Imingcele okufanele uyazi lapho usebenzisa umshini wokusika we-fiber laser
Ukusetshenziswa komshini wokusika we-fiber laser abangani bonke bayazi ukuthi umphumela wokusika we-laser usizwa ingcindezi, amandla e-laser, isivinini sokusika, isikhundla sokugxila kanye nemingcele yokusika.Ukulawula imingcele ngokunembile ukuze kuqinisekiswe ikhwalithi yokusika.Ngakho-ke eminye imingcele okufanele uyazi lapho usebenzisa umshini wokusika we-fiber laser.
[ Umthelela wokucindezela okusizayo ]
Imishini ye-laser, indawo ethintekile ekushiseni ingaqhumisa ukusikwa kwegesi kokupholisa nokusika kwe-slag.Amagesi asizayo ahlanganisa umoya-mpilo, umoya ocindezelweyo, i-nitrogen namagesi angasebenzi.Kwezinye izinto zensimbi nezingezona ezensimbi, ukusetshenziswa okuvamile kwegesi ye-inert noma umoya ocindezelwe kungavimbela ukusha kwezinto.Lena ipharamitha eyodwa eyinhloko okufanele uyazi sebenzisa umshini wokusika we-fiber laser.
Isibonelo, ukusika kwe-aluminium alloy material.Ukusetshenziswa kwegesi esebenzayo (njenge-oxygen) ezintweni eziningi zensimbi kungenxa yokuthi i-oksijini ingakwazi ukufaka i-oxidize indawo yensimbi futhi ithuthukise ukusebenza kahle kokusika.Lapho umfutho womoya osizayo uphezulu kakhulu.I-eddy current ebusweni bento esebenzayo yenza buthaka ikhono lokususa into encibilikisiwe, okuholela ekudaleni okubanzi nendawo yokusika emahhadlahhadla.Lapho umfutho womoya uphansi kakhulu, awukwazi ukuphephula ngokuphelele ukuncibilika.
Futhi ubuso obuphansi bezinto ezibonakalayo buzonamathela ku-slag.Ngakho-ke, umfutho wegesi osizayo kufanele ulungise ukuze uthole ikhwalithi engcono kakhulu yokusika.
[ Umthelela wamandla we-laser ]
Ubukhulu bamandla we-laser bunomthelela omkhulu esivinini sokusika, ububanzi be-slit, ukujiya kokusika kanye nekhwalithi yokusika.Ubukhulu bamandla adingekayo buncike ezicini zezinto ezibonakalayo kanye nendlela yokusika.Isibonelo, izinto ezinokusebenza kahle kwe-thermal, indawo ephezulu yokuncibilika kanye nokubonakala okuphezulu endaweni yokusika kudinga amandla amakhulu e-laser.Ngokuvamile, ngaphansi kwezinye izimo, kukhona amandla laser anekhwalithi engcono kakhulu yokusika ekusikeni kwe-laser.
Ukunciphisa noma ukwandisa amandla, kuzodala i-slagging noma ukushisa ngokweqile, okuzoholela ekwehleni kwekhwalithi yokucubungula.Lena ipharamitha eyodwa eyinhloko okufanele uyazi sebenzisa umshini wokusika we-fiber laser
Ngaphezu kwalokho, ngokwanda kwe-voltage yokukhipha, ukushuba kwe-laser kuzokhuphuka ngoba amandla okufakwayo aphezulu ayanda.Ngakho ububanzi bebala buyanda, ububanzi be-slit buyanda.Ngokukhula kobubanzi be-pulse, amandla ajwayelekile we-laser azokhula.Fibre laser cutting ububanzi ukwanda.Ngokuvamile, ngokwanda kwe-pulse frequency, i-cutting joint izoba banzi.Uma i-frequency idlula inani elithile, ububanzi be-kerf buzokwehla.
