Shawarwarin masana'antu don yanke bugun jini na faranti na aluminum

Don yanke laser na zare na aluminum, ainihin shine a sarrafa fitowar bugun jini na laser daidai (mita, zagayowar aiki, da sauransu) kuma a dumama kayan lokaci-lokaci don inganta shigarwar zafi, don daidaita ingancin yankewa da inganci a ƙarƙashin babban haske da ƙarfin zafi na aluminum.

Muhimman sigogin tsari da shawarwarin ingantawa

Ga shawarwari masu zuwa don yanke faranti na aluminum bisa ga kauri daban-daban, an taƙaita su daga binciken ilimi:

Manufofin Tsarin

Yankewa mai inganci (rage slag na ratayewa, inganta kammala sashe)

• Kauri mai dacewa: matsakaicin kauri (misali 4mm)
• Shawarwarin mahimman sigogi:
• Yanayin Laser: Ana ba da shawarar yanayin bugun jini
• Iskar Gas Mai Taimakawa: Ana ba da shawarar Nitrogen ko Argon
• Muhimman abubuwa: ƙara matsin lamba na iska don haɓaka ƙarfin busawa; sarrafa shigar da zafi na laser don guje wa narkewar da ya wuce kima.

Yanke farantin da ya fi inganci/kauri (neman sauri ko yanke farantin da ya fi kauri)

• Kauri mai dacewa: faranti matsakaici da nauyi (misali 10-15mm)
• Shawarwarin mahimman sigogi:
• Yanayin Laser: Ana iya amfani da bugun bugun ruwa mai ci gaba ko bugun zagayowar aiki mai girma
• Iskar Gas: Ana iya gwada iskar oxygen
• Muhimman bayanai: Iskar oxygen mai zafi na waje na iya ƙara kuzari da inganta ikon yanke faranti masu kauri; amma sashin zai yi oxidize kuma ya zama mai kauri, kuma ana buƙatar sarrafawa na gaba.

Babban daidaito/yanke takarda (ana amfani da shi a fannoni masu daidaito kamar sararin samaniya)

• Kauri mai dacewa: faranti mai siriri (misali 0.5-2mm)
• Shawarwarin mahimman sigogi:
• Yanayin Laser: Ana ba da shawarar yanayin bugun mita mai yawa
• Iskar Gas Mai Taimakawa: Ana ba da shawarar Nitrogen
• Muhimman bayanai: amfani da saurin yankewa mafi girma da kuma matsin lamba mai dacewa; sarrafa shigar da zafi don rage yankin da zafi ya shafa (ana iya sarrafa shi a ƙasa da mita 20).

Nassoshi na sigogi masu inganci gabaɗaya (misali ƙarfe aluminum na 4mm 2219)

Domin cimma ka'idojin yankewa na matakin 1 (rage rataye slag da ƙarancin kauri), wani bincike ya gano cewa mafi kyawun kewayon sigogi shine:

• Ƙarfin Laser:>4.5 kW
• Gudun yankewa: 3-4 m/min
• Matsin iska mai taimako: 1.3 MPa

Manyan Kalubale da Mafita Masu Manufofi

Manyan ƙalubale da mafita ga yanke aluminum sune kamar haka:

1. Babban ƙarfin haske

• Kalubale: Aluminum yana da ƙarfin haske akan laser, musamman laser fiber na kusa da infrared, da ƙarancin amfani da makamashi.
• Magani: Yi amfani da na'urar laser mai tsarin "hana tunani"; yi amfani da bugun kuzari mai ƙarfi don karya kayan a matakin farko na yankewa, kuma hasken zai ragu bayan an sami ramin farko.

2. Saurin watsa zafi da kuma sauƙin ratayewa

• Kalubale: Zafi yana raguwa da sauri, kuma ƙarfe mai narkewa a ƙasan wurin da aka yanke ya taru don ya zama tarko wanda yake da wahalar cirewa.
• Magani: Idan aka kwatanta da laser mai ci gaba, laser na bugun jini zai iya sarrafa shigar zafi daidai; Ƙara matsin iskar gas mai taimako (kamar ≥ 1.3MPa), inganta ƙarfin yanke iska don hura slag; Inganta matsayin mayar da hankali, yawanci a ƙasa da saman farantin.

3. Ingancin sashe na yankewa da buƙatun tsari na gaba

• Kalubale: Sashen yankewa zai samar da wani Layer da aka sake narkewa. Idan ana buƙatar walda daga baya, zai shafi ramukan walda.
• Magani: Idan ana buƙatar walda bayan yankewa, ya kamata a sarrafa tsarin sosai, kuma kauri na layin sake narkewar dinkin ya kamata a sarrafa shi ƙasa da 136μm don rage porosity na walda yadda ya kamata.

Jerin muhimman abubuwan da suka shafi aikin masana'antu

• Zaɓin iskar gas:bin hanyar yankewa mai inganci wanda ba ya haɗa da iskar oxygen (musamman buƙatar walda bayan haka), a ba da fifiko ga nitrogen ko argon mai tsafta. Ana iya kimanta iskar oxygen lokacin da ake bin diddigin kauri da saurin yankewa kuma iskar oxygen a sashe ba matsala ba ce.
• Jerin gyaran sigogi:Ana ba da shawarar a gyara wasu masu canji da gyara kurakurai a cikin wannan tsari: matsayin mayar da hankali → nau'in iskar gas mai taimako da matsin lamba → ƙarfin laser → saurin yankewa → sigogin bugun jini (idan ana amfani da yanayin bugun jini).
• Kayan aiki da aminci:don tabbatar da cewa laser ɗin yana da ikon magance kayan da ke haskakawa sosai; Lokacin yanke farantin aluminum, fashewar walƙiya ta fi ƙarfi. Ya zama dole a tabbatar da cewa tsarin cire ƙura yana da tasiri kuma an kare kayan aiki da ma'aikata.
• Yanke gwaji da dubawa:Dole ne a yi yanke gwaji kafin yankewa. Don duba inganci, da fatan za a duba: lura da gani na slag da ke rataye a ƙasa; ƙaiƙayin sashin gane yanayin hulɗa; auna kauri na Layer da aka narke (idan akwai manyan buƙatu).

Takaitawa da Shawarwari na Ƙarshe

Tushen farantin aluminum na laser mai zare mai pulsed shine"daidaitaccen sarrafa zafi"Ana ba da shawarar wannan hanyar:

1. Bayyana fifiko:Da farko ka tantance ko babban burinka shine ingancin sashe, ingancin yankewa ko kuma aikin walda na gaba.

2. Dangane da kauri na manyan sigogi:Duba teburin da ya gabata, gwargwadon kauri da fifikon farantin aluminum ɗinku, ƙayyade yanayin laser na farko da nau'in iskar gas.

3. Kyakkyawan gyara kurakurai da tabbatarwa:Ana gudanar da gyaran kurakurai mai kyau a kusa da matsin iska mai taimako da saurin yankewa, kuma ana aiwatar da tabbatar da yankewar gwaji sosai.
