Munzvimbo ye nut spot welding machines, kuumbwa kwe weld spots inzira yakakosha inotaridza kusimba uye kuvimbika kwejoinhi. Kunzwisisa kuomesesa kweiyi nzira yekugadzira kwakakosha kuti uwane emhando yepamusoro welds mumashandisirwo akasiyana. Ichi chinyorwa chinoongorora nhanho-ne-nhanho maitiro ekuti weld spots anogadzirwa sei mu nut spot welding machines.
- Kugadzirira Kwepamusoro: Usati watanga basa rekushongedza, nzvimbo dzezvishandiso uye nzungu dzinofanirwa kunyatsocheneswa kubvisa chero zvinosvibisa kana oxide layer. Izvi zvinogonesa kuwirirana kwesimbi-kune-simbi, iyo yakakosha pakuwana yakasimba uye yakasimba weld joint.
- Electrode Contact: Sezvo nut spot welding muchina unoita activate, maelectrodes anobata neworkpiece nenzungu. Iko kushandiswa kwekumanikidza kunogonesa kugadzwa kwekubatana kwemagetsi uye kunotanga kuyerera kweiyo welding ikozvino.
- Joule Heating: Kuyerera kweiyo welding ikozvino kuburikidza ne electrode uye workpiece inoburitsa Joule kudziyisa panzvimbo yekubata. Izvi zvinokonzeresa kunyungudika kwenzvimbo kwesimbi pachiratidziro, zvichigadzira dziva rekunyungudutsa.
- Kugovera Kupisa: Munguva yewelding process, kugovera kupisa kunoita basa rakakosha mukudzora saizi nekudzika kwenzvimbo yeweld. Kugovera kupisa kwakakodzera kunovimbisa kuti simbi yakanyungudutswa inopinda mukati mezvishandiso uye nati zvinobudirira, ichigadzira yakasimba metallurgical bond.
- Solidification: Sezvo iko kupera kwewelding, simbi yakanyungudutswa inokurumidza kutonhora nekuoma, kusanganisa workpiece nenzungu pamwechete. Iyo solidification process inokanganisa ma mechanic properties ye weld spot, kusanganisira kusimba kwayo nekuoma kwayo.
- Anealing Effect: Mune dzimwe nguva, weld spot inogona kuita annealing effect, apo nzvimbo yakakanganiswa nekupisa inosangana nekudzora kutonhodza kuti ibvise kushushikana kwasara uye kugadzirisa hukama hwejoinhi.
- Kuongorora Hunhu: Mushure mekuita welding, nzvimbo dze weld dziri pasi pekuomesesa kwemhando yekuongorora kuti ive nechokwadi chekutevedzera zvinodiwa uye zviyero. Akasiyana-siyana asiri ekuparadza ekuyedza matekiniki anogona kushandiswa kuongorora weld kutendeseka.
Magadzirirwo enzvimbo dzeweld mumichina yekugadzira nut spot welding isimba rinopindirana remagetsi azvino, kugadzirwa kwekupisa, uye metallurgical fusion. Kuburikidza nekugadzirisa kwepamusoro pekugadzirira, kunyatso shandiswa kwewelding ikozvino, uye kugovera kwakakodzera kwekupisa, nzvimbo dzepamusoro-soro dze weld dzinowanikwa, zvichibatsira kusimba rose uye kushanda kwemajoini akaiswa. Kunzwisisa uye kugadzirisa iyi nzira yekugadzira kwakakosha pakuona kuvimbika uye hupenyu hurefu hwezvinhu zvakashongedzwa mumaindasitiri akasiyana siyana.
