Munzvimbo yekugadzira nekubatanidza, spot welding inoita basa rakakosha mukugadzira hukama hwakasimba uye hwakavimbika pakati pezvikamu zvesimbi. Chinhu chakakosha chemichina yewelding ndiyo nut electrode inoshandiswa mukati me-frequency spot welding. Ichi chinyorwa chinotarisa mukati mezvimiro zve nut electrode, ichiratidza kukosha kwayo mukuita welding.
- Mhedziso yeMid-Frequency Spot Welding
Mid-frequency spot welding inomira senzira inochinja-chinja yekubatanidza simbi zvikamu mumaindasitiri kubva kumotokari kusvika kumhepo. Chinhu chayo chinosiyanisa kushandiswa kwepakati-frequency ikozvino inowira pakati pezvakajairwa pasi-frequency uye high-frequency currents. Iyi nzira inovimbisa kuenzana pakati pemhando ye weld uye kugona kwesimba.
- Basa reNut Electrode
Iyo nut electrode, chinhu chakakosha chepakati-frequency spot welding michina, inobatsira zvakanyanya kune welding process. Inoshanda sechibatanidza, ichifambisa kuyerera kwezvino kune workpiece. Iyo nut electrode yakagadzirirwa kubata nati uye workpiece pamwechete zvakasimba, kuve nechokwadi kurongeka kwakaringana panguva yewelding.
- Kuumbwa Kwemaitiro
Chimiro che nut electrode igadziriro yakanyatsogadzirwa iyo inogonesa kuita kwayo. Kazhinji inoumbwa nezvinhu zvinotevera:
a. Electrode Cap: Ichi ndicho chikamu chepamusoro che nut electrode inosangana yakanangana neiyo workpiece. Inowanzo gadzirwa kubva kune yakasimba uye inodzivirira kupisa kuti imirire iyo welding maitiro ekupisa uye mechanical stress.
b. Nut Holder: Iri pazasi pe electrode cap, chibatiso che nzungu chakagadzirirwa kuchengetedza nut panzvimbo. Inovimbisa kuti nati inoramba yakamira panguva yewelding, kudzivirira chero kusarongeka kunogona kukanganisa kunaka kweweld.
c. Shank: Shank inoshanda sekubatana pakati pe nut electrode uye welding muchina. Icho chikamu chakakosha chinotakura welding ikozvino kubva kumushini kuenda kune electrode cap. Iyo shank inogadzirwa kubva kune conductive material ine yakakwira yekupisa conductivity kuderedza kurasikirwa kwesimba.
- Mazano Akakosha Ekugadzira
Kugadzira inoshanda nati electrode inoda kunyatsotariswa kwezvinhu zvakasiyana siyana:
a. Material Selection: Sarudzo yezvishandiso zve electrode cap, nut holder, uye shank zvinokanganisa zvakanyanya kusimba kwe electrode, kupisa kupisa, uye conductivity. Zvinhu zvakajairika zvinosanganisira alloys emhangura uye refractory simbi.
b. Thermal Management: Kushanda kupisa kupisa kwakakosha kudzivirira kupisa kweiyo electrode zvikamu. Nzira dzakakwana dzekutonhodza, dzakadai sekutenderera kwemvura, dzinowanzobatanidzwa mukugadzirwa kwe electrode.
c. Alignment Mechanism: Magadzirirwo emubati we nzungu anofanira kuona kurongeka kwakaringana pakati pe nati neworkpiece, kudzivirira chero kufamba kunogona kukonzera kusaenzana kana kukanganisa weld.
Munzvimbo yepakati-frequency spot welding, iyo nut electrode inomira sechinhu chakakosha asi chinowanzo furatirwa. Chimiro chayo chakaomesesa uye dhizaini ine kufunga inopesvedzera zvakanyanya kushanda kwewelding uye kunaka kweyekupedzisira welds. Sezvo maindasitiri achiramba achida kubatanidza kwakasimba uye kwakavimbika, kunzwisisa uye kukwenenzvera chimiro che nut electrode chicharamba chakakoshera kuwana anowirirana uye emhando yepamusoro welds.
