Izikhundla ezihlukahlukene zokugxila zivame ukuholela emazingeni ahlukene obucayi bezinto zokusika, i-slag ehlukene ilenga phansi, ngisho nezinto azikwazi ukusikwa;i-workpiece yokusika ihlukile, futhi ibanga phakathi kokugxila kwe-laser kanye nezinto zokusika kufanele zilungiswe ngaphambi kokusika noma iyiphi into..Okuhlukile, isikhundla sokugxila kwe-umshini wokusika i-fiberzizohluka, ngakho-ke ungakhetha kanjani ngendlela efanele?
Incazelo yendawo yokugxila: Ibanga elisuka lapho kugxilwe khona liye endaweni engaphezulu yesiqeshana sokusebenza sokusika.Indawo okugxilwe kuyo ngaphezu kwendawo yokusebenza ngokuvamile ibizwa ngokuthi i-positive focus, futhi indawo okugxilwe kuyo ngaphansi kwendawo yokusebenza ngokuvamile ibizwa ngokuthi i-negative focus.
Ukubaluleka kwendawo okugxilwe kuyo: Ukushintsha indawo okugxilwe kuyo kusho ukushintsha usayizi wendawo ngaphakathi nangaphakathi ebhodini, ubude bokugxila buba bukhulu, indawo iba nkulu, umkeke uba banzi futhi ube banzi, futhi ukuzaca kuthinta indawo yokushisisa, ukuqhekeka. usayizi nokukhishwa kwe-slag.
Positive focus cutting
Ngokusika i-carbon steel oxygen, ukwamukela ukugxila okuhle, isilinganiso esiphansi se-workpiece, kanye nobubanzi bokusika bendawo engaphezulu kuyasiza ekuphumeni kwe-slag, futhi kunenzuzo ukuthi umoya-mpilo ufinyelele phansi kwendawo yokusebenza ukuze ubambe iqhaza ngokugcwele. ukusabela kwe-oxidation.Ngaphakathi kwebanga elithile lokugxila, usayizi wokugxila okuhle, ubukhulu bendawo endaweni yebhodi, ukushisa kwangaphambili okuzungeze umphetho kanye nokufaka esikhundleni nokwengeza kwanele, ukuba bushelelezi futhi kukhanye indawo yokusika i-carbon steel.Le ndlela isebenzisa insimbi engagqwali ukusika ipuleti lensimbi eliwugqinsi eligxilile, ukusika okuzinzile, okuhle ekukhishweni kwe-slag futhi okunzima ukukhombisa ukukhanya okuluhlaza okwesibhakabhaka.
I-Negative focus cutting
Okusho ukuthi, ukugxila kokusika kuse-workpiece.Kule modi, ngoba ibanga eligxile lisuka endaweni yokusika, ububanzi bokusika bukhulu kakhulu kunephuzu lokusika endaweni yokusebenza.Ngesikhathi esifanayo, ukugeleza komoya okusika kukhulu futhi izinga lokushisa lanele.Lapho usika insimbi engagqwali, kwamukelwa ukugxila okungalungile, futhi indawo yokusika ithungwa ngokulinganayo.
Ukubhobozwa kwepuleti ngaphambi kokusika, ngoba ukubhoboza kunokuphakama okuthile, ukubhoboza kusebenzisa ukugxila okungalungile, okungaqinisekisa ukuthi ubukhulu bendawo endaweni yokubhoboza buncane kakhulu, ubukhulu bamandla bukhulu kakhulu, futhi ukujula kwe-perforation kujulile. isikhundla, ukugxila okungalungile kuyancishiswa.
Ukusika i-Zero focus
Okusho ukuthi, ukugxila kokusika kuphezu kwendawo yokusebenza.Ngokuvamile, indawo yokusika eseduze nalapho kugxilwe khona ibushelelezi, futhi indawo ephansi esuka ekugxilweni kokusika iba lukhuni kancane kancane.Lesi simo sisetshenziselwa ikakhulukazi ukusikwa kwe-laser okuqhubekayo kwamapuleti amancane nama-laser we-pulse for high-wavelength power vaporization ukusika izendlalelo ze-foil yensimbi.
