Ni ukubera iki igikoresho gito cyo gupima ibikoresho hamwe nibikorwa bya degassing byongeweho ibyiza byubwinshi buke bwa PU elastomers
Igicapo gikozwe mubikoresho byayobora gicibwa ukoresheje plasma yihuta ya plasma yindege.Ni uburyo bwiza bwo guca ibyuma byimbitse.
Waba urimo ukora ibihangano cyangwa gukora ibicuruzwa byarangiye, gukata plasma bitanga amahirwe atagira imipaka yo guca aluminium nicyuma kitagira umwanda.Ariko niki kiri inyuma yubu buhanga bushya ugereranije? Twasobanuye ibibazo byingenzi mubisobanuro bigufi, bikubiyemo ibintu byingenzi byerekeranye na plasma imashini zo gukata no gukata plasma.
Gukata plasma ni inzira yo guca ibikoresho bitwara hamwe nindege yihuse ya plasma yumuriro.Ibikoresho bisanzwe bishobora gutemwa nu muriro wa plasma ni ibyuma, ibyuma bitagira umwanda, aluminium, umuringa, umuringa, nibindi byuma bitwara.Gukata plasma bikoreshwa cyane mubikorwa , gufata neza imodoka no kuyisana, kubaka inganda, salvage no gusiba. Bitewe n'umuvuduko mwinshi wo kugabanya, neza cyane kandi bihendutse, gukata plasma birakoreshwa cyane, kuva mubikorwa binini bya CNC byinganda kugeza kumasosiyete mato mato, kandi ibikoresho bikoreshwa mugusudira. .Gukata plasma-Gazi ikora nubushyuhe bugera kuri 30.000 ° C ituma gukata plasma bidasanzwe.
Inzira y'ibanze yo gukata plasma no gusudira ni ugukora umuyoboro w'amashanyarazi wa gaze ya ioniside ishyushye cyane (ni ukuvuga plasma), uhereye kumashini ikata plasma ubwayo ukoresheje igicapo cyo gukata, bityo ugakora uruziga rwuzuye rusubira mumashini ikata plasma binyuze muri Ubutaka.Ibi bigerwaho no guhuha gaze ifunitse (ogisijeni, umwuka, gaze ya inert nizindi myuka, bitewe nibikoresho bigomba gutemwa) binyuze mumatongo yibanze ku muvuduko mwinshi ugana ku kazi. Muri gaze, hakozwe arc hagati ya electrode hafi ya gaze nozzle hamwe nakazi kayo ubwako.Iyi arc ionize igice cya gaze kandi ikora umuyoboro wa plasma uyobora. ya plasma yihuta cyane na gaze isunitswe ihanagura icyuma gishongeshejwe, gitandukanya igihangano.
Gukata plasma nuburyo bwiza bwo gukata ibikoresho bito kandi binini. Amatara afashe mu ntoki arashobora guca ibyuma 38 mm byibyuma byibyuma, kandi amatara akomeye agenzurwa na mudasobwa arashobora guca ibyuma byibyuma bya mm 150.Kuko imashini zikata plasma zitanga ubushyuhe bwinshi kandi cyane “cones” yaho yo gukata, ni ingirakamaro cyane mugukata no gusudira impapuro zigoramye cyangwa zinguni.
Imashini zikata intoki zikoreshwa muri rusange zikoreshwa mugutunganya ibyuma bito, gutunganya uruganda, gufata neza ubuhinzi, gusana gusudira, ibigo bitanga ibyuma (gusiba, gusudira no gusenya), imishinga yubwubatsi (nk'inyubako n'ibiraro), kubaka ubwato bwubucuruzi, gukora romoruki, imodoka gusana Kandi ibihangano (gukora no gusudira).
Imashini zikata plasma zikoreshwa mubisanzwe nini cyane kuruta imashini zikata plasma kandi zikoreshwa zifatanije nimbonerahamwe yo gukata.Imashini yo gukata plasma yimashini irashobora kwinjizwa muri sisitemu yo gukata kashe, laser cyangwa robotic.Ubunini bwimashini ikata plasma yimashini biterwa na imbonerahamwe na portal byakoreshejwe.Iyi sisitemu ntabwo yoroshye gukora, kubwibyo byose hamwe nibisobanuro bya sisitemu bigomba gutekerezwa mbere yo kwishyiriraho.
