Ukubambelela kwi-Electrode kuhlala kungumngeni oqhubekayo kwimisebenzi yokuvelisa, kubangela ukuphazamiseka kwemveliso, ukunyuka kwexesha lokunciphisa, kunye nokunciphisa umgangatho we-weld. Amaziko amaninzi ajongene nelahleko enkulu yezoqoqosho kulo mba, eyona nto isuka kulawulo olungafanelekanga lweparameter ye-welding. Ukuvela kwamaza aphakathiumatshini wokuwelda indawoiteknoloji inikeza isisombululo esisebenzayo kule ngxaki kudala.
Izizathu eziphambili zokuBamba i-Electrode
1.Imiba yokuguquguquka kwangoku
- Izixhobo zoomatshini bokuwelda bemveli zisebenzisa amandla ombane we-AC ongunothi wangoku -ukunqumla okudala ukufudumeza okungalinganiyo. Itekhnoloji yomatshini we-welding we-Medium frequency spot isebenzisa ukulungiswa kunye nokuguqulwa ukuze kugcinwe i-stable current kwi-800-2000Hz, ukunciphisa kakhulu umngcipheko wokubambelela ngokunikezelwa ngokuchanekileyo ngoku.
2.Uxinzelelo lwe-Electrode olunganelanga
- Uxinzelelo olungazinzanga lukwandisa ukuchasana koqhagamshelwano, okukhokelela ekugqithiseni kwendawo kunye nokubambelela. Umatshini we-welding we-medium frequency spot welding ubandakanya iinkqubo zokulawula uxinzelelo ezithi zilungelelanise ngokuguquguqukayo ukuya kumanqanaba afanelekileyo, ziqinisekisa ujongano lwe-welding efanayo kunye nokunciphisa izehlo ezincamathelayo ngaphezulu kwe-60%.
3.Ungcoliseko loMphezulu kunye ne-Electrode Wear
- I-oyile ye-workpiece, i-oxidation layers, kunye nokonakala kwezinto ze-electrode zenza iingxaki zokuncamathela zibe mandundu. Umatshini wokuwelda indawo oqhelekileyo usebenzisa imveliso ye-DC egxininisa ubushushu kwindawo ye-weld, ukunciphisa ukutshiza kunye neziphumo zosulelo. Iimpawu zayo zokuphendula ngokukhawuleza (i-millisecond{2}}inqanaba lokulawula inqanaba) lithintela ukunamathela kwesinyithi esinyibilikisiweyo kwi-electrode.
Izinto eziluncedo kwezobuGcisa kwiTekhnoloji yeFrequency ePhakathi
I-frequency ephakathiumatshini wokuwelda indawoinika izibonelelo ezibalulekileyo ngezakhono zolawulo eziphuculweyo:
- Ukuchaneka kommiselo wangoku kuphuculwe nge-80x xa kuthelekiswa nezixhobo eziqhelekileyo
- Ukuchaneka kwexesha lokuwelda ukuya kuthi ga kwi-0.25ms kuthintela ukunamathela okugqithisileyo{1}}okunyanzeliswa
- Abavelisi becandelo lezithuthi banika ingxelo kufutshane{0}}nokupheliswa kokuncamathelwa kwe-electrode
- Ukuchaneka kwemveliso kunyuka ngama-25% okuxhaphake ukuzuzwa
- Ubomi benkonzo ye-electrode eyandisiweyo kunciphisa ukuphindaphinda kokutshintshwa
IziKhokelo zokuKhetha kunye nokuPhunyezwa
Xa ukhetha umatshini wokuwelda amabala aphakathi, beka phambili:
- Uzinzo lwemetrics yokusebenza yangoku
- Amandla ohlengahlengiso loxinzelelo kunye namaxesha okuphendula
- Ukusebenza kwenkqubo yokupholisa kunye nokuthembeka
- Isigaba sesithathu -esilungelelanisiweyo sokuhambelana kwegalelo
Ngowona matshini wokuwelda amaza omoya aphakathi:
- Sebenzisa iiprothokholi zokucoca umphezulu we-electrode rhoqo
- Yenza ulungelelwaniso lweparamitha ngamaxesha
- Ukubekwa esweni kwezalathi zenkqubo yokusebenza
- Izibonelelo zinika ingxelo yokunciphisa izehlo ukusuka kwi-30% ukuya ngaphantsi kwe-5%.
IziCwangciso zokuThintela zokuLondoloza
Yandisa utyalo-mali lwakho lomatshini we-welding ophakathi nendawo ngokusebenzisa:
- Ukuhlolwa kwe-electrode ecwangcisiweyo kunye nemijikelezo yokugqoka
- Ukugcinwa kwenkqubo yokupholisa kunye nolawulo lomgangatho wamanzi
- Ukuqinisekiswa rhoqo kwenkqubo yokulawula ukuchaneka
- Uqeqesho lomsebenzisi ekusebenzeni ngendlela eyiyo kwezixhobo
- Amaxwebhu eeparameters ezifanelekileyo kwizixhobo ezahlukeneyo
Ukuqukumbela
Ukuncamathela kwe-Electrode kwizicelo zoomatshini bokuwelda ayisiyongxaki engenakuphepheka kodwa ngumngeni onokusonjululwa ngokuphunyezwa kwetekhnoloji ephezulu. Umatshini wokuwelda amabala aphakathi, kunye nemveliso yawo yangoku ezinzileyo, amandla okulawula achanekileyo, kunye neempawu zokuphendula ezisebenzayo, uye waba ngumgangatho woshishino wokuphelisa imiba yokubambelela.
Utyalo-mali kwitekhnoloji yomatshini we-welding we-frequency ephakathi ayinciphisi nje ilahleko yexesha eliphantsi kodwa ikwanyusa umgangatho wemveliso kunye nokusebenza kakuhle kokwenziwa. Kumashishini alandela ukugqwesa kwemveliso ephezulu, amaza aphakathiumatshini wokuwelda indawoimele izixhobo ezibalulekileyo zokunciphisa amazinga okusilela kunye nokuphumeza iinjongo zemveliso ebhityileyo.
