Edm inonyanya kushandiswa pakugadzira maforoma nezvikamu zvine maumbirwo akaomarara emakomba nemakomba; Kugadzira zvinhu zvakasiyana-siyana zvinofambisa mhepo, zvakaita sesimbi yakaoma nesimbi yakaoma; Kugadzira makomba akadzika neakanaka, makomba ane chimiro chakasarudzika, migero yakadzika, majoini akatetepa uye kucheka zvidimbu zvitete, nezvimwewo; Kugadzira maturusi akasiyana-siyana ekuumba, matemplate uye tambo dzeringi, nezvimwewo.

Nheyo yekugadzirisa

Munguva yeEDM, electrode yechishandiso nechishandiso chebasa zvakabatana nematanda maviri esimba repulse uye zvinonyudzwa mumvura inoshanda, kana kuti mvura inoshanda inochajwa mugomba rekubuditsa. Electrode yechishandiso inodzorwa kuti ipe workpiece kuburikidza negwara rekutonga otomatiki. Kana mukana uri pakati pema electrode maviri wasvika padaro rakati, simba remagetsi rinoshandiswa pama electrode maviri richapwanya mvura inoshanda uye rinoburitsa spark discharge.

Muchikamu chidiki chekubuda kwemhepo, simba guru rekupisa rinoiswa ipapo ipapo, tembiricha inogona kusvika 10000℃ uye kumanikidzwa kwacho kunochinjawo zvakanyanya, zvekuti zvinhu zvesimbi zviri panzvimbo iyi zvinonyunguduka nekupwanyika, zvoputika mumvura inoshanda, zvinokurumidza kuungana, zvoumba zvidimbu zvesimbi yakasimba, uye zvinotorwa nemvura inoshanda. Panguva ino pamusoro pechinhu chebasa chichasiya mavanga madiki egomba, kubuda kwemhepo kwakamira kwenguva pfupi, mvura inoshanda pakati pemaerekitironi maviri kuti idzorere mamiriro ekudzivirira.

Voltage inotevera yepulse inobva yaparara pane imwe nzvimbo apo maelectrode anenge ari pedyo, zvichiburitsa spark discharge uye zvichidzokorora maitiro acho. Saka, kunyangwe huwandu hwesimbi inoora papulse discharge iri hudiki kwazvo, simbi yakawanda inogona kupwanyika nekuda kwezviuru zvepulse discharges pasekondi, nekubudirira kwakati.

Kana paine mukana wekuti simbi yechinhu ichi irambe iripo pakati peelectrode yechishandiso nechishandiso, simbi yechinhu ichi inoora nepo electrode yechishandiso ichigara ichiiswa muchishandiso, uye pakupedzisira chimiro chinoenderana nechimiro cheelectrode yechishandiso chinogadzirwa. Saka, chero bedzi chimiro cheelectrode yechishandiso uye modhi yekufamba pakati peelectrode yechishandiso nechishandiso, ma profiles akasiyana-siyana akaomarara anogona kugadzirwa. Maelectrode echishandiso anowanzo gadzirwa nezvinhu zvinodzivirira ngura zvine conductivity yakanaka, nzvimbo yakakwira yekunyunguduka uye nyore kugadzira, zvakaita semhangura, graphite, copper-tungsten alloy uye molybdenum. Mukushanda kwekugadzira, electrode yechishandiso inorasikirwawo, asi iri pasi pehuwandu hwekuora kwesimbi yechishandiso, kana kutoti hapana kurasikirwa kwakawanda.

Senzira yekubuditsa mvura, mvura inoshanda inoitawo basa rekutonhodza uye kubvisa chips panguva yekugadzirisa. Mvura inoshanda kazhinji idiki ine viscosity yakaderera, flash point yakakwira uye mashandiro akagadzikana, akadai separafini, mvura yakabviswa ioni uye emulsion. Muchina wemagetsi we spark rudzi rwekubuditsa mvura unozvifadza, hunhu hwawo ndehwekuti: ma electrodes maviri e spark discharge ane voltage yakakwira asati abuditsa, kana ma electrodes maviri asvika, medium inoputsika, ipapo spark discharge inoitika. Pamwe chete nemaitiro ekuputsika, resistance pakati pema electrodes maviri inoderera zvakanyanya, uye voltage iri pakati pema electrodes inodererawo zvakanyanya. Spark channel inofanira kudzimwa nenguva mushure mekuchengetedzwa kwenguva pfupi (kazhinji 10-7-10-3s) kuchengetedza hunhu hwe "cold pole" ye spark discharge (kureva, simba rekupisa rekushandurwa kwesimba re channel harisviki pakadzika kwe electrode nenguva), kuitira kuti simba re channel rishandiswe kusvika padanho diki. Mhedzisiro yesimba re channel inogona kukonzera kuti electrode iparare munzvimbo. Nzira iyo corrosion inoburitsa pakushandisa spark discharge inoita dimensional machining kuti Chinhu ichi chinonzi machining yemagetsi. Edm itsvina inobuda mumvura ine simba iri pasi pevoltage. Zvichienderana nechimiro che electrode yemidziyo uye hunhu hwekufamba pakati pe electrode yemidziyo ne workpiece, edM inogona kukamurwa kuita mhando shanu. Kucheka edM nezvinhu zvinofambisa uchishandisa waya inofamba ne axially se tool electrode ne workpiece zvichifamba nechimiro nehukuru hwaunoda; kukuya kweEdm uchishandisa waya kana kugadzira vhiri rekukuya rinofambisa se tool electrode yekiyi kana kugadzira grinding; Inoshandiswa pakugadzira thread ring gage, thread plug gage [1], giya nezvimwewo. Kugadzira maburi madiki, alloying pamusoro, kusimbisa pamusoro uye mamwe marudzi ekugadzirisa. Edm inogona kugadzirisa zvinhu nemaumbirwo akaomarara akaoma kuchekwa nenzira dzemazuva ese dzekugadzira. Hapana simba rekucheka panguva yekugadzira; Haiburitse burr ne cutting groove nezvimwe zvikanganiso; Chinhu che electrode yemidziyo hachifanirwe kuoma kupfuura chinhu che workpiece; Kushandiswa zvakananga kwemagetsi ekugadzirisa, zviri nyore kuita otomatiki; Mushure mekugadzirisa, pamusoro payo panogadzira metamorphosis layer, iyo mune mamwe maapplication inofanira kubviswa zvakanyanya; Zvinonetsa kugadzirisa kusvibiswa kweutsi kunokonzerwa nekucheneswa nekugadzirwa kwebasa. mvura.
