Ho Fuputsa Malebela a ho Sebelisa Mechini ea Welding ea Resistance Spot

Resistance spot welding ke mokhoa oa bohlokoa indastering ea tlhahiso le ea tšepe. Mokhoa ona o kopanya likotoana tsa tšepe ka ho sebelisa khatello le mocheso, ho theha maqhama a matla le a ka tšeptjoang. Ho fumana liphetho tse ntle le ho netefatsa polokeho, ho bohlokoa ho tseba ts'ebetso ea mochini oa tjheseletsa sebakeng sa resistant spot. Sehloohong sena, re tla hlahloba malebela le mekhoa ea bohlokoa ea ho sebelisa mochini ona ka nepo.

1. Tšireletseho PelePele re ikakhela ka setotsoana ts'ebetsong ea mechini ea ho tjheseletsa sebakeng sa resistance, ho bohlokoa ho beha polokeho pele. Kamehla u roale thepa e loketseng ea ho itšireletsa (PPE), ho kenyeletsoa liatlana, likhalase tsa tšireletso le liaparo tse sa cheng. Netefatsa hore sebaka seo u sebeletsang ho sona se na le moea o motle oa moea ho qhala mosi o hlahisoang nakong ea ho cheselletsa.
2. Tlhophiso ea MochiniQala ka ho hlahloba mochini oa ho cheselletsa ho etsa bonnete ba hore o maemong a nepahetseng a ho sebetsa. Sheba li-electrode hore na ha li senyehile kapa li senyehile, 'me u li khutlisetse ha ho hlokahala. Fetola matla a electrode le welding ea hona joale ho latela botenya ba thepa le mofuta oo u o tjhesang. Sheba bukana ea mochini bakeng sa litlhophiso tse khethehileng.
3. Tokisetso ea LinthoLokisetsa lisebelisoa tse tla chesetsoa ka ho li hloekisa le ho li tlotsa. Tšilafalo efe kapa efe e ka holim'a metsi e ka ama boleng ba weld. Netefatsa hore likotoana tsa tšepe li hokahantsoe hantle 'me li ts'oaroe li tiile ho sebelisoa li-clamp kapa li-fixtures.
4. Electrode PlacementHo beha li-electrode ka nepo ho bohlokoa bakeng sa weld e atlehileng. Beha li-electrode perpendicular ho lisebelisoa tse kopantsoeng 'me u netefatse hore li kopana hantle. Ho se tsamaisane hantle kapa ho kopana le li-electrode tse sa lokelang ho ka fella ka li-welds tse fokolang.
5. Mokhoa oa ho WeldingTs'ebetso ea welding e kenyelletsa ho hatella li-electrode khahlano le lisebelisoa le ho fetisa motlakase o phahameng ho tsona ka nako e itseng. Boloka khatello e tsitsitseng 'me u laole nako ea ho tjheseletsa ho etsa nugget e ts'oanang le e matla ea weld. Nako e loketseng ea tjheseletsa le litlhophiso tsa hona joale li tla itšetleha ka botenya ba thepa le mofuta.
6. Ho phodisaKa mor'a ho cheselletsa, lumella sebaka se cheselitsoeng hore se pholile ka tlhaho kapa se sebelise mokhoa o pholileng o khothalletsoang bakeng sa thepa. Ho pholisa ka potlako ho ka lebisa ho petsoha kapa liphoso tse ling ho weld.
7. Hlahloba le TekoKamehla hlahloba weld bakeng sa boleng. Sheba matšoao leha e le afe a sekoli, a kang mapetsong, li-voids, kapa mekhoa e sa tšoaneng. Haeba ho hlokahala, etsa mekhoa ea tlhahlobo e sa senyeheng, joalo ka tlhahlobo ea ho kenella ka dae kapa tlhahlobo ea X-ray, ho netefatsa bots'epehi ba weld.
8. TlhokomeloKamehla boloka mochini oa hau oa tjheseletsa oa sebaka sa ho hanyetsa ho o boloka o le maemong a nepahetseng. Hloekisa li-electrode, hlahloba hore na ha li senyehile, 'me u tlotse likarolo tse tsamaeang joalo ka ha moetsi a khothalelitse. Mochine o hlokometsoeng hantle o tiisa li-welds tse tsitsitseng le tsa boleng bo phahameng.

Qetellong, ho tseba ts'ebetso ea mochini oa tjheseletsa sebakeng sa ho hanyetsa ho hloka ho ela hloko lintlha le boitlamo ba polokeho. Ka ho latela malebela le mekhoa ena, u ka etsa li-welds tse matla le tse ka tšeptjoang ha u ntse u netefatsa sebaka se sireletsehileng sa ho sebetsa. Hopola ho sheba bukana ea tataiso ea mochini le ho batla koetliso haeba u sa tsoa qala ho bona tjheseletso ho holisa tsebo ea hau ts'ebetsong ena ea bohlokoa ea tlhahiso.
