Izincomo zezimboni zokusika amapuleti e-aluminium nge-pulse

Ngokusika i-laser ye-aluminium pulse fiber, ingqikithi ukulawula ngokunembile ukuphuma kwe-pulse ye-laser (imvamisa, umjikelezo womsebenzi, njll.) nokushisa izinto ngezikhathi ezithile ukuze kulungiselelwe ukufakwa kokushisa, ukuze kulinganiswe ikhwalithi yokusika kanye nokusebenza kahle ngaphansi kokukhanya okuphezulu kanye nokuqhuba ukushisa kwe-aluminium.

Amapharamitha enqubo ayisihluthulelo kanye neziphakamiso zokwenza ngcono

Okulandelayo yizincomo zokusika amapuleti e-aluminium ngokwezinga elihlukene, ezifingqiwe ocwaningweni lwezemfundo:

Izinhloso Zenqubo

Ukusika kwekhwalithi ephezulu (nciphisa i-slag yokulenga, thuthukisa ukuqeda kwesigaba)

• Ubukhulu obusebenzayo: ubukhulu obuphakathi (isb. 4mm)
• Izincomo zepharamitha ebalulekile:
• Imodi ye-laser: Imodi yokushaya kwenhliziyo iyanconywa
• Igesi elisizayo: Kunconywa i-nitrogen noma i-Argon
• Amaphuzu abalulekile: ukwandisa umfutho womoya osizayo ukuze uthuthukise amandla okushaya kwe-slag; lawula okokufaka ukushisa kwe-laser ukuze ugweme ukuncibilika ngokweqile.

Ukusika ipuleti okujiyile/okusebenzayo kakhulu (ukuphishekela isivinini noma ukusika ipuleti elijiyile)

• Ubukhulu obusebenzayo: ipuleti eliphakathi nelisindayo (isb. 10-15mm)
• Izincomo zepharamitha ebalulekile:
• Imodi ye-laser: ingasebenzisa igagasi eliqhubekayo noma ukushaya komjikelezo ophakeme
• Igesi elisizayo: umoya-mpilo ungazanywa
• Amaphuzu ayinhloko: Ukusabela kwe-oxygen exothermic kungandisa amandla futhi kuthuthukise ikhono lokusika amapuleti aminyene; kodwa ingxenye izokhula ibe yi-oxidize futhi ibe yi-rough, futhi kudingeka ukucutshungulwa okulandelayo.

Ukusika okunembe kakhulu/okuneshidi (kusetshenziswa emikhakheni enembile njengendiza)

• Ubukhulu obusebenzayo: ipuleti elincane (isb. 0.5-2mm)
• Izincomo zepharamitha ebalulekile:
• Imodi ye-laser: imodi yokushaya kwenhliziyo evame kakhulu iyanconywa
• Igesi elisizayo: Kunconywa i-nitrogen
• Amaphuzu abalulekile: ukusetshenziswa kwesivinini sokusika esiphezulu kanye nokucindezela okusizayo okufanele; lawula ukufakwa kokushisa ukuze unciphise indawo ethintekile ekushiseni (kungalawulwa ngaphansi kwamamitha angu-20).

Ireferensi ejwayelekile yepharamitha yekhwalithi ephezulu (i-aluminium alloy engu-4mm 2219 njengesibonelo)

Ukuze kufezwe imigomo yokusika yezinga 1 (ukulenga okuncane kwe-slag kanye nokuqina okuphansi), ucwaningo luthole ukuthi ububanzi bepharamitha obufanele yilobu:

• Amandla e-laser: >4.5 kW
• Isivinini sokusika: 3-4 m/min
• Umfutho womoya osizayo: 1.3 MPa

Izinselele Eziyinhloko Nezixazululo Eziqondiwe

Izinselele ezinkulu kanye nezixazululo zokusika i-aluminium yilezi ezilandelayo:

1. Ukukhanya okuphezulu

• Inselele: I-Aluminium inokukhanya okunamandla kwi-laser, ikakhulukazi i-laser yefayibha eseduze ne-infrared, kanye nokusetshenziswa kwamandla aphansi.
• Isixazululo: Sebenzisa i-laser enendlela "yokulwa nokukhanya"; sebenzisa i-pulse enamandla aphezulu ukuze uhlukanise izinto esigabeni sokuqala sokusika, futhi ukukhanya kuzoncipha ngemva kokuba umgodi wokuqala usubunjiwe.

