Munyika yewelding, kurongeka kwakakosha. Resistance spot welding hazvisi izvo. Chimwe chinhu chakakosha chinowanzoitika chisingatarisirwi asi chine basa rakakosha mukuwana emhando yepamusoro welds inguva yekufanorodha. Muchinyorwa chino, isu tichaongorora kukosha kwe preloading nguva muresitorendi nzvimbo welding michina.
Understandi
Resistance spot welding, nzira inoshandiswa zvakanyanya yekujoinha mumotokari, aerospace, uye maindasitiri ekugadzira, inosanganisira kusanganisa masimbi maviri pamwe chete uchishandisa kupikisa kwemagetsi uye kumanikidza. Kuwana yakasimba, yakasimba weld inotsamira pakudzora akasiyana ma paramita, paine preloading nguva iri imwe yeanonyanya kukosha.
Chii chinonzi Preloading Time?
Preloading nguva, mumamiriro ekupikisa nzvimbo welding, inoreva nguva iyo ma electrode anotsikirirwa pamwe chete nesimba risati rashandiswa welding ikozvino. Inguva iyo mashizha maviri esimbi anosangana, uye iyo chaiyo welding process inotanga.
Sei Preloading Nguva Yakakosha?
- Material Contact: Kurodha kwakakodzera kunovimbisa kuti mapepa esimbi akabatana akazara. Kubata uku kwekutanga kwakakosha nekuti chero mapundu kana kusarongeka kunogona kutungamira kune asina kusimba welds kana kunyange weld hurema. Simba rinoshandiswa panguva yekutakura rinobatsira kubvisa kusakwana kwakadaro.
- Thermal Control: Preloading nguva inobatsirawo mukudzora kupisa kwekutanga kunogadzirwa kana welding ikozvino yaiswa. Kana iyo yazvino yatangwa isati yatanga kurodha, kupisa kwakanyanya kunogona kukanganisa maworkpiece kana kugadzira zvisingadiwe kupisa zvinokanganisa, zvichikanganisa kunaka kweweld.
- Kuenderana: Consistency ndiyo kiyi mukupikisa nzvimbo welding. Nekuva nenguva yakatsanangurwa yekurodha, vashandisi vanogona kudzokorora mamiriro akafanana kune ese weld, kuve nechokwadi chekufanana uye kuvimbika mukuita kwekugadzira.
- Electrode Wear: Kusakwana preloading kunogona kukurumidza kupfeka electrode. Simba rinoshandiswa panguva yekurodha rinobatsira kuchengetedza kunaka kwemagetsi pakati pema electrode uye maworkpieces, kuderedza kusakara uye kuwedzera hupenyu hwemagetsi.
- Safety: Yakakwana preloading nguva yakakosha kune kuchengetedzwa kwevashandisi. Iyo inoderedza njodzi yema electrode anonamatira kune workpieces, izvo zvinogona kuguma nenjodzi mamiriro kana uchiedza kuvaparadzanisa.
Kugadziridza Preloading Nguva
Kuti uwane yakanyanya kunaka weld mhando, zvakakosha kuti uone nguva yakafanira yekurodha yezvinhu chaizvo uye mamiriro ewelding. Zvinhu zvakadai semhando yezvinhu, ukobvu, uye inodiwa weld zvivakwa zvese zvinopesvedzera yakakodzera preloading nguva. Vagadziri vanowanzoita kuyedza kwakakura uye kuyedza kuti vamise maitiro akanakisa ezvishandiso zvavo.
Mukupedzisa, nepo preloading nguva ingaite senge diki diki mukupokana nzvimbo welding, ichokwadi, chinhu chakakosha chinogona kugadzira kana kutyora kunaka kweweld. Kuve nechokwadi chekuisa preloading nguva haingokonzerese kune akasimba, akavimbika welds asi zvakare inosimudzira kuchengetedzeka uye kugona mukuita welding. Chiyeuchidzo chekuti munyika yechokwadi welding, nguva yega yega yakakosha.
