Ngaba ikho indlela yokuNqanda iBurr xa usebenzisa oomatshini bokusika iLaser?
Impendulo nguewe. Kwinkqubo yokusika i-sheet metal processing, i-parameter setting, ukucoceka kwegesi kunye noxinzelelo lomoya we-fiber laser cutting machine kuya kuchaphazela umgangatho wokucubungula. Idinga ukusetwa ngokufanelekileyo ngokwemathiriyeli yokucubungula ukufezekisa umphumo ongcono.
IiBurrs ngokwenene ngamasuntswana entsalela engaphezulu kumphezulu wemathiriyeli yesinyithi. Xa umatshini wokusika umatshini we-laser wensimbi usebenza, umqadi we-laser usasaza umphezulu we-workpiece, kwaye amandla avelisiweyo akhupha umphezulu we-workpiece ukuze afezekise injongo yokusika. Xa usika, igesi encedisayo isetyenziselwa ukukhawuleza ukukhupha i-slag kwindawo yesinyithi, ukwenzela ukuba icandelo lokusika lihambe kakuhle kwaye lingabikho burrs. Iigesi ezincedisayo ezahlukeneyo zisetyenziselwa ukusika izinto ezahlukeneyo. Ukuba igesi ayihlambulukanga okanye uxinzelelo alwanelanga ukuba lubangele ukuhamba okuncinci, i-slag ayiyi kubethwa ngokucocekileyo kwaye i-burrs iya kwenziwa.
Ukuba i-workpiece ine-burrs, inokujongwa kule miba ilandelayo:
1. Ingaba ukucoceka kwegesi yokusika akwanele, ukuba ayanele, buyisela i-gas yokuncedisa i-high quality cut cut.
2. Ingaba indawo yokugxilwa kwe-laser ichanekile, kufuneka wenze uvavanyo lokugxila, kwaye ulungelelanise ngokwe-offset yokugxila.
2.1 Ukuba indawo ekugxilwe kuyo iphezulu kakhulu, oku kuya kwandisa ubushushu obufunnwe yisiphelo esisezantsi se-workpiece ukuba sinqunywe. Xa isantya sokusika kunye noxinzelelo lomoya oluncedisayo luhlala luhlala, izinto ezisikwayo kunye nezinto ezinyibilikayo kufuphi ne-slit ziya kuba ngamanzi kwindawo ephantsi. Izinto eziqukuqelayo kwaye zinyibilike emva kokupholisa ziya kubambelela kumphezulu ongaphantsi we-workpiece kwi-spherical shape.
2.2 Ukuba indawo ibambekile. Ubushushu obubanjwe ngumgangatho ophantsi wesiphelo sezinto ezisikiweyo ziyancipha, ukwenzela ukuba izinto ezikwi-slit azikwazi ukunyibilika ngokupheleleyo, kwaye ezinye iintsalela ezibukhali nezifutshane ziya kubambelela kwindawo ephantsi yebhodi.
3. Ukuba amandla okuphuma kwelaser anele, khangela ukuba i-laser isebenza ngokuqhelekileyo. Ukuba yinto eqhelekileyo, jonga ukuba ixabiso lemveliso yeqhosha lokulawula i-laser lichanekile kwaye ulungelelanise ngokufanelekileyo. Ukuba amandla amakhulu kakhulu okanye amancinci, icandelo elihle lokusika alinakufumaneka.
4. Isantya sokusika umatshini wokusika we-laser ucotha kakhulu okanye ukhawuleza okanye ucotha kakhulu ukuchaphazela umphumo wokusika.
4.1 Isiphumo sokukhawuleza kakhulu kwesantya sokusika i-laser kumgangatho wokusika:
Inokubangela ukungakwazi ukusika kunye neentlantsi.
Ezinye iindawo zinokunqunyulwa, kodwa ezinye iindawo azinakunqunyulwa.
Ibangela ukuba lonke icandelo lokusika libe likhulu, kodwa akukho mabala anyibilikayo aveliswayo.
Isantya sokutya sokusika sikhawuleza, sibangela ukuba iphepha lingakwazi ukunqunyulwa ngexesha, icandelo lokusika libonisa indlela ye-oblique streak, kunye ne-melting stains ziveliswa kwisiqingatha esisezantsi.
4.2 Isiphumo sokucotha kakhulu kwesantya sokusika i-laser kumgangatho wokusika:
Yenza ukuba ishidi elisikiweyo lincibilike kakhulu, kwaye icandelo elisikiweyo linzima.
I-seam yokusika iya kwandiswa ngokufanelekileyo, ibangela ukuba yonke indawo inyibilike kwiikona ezincinci ezijikelezileyo okanye ezibukhali, kwaye umphumo ofanelekileyo wokusika awunakufumaneka. Ukusebenza okuphantsi kokusika kuchaphazela amandla okuvelisa.
4.3 Indlela yokukhetha isantya esifanelekileyo sokusika?
Ukususela kwiintlantsi zokusika, isantya sesantya sokutya sinokugwetywa: Ngokuqhelekileyo, iintlantsi zokusika zisasazeka ukusuka phezulu ukuya phezulu. Ukuba iintlantsi zithambekele, isantya sokutya sikhawuleza kakhulu;
Ukuba iintlantsi azisasazeki kwaye zincinci, kwaye zihlanganiswe kunye, oko kuthetha ukuba isantya sokutya sicotha kakhulu. Lungisa isantya sokusika ngokufanelekileyo, indawo yokusika ibonisa umgca ozinzile, kwaye akukho ndawo encibilikayo kwisiqingatha esisezantsi.
5. Uxinzelelo lomoya
Kwinkqubo yokusika i-laser, uxinzelelo lomoya oluncedisayo lunokuvuthela i-slag ngexesha lokusika kunye nokupholisa indawo echaphazelekayo yokushisa. Iigesi ezincedisayo ziquka ioksijini, umoya oxinanisiweyo, initrogen, kunye neegesi ezingenayo. Kwezinye izinto zetsimbi kunye nezingezizo ezentsimbi, igesi engasebenziyo okanye umoya ocinezelweyo isetyenziswa ngokuqhelekileyo, enokuthintela ukutsha kwezinto. Okufana nokusikwa kwezinto ze-aluminium alloy. Ubuninzi bezinto zetsimbi, igesi esebenzayo (efana neoksijini) isetyenzisiweyo, kuba i-oksijini inokuthi i-oxidize i-metal surface kwaye iphucule ukusebenza kakuhle kokusika.
Xa uxinzelelo lomoya oncedisayo luphezulu kakhulu, ama-eddy currents avela ebusweni bezinto eziphathekayo, ezenza buthathaka amandla okususa izinto ezityhidiweyo, ezibangela ukuba i-slit ibe banzi kwaye indawo yokusika ibe yingozi;
Xa uxinzelelo lomoya luphantsi kakhulu, izinto ezityhidiweyo azikwazi ukutshitshiswa ngokupheleleyo, kwaye indawo engaphantsi kwezinto iya kubambelela kwi-slag. Ngoko ke, uxinzelelo lwegesi oluncedisayo kufuneka lutshintshwe ngexesha lokusika ukuze ufumane umgangatho obalaseleyo wokusika.
6. Ixesha elide lokuqhuba isixhobo somatshini libangela ukuba umatshini ungazinzi, kwaye kufuneka uvalwe kwaye uqalise kwakhona ukuvumela umatshini ukuba uphumle.
Ngokulungelelanisa ezi zicwangciso zingentla, ndiyakholelwa ukuba unokufumana lula umphumo owanelisayo wokusika i-laser.