Muri icyo gihe, uwabikoze atanga kandi igice gikomatanyije gikwiye gukata no gusudira.Mu rwego rwinganda, itegeko ryikiganza ni: uko bigoye ibisabwa byo guca plasma, nigiciro cyinshi.
Gukata plasma byagaragaye mu gusudira kwa plasma mu myaka ya za 1960 kandi byateye imbere muburyo bunoze bwo guca ibyuma n'amasahani mu myaka ya za 1980. Ugereranije no gukata “icyuma-kucyuma”, gukata plasma ntabwo bitanga icyuma kandi bitanga gukata neza. Imashini zo gukata plasma zambere zari nini, zitinda kandi zihenze.Niyo mpamvu, zikoreshwa cyane mugusubiramo uburyo bwo gutema muburyo bwo gukora cyane.Nkindi bikoresho byimashini, tekinoroji ya CNC (kugenzura numero ya mudasobwa) yakoreshejwe mumashini yo guca plasma guhera mumpera za 1980 kugeza mu myaka ya za 90.Murakoze ku buhanga bwa CNC, imashini ikata plasma yarushijeho guhinduka mugukata imiterere itandukanye ukurikije urukurikirane rw'amabwiriza atandukanye yateguwe muri sisitemu ya CNC ya mashini.Nyamara, imashini zo guca plasma za CNC mubusanzwe zigarukira gusa ku gutema ibice n'ibice biva icyuma kibase gifite amashoka abiri gusa.
Mu myaka icumi ishize, abakora imashini zitandukanye zo gukata plasma bakoze moderi nshya zifite nozzles ntoya na plasma arc yoroheje.Ibi bituma plasma yo guca inkombe igira ibisobanuro bisa na laser.Abakora inganda nyinshi bahujije kugenzura neza CNC nimbunda zo gusudira kugirango babone umusaruro ibice bisaba bike cyangwa ntagikorwa, koroshya izindi nzira nka gusudira.
Ijambo "gutandukanya ubushyuhe" rikoreshwa nkijambo rusange muburyo bwo gutema cyangwa gukora ibikoresho hakoreshejwe ubushyuhe.Kubijyanye no guca cyangwa kutagabanya umwuka wa ogisijeni, nta mpamvu yo gukomeza gutunganywa mugutunganya neza.Ibikorwa bitatu byingenzi ni oxy-lisansi, plasma no gukata laser.
Iyo hydrocarbone iba oxyde, itanga ubushyuhe. Kimwe nubundi buryo bwo gutwika, gukata oxy-lisansi ntibisaba ibikoresho bihenze, ingufu ziroroshye gutwara, kandi inzira nyinshi ntizisaba amashanyarazi cyangwa amazi akonje.Icyuma kimwe na silindiri imwe mubisanzwe birahagije. Gukata lisansi ya Oxygene ninzira nyamukuru yo guca ibyuma biremereye, ibyuma bitavanze nicyuma gito, kandi bikoreshwa mugutegura ibikoresho byo gusudira nyuma. Nyuma yumuriro wa autogenous uzana ibikoresho mubushyuhe bwo gutwika, indege ya ogisijeni irahindurwa kuri hamwe nibikoresho byaka.Umuvuduko ubushyuhe bwo gutwika bugerwaho biterwa na gaze.Umuvuduko wo gukata neza biterwa nubuziranenge bwa ogisijeni n'umuvuduko wo guterwa na ogisijeni. umusaruro mwinshi no kugabanya ikiguzi rusange.
Gukata plasma byakozwe mu myaka ya za 1950 bigamije gukata ibyuma bidashobora kurasa (nk'ibyuma bitagira umwanda, aluminium, n'umuringa) .Mu gukata plasma, gaze muri nozzle ionion kandi yibanda ku gishushanyo cyihariye cya nozzle. Gusa hamwe nibi umugezi wa plasma ushyushye urashobora gukata ibikoresho nka plastiki bigabanywa (nta kwimura arc) .Kubikoresho byicyuma, gukata plasma nabyo bitwika arc hagati ya electrode nakazi ko gukora kugirango byongere ingufu.Gufungura nozzle ifunganye cyane yibanda kuri arc na plasma.An guhuza kwinyongera yinzira yo gusohora birashobora kugerwaho na gaze yingoboka (gazi ikingira) .Guhitamo plasma ikwiye / ikingira gaze irashobora kugabanya cyane ikiguzi cyibikorwa byose.

