I-Edm isetyenziselwa kakhulu umatshini wokwenza izinto kunye neendawo ezineemilo ezintsonkothileyo zemingxuma kunye nemingxuma; Ukucubungula izinto ezahlukeneyo zokuqhuba, ezifana ne-alloy eqinileyo kunye nentsimbi eqinileyo; Ukucubungula imingxuma enzulu necolekileyo, imingxuma enemilo ekhethekileyo, imingxunya enzulu, amalungu amancinci kunye nokusika izilayi ezibhityileyo, njl.njl.; Ukucubungula izixhobo ezahlukeneyo zokwenza, iitemplate kunye neegeyiji zeringi yentambo, njl.njl.

Umgaqo wokucubungula

Ngexesha le-EDM, i-electrode yesixhobo kunye ne-workpiece ziqhagamshelwe kwiipali ezimbini zombane we-pulse kwaye zifakwe kulwelo olusebenzayo, okanye ulwelo olusebenzayo lutshajwa kwi-discharge gap. I-electrode yesixhobo ilawulwa ukondla i-workpiece ngenkqubo yolawulo oluzenzekelayo lwe-gap. Xa i-gap phakathi kwee-electrode ezimbini ifikelela kumgama othile, i-impulse voltage esetyenziswa kwii-electrode ezimbini iya kuqhekeza ulwelo olusebenzayo kwaye ivelise i-spark discharge.

Kwi-micro channel yokukhupha, amandla amaninzi obushushu axutywe ngoko nangoko, ubushushu bunokuba phezulu ukuya kwi-10000℃ kwaye uxinzelelo lunotshintsho olukhulu, ukuze izinto zesinyithi ezilandelelanayo zasekuhlaleni kumphezulu wokusebenza kweli nqaku zinyibilike kwaye zibe ngumphunga ngoko nangoko, kwaye ziqhume zibe lulwelo olusebenzayo, zijike ngokukhawuleza, zenze amasuntswana esinyithi aqinileyo, kwaye zithathwe lulwelo olusebenzayo. Ngeli xesha kumphezulu we-workpiece kuya kushiya amanqaku amancinci emigodini, ukukhupha kuyeke okwethutyana, ulwelo olusebenzayo phakathi kwee-electrodes ezimbini ukubuyisela imeko yokukhusela.

I-voltage elandelayo ye-pulse iyaphela kwenye indawo apho ii-electrode zisondelelene khona, zivelisa i-spark discharge kwaye iphinda le nkqubo. Ngoko ke, nangona ubungakanani besinyithi esigqwalileyo kwi-pulse discharge nganye buncinci kakhulu, isinyithi esingakumbi sinokutsha ngenxa yamawaka e-pulse discharges ngomzuzwana, kunye nemveliso ethile.

Phantsi kwemeko yokugcina umsantsa wokukhupha oqhubekayo phakathi kwe-electrode yesixhobo kunye ne-workpiece, isinyithi se-workpiece siyabola ngelixa i-electrode yesixhobo ifakwa rhoqo kwi-workpiece, kwaye ekugqibeleni imo ehambelana nemilo ye-electrode yesixhobo iyabola. Ke ngoko, logama nje imo ye-electrode yesixhobo kunye nemo yokuhamba phakathi kwe-electrode yesixhobo kunye ne-workpiece, iintlobo ngeentlobo zeeprofayili ezintsonkothileyo zinokubola. Ii-electrode zezixhobo zihlala zenziwe ngezinto ezimelana nokubola ezine-conductivity elungileyo, indawo yokunyibilika ephezulu kunye nokucutshungulwa okulula, ezifana ne-copper, i-graphite, i-copper-tungsten alloy kunye ne-molybdenum. Kwinkqubo yokugaya, i-electrode yesixhobo nayo inelahleko, kodwa ingaphantsi kobungakanani bokubola kwesinyithi se-workpiece, okanye iphantse ilahlekelwe.

Njengesixhobo sokukhupha umbane, ulwelo olusebenzayo lukwadlala indima ekupholiseni nasekususeni iitshiphusi ngexesha lokucubungula. Ulwelo oluqhelekileyo olusebenzayo luphakathi olune-viscosity ephantsi, i-flash point ephezulu kunye nokusebenza okuzinzileyo, njenge-kerosene, amanzi angena-ionized kunye ne-emulsion. Umatshini we-spark wombane luhlobo lokukhupha oluzivuselelayo, iimpawu zawo zezi zilandelayo: ii-electrode ezimbini zokukhupha umbane zine-voltage ephezulu ngaphambi kokukhupha, xa ii-electrode ezimbini zisondela, i-medium iyaqhekeka, emva koko kuvela ukukhupha umbane. Kunye nenkqubo yokuqhekeka, ukumelana phakathi kwee-electrode ezimbini kuncipha kakhulu, kwaye umbane phakathi kwee-electrode nawo uyancipha kakhulu. Itshaneli ye-spark kufuneka icinywe ngexesha emva kokugcinwa ixesha elifutshane (ngesiqhelo i-10-7-10-3s) ukugcina iimpawu "ze-cold pole" zokukhupha umbane (oko kukuthi, amandla obushushu okuguqulwa kwamandla etshaneli awafikeleli kubunzulu be-electrode ngexesha), ukuze amandla etshaneli asetyenziswe kuluhlu oluncinci. Isiphumo samandla etshaneli sinokubangela ukuba i-electrode ibole kwindawo. Indlela apho isiganeko sokukhupha umbane esiveliswa xa kusetyenziswa ukukhupha umbane senza i-dimensional machining ukuze Le nto ibizwa ngokuba yi-electric spark machining. I-Edm yi-spark discharge kwi-liquid medium ngaphakathi koluhlu oluphantsi lwe-voltage. Ngokwemo ye-tool electrode kunye neempawu zokuhamba phakathi kwe-tool electrode kunye ne-workpiece, i-edM inokwahlulwa ibe ziintlobo ezintlanu. Ukusikwa kwe-edM ngentambo kusetyenziswa i-wire moving wire njenge-tool electrode kunye ne-workpiece ehamba ngokwemilo nobukhulu obufunekayo; Ukusikwa kwe-Edm kusetyenziswa i-wire okanye ukwenza i-conductive grinding wheel njenge-tool electrode ye-keyhole okanye yokwenza i-grinding; Isetyenziselwa ukwenza i-thread ring gage, i-thread plug gage [1], i-gear njl. Ukucubungula imingxunya emincinci, ukuxuba umphezulu, ukuqinisa umphezulu kunye nezinye iintlobo zokucubungula. I-Edm inokucubungula izixhobo kunye neemilo ezintsonkothileyo ezinzima ukunqunyulwa ngeendlela eziqhelekileyo zokucoca. Akukho mandla okusika ngexesha lokucoca; Ayivelisi i-burr kunye ne-cutting groove kunye nezinye iziphene; Izinto ze-tool electrode akufuneki zibe nzima kunezinto ze-workpiece; Ukusetyenziswa ngokuthe ngqo kokucubungula amandla ombane, kulula ukuzifumana ngokuzenzekelayo; Emva kokucubungula, umphezulu uvelisa umaleko we-metamorphosis, ekufuneka kwezinye izicelo ususwe ngakumbi; Kunzima ukujongana nongcoliseko lomsi olubangelwa kukucocwa kunye nokusebenza komsebenzi. ulwelo.
