Mokhoa oa ho rarolla bothata ba ho phunyeha ha poleiti e teteaneng ka masalla a amang ho seha

Ha ho seha lipoleiti tse teteaneng ka laser, masalla (slag) a hlahisoang ke ho phunyeha a ama boleng ba ho seha ke bothata bo tloaelehileng empa bo ka ntlafatsoa. ​​Masalla ana hangata a bakoa ke taolo e sa lokelang ea matla nakong ea ts'ebetso ea ho phunyeha, ho se lumellane ha liparamente tsa khase kapa liparamente tse sa utloahaleng tsa ts'ebetso. Tse latelang ke litharollo tsa sistimi le likhothaletso tsa ntlafatso:

ntlafatso ea ts'ebetso ea ho phunyeletsa

1. Ho sebedisa lesoba le ntseng le tswela pele (lesoba le nang le mekhahlelo)

• Bakeng sa lipoleiti tse teteaneng (mohlala, tse fetang 15mm), qoba ho sebelisa ho phunyeha ha matla a phahameng hanngoe feela, 'me u sebelise keketseho ea matla a hateletsoeng kapa ho phunyeha ha likarolo ho kenella butle-butle thepa le ho fokotsa ho phatloha ha slag.
• Mokhoa oa ts'ebetso: Beha paramethara ea "ho phunyeha ka likarolo" ho software ea ho seha, qala ka ho futhumatsa pele ka matla a tlase, ebe butle-butle u eketsa matla a ho kenella.

2. Fetola diparamente tsa ho phunyeha

• Fokotsa matla a tlhoro le ho eketsa nako ea ho phunyeha:fokotsa ho phatloha ha thepa e qhibilihisitsoeng e bakoang ke ho phatloha ha matla hang-hang.
• Eketsa maqhubu a ho phunyeha (potoloho ea mosebetsi):Laola morethetho oa tlhahiso ea matla a pulse ea laser ho qoba ho qhibiliha ho feteletseng.
• Mohlala oa litšupiso tsa paramethara (ho sebelisoa tšepe ea khabone ea 20mm e le mohlala):
• Matla: 1000-1500W (e fetotsoe ho latela bokhoni ba lisebelisoa)
• Nako ea ho phunyeletsa: metsotsoana e 1.5-3
• Maqhubu a ho otla ha pelo: 200-500Hz
• Khatello ea khase e thusang: phetoho ea mekhahlelo (sheba ka tlase)

Taolo ea khase e thusang

1. Mofuta oa khase le ntlafatso ea khatello

• Tšepe ea khabone: Oksijene (O₂) e sebelisoa e le khase e thusang, empa khatello e hloka ho laoloa. Mokhahlelong oa ho phunyeha, khatello e tlase (0.5-1bar) e ka sebelisoa pele, ebe khatello ea ho seha e ka fetoloa khatello e phahameng (1.5-2.5bar) kamora ho kenella ho qoba karabelo e feteletseng ea oksijene ho hlahisa slag e ngata.
• Tšepe e sa ruseng/tšepe e kopantsoeng: sebelisa naetrojene (N₂) kapa moea, sebelisa khatello e mahareng le e tlase (6-10bar) bakeng sa ho phunyeletsa, 'me u fetohele ho seha naetrojene e hloekileng haholo ka mor'a ho kenella.

2. Tieho ea khase le ho koaloa pele ho nako

• Fetola khase pele ho phunya ho phethoa: fetohela ho diparamitha tsa khase bakeng sa ho seha ha ho kenella ho se ho tla phethelwa ho thusa ho ntsha slag ka hara lesoba.
• Eketsa nako ea pele ho ho foka ha khase: foka metsotsoana e 0.5-1 pele ho ho phunya ho hloekisa sebaka sa lesoba le ho pholisa thepa e potolohileng.

Boemo ba ho Tsepamisa Maikutlo le Phetoho ea Nozzle

1. Sebaka sa ho tsepamisa maikutlo

• Ha o phunyeletsa, sebedisa tekanyo e fokolang ya ho tlosa focus (sepheo se ka tlase ho bokahodimo ba poleiti) ho eketsa lesoba le ho nolofatsa ho ntsha ha slag. Mohlala, tshepe ya khabone ya 20mm e ka beha ntlha ya focus ho 3-5mm ka tlase ho bokahodimo.
• Kamora ho kenella, lokisa tlhokomelo ho ea boemong bo botle ho latela litlhoko tsa ho seha.