2. Ukushisa okusheshayo nokulenga okulula kwe-slag

• Inselele: Ukushisa kuyanyamalala ngokushesha, futhi insimbi encibilikisiwe phansi kwesibazi iyaqina ibe yi-slag okunzima ukuyisusa.
• Isixazululo: Uma kuqhathaniswa ne-laser eqhubekayo, i-laser ye-pulse ingalawula ukufakwa kokushisa ngokunembe kakhudlwana; Khulisa ingcindezi yegesi eyisizayo (njenge-≥ 1.3MPa), thuthukisa amandla okusika umoya ukuze kuqhunyiswe i-slag; Lungiselela indawo yokugxila, ngokuvamile ngaphansi kobuso bepuleti.

3. Ukusika ikhwalithi yesigaba kanye nezidingo zenqubo ezilandelayo

• Inselele: Ingxenye yokusika izoba ungqimba oluncibilikisiwe. Uma kudingeka ukushisela okulandelayo, kuzothinta ukuvuleka kweshidi.
• Isixazululo: Uma kudingeka ukushisela ngemva kokusika, inqubo kufanele ilawulwe ngokuqinile, futhi ubukhulu besendlalelo sokuncibilikisa umthungo wokusika kufanele bulawulwe ngaphansi kuka-136μm ukuze kuncishiswe ngempumelelo ukugoba kweshidi.

Uhlu lwamaphuzu abalulekile okusebenza kwezimboni

• Ukukhetha igesi:ukuphishekela i-incision yekhwalithi ephezulu engadingi i-oxidation (ikakhulukazi isidingo esilandelayo sokushisela), nikeza kuqala i-nitrogen noma i-argon ehlanzekile kakhulu. I-oxygen ingahlolwa lapho ukujiya kokusika kanye nesivinini kulandelwa futhi i-oxidation yesigaba akuyona inkinga.
• Ukulandelana kokulungisa amaphutha kwepharamitha:Kunconywa ukulungisa ezinye iziguquguquko nokulungisa amaphutha ngale ndlela: indawo yokugxila → uhlobo lwegesi olusizayo kanye nengcindezi → amandla e-laser → isivinini sokusika → amapharamitha okushaya (uma kusetshenziswa imodi yokushaya).
• Imishini nokuphepha:ukuqinisekisa ukuthi i-laser inekhono lokubhekana nezinto ezikhanyisa kakhulu; Lapho usika ipuleti le-aluminium, ama-spark splashes anamandla kakhulu. Kubalulekile ukuqinisekisa ukuthi uhlelo lokususa uthuli luyasebenza futhi imishini nabasebenzi bavikelekile.
• Ukusika nokuhlola kwesilingo:Ukusikwa kwesilingo kumele kwenziwe ngaphambi kokusikwa okusemthethweni. Ukuze uthole ukuhlolwa kwekhwalithi, sicela ubheke: ukubonwa okubonakalayo kokulenga kwe-slag phansi; ubulukhuni besigaba sokuzwa kwemodi yokuxhumana; ukulinganiswa kwe-microscope yobukhulu besendlalelo esincibilikisiwe (uma kunezidingo eziphezulu).

Isifinyezo kanye Nezincomo Zokugcina

Ingqikithi yepuleti le-aluminium yokusika i-laser e-pulsed fiber iwukuba"Ukulawula ukushisa okunembile". Kunconywa indlela elandelayo:

1. Okubaluleke kakhulu:Okokuqala thola ukuthi umgomo wakho oyinhloko ikhwalithi yesigaba, ukusebenza kahle kokusika noma ukusebenza kahle kokushisela okulandelayo.

2. Ngokusho kobukhulu bemingcele eyinhloko:bheka ithebula elidlule, ngokuya ngobukhulu bepuleti lakho le-aluminium kanye nokubaluleka kwalo, nquma imodi ye-laser yokuqala kanye nohlobo lwegesi.

3. Ukulungisa amaphutha nokuqinisekisa kahle:Ukulungisa amaphutha amancane kwenziwa ngokuhambisana nomfutho womoya osizayo kanye nesivinini sokusika, kanti ukuqinisekiswa kokusika kwesilingo kwenziwa ngokuqinile.
