Ngaba ikho indlela yokuphepha iBurr xa usebenzisa oomatshini bokusika iLaser?
Impendulo ithi ewe. Kwinkqubo yokucubungula isinyithi, useto lweparameter, ubunyulu begesi kunye noxinzelelo lomoya lomatshini wokusika i-fiber laser kuya kuchaphazela umgangatho wokucubungula. Kufuneka ibekwe ngokufanelekileyo ngokwezixhobo zokucubungula ukuze kufezekiswe isiphumo esingcono.
IiBurrs ngokwenene ziintsalela ezininzi ezikwindawo yesinyithi.umatshini wokusika i-laser yesinyithiicubungula isiqwenga somsebenzi, umqadi welaser ukhanyisa umphezulu wesiqwenga somsebenzi, kwaye amandla avelisiweyo aphembelela umphezulu wesiqwenga somsebenzi ukuze kufezekiswe injongo yokusikwa. Xa kusikwa, kusetyenziswa igesi encedisayo ukuvuthuza ngokukhawuleza i-slag kumphezulu wesinyithi, ukuze icandelo lokusikwa libe bushelelezi kwaye lingabi nama-burrs. Iigesi ezincedisayo ezahlukeneyo zisetyenziselwa ukusika izinto ezahlukeneyo. Ukuba igesi ayicocekanga okanye uxinzelelo alwanelanga ukubangela ukuhamba okuncinci, i-slag ayizukuvuthelwa ngokucocekileyo kwaye ama-burrs aya kwenziwa.
Ukuba i-workpiece inee-burrs, ingajongwa kwezi zinto zilandelayo:
1. Nokuba ubunyulu begesi yokusika awanelanga, ukuba awanelanga, tshintsha igesi yokusika esemgangathweni ophezulu.
2. Nokuba indawo yokugxila kwelaser ichanekile, kufuneka wenze uvavanyo lwendawo yokugxila, kwaye uyilungise ngokwe-offset ye-focus.
2.1 Ukuba indawo yokugxila ihambele phambili kakhulu, oku kuya kwandisa ubushushu obufunxwa sisiphelo esisezantsi sesixhobo sokusebenza esiza kunqunyulwa. Xa isantya sokusika kunye noxinzelelo lomoya oluncedisayo zizinzile, izinto ezisikiweyo kunye nezinto ezinyibilikisiweyo kufutshane nomngxuma ziya kuba lulwelo kumphezulu ongezantsi. Izinto ezigeleza kwaye zinyibilike emva kokupholisa ziya kunamathela kumphezulu ongezantsi wesixhobo sokusebenza ngendlela engqukuva.
2.2 Ukuba indawo isemva. Ubushushu obufunxwa ngumphezulu osezantsi wento enqunyulweyo buyancipha, ukuze izinto ezikwisithuba zinganyibiliki ngokupheleleyo, kwaye ezinye iintsalela ezibukhali nezimfutshane ziya kunamathela kumphezulu ongezantsi webhodi.
3. Ukuba amandla okukhupha elaser anele, jonga ukuba ilaser isebenza ngokuqhelekileyo na. Ukuba iqhelekile, jonga ukuba ixabiso lokukhupha iqhosha lokulawula ilaser lichanekile na uze ulungise ngokufanelekileyo. Ukuba amandla makhulu kakhulu okanye mancinci kakhulu, icandelo elihle lokusika alinakufumaneka.
4. Isantya sokusika somatshini wokusika nge-laser sicotha kakhulu okanye sikhawuleza kakhulu okanye sicotha kakhulu ukuba singachaphazela isiphumo sokusika.
4.1 Isiphumo sesantya sokusika nge-laser esikhawulezayo kakhulu kumgangatho wokusika:
Ingabangela ukungakwazi ukusika kunye neentlantsi.
Ezinye iindawo zinokunqunyulwa, kodwa ezinye iindawo azinakunqunyulwa.
