Ishintsha Kanjani Ingcindezi Ngesikhathi Se-Mid-Frequency Spot Welding?

I-Mid-frequency spot welding, eyaziwa nangokuthi i-medium-frequency resistance welding, iyindlela esetshenziswa kakhulu ezimbonini ezihlukahlukene zokuhlanganisa izingxenye zensimbi.Ngesikhathi senqubo yokushisela, amapharamitha amaningana adlala indima ebalulekile ekunqumeni ikhwalithi ye-weld.Enye yale mingcele ingcindezi esetshenzisiwe, enomthelela omkhulu enqubweni yokushisela kanye namandla ahlangene aphumela.Kulesi sihloko, sizohlola ukuthi ingcindezi ishintsha kanjani phakathi ne-mid-frequency spot welding kanye nemiphumela yayo kwikhwalithi yokushisela.

Ingcindezi iyipharamitha ebalulekile ngesikhathi sokushisela, njengoba ithonya ukuxhumana phakathi kwezinto zokusebenza nama-electrode, ngaleyo ndlela kuthinte ukukhiqizwa kokushisa nokugeleza kwezinto.Phakathi kwe-frequency spot welding, ingcindezi esetshenziswa phakathi kwama-electrode nezinto zokusebenza iba nezinguquko ezithile kuwo wonke umjikelezo wokushisela.

1. Othintana naye Wokuqala: Njengoba ama-electrode esondela ezintweni zokusebenza, ingcindezi iqala ukwanda.Lokhu kucindezela kokuqala kokuxhumana kuqinisekisa ukuqhutshwa kahle kukagesi kanye nokukhiqizwa kokushisa okufanele endaweni esibonakalayo yokushisela.
2. Isigaba Sokucindezela: Uma ama-electrode ethintana nezinto zokusebenza, ingcindezi iyaqhubeka nokukhuphuka njengoba ama-electrode ecindezela izinto ndawonye.Lesi sigaba sokucindezela sibalulekile ekusunguleni indawo yokuxhumana efanayo kanye nokunciphisa noma yiziphi izikhala zomoya ezingase zithinte ikhwalithi yokushisela.
3. Uhlelo lokusebenza lwamanje lwe-Welding: Njengoba i-welding current isetshenziswa, ukumelana nesixhumi esibonakalayo kukhiqiza ukushisa, okuholela ekuncibilikeni kwezinto zendawo.Phakathi nalesi sigaba, ingcindezi ingase yehle kancane ngenxa yokuthambisa kwezinto kanye nokwakheka kwe-nugget encibilikisiwe.
4. Bamba Isigaba: Ngemuva kokuthi i-welding current ivaliwe, ingcindezi igcinwa isikhathi esifushane phakathi nesigaba sokubamba.Lesi sigaba sivumela into encibilikisiwe ukuthi iqine futhi yakhe inhlanganisela ye-weld eqinile.Ukucindezela kuqinisekisa ukuthi ukuqina kwenzeka ngokuhambisana kahle, ukunciphisa ukuhlanekezela.
5. Isigaba sokupholisa: Njengoba ijoyinti le-weld liphola, ingcindezi ingakhululwa kancane kancane.Kodwa-ke, izinga elithile lokucindezela lingase lisetshenziswe ukuvimbela noma yikuphi ukugoqa noma ukuhlanekezela okubangelwa ukupholisa okusheshayo.

Ukwehluka kwengcindezi phakathi nenqubo yokushisela amabala amaphakathi nefrequency kuthinta ngokuqondile ikhwalithi yokushisela nobuqotho.Ukuphathwa kwengcindezi ngendlela efanele kunomthelela kulezi zici ezilandelayo:

1. Ukwakhiwa kwe-Nugget: Ukucindezela okulungile kuqinisekisa ukuthi izinto ezincibilikisiwe zisakazwa ngokufanayo, zakha i-weld nugget eqinile futhi engaguquki.Ukucindezela okunganele kungaholela ekwakhekeni kwe-nugget engalingani kanye namalunga abuthakathaka.
2. I-Porosity Encishisiwe: Ukucindezela okwanele kusiza ekwehliseni ukuba khona kwamaphakethe omoya nama-voids ngaphakathi kwe-weld.Lokhu kungapheleli kungenza buthaka ukujoyina futhi kunciphise amandla ayo okuthwala umthwalo.
3. Ukwehliswa Ukuhlanekezela: Ukulawula ukucindezela phakathi nesigaba sokupholisa kuvimbela ukufinyela okusheshayo kanye nokuhlanekezela okulandelayo kwezingxenye ezishiselwe.
4. Ukwenziwa Kwezinto Ezingcono Kagesi kanye Nezishisayo: Ukucindezela okuhle kakhulu kuthuthukisa ukuxhumana phakathi kwama-electrode nama-workpieces, okuholela ekuthuthukisweni kokusebenza kukagesi nokushisayo, okuholela ekukhiqizeni ukushisa okuphumelelayo.

Emkhakheni we-mid-frequency spot welding, ukushintshashintsha kwengcindezi kudlala indima ebalulekile ekunqumeni ikhwalithi nokuthembeka kwamajoyini wokushisela.Kusukela ekuthinteni kokuqala kuya esigabeni sokupholisa, ukulawula ingcindezi kuqinisekisa ukugeleza kwezinto ezifanele, ukwakheka kwe-nugget, nobuqotho obuhlangene.Abakhiqizi nabasebenza ngokushisela kufanele baqaphe ngokucophelela futhi balawule imingcele yokucindezela ukuze kuzuzwe ukushiselwa okungaguquki kanye nekhwalithi ephezulu, okunomthelela ekupheleleni okuphelele kwesakhiwo sezingxenye ezikhiqiziwe.
