Ubwino wa ma electrode a graphite

Ubwino wa ma electrode a graphite

1: Kuchulukirachulukira kwa geometry ya nkhungu komanso kusiyanasiyana kwazinthu zomwe zimagwiritsidwa ntchito kwapangitsa kuti pakhale zofunikira zapamwamba komanso zapamwamba pakutulutsa kulondola kwa makina a spark. Ubwino wa maelekitirodi a graphite ndiwosavuta kukonza, kutulutsa kwakukulu kwa makina otulutsa magetsi, komanso kutayika kwa graphite. Chifukwa chake, makasitomala ena otengera makina a spark amasiya maelekitirodi amkuwa ndikusintha ma electrode a graphite. Kuphatikiza apo, maelekitirodi ena owoneka mwapadera sangapangidwe ndi mkuwa, koma ma graphite ndi osavuta kupanga, ndipo ma elekitirodi amkuwa ndi olemetsa komanso osayenerera kukonza maelekitirodi akulu. Zinthu izi zapangitsa makasitomala ena a makina a spark ogwiritsa ntchito ma electrode a graphite.

2: Maelekitirodi a graphite ndi osavuta kukonza, ndipo kuthamanga kwachangu kumathamanga kwambiri kuposa ma elekitirodi amkuwa. Mwachitsanzo, pogwiritsa ntchito luso la mphero pokonza graphite, liwiro lake lokonzekera ndi nthawi 2-3 mofulumira kuposa zitsulo zina ndipo sizifuna kusinthidwa kwamanja, pamene ma elekitirodi amkuwa amafunikira kugaya pamanja. Momwemonso, ngati malo opangira makina othamanga kwambiri a graphite agwiritsidwa ntchito popanga maelekitirodi, liwiro lidzakhala lofulumira komanso kuchita bwino kudzakhala kokulirapo, ndipo sipadzakhala vuto lafumbi. Munjira izi, kusankha zida zokhala ndi kuuma koyenera ndi graphite kungachepetse kuvala kwa zida ndi kuwonongeka kwa mkuwa. Ngati mufananiza nthawi yophera ma elekitirodi a graphite ndi ma elekitirodi amkuwa, ma elekitirodi a graphite ndi 67% mwachangu kuposa ma elekitirodi amkuwa. Nthawi zambiri magetsi otulutsa magetsi, ma electrode a graphite ndi 58% mwachangu kuposa maelekitirodi amkuwa. Mwanjira imeneyi, nthawi yokonza imachepetsedwa kwambiri, ndipo ndalama zopangira zimachepetsedwa.

3: Kapangidwe ka electrode ya graphite ndi yosiyana ndi yachikhalidwe yamkuwa yamagetsi. Mafakitole ambiri a nkhungu nthawi zambiri amakhala ndi malipiro osiyanasiyana opangira maelekitirodi amkuwa, pomwe ma elekitirodi a graphite amagwiritsa ntchito ndalama zofanana. Izi zimachepetsa kuchuluka kwa CAD/CAM ndi kukonza makina. Pachifukwa ichi chokha, Zokwanira kuwongolera kulondola kwa nkhungu pamlingo waukulu.

Zoonadi, fakitale ya nkhungu ikasintha kuchokera ku maelekitirodi amkuwa kupita ku maelekitirodi a graphite, chinthu choyamba chomwe chiyenera kumveka bwino ndi momwe mungagwiritsire ntchito zipangizo za graphite ndikuganiziranso zinthu zina. Masiku ano, makasitomala ena a makina opangira spark amagwiritsa ntchito ma graphite kutulutsa ma electrode discharge Machining, omwe amachotsa njira yopukutira nkhungu ndi kupukuta kwamankhwala, komabe amakwaniritsa zomwe zikuyembekezeka. Popanda kuwonjezera nthawi ndi kupukuta, ndizosatheka kuti electrode yamkuwa ipange chogwirira ntchito choterocho. Kuphatikiza apo, graphite imagawidwa m'makalasi osiyanasiyana. Kukonzekera koyenera kungathe kutheka pogwiritsa ntchito magawo oyenerera a graphite ndi magetsi a spark discharge parameters pansi pa ntchito zinazake. Ngati wogwiritsa ntchitoyo amagwiritsa ntchito magawo omwewo monga electrode yamkuwa pamakina a spark pogwiritsa ntchito ma electrode a graphite, ndiye kuti zotsatira zake ziyenera kukhala zokhumudwitsa. Ngati mukufuna mosamalitsa kulamulira zinthu elekitirodi, mukhoza anapereka graphite elekitirodi mu boma sanali imfa (kutaya zosakwana 1%) pa Machining akhakula, koma elekitirodi mkuwa si ntchito.

Graphite ili ndi izi zapamwamba kwambiri zomwe mkuwa sungafanane:

Processing liwiro: mkulu-liwiro mphero akhakula Machining ndi 3 nthawi mofulumira kuposa mkuwa; kutsirizitsa mphero yothamanga kwambiri ndi 5 nthawi mwachangu kuposa mkuwa

Makina abwino, amatha kuzindikira zojambula zovuta za geometric

Kulemera kopepuka, kachulukidwe kochepera 1/4 yamkuwa, ma elekitirodi ndi osavuta kuyimitsa

akhoza kuchepetsa chiwerengero cha maelekitirodi limodzi, chifukwa akhoza kumangidwa m'mitolo mu electrode ophatikizana

Kukhazikika kwamafuta abwino, osasinthika komanso ma burrs opangira
