Selelekela sa Resistance ka Medium Frequency Inverter Spot Welding Machines

Resistance e bapala karolo ea bohlokoa ts'ebetsong ea mechini ea welding e mahareng ea frequency inverter spot. Ho utloisisa mohopolo oa ho hanyetsa ho bohlokoa bakeng sa ho fihlela lits'ebetso tse sebetsang hantle le tse sebetsang tsa welding spot. Sengoliloeng sena se fana ka kakaretso ea ho hanyetsa le bohlokoa ba eona ho mechini ea tjheseletsa ea maqhubu a maqhubu a mahareng.

1. Ho utloisisa Resistance: Resistance ke thepa ea thepa e sitisang ho phalla ha motlakase. Boemong ba ho cheselletsa letheba, ho hanyetsa ho bolela khanyetso e kopanang le motlakase ha o feta ka har'a workpiece le li-electrode.
2. Karolo ea Resistance ho Spot Welding: Resistance e bapala likarolo tse 'maloa tsa bohlokoa mochining oa ho tjheseletsa matheba:
   • Moloko oa Mocheso: Ha motlakase o feta ka khanyetso ea mosebetsi, o hlahisa mocheso ka lebaka la phello ea Joule. Mocheso ona o bohlokoa bakeng sa ho qhibiliha le ho kopanya lisebelisoa nakong ea ho cheselletsa letheba.
   • Taolo ea Hona joale: Boleng ba ho hanyetsa bo lekanya palo ea hona joale e phallang ka har'a workpiece. Ka ho laola khanyetso, li-operators li ka laola hona joale oa welding, ho netefatsa ho kenya mocheso o nepahetseng le ho kopanya hantle.
   • Electrode Contact: Ho hanyetsa ho sebopeho sa electrode-workpiece ho ama boleng ba puisano ea motlakase. Khatello e nepahetseng ea li-electrode le boemo ba holim'a metsi li bohlokoa ho fokotsa ho hanyetsa le ho finyella motlakase o motle oa motlakase.
3. Lintlha tse Amang Resistance ho Spot Welding: Lintlha tse 'maloa li susumetsa khanyetso ho tjheseletsa sebakeng:
   • Thepa ea Lintho: Lisebelisoa tse fapaneng li na le litekanyetso tse fapaneng tsa ho hanyetsa. Lisebelisoa tse tsamaisang, tse kang koporo, li na le khanyetso e fokolang, ha lisebelisoa tsa ho sireletsa, tse kang rabara, li na le khanyetso e phahameng.
   • Botenya ba Workpiece: Lisebelisoa tse teteaneng hangata li bonts'a khanyetso e phahameng ka lebaka la tsela e telele ea hajoale.
   • Maemo a Bokaholimo: Libaka tse hloekileng le tse lokiselitsoeng hantle li netefatsa khokahano e ntle ea motlakase, e fokotsang khanyetso.
   • Moralo oa Electrode: Sebopeho, boholo le thepa ea li-electrode li ama khanyetso ho sebopeho sa li-electrode-workpiece.
4. Ho lekola Resistance ho Spot Welding: Ho lekola khanyetso ho ka fana ka maikutlo a bohlokoa nakong ea ts'ebetso ea tjheseletsa. Ka ho lekanya khanyetso, basebetsi ba ka lekola boleng ba weld, ho bona mefokolo e ka bang teng kapa ho fapana, le ho lokisa liparamente tsa welding ka nepo.

Qetello: Ho utloisisa khanyetso le karolo ea eona mochining oa welding oa frequency inverter spot welding ho bohlokoa bakeng sa ho fihlela li-welds tse atlehileng. Ho hanyetsa ha workpiece le electrode interface ho etsa qeto ea ho hlahisa mocheso, phallo ea hona joale, le boleng ba ho kopana le motlakase nakong ea ts'ebetso ea ho tjheseletsa. Ka ho nahana ka lintlha tse kang thepa ea thepa, botenya ba workpiece, maemo a holim'a metsi, le moralo oa li-electrode, basebetsi ba ka laola ka katleho ho hanyetsa le ho ntlafatsa mekhoa ea ho cheselletsa sebaka. Ho beha leihlo khanyetso nakong ea welding ho fana ka leseli la bohlokoa mabapi le boleng ba weld le ho thusa ho lokisa liphetho tse ntlafalitsoeng tsa welding.
