Isingeniso Sesimiso Somshini Wokushisela We-Medium Frequency DC Spot

I-Medium frequency DC spot welding iyinqubo yokushisela esebenza kahle kakhulu futhi esetshenziswa kabanzi ethola izinhlelo zokusebenza kuzo zonke izimboni ezihlukahlukene, ezihlanganisa ezezimoto, i-aerospace, ne-electronics. Kulesi sihloko, sizocubungula imigomo eyisisekelo ekhona kulobu buchwepheshe.

Izisekelo ze-Medium Frequency DC Spot Welding

I-Medium frequency DC spot welding iyindlela ekhethekile yokushisela ehlanganisa ukuhlanganiswa kwezingcezu ezimbili zensimbi ngokusebenzisa intambo kagesi ukuze kuncibilike indawo endaweni lapho okuxhunywana khona. Lokhu kubangela ukwakheka kwesibopho esiqinile phakathi kwezinto zokwakha, okwenza kube inqubo ebalulekile ekukhiqizeni.

Isimiso Sokusebenza

Izingxenye eziyinhloko zomshini wokushisela amabala we-DC imvamisa emaphakathi zifaka umthombo wamandla, ama-electrode, kanye neyunithi yokulawula. Nansi indlela inqubo esebenza ngayo:

1. Umthombo wamandla: Umthombo wamandla ukhiqiza i-direct current (DC) kumafrikhwensi aphakathi nendawo, ngokuvamile ebangeni lika-1000 kuya ku-100,000 Hz. Le frikhwensi ephakathi ibalulekile ukuze kuzuzwe imiphumela emihle, njengoba ifinyelela ukulingana phakathi kokungena kanye nokukhiqiza ukushisa.
2. Ama-Electrodes: Ama-electrode amabili, ngokuvamile enziwe ngethusi noma ama-alloys ethusi, asetshenziselwa ukuqhuba okwamanje kuma-workpieces. Lawa ma-electrode aklanyelwe ukugxilisa amandla kagesi endaweni yokushisela, ukuqinisekisa isibopho esiqinile.
3. Xhumana kanye Welding: Ama-workpieces aboshwe phakathi kwama-electrode, okwenza indawo yokuxhumana eqinile. Uma i-current isetshenziswa, i-arc enezinga eliphezulu lokushisa iyakhiqizwa kule ndawo yokuxhumana. Ukushisa okunamandla kuncibilikisa izindawo zokusebenza, ezibe sezihlangana ndawonye njengoba zipholile, zenze i-weld.
4. Iyunithi yokulawula: Iyunithi yokulawula ilawula inqubo yokushisela ngokulawula amapharamitha afana namanje, isikhathi sokushisela, nokucindezela. Lokhu kulawula okunembile kuqinisekisa ukuvumelana kanye nekhwalithi kuma-welds.

Izinzuzo ze-Medium Frequency DC Spot Welding

I-Medium frequency DC spot welding inikeza izinzuzo ezimbalwa:

• Ikhwalithi ephezulu ye-Weld: Inqubo elawulwayo iphumela ekushiseleni okuqinile nokuthembekile, okubalulekile ezinhlelweni zokusebenza lapho ukuphepha nobuqotho kubaluleke kakhulu.
• Ukusebenza kahle: I-Medium frequency welding iyonga amandla ngenxa yokulawula kwayo okunembayo, inciphisa ukulahlekelwa ukushisa kanye nokusetshenziswa kwamandla.
• Ukuguquguquka: Ingakwazi ukushisela izinhlobonhlobo zezinsimbi nama-alloys, iyenze ifanele izimboni ezihlukahlukene.
• Isivinini: Inqubo ishesha kakhulu, iyenza ifanele imigqa yokukhiqiza yevolumu ephezulu.

I-Medium frequency DC spot welding iyindlela eguquguqukayo nesebenzayo yokuhlanganisa izinsimbi ezinhlelweni ezihlukene zezimboni. Ukuqonda izimiso zayo ezibalulekile kubalulekile ukuze kuzuzwe ukushiselwa kwekhwalithi ephezulu nokuthembekile, okunikela ekukhiqizweni kwemikhiqizo ephephile nehlala isikhathi eside kuzo zonke izimboni eziningi.