Gukata Laser nubuhanga bugezweho bwo gukata amashyuza, bwakozwe nyuma yo gukata plasma.Ibiti bya lazeri bibyara mu cyuho cya resonant ya sisitemu yo gukata lazeri.Nubwo ikoreshwa rya gaze ya resonator iri hasi cyane, ubuziranenge bwayo nibigize neza birakomeye.Resonator idasanzwe igikoresho cyo gukingira gaze cyinjira mu cyuho cya resonant kiva muri silinderi kandi kigahindura imikorere yo gutema.Ku gukata no gusudira, urumuri rwa laser ruyoborwa kuva kuri resonator kugera kumutwe uciye binyuze mumihanda yinzira.Bigomba kwemezwa ko sisitemu idafite umusemburo. . bisa no gukata oxy-lisansi.Dore, ubuziranenge bwa ogisijeni nabwo bugira uruhare runini.Nitrogen ikoreshwa mubyuma bitagira umwanda, aluminium, na nikel bivanze kugirango bigere kumpande zisukuye kandi bigumane ibintu byingenzi bya substrate.
Amazi akoreshwa nka coolant mubikorwa byinshi byinganda bizana ubushyuhe bwinshi mubikorwa.Ni no muburyo bwo gutera amazi mugukata plasma. Amazi yatewe muri plasma arc yimashini ikata plasma akoresheje indege.Iyo ukoresheje azote nka plasma gaze, plasma arc isanzwe ikorwa, niko bigenda kumashini nyinshi zo guca plasma. Amazi amaze guterwa muri plasma arc, bizatera kugabanuka k'uburebure. Muri ubu buryo bwihariye, ubushyuhe bwazamutse cyane bugera kuri 30.000 ° C no hejuru. Niba ibyiza byimikorere yavuzwe haruguru bigereranijwe na plasma gakondo, birashobora kugaragara ko ubwiza bwo gutema hamwe nurukiramende rwo gutema byatejwe imbere kuburyo bugaragara, kandi ibikoresho byo gusudira byateguwe neza. Usibye kunoza uburyo bwo guca ubuziranenge mugihe cya plasma gukata, kwiyongera kugabanya umuvuduko, kugabanuka kwikubye kabiri, no kugabanuka kw isuri ya nozzle nabyo birashobora kugaragara.
Gazi ya Vortex ikoreshwa kenshi munganda zogukata plasma kugirango igere kubintu byiza byinkingi ya plasma hamwe nijosi rihamye rihamye.Nkuko umubare wimyuka ya gazi winjira wiyongera, imbaraga za centrifugal zimura ingingo yumuvuduko mwinshi kugera kumpera yicyumba cyumuvuduko ukagenda. igitutu ntarengwa cyegereye uruzitiro. Itandukaniro riri hagati yumuvuduko ntarengwa nuwinshi wiyongera hamwe numubare wa vortice.Itandukaniro rinini ryumuvuduko mubyerekezo bya radiyo rigabanya arc kandi ritera ubucucike buri hejuru hamwe nubushyuhe bwa ohmic hafi yigitereko.
Ibi biganisha ku bushyuhe bwo hejuru cyane hafi ya cathode. Twabibutsa ko hari impamvu ebyiri zituma gaze ihindagurika yihutisha kwangirika kwa cathode: kongera umuvuduko mubyumba byotswa igitutu no guhindura uburyo bwo gutembera hafi ya cathode.Bikwiye kandi tekereza ko, ukurikije kubungabunga imbaraga zinguni, gaze ifite numubare munini wa vortex izongera ibice byumuvuduko wa vortex mugihe cyo gukata.Bikekwa ko ibyo bizatera inguni yibumoso niburyo bwibice byaciwe kuba bitandukanye.
Duhe ibitekerezo kuriyi ngingo. Ni ibihe bibazo bitarasubizwa, kandi ushishikajwe niki? Igitekerezo cyawe kizadufasha kurushaho kuba beza!
