Momwe mungathetsere vuto la ma burrs pakudula mbale zoonda ndi laser

Kuwoneka kwa ma burrs pakudula kwa laser kwa mbale zopyapyala ndi vuto lofala kwambiri. Izi nthawi zambiri sizimachitika chifukwa cha chinthu chimodzi koma zimachitika chifukwa cha zotsatira za zinthu zingapo monga zida, magawo, zipangizo, ndi mpweya. Kuti tithetse vutoli mwadongosolo, titha kutsatira njira yothetsera mavuto kuyambira yosavuta mpaka yovuta komanso kuchokera ku mapulogalamu kupita ku zida. Kenako, tifotokoza mwatsatanetsatane za ntchito ndi mayankho enieni a gawo lililonse mwatsatanetsatane:

Gawo 1: Kuyang'ana ndi kusintha ma parameter apakati (malo ovuta kwambiri)

1. Malo olunjika

• Malo owunikira ndi chimodzi mwa zinthu zofunika kwambiri zomwe zimakhudza khalidwe la kudula. Kuwunikira kolakwika kungapangitse kuti mphamvu zisamangidwe, zomwe zimapangitsa kuti zikhale zosatheka kuchotsa slag bwino.
• Zizindikiro: Kuyang'ana kwambiri kapena kotsika kwambiri kumapangitsa kuti slag imamatire pansi (burrs).

Yankho:

• Chitani calibration focus: Choyamba, onetsetsani kuti focus ya zida zanu ndi yolondola. Gwiritsani ntchito focus gauge kapena automatic calibration function.
• Chitani mayeso owunikira: Pa chidutswa chodulidwa, dulani mzere wowongoka kapena bwalo pamalo osiyanasiyana owunikira (mwachitsanzo, kuyambira -1mm mpaka +1mm, ndi malo ocheperako a 0.2mm), ndipo onani malo omwe ali ndi ma burrs ochepa kwambiri. Pa mbale zoonda, nthawi zambiri amalimbikitsidwa kugwiritsa ntchito negative defocusing (mwachitsanzo, focus ili pansi pa pamwamba pa mbale, pa mtunda wa pafupifupi 1/3 mpaka 1/2 ya makulidwe a mbale), zomwe zingapangitse kudula kwakukulu ndikuthandizira kutsika kwa slag ndi kuyenda kwa mpweya.

2. Mpweya wothandizira

Mtundu wa gasi ndi chiyero chake:

• Kudula chitsulo cha kaboni: Muyenera kugwiritsa ntchito mpweya. Mpweya umagwira ntchito pa kuyaka, kupereka mphamvu yowonjezera ndikupanga chitsulo chosasungunuka bwino, chomwe chimatha kuchotsedwa mosavuta ndi mpweya. Ngati mpweya kapena nayitrogeni ikugwiritsidwa ntchito, ma burrs ambiri akuda amapangidwa.
• Kudula chitsulo chosapanga dzimbiri, aluminiyamu: Muyenera kugwiritsa ntchito nayitrogeni woyeretsedwa kwambiri. Ntchito ya nayitrogeni ndikutulutsa chitsulo chosungunuka ndikuletsa kukhuthala. Ngati kuyera kwa nayitrogeni sikukwanira (komwe kukuyembekezeredwa kuti kukhale pamwamba pa 99.9%) kapena kupanikizika kuli kotsika kwambiri, ma burrs adzapangika pansi pa chinthucho chifukwa cha kukhuthala komanso kuzizira kosakwanira.

Kupanikizika kwa mpweya:

• Kupanikizika kochepa kwambiri: Kulephera kuwononga bwino matope, zomwe zimapangitsa kuti ma burrs aziunjikana pansi.
• Kupanikizika kwambiri: Pa mbale zoonda, kupanikizika kwambiri kungapangitse ma vortice pamalo odulidwawo, zomwe zimafooketsa mphamvu yotulutsa zinyalala ndipo mwina zimayambitsa malo odulidwa mopanda kukhazikika komanso ngakhale zotupa zosungunuka zomwe zimakhala zovuta kuchotsa.

Yankho:Onani magawo omwe akulimbikitsidwa ndi wopanga zida kutengera mtundu wa chipangizocho ndi makulidwe ake, ndipo sinthani bwino moyenerera. Mwachitsanzo, podula chitsulo cha kaboni cha 1mm, kuthamanga kwa okosijeni nthawi zambiri kumakhala pakati pa 0.8-1.2Bar.

3. Kudula liwiro ndi mphamvu ya laser

• Ziwirizi ziyenera kufanana bwino.
• Liwiro lothamanga kwambiri: Mphamvu yolowera siili yokwanira, zinthuzo sizisungunuka ndi kudulidwa kwathunthu, zomwe zimasiya ma burrs okhazikika komanso omata pansi.
• Liwiro lochedwa kwambiri: Mphamvu zambiri zomwe zimalowa, zomwe zimapangitsa kuti zinthuzo zisungunuke kwambiri, zomwe zimapangitsa kuti pamwamba pake padulidwe mopanda kukonzedwa bwino komanso kuti pakhale ziphuphu zosungunuka zovuta kuchotsa.
• Kusagwirizana kwa mphamvu: Mphamvu yotsika kwambiri ndi yofanana ndi liwiro lothamanga kwambiri, ndipo mphamvu yokwera kwambiri ndi yofanana ndi liwiro lochedwa kwambiri.

Yankho:

• Chitani mayeso a magawo: Konzani magawo ena ndikusintha liwiro lodulira ndi mphamvu kuti mupeze kuphatikiza kwabwino kwambiri kwa "liwiro-mphamvu". Njira yabwino yodulira ndi mawonekedwe ofanana ndi maluwa omwe amafalikira pansi mofanana.

