Lintlha tsa Ts'ebetso ea Ts'ebetso ea Maqhubu a Bohareng ba Hona Joale ea Spot Welding

Spot welding ke ts'ebetso ea bohlokoa ea ho kopanya e sebelisoang haholo liindastering tse fapaneng, ho tloha ho tlhahiso ea likoloi ho isa tlhahisong ea lisebelisoa tsa elektroniki. Lilemong tsa morao tjena, ho tjheseletsa sebakeng se mahareng ha kgau ya kgafetsa ka kotloloho ho atile haholo ka lebaka la ho nepahala le bokgoni ba yona. Sehloohong sena, re hlahlobisisa lintlha tsa bohlokoa tsa mokhoa ona o tsoetseng pele oa ho cheselletsa, ho hlahloba ts'ebetso ea ona, melemo le data ea ts'ebeliso.

Ho utloisisa Mid-Frequency Direct Current Spot Welding

Mid-frequency direct current (MFDC) spot welding ke mokhoa o khethehileng oa ho tjheseletsa o sebelisang motlakase o otlolohileng sebakeng sa maqhubu a mahareng, hangata lipakeng tsa 1000 Hz le 100 kHz. Ho fapana le tjheseletso ea matheba ea AC, MFDC e sebelisa sesebelisoa sa motlakase se thehiloeng ho inverter, se fanang ka melemo e mengata e fapaneng.

Melemo ea MFDC Spot Welding

1. Taolo e ntlafetseng: MFDC welding e fana ka taolo e nepahetseng holim'a weld ea hona joale le nako, e lebisang ho li-welds tse tsitsitseng le tsa boleng bo phahameng.
2. Ho Fokotsa Tšebeliso ea Matla: Tšebeliso ea hona joale e tobileng e fella ka phetisetso ea matla e sebetsang haholoanyane, e lebisang ho fokotseng tšebeliso ea matla ha e bapisoa le welding ea AC.
3. Boleng bo ntlafetseng ba Weld: MFDC welding e fokotsa mefuta e fapaneng ea ho hlahisa mocheso, e fokotsa menyetla ea ho ba le bokooa bo kang ho chesa kapa ho fokola.
4. Eketsa Bophelo ba Electrode: Ka lebaka la ho fokotseha ha li-electrode, welding ea MFDC e ka eketsa bophelo ba li-electrode haholo, e fokotsa nako ea ho phomola bakeng sa tlhokomelo.

Ts'ebetso ea Parameters le Data

Ho ntlafatsa ts'ebetso ea welding ea MFDC, ho tlameha ho nahanoa lintlha tse 'maloa tsa bohlokoa le lintlha tsa data:

1. Weld Current: Palo ea hona joale e fetang ka li-electrode nakong ea welding e ama matla le boleng ba weld. Ka tloaelo e lekantsoeng ka li-kilomperes (kA), hona joale weld e loketseng e ipapisitse le lisebelisoa tse kopantsoeng.
2. Nako ea Weld: Nako ea ho phalla ha joale, e lekantsoeng ka milliseconds (ms), ke parameter e 'ngoe ea bohlokoa. E tlameha ho laoloa ka nepo ho netefatsa hore ho na le weld e matla le e tsitsitseng.
3. Matla a Electrode: Matla a sebelisoang ke li-electrode ho li-workpieces a susumetsa boleng ba weld. E lekanngoa ka li-kilonewtons (kN).
4. Lisebelisoa tsa Electrode: Khetho ea lisebelisoa tsa electrode e ama ho roala ha li-electrode, ka lebaka leo, nako ea tlhokomelo.
5. Kemiso ea Welding: Motsoako oa hona joale oa weld, nako, le electrode force e atisa ho bitsoa "lenaneo la ho cheselletsa." Lisebelisoa tse fapaneng le lits'ebetso li hloka linako tse ikhethileng tsa welding bakeng sa liphetho tse nepahetseng.

Likopo tsa MFDC Spot Welding

Welding ea hona joale ea li-Mid-frequency direct current e fumana ts'ebetso ho liindasteri tse fapaneng:

1. Ho Etsa Likoloi: E sebelisetsoa ho kopanya likarolo tsa 'mele oa koloi, ho netefatsa botšepehi ba sebopeho le polokeho.
2. Tsa elektroniki: E loketse ho kopanya likarolo tsa motlakase ho liboto tsa potoloho tse hatisitsoeng, ho boloka conductivity le ho tšepahala.
3. Sepakapaka: E sebelisetsoa ho cheselletsa likarolo tsa bohlokoa moo ho nepahetseng le manonyeletso a boleng bo holimo a leng bohlokoa.
4. Lisebelisoa: E netefatsa likhokahano tse tšoarellang lisebelisoa tsa lapeng, e ntlafatsa bophelo ba sehlahisoa.

Qetellong, ho tjheseletsa ha libaka ho fana ka monyetla o moholo mabapi le ho nepahala, ho sebetsa hantle le boleng ba weld. Ho utloisisa le ho ntlafatsa maemo a ts'ebetso le data ke senotlolo sa ho fihlela litholoana tse ntle lits'ebetsong tse fapaneng, ho etsa hore e be theknoloji ea bohlokoa haholo tlhahisong ea sejoale-joale.

Ka kopo elelloa hore sengoloa sena se fana ka kakaretso ea kakaretso ea li-welding tsa hona joale tsa sebaka sa mahareng. Bakeng sa lits'ebetso tse ikhethileng le litataiso tse felletseng, sheba likhothaletso tsa moetsi le maemo a amehang a indasteri.
