Ukunemba kwe-Laser cutting ngokuvamile kuthinta ikhwalithi yenqubo yokusika. Uma ukunemba komshini wokusika we-laser kuphambuka, ikhwalithi yomkhiqizo osikiwe izobe ingafanelekile. Ngakho-ke, indlela yokuthuthukisa ukunemba komshini wokusika we-laser kuyinkinga eyinhloko yabasebenzi bokusika i-laser.
1. Kuyini ukusika i-laser?
Ukusika i-laser ubuchwepheshe obusebenzisa i-laser density high-power density njengomthombo wokushisa futhi kwenze ukusika ngokunyakaza okuhlobene ne-workpiece. Umgomo wayo oyisisekelo uthi: ugongolo lwe-laser olunamandla amakhulu lukhishwa i-laser, futhi ngemva kokugxila ohlelweni lwe-optical path, lukhanyiselwa phezu kwendawo yokusebenza, ukuze izinga lokushisa le-workpiece liphakanyiswe khona manjalo izinga lokushisa liphakeme kunephuzu lokuncibilika elibalulekile noma indawo yokubilisa. Ngasikhathi sinye, ngaphansi kwesenzo somfutho wemisebe ye-laser, uhla oluthile lwegesi enomfutho ophezulu luyakhiqizwa eduze kwendawo yokusebenza ukuze kukhishwe insimbi encibilikisiwe noma ehwamuke, futhi ama-pulses okusika angaphuma ngokuqhubekayo phakathi nenkathi ethile yesikhathi. Njengoba ukuma okuhlobene kwe-beam kanye ne-workpiece inyakaza, ekugcineni kwakhiwa i-slit ukuze kuzuzwe injongo yokusika.
Ukusika i-laser akunawo ama-burrs, imibimbi, nokunemba okuphezulu, okungcono kunokusika i-plasma. Ezimbonini eziningi zokukhiqiza i-electromechanical, izinhlelo zesimanje zokusika i-laser ezinezinhlelo zamakhompiyutha amancane zingasika kalula izingcezu zokusebenza ezinomumo nosayizi abahlukene, ngakho-ke zivame ukuncanyelwa kunezinqubo zokubhoboza kanye nokucindezela ukufa. Nakuba ijubane layo lokucubungula lihamba kancane kune-die punching, ayidli isikhunta, ayidingi ukulungisa isikhunta, futhi yonga isikhathi sokushintsha isikhunta, ngaleyo ndlela ilondoloze izindleko zokucubungula nokunciphisa izindleko zomkhiqizo. Ngakho-ke, iyonga kakhulu ngokujwayelekile.
2. Izici ezithinta ukunemba kokusika
(1) Usayizi wendawo
Phakathi nenqubo yokusika umshini wokusika we-laser, i-beam yokukhanya igxile ekugxilweni okuncane kakhulu nge-lens yekhanda lokusika, ukuze ukugxila kufinyelele amandla aphezulu. Ngemva kokugxila kwe-laser, kwakhiwa indawo: indawo encane ngemva kokugxila kwe-laser, kuphakama ukunemba kokucubungula kwe-laser.
(2) Ukunemba kwebhentshi lokusebenzela
Ukunemba kwebhentshi lokusebenzela ngokuvamile kunquma ukuphindaphinda kokucutshungulwa kwe-laser. Ukuphakama kokunemba kwebhentshi lokusebenzela, kukhuphuka ukunemba kokusika.
(3) Ukujiya kocwecwe
Ukuqina kwe-workpiece okufanele kusetshenzwe, kuyancipha ukunemba kokusika kanye nokuqhekeka okukhulu. Njengoba i-laser beam i-conical, i-slit nayo i-conical. I-slit yempahla ezacile incane kakhulu kunento ewugqinsi.
(4) Impahla yokusebenza
I-workpiece material inethonya elithile ekunembeni kwe-laser cutting. Ngaphansi kwezimo ezifanayo zokusika, ukunemba kokusika kwama-workpieces wezinto ezahlukene kuhluke kancane. Ukunemba kokusika kwamapuleti ensimbi kuphakeme kakhulu kunezinto zethusi, futhi indawo yokusika ilula.
3. Ubuchwepheshe bokulawula indawo yokugxila
Uma kuncane ukujula okugxilile kwelensi egxilile, kuncane ukujula kwendawo okugxilwe kuyo. Ngakho-ke, kubaluleke kakhulu ukulawula isikhundla sokugxila okuhlobene nobuso bezinto ezisikiwe, ezingathuthukisa ukunemba kokusika.
4. Ubuchwepheshe bokusika nokubhoboza
Noma yibuphi ubuchwepheshe bokusika okushisayo, ngaphandle kwezimo ezimbalwa lapho bungaqala khona kusukela onqenqemeni lwepuleti, ngokuvamile kudinga umgodi omncane ozoshaywa epuleti. Ngaphambilini, emshinini oyinhlanganisela ye-laser stamping, i-punch yayisetshenziselwa ukubhoboza imbobo kuqala, bese i-laser isetshenziselwa ukuqala ukusika imbobo encane.
5. Idizayini ye-nozzle kanye nobuchwepheshe bokulawula ukugeleza komoya
Lapho insimbi isika i-laser, umoya-mpilo kanye ne-laser beam egxilile idutshulwa kuzinto ezisikiwe ngombhobho, ngaleyo ndlela kwakheka i-airflow beam. Izidingo eziyisisekelo zokugeleza komoya ukuthi ukugeleza komoya okungena endaweni yokusikwa kufanele kube kukhulu futhi isivinini kufanele sibe phezulu, ukuze i-oxidation eyanele ikwazi ukusabela ngokuphelele kwe-exothermic yezinto ezisikiwe; ngesikhathi esifanayo, kunomfutho owanele wokukhipha izinto ezincibilikisiwe.
