Edm inonyanya kushandiswa kugadzira mold uye zvikamu zvine maumbirwo akaoma emakomba nemakomba; Kugadzira zvakasiyana-siyana conductive zvinhu, senge hard alloy nesimbi yakaoma; Kugadzira maburi akadzika uye akanaka, maburi akasarudzika, magonhi akadzika, majoini akamanikana uye kucheka zvimedu zvitete, nezvimwewo; Machina akasiyana ekugadzira maturusi, matemplate uye shinda mhete gauges, nezvimwe.

The processing principle

Munguva yeEDM, iyo electrode yekushandisa uye workpiece yakabatana nematanda maviri emagetsi ekufambisa uye kunyudzwa mumvura inoshanda, kana kuti mvura inoshanda inoiswa mugeji rekubuda.Iyo electrode yekushandisa inodzorwa kudyisa workpiece kuburikidza ne gap otomatiki control system. Kana gwanza riri pakati pemaelectrode maviri rasvika kune imwe chinhambwe, simba remhepo rinoshandiswa pamaelectrode maviri rinopwanya mvura inoshanda uye kuburitsa spark discharge.

Muiyo diki chiteshi chekuburitsa, huwandu hukuru hwesimba hwekupisa hunoiswa ipapo, tembiricha inogona kunge yakakwira kusvika 10000 ℃ uye kudzvanywa kunewo shanduko yakapinza, kuitira kuti yemuno inoteedzera simbi zvinhu panzvimbo yekushanda yeiyi poindi nekukasira. kunyunguduka uye kunyunguduka, uye kuputika mukati memvura inoshanda, nekukurumidza kunyunguduka, kuumba simbi yakasimba, uye inotorwa nemvura inoshanda. Panguva ino pamusoro peiyo workpiece ichasiya diki gomba mamaki, kubuda kwakamira kwenguva pfupi, iyo kushanda mvura pakati pema electrode maviri kudzorera iyo insulation state.

Inotevera pulse voltage inobva yaputsika pane imwe nzvimbo apo ma electrode anenge ari pedyo kune mumwe nemumwe, achibudisa spark discharge uye kudzokorora maitiro.Saka, kunyange zvazvo uwandu hwesimbi yakasvibiswa pamhepo inoyerera iduku zvikuru, simbi yakawanda inogona kuderedzwa nekuda. kusvika kuzviuru zvekubuda kwetsinga pasekondi imwe neimwe, paine kumwe kubereka.

Pasi pemamiriro ekuchengetedza gaka rinoramba riripo pakati pechishandiso electrode uye workpiece, simbi yeworkpiece yakasvibiswa apo electrode yekushandisa inoramba ichidyiswa muworkpiece, uye pakupedzisira chimiro chinoenderana nechimiro chechishandiso che electrode chinogadzirwa. Nokudaro, chero bedzi chimiro chechishandiso che electrode uye hukama hwekufamba mode pakati pechigadziro che electrode uye workpiece, zvakasiyana-siyana zvemashoko akaoma zvinogona kugadzirwa. uye nyore kugadzirisa, zvakadai semhangura, graphite, mhangura-tungsten alloy uye molybdenum.Muchigadziro chekugadzira, electrode yekushandisa inewo kurasikirwa, asi zvishoma kudarika kuwanda kwekuora kwesimbi workpiece, kana kunyange pedyo nekusarasikirwa.

Semvura inoyerera, iyo inoshandiswa inoshandiswa inoshandiswawo pakutonhora uye kubvisa chip panguva yekugadzirisa.Mafuta emvura anowanzoshanda ari pakati neine viscosity yakaderera, high flash point uye kushanda kwakagadzikana, zvakadai separafini, mvura yakasvibiswa uye emulsion.Electric spark machine is rudzi rwekuzvidadisa kubuda, maitiro ayo ndeaya anotevera: maelectrode maviri ekubuda kwe spark ane yakakwira voltage isati yabuda, kana maelectrode maviri asvika, iyo yepakati yakaputsika, ipapo kubuda kwe spark kunoitika. kupikisa pakati pema electrode maviri kunoderera zvakanyanya, uye magetsi ari pakati pemagetsi anodererawo zvakanyanya. The spark channel inofanira kudzimwa nenguva mushure mekuchengetedzwa kwenguva pfupi (kazhinji 10-7-10-3s) kuchengetedza " cold pole” maitiro ekubuda kwe spark (kureva kuti, simba rekupisa kwechannel simba rekushandura harisviki pakadzika kwe electrode nenguva), kuitira kuti simba remugero rishandiswe kune shoma shoma. electrode kuti ive ngura munharaunda.Nzira iyo iyo corrosion phenomenon inoburitsa kana ichishandisa spark discharge inoita dimensional machining kune zvinhu inonzi electric spark machining.Edm is a spark discharge in a liquid medium within a lower voltage range.Maererano nechimiro ye electrode yekushandisa uye hunhu hwekufamba pakati pechishandiso electrode uye workpiece, edM inogona kukamurwa kuita mhando shanu.Waya-yakacheka edM kucheka kwezvinhu conductive uchishandisa axially inofamba waya sechishandiso electrode uye workpiece ichifamba pamwe nechimiro chaunoda uye saizi;Edm kugaya kushandisa waya kana kugadzira conductive grinding vhiri sechokushandisa electrode ye keyhole kana kugadzira kugaya;Inoshandiswa kugadzira thread ring gage, thread plug gage [1], giya etc.Small buri processing, surface alloying, surface kusimbisa uye mamwe marudzi ekugadzirisa.Edm can process zvinhu uye maumbirwo akaomarara kutemwa neakajairwa machining nzira.Hapana simba rekucheka panguva yekugadzira;Haiburitse burr uye yekucheka groove nezvimwe zvinokanganisa;Chishandiso che electrode zvinhu hazvifanirwe kuoma kupfuura iyo workpiece zvinhu;Kushandisa kwakananga kwemagetsi. kugadzirwa kwemagetsi, kuri nyore kuwana otomatiki; Mushure mekugadzirisa, iyo nzvimbo inoburitsa metamorphosis layer, iyo mune mamwe maapplication inofanirwa kubviswazve; Zvinonetsa kubata nekusvibiswa kwehutsi kunokonzerwa nekucheneswa uye kugadzirisa kwemvura inoshanda.
