Indlela yokuxazulula i-burr ekhiqizwa yinsimbi yokusika nge-laser

I-burr ekhiqizwa lapho insimbi yokusika nge-laser iyinkinga evamile yenqubo, okuvame ukukhombisa ukuthi inqubo yokusika ayilungile. Ukuze kuxazululwe le nkinga ngokuhlelekile, kubalulekile ukuhlola nokulungisa kusuka ezilinganisweni eziningi njengemishini, izinto zokwakha, amapharamitha enqubo kanye namagesi asizayo.

Isiqondiso sokwenza ngcono okuyisisekelo kanye nezinyathelo ezithile

1. Lungiselela amapharamitha enqubo (yensimbi yekhabhoni nezinye izinto)

• Amandla e-laser: amandla anganele ingenye yezimbangela eziyinhloko zama-burrs. Ukwandisa amandla ngendlela efanele kungaqinisekisa ukuthi insimbi incibilike ngokuphelele. Kodwa-ke, kufanele kuqashelwe ukuthi amandla aphezulu kakhulu angabangela ukuthi ipuleti lishise noma lilengise i-slag.
• Isivinini sokusika: Isivinini sishesha kakhulu, okokufaka amandla e-laser akwanele, izinto azincibiliki ngokuphelele, futhi zizoshaywa umoya zibe yizimbobo; uma isivinini sihamba kancane kakhulu, ukusha kuzoba kubi kakhulu futhi i-slag izonamathela. Lungisa isivinini esingcono kakhulu esifanelana namandla kanye nobukhulu bepuleti. Ngokuvamile ungahlola amapharamitha kuqala. Indawo yokugxila: Ukugxila okungalungile kuzoholela ekunganele kwamandla. Hlola ukugxila ukuze uthole indawo efanele kakhulu yobukhulu bepuleti yamanje (ngokuvamile lapho usika insimbi yekhabhoni, ukugxila kuba ngaphezulu kwepuleti noma ngaphansi kancane).

2. Qinisekisa ukuthi igesi elisizayo lisesimweni esihle kakhulu (isici esibaluleke kakhulu)

• Uhlobo lwegesi kanye nobumsulwa:
• Ukusika insimbi yekhabhoni: I-oxygen emsulwa kakhulu (≥ 99.95%) kumele isetshenziswe. I-oxygen ibamba iqhaza ekusabeleni kwe-exothermic, isiza ekushiseni nasekuphephuleni i-slag. Ukungahlanzeki okwanele kuzothinta kakhulu ikhwalithi yokusika kanye nesendlalelo se-oxide sesigaba.

Ukusika insimbi engagqwali kanye ne-aluminium: kufanele kusetshenziswe i-nitrogen ehlanzekile kakhulu (≥ 99.99%) noma i-argon. Sebenzisa igesi enomfutho ophezulu ukuze uphephule insimbi encibilikisiwe ukuze ufinyelele ukusika okungena-oxidation. Igesi engcolile izobangela i-slag phansi.

• Umfutho wegesi:
• Ukusika insimbi yekhabhoni (ngomoya-mpilo): ingcindezi akufanele ibe phezulu kakhulu (ngokuvamile i-0.8-2bar). Ingcindezi enkulu izopholisa ukusikwa, kodwa yehlise ukusebenza kahle kokusabela kokusha, ukwakheka kwama-burrs.
• Ukusika insimbi engagqwali/i-aluminium (ene-nitrogen): Ukucindezela kumele kube phezulu ngokwanele (ngokuvamile amabha ayi-10-20, kuye ngokuthi ipuleti libanzi kangakanani). Ukucindezela okunganele kuyimbangela evame kakhulu yokwehluleka kokusika okungena-burr, futhi insimbi encibilikisiwe ayikwazi ukupheshulwa ngokuphelele.
• Isimo se-Nozzle:
• Hlola ukuqinisekisa ukuthi umlomo awuwonakele noma awuvinjiwe ukuchitheka. Umlomo ogugile ungabangela ukuphazamiseka komoya.
• Hlola ukuthi ububanzi bembobo ye-nozzle buyahambisana yini nobukhulu bepuleti kanye nomfutho wegesi. Amapuleti aqinile ngokuvamile adinga ama-nozzle amakhulu e-orifice.
• Linganisa ukugxila kwe-nozzle kanye nekhanda le-laser. Ukuphambuka kokugxila kuzokwenza igesi iqhume futhi ikhiqize ama-burrs ohlangothini olulodwa.

