Iyini i-Laser Cutting?
Ukusika i-laser ubuchwepheshe obusebenzisa i-laser ukusika izinto zokwakha, futhi ngokuvamile busetshenziselwa izicelo zokukhiqiza ezimbonini, kodwa futhi sekuqala ukusetshenziswa yizikole, amabhizinisi amancane, kanye nabazithandayo.Ukusika i-laser kusebenza ngokuqondisa okukhiphayo kwelaser enamandla amakhulu ngokuvamile ngokusebenzisa i-optics.I-laser optics kanye ne-CNC (ukulawula izinombolo zekhompuyutha) zisetshenziselwa ukuqondisa impahla noma i-laser beam ekhiqizwayo.Ilaser yokuhweba ejwayelekile yezinto zokusika izobandakanya isistimu yokulawula ukunyakaza ukuze ilandele i-CNC noma i-G-code yephethini ezosikwa kumpahla.I-laser beam egxilile iqondiswe kokubalulekile, okuthi bese kuyancibilika, kushiswe, kuhwamuke, noma kupheshulwe indiza yegesi, kushiye unqenqema olunokuqedwa kwekhwalithi ephezulu.Abasiki be-laser basezimbonini basetshenziselwa ukusika impahla yeshidi eliyisicaba kanye nezinto zesakhiwo namapayipi.
Kungani ama-laser asetshenziselwa ukusika?
Ama-Lasers asetshenziselwa izinhloso eziningi.Enye indlela ezisetshenziswa ngayo ukusika izingcwecwe zensimbi.Kunsimbi emnene, insimbi engagqwali, kanye nepuleti le-aluminium, inqubo yokusika i-laser inembe kakhulu, ikhiqiza ikhwalithi yokusika enhle kakhulu, inobubanzi be-kerf encane kakhulu kanye nendawo ethinta ukushisa okuncane, futhi yenza kube nokwenzeka ukusika ubujamo obuyinkimbinkimbi nezimbobo ezincane.
Iningi labantu seliyazi ukuthi igama elithi “LASER” empeleni liyisifinyezo se-Light Amplification by Stimulated Emission of Radiation.Kodwa ukukhanya kuhamba kanjani epuleti lensimbi?
Isebenza kanjani?
I-laser beam iyikholomu yokukhanya okuphezulu kakhulu, yobude obubodwa, noma umbala.Esimeni selaser ye-CO2 evamile, lobo bude beza buyingxenye ye-Infra-Red yesibonisi sokukhanya, ngakho-ke abubonakali ngeso lomuntu.Uhlaka lucishe lube yi-intshi engu-3/4 kuphela ububanzi njengoba luhamba lusuka kusithombothi selaser, esidala ugongolo, ngendlela yomshini.Ingase ibhanselwe ngezindlela ezihlukene ngezibuko eziningana, noma “ama-bender bender”, ngaphambi kokuthi igcine igxiliswe epuletini.I-laser beam egxilile idlula emgodini we-nozzle ngaphambi kokuthi ishaye ipuleti.Okunye okugeleza kuleyo nozzle bore igesi ecindezelwe, njenge-Oxygen noma iNitrogen.
Ukugxila kwe-laser beam kungenziwa ngelensi ekhethekile, noma ngesibuko esigobile, futhi lokhu kwenzeka ekhanda lokusika i-laser.I-beam kufanele igxiliswe ngokunembile ukuze ukwakheka kwendawo okugxilwe kuyo kanye nokuminyana kwamandla akuleyo ndawo kube yindilinga ngokuphelele futhi kuhambisane, futhi kugxile emlonyeni.Ngokugxilisa i-beam enkulu phansi iye endaweni eyodwa yokukhomba, ukuminyana kokushisa kuleyo ndawo kudlulele.Cabanga ngokusebenzisa ingilazi yokusondeza ukuze ugxilise imisebe yelanga eqabungeni, nokuthi lokho kungaqala kanjani umlilo.Manje cabanga ngokugxilisa ama-KWtts angu-6 endaweni eyodwa, futhi ungacabanga ukuthi leyo ndawo izoshisa kangakanani.
Ukuminyana kwamandla aphezulu kubangela ukushisa okusheshayo, ukuncibilika kanye nokuhwamuka okuyingxenye noma okuphelele kwempahla.Lapho usika insimbi emnene, ukushisa kwe-laser beam kwanele ukuqala inqubo evamile yokushiswa kwe-"oxy-fuel", futhi igesi yokusika i-laser izoba umoya-mpilo omsulwa, njengethoshi le-oxy-fuel.Lapho usikwa insimbi engagqwali noma i-aluminium, i-laser beam ivele incibilikise into, bese kusetshenziswa i-nitrogen enomfutho ophezulu ukufutha insimbi encibilikisiwe iphume ku-kerf.
Kumshini wokusika we-laser we-CNC, ikhanda lokusika i-laser lihanjiswa phezu kwepuleti lensimbi ngesimo sengxenye oyifunayo, ngaleyo ndlela kusikwa ingxenye epuletini.Isistimu yokulawula ukuphakama kwe-capacitive igcina ibanga elinembe kakhulu phakathi kwesiphetho se-nozzle nepuleti elisikwayo.Leli banga libalulekile, ngoba linquma ukuthi indawo okugxilwe kuyo ihlobene nobuso bepuleti.Ikhwalithi yokusika ingathinteka ngokuphakamisa noma ukwehlisa indawo okugxilwe kuyo ukusuka ngenhla nje kobuso bepuleti, phezulu, noma ngaphansi nje kwendawo.
Kunamapharamitha amaningi, amaningi athinta ikhwalithi yokusika futhi, kodwa lapho konke kulawulwa kahle, ukusika kwe-laser kuyinqubo yokusika ezinzile, ethembekile, futhi enembe kakhulu.
