Isingeniso Setemu Lokushisela Emishinini Yokushisela Imvamisa Emaphakathi

Lesi sihloko sinikeza isingeniso kumagama okushisela asetshenziswa emishinini yokushisela i-medium frequency inverter spot. Ukuqonda le migomo kubalulekile kochwepheshe abasebenza nale mishini ukuze baxhumane ngempumelelo, baxazulule izinkinga, futhi balungiselele izinqubo zokushisela. Lesi sihloko sihlose ukujwayeza abafundi ngamagama asemqoka okushisela kanye nezincazelo zabo kumongo we-medium frequency inverter spot welding.

1. I-Welding Yamanje: I-Welding current ibhekisela ekugelezeni kwamandla kagesi ngokusebenzisa isifunda sokushisela ngesikhathi senqubo yokushisela. Kuwuhlaka olubalulekile olunquma ukushisa okukhiqizwa ku-weld interface futhi luthinte ikhwalithi namandla e-weld. I-welding current ivamise ukukalwa ngama-ampere (A) futhi ingalungiswa ukuze kuzuzwe izici zokushisela ezifiselekayo.
2. I-Electrode Force: I-Electrode force, eyaziwa nangokuthi ingcindezi yokushisela, ingcindezi esetshenziswa ama-electrode kuzinto zokusebenza ngesikhathi sokushisela. Kubalulekile ukusungula ukuthintana kukagesi okufanele kanye nokuqinisekisa ukukhiqizwa kokushisa okusebenzayo endaweni yokushisela. Amandla e-Electrode ngokuvamile akalwa ngama-newtons (N) futhi kufanele alungiswe ngokusekelwe kubukhulu bezinto ezibonakalayo nezimfuneko zokushisela.
3. Isikhathi sokushisela: Isikhathi sokushisela sibhekisela esikhathini lapho i-welding current isetshenziswa khona ezintweni zokusebenza. Idlala indima ebalulekile ekulawuleni okokufaka ukushisa, ukujula kokungena, kanye nekhwalithi yokushisela iyonke. Isikhathi sokushisela ngokuvamile silinganiswa ngama-millisecond (ms) noma imijikelezo futhi singalungiswa ukuze kuzuzwe izici ezifiselekayo zokushisela.
4. Amandla Welding: Amandla okushisela yinani eliphelele lokufaka ukushisa ezintweni zokusebenza ngesikhathi senqubo yokushisela. Ibalwa ngokuphindaphinda i-welding current ngesikhathi se-welding. Amandla e-welding athonya ukwakheka kwe-weld nugget, ukuhlanganiswa, namandla e-weld jikelele. Ukulawula kahle amandla okushisela kubalulekile ekuzuzeni ama-welds angaguquki futhi athembekile.
5. I-Welding Cycle: Umjikelezo wokushisela ubhekisela ekulandeleni okuphelele kokusebenza okudingekayo ukuze kwakhiwe i-weld eyodwa. Ngokuvamile kufaka phakathi ukwehla kwe-electrode, ukuthintana nokubamba kwe-electrode, ukugeleza kwamanje, isikhathi sokupholisa, kanye nokuhoxiswa kwe-electrode. Ukuqonda nokwenza kahle amapharamitha womjikelezo wokushisela kubalulekile ukuze kuzuzwe ikhwalithi yokushisela oyifunayo kanye nokusebenza kahle kwesikhathi somjikelezo.
6. I-Electrode Life: Impilo ye-Electrode ibhekisela esikhathini lapho ama-electrode angagcina izici zawo zokusebenza nokusebenza. Ngesikhathi sokushisela, ama-electrode angaphansi kokuguga nokonakala ngenxa yezinto ezinjengokushisa, ingcindezi, kanye ne-arcing kagesi. Ukuqapha nokuphatha impilo ye-electrode kubalulekile ukuze kuqinisekiswe ikhwalithi yokushisela engaguquki futhi ugweme isikhathi sokuphumula esingadingekile sokushintshwa kwama-electrode.

Isiphetho: Ukujwayelana namagama okushisela kubalulekile ekusebenzeni ngempumelelo nemishini yokushisela i-medium frequency inverter spot. Ukuqonda ukusebenza kwe-welding yamanje, amandla e-electrode, isikhathi sokushisela, amandla okushisela, umjikelezo wokushisela, nempilo ye-electrode kwenza ochwepheshe bakwazi ukuthuthukisa izinqubo zokushisela, ukuxazulula izinkinga, nokuqinisekisa ikhwalithi ye-weld engaguquki. Ukufunda okuqhubekayo kanye nokusetshenziswa kwamatemu okushisela kunomthelela ekwazisweni okuphelele nasekuphumeleleni kwezicelo zokushisela amabala amabala ohlobo lwe-inverter.