2. Khetho ea li-nozzle le bolelele ba tsona

• Sebelisa li-nozzle tse bophara bo boholo (tse kang φ2.0-φ3.0mm) ho ntlafatsa tšireletso ea khase le ho khothaletsa ho ntšoa ha slag.
• Netefatsa hore bophahamo ba nozzle bo mahareng (hangata 1.0-2.0mm) ho qoba ho hasana ha khase ho bakoang ke tšenyo e phahameng haholo le matheba a bakoang ke ho theoha haholo.

Tsebo ea mokhoa oa ts'ebetso le mananeo

1. Lesoba la loto le tjhekilweng esale pele

• Bakeng sa lipoleiti tse botenya bo phahameng haholo (mohlala,> 30mm), masoba a manyane a pilot a bophara bo ka tjhekwa ka mechine pele, ebe ho sehwa ka laser ho ka qalwa ho tloha masobeng a pilot ho qoba ho phunyeha ka ho toba.

2. Beha ntlha ea ho phunyeletsa e fapaneng

• Ha o etsa mananeo, etsa hore ntlha ya masoba e khelohe moleng wa sebele wa contour ka 1-2mm, ebe o tloha ntlheng ya offset ho ya moleng wa contour nakong ya ho seha ho qoba sebaka sa ho bokella masalla.

3. Ho seha ntlafatso ea tsela

• Mapetso a spiral kapa libaka tsa ho qala tsa ho seha tse chitja li sebelisoa ho jala lerōle sebakeng se sa seheng.

Tlhahlobo ea lisebelisoa le tlhokomelo

1. Boemo ba laser

• Hlahloba hore na matla a tlhahiso a tsitsitse, etsa bonnete ba hore lense/seipone se sireletsang se hloekile, 'me u qobe ho phunyeha ho sa lekaneng ho bakoang ke ho fokotseha ha matla.

2. Bohloeki le phallo ea khase

• Netefatsa hore khase e hloekile (haholo-holo naetrojene/oksijene), 'me u hlahlobe khafetsa hore na tsela ea khase e koetsoe kapa ea lutla.

3. Nozzle e tsamaellana le karolo ea optical.

• Kamehla lekanyetsa botebo ba nozzle le lehlaseli la laser ho netefatsa hore phallo ea khase e lekana.

Lisebelisoa le Mabaka a Tikoloho

1. Phekolo ea poleiti holim'a bokaholimo

• Hloekisa lera la mafome, letheba la oli kapa lesela le holim'a poleiti pele u seha ho fokotsa ho kenella ha litšila karabelong.

2. Ho batalla ha poleiti

• Netefatsa hore poleiti e bataletse 'me u qobe likheo tse bakang ho lutla ha khase le ho bonahatsa matla.

Khothaletso ea ts'ebetso ea ho lokisa liphoso tsa paramethara

1. Taba ea pele, lokisa liparamente tse ling, butle-butle fetola nako le matla a ho phunyeha, hlokomela bongata ba slag e hlahisoang, 'me u fumane ntlha ea ho leka-lekanya.

2. Rekota diparamitha tsa ntlafatso mme o thehe database ya tshebetso ya thepa/botenya bo fapaneng.

3. Teko le netefatso: ho etsoa liteko tse 'maloa tsa ho phunyeha holim'a litšila ho netefatsa hore slag e fokotsehile pele ho sehoa ka molao.

Kakaretso: Tlhahlobo e Potlakileng ea Lintlha tsa Bohlokoa

Ka tokiso e felletseng e boletsoeng ka holimo, masala a teteaneng a ho phunyeha ha poleiti a ka fokotsoa haholo, 'me boleng ba ho seha le katleho li ka ntlafala. Haeba bothata bo ntse bo tsoela pele, ho kgothaletswa ho ikopanya le moetsi oa lisebelisoa bakeng sa liteko tsa hardware kapa tšehetso ea ts'ebetso.
