Ingabe Yamanje kanye ne-Voltage Kuthinta Ukusebenza Kwe-Resistance Spot Welding?

I-Resistance spot welding iyinqubo yokujoyina esetshenziswa kakhulu ezimbonini ezahlukahlukene, ikakhulukazi ekwenziweni kwezimoto kanye ne-aerospace.Le nqubo ihilela ukusebenzisa amandla kagesi kanye nokucindezela ukudala izibopho eziqinile phakathi kwamashidi ensimbi noma izingxenye.Isici esisodwa esibalulekile esivame ukuphakamisa imibuzo indima yamanje kanye ne-voltage ekunqumeni ikhwalithi nokusebenza ngempumelelo kwama-spot weld.Kulesi sihloko, sizohlola umthelela wezilungiselelo zamanje kanye ne-voltage ku-resistance spot welding.

Ukuqonda Resistance Spot Welding

Ngaphambi kokungena ethonyeni lamanje kanye ne-voltage, kubalulekile ukubamba izisekelo ze-resistance spot welding.Kule nqubo, izindawo ezimbili zensimbi ziyahlangana futhi zingaphansi kwamandla kagesi aphezulu.Lokhu kwamanje kugeleza ensimbi futhi kukhiqize ukushisa ngenxa yokumelana kwayo.Ukushisa kuncibilikisa ingxenye encane yensimbi, kwakheka i-nugget encibilikisiwe epholile futhi iqine ukuze yakhe i-weld.

Iqhaza Lamanje

Isimo samanje se-resistance spot welding sidlala indima ebalulekile ekunqumeni ikhwalithi ye-weld.Kuthinta izinga lokushisa, usayizi we-nugget, namandla ebhondi esewonke.Nansi indlela:

1. Izinga Lokushisa:Amaleveli aphezulu amanje aholela ekushiseni okushesha kakhulu.Lokhu kungaba wusizo ezintweni ezizacile njengoba kunciphisa ukunqanyulwa kokushisa futhi kubangele indawo encane ethinteke ukushisa.Kodwa-ke, ezintweni eziwugqinsi, amandla amaningi kakhulu angase abangele ukusha noma ukuphalaza.
2. Usayizi we-Nugget:Okwamanje kunomthelela kusayizi we-nugget encibilikisiwe eyenziwe ngesikhathi sokushisela.Amazinga aphezulu amanje avame ukudala ama-nuggets amakhulu.Usayizi we-nugget ubalulekile ngoba uthinta ngokuqondile amandla elunga.Amandla anganele angaholela kuma-nuggets abuthakathaka, amancane, okufaka engozini ubuqotho be-weld.
3. Amandla ebhondi:Ikhwalithi ye-weld isondelene ne-current.Amaleveli amanje alungiswe kahle aqinisekisa ukushisela okuqinile nokuqina.Ukuchezuka ebangeni lamanje elinconyiwe kungaholela kumabhondi abuthaka nokuncipha kobuqotho besakhiwo.

Iqhaza le-Voltage

I-Voltage, ngokuhlangana neyamanje, idlala indima ehambisanayo ekushiseleleni indawo yokumelana:

1. Ukuqaliswa kwe-Arc:I-Voltage inesibopho sokuqalisa i-arc phakathi kwe-electrode ne-workpiece.Kudingeka kwanele ukunqoba ukumelana nesixhumi esibonakalayo se-electrode-workpiece.I-voltage ephansi ingase ibangele ama-arcs angazinzile kanye nekhwalithi yokushisela engeyinhle.
2. Ukulawulwa kwe-Weld Pool:I-voltage iphinda ithinte ukwakheka nokusimama kwe-weld pool.Isiza ukulawula ukugeleza kwensimbi encibilikisiwe futhi iqinisekisa ukusatshalaliswa okufanayo, ivimbela ukungahambi kahle kobuhlalu obushiselayo.

Ukuthuthukisa yamanje kanye ne-Voltage

Ukuze kuzuzwe ukushiselwa kwendawo yokumelana nekhwalithi ephezulu, kubalulekile ukukhulisa kokubili izilungiselelo zamanje kanye nezamandla kagesi.Lokhu kuhilela ukucabangela izici ezinjengokuqina kwempahla, uhlobo lwensimbi, nomklamo we-electrode.Abakhiqizi bavame ukunikeza imihlahlandlela yokushisela kanye nezincomo zezinto ezithile kanye nezicelo.

Sengiphetha, i-current kanye ne-voltage yimingcele ebalulekile ekushiseni kwendawo yokumelana.Ukulungisa kahle lezi zilungiselelo kubalulekile ukuze kukhiqizwe amashisela athembekile futhi aqinile.Ukuchezuka kumanani anconyiwe kungaholela ekulimaleni, ekwehliseni amandla ebhondi, kanye nokwehluleka kwesakhiwo okungaba khona.Ngakho-ke, ukuqonda ubudlelwano phakathi kwemiphumela yamanje, i-voltage, kanye ne-welding kubalulekile ukuze kuqinisekiswe ukusebenza kahle kwezinqubo zokushisela endaweni yokumelana ezimbonini ezahlukahlukene.