Gawo 2: Kuyang'ana momwe zinthu zilili pa zipangizo ndi zida

Ngati kusintha kwa magawo sikuthandiza, chipangizocho chiyenera kufufuzidwa.

1. Mphuno

• Kusankha Manotsi: Kugwiritsa ntchito notsi yokhala ndi mainchesi akuluakulu (monga φ2.0 kapena kupitirira apo) sikuthandiza kuti mpweya uyende bwino. Pa mbale zoonda, ndi bwino kugwiritsa ntchito notsi yaying'ono (monga φ1.0 kapena φ1.5), yomwe ingapangitse mpweya kuyenda mofulumira kwambiri komanso kukhala ndi mphamvu yabwino yotulutsa slag.
• Mkhalidwe wa nozzle: Yang'anani ngati pali kutayikira kwa matope, kuwonongeka, kapena kusintha kwa mpweya potsegula nozzle. Nozzle yowonongeka idzasokoneza kukhazikika kwa mpweya ndi kukhazikika kwake ndipo iyenera kusinthidwa nthawi yake.
• Kutalika kwa nozzle: Mtunda pakati pa nozzle ndi pamwamba pa mbale (nthawi zambiri 0.5-1.5mm) ndi wofunika kwambiri. Kukwera kwambiri kungapangitse kuti mpweya utuluke, ndipo mphamvu yotulutsa slag idzakhala yofooka; kutsika kwambiri kudzagundana mosavuta ndi mbaleyo ndikuwononga nozzle.

2.Magalasi a kuwala

• Ukhondo: Ngati galasi loteteza ndi galasi loyang'ana kwambiri zaipitsidwa, zimachepetsa mphamvu ya laser, zomwe zimapangitsa kuti luso lodula lichepe komanso kuti ma burrs apangidwe. Tsukani magalasi nthawi zonse ndi anhydrous ethanol ndi lens paper.
• Ubwino: Yang'anani ngati pali kuwonongeka kulikonse kwa microscopic kapena kukalamba kwa chophimba pagalasi chomwe sichingawonekere ndi maso. Chisintheni ngati pakufunika kutero.

3. Mtambo wa Laser

• Kuzungulira kwa denga: Pakati pa dzenje la nozzle payenera kukhala patali ndi pakati pa denga la laser. Ngati sizili patali, zingayambitse kudula kosafanana, mbali imodzi ili yosalala ndipo mbali inayo ili ndi ma burrs.
• Njira yoyezera: Ikani tepi yophimba kutsogolo kwa nozzle, yatsani kugunda kwa mtima, ndikuwona ngati dzenjelo lili pakati pa nozzle. Ngati sili pakati, kuyezera kuyenera kuchitidwa motsatira buku la zida.
• Kukhazikika kwa zida: Yang'anani ngati makina akugwedezeka kapena kusasunthika kwa zida, chifukwa izi zingakhudze kukhazikika kwa kudula.

Gawo 3: Zipangizo ndi Zinthu Zina

Zinthu zokha

• Ubwino wa pamwamba: Mafuta, dzimbiri, ndi zokutira pamwamba pa pepalalo zimatha kuwonjezera zovuta zodula ndikuyambitsa ziphuphu. Tsukani pepalalo musanadule.
• Mtundu wa zinthu: Mitundu yosiyanasiyana ya zinthu ndi magulu osiyanasiyana ali ndi mitundu yosiyanasiyana ya alloy ndi mankhwala ake pamwamba, zomwe zingakhudze momwe kudula kumagwirira ntchito. Ngati simungathe kudula bwino nthawi zonse, yesani gulu lina kapena mtundu wina wa zinthuzo.
• Kukhuthala kwa zinthu: Tsimikizirani kuti mphamvu ya laser yanu ndi yokwanira kudula makulidwe. Mphamvu yosakwanira idzapangitsa mwachindunji kudula kosakwanira ndi ma burrs.

Chidule ndi Mndandanda Wofufuza Mavuto Mwachangu

Mukakumana ndi mavuto a burr, tsatirani izi kuti muthetse mavuto mwachangu:

1. Choyamba, yang'anani mafuta!

• Podula chitsulo cha kaboni: Gwiritsani ntchito mpweya wa okosijeni ndipo onani ngati mphamvu yake ndi yokwanira.
• Podula chitsulo chosapanga dzimbiri/aluminiyamu: Gwiritsani ntchito nayitrogeni woyeretsedwa kwambiri ndipo yang'anani kuyera ndi kupanikizika.

2. Kenako, sinthani cholinga chanu!

• Chitani mayeso a focus kuti mupeze malo abwino kwambiri ofocus. Pa ma plate owonda, yesani kuchotsa focus mu negative.

3. Kenako, konzani liwiro ndi mphamvu!

• Chitani mayeso a magawo kuti mupeze kuphatikiza kwa "liwiro-mphamvu" popanda ma burrs.

4. Pambuyo pake, yang'anani nozzle ndi njira yowunikira!

• Sinthani cholumikizira chaching'ono chomwe chimamveka bwino komanso chikuwoneka bwino.
• Yang'anani ndi kuyeretsa magalasi.
• Linganizani kuchuluka kwa nozzle ndi kuwala kwa laser.

5. Pomaliza, ganizirani nkhani zakuthupi!

• Tsukani pamwamba pa pepalalo kapena yesani pepala lina kuti muyese.

Potsatira njira yokhazikika yothanirana ndi mavuto, mavuto ambiri a burr mu kudula kwa laser ya thin plate amatha kuthetsedwa bwino.
