I-Edm isetyenziswa ikakhulu kumatshini wokubumba kunye neenxalenye ezinemilo entsonkothileyo yemingxuma kunye nemingxuma; Ukucubungula izinto ezahlukeneyo zokuqhuba, ezifana ne-alloy eqinile kunye nentsimbi eqinile; Ukucubungula imingxuma enzulu kunye nelungileyo, imingxuma ekhethekileyo, i-grooves enzulu, amajoyina amancinci kunye nokusika amacwecwe amancinci, njl.; Ukutshiza izixhobo ezahlukeneyo zokubumba, iitemplates kunye neegeji zeeringi zentambo, njl.

Umgaqo wokucubungula

Ngexesha le-EDM, i-electrode yesixhobo kunye ne-workpiece idityaniswe ngokulandelelana kwiipali ezimbini ze-pulse power supply kwaye igxininiswe kulwelo olusebenzayo, okanye ulwelo olusebenzayo luhlawuliswa kwi-gap yokukhupha.I-electrode yesixhobo ilawulwa ukondla i-workpiece ngokusebenzisa isikhewu inkqubo yolawulo oluzenzekelayo. Xa isithuba phakathi kwee-electrode ezimbini sifikelela kumgama othile, i-voltage ye-impulse esetyenziswe kwii-electrode ezimbini iya kuphula ulwelo olusebenzayo kwaye ivelise ukukhutshwa kwe-spark.

Kwijelo elincinci lokukhupha, inani elikhulu lamandla obushushu ligxininiswe ngokukhawuleza, iqondo lobushushu linokuba phezulu njenge-10000 ℃ kwaye uxinzelelo lunotshintsho olubukhali, ukwenzela ukuba ukulandelela izinto zetsimbi zendawo kwindawo yokusebenza kule ndawo ngokukhawuleza. nyibilika kwaye ube ngumphunga, kwaye ugqabhuke kulwelo olusebenzayo, ujiya ngokukhawuleza, wenze amasuntswana esinyithi aqinileyo, kwaye uthathwe lulwelo olusebenzayo.Ngeli xesha kumphezulu wesixhobo sokusebenza siya kushiya amanqaku emingxuma amancinci, ukukhutshwa kuyeka ngokufutshane, ulwelo olusebenzayo phakathi kwee-electrode ezimbini ukubuyisela imeko yokugquma.

I-voltage ye-pulse elandelayo ihlehla kwenye indawo apho i-electrodes isondelelene enye kwenye, ivelisa ukukhutshwa kwe-spark kunye nokuphindaphinda inkqubo. Ngaloo ndlela, nangona isixa sesinyithi esidliwe ngokukhutshwa kwe-pulse sincinci kakhulu, isinyithi esingaphezulu sinokuchithwa ngenxa. ukuya kumawaka okukhutshwa kwe-pulse ngomzuzwana, kunye nemveliso ethile.

Ngaphantsi kwemeko yokugcina i-gap yokukhupha rhoqo phakathi kwe-electrode yesixhobo kunye ne-workpiece, isinyithi se-workpiece sigqwala ngelixa i-electrode yesixhobo isoloko isondliwa kwi-workpiece, kwaye ekugqibeleni imilo ehambelana nokumila kwesixhobo se-electrode senziwa ngomatshini. Ngoko ke, ukuba nje imilo yesixhobo se-electrode kunye nemowudi yentshukumo ehambelanayo phakathi kwe-electrode yesixhobo kunye ne-workpiece, iindidi zeeprofayili eziyinkimbinkimbi zingenziwa ngomatshini.Ii-electrode zesixhobo zihlala zenziwe Izinto ezikwaziyo ukumelana nokugqwala kunye ne-conductivity elungileyo, indawo ephezulu yokunyibilika kunye nokusetyenzwa lula, njengobhedu, igraphite, i-copper-tungsten alloy kunye ne-molybdenum. workpiece metal, okanye kufutshane ukuba akukho ilahleko.

Njengomthombo wokukhupha, i-fluid esebenzayo nayo idlala indima ekupholiseni kunye nokususwa kwe-chip ngexesha lokucubungula.Amanzi asebenzayo aqhelekileyo aphakathi kunye ne-viscosity ephantsi, i-flash point kunye nokusebenza okuzinzileyo, njenge-kerosene, amanzi ahlanjululweyo kunye ne-emulsion.Umatshini we-spark wombane uhlobo oluzikhuphayo oluzikhuphayo, iimpawu zalo zimi ngolu hlobo lulandelayo: ii-electrodes ezimbini ze-spark discharge zine-voltage ephezulu ngaphambi kokuphuma, xa zombini I-electrodes isondela, i-medium iyaphulwa, emva koko ukukhutshwa kwe-spark kwenzeka.Kunye nenkqubo yokuphuka, ukuchasana phakathi kwee-electrode ezimbini kuncipha ngokukhawuleza, kwaye i-voltage phakathi kwee-electrodes nayo iyancipha ngokukhawuleza.I-spark channel kufuneka icinywe ngexesha emva kokugcinwa. ixesha elifutshane (ngokuqhelekileyo i-10-7-10-3s) ukugcina iimpawu "zezibonda ezibandayo" zokukhutshwa kwe-spark (oko kukuthi, amandla okushisa omzila ukuguqulwa kwamandla akufikeleli kubunzulu be-electrode ngexesha), ukwenzela ukuba amandla omzila asetyenziswe kuluhlu oluncinci.Isiphumo samandla ombane sinokubangela ukuba i-electrode ihlanjululwe kwindawo.Indlela eyenziwa yi-corrosion phenomenon evelisayo xa usebenzisa. Ukukhutshwa kwentlantsi kukhupha i-dimensional machining kwinto ebizwa ngokuba yi-electric spark machining.I-Edm kukukhupha intlantsi kwindawo yolwelo ngaphakathi kombane osezantsi. Uluhlu.Ngokohlobo lwesixhobo se-electrode kunye neempawu zentshukumo ehambelanayo phakathi kwesixhobo se-electrode kunye ne-workpiece, i-edM inokwahlulwa ibe ziindidi ezintlanu. imilo kunye nobukhulu;I-Edm yokusila kusetyenziswa ucingo okanye ukwenza ivili lokusila eliqhubayo njengesixhobo se-electrode yomngxuma wesitshixo okanye ukugaya;Isetyenziselwa ukwenza i-machining thread ring gage, intambo iplagi gage [1], igiya etc.Ukulungiswa komngxuma omncinci, ialloying surface, ukomeleza umphezulu kunye nolunye uhlobo lweprosesa.I-Edm inokusebenza imathiriyeli kunye neemilo ezintsonkothileyo ekunzima ukunqunyulwa ngeendlela eziqhelekileyo zomatshini.Akukho mandla okusika ngexesha lomatshini;Ayenzi ukuvelisa i-burr kunye ne-groove yokusika kunye nezinye iziphene;Isixhobo se-electrode imathiriyeli akufuneki ibe nzima kunesixhobo sokusebenza; Ukusetyenziswa ngokuthe ngqo kokusetyenzwa kwamandla ombane, kulula ukufikelela kwi-automation; Emva kokucubungula, umphezulu uvelisa umaleko we-metamorphosis, othi kwezinye izicelo kufuneka zisuswe ngakumbi;Kuyingxaki ukujongana nongcoliseko lomsi olubangelwa kukucocwa kunye nokulungiswa kolwelo olusebenzayo.
