Emishinini yokushisela indawo yokushisela i-frequency inverter, ukusetshenziswa kwengcindezi kuyisinyathelo esibalulekile enqubweni yokushisela. Ingcindezi esetshenziswa phakathi kwama-electrode nezinto zokusebenza ithonya ikhwalithi namandla ejoyinti lokushisela. Lesi sihloko sidingida izigaba ezihilelekile kwinqubo yokufaka isicelo sokucindezela emishinini yokushisela i-medium frequency inverter spot welding.
- Isigaba Sokuqala Sokuxhumana: Isigaba sokuqala sokufakwa kwengcindezi ukuxhumana kokuqala phakathi kwama-electrode nezinto zokusebenza:
- Ama-electrode ahlanganiswa nezinto zokusebenza, ukuqinisekisa ukuqondana okufanele nokuma.
- Ingcindezi yokuqala elula isetshenziswa ukuze kutholwe ukuthintana kukagesi futhi kususwe noma yikuphi ukungcola okungaphezulu noma izendlalelo ze-oxide.
- I-Pre-Compression Stage: Isigaba sangaphambi kokucindezelwa sibandakanya ukukhulisa kancane kancane ingcindezi esetshenzisiwe:
- Ukucindezela kukhuphuka kancane kancane ukuze kufinyelele izinga elanele lokushisela okusebenzayo.
- Lesi sigaba siqinisekisa ukuthintana okufanele kwe-electrode-to-workpiece futhi silungiselela izinto zenqubo yokushisela.
- Isiteji sangaphambi kokucindezelwa sisiza ukuqeda noma yiziphi izikhala zomoya noma ukungalungi phakathi kwama-electrode nezinto zokusebenza, ukuqinisekisa ukushisela okungaguquki.
- Isiteji sokushisela: Lapho ingcindezi oyifunayo isifinyelelwe, isigaba sokushisela siqala:
- Ama-electrode anengcindezi engaguquki futhi elawulwayo kuma-workpieces kuyo yonke inqubo yokushisela.
- I-welding current isetshenziswa, ikhiqiza ukushisa kusixhumi esibonakalayo se-electrode-to-workpiece, okuholela ekuncibilikeni kwendawo kanye nokwakheka kwe-weld okwalandela.
- Isiteji sokushisela ngokuvamile sinesikhathi esinqunyiwe esisekelwe kumingcele yokushisela kanye nezidingo zezinto ezibonakalayo.
- I-Post-Compression Stage: Ngemuva kwesiteji sokushisela, isigaba sokucindezela siyalandela:
- Ukucindezela kugcinwa isikhathi esifushane ukuvumela ukuqina nokupholisa kwejoyinti le-weld.
- Lesi sigaba sisiza ukuqinisekisa ukuhlanganiswa okufanele nokuhlanganiswa kwensimbi encibilikisiwe, okuthuthukisa amandla nobuqotho be-weld.
Uhlelo lokusebenza lwengcindezi emishinini yokushisela i-medium frequency inverter spot welding lubandakanya izigaba ezimbalwa, ngasinye sisebenzisa inhloso ethile enqubweni yokushisela. Isigaba sokuqala sokuxhumana sisungula ukuthintana kwe-electrode-to-workpiece, kuyilapho isigaba sangaphambi kokucindezelwa siqinisekisa ukuqondanisa okufanele futhi sisuse izikhala zomoya. Isiteji sokushisela sisebenzisa ingcindezi engaguquki ngenkathi i-welding current ikhiqiza ukushisa ukuze kusungulwe i-weld. Ekugcineni, isiteji se-post-compression sivumela ukuqina nokupholisa kwe-weld joint. Ukuqonda nokusebenzisa kahle isigaba ngasinye sohlelo lokusebenza lwengcindezi kubalulekile ukuze kuzuzwe amashisela ekhwalithi ephezulu anamandla afanele nobuqotho emishinini yokushisela imvamisa emaphakathi.
