EDMndi makina opangira makina omwe makamaka amagwiritsa ntchito electrode yotulutsa (EDM electrode) yokhala ndi geometry yeniyeni kuti awotche geometry ya electrode pa gawo lachitsulo (conductive).Ndondomeko ya EDMnthawi zambiri amagwiritsidwa ntchito popanga zinthu zopanda kanthu komanso zakufa.
Njira yopangira zida zamagetsi pogwiritsa ntchito chiwopsezo cha dzimbiri chopangidwa ndi spark discharge amatchedwa EDM.EDM ndi spark discharge mu sing'anga yamadzimadzi pamtunda wotsika kwambiri.
EDM ndi mtundu wodzisangalatsa wokha, ndipo makhalidwe ake ndi awa: Ma electrode awiri a spark discharge amakhala ndi magetsi apamwamba asanayambe kutulutsa.Pamene ma elekitirodi awiri ali pafupi wina ndi mzake, sing'anga pakati pawo itasweka, kutuluka kwa spark kumachitika nthawi yomweyo.Ndi njira yowonongeka, kukana pakati pa ma electrode awiriwa kumachepa kwambiri, ndipo voteji pakati pa ma electrode awiriwa amachepetsanso kwambiri.Njira ya spark iyenera kuzimitsidwa pakapita nthawi mutakhala ndi nthawi yochepa (nthawi zambiri 10-7-10-3s), kuti mukhalebe ndi mawonekedwe a "mzati wozizira" wa spark discharge (ndiko kuti, mphamvu ya kutentha ya kutembenuka kwa mphamvu ya njira. sangathe kufalitsidwa mpaka kuya kwa electrode), kotero kuti mphamvu ya Channel imagwira ntchito pang'ono kwambiri.Zotsatira za mphamvu zamakina zimatha kupangitsa kuti ma elekitirodi awonongeke pang'ono.
Mawonekedwe:
1.EDM ndi ya makina osalumikizana nawo
Palibe kulumikizana kwachindunji pakati pa electrode ya chida ndi chogwirira ntchito, koma pali kusiyana kotulutsa.Kusiyana kumeneku kumakhala pakati pa 0.05 ~ 0.3mm, ndipo nthawi zina kumatha kufika 0.5mm kapena kukulirapo.The kusiyana ndi wodzazidwa ndi madzimadzi ntchito, ndi kuthamanga Kuthamanga kumaliseche, kutulutsa dzimbiri pa workpiece.
2.Kodi "kugonjetsa kukhwima ndi kufewa"
Popeza EDM imagwiritsa ntchito mwachindunji mphamvu yamagetsi ndi mphamvu yotentha kuti ichotse zinthu zachitsulo, imakhala yochepa kwambiri ndi mphamvu ndi kuuma kwa zinthu zogwirira ntchito, kotero kuti ma electrode a chida chofewa angagwiritsidwe ntchito pokonza zida zogwira ntchito mwakhama kuti akwaniritse "kufewa kumagonjetsa kulimba".
3.Ikhoza kukonza zitsulo zilizonse zovuta ku makina ndi zipangizo zopangira
Popeza kuchotsa zinthu pa processing zimatheka ndi mphamvu ya magetsi ndi matenthedwe kumaliseche, machinability zipangizo makamaka zimadalira madutsidwe magetsi ndi matenthedwe katundu wa zinthu, monga kusungunuka mfundo, kuwira mfundo, enieni kutentha mphamvu, matenthedwe madutsidwe, resistivity. , etc., pamene pafupifupi Iwo alibe chochita ndi katundu wake makina (kuuma, mphamvu, etc.).Mwanjira imeneyi, imatha kupyola malire a zida zodulira zachikhalidwe pazida, ndipo imatha kuzindikira kukonza zida zolimba komanso zolimba zokhala ndi zida zofewa, komanso zida zolimba kwambiri monga mizere ya diamondi ya polycrystalline ndi nitride ya kiyubiki ya boroni imatha kukonzedwa.
4.Mawonekedwe owoneka bwino amatha kupangidwa
Popeza mawonekedwe a electrode chida akhoza kungotengera workpiece, makamaka oyenera processing wa workpieces ndi akalumikidzidwa pamwamba akalumikidzidwa, monga zovuta patsekeke nkhungu processing.Makamaka, kukhazikitsidwa kwaukadaulo wowongolera manambala kumapangitsa kuti zikhale zenizeni kugwiritsa ntchito maelekitirodi osavuta kukonza magawo okhala ndi mawonekedwe ovuta.
5.Parts ndi zofunikira zapadera zimatha kukonzedwa
Ikhoza kukonza magawo omwe ali ndi zofunikira zapadera monga mipanda yopyapyala, zotanuka, zosasunthika, mabowo ang'onoang'ono, mabowo apadera, mabowo akuya, ndi zina zotero, komanso amatha kupanga zilembo zazing'ono pa nkhungu.Popeza chida elekitirodi ndi workpiece si kukhudzana mwachindunji pa Machining, palibe kudula mphamvu Machining, choncho ndi oyenera Machining workpieces otsika-rigidity ndi micromachining.
EDM ndi mtundu umodzi wa makina opanga makina, titha kukuthandizani kuthana ndi vuto lanu.
Ngati muli ndi mafunso kapena mukufuna ntchito iliyonse yokhudzana ndi CNC Machining, chonde titumizireni momasuka.
