Indlela yokuxazulula inkinga yama-burrs ekusikeni amapuleti amancane nge-laser

Ukuvela kwama-burrs ekusikeni kwe-laser kwama-plate amancane kuyinkinga evamile kakhulu. Lokhu ngokuvamile akubangelwa yinto eyodwa kodwa kuwumphumela womphumela ohlangene wezinto eziningi ezifana nemishini, amapharamitha, izinto zokwakha, namagesi. Ukuze sixazulule le nkinga ngokuhlelekile, singalandela inqubo yokuxazulula izinkinga kusukela kokulula kuya kokunzima kanye nesofthiwe kuya kwehadiwe. Okulandelayo, sizochaza kabanzi ngemisebenzi ethile kanye nezixazululo zesinyathelo ngasinye ngokuningiliziwe:

Isinyathelo 1: Ukuhlolwa nokulungiswa kwepharamitha eyinhloko (indawo yenkinga evame kakhulu)

1. Indawo yokugxila

• Indawo yokugxila ingenye yemingcele ebaluleke kakhulu ethinta ikhwalithi yokusika. Ukugxila okungalungile kuzoholela ekutheni amandla angagxili, okwenza kube nzima ukususa i-slag ngempumelelo.
• Izimpawu: Kokubili ukugxila okuphezulu kakhulu noma okuphansi kakhulu kuzokwenza ukuthi i-slag inamathele phansi (ama-burrs).

Isixazululo:

• Yenza ukulinganisa ukugxila: Okokuqala, qiniseka ukuthi ukugxila kwemishini yakho kunembile. Sebenzisa i-focus gauge noma umsebenzi wokulinganisa ozenzakalelayo.
• Yenza ukuhlolwa kokugxila: Esiqeshini esilahliwe, sika umugqa oqondile noma indilinga ezindaweni ezahlukene zokugxila (isibonelo, kusukela ku--1mm kuya ku-+1mm, ngesikhawu esingu-0.2mm), bese ubheka ukuthi iyiphi indawo enezimbobo ezincane kakhulu. Kumapuleti amancane, kuvame ukunconywa ukusebenzisa i-negative defocusing (okungukuthi, ukugxila kungaphansi kobuso bepuleti, ebangeni elingaba yi-1/3 kuya ku-1/2 yobukhulu bepuleti), okungakha ukusika okubanzi futhi kube lula ukupheshulwa kwe-slag ngokugeleza kwegesi.

2. Igesi elisizayo

Uhlobo lwegesi kanye nobumsulwa:

• Ukusika insimbi yekhabhoni: Kumelwe usebenzise umoya-mpilo. I-oksijini ibamba iqhaza ekusabeleni kokusha, ihlinzeka ngamandla engeziwe futhi yakhe i-iron oxide enephuzu eliphansi lokuncibilika, epheshulwa kalula ukugeleza kwegesi. Uma kusetshenziswa umoya noma i-nitrogen, kuzokhiqizwa inani elikhulu lama-black slag burrs.
• Ukusika insimbi engagqwali, i-aluminium alloy: Kumelwe usebenzise i-nitrogen emsulwa kakhulu. Indima ye-nitrogen ukuphefumula insimbi encibilikisiwe nokuvimbela i-oxidation. Uma ubumsulwa be-nitrogen bunganele (okushiwo ukuthi bungaphezu kuka-99.9%) noma ingcindezi iphansi kakhulu, ama-burrs azokwakheka phansi kwezinto ngenxa ye-oxidation kanye nokupholisa okunganele.

Umfutho wegesi:

• Ukucindezela okuphansi kakhulu: Ayikwazi ukuqeda ngempumelelo i-slag, okubangela ukuthi ama-burrs anqwabelane phansi.
• Ukucindezela okuphezulu kakhulu: Kumapuleti amancane, ukucindezela okukhulu kungadala ama-vortices lapho kunqunywa, kwenze buthaka umphumela wokuqhuma kwe-slag futhi mhlawumbe kubangele izindawo ezisikiwe eziqinile ngisho namaqhubu ancibilikisiwe okunzima ukuwasusa.

Isixazululo:Bheka amapharamitha anconyiwe avela kumkhiqizi wemishini ngokusekelwe ohlotsheni lwezinto kanye nobukhulu, bese wenza ukulungisa okuhle ngokufanele. Isibonelo, lapho usika insimbi yekhabhoni engu-1mm, ingcindezi ye-oxygen ivame ukuba phakathi kuka-0.8-1.2Bar.

3. Isivinini sokusika kanye namandla e-laser

• Lezi ezimbili zidinga ukufana ngokuphelele.
• Isivinini esisheshayo: Amandla angenele okufakwayo, izinto azincibiliki ngokuphelele futhi azinqunywanga, okushiya ama-burrs aqhubekayo, anamathelayo phansi.
• Isivinini esihamba kancane kakhulu: Ukufakwa kwamandla ngokweqile, okubangela ukuba izinto zincibilike ngokweqile, okuholela endaweni esikiwe kakhulu ngisho nokwakheka kwezigaxa ezincibilikisiwe okunzima ukuzisusa.
• Ukungafani kwamandla: Amandla aphansi kakhulu alingana nesivinini esisheshayo kakhulu, kanti amandla aphezulu kakhulu alingana nesivinini esihamba kancane kakhulu.

Isixazululo:

• Yenza ukuhlolwa kwamapharamitha: Lungisa amanye amapharamitha bese ulungisa isivinini sokusika kanye namandla ukuze uthole inhlanganisela engcono kakhulu "yamandla esivinini". Isimo sokusika esifanele yiphethini efana nembali ehlakazeka phansi ngokulinganayo.

