Uyu munsi turaganira kubikoresho bya electro-spark ikoreshwa mubyuma bivangwa nicyuma, mugihe kimwe tuzibanda kuri tekinoloji yukuntu twahindura ibumba mubikoresho byo gutera inshinge no guterera.
Kubitsa Electro-Spark Niki?
Ubuvuzi bwa electro-spark, buzwi kandi ku izina rya Electro-gusohora imashini (EDM), ni uburyo bwihariye bwo gukora bukubiyemo gukoresha amashanyarazi mu buryo bwo guhindura no guhindura ubuso bw'ibyuma.
Mugihe cyo kuvura Electro-spark, isohoka ryamashanyarazi rikorwa hagati ya electrode nigikorwa cyakazi, mubisanzwe bikozwe mubikoresho bitwara ibyuma nkibyuma cyangwa amavuta.Inzira itangira ushyira electrode, akenshi muburyo bwigikoresho gito, giteye, hafi yakazi.
Iyo voltage ikoreshejwe hagati ya electrode nakazi kakazi, urukurikirane rwamashanyarazi rwihuta ruba.Ibyo bisohora bitera ubushyuhe bukabije, gushonga uduce duto twubuso bwakazi.Icyuma gishongeshejwe noneho kizimya vuba na dielectric fluid, bigatuma gikomera kandi kigakora utwobo duto cyangwa indentations.
ESD ikoreshwa mubyuma bivanze
Iyo ingufu za capacitor zirekuwe, umuyaga utaziguye ukora ubushyuhe bwo hejuru bwa plasma arc hagati ya tip ya electrode hamwe nicyuma gikora icyuma.Ubu bushyuhe bwo hejuru buri hagati ya 8000 na 25000 ° C.Plasma arc ionize anode kandi ihererekanya byihuse ibikoresho byashongeshejwe kumurimo.
Iyi ionizing anode yimuriwe muri substrate ikoresheje pulses ngufi.Ubushyuhe bwo hejuru arc bugizwe nuduce twa anode, imigezi yubushyuhe (jet ishyushye), hamwe na plasma yatewe no kubora gaze na atome zikora za azote, ogisijeni, na karubone.Ubushyuhe bwinshi butwarwa nindege yumuriro na plasma.
Kuberako impiswi ari ngufi, guhererekanya ubushyuhe binyuze mu ndege yubushyuhe hamwe nizindi myuka ni nto, kandi ihererekanyabubasha ryonyine kuri substrate ni binyuze mumubare muto wa anode zashyizwe kuri substrate.Kubwibyo, iyi pulses yimura ubushyuhe buke kuri substrate idahinduye microstructure ya substrate.Ubu buryo ni bwiza kuruta uburyo bwo gusudira bwa fusion busanzwe bukoreshwa mugusana ibishishwa hamwe nubutaka bubi bwibasiwe nubushyuhe (urugero, ubukana buke, ubukana bwinshi, gucamo amazi).
Ikigeretse kuri ibyo, inzira ifasha kurema umurunga ukomeye hagati ya substrate no gutwikira.Microalloying hagati ya electrode yashonga na substrate itangira gukora plasma binyuze mukwangirika kwikirere, karubone, karbide na nitride.
Ibyiza
1.Ibisobanuro nukuri: Kuvura electro-spark itanga uburyo bunoze kandi bwuzuye bwibintu bisobanutse hamwe nibintu bigoye hejuru yicyuma.Amashanyarazi agenzurwa asohora ibintu muburyo bugenzurwa, bigafasha kurema ibintu bisobanutse nkibyobo bito, ibibanza, cyangwa ibyerekezo bifite uburinganire buringaniye.
2.Kuzigama Ubunyangamugayo bwibintu: Kimwe mubyiza byingenzi byo kuvura Electro-spark nubushobozi bwayo bwo kubungabunga ubukana nubusugire bwakazi.Bitandukanye nuburyo gakondo bwo gutunganya bushobora kubyara ubushyuhe bukabije kandi bugatera impinduka zidakenewe mubintu bifatika, kuvura amashanyarazi-bigabanya uturere twibasiwe nubushyuhe kandi bikagumana ubukana bwakazi hamwe nuburinganire bwimiterere.
3.Complex Geometrie: Kuvura amashanyarazi-spark ituma gutunganya geometrike igoye ishobora kuba ingorabahizi cyangwa idashoboka kubigeraho hamwe nuburyo busanzwe bwo gutunganya.Ubushobozi bwayo bwo gukora ibintu bigoye bituma habaho kubyara ibishushanyo, bipfa, cyangwa ibindi bice bifite imiterere yihariye nibisobanuro birambuye, kwagura ibishushanyo mbonera.
4.Nta bikoresho byo kwambara: Bitandukanye nuburyo gakondo bwo gutunganya burimo gukata cyangwa gukuramo, kuvura Electro-spark ntabwo bikubiyemo guhuza bitaziguye nigikoresho nakazi.Nkigisubizo, hari ibikoresho bike byambara, biganisha kubikoresho byongerewe ubuzima no kugabanya amafaranga yo kubungabunga.
Incamake
Iyi ngingo itangiza cyane cyane gahunda ya EDM muburyo bwo gukora ibishushanyo, ntabwo itangiza inzira zayo gusa, ahubwo inerekana inyungu nyamukuru ziki gikorwa.Binyuze kuri videwo yavuzwe haruguru, nizere ko ushobora gusobanukirwa neza inzira.Niba ufite ibindi bibazo, nyamuneka wumve nezatwandikire.
