Ingabe Ikhona Indlela Yokugwema I-Burr Lapho Usebenzisa Imishini Yokusika I-Laser?
Impendulo ithi yebo. Enqubweni yokusika insimbi yeshidi, ukulungiselelwa kwepharamitha, ukuhlanzeka kwegesi nokucindezela komoya komshini wokusika we-fiber laser kuzothinta ikhwalithi yokucubungula. Idinga ukusethwa ngokunengqondo ngokuya ngezinto zokucubungula ukuze kuzuzwe umphumela ongcono kakhulu.
Ama-Burrs empeleni ayizinhlayiya zezinsalela ezeqile phezu kwezinto zensimbi. Lapho i-umshini wokusika wensimbi we-lasericubungula i-workpiece, i-laser beam i-irradiate ebusweni be-workpiece, futhi amandla akhiqiziwe ashisa ingaphezulu le-workpiece ukuze kuzuzwe inhloso yokusika. Lapho usika, igesi elisizayo lisetshenziselwa ukuqhuma ngokushesha i-slag endaweni yensimbi, ukuze isigaba sokusika sibushelelezi futhi singabi nama-burrs. Amagesi asizayo ahlukene asetshenziselwa ukusika izinto ezahlukene. Uma igesi ingahlanzekile noma ukucindezela akwanele ukuze kubangele ukugeleza okuncane, i-slag ngeke iqhume ngokuhlanzekile futhi izokwakhiwa ama-burrs.
Uma i-workpiece inama-burrs, ingabhekwa kulezi zici ezilandelayo:
1. Kungakhathaliseki ukuthi ukuhlanzeka kwegesi yokusika akwanele, uma kungenele, buyisela igesi elisizayo lokusika eliphezulu.
2. Ukuthi indawo yokugxila kwe-laser ilungile yini, udinga ukwenza ukuhlolwa kwendawo yokugxila, futhi uyilungise ngokuya ngokusuka kokugxilile.
2.1 Uma indawo okugxilwe kuyo isithuthuke kakhulu, lokhu kuzokhuphula ukushisa okumuncwe indawo engezansi ye-workpiece ezosikwa. Lapho isivinini sokusika kanye nomfutho womoya osizayo kuhlala njalo, izinto ezisikwayo kanye nezinto ezincibilikisiwe eduze kwesikwele kuzoba uketshezi endaweni engezansi. Izinto ezigelezayo futhi ezincibilikisiwe ngemuva kokupholisa zizonamathela endaweni engezansi yendawo yokusebenza ngendlela eyindilinga.
2.2 Uma isikhundla sihlehla. Ukushisa okumuncwa indawo ephansi yokugcina yezinto ezisikiwe kuncishisiwe, ukuze izinto eziku-slit zingakwazi ukuncibilika ngokuphelele, futhi ezinye izinsalela ezibukhali nezifushane zizonamathela endaweni ephansi yebhodi.
3. Uma amandla okukhipha i-laser anele, hlola ukuthi i-laser isebenza ngokujwayelekile yini. Uma kujwayelekile, bheka ukuthi ingabe inani lokukhiphayo lenkinobho yokulawula i-laser lilungile futhi ulungise ngokufanele. Uma amandla amakhulu kakhulu noma amancane kakhulu, isigaba esihle sokusika asikwazi ukutholakala.
4. Ijubane lokusika lomshini wokusika we-laser lihamba kancane noma lishesha kakhulu noma liphuza kakhulu ukuthinta umphumela wokusika.
4.1 Umthelela wesivinini sokuphakela nge-laser esisheshayo kwikhwalithi yokusika:
Kungase kubangele ukungakwazi ukusika kanye nezinhlansi.
Ezinye izindawo zinganqanyulwa, kodwa ezinye izindawo azikwazi ukunqanyulwa.
Ibangela ukuthi sonke isigaba sokusika sibe mkhulu, kodwa awekho amabala ancibilikayo akhiqizwayo.
Ijubane lokuphakelayo lokusika lishesha kakhulu, okwenza ishidi lingakwazi ukunqunywa ngesikhathi, isigaba sokusika sibonisa umgwaqo we-oblique streak, futhi amabala ancibilikayo akhiqizwa engxenyeni engezansi.
4.2 Umthelela wesivinini sokuphakelwa kwe-laser esinensa kakhulu kwikhwalithi yokusika:
Yenza ukuthi ishidi elisikiwe lincibilike kakhulu, futhi ingxenye enqunyiwe ilukhuni.
I-seam yokusika izokwandisa ngokufanele, okwenza yonke indawo incibilike emagumbini amancane ayindilinga noma abukhali, futhi umphumela wokusika ofanele awukwazi ukutholakala. Ukusebenza kahle kokusika kuthinta amandla okukhiqiza.
4.3 Ungasikhetha kanjani isivinini esifanelekile sokusika?
Kusukela ezinhlansini zokusika, ijubane lejubane lokuphakela lingahlulelwa: Ngokuvamile, izinhlansi zokusika zisakazeka ukusuka phezulu kuye phansi. Uma izinhlansi zithambekele, isivinini sokuphakela siyashesha kakhulu;
Uma izinhlansi zingasakazeki futhi zizincane, futhi zifingqiwe ndawonye, kusho ukuthi isivinini sokuphakela sihamba kancane kakhulu. Lungisa isivinini sokusika ngokufanele, indawo yokusika ibonisa umugqa ozinzile, futhi akukho sici esincibilikayo engxenyeni engezansi.
5. Umfutho womoya
Enqubweni yokusika i-laser, umfutho womoya osizayo ungasusa i-slag ngesikhathi sokusika futhi upholise indawo yokusika ethinteke ukushisa. Amagesi asizayo ahlanganisa umoya-mpilo, umoya ocindezelweyo, i-nitrogen, namagesi angenayo. Kwezinye izinto ezisansimbi nezingezona ezensimbi, igesi ye-inert noma umoya ocindezelwe ngokuvamile uyasetshenziswa, ongavimbela into ekushiseni. Njengokusika kwe-aluminium alloy materials. Ezintweni eziningi zensimbi, igesi esebenzayo (njenge-oxygen) isetshenziswa, ngoba i-oksijini ingakwazi ukufaka i-oxidize indawo yensimbi futhi ithuthukise ukusebenza kahle kokusika.
Uma umfutho womoya osizayo uphakeme kakhulu, ama-edad currents avela ebusweni bezinto ezibonakalayo, okwenza buthaka ikhono lokususa izinto ezincibilikisiwe, okubangela ukuthi i-slit ibe banzi futhi indawo yokusika ibe lukhuni;
Uma umfutho womoya uphansi kakhulu, izinto ezincibilikisiwe azikwazi ukushaywa ngokuphelele, futhi indawo ephansi yezinto ezibonakalayo izonamathela ku-slag. Ngakho-ke, umfutho wegesi osizayo kufanele ulungiswe ngesikhathi sokusika ukuze uthole ikhwalithi engcono kakhulu yokusika.
6. Isikhathi eside sokusebenza kwethuluzi lomshini kubangela ukuthi umshini ungahlaliseki, futhi udinga ukuvalwa bese uqalwa kabusha ukuze uvumele umshini ukuba uphumule.
Ngokulungisa izilungiselelo ezingenhla, ngikholwa ukuthi ungathola kalula umphumela owanelisayo wokusika i-laser.
