Zvakanakira graphite electrodes
1: Kuwedzera kuomarara kwe mold geometry uye kusiyanisa kwemashandisirwo echigadzirwa kwakatungamira kune yakakwirira uye yepamusoro zvinodiwa pakuburitsa chokwadi chemushini we spark.Zvakanakira magraphite electrode zviri nyore kugadzirisa, kukwirira kubviswa kwemagetsi ekuburitsa machining, uye kuderera kwegraphite kurasikirwa.Naizvozvo, vamwe vatengi-based spark muchina vatengi vanosiya magetsi emhangura vochinjira kumagraphite electrodes.Mukuwedzera, mamwe ma electrode akakosha-akaumbwa haagone kugadzirwa nemhangura, asi graphite iri nyore kugadzira, uye electrode yemhangura inorema uye haina kukodzera kugadzirisa maelectrode makuru.Izvi zvinhu zvakakonzera vamwe vatengi-based spark muchina vatengi kushandisa graphite electrodes.
2: Graphite electrode iri nyore kugadzirisa, uye kumhanya kwekugadzirisa kunokurumidza kukurumidza kupfuura magetsi emhangura.Semuenzaniso, kushandisa tekinoroji yekugaya kugadzira graphite, iyo yekumhanyisa kumhanya inokurumidza 2-3 nguva kupfuura mamwe masimbi ekugadzira uye haidi mamwe manyorero ekugadzirisa, nepo mhangura electrode inoda manyore kugaya.Saizvozvowo, kana nzvimbo yepamusoro-soro ye graphite machining centre inoshandiswa kugadzira ma electrode, kukurumidza kuchave kwakakurumidza uye kubudirira kuchava kwakakwirira, uye hapazovi nematambudziko eguruva.Mune maitiro aya, kusarudza maturusi ane kuoma kwakakodzera uye graphite kunogona kuderedza kupfeka kwemidziyo uye kukuvara kwemhangura.Kana iwe uchinyatsoenzanisa nguva yekugaya ye graphite electrodes uye electrode yemhangura, magirafu emagetsi ari 67% nekukurumidza kupfuura magetsi emhangura.Mukuwanda kwemagetsi ekuburitsa machining, kugadzirwa kwemagraphite electrode kunokurumidza 58% kupfuura maelectrode emhangura.Nenzira iyi, nguva yekugadzirisa inoderedzwa zvakanyanya, uye mari yekugadzira inoderedzwawo.
3: Dhizaini ye graphite electrode yakasiyana neiyo yechinyakare mhangura electrode.Mafekitari mazhinji ekuumbwa anowanzo ane mibvumirano yakasiyana yekuomesera nekupedza maelectrode emhangura, nepo magirafu emagetsi anoshandisa anenge maallowances akafanana.Izvi zvinoderedza huwandu hweCAD/CAM uye kugadzirisa kwemuchina.Nokuda kwechikonzero ichi chete, Zvakakwana kuti uvandudze kururamisa kwegomba rekuumbwa kusvika pamwero mukuru.
Ehezve, mushure meiyo mold fekitori inochinja kubva kumhangura electrode kuenda ku graphite electrode, chinhu chekutanga chinofanira kujeka ndechekuti mashandisiro ekushandisa graphite zvinhu uye kufunga zvimwe zvinoenderana.Mazuva ano, vamwe vatengi veboka-based spark muchina vanoshandisa graphite kuita electrode discharge machining, iyo inobvisa maitiro ekuporiswa kwegomba nekuporiswa kwemakemikari, asi zvichiri kuzadzisa inotarisirwa kupera kwepamusoro.Pasina kuwedzera nguva uye kupenya, hazvibviri kuti electrode yemhangura ibudise workpiece yakadaro.Mukuwedzera, graphite yakakamurwa kuva mamakisi akasiyana.Iyo yakanaka yekugadzirisa mhedzisiro inogona kuwanikwa nekushandisa akakodzera mamakisi egraphite uye yemagetsi spark discharge paramita pasi pemashandisirwo chaiwo.Kana mushandisi akashandisa maparamendi akafanana seye electrode yemhangura pamushini we spark uchishandisa graphite electrodes, Ipapo mhedzisiro inofanirwa kuodza mwoyo.Kana iwe uchida kunyatso kudzora zvinhu zve electrode, unogona kuseta graphite electrode mune isina-kurasikirwa mamiriro (kurasikirwa isingasviki 1%) panguva yakaoma machining, asi electrode yemhangura haishandiswe.
Graphite ine anotevera emhando yepamusoro maitiro ayo mhangura haikwanise kuenderana:
Processing speed: high-speed milling rough machining inokurumidza 3 nguva kupfuura mhangura;high-speed milling finishing inokurumidza 5 nguva kupfuura mhangura
Yakanaka machinability, inogona kuona yakaoma geometric modelling
Huremu huremu, density ishoma pane 1/4 yemhangura, electrode iri nyore kusungirira
inogona kuderedza nhamba ye electrode imwe chete, nokuti inogona kusungirirwa mumagetsi akabatanidzwa
Kugadzikana kwakanaka kwekushisa, hapana deformation uye hapana kugadzirisa maburrs