Ibangela ukuba lonke icandelo lokusika libe likhulu, kodwa akukho mabala anyibilikayo avelayo.
Isantya sokutya esinqunyiweyo sikhawuleza kakhulu, nto leyo ebangela ukuba iphepha lingakwazi ukunqunyulwa ngexesha, icandelo lokusika libonisa indlela ethe tyaba, kwaye amabala anyibilikayo avela kwisiqingatha esisezantsi.
4.2 Isiphumo sesantya sokutya esicothayo kakhulu sokusika nge-laser kumgangatho wokusika:
Yenza ukuba iphepha elisikiweyo linyibilike kakhulu, kwaye icandelo elisikiweyo libe rhabaxa.
Umthungo wokusika uya kwanda ngokufanelekileyo, nto leyo ebangela ukuba yonke indawo inyibilike kwiikona ezincinci ezingqukuva okanye ezibukhali, kwaye isiphumo sokusika esifanelekileyo asinakufunyanwa. Ukusebenza kakuhle kokusika kuchaphazela amandla emveliso.
4.3 Ungayikhetha njani isantya esifanelekileyo sokusika?
Ukusuka kwiintlantsi zokusika, isantya sesantya sokutya sinokugwetywa: Ngokubanzi, iintlantsi zokusika zisasazeka ukusuka phezulu ukuya ezantsi. Ukuba iintlantsi zithe tye, isantya sokutya sikhawuleza kakhulu;
Ukuba iintlantsi azisasazeki kwaye zincinci, kwaye zidibene, oko kuthetha ukuba isantya sokutya sicotha kakhulu. Lungisa isantya sokusika ngokufanelekileyo, umphezulu wokusika ubonisa umgca ozinzileyo, kwaye akukho daka lokunyibilika kwisiqingatha esisezantsi.
5. Uxinzelelo lomoya
Kwinkqubo yokusika nge-laser, uxinzelelo lomoya oluncedisayo lunokukhupha i-slag ngexesha lokusika kwaye lupholise indawo echaphazelekileyo bubushushu bokusika. Iigesi ezincedisayo ziquka ioksijini, umoya ocinezelweyo, i-nitrogen, kunye neegesi ezingasebenziyo. Kwezinye izinto zesinyithi nezingezizo zesinyithi, igesi engasebenziyo okanye umoya ocinezelweyo ngokubanzi kusetyenziswa, nto leyo enokuthintela ukutsha kwezinto. Njengokusika izinto ze-aluminium alloy. Kwiimpahla ezininzi zesinyithi, kusetyenziswa igesi esebenzayo (efana neoksijini), kuba ioksijini inokunyibilikisa umphezulu wesinyithi kwaye iphucule ukusebenza kakuhle kokusika.
Xa uxinzelelo lomoya oluncedisayo luphezulu kakhulu, kuvela imisinga ye-eddy kumphezulu wento, nto leyo ebangela ukuba amandla okususa izinto ezinyibilikisiweyo angabi maninzi, nto leyo ebangela ukuba umngxuma ube banzi kwaye umphezulu wokusika ube rhabaxa;
Xa uxinzelelo lomoya luphantsi kakhulu, izinto ezinyibilikisiweyo azinakuphetshethwa ngokupheleleyo, kwaye umphezulu ongezantsi wezinto uya kunamathela kwi-slag. Ke ngoko, uxinzelelo lwegesi oluncedisayo kufuneka lulungiswe ngexesha lokusika ukuze kufunyanwe umgangatho wokusika ongcono.
6. Ukusebenza ixesha elide kwesixhobo somatshini kubangela ukuba umatshini ungahlali uzinzile, kwaye kufuneka ucinywe kwaye uqalwe kwakhona ukuvumela umatshini ukuba uphumle.
Ngokulungisa useto olungentla, ndikholelwa ukuba ungafumana isiphumo sokusika nge-laser esanelisayo ngokulula.