Isinyathelo 2: Ukuhlolwa kwesimo sehadiwe kanye nemishini

Uma ukulungiswa kwamapharamitha kungasebenzi kahle, imishini ngokwayo idinga ukuhlolwa.

1. I-Nozzle

• Ukukhetha i-nozzle: Ukusebenzisa i-nozzle enobubanzi obukhulu kakhulu (njenge-φ2.0 noma ngaphezulu) akuhambisani nokugcwala kokugeleza kwegesi. Kumapuleti amancane, kunconywa ukusebenzisa i-nozzle enobubanzi obuncane (njenge-φ1.0 noma i-φ1.5), engakhiqiza ukugeleza kwegesi okushesha kakhulu futhi ibe nomphumela ongcono wokuqhuma kwe-slag.
• Isimo se-nozzle: Hlola ukuthi kukhona yini ukuchitheka kwe-slag, ukuguguleka, noma ukuguquka komgodi lapho kuvuleka khona i-nozzle. I-nozzle eyonakele izophazamisa ukugxila kanye nokuqina kokugeleza kwegesi futhi kumele ishintshwe ngesikhathi esifanele.
• Ukuphakama kwe-nozzle: Ibanga eliphakathi kwe-nozzle kanye nobuso bepuleti (ngokuvamile i-0.5-1.5mm) libaluleke kakhulu. Ukuphakama kakhulu kuzokwenza ukugeleza kwegesi kuhlakazeke, futhi umphumela wokuqhuma kwe-slag uzoba buthaka; ukwehla kakhulu kuzoshayisana kalula nepuleti futhi kulimaze i-nozzle.

2.Amalensi okukhanya

• Ukuhlanzeka: Uma isibuko esivikelayo kanye nesibuko esigxilile kungcolisiwe, kuzonciphisa amandla e-laser, okuholela ekunciphiseni ikhono lokusika kanye nokwakheka kwama-burrs. Hlanza njalo izibuko nge-anhydrous ethanol kanye nephepha lelensi.
• Ikhwalithi: Hlola noma yimuphi umonakalo omncane noma ukuguga kwengubo ezibukweni okungenzeka kungabonakali emehlweni. Zishintshe uma kudingeka.

3. Ugongolo lwe-Laser

• Ukuqina kogongolo: Isikhungo sembobo ye-nozzle kumele sivumelane kahle nesikhungo se-laser beam. Uma zingagxilile, kuzobangela ukusikeka okungalingani, uhlangothi olulodwa lube bushelelezi kanti olunye uhlangothi lunezimbobo.
• Indlela yokulinganisa: Namathisela ungqimba lwetheyiphu yokufihla ngaphambili kwe-nozzle, vula i-pulse, bese ubheka ukuthi imbobo iphakathi kwe-nozzle. Uma ingaphandle kwe-centre, ukulinganisa kufanele kwenziwe ngokwencwadi yemiyalelo yemishini.
• Ukuqina kwemishini: Hlola ukudlidliza kwemishini noma ukukhululeka kwayo, njengoba lokhu kungathinta ukuqina kokusikwa.

Isinyathelo 3: Izinto Ezisetshenziswayo Nezinye Izinto

Izinto ngokwazo

• Ikhwalithi yobuso: Uwoyela, ukugqwala, kanye nokwembozwa ebusweni beshidi kungandisa ubunzima bokusika futhi kubangele ama-burrs. Hlanza ishidi ngaphambi kokusika.
• Uhlobo lwezinto: Izinhlobo ezahlukene zezinto zokwakha zinezinhlobo ezahlukene ze-alloy kanye nokwelashwa kwendawo, okungathinta ukusebenza kokusika. Uma ungakwazi ukusika kahle njalo, zama i-batch ehlukile noma uhlobo lwezinto zokwakha.
• Ubukhulu bezinto: Qinisekisa ukuthi amandla e-laser yakho anele ukusika ubukhulu. Amandla anganele azoholela ngqo ekusikeni okungaphelele kanye nama-burrs.

Isifinyezo kanye nohlu lokuhlola lokuxazulula izinkinga ngokushesha

Uma uhlangabezana nezinkinga ze-burr, landela lolu chungechunge ukuze uxazulule izinkinga ngokushesha:

1. Okokuqala, hlola igesi!

• Ukuze usike insimbi yekhabhoni: Sebenzisa i-oxygen bese uhlola ukuthi ingcindezi yanele yini.
• Ukuze usike insimbi engagqwali/i-aluminium: Sebenzisa i-nitrogen emsulwa kakhulu bese uhlola ubumsulwa kanye nengcindezi.

2. Okulandelayo, lungisa ukugxila!

• Yenza isivivinyo sokugxila ukuze uthole indawo efanele yokugxila. Kumapuleti amancane, zama ukususa ukugxila okungekuhle.

3. Bese, yenza ngcono isivinini namandla!

• Yenza izivivinyo zamapharamitha ukuthola inhlanganisela "yamandla esivinini" ngaphandle kwama-burrs.

4. Ngemva kwalokho, hlola i-nozzle kanye nendlela yokukhanya!

• Shintsha i-nozzle encane enobubanzi ezwakala futhi ibukeka kahle.
• Hlola futhi uhlanze izibuko.
• Linganisa ukugxila kwe-nozzle kanye nomsebe we-laser.

5. Okokugcina, cabanga ngezindaba zezinto ezibonakalayo!

• Hlanza ubuso beshidi noma uzame elinye ishidi ukuze ulihlole.

Ngokulandela le nqubo yokuxazulula izinkinga ehlelekile, izinkinga eziningi ze-burr ekusikeni kwe-laser yepuleti elincane zingaxazululwa ngempumelelo.
