Ukulayishwa kwangaphambili kunye nokubamba ngamanyathelo abalulekileyo ekusebenzeni koomatshini be-welding ye-medium frequency inverter spot. Ezi ndlela zisetyenziselwa ukuqinisekisa uqhagamshelwano olufanelekileyo phakathi kwee-electrodes kunye ne-workpieces, kunye nokugcina uxinzelelo olufunekayo ngexesha lenkqubo ye-welding. Eli nqaku libonelela ngesishwankathelo sokulayishwa kwangaphambili kunye nokubamba kwi-medium frequency inverter spot welding machines.
- Ukulayishwa kwangaphambili: Ukulayishwa kwangaphambili kubhekiselele kusetyenziso lokuqala loxinzelelo kwizinto zokusebenza ngaphambi kokuba kusetyenziswe umsinga wokuwelda. Isebenza iinjongo ezininzi, kuquka:
- Ukuqinisekisa uqhagamshelwano olufanelekileyo lwe-electrode-to-workpiece ngokususa naziphi na izikhewu zomoya okanye izitenxo kumphezulu.
- Ukuzinzisa ama-workpieces kunye nokuthintela ukunyakaza ngexesha le-welding.
- Ukunciphisa ukuchasana kwi-interface yoqhagamshelwano, okukhokelela ekuphuculeni ukuhamba kwangoku kunye nokuveliswa kobushushu.
- Ukubamba: Ukubamba, okwakwaziwa ngokuba yi-post-welding pressure, kukugcinwa koxinzelelo kwi-workpieces emva kokuba i-welding current icinyiwe. Ivumela ixesha elaneleyo le-weld nugget yokuqinisa kunye nokwenza ibhondi eyomeleleyo. Imiba ephambili yokubamba ibandakanya:
- Ukusebenzisa uxinzelelo olulawulwayo kunye noluhambelanayo kwindawo ye-weld.
- Ukuthintela ukwahlulwa kwangaphambi kwexesha kwezixhobo zokusebenza phambi kokuba i-weld yomelele.
- Ukuvumela ukuchithwa kobushushu okwaneleyo ukunciphisa ukuphazamiseka okanye ukufudumala.
- Ukubaluleka kokuLayisha kwangaphambili kunye nokubamba: Ukulayishwa kwangaphambili kunye nokubamba kubalulekile ekufezekiseni i-welds yendawo ekumgangatho ophezulu. Banikezela ngezi ncedo zilandelayo:
- Ukomelezwa kokuqina kwe-weld kunye nokuphindaphinda ngokuqinisekisa uxinzelelo olufanayo kunye noqhagamshelwano lwe-electrode.
- Ukuhanjiswa kobushushu obuphuculweyo kunye nokudibanisa phakathi kwezinto zokusebenza.
- Ukwakheka okuncitshisiweyo kweziphene, ezifana ne-voids okanye ukungena okungaphelelanga.
- Ukonyuka kwamandla adibeneyo kunye nokuqina.
- Ukulayishwa kwangaphambili kunye neendlela zokubamba: Iindlela ezahlukeneyo zingasetyenziselwa ukulayishwa kwangaphambili kunye nokubamba, kuxhomekeke kwiimfuno ezithile zesicelo se-welding. Ezinye iindlela eziqhelekileyo ziquka:
- Iinkqubo zeMechanical spring-loaded ezibonelela ngoxinzelelo oluqhubekayo kulo lonke umjikelezo we-welding.
- Iinkqubo ze-Pneumatic okanye i-hydraulic ezinokuthi zitshintshwe ukuze zinike uxinzelelo oluchanekileyo kunye noluqhubekayo.
- Iisistim zolawulo ezicwangcisiweyo ezivumela ukulayisha kwangaphambili kunye nokubamba ulandelelwano olusekwe kwizinto zokusebenza kunye nobukhulu.
Ukulayishwa kwangaphambili kunye nokubamba ngamanyathelo abalulekileyo ekusebenzeni koomatshini bokuwelda bamabala aphakathi amaza. Baqinisekisa uqhagamshelwano olufanelekileyo lwe-electrode-to-workpiece, ukuzinzisa i-workpieces ngexesha le-welding, kunye negalelo ekubunjweni kwee-welds ezinamandla kunye nezihambelanayo. Ngokuqonda ukubaluleka kokulayishwa kwangaphambili kunye nokubamba kunye nokusetyenziswa kobuchule obufanelekileyo, abaqhubi banokuphucula umgangatho, ukuthembeka, kunye nokusebenza kwee-welds zendawo kwizicelo ezahlukeneyo zemizi-mveliso.
