Deformation chinhu chinowanzo netsa mu nut spot welding, sezvo zvinhu zvakakandwa zvinogona kuita shanduko dzisingadiwe panguva yekuita. Nekudaro, nekushandisa maitiro anoshanda uye nekutevera akanakisa maitiro, zvinokwanisika kudzikisira uye kudzivirira deformation mu nut spot welding. Ichi chinyorwa chinoongorora nzira dzakasiyana dzekuwana kukanganisa-isina welds uye kuchengetedza kurongeka kwemaitiro ezvishandiso.
- Yakakodzera Welding Sequence: Kuti udzivise deformation, zvakakosha kumisikidza yakanyatsorongwa welding kutevedzana. Tanga welding kubva pakati uye kufambira mberi kunze, uchibvumira kutonhora zvishoma nezvishoma uye kushushikana kugovera mukati mese workpiece.
- Kusarudzwa Kwezvinhu: Kusarudza zvinhu zvine zvinoenderana nemafuta ekuwedzera coefficients zvinogona kubatsira kudzikisa njodzi ye deformation. Dzivisa welding zvinhu zvakasiyana zvine zvimiro zvakasiyana zvakanyanya kuchengetedza kufanana panguva yekudziya uye kutonhora.
- Optimal Welding Parameters: Calibrate iyo welding paramita zvichienderana nehupamhi hwezvinhu uye dhizaini yekubatana. Kuve nechokwadi chekuenderana uye kwakakodzera ikozvino, nguva, uye kudzvanywa kuchabatsira kuwana yakaringana kupisa kugovera uye kuderedza kukanganisa.
- Workpiece Fixturing: Kugadzirisa kwakaringana uye clamping kwakakosha kuchengetedza workpiece kugadzikana panguva yewelding. Bata zvakachengetedzeka zvikamu munzvimbo kuti udzivise kufamba uye kukanganisa panguva yekugadzira welding.
- Preheating: Mune zvimwe zviitiko, preheating iyo workpiece inogona kubatsira. Preheating inobatsira kudzikisa tembiricha gradient pakati penzvimbo yeweld uye yakatenderedza zvinhu, nekudaro kuderedza kupisa kwekushisa uye deformation.
- Welding Speed: Kudzora kumhanya kwewelding kwakakosha mukudzivirira deformation. Kumhanya kwakaringana uye kwakatsiga welding inobvumira kupinza kupisa kwakafanana uye kunoderedza njodzi yekupisa kwenzvimbo.
- Post-Weld Heat Treatment: Funga post-weld kupisa kurapwa kuti ubvise kushushikana kwasara uye kuwedzera kudzikamisa iyo welded joint, iyo inogona kubatsira kudzivirira deformation nekufamba kwenguva.
- Kudzora Kutonhodza: Shandisa nzira dzakadzorwa dzekutonhodza kuderedza njodzi yekukurumidza kutonhora-induced deformation. Kutonhora kunononoka uye kwakafanana kunogona kuwanikwa nekushandisa insulating zvinhu kana tembiricha-inodzorwa nharaunda.
Kudzivirira deformation mu nut spot welding inoda nzira yakazara iyo inosanganisira kusarudzwa kwezvinhu, kugadzirisa kwakaringana, optimal welding parameters, uye nzira dzakadzorwa dzekutonhodza. Nekuomerera kune yakanyatsorongeka welding kutevedzana uye kufunga preheating kana post-weld kupisa kurapwa kana zvichidikanwa, vashandisi vanogona kuderedza kushushikana kwekushisa uye kuwana kukanganisa-isina welds. Kushandisa maitiro aya hakuzovi nechokwadi chehutano hwemajoini akasungirirwa asiwo kuchengetedza kutendeseka kwemaitiro ezvikamu, zvichiita kuti zvive zvakakodzera kune zvakasiyana-siyana zvekushandisa.
