Ubwino wa graphite electrode

Ubwino wa graphite electrode

(1) Ndi kuchulukirachulukira kwa die geometry ndi kusiyanasiyana kwa kagwiritsidwe ntchito ka zinthu, kulondola kwa makina a spark kumafunika kukhala kokwezeka.Electrode ya graphiteali ndi ubwino wa makina osavuta, kuchotsera kwakukulu kwa EDM ndi kuchepa kwa graphite. Chifukwa chake, makasitomala ena pamakina opangira spark amasiya ma elekitirodi amkuwa ndikugwiritsa ntchitoelectrode ya graphitem'malo mwake. Kuphatikiza apo, maelekitirodi ena apadera owoneka bwino sangathe kupangidwa ndi mkuwa, koma ma graphite ndi osavuta kupanga, ndipo elekitirodi yamkuwa ndi yolemera, yomwe siyiyenera kupangira ma elekitirodi akulu. Zinthu izi zimapangitsa makasitomala ena opanga makina a spark kuti agwiritse ntchito graphite electrode.

(2)Electrode ya graphiten'zosavuta pokonza, ndi processing liwiro mwachionekere mofulumira kuposa electrode mkuwa. Mwachitsanzo, liwiro processing wa graphite ndi ndondomeko mphero ndi 2-3 nthawi mofulumira kuposa zitsulo zina, ndipo palibe processing buku zina chofunika, pamene elekitirodi mkuwa amafuna Buku akupera. Mofananamo, ngati mkulu-liwiromakina a graphitepakati amagwiritsidwa ntchito kupanga elekitirodi, liwiro adzakhala mofulumira, dzuwa adzakhala apamwamba, ndipo vuto fumbi si kwaiye. Munjira izi, chida kuvala ndi kuwonongeka kwa elekitirodi yamkuwa kumatha kuchepetsedwa posankha zida zoyenera zolimba ndi graphite. Ngati nthawi ya mphero yaelectrode ya graphitePoyerekeza ndi electrode yamkuwa, ma elekitirodi a graphite amathamanga 67% kuposa a electrode yamkuwa. Nthawi zambiri, liwiro la makina a graphite elekitirodi ndi 58% mwachangu kuposa la elekitirodi yamkuwa. Mwanjira imeneyi, nthawi yokonza imachepetsedwa kwambiri, ndipo mtengo wopangira umachepetsedwa.

(3) Mapangidwe aelectrode ya graphitendizosiyana ndi electrode yamkuwa yachikhalidwe. Mafakitole ambiri a nkhungu nthawi zambiri amakhala ndi nkhokwe zosiyanasiyana pakupanga makina ovuta komanso omaliza a electrode yamkuwa, pomwe ma elekitirodi a graphite amagwiritsa ntchito nkhokwe zomwezo, zomwe zimachepetsa nthawi ya CAD / CAM ndi makina. Pachifukwa ichi chokha, ndikokwanira kuwongolera kulondola kwa nkhungu pamlingo waukulu.