3. Hlola futhi ulondoloze isimo semishini

• Ukuhlanzwa kwelensi yokubona: isibuko sokuvikela, ukugxila ekungcoleni kwesibuko kuzonciphisa kakhulu amandla e-laser kanye nekhwalithi yemisebe. Hlola njalo futhi uhlanze noma ushintshe amalensi.
• Ikhwalithi yomugqa: ukulinganiswa komugqa okuvamile ukuqinisekisa ukuthi indlela yokukhanya ilungile nokuthi ukugxila kujikelezile.
• Ukuqina kwemishini: Hlola ukuthi ngabe uhlelo lwesitimela somhlahlandlela wamathuluzi omshini kanye nohlelo lokudlulisela luzinzile yini, nokuthi ama-burrs angajwayelekile azokhiqizwa uma kushukunyiswa ngesivinini esikhulu.

4. Gxila ezintweni ezibonakalayo

• Ubuso beshidi: Qinisekisa ukuthi ubuso beshidi abunawo umgqwala omkhulu, upende noma uqweqwe, okuzothinta ukumuncwa kwe-laser kanye nokuqina kokusika.
• Ukwakheka kwezinto kanye nekhwalithi: ikhwalithi ephansi noma ukwakheka kwe-alloy engalingani kwepuleti nakho kungaholela ekushintsheni komphumela wokusika.

Ukukhathazeka Okukhethekile Ngezinkinga zeBurr Ezintweni Ezihlukahlukene

• Ipuleti lensimbi yekhabhoni (ukusika umoya-mpilo): i-burr engezansi ikakhulukazi i-iron oxide slag eqinile futhi ebuthakathaka. Ngokuyinhloko isuka ekuhlanzekeni komoya-mpilo, isikhundla sokugxila, kanye nokuhambisana kwesivinini samandla.
• Ipuleti le-aluminiyamu lensimbi engagqwali (ukusika i-nitrogen): ama-burrs angezansi athambile kakhulu futhi ande angapheshulwanga ngensimbi encibilikisiwe. Umsebenzi wokuqala ukuhlola ukuthi ingcindezi ye-nitrogen iphakeme ngokwanele, ukuthi igesi ihlanzekile yini, nokuthi i-nozzle iyafaneleka yini.

Izincomo zenqubo yokuxazulula okuhlelekile

1. Qopha futhi ukopishe:qopha uhlobo lwepuleti le-burr lamanje, ukujiya, kanye nazo zonke izinhlaka zenqubo (amandla, isivinini, umfutho womoya, ukugxila, uhlobo lwe-nozzle) ngokuningiliziwe.

2. Ukulungiswa okuguquguqukayo okukodwa:lungisa ipharamitha eyodwa ngesikhathi (kunconywa ukuthi uqale ngomfutho wegesi kanye nendawo yokugxila kuqala) ukuze kuqhathaniswe ukusika kwesilingo.

3. Kusukela ekuxazululeni izinkinga okulula kuya kokuyinkimbinkimbi:

• Isinyathelo 1: Hlola futhi uhlanze umlomo nelensi.
• Isinyathelo sesi-2: Hlola ubumsulwa begesi kanye nokucindezela kwayo.
• Isinyathelo 3: Lungiselela indawo yokugxila.
• Isinyathelo 4: Lungisa ukufana kwamandla nesivinini.
• Isinyathelo 5: lungisa indlela yokukhanya kanye nokugxila kwedivayisi.

4. Misa umtapo wolwazi ojwayelekile wepharamitha:uma sekutholakale amapharamitha amahle kakhulu amapuleti ezinhlobo ezahlukene, ubukhulu kanye nezinto zokwakha, azoqoshwa ukuze akhe imiyalelo yokusebenza ejwayelekile.

Isifinyezo:Ingqikithi yokuxazulula inkinga yama-laser cutting burrs "ukuqinisekisa ukuthi amandla anele afakwa, futhi ubambisane nesiqondiso esizinzile, esimsulwa, nesifanele sokugeleza komoya ukuze kuqhume ukuncibilika ngesikhathi". Kuyinkinga ehlelekile edinga ukuthi opharetha abe nesineke futhi aphenye kancane kancane futhi enze ngcono ngezindlela zesayensi. Uma zonke izinyathelo ezingenhla zihlolwa futhi inkinga iqhubeka ngemva kokulungiswa, udinga ukuxhumana nomkhiqizi wemishini ukuze uhlole ukuthi imodi yamandla noma ye-beam yokukhipha i-laser ishintshile yini.
