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.
