Mofuthu oa Mocheso le Lintho tse Susumetsang Mechineng ea Welding ea Resistance Spot

Resistance spot welding ke mokhoa o sebelisoang haholo ho kopanya liindasteri tse fapaneng, ho kenyeletsoa tlhahiso ea likoloi, sefofane le lisebelisoa tsa elektroniki. Nakong ea ts'ebetso ea welding, mocheso o hlahisoa ka mokhoa o ke keng oa qojoa, 'me tlhahiso ena ea mocheso e ka ama haholo boleng le botšepehi ba weld. Sehloohong sena, re tla hlahloba mekhoa ea ho hlahisa mocheso mecheng ea ho hanyetsa le ho hlahloba lintlha tsa bohlokoa tse susumetsang tlhahiso ena ea mocheso.

Mekhoa ea ho Hlahisa Mocheso

Ho tjheseletsa sebakeng sa ho hanyetsa, lisebelisoa tse peli kapa ho feta tsa tšepe li kopantsoe hammoho ka ho sebelisa khatello le ho fetisa motlakase o phahameng libakeng tsa ho kopana. Mocheso o hlahisoa haholo-holo ka lebaka la mekhoa e latelang:

  1. Resistance Heating: Ha motlakase o ntse o phalla ka har'a likotoana tsa tšepe, ho hanyetsa ha thepa ho hlahisa mocheso. Mocheso ona o lekana ka ho toba le khanyetso ea lisebelisoa le sekwere sa hona joale se fetang ho tsona, joalokaha ho hlalositsoe ke molao oa Joule.
  2. Ikopanye le Resistance: Ho hanyetsa ho kopana pakeng tsa electrode le workpiece ho boetse ho tlatsetsa ho hlahisa mocheso. E angoa ke boemo bo holimo, bohloeki, le khatello e sebelisoang sebakeng sa ho kopana.
  3. Ho lahleheloa ke Hysteresis: Ka thepa ea ferromagnetic, joalo ka tšepe, tahlehelo ea hysteresis e hlaha ka lebaka la liphetoho tse potlakileng tsa matla a matla a khoheli a hlahisoang ke hona joale. Tahlehelo ena e fella ka tlhahiso e eketsehileng ea mocheso.

Lintho Tse Susumetsang

Mabaka a 'maloa a ka susumetsa bongata ba mocheso o hlahisoang ho tjheseletsa sebakeng sa resistance:

  1. Welding Current: Ho eketsa mocheso oa motlakase ho tla lebisa ho moloko o phahameng oa mocheso ka lebaka la kamano e tobileng pakeng tsa hona joale le mocheso.
  2. Matla a Electrode: Matla a phahameng a electrode a ka eketsa tlhahiso ea mocheso ka ho ntlafatsa ho kopana pakeng tsa li-electrode le li-workpieces.
  3. Lisebelisoa tsa Electrode: Khetho ea lisebelisoa tsa elektrode e ka ama haholo ho hlahisa mocheso. Li-electrode tse entsoeng ka thepa e nang le khanyetso e phahameng ea motlakase, joalo ka koporo, li atisa ho hlahisa mocheso o mongata.
  4. Lisebelisoa tsa Workpiece: Ho hanyetsa motlakase oa lisebelisoa tsa mosebetsi ho phetha karolo ea bohlokoa ho hlahisa mocheso. Lisebelisoa tse nang le khanyetso e phahameng, joalo ka tšepe e sa hloekang, li hlahisa mocheso o mongata ho feta lisebelisoa tse nang le khanyetso e tlase, joalo ka aluminium.
  5. Nako ea ho Welding: Linako tse telele tsa ho tjheseletsa li ka lebisa tlhahisong e eketsehileng ea mocheso kaha mocheso o na le nako e ngata ea ho bokella sebopeho sa weld.
  6. Electrode Tip Geometry: Sebopeho le boemo ba malebela a electrode li ama khanyetso ea ho kopana, e leng eona e susumetsang tlhahiso ea mocheso.

Ho tjheseletsa sebakeng sa ho hanyetsa, ho utloisisa mekhoa ea ho hlahisa mocheso le lintlha tse o susumetsang ke habohlokoa bakeng sa ho finyella li-welds tsa boleng bo phahameng. Ka ho laola ka hloko li-parameter tse kang ho cheselletsa hona joale, matla a electrode, le khetho ea thepa, bahlahisi ba ka ntlafatsa ts'ebetso ea welding ho hlahisa manonyeletso a matla le a ka tšeptjoang ha ba ntse ba fokotsa monyetla oa ho ba le bokooa bo bakoang ke mocheso o feteletseng. Tsebo ena e kenya letsoho katlehong e akaretsang le katleho ea ho tjheseletsa letheba la ho hanyetsa lits'ebetsong tse fapaneng tsa indasteri.
