Nhanganyaya kune Preloading uye Kubata muMedium Frequency Inverter Spot Welding Machines

Preloading uye kubata matanho akakosha mukushanda kwepakati frequency inverter spot welding michina. Aya matekiniki anoshandiswa kuve nechokwadi chekubatana kwakakodzera pakati pee electrode uye workpieces, pamwe nekuchengetedza yaidiwa kudzvanywa panguva yewelding process. Ichi chinyorwa chinopa tarisiro ye preloading uye kubata mukati ma frequency inverter spot welding michina.

1. Preloading: Preloading inoreva kushandiswa kwekutanga kwekumanikidza pane workpieces isati yaiswa welding ikozvino. Inoshanda zvinangwa zvakawanda, kusanganisira:
   • Kuve nechokwadi chekubata kwe electrode-kune-workpiece nekubvisa chero mapeji emhepo kana kusarongeka kwepasi.
   • Kudzikamisa workpieces uye kudzivirira kufamba panguva welding.
   • Kuderedza kushorwa pane yekubatana interface, zvichikonzera kuvandudzwa kwezvino kuyerera uye kupisa chizvarwa.
2. Kubata: Kubata, kunozivikanwawo se-post-welding pressure, ndiko kuchengetedza kwekumanikidza pane workpieces mushure mekunge welding yadzimwa. Inobvumira nguva yakakwana yekuti weld nugget isimbise uye igadzire chisungo chakasimba. Zvinhu zvakakosha zvekubata zvinosanganisira:
   • Kushandisa inodzorwa uye inopindirana kumanikidza kune weld nzvimbo.
   • Kudzivirira kupatsanurwa nguva isati yakwana yezvishandiso zvebasa risati rasimba.
   • Kubvumira kupisa kwakakwana kwekupisa kuderedza kukanganisa kana kupisa.
3. Kukosha kwe Preloading uye Kubata: Preloading uye kubata kwakakosha kuti uwane emhando yepamusoro nzvimbo welds. Vanopa zvinotevera zvakanakira:
   • Yakakwidziridzwa weld kuenderana uye kudzokorora nekuvimbisa yunifomu kudzvanywa uye electrode kubata.
   • Yakavandudzwa kupisa kugovera uye fusion pakati pezvishandiso.
   • Maumbirwo akaderedzwa ehurema, senge voids kana kupinda kusina kukwana.
   • Kuwedzera simba rekubatana uye kusimba.
4. Preloading uye Holding Techniques: Matekinoroji akasiyana anogona kushandiswa kurongedza uye kubata, zvichienderana nezvinodiwa chaizvo zvewelding application. Dzimwe nzira dzakajairika dzinosanganisira:
   • Mechanical chitubu-akaremerwa masisitimu anopa anogara achimanikidza mukati mewelding kutenderera.
   • Pneumatic kana hydraulic masisitimu anogona kugadziridzwa kuti ape chaiyo uye isingachinji kumanikidza.
   • Programmable kudzora masisitimu ayo anobvumira kurongedzerwa kurodha uye kubata kutevedzana kwakavakirwa pane workpiece zvinhu uye ukobvu.

Preloading uye kubata matanho akakosha mukushanda kwepakati frequency inverter spot welding michina. Ivo vanovimbisa yakakodzera electrode-kune-workpiece kusangana, kudzikamisa maworkpiece panguva yewelding, uye kubatsira mukuumbwa kwesimba uye rinoenderana welds. Nekunzwisisa kukosha kwekutanga kurodha uye kubata uye nekushandisa nzira dzakakodzera, vashandisi vanogona kusimudzira mhando, kuvimbika, uye kuita kwema spot welds mune akasiyana maindasitiri maapplication.
