Abstract: Ama-Medium frequency inverter spot welders asetshenziswa kakhulu ezimbonini ezahlukahlukene ngokusebenza kahle kwawo okuphezulu kanye nekhwalithi enhle yokushisela.Nokho, ukuqonda inqubo yokushisela le mishini kungaba inselele.Kulesi sihloko, sizoxoxa ngenqubo ye-welding ye-medium frequency inverter spot welders kusuka emibonweni emibili ehlukene, kuhlanganise nombono kagesi kanye nombono oshisayo.
Isingeniso:
Ama-welder e-Medium frequency inverter spot welder asetshenziswa kakhulu embonini yokukhiqiza ngokusebenza kahle kwawo okuphezulu kanye nekhwalithi enhle yokushisela.Nokho, inqubo yokushisela yale mishini ingaba yinkimbinkimbi futhi ibe inselele ukuyiqonda.Kulesi sihloko, sizohlola inqubo ye-welding ye-medium frequency inverter spot welders kusuka emibonweni emibili ehlukene, umbono kagesi kanye nombono oshisayo.
Ukubuka kukagesi:
Inqubo yokushisela ye-medium frequency inverter spot welder incike kakhulu ezintweni zikagesi zomshini.I-welder ikhiqiza i-high frequency current edluliswa ngama-electrodes welding kanye ne-workpiece.I-current igeleza ku-workpiece, ikhiqiza ukushisa futhi yenza i-weld.Inqubo yokushisela ingahlukaniswa ngezigaba ezintathu: isiteji sokuminyanisa, isiteji sokushisela, kanye nesiteji sokubamba.
Esigabeni sokuminyanisa, ama-electrode wokushisela afaka ingcindezi ku-workpiece, ewaxhumanisa.Lesi sigaba sibalulekile njengoba siqinisekisa ukuthi i-workpiece ibekwe kahle futhi ibanjwe endaweni ngesikhathi senqubo yokushisela.
Esigabeni se-welding, i-high frequency current idlula kuma-electrode kanye ne-workpiece, ikhiqiza ukushisa futhi incibilikisa i-workpiece.Ukushisa kukhiqizwa ngenxa yokumelana kwe-workpiece ekugelezeni kwamanje.I-current isetshenziselwa isikhathi esithile futhi ngamandla athile ukuze kuqinisekiswe ukuncibilika okufanele nokushisela.
Esigabeni sokubamba, i-current ivaliwe, kodwa ama-electrode welding ayaqhubeka nokufaka ukucindezela ku-workpiece.Lesi sigaba sivumela i-weld ukuthi iphole futhi iqinise, iqinisekise ukushisela okuqinile futhi okuqinile.
I-Thermal Perspective:
Inqubo yokushisela ye-medium frequency inverter spot welder iphinde ithonywe izici ezishisayo.Ukushisa okukhiqizwa ngesikhathi sokushisela kulawulwa yizici ezihlukahlukene, okuhlanganisa okwamanje, ingcindezi ye-electrode, nesikhathi sokushisela.
Phakathi nenqubo yokushisela, ukushisa okukhiqizwa yi-current kubangela ukuthi i-workpiece yande futhi inkontileka.Ukwandiswa okushisayo kanye nokufinyezwa kwe-workpiece kungathinta ikhwalithi ye-weld futhi kuholele ekuhlanekeni noma ekuqhekekeni.
Ukuze uvimbele lezi zinkinga, imingcele ye-welding kufanele ilawulwe ngokucophelela ukuze kuqinisekiswe inani elifanele lokushisa elikhiqizwayo futhi lisetshenziswe ku-workpiece.Ukwengeza, ukusetshenziswa kwamanzi okupholisa kanye nokugcinwa okufanele kwe-electrode kungasiza ukulawula ukushisa okukhiqizwa ngesikhathi sokushisela futhi kuvimbele ukushisisa kwama-electrode.
Isiphetho:
Sengiphetha, inqubo yokushisela yama-medium frequency inverter spot welder iyinkimbinkimbi futhi ingaba inselele ukuyiqonda.Ngokuhlola inqubo ngokubuka kokubili kukagesi nokushisa, singathola ukuqonda okungcono kwezinto ezithonya ikhwalithi ye-weld.Ukulawulwa okufanele kwemingcele yokushisela nokugcinwa kwemishini kubalulekile ukuze kuqinisekiswe ama-welds asezingeni eliphezulu futhi aqinile.
