Metalworking Electroerosive

In qeybtii hore ee qarnigii labaatanaad, saynisyahano ayaa soo jeediyay processing biraha by dhimbiil lacag. Habkani waxaa la yiraahdaa nabaad ololka. Mabda 'tallaabo processing waa mid fudud oo waa sida soo socota: in dhexdhexaad ah ee dareeraha ah dielectric la sameeyo wada ah laba electrodes tamaraysan (anode iyo cathode). Waxaa intaa dheer, doorka cathode qabanayo goosin ka mid ah shaqada. Inta u dhaxaysa anode iyo cathode ah dheecaan koronto. Inta lagu guda jiro tamarta dhexgalka la sii daayay in Kulaashaan karo iyo ka saar Qurub biraha ka dusha koronto ah. In si kale loo dhigo, waxaa jira burburka layers biraha hoos saamaynta siideeyn korontada (nabaad biraha).

By qeybinayay danab a in electrodes ee foomka of digir gaaban, tamarta galay biraha kama beddelayso. Tani waxay xaqiijineysaa in shayga inta lagu guda jiro processing ma lumin doonaa guryaha jireed.

machining dheecaan korontada. Mabda 'hawlgalka

In dhaqanka, machining ah dheecaan korontada waa sida soo socota:

1. workpiece The (cathode) ayaa lagu wadaa on miiska.
2. qalab Diyaarinta (qayb silig of copper, graphite, naxaas ah, aluminium sameeyey) machining la dusha a pre-daweeyey. dusha loo qaabeeyey waa in ay ku soo celiyaan diyaarada in la helay on workpiece ah.
3. haystaha Tool ee qaybaha guuraya ee mishiinka. Waxaa laga codsadaa in ay danab Suu qalab ah. Next, qalab ku dhowaado workpiece ah.
4. Imaanshaha "burburka" ee dielectric qaab dhimbiil oo u dhaxeeya dusha workpiece iyo qalab.
5. Aagga dhimbiil of xiriir la dusha workpiece ka dhacdaa reebtay microparticles biraha. Waxa asaasay bohol yar. Its qoto dheer waa loo siman yahay si danab u dhexeeya workpiece iyo qalab.

Waa in la ogaadaa in dhimbiil bootin u dhexeeya qaybo aad u la mid ah u dhexeeya dusha ka mid ah qalab iyo workpiece ka. Midho by malaayiin hadhuudh ah dhimbiiluhu yar yihiin laga saaro dusha biraha dhaawacan in la daweeyo. Sparks more qiyaasi dusha this qaab dusha qalab qaab rogay ah. Hannaanka waxaa si buuxda kartaa khayroon daahirnimo iyo u homogeneity of processing by beddelo kala duwanaansho danab ku qalab iyo farqiga ololka ah. Haddii loo isticmaalaa sida qalab lagu silig jaray workpiece la saxnimada sare. Intaa waxaa dheer, waxaa suurtagal ah si loo gaaro korodhka kakanaanta circuit. Marka hababka kale ee ka baaraandegidda contours adag ma laga heli karaa.

machining dheecaan korontada ee biraha leeyahay faaidooyin:

• gaaro dusha sare oo tayo sare leh machined (midayso, sax). Sidaas darteed, baahida loo qabo dhameystir dheeraad ah u baaba'aa,
• macquul ah loo helo qaabab dusha kala duwan;
• macquul obrabatyvaniya meelaha aad u adag (ka sarreeya 60 halbeeg);
• cadaadis tirtirka faahfaahsan ganaax ay sabab u la'aanta ah ee stress makaanikada,
• Duugga ugu yar ee anode ah;
• diyaarinta meelaha muuqaalada joomatari oo kala duwan;
• sanqadh lahayn inta lagu guda jiro howsha.

nabaad Spark. Isticmaalka habka of

Habka dheecaan korontada helay codsiga sida soo socota:

• dusaya godad ku yaala workpieces qalbi engegnaantiinna aawadeed kala duwan;
• formation of koriya ah;
• jarida qaybo ka mid ah engegnaantiinna kala duwan;
• saareen qaybaha qaybo madhay engejiyey,
• shiidi doona meelaha qalbi engegnaantiinna aawadeed,
• nadiifinta qaybo ka dib markii la karinayo Alloys.

EDM sidoo kale laga helay ay la isticmaalo in dayactirka ah ee mashiinada dhismaha. Iyada oo taageero ka truncation laga sameeyey qaybo ka madhay, qaybo ka jabay ka saareen qaybood ah, sii kordhaya qaybo yar madhay.

Gabagabo waa in la og yahay in ay xoog iyo cimri dherer of qaybaha mishiinka, xoojiyey habka dhimbiil oo koronto badan ku xiran tahay xaaladaha processing iyo waxyaabaha la xoojiyo.
