Niyihe gazi imashini ikata gaze cnc ikoresha?

1. Ni izihe gazi imashini ikata gaze cnc ikoresha?

Imashini ikata gazi ya cnc ni ubwoko bwibikoresho byo gutunganya bikoresha ubushyuhe bwubushyuhe bwo hejuru bwa plasma arc kugirango bishonge (kandi bigahumeka) ibyuma mugutema igihangano, kandi ikoresha imbaraga za plasma yihuta kugirango ikureho gushonga icyuma kugirango gikorwe.Oxygene ikata ibyuma bigoye gukata.Ubusanzwe ikoreshwa rya cnc imashini ikata imyuka ikora ni:

1. Umwuka

Umwuka urimo azote igera kuri 78% mubunini, kubwibyo gukora ibishishwa biterwa no gukata ikirere bisa cyane nibyo iyo ukata na azote;hiyongereyeho, umwuka urimo na 21% ogisijeni mubunini.Umuvuduko wo gukata ikirere ibikoresho byoroheje byoroheje nabyo biri hejuru cyane;icyarimwe, umwuka na gaze ikora cyane mubukungu, kandi nozzles na electrode zikoreshwa bifite ubuzima bwo hejuru.

Oxygene

Imashini ikata gaze ya cnc ikoresha ogisijeni nka gaze ikora irashobora kongera umuvuduko wo guca ibikoresho byoroheje byoroheje, ariko mugihe ogisijeni ikoreshejwe wenyine mugukata, hazabaho okiside ya dross na kerf, kandi ubuzima bwa electrode na nozzles buri hasi, ibyo bizagira ingaruka no ku mikorere myiza.no kugabanya ibiciro.

3. Argon

Gazi ya Argon ntishobora gukorana nicyuma icyo aricyo cyose mubushyuhe bwinshi, argon ikoreshwa nimashini ikata gaze ya cnc irahagaze neza, kandi nozzles na electrode zikoreshwa bifite ubuzima burebure.Nyamara, argon plasma arc ifite voltage nkeya, ubushake buke, nubushobozi buke bwo guca.Ugereranije no guca ikirere, imashini ikata gazi ya cnc izagabanya hafi 25%.Mubyongeyeho, mubidukikije byo kurinda argon, uburemere bwubuso bwicyuma gishongeshejwe ni bunini, buri hejuru ya 30% ugereranije nibidukikije bya azote, bityo hazabaho ibibazo byinshi bya slag.Ndetse imashini ya cnc ikata imashini ikata hamwe nuruvange rwa argon nizindi myuka irashobora kugira ibibazo byo gufata slag.Nkigisubizo, argon yonyine ikoreshwa gake mugukata plasma uyumunsi.

4. Hydrogen

Hydrogen isanzwe ikoreshwa nka gaze yingirakamaro kugirango ivange nizindi myuka ikoreshwa na mashini yo guca cnc.Kurugero, gaze izwi cyane H35 (igice cyinshi cya hydrogène ni 35%, naho ibindi ni argon) nimwe mumyuka ifite ubushobozi bukomeye bwo guca plasma arc, cyane cyane biterwa na hydrogen.Kubera ko hydrogène ishobora kongera ingufu za arc arc, indege ya hydrogen plasma ifite agaciro gakomeye.Iyo ivanze na argon kumashini ikata gaze ya cnc, ubushobozi bwo guca indege ya plasma buratera imbere cyane.Mubisanzwe, kubikoresho byibyuma bifite ubugari burenga 70mm, argon + hydrogen ikoreshwa.Nkugukata gaze, niba indege yamazi ikoreshwa mugukomeza guhuza argon + hydrogen plasma arc, uburyo bwiza bwo gukata nabwo burashobora kuboneka mugihe imashini ikata gaze ya cnc.

5. Azote

Azote ni gaze ikoreshwa cyane kumashini ya cnc.Hashingiwe ku mashanyarazi menshi y’amashanyarazi, azote plasma arc ifite kudakora neza ningufu zindege zirenze argon, kabone niyo uca ibikoresho byuma byamazi bifite ubukonje bwinshi nko Kubijyanye nicyuma kitagira umwanda hamwe na nikel ishingiye kuri nikel, ingano ya slagi imanikwa kumpera yo hepfo yo gukata nayo ni nto cyane mugihe cnc yo gukata imashini.Mubikorwa nyabyo byo guca, birasabwa guhitamo gaze ikora ya mashini yo guca gaze cnc ukurikije ibyo usabwa kugabanya nigiciro cyubukungu.

Icya kabiri, imashini ikata ikirere gisabwa umwuka

Imashini ikata ikirere, nkuko izina ribigaragaza, ni imashini ikata plasma ikoresha umwuka nka gaze ikora.Imashini ikata gaze ya cnc ifite ibyo isabwa kugirango umwuka ukoreshwe:

Umwuka ukoreshwa na mashini ikata gazi ya cnc ni umwuka wugarijwe, bisaba ko gaze yumye kandi yera, kandi umuvuduko nigitutu gihamye, kuko mugihe cyo gutema bisanzwe imashini ikata gaze cnc, umuvuduko wa gaze , umwuka uhagaze neza, hamwe no gukama nubuziranenge bwa gaze bigira ingaruka itaziguye.Ubwiza bwa cnc yo gukata imashini ikata kandi niba arc ishobora gutangira bisanzwe.Mubisanzwe, birashobora kugenzurwa nuburyo bukurikira:

1. Reba niba igipimo cyumuvuduko wumwuka kuri cnc imashini itema.Niba imashini itema gaze ya cnc, nyamuneka hindura buto yo guhindura umwuka kugirango wongere umuvuduko wumwuka.

2. Reba niba umwuka utemba kuri mashini ikata gazi ya cnc nibisanzwe, fungura icyerekezo cyo kurekura ikirere kugirango uhindure kugirango urebe niba igipimo cyumuvuduko wumwuka ugabanuka, niba igitonyanga ari kinini, bivuze ko umuvuduko wumuyaga udahagije , noneho ikigega cyo kubika gaze kigomba kongerwaho imbere yimashini ikata gaze cnc kugirango hamenyekane gazi;

3. Reba niba gaze yumye kandi yera, kanda hepfo yumutungo wamazi wamazi ya cnc imashini ikata, hanyuma ubireke.Niba hari amazi menshi yera muri gaze yarekuwe, bivuze ko mu kirere hari amavuta menshi n'amazi menshi.Ubu bwoko bwumwuka ntibukwiye gukoreshwa.
