Ukusebenza Electroerosive

Engxenyeni yokuqala yekhulu lamashumi amabili, ososayensi baye basikisela processing metal by icala inhlansi. Le nqubo ibizwa ngokuthi inhlansi ukuguguleka kwenhlabathi. ukucutshungulwa isinyathelo isimiso ilula futhi simi ngale ndlela: in the ketshezi naphakathi Kwe-dielectric Heating senziwa Kuhlanganiswe electrode amabili akukhuthalele (anode futhi cathode). Ngaphezu kwalokho, indima yokuba cathode wenza ucezu umsebenzi. Phakathi anode kanye cathode i osenyameni kagesi. Phakathi amandla ukuxhumana ikhishwe ezingaba kulungele futhi ususe metal izinhlayiya ebusweni electrode. Ngamanye amazwi, kukhona ukubhujiswa izingqimba lensimbi ngaphansi umphumela esithweni kagesi (ukuguguleka metal).

Ngu kokunikeza voltage kuya electrode ngesimo pulses esifushane, amandla phakathi metal ayiphazamiseki. Lokhu kuqinisekisa ukuthi le nto phakathi kwenqubo ngeke ulahlekelwe nezici zabo ezingokomzimba.

Kagesi osenyameni machining. Umgomo we operation

Ekusebenteni, kagesi osenyameni machining simiswe ngalendlela lelandzelako:

1. Workpiece (cathode) isethwe etafuleni.
2. ithuluzi Ukulungiselela for machining (wire ingxenye ezazenziwe ngethusi, graphite, nethusi, aluminium) ngenhloso ngaphandle pre-ngayo. Ebusweni kufanele ezimise ukuphinda indiza ukutholwa ku workpiece.
3. Ithuluzi umnikazi e izingxenye ezinyakazayo umshini. It isetshenziswa voltage ithuluzi ungacabanganga. Ngokulandelayo, ithuluzi osondela workpiece.
4. Ukubukeka "nokwaphuka 'ka Kwe-dielectric Heating ngesimo ube yinhlansi phakathi ebusweni workpiece futhi ithuluzi.
5. Izoni inhlansi ukuxhumana surface workpiece kwenzeka ongqongqozayo metal microparticles. Kwakheka emgodini omncane. Ukujula kwawo ilingana voltage phakathi workpiece futhi ithuluzi.

Kufanele kuqashelwe ukuthi ube yinhlansi kuzuba phakathi izingxenye ezithi azifane phakathi ebusweni ithuluzi kanye workpiece. Uhlamvu ngohlamvu izigidi izinhlansi encane isuswa obonakele ebusweni metal ngayo. Sparks ngaphezulu esondele lokhu ebusweni ifomu kwamanzi ithuluzi ngefomu nabokhulumile. Inqubo ngeke ukukhulisa nobumsulwa homogeneity ukucutshungulwa ngokushintsha ukushintshashintsha voltage ithuluzi futhi igebe inhlansi. Uma ithuluzi for the wire usike workpiece ngokunemba ephakeme. Ngaphezu kwalokho, kungenzeka ukuba sifinyelele okhushuliwe wesifunda eyinkimbinkimbi. Lapho ezinye izindlela zokuhlela wabuka eziyinkimbinkimbi ngeke kutholakale.

osenyameni agesi machining of izinsimbi kunezinzuzo eziningana:

• ekufezeni eliphezulu ebusweni ngomshini (ukufana, ukunemba). Ngakho, isidingo yokuqedela okwengeziwe ubalekela;
• kungenzeka yokuthola ezahlukene ebusweni ukwakheka;
• kungenzeka obrabatyvaniya evele kanzima kakhulu (amayunithi ngenhla 60);
• ukususwa uhlobo imininingwane emihle ngenxa yokuntuleka ukucindezeleka mechanical;
• bafake okungenani anode;
• ukulungiselela ezishelelayo tabobunjwa yejeyomethri;
• kungekho msindo ngesikhathi ukucubungula.

Spark ukuguguleka kwenhlabathi. Ukusebenzisa indlela

Kagesi osenyameni indlela atholakala yayo isicelo kanje:

• Ukubhoboza izimbobo workpieces of ubulukhuni ezahlukene;
• kumiswa kude;
• ukusika izingxenye ubulukhuni ezahlukene;
• Ukususa bakhathale izingxenye saphenduka izingxenye;
• ukugaya evele of yimuphi ubulukhuni;
• ukuhlanza izingxenye emva ukupheka Alloys.

EDM futhi wathola elisetshenziswa ukukhanda of ukwakhiwa imishini. Ngosizo akhronimi wenziwe bakhathale izingxenye, ephukile izingxenye Ukususa iziqobosho, elandayo kancane bakhathale izingxenye.

Ekuphetheni it azi ukuthi amandla ukuqina izingxenye zemishini, kwagcizelela inhlansi kagesi indlela kuxhomeke kakhulu izimo ukucutshungulwa kanye impahla abalwazi kahle ulimi.
