Mukugadzirwa chaiko kwewelding, mabhizinesi mazhinji anoona kuti kana michina yavo yewelding ichigadzira marara, mapoinzi eweld anongoramba ari pamusoro, achitadza kuumba anobudirira manyuchi. Izvi zvinokonzera kusakwana kwesimba rekubatana uye zvinokanganisa zvakanyanya kunaka kwechigadzirwa. Ichi chiitiko chinonyanya kuwanda mukugadzira mota uye maindasitiri emidziyo yemba.
Kuburikidza-nekuongorora kwakadzama, zvakaonekwa kuti chinokonzeresa chiri muhumwe humiro hwezinc layer-husina kunaka hwekupisa kwemafuta uye kushanduka kukuru-zvinoita kuti kupisa kusapinda mukati mepepa. Kunyatsogona kudzora kwepakati-nguva dzazvinomichina weldinginopa yakavimbika tekinoroji mhinduro kune iyi dambudziko.
Mu-Ongororo Yakadzama yeChinetso Chinokonzera Dambudziko
Traditionalmichina weldingkutarisana nematambudziko akawanda paunenge uchigadzira zvinhu zvesimbi:
- Iyo yakaipa yekupisa conductivity ye zinc layer inogadzira chivharo chekupisa, ichitadzisa kupisa kupisa kune base zvinhu.
- Tembiricha yekupisa ye zinc (inenge 907 degree) yakaderera pane tembiricha yekunyunguduka kwesimbi, zvichiita kuti nguva isati yakwana vaporization.
- Kuchinja-chinja kwazvino kunoguma nekusaenzana kwekupisa, nekupisa kwepamusoro uye kushaikwa kwemukati kwekusanganisa.
- Zinc vapor inosvibisa iyo electrode pamusoro, ichiwedzera kukanganisa kupisa kwekufambisa kushanda zvakanaka.
Zvakanakira Zvehunyanzvi zveMishini Yepakati-Frequency Spot Welding Machines
Yemazuvano yepakati-frequencymichina weldingkugadzirisa nyaya dzepamusoro welding kuburikidza neanotevera tekinoroji kubudirira:
- Shandura magetsi emagetsi kuita epakati-frequency DC simba pa800–2000 Hz.
- Wana kugadzikana kwepamusoro mukubuda kwazvino, kudzivirira kushanduka kwesimba kunowanzo mumidziyo yechinyakare.
- Kubuda kweDC kunobvisa maitiro eganda, zvichibvumira kupisa kusvika kune sheet bonding interface zvakananga.
- Millisecond-level precise control inoita kuti simba riburitswe panguva yakakwana.
Yakarongeka Solutions
1. Kugadziridzwa kweWelding Parameters
- Paunenge uchishandisa zvepakati-frequency spot welding machines, nzira dzinotevera dzeparameter dzinokurudzirwa:
- Wedzera zvakafanira nguva yepre-yekudzvanya (kuwedzera ne30–50%) kuti uone kudzingwa kwakakwana kwezinc layer.
- Gamuchira "yakaderera ikozvino + yakareba kutenderera" welding mode.
- Seta akawanda-zvirongwa zvekudziisa kuti uwedzere zvishoma nezvishoma simba rewelding.
- Shandisa zvakanaka{{0}tuning function yepakati-frequency spot welding machines kuti ugone kugonesa parameters.
2. Kudzora Kwazvo kweElectrode Pressure
- Wedzera kudzvanywa kwe electrode ne 20-30% kufambisa kudzingwa kweiyo yakanyungudutswa zinc layer.
- Chengetedza kugadzikana kwakagadzikana mukati mese welding process.
- Shandisa intelligent pressure control system yepakati-frequency spot welding machines.
- Iva nechokwadi chesimbi yakananga-ku-kusangana kwesimbi kuderedza kupisa kwemafuta.
3. Electrode Selection uye Design
- Sarudza maelectrode ane tapered kana spherical matipi ekuparadzira kupisa kwepasi.
- Recommended oxide-kupararira-yakasimbiswa copper electrode zvinhu zvepamusoro-kuramba tembiricha uye anti-adhesion properties.
- Electrode dhayamita inofanira kuva 5-6 nguva shizha ukobvu kuwedzera ano density.
- Gara uchipfeka maelectrodes kuti uchengetedze mamiriro ekushanda.
4. Surface Pretreatment Process
- Nyatsochenesa pamusoro pemafuta mavara uye oxides.
- Ita zvakanaka kukuya kwenzvimbo yewelding kana zvichidikanwa.
- Chengetedza kushata kwakakodzera kwepamusoro kusimudzira conduction yazvino.
- Dzivisa kukuya zvakanyanyisa zvinogona kukanganisa anti{0}}corrosion coating.
Implementation Results uye Quality Assurance
Mushure mekushandisa michina yepakati-yenguva yakawanda yewelding yakasanganiswa nemaitiro akakwenenzverwa:
- Welding qualification rate inowedzera kusvika pamusoro pe98%.
- Kudzika kweNugget kunosvika 70-80% yehupamhi hwemashizha.
- Simba rakabatana rinosangana nemhando yepamusoro-soro.
- Upenyu hwebasa reElectrode hunowedzera nepamusoro pe50%.
- Mari yekugadzira yakaderedzwa zvakanyanya.
Mhedziso
Iwo musimboti we galvanized sheet surface welding nyaya dziri mukusakwana chaiko mukudzora kupisa. Pakati-frequencymichina welding, neyakagadzikana yavo yazvino kubuda, chaiyo parameter kugadzirisa, uye nemashandisirwo esimba rekushandisa, inopa mhinduro yakakwana kune iyi indasitiri dambudziko.
Nekusarudza akakodzera epakati-yenguva yakawanda welding machine equipment nekuisanganisa nesainzi welding process parameters, makambani ekugadzira haangokwanisi kugadzirisa zvachose nyaya dzepamusoro welding asi zvakare kuvandudza zvakanyanya kunaka kwechigadzirwa uye kushanda zvakanaka kwekugadzirwa, kuwana mukana wehunyanzvi unoshamisa mumusika wemakwikwi.
