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 ring gauges, nezvimwe.

The processing principle

Munguva yeEDM, iyo electrode yekushandisa uye workpiece yakabatanidzwa kune matanda maviri emagetsi ekuputika uye kunyudzwa mumvura inoshanda, kana kuti mvura inoshandiswa inotengeswa mugeji rekubuda.Iyo electrode yekushandisa inodzorwa kudyisa workpiece kuburikidza negap automatic 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 hunomisikidzwa pakarepo, tembiricha inogona kunge yakakwira kusvika 10000 ℃ uye kudzvanywa kunewo shanduko yakapinza, kuitira kuti simbi inoteedzera simbi iri panzvimbo yekushanda yeiyi poindi inonyunguduka nekupfava, uye inoputika mukati memvura inoshanda, nekukasira condense, inogadzira simbi yakasimba kubva panguva yekushanda, uye inotorwa kubva panguva yekushanda. madiki gomba mavanga, kubuda kwakamira kwenguva pfupi, mvura inoshanda pakati pema electrode maviri kudzoreredza mamiriro ekudzivirira.

Inotevera pulse voltage inobva yaputsika pane imwe nzvimbo iyo electrodes inenge iri pedyo kune imwe neimwe, ichibudisa kubuda kwekasi uye kudzokorora nzira yacho.Saka, kunyange zvazvo huwandu hwesimbi yakasvibiswa pamhepo inoyerera iduku zvikuru, simbi yakawanda inogona kuderedzwa nekuda kwezviuru zvekuputika kwemhepo pasekondi imwe neimwe, ine imwe chibereko.

Pasi pemamiriro ekuchengetedza gaka rinoramba riripo pakati pechishandiso electrode uye workpiece, simbi yeworkpiece ine corrode apo electrode yekushandisa inoramba ichiiswa mukati meiyo workpiece, uye pakupedzisira chimiro chinoenderana nechimiro chechishandiso electrode inogadzirwa. Kuora-resistant zvinhu zvine conductivity yakanaka, kunyungudika kwakakwirira uye nyore kugadzirisa, zvakadai semhangura, graphite, copper-tungsten alloy uye molybdenum.Muchigadziro chekugadzira, electrode yekushandisa inewo kurasikirwa, asi zvishoma kudarika kuwanda kwekuora kwesimbi ye workpiece, kana kunyange pedyo pasina kurasikirwa.

Sechisviniro chekubuda, mvura inoshandiswa inobatawo basa mukutonhodza uye kubviswa kwechiputi panguva yekugadzirisa.Mvura dzinoshandiswa dzinoshanda dziri pakati nechepasi viscosity, high flash point uye kushanda kwakadzikama, zvakadai separafini, deionized mvura uye emulsion.Electric spark machine imhando yekuzvida-excited discharge, maitiro ayo ndeaya anotevera: ma electrodes maviri asati apera, ma electrodes maviri asati apera. electrodes nzira, svikiro rakaputsika, ipapo spark discharge inoitika.Pamwe chete nekuparara kwemaitiro, kushorwa pakati pema electrode maviri kunoderera zvakanyanya, uye voltage pakati pe electrode inodererawo zvakanyanya.Iyo spark channel inofanira kudzimwa munguva mushure mekuchengetedzwa kwenguva pfupi (kazhinji 10-7-10-3s) kuchengetedza tambo yekupisa (kubvisa danda remhepo rinopisa). kushandura simba hakusviki pakadzika kwe electrode munguva), kuitira kuti simba remagetsi rishandiswe kune zvishoma. Maererano nechimiro che electrode yekushandisa uye hunhu hwekufamba pakati pechishandiso electrode uye workpiece, edM inogona kupatsanurwa kuita mhando shanu.Waya-yakacheka edM kucheka kwezvinhu conductive uchishandisa axially inofamba waya sechokushandisa electrode uye workpiece ichifamba pamwe nechimiro chaunoda uye saizi;Edm kukuya uchishandisa waya kana kugadzira conductive kugaya vhiri semudziyo wemagetsi ekugadzira magechi. plug gage [1], giya etc. Diki gomba kugadzirisa, pamusoro alloying, kusimba kwepamusoro uye mamwe marudzi ekugadzirisa.Edm inogona kugadzira zvinhu uye maumbirwo akaomarara kucheka neyakajairwa machining nzira.Hapana simba rekucheka panguva yekugadzira;Haiburitse burr uye yekucheka groove uye zvimwe zvinokanganisa;Chishandiso che electrode zvinhu hazvifanirwe kuoma kupfuura kugadzirwa kwemagetsi, kutungamira kushandiswa kwemagetsi; iyo yepamusoro inogadzira metamorphosis layer, iyo mune mamwe maapplication inofanira kubviswazve; Zvinonetsa kubata nekusvibiswa kwehutsi kunokonzerwa nekucheneswa uye kugadzirisa kwemvura inoshanda.
