Lutshintsha njani uxinzelelo ngexesha le-Mid-Frequency Spot Welding?

I-Mid-frequency spot welding, ekwabizwa ngokuba yi-medium-frequency resistance welding, bubuchule obusetyenziswa ngokubanzi kumashishini ahlukeneyo okudibanisa amacandelo esinyithi. Ngexesha lenkqubo ye-welding, iiparamitha ezininzi zidlala indima ebalulekileyo ekumiseleni umgangatho we-weld. Enye yale parameters yingcinezelo esetyenzisiweyo, enempembelelo enkulu kwinkqubo ye-welding kunye nesiphumo samandla adibeneyo. Kweli nqaku, siza kuphonononga ukuba uxinzelelo lutshintsha njani ngexesha le-welding ye-mid-frequency spot kunye neziphumo zayo kumgangatho we-weld.

Uxinzelelo luyiparameter ebalulekileyo ngexesha le-welding yendawo, njengoko ichaphazela uqhagamshelwano phakathi kwezinto zokusebenza kunye nee-electrode, ngaloo ndlela ichaphazela ukuveliswa kobushushu kunye nokuhamba kwezinto. Kwi-middle-frequency spot welding, uxinzelelo olusetyenzisiweyo phakathi kwee-electrode kunye neendawo zokusebenza zihamba utshintsho oluthile kumjikelezo we-welding.

1. UQhagamshelwano lokuqala: Njengoko i-electrode isondela kwizinto zokusebenza, uxinzelelo luqala ukunyuka. Olu xinzelelo lokuqala loqhagamshelwano luqinisekisa ukuhanjiswa kombane okulungileyo kunye nokuveliswa kobushushu obufanelekileyo kwi-welding interface.
2. Inqanaba loxinzelelo: Emva kokuba i-electrodes idibanisa kunye nezixhobo zokusebenza, uxinzelelo luqhubeka lukhuphuka njengoko i-electrodes icinezela izinto kunye. Esi sigaba soxinzelelo sibalulekile ekusekeni indawo yoqhagamshelwano efanayo kunye nokunciphisa naziphi na izikhewu zomoya ezinokuchaphazela umgangatho we-weld.
3. Ukuwelda usetyenziso lwangoku: Njengoko i-welding current isetyenziswa, ukuchasana kwi-interface kuvelisa ukushisa, okukhokelela ekunyibilikeni kwezinto zendawo. Ngethuba lesi sigaba, uxinzelelo lunokufumana ukuhla okuncinci ngenxa yokuthotywa kwezinto kunye nokwakhiwa kwe-nugget etyhidiweyo.
4. Bamba iSigaba: Emva kokuba i-welding current ivaliwe, uxinzelelo lugcinwa ixesha elifutshane ngexesha lokubamba isigaba. Esi sigaba sivumela izinto ezityhidiweyo ukuba ziqine kwaye zenze i-weld joint eqinile. Uxinzelelo luqinisekisa ukuba ukuqina kwenzeka ngolungelelwaniso olufanelekileyo, ukunciphisa ukuphazamiseka.
5. Isigaba sokupholisa: Njengoko i-weld joint iphola phantsi, uxinzelelo lunokukhululwa ngokuthe ngcembe. Nangona kunjalo, umgangatho othile woxinzelelo usenokusetyenziswa ukuthintela nakuphi na ukujika okanye ukugqwethwa okubangelwa kukupholisa ngokukhawuleza.

Ukwahluka koxinzelelo ngexesha lenkqubo ye-welding ye-mid-frequency spot ichaphazela ngokuthe ngqo umgangatho we-weld kunye nokunyaniseka. Ulawulo olululo loxinzelelo lunegalelo kule miba ilandelayo:

1. Nugget Formation: Uxinzelelo oluchanekileyo luqinisekisa ukuba izinto ezityhidiweyo zihanjiswa ngokufanayo, zenza i-weld nugget eqinile kwaye ehambelanayo. Uxinzelelo olunganelanga lunokukhokelela ekubunjweni kwe-nugget engalinganiyo kunye namalungu abuthathaka.
2. UkuNcitshiswa kwePorosity: Uxinzelelo olwaneleyo lunceda ekunciphiseni ubukho beepokotho zomoya kunye ne-voids ngaphakathi kwe-weld. Ezi ziphene zingenza buthathaka umdibaniso kunye nokunciphisa umthamo walo wokuthwala umthwalo.
3. UkuNcitshiswa kokuGqwetha: Ukulawula uxinzelelo ngexesha lesigaba sokupholisa kuthintela ukunqanyulwa ngokukhawuleza kunye nokuphazamiseka okulandelayo kwamacandelo adibeneyo.
4. Ukuphuculwa koMbane kunye neThermal Conductivity: Uxinzelelo oluphezulu luphucula uqhagamshelwano phakathi kwe-electrodes kunye ne-workpieces, ekhokelela ekuphuculeni umbane kunye ne-thermal conductivity, okukhokelela ekuveliseni ukushisa okusebenzayo.

Kwindawo ye-mid-frequency spot welding, ukuhluka koxinzelelo kudlala indima ebalulekileyo ekumiseleni umgangatho kunye nokuthembeka kwamalungu e-weld. Ukususela ekudibaneni kokuqala ukuya kwisigaba sokupholisa, ukulawula uxinzelelo kuqinisekisa ukuhamba kwezinto ezifanelekileyo, ukubunjwa kwe-nugget, kunye nokunyaniseka ngokubambisana. Abavelisi kunye nabaqhubi be-welding kufuneka babeke iliso ngononophelo kwaye balawule iiparitha zoxinzelelo ukuze bafezekise i-welds ehambelanayo kunye nekhwalithi ephezulu, igalelo kwintembeko yolwakhiwo ngokubanzi lwamacandelo enziweyo.
