I-Edm isetshenziselwa ikakhulukazi ukwenza isikhunta semishini nezingxenye ezinezimo eziyinkimbinkimbi zemigodi nezimbobo Icubungula izinto ezahlukahlukene zokuqhuba, njenge-alloy enzima nensimbi eqinile; Icubungula izimbobo ezijulile nezicolekileyo, izimbobo ezimise okhethekile, ama-grooves ajulile, amalunga amancane kanye nokusika izingcezu ezincanyana, njll .; Machining amathuluzi ahlukahlukene ukwakha, izifanekiso kanye ngentambo indandatho Izikali, njll

Isimiso sokucubungula

Ngesikhathi se-EDM, i-electrode yethuluzi nomsebenzi wokusebenza kuxhunywe ngokulandelana ezigxotsheni ezimbili zamandla wokushaya ngamandla futhi kugxiliswa kuketshezi olusebenzayo, noma uketshezi olusebenzayo lufakwe esikhaleni sokukhipha. Ithuluzi le-electrode lilawulwa ukondla indawo yokusebenza igebe uhlelo lokulawula okuzenzakalelayo. Lapho igebe phakathi kwala ma-electrode amabili lifinyelela ibanga elithile, amandla we-impulse asetshenziswe kuma-electrode amabili azodiliza uketshezi olusebenzayo futhi akhiqize ukuphuma kwe-spark.

Esiteshini esincane sokukhipha, inani elikhulu lamandla okushisa ligxilwe khona manjalo, izinga lokushisa lingaba phezulu njenge-10000 ℃ futhi ingcindezi nayo inoshintsho olubukhali, ukuze izinto zensimbi zomkhondo zendawo zisebenze kuleli phuzu ngokushesha ncibilika futhi wenze umphunga, bese uqhuma ungene kuketshezi olusebenzayo, ujije ngokushesha, wakhe izinhlayiya zensimbi eziqinile, bese uthathwa yilolu ketshezi olusebenzayo.Ngalesi sikhathi ebusweni bendawo yokusebenza kuzoshiya amamaki amancane omgodi, ukukhipha kumile isikhashana, uketshezi olusebenzayo phakathi kwama-electrode amabili ukubuyisela isimo sokufakwa.

Amandla omoya alandelayo abe esehla kwesinye isikhathi lapho ama-electrode asondelene kakhulu, akhiqiza ukukhishwa kwenhlansi nokuphinda inqubo.Ngakho-ke, yize inani lensimbi elonakalisiwe ngokukhishwa kwe-pulse lincane kakhulu, insimbi eningi ingaguguleka ngenxa ezinkulungwaneni zamapayipi okukhishwa ngomzuzwana, ngomkhiqizo othile.

Ngaphansi kwesimo sokugcina igebe lokukhipha eliqhubekayo phakathi kwethuluzi le-electrode nomsebenzi wokusebenza, insimbi yomsebenzi isonakalisiwe ngenkathi i-electrode yethuluzi ifakwa ngokuqhubekayo ku-workpiece, ekugcineni umumo ohambelana nokuma kwethuluzi le-electrode lenziwe ngomshini. Ngakho-ke, inqobo nje uma ukwakheka kwe-electrode yethuluzi nemodi yokunyakaza ehlobene phakathi kwethuluzi le-electrode nendawo yokusebenza, amaphrofayili ahlukahlukene anzima angenziwa ngomshini.I-electrode yethuluzi imvamisa yenziwa ngezinto ezingamelana nokugqwala ezine-conductivity enhle, iphuzu lokuncibilika okuphezulu futhi ukucubungula okulula, okufana nethusi, i-graphite, ithusi-tungsten alloy kanye ne-molybdenum.Ku inqubo yokwenza imishini, i-electrode yethuluzi nayo ilahlekile, kepha ingaphansi kwenani lokugqwala kwensimbi yokusebenza, noma isondele ekulahlekelweni.

Njengomshini wokukhipha, uketshezi olusebenzayo lubamba iqhaza ekupholiseni nasekususeni i-chip ngesikhathi sokucubungula.Amanzi asebenzayo ajwayelekile aphakathi nendawo ane-viscosity ephansi, i-flash point ephezulu nokusebenza okuzinzile, njengophalafini, amanzi ahlanjululwe kanye ne-emulsion. uhlobo lokukhishwa okuzithokozisayo, izici zalo zimi kanje: ama-electrode amabili we-spark discharge ane-voltage ephezulu ngaphambi kokukhishwa, lapho ama-electrode amabili esondela, okuphakathi kudiliziwe, khona-ke ukukhishwa kwe-spark kwenzeka kanye nenqubo yokuwohloka, ukumelana phakathi kwama-electrode amabili kwehla kakhulu, futhi amandla aphakathi kwama-electrode nawo ancipha kakhulu.Isiteshi se-spark kufanele sicishwe ngesikhathi ngemuva kokugcinwa isikhathi esifushane (imvamisa kungu-10-7-10-3s) ukugcina " isibanda esibandayo ”izici zokukhishwa kwenhlansi (okungukuthi, amandla okushisa okuguqulwa kwamandla esiteshi angafiki ekujuleni kwe-electrode ngesikhathi), ukuze amandla esiteshi asetshenziselwe ububanzi obuncane.Umthelela wamandla wesiteshi ungadala ukuthi i-electrode idliwe endaweni.Indlela yokwenza into yokugqwala ekhiqiza lapho kusetshenziswa ukukhishwa kwe-spark kwenza imishini yokulinganisa entweni ebizwa ngokuthi yi-electric spark machining.Edm is a spark discharge in a liquid Ngokuya ngohlobo lwethuluzi le-electrode nezimpawu zokuhamba okuhambisanayo phakathi kwethuluzi i-electrode ne-workpiece, i-edM ingahlukaniswa ngezinhlobo ezinhlanu.Ukusika i-edM kwe-edM kwezinto ezisetshenziswayo kusetshenziswa ucingo oluhamba nge-axial njengethuluzi i-electrode futhi isiqeshana sokusebenza esihamba ngokuma nosayizi oyifunayo; I-Edm igaya isebenzisa ucingo noma yenza isondo lokugaya elenzayo njengethuluzi i-electrode ye-keyhole noma yokwakha ukugaya; Isetshenziselwa imishini yocingo lwendandatho, i-plug plug yegeji [1], igiya njll. , ukuqiniswa kwendawo nezinye izinhlobo zokucubungula.I-Edm ingacubungula izinto zokwakheka nokubunjwa okuyinkimbinkimbi okunzima ukusikwa ngemishini ejwayelekile izindlela.Akukho amandla okusika ngesikhathi semishini; Ayikhiqizi i-burr ne-cutting groove nezinye iziphambeko; Izinto zethuluzi le-electrode akudingeki zibe nzima kunezinto zokusebenza; Ukusetshenziswa okuqondile kokucutshungulwa kwamandla kagesi, kulula ukufeza okuzenzakalelayo; Ngemuva kokucubungula, indawo ikhiqiza ungqimba lwe-metamorphosis, okuthi kwezinye izinhlelo zokusebenza kufanele lususwe ngokuqhubekayo; Kuyinkinga ukubhekana nokungcola kwentuthu okubangelwa ukuhlanzwa nokucutshungulwa koketshezi olusebenzayo.