[ Umthelela wejubane lokusika ]
Enqubweni yokusika i-laser, isivinini sokusika sinethonya elikhulu kukhwalithi yezinto zokusika.Ijubane lokusika endaweni ekahle lizokwenza indawo yokusika ithathe umugqa ozinzile, futhi akukho slag ezovela phansi kwezinto.Lapho umfutho wegesi osizayo namandla e-laser, isivinini sokusika nobubanzi bokusika kukhombisa ubudlelwano obuphambene obungaqondile, lapho ijubane lokusika lihamba kancane, amandla e-laser ukwandisa isikhathi sesenzo ekusikeni umphetho, okuholela ekwandeni kwe-kerf ububanzi, lapho ijubane kancane kakhulu, isenzo se-laser beam long workpiece ekusikeni nasekunciphiseni umehluko kuzoba mkhulu, ikhwalithi yokusika nokusebenza kahle kokukhiqiza kuzoncipha kakhulu.Lena ipharamitha eyodwa eyinhloko okufanele uyazi sebenzisa umshini wokusika we-fiber laser
Ngokukhula kwejubane lokusika, isikhathi sesenzo se-laser beam ku-workpiece siba sifushane.Okwenza ukusabalalisa okushisayo kanye nomphumela wokushisa wokushisa ube mncane.Futhi ububanzi be-slit buyancipha.Lapho ijubane lishesha kakhulu, impahla yokusebenza izonqamula ngenxa yokuntuleka kokusika ukushisa okokufaka kubonakala kunqamula isimo.Lesi simo asinqunywa ngokuphelele.Futhi impahla encibilikayo ayikwazi ukushaywa ngesikhathi, lezi zizoncibilikisa i-slit welding.
[ Umthelela wendawo yokugxila ]
Indawo okugxilwe kuyo yibanga ukusuka ekugxilweni kwe-laser kuya endaweni yokusebenza, okuthinta ngokuqondile ubulukhuni besigaba.Umthambeka nobubanzi bomsinsi kanye nesimo sokunamathela kwezinsalela ezincibilikisiwe.Uma isikhundla sokugxila sisekude kakhulu, kuzoba isiphetho esiphansi se-calories yokusika i-workpiece anda.
Ukusika isivinini kanye nengcindezi eyisizayo ezimweni ezithile.Kuzokwenza ukuthi impahla isike futhi isike eduze kwezinto ezincibilikisiwe wuketshezi olugeleza endaweni engezansi.Ngemuva kokupholisa izinto ezincibilikisiwe, namathisela i-spherical endaweni engezansi ye-workpiece.Uma isikhundla sisalele ngemuva, izinto ezizonqunywa ngaphansi kwendawo zingabamba ukushisa kuncipha.Ngakho-ke izinto zokusika ze-seam azikwazi ukuncibilika ngokuphelele endaweni ephansi yamapuleti azonamathela kwezinye izinsalela ezibukhali nezimfushane.Lena ipharamitha eyodwa eyinhloko okufanele uyazi sebenzisa umshini wokusika we-fiber laser
Ngokuvamile, indawo okugxilwe kuyo kufanele ibe phezu kwendawo yokusebenza noma ibe ngaphansi kancane.Kodwa izidingo zezinto ezibonakalayo zihlukile.Lapho usika insimbi ye-carbon, ikhwalithi yokusika ingcono uma ukugxila kuphezu kweshidi.Ngenkathi insimbi engenasici isika, ukugxila kufanele kube cishe u-1/2 wogqinsi lweshidi.
Sawubona bangane, ngiyabonga ngokufunda kwenu.Ngethemba ukuthi lesi sihloko singakusiza.
Uma ufuna ukuthola ulwazi olwengeziwe, wamukelekile ukushiya umyalezo kusizindalwazi sethu, noma ubhalele i-imeyili ku:sale12@ruijielaser.ccUNkosazana Anne.
Siyabonga ngesikhathi sakho esiyigugu
