhuseleko kwindawo ye-welding.Ukubeka iliso kumbane kunceda ukugcina iimeko zokusebenza ezikhuselekileyo, ukukhusela zombini izixhobo kunye nabasebenzi.
Iindlela zokubeka iliso
Kukho iindlela ezahlukeneyo zokubeka iliso kwi-voltage ye-inter-electrode kwindawo yokumelana nomatshini wokuwelda:
1. Iimitha zombane:Iimitha zombane weDijithali ziqhele ukusetyenziswa ukubonelela ngofundo lwexesha lokwenyani lombane ngexesha lenkqubo yokuwelda.Ezi mitha zinokudityaniswa kwizixhobo zokuwelda ukwenzela ukubeka iliso ngokuqhubekayo.
2. Ukufakwa kwedatha:Abanye oomatshini bokuwelda abakwizinga eliphezulu banesakhono sokungena kwidatha.Babhala idatha ye-voltage ekuhambeni kwexesha, bevumela abaqhubi ukuba bahlalutye iintsingiselo kunye nokwenza uhlengahlengiso njengoko kufuneka.
3. Iialamu kunye nezilumkiso:Oomatshini be-welding banokuxhotyiswa ngee-alamu okanye izilumkiso eziqalisa xa i-voltage idlula okanye iwela ngaphantsi kwe-preset thresholds.Le ngxelo yangoko inceda ukukhusela iziphene ze-welding.
Ukubeka iliso kwi-voltage ye-inter-electrode kwi-resistance spot welding machines ngumba obalulekileyo wokuqinisekisa i-welds ekumgangatho ophezulu, ukukhulisa ukusebenza kakuhle, kunye nokugcina ukhuseleko kwinkqubo ye-welding.Ngokusebenzisa iindlela ezisebenzayo zokujonga amandla ombane, abavelisi banokonyusa ukuthembeka kwee-welds zabo kwaye bafezekise iziphumo ezingaguqukiyo, ezikumgangatho ophezulu kuzo zonke izicelo ezahlukeneyo.
