Electroerosive zokhomakhoma

Mu zoyambirira za mazana makumi awiri, asayansi akufuna chitsulo processing ndi mlandu kuthetheka. njira imeneyi imatchedwa mphanvu kukokoloka. processing kanthu mfundo yosavuta chiri motere: mu madzi dielectric sing'anga wapangidwa mgwirizano wa maelekitirodi awiri amayesetsa (anode ndi cathode). Komanso, udindo wa cathode amene akuchita chidutswa cha ntchito. Pakati pa anode ndi cathode ndi kumaliseche magetsi. Pa mphamvu mogwirizana adzamasulidwa kuti akhoza konzekera ndi kuchotsa zitsulo particles kuchokera pamwamba elekitirodi. M'mawu ena, pali chiwonongeko cha zigawo zitsulo pansi zotsatira za kukha magetsi (zitsulo kukokoloka).

Popereka ndi voteji kwa maelekitirodi mu mawonekedwe a nyemba lalifupi, mphamvu mu zitsulo si bwanji. Izi zipangitsa kuti katunduyo pa processing sadzatayikiridwa katundu lawo.

Magetsi kumaliseche Machining. Mfundo ntchito

Zochita za Machining magetsi kumaliseche ali motere:

1. The workpiece (cathode) pamwamba pa tebulo.
2. Kukonzekera chida Machining (waya mbali za mkuwa, graphite, mkuwa, zitsulo zotayidwa) ndi chisanadze mankhwala pamwamba. pamwamba ayenera zooneka kubwereza ndege kupeza pa workpiece lapansi.
3. Chida chofukizira mbali yoyamikira makina. Kugwiritsidwa ntchito pa chida mopupuluma voteji. Kenako, chida akuyandikira workpiece.
4. Maonekedwe "chipasuko" wa dielectric mu mawonekedwe a mphanvu pakati padziko workpiece ndi chida.
5. Mphamvu zone kucheza ndi pamwamba workpiece zimachitika kugogoda zitsulo microparticles. Anapanga Chigwa yaing'ono. kuya kwake ndi wofanana ndi voteji pakati pa workpiece ndi chida.

Tikumbukenso kuti ngati nthethe kudumpha pakati pa mbali zofanana kwambiri pakati pamwamba chida ndi workpiece. Mapira ambiri nsakali yaing'ono mbewu achotsedwa padziko zowonongeka zitsulo kuchitiridwa. Nsakali kwambiri kuyandikira pamwamba mu mawonekedwe kwa chida pamwamba mu mawonekedwe kukalowa. Dongosololi akhoza kudzapeza chiyero ndi homogeneity wa processing ndi kusintha voteji kusintha pa chida ndi kusiyana kuthetheka. Ngati ntchito ngati chida cha waya kudula workpiece molondola apamwamba. Komanso, n'zotheka kuti tikwaniritse bwino dera kwambiri. Pamene njira zina processing contours zovuta sungagulire.

Magetsi kumaliseche Machining zitsulo angapo ubwino:

• kukwaniritsa apamwamba machined padziko (pachilichonse molondola). Choncho, panafunika kumalizitsa zina Mwamsanga;
• n'zotheka kupeza mawonekedwe osiyana pamwamba;
• Kuthekera obrabatyvaniya pamalo zovuta kwambiri (pamwamba 60 mayunitsi);
• kufufutidwa kupsyinjika chabwino mwatsatanetsatane chifukwa chosowa nkhawa mawotchi;
• osachepera avale wa anode ya;
• yokonza pamalo wamitundu yosiyanasiyana geometrical;
• phokoso pa processing.

Kuthetheka kukokoloka. Pogwiritsa ntchito njira

Magetsi kumaliseche njira anapeza ntchito kwake motere:

• kuboola mabowo workpieces wa kuuma osiyana;
• mapangidwe zamkati ndi;
• kudula ziwalo za kuuma osiyana;
• kuchotsa mbali ankavala mbali anaumitsa;
• akupera pamalo wa kuuma uliwonse;
• kukonza mbali pambuyo kasakaniza wazitsulo kuphika.

EDM anapezanso ntchito mu yokonza makina yomanga. Mothandizidwa ndi truncation unapangidwa mbali olema, mbali wosweka kuchotsa fasteners, kuwonjezeka mbali pang'ono ankavala.

Pomaliza tiyenera zidziwike kuti mphamvu ndi durability mbali makina, analimbitsa magetsi mphanvu njira kumadalira zikhalidwe processing ndi mfundo ikuthandizira.
