I-Edm isetyenziselwa ubukhulu becala ukwenza izinto zokubumba kunye namacandelo aneemilo ezinzima zemingxunya kunye nemingxunya; Ukuqhubekeka kwezinto ezahlukeneyo zokuqhuba, ezinje nge-alloy elukhuni kunye nentsimbi eqinisiweyo; Iqhubekeka imingxunya enzulu kwaye intle, imingxunya ekhethekileyo-emile, iigrooves ezinzulu, amalunga amxinwa kunye nokusika izilayi ezincinci, njl .; Machining izixhobo ezahlukeneyo bokwakha, itemplates kunye nomtya ring gauge, njl

Inkqubo yokuqhubekeka

Ngexesha le-EDM, isixhobo esiyi-electrode kunye nendawo yokusebenza ziqhagamshelwe ngokulandelelana kwiipali ezimbini zamandla ombane kunye nokuntywiliselwa kulwelo olusebenzayo, okanye ulwelo olusebenzayo luhlawuliswa kwisikhewu sokukhutshwa. Inkqubo yolawulo oluzenzekelayo. Xa umsantsa ophakathi kwee-electrode ezimbini ufikelela kumgama othile, amandla ombane asetyenzisiweyo kwii-electrode ezimbini ayakwaphula ulwelo olusebenzayo kwaye avelise ukubhobhoza kwintlantsi.

Kwijelo elincinci lokukhupha, isixa esikhulu samandla obushushu sigxile kwangoko, iqondo lobushushu linokuphakama njenge-10000 ℃ kwaye uxinzelelo lukhona notshintsho olubukhali, ukuze izinto zentsimbi zilandele umkhondo kwindawo yokusebenza kwale ndawo kwangoko inyibilike kwaye iphefumle, kwaye iqhume kulwelo olusebenzayo, lukhawuleze ludibane, lwenze amasuntswana aqinileyo esinyithi, kwaye athathwe lulwelo olusebenzayo.Ngeli xesha kumphezulu womsebenzi uza kushiya imingxunya emincinci, ukukhutshwa kuyeke kancinci, Ukusebenza kolwelo phakathi kwee-electrode ezimbini ukubuyisela imeko yokugquma.

Umbane olandelayo ubetha emva kwenye indawo apho ii-electrode zisondele kakhulu, zivelisa ukukhutshwa kwentlantsi kwaye ziphinda inkqubo.Ngoko ke, nangona isixa sesinyithi esonakalisiweyo ngokukhupha ukubetha sincinci, intsimbi eninzi inokukhukuliseka ngenxa ukuya kumawaka okuphuma kokubetha ngomzuzwana, kunye nemveliso ethile.

Ngaphantsi kwemeko yokugcina umsantsa wokukhutshwa rhoqo phakathi kwesixhobo se-elektrode kunye nendawo yokusebenza, isinyithi se-workpiece sonakalisiwe ngelixa isixhobo se-electrode sondliwa ngokuqhubekayo kwindawo yokusebenza, kwaye ekugqibeleni imilo ehambelana nobume besixhobo i-electrode yenziwe ngomatshini. Ke ngoko, okoko nje ubume besixhobo se-electrode kunye nemowudi yokuhamba enxulumene phakathi kwesixhobo se-elektrode kunye nendawo yokusebenza, uninzi lweeprofayili ezintsonkothileyo zingenziwa ngomatshini.Ii-electrode zetekisi zihlala zenziwe ngezinto ezinokumelana nokubola kunye nokuqhuba kakuhle, indawo yokunyibilika ephezulu Ukuqhubekeka ngokulula, okunje ngobhedu, i-graphite, i-alloy-tungsten alloy kunye ne-molybdenum.Kwinkqubo yokuchwetheza, isixhobo i-electrode ikwanayo nelahleko, kodwa ingaphantsi kwesixa sokubola kwe-workpiece yesinyithi, okanye kufutshane nelahleko.

Njengomatshini wokukhupha, ulwelo olusebenzayo ludlala indima ekupholiseni nasekususeni i-chip ngexesha lokulungiswa.Amanzi asebenzayo aqhelekileyo aphakathi kunye ne-viscosity ephantsi, indawo ephezulu yokukhanya kunye nokusebenza okuzinzileyo, njengeparafini, amanzi amnyama kunye ne-emulsion. uhlobo lokukhutshwa ngokuzonwabisa, iimpawu zalo zezi zilandelayo: ii-electrode ezimbini zokukhutshwa kwintlantsi zinamandla ombane aphezulu ngaphambi kokuba zikhutshwe, xa iindlela ezimbini ze-electrode, eliphakathi lonakele, emva koko inkqubo yokuqhekeka yenzekile. ukumelana phakathi kwee-electrode ezimbini kuyehla kakhulu, kwaye umbane phakathi kwee-electrode nawo wehla ngokuqatha. Ijelo le-spark kufuneka licinywe ngexesha emva kokugcinwa ixesha elifutshane (ngesiqhelo i-10-7-10-3s) ukugcina " isibanda esibandayo ”Iimpawu zokukhutshwa kwentlantsi (okt, amandla obushushu etshaneli yamandla okuguqula ayifikeleli kubunzulu be-electrode ngexesha), ukuze amandla esitishi asetyenziswe Amandla amatsha wesitrato angabangela ukuba i-electrode idliwe kwindawo leyo. Indlela yokwenza i-corrosion evelisayo xa usebenzisa i-spark discharge yenza i-machining dimensional kwizinto ezibizwa ngokuba yi-electronics machining.Edm is a spark discharge in a liquid Ngokwendlela yesixhobo se-electrode kunye neempawu zentshukumo yokuhamba phakathi kwesixhobo se-electrode kunye ne-workpiece, i-edM inokwahlulahlulwa ibe ziindidi ezintlanu.Ukusika i-edM yokusika izixhobo eziqhubayo kusetyenziswa i-axially moving wire as tool electrode and Isixhobo sokusebenza esihamba kwimilo kunye nobukhulu obufunwayo; i-Edm yokugaya isebenzisa ucingo okanye ukwenza ivili lokugaya njengokuhambisa isixhobo sombhobho wesitshixo okanye ukwenza umngxunya; Isetyenziselwa ukwenza umtya weringi, umsonto weplagi [1], izixhobo njl. , ukomeleza umphezulu kunye nezinye iintlobo ze-processing.Edm inokuqhubekeka izinto kunye neemilo ezinzima ekunzima ukuzisika ngomatshini oqhelekileyo Akukho mandla okusika ngexesha lokuchwetheza; Ayivelisi i-burr kunye ne-groove yokusika kunye nezinye iziphene; Isixhobo se-electrode ayifuni kuba nzima kunezixhobo zokusebenza; Ukusetyenziswa ngokuthe ngqo kwamandla ombane, kulula ukufezekisa; Emva kokuqhubekeka, umphezulu uvelisa umaleko we-metamorphosis, apho kwezinye izicelo kufuneka ususwe; Kuyasokolisa ukujongana nongcoliseko lomsi olubangelwa kukuhlanjululwa nokulungiswa kolwelo olusebenzayo.
