Medium-frequency direct current spot welding machines anoshandiswa zvakanyanya mumaindasitiri akasiyana ekubatanidza masimbi masimbi pamwechete. Michina iyi inoita basa rakakosha mukuona kusimba uye kusimba kwezvigadzirwa zvakawanda, kubva kuzvinhu zvemotokari kuenda kumidziyo yemumba. Kuti tinzwisise zvirinani kuti michina iyi inoshanda sei, ngationgororei matanho akakosha mukushanda kwavo.
- Magetsi: Nhanho yekutanga mukushanda kwepakati-frequency yakananga ikozvino nzvimbo welding muchina inosanganisira kupa iyo ine yakagadzikana magetsi. Kazhinji, michina iyi inoda yakananga ikozvino (DC) sosi yemagetsi, inogona kupihwa nenzira dzakasiyana siyana, kusanganisira matransformer uye anogadzirisa. Simba remagetsi rinofanirwa kunyatsogadziriswa kuti ive nechokwadi cheiyo voltage uye mazinga aripo eiyo welding process.
- Clamping: Kana magetsi agadzwa, zvikamu zvesimbi zvinobatanidzwa zvinosungirirwa zvakachengeteka panzvimbo. Iri inhanho yakakosha, sezvo kurongeka kwakakodzera uye kudzvanywa kwakakosha pakuwana yakasimba uye yakavimbika weld. Mimwe michina inoshandisa machira emagetsi, nepo mamwe anoshandisa pneumatic kana hydraulic masisitimu kubata zvikamu pamwechete.
- Electrode Contact: Danho rinotevera rinosanganisira kuunza ma electrode welding kuti abatane nenhengo dzesimbi kuti dzive welded. Aya maelectrode anowanzo kuve nemhangura kana zvimwe zvinhu zvinoitisa uye akagadzirirwa kuendesa magetsi emagetsi kune maworkpieces. Yakakodzera electrode dhizaini uye kurongeka kwakakosha pakuwana mhando weld.
- Welding Yazvino Chikumbiro: Nema electrode panzvimbo, muchina welding unoshandisa yakakwira ikozvino, kazhinji muchimiro cheiyo yakananga ikozvino (DC), kune yekusangana mapoinzi pakati pezvikamu zvesimbi. Parizvino iyi inoburitsa kupisa kwakanyanya, zvichiita kuti simbi dzinyunguduke uye dzibatane pamwechete. Nguva uye kusimba kwekuyerera kwezvino zvinonyatsodzorwa kugadzira chisungo chakasimba uye chakasimba pasina kupisa kana kukuvadza zvinhu.
- Kutonhodza uye Solidification: Mushure mekunge welding ikozvino yaiswa, muchina wacho unowanzo sanganisira inotonhorera system kuti ikurumidze kutonhora nzvimbo yakashongedzwa. Izvi zvinobatsira kuomesa simbi yakanyungudutswa uye kuderedza kuumbwa kwezvakaremara kana nzvimbo dzisina simba mu weld. Kutonhodza kwakafanira kwakakosha pakuwana chepamusoro-soro, structural sound weld.
- Quality Control: Pakupedzisira, gungano rakasungirirwa rinoiswa pasi pekuongororwa kwehutano kuti ive nechokwadi chokuti weld inosangana nemitemo yakatarwa. Izvi zvinogona kusanganisira kuongorora kwekuona, kuyedza kusingaparadze, kana dzimwe nzira dzekuona kuremara, kutsemuka, kana kusarongeka mune weld. Chero nyaya dzinogadziriswa kuti ive nechokwadi chekuti chigadzirwa chekupedzisira chinosangana nemhando yaunoda uye kuita zvinodiwa.
Mukupedzisa, yepakati-frequency yakananga ikozvino nzvimbo welding muchina unotevera akatevedzana akakosha matanho ekubatanidza simbi zvikamu zvinobudirira. Kubva pakugadzirisa magetsi akagadzikana kusvika pakuisa welding ikozvino uye kuitisa macheki ekutonga kwemhando, nhanho imwe neimwe inoita basa rakakosha mukugadzira mawelds akasimba uye akavimbika. Kunzwisisa maitiro ekushanda aya kwakakosha kune avo vanobatanidzwa mukugadzira simbi uye maindasitiri ekugadzira.
