Isingeniso Sokulayisha Ngaphambili nokubamba Emishinini Yokushisela I-Medium Frequency Inverter Spot

Ukulayisha kuqala nokubamba kuyizinyathelo ezibalulekile ekusebenzeni kwemishini yokushisela i-medium frequency inverter spot. Lezi zindlela zisetshenziselwa ukuqinisekisa ukuthintana okufanele phakathi kwama-electrode nama-workpieces, kanye nokugcina ingcindezi oyifunayo ngesikhathi senqubo yokushisela. Lesi sihloko sinikeza ukubuka konke kokulayisha kuqala nokubamba imishini yokushisela indawo ye-inverter ye-medium frequency.

1. Ukulayisha kuqala: Ukulayisha kuqala kubhekisela ekusetshenzisweni kokuqala kwengcindezi ezintweni zokusebenza ngaphambi kokuba kusetshenziswe umsinga wokushisela. Ifeza izinjongo eziningana, okuhlanganisa:
   • Ukuqinisekisa ukuthintana okufanele kwe-electrode-to-workpiece ngokususa noma yiziphi izikhala zomoya noma ukungalungi kwendawo.
   • Ukuzinzisa ama-workpieces nokuvimbela ukunyakaza ngesikhathi sokushisela.
   • Ukunciphisa ukumelana kusixhumi esibonakalayo sokuxhumana, okuholela ekuthuthukisweni kokugeleza kwamanje nokukhiqiza ukushisa.
2. Ukubamba: Ukubamba, okwaziwa nangokuthi i-post-welding pressure, ukugcinwa kwengcindezi kuma-workpieces ngemva kokucisha i-welding current. Ivumela isikhathi esanele sokuthi i-weld nugget iqinise futhi yakhe isibopho esiqinile. Izici ezibalulekile zokubamba zihlanganisa:
   • Ukusebenzisa ingcindezi elawulwayo futhi engaguquki endaweni yokushisela.
   • Ukuvimbela ukuhlukaniswa ngaphambi kwesikhathi kwezingxenye zokusebenza ngaphambi kokuba i-weld iqine.
   • Ukuvumela ukuchithwa kokushisa okwanele ukuze kuncishiswe ukuhlanekezela noma ukushisa ngokweqile.
3. Ukubaluleka kokulayisha kuqala nokubamba: Ukulayisha kuqala nokubamba kubalulekile ukuze kuzuzwe ukushiselwa kwamabala kwekhwalithi ephezulu. Banikeza izinzuzo ezilandelayo:
   • Ukuvumelana kwe-weld okuthuthukisiwe nokuphindaphinda ngokuqinisekisa ingcindezi efanayo kanye nokuxhumana kwe-electrode.
   • Ukusabalalisa ukushisa okuthuthukisiwe kanye nokuhlanganisa phakathi kwezinto zokusebenza.
   • Ukwakheka okuncishisiwe kokukhubazeka, okufana ne-voids noma ukungena okungaphelele.
   • Amandla ahlangene nokuqina.
4. Amasu okulayisha kuqala nokubamba: Amaqhinga ahlukene angasetshenziswa ukulayisha kuqala nokubamba, kuye ngezidingo ezithile zohlelo lokushisela. Ezinye izindlela ezivamile zihlanganisa:
   • Amasistimu we-spring-loaded wemishini ahlinzeka ngengcindezi eqhubekayo kuwo wonke umjikelezo wokushisela.
   • Amasistimu we-pneumatic noma ama-hydraulic angalungiswa ukuze alethe ingcindezi enembile futhi engaguquki.
   • Amasistimu okulawula ahlelekayo avumela ukulayisha kwangaphambilini okwenziwe ngendlela oyifisayo nokubamba ukulandelana okusekelwe ezintweni zokusebenza nogqinsi.

Ukulayisha kuqala nokubamba kuyizinyathelo ezibalulekile ekusebenzeni kwemishini yokushisela i-medium frequency inverter spot. Baqinisekisa ukuthintana okufanele kwe-electrode-to-workpiece, bazinzise ama-workpieces ngesikhathi sokushisela, futhi babambe iqhaza ekwakhiweni kwama-welds aqinile futhi angaguquki. Ngokuqonda ukubaluleka kokulayisha kuqala nokubamba nokusebenzisa amasu afanelekile, opharetha bangathuthukisa ikhwalithi, ukwethembeka, kanye nokusebenza kwama-spot weld ezinhlelweni ezihlukene zezimboni.
