Ubwino wa ma electrode a graphite

Ubwino wa ma electrode a graphite

1: Kuvuta kowonjezereka kwa mawonekedwe a nkhungu komanso kusiyanasiyana kwa ntchito za malonda kwapangitsa kuti pakhale zofunikira zambiri kuti makina otulutsa spark akhale olondola. Ubwino wa ma electrode a graphite ndi kukonzedwa kosavuta, kuchotsedwa kwakukulu kwa makina otulutsa magetsi, komanso kutayika kochepa kwa graphite. Chifukwa chake, makasitomala ena a makina otulutsa spark ochokera m'magulu amasiya ma electrode amkuwa ndikusintha kupita ku ma electrode a graphite. Kuphatikiza apo, ma electrode ena opangidwa mwapadera sangapangidwe ndi mkuwa, koma graphite ndi yosavuta kupanga, ndipo ma electrode amkuwa ndi olemera ndipo sayenera kukonzedwa ndi ma electrode akuluakulu. Zinthu izi zapangitsa kuti makasitomala ena a makina otulutsa spark ochokera m'magulu agwiritse ntchito ma electrode a graphite.

2: Ma electrode a grafiti ndi osavuta kuwakonza, ndipo liwiro lawo lokonza ndi lachangu kwambiri kuposa ma electrode amkuwa. Mwachitsanzo, pogwiritsa ntchito ukadaulo wopera pokonza graphite, liwiro lawo lokonza ndi lachangu ka 2-3 kuposa kukonza kwina kwachitsulo ndipo silifuna kukonza kwina kwamanja, pomwe ma electrode amkuwa amafunika kupukutidwa ndi manja. Mofananamo, ngati malo opangira ma graphite othamanga kwambiri agwiritsidwa ntchito popanga ma electrode, liwiro lawo lidzakhala lachangu ndipo magwiridwe antchito awo adzakhala apamwamba, ndipo sipadzakhala mavuto a fumbi. Mu njira izi, kusankha zida zolimba komanso graphite yoyenera kungachepetse kuwonongeka kwa zida ndi kuwonongeka kwa mkuwa. Ngati muyerekeza nthawi yopera ya ma electrode a graphite ndi ma electrode amkuwa, ma electrode a graphite ndi 67% mwachangu kuposa ma electrode amkuwa. Pa makina otulutsa magetsi ambiri, kukonza ma electrode a graphite ndi 58% mwachangu kuposa ma electrode amkuwa. Mwanjira imeneyi, nthawi yokonza imachepetsedwa kwambiri, ndipo ndalama zopangira zimachepetsedwanso.

3: Kapangidwe ka electrode ya graphite ndi kosiyana ndi ka electrode yamkuwa yachikhalidwe. Mafakitale ambiri a nkhungu nthawi zambiri amakhala ndi zovomerezeka zosiyanasiyana zokoka ndi kumaliza ma electrode amkuwa, pomwe ma electrode a graphite amagwiritsa ntchito zovomerezeka zofanana. Izi zimachepetsa kuchuluka kwa CAD/CAM ndi kukonza makina. Pachifukwa ichi chokha, Zokwanira kukonza kulondola kwa bowo la nkhungu kwambiri.

Zachidziwikire, fakitale ya nkhungu ikasintha kuchoka pa ma electrode amkuwa kupita ku ma electrode a graphite, chinthu choyamba chomwe chiyenera kukhala chomveka bwino ndi momwe mungagwiritsire ntchito zida za graphite ndikuganizira zina zokhudzana nazo. Masiku ano, makasitomala ena a makina opangidwa ndi gulu amagwiritsa ntchito graphite ku machining otulutsa ma electrode, zomwe zimachotsa njira yopukuta m'mimba mwa nkhungu ndi kupukuta mankhwala, koma zimakwaniritsabe mawonekedwe omwe amayembekezeredwa. Popanda kuwonjezera nthawi ndi njira yopukuta, sizingatheke kuti electrode yamkuwa ipange ntchito yotereyi. Kuphatikiza apo, graphite imagawidwa m'magawo osiyanasiyana. Zotsatira zabwino zokonzera zitha kupezeka pogwiritsa ntchito magiredi oyenera a graphite ndi magawo otulutsa ma spark amagetsi pansi pa ntchito zinazake. Ngati wogwiritsa ntchito agwiritsa ntchito ma parameter omwewo ndi electrode yamkuwa pamakina otulutsa ma spark pogwiritsa ntchito ma electrode a graphite, ndiye kuti zotsatira zake ziyenera kukhala zokhumudwitsa. Ngati mukufuna kuwongolera mosamala zinthu za electrode, mutha kuyika electrode ya graphite mu mkhalidwe wosatayika (kutayika kochepera 1%) panthawi yokonza molakwika, koma electrode yamkuwa sigwiritsidwa ntchito.

Graphite ili ndi makhalidwe abwino awa omwe mkuwa sungagwirizane nawo:

Liwiro lokonza: kupukuta kolimba kwambiri kumathamanga katatu kuposa mkuwa; kumaliza kupukuta kothamanga kwambiri kumathamanga kasanu kuposa mkuwa

Kugwira ntchito bwino, kumatha kuzindikira zovuta zojambulira zithunzi

Kulemera kopepuka, kachulukidwe ndi kochepera 1/4 ya mkuwa, ma electrode ndi osavuta kuwagwira

akhoza kuchepetsa chiwerengero cha ma electrode amodzi, chifukwa amatha kulumikizidwa mu electrode yophatikizana

Kukhazikika kwabwino kwa kutentha, palibe kusintha kwa masinthidwe komanso palibe ma burrs opangira
