I-Edm isetshenziselwa ikakhulukazi ukwenza izibunjwa zemishini nezingxenye ezinobunjwa obuyinkimbinkimbi bemigodi nemigodi; Ukucubungula izinto ezihlukahlukene zokuqhuba, njenge-alloy eqinile nensimbi eqinile; Ukucubungula izimbobo ezijulile nezinhle, izimbobo ezimise okukhethekile, ama-grooves ajulile, amalunga amancane nokusika izingcezu ezincane, njll; Ukucupha amathuluzi okwakha ahlukahlukene, izifanekiso namageji endandatho yochungechunge, njll.

Umgomo wokucubungula

Ngesikhathi se-EDM, i-electrode yamathuluzi kanye ne-workpiece ixhunywe ngokulandelana kwezigxobo ezimbili ze-pulse power supply bese icwiliswa oketshezini olusebenzayo, noma uketshezi olusebenzayo lukhokhiswa esikhaleni sokuphuma. igebe uhlelo oluzenzakalelayo lokulawula. Lapho igebe phakathi kwama-electrode amabili lifinyelela ebangeni elithile, i-voltage ye-impulse esetshenziswa kuma-electrode amabili izokwephula uketshezi olusebenzayo futhi ikhiphe inhlansi.

Esiteshini esincane sokukhishwa, inani elikhulu lamandla okushisa ligxilwa ngokushesha, izinga lokushisa lingaba phezulu njenge-10000 ℃ futhi ingcindezi ibuye ibe noshintsho olubukhali, ukuze ukulandelela izinto zensimbi zendawo endaweni yokusebenza yaleli phuzu ngokushesha. ncibilika futhi uhwamuke, bese uqhuma oketshezini olusebenzayo, ujiye ngokushesha, wakhe izinhlayiya zensimbi eqinile, futhi uthathwe uketshezi olusebenzayo. Ngalesi sikhathi phezu kwendawo yokusebenza kuzoshiya amamaki emigodi emincane, ukuphuma kuyema kafushane, uketshezi olusebenzayo phakathi kwama-electrode amabili ukuze kubuyiselwe isimo sokufakelwa.

I-voltage ye-pulse elandelayo ibe ihlehla kwenye indawo lapho ama-electrode esondelene khona, akhiqize ukuphuma kwenhlansi futhi aphinde inqubo.Ngakho, nakuba inani lensimbi eligqwalile ngokuphuma kwe-pulse lincane kakhulu, insimbi eyengeziwe ingaguguleka ngenxa. ezinkulungwaneni zokukhishwa kwe-pulse ngomzuzwana, ngokukhiqiza okuthile.

Ngaphansi kwesimo sokugcina igebe lokuphuma eliqhubekayo phakathi kwe-electrode yethuluzi kanye ne-workpiece, insimbi ye-workpiece iyagqwala kuyilapho i-electrode yethuluzi ifakwa ngokuqhubekayo endaweni yokusebenza, futhi ekugcineni umumo ohambisana nokuma kwe-electrode yethuluzi wenziwe ngomshini. Ngakho-ke, inqobo nje uma umumo we-electrode yamathuluzi kanye nemodi yokunyakaza ehlobene phakathi kwe-electrode yamathuluzi nomsebenzi, amaphrofayili ahlukahlukene ayinkimbinkimbi angenziwa ngomshini.Ama-electrode ethuluzi ngokuvamile enziwa ngezinto ezimelana nokugqwala ezine-conductivity enhle, indawo ephezulu yokuncibilika. kanye nokucubungula okulula, njengethusi, i-graphite, i-copper-tungsten alloy kanye ne-molybdenum.Enqubweni yomshini, i-electrode yethuluzi nayo inokulahlekelwa, kodwa ingaphansi kwenani lokugqwala kwensimbi yokusebenza, noma ngisho eduze nokulahlekelwa.

Njengendlela yokukhipha, uketshezi olusebenzayo luphinde lubambe iqhaza ekupholiseni nasekususweni kwe-chip ngesikhathi sokucutshungulwa.Amanzi ajwayelekile asebenzayo aphakathi nendawo ane-viscosity ephansi, i-flash point kanye nokusebenza okuzinzile, okufana nophalafini, amanzi ahlanziwe kanye ne-emulsion.Umshini we-spark kagesi uhlobo lokukhishwa okuzithokozisayo, izici zalo zimi kanje: ama-electrode amabili okukhishwa kwenhlansi ane-voltage ephezulu ngaphambi kokukhishwa, lapho ama-electrode amabili esondela, i-medium iphukile, bese kuvela ukukhishwa kwenhlansi. Kanye nenqubo yokuphuka, ukumelana phakathi kwama-electrode amabili kuncipha kakhulu, futhi i-voltage phakathi kwama-electrode nayo iyancipha kakhulu.Isiteshi senhlansi kufanele sicishwe ngesikhathi ngemva kokugcinwa isikhathi esifushane (imvamisa i-10-7-10-3s) ukuze kugcinwe “ i-cold pole” izici zokukhishwa kwenhlansi (okungukuthi, amandla okushisa okuguqulwa kwamandla esiteshi awafinyeleli ekujuleni kwe-electrode ngesikhathi), ukuze amandla esiteshi asetshenziswe ebangeni elincane.Umphumela wamandla wesiteshi ungabangela i-electrode okufanele igqwele endaweni.Indlela ekhiqizwa isenzakalo sokugqwala lapho kusetshenziswa ukukhishwa kwenhlansi yenza umshini wokulinganisa ubukhulu entweni ibizwa ngokuthi i-electric spark machining.I-Edm iwukukhishwa kwenhlansi endaweni ewuketshezi ngaphakathi kwebanga lamandla kagesi aphansi.Ngokwefomu ye-electrode yethuluzi kanye nezici zokunyakaza okuhlobene phakathi kwe-electrode yethuluzi kanye ne-workpiece, i-edM ingahlukaniswa ngezinhlobo ezinhlanu.Ukusikwa kwe-edM yocingo lwe-conductive materials kusetshenziswa i-axially moving wire njenge-electrode yethuluzi kanye ne-workpiece ehamba ngendlela oyifunayo nosayizi; kusetshenziswa ucingo noma ukwakha isondo lokugaya njengethuluzi le-electrode yembobo kakhiye noma ukwenza ukugaya;Isetshenziselwa ukwenza igeji yeringi yentambo, igeji yepulaki yentambo [1], igiya njll.Ukucutshungulwa kwezimbobo ezincane, i-alloying ebusweni, ukuqinisa ingaphezulu nezinye izinhlobo zokucubungula.I-Edm can izinto zokwakha kanye nokubunjwa okuyinkimbinkimbi okunzima ukusikwa ngezindlela ezijwayelekile zokusika.Awekho amandla okusika ngesikhathi somshini;Ayikhiqizi i-burr ne-cutting groove nezinye iziphambeko;Impahla ye-electrode yethuluzi akudingeki ibe nzima kune-workpiece material; Ukusetshenziswa okuqondile kukagesi ukucutshungulwa kwamandla, kulula ukufeza i-automation;Ngemva kokucubungula, indawo engaphezulu ikhiqiza ungqimba lwe-metamorphosis, okumele kwezinye izinhlelo zokusebenza luphinde lususwe;Kunzima ukubhekana nokungcoliswa kwentuthu okubangelwa ukuhlanzwa nokucubungula uketshezi olusebenzayo.
