Ingabe Ikhona Indlela Yokugwema I-Burr Uma Usebenzisa Imishini Yokusika Nge-Laser?
Impendulo inguyebo. Enkambisweni yokucubungula ukusika insimbi eshidi, ukusethwa kwepharamitha, ubumsulwa begesi kanye nomfutho womoya womshini wokusika i-fiber laser kuzothinta ikhwalithi yokucubungula. Kudingeka kubekwe ngokufanele ngokwezinto zokucubungula ukuze kufezwe umphumela omuhle kakhulu.
Ama-burrs empeleni ayizinhlayiya eziningi kakhulu ezisele phezu kwezinto zensimbi. Umaumshini wokusika we-laser wensimbiicubungula ingxenye yokusebenza, umsebe we-laser ukhanyisa indawo yokusebenza, futhi amandla akhiqizwayo aphefumula indawo yokusebenza ukuze kufezwe injongo yokusika. Lapho kunqunywa, kusetshenziswa igesi elisizayo ukuqeda ngokushesha i-slag ebusweni bensimbi, ukuze ingxenye yokusika ibe bushelelezi futhi ingabi nama-burrs. Amagesi asizayo ahlukene asetshenziswa ukusika izinto ezahlukene. Uma igesi ingahlanzekile noma ingcindezi inganele ukubangela ukugeleza okuncane, i-slag ngeke ivuthelwe kahle futhi ama-burrs azokwakhiwa.
Uma umsebenzi unama-burrs, ungahlolwa kusukela kulezi zici ezilandelayo:
1. Ukuthi ubumsulwa begesi yokusika akwanele yini, uma bunganele, shintsha igesi yokusika esezingeni eliphezulu.
2. Kungakhathaliseki ukuthi indawo yokugxila nge-laser ilungile, udinga ukwenza ukuhlolwa kwendawo yokugxila, bese uyilungisa ngokwesilinganiso sokugxila.
2.1 Uma indawo yokugxila ithuthuke kakhulu, lokhu kuzokwandisa ukushisa okumuncwa yisiphetho esingezansi sento yokusebenza okufanele isikwe. Uma isivinini sokusika kanye nomfutho womoya osizayo kuhlale njalo, into esikwayo kanye nezinto ezincibilikisiwe eduze kwesikhala kuzoba uketshezi endaweni engezansi. Izinto ezigeleza futhi zincibilikiswe ngemva kokupholisa zizonamathela endaweni engezansi yento yokusebenza ngesimo esiyindilinga.
2.2 Uma indawo ibambezeleka. Ukushisa okumuncwa yisiphetho esingezansi sento esinqunyiwe kuyancishiswa, ukuze izinto ezisesikhaleni zingancibiliki ngokuphelele, futhi ezinye izinsalela ezibukhali nezimfushane zizonamathela endaweni engezansi yebhodi.
3. Uma amandla okukhipha e-laser anele, hlola ukuthi i-laser isebenza kahle yini. Uma kujwayelekile, bheka ukuthi inani lokukhipha lenkinobho yokulawula i-laser lilungile yini bese ulungisa ngokufanele. Uma amandla makhulu kakhulu noma mancane kakhulu, ingxenye enhle yokusika ayikwazi ukutholakala.
4. Ijubane lokusika lomshini wokusika nge-laser lihamba kancane kakhulu noma lishesha kakhulu noma lihamba kancane kakhulu ukuthinta umphumela wokusika.
4.1 Umphumela wesivinini sokuphakelwa kwe-laser esisheshayo kakhulu kwikhwalithi yokusika:
Kungabangela ukungakwazi ukusika kanye nezinhlansi.
Ezinye izindawo zinganqunywa, kodwa ezinye izindawo azikwazi ukunqunywa.
Kubangela ukuthi yonke ingxenye yokusika ibe nkulu, kodwa akukho mabala ancibilikayo avelayo.
Isivinini sokuphakelwa kokusika sishesha kakhulu, okwenza ishidi lingakwazi ukunqunywa ngesikhathi, ingxenye yokusika ikhombisa umgwaqo oqondile, futhi amabala ancibilikayo akhiqizwa engxenyeni engezansi.
4.2 Umphumela wesivinini sokuphakelwa kwe-laser esihamba kancane kakhulu kwikhwalithi yokusika:
Yenza ishidi lokusika lincibilike kakhulu, futhi ingxenye yokusika ibe mahhadlahhadla.
Umthungo wokusika uzokhula ngokufanele, okwenza yonke indawo incibilike emakhoneni amancane ayindilinga noma abukhali, futhi umphumela wokusika ofanele awukwazi ukutholakala. Ukusebenza kahle kokusika okuphansi kuthinta amandla okukhiqiza.
4.3 Ungayikhetha kanjani isivinini esifanele sokusika?
Kusukela ezinhlansini zokusika, ijubane lejubane lokuphakela lingahlulelwa: Ngokuvamile, izinhlansi zokusika zisakazeka kusukela phezulu kuya phansi. Uma izinhlansi zithambekele, ijubane lokuphakela lishesha kakhulu;
Uma izinhlansi zingasabalali futhi zincane, futhi zihlangene ndawonye, kusho ukuthi isivinini sokudla sihamba kancane kakhulu. Lungisa isivinini sokusika ngokufanele, indawo yokusika ikhombisa umugqa ozinzile, futhi akukho daba lokuncibilika engxenyeni engezansi.
5. Umfutho womoya
Enqubweni yokusika nge-laser, umfutho womoya osizayo ungasusa i-slag ngesikhathi sokusika futhi upholise indawo ethintekile ekushiseni kokusika. Amagesi asizayo afaka umoya-mpilo, umoya ocindezelwe, i-nitrogen, kanye namagesi angasebenzi. Kwezinye izinto zensimbi nezingezona ezensimbi, igesi engasebenzi noma umoya ocindezelwe ngokuvamile kusetshenziswa, okungavimbela izinto ukuthi zingashi. Njengokusika izinto ze-aluminium alloy. Ezintweni eziningi zensimbi, kusetshenziswa igesi esebenzayo (njenge-oxygen), ngoba umoya-mpilo ungangcolisa ubuso bensimbi futhi uthuthukise ukusebenza kahle kokusika.
Uma umfutho womoya osizayo uphezulu kakhulu, kuvela imisinga ye-eddy ebusweni bento, okwenza buthaka ikhono lokususa into encibilikisiwe, okwenza ukuthi umngxuma ube banzi futhi indawo yokusika ibe magebhugebhu;
Uma umfutho womoya uphansi kakhulu, izinto ezincibilikisiwe azikwazi ukupheshulwa ngokuphelele, futhi ubuso obungaphansi bezinto buzonamathela ku-slag. Ngakho-ke, umfutho wegesi osizayo kufanele ulungiswe ngesikhathi sokusika ukuze kutholakale ikhwalithi yokusika engcono kakhulu.
6. Ukusebenza isikhathi eside kwethuluzi lomshini kubangela ukuthi umshini ungazinzile, futhi udinga ukuvalwa bese uqala kabusha ukuze umshini uphumule.
Ngokulungisa izilungiselelo ezingenhla, ngikholwa ukuthi ungathola kalula umphumela wokusika nge-laser owanelisayo.
