Indlela yokusombulula i-slag enamathelayo xa i-laser isika ipleyiti ye-aluminium

I-laser cutting aluminium slag (ekwaziwa ngokuba yi-hanging slag, i-slag) yingxaki eqhelekileyo, ikakhulu yi-thermal conductivity ephezulu ye-aluminium, i-low melting point, i-easy oxidation kunye ne-metallic state viscosity kunye nezinye iimpawu. Ukuze kusonjululwe ingxaki ngendlela ecwangcisiweyo, kuyimfuneko ukwenza ngcono igesi, iiparameter, izixhobo, izixhobo kunye nenkqubo 5. Oku kulandelayo kubonelela ngeseti epheleleyo yezisombululo:

Isitshixo esingundoqo: ukukhethwa kwegesi encedisayo kunye nokwenza ngcono (le yeyona nxalenye ibalulekileyo)

1. I-nitrogen ecocekileyo kakhulu iyathandwa

• Umgaqo: I-nitrogen njengegesi engasebenziyo inokuthintela ngempumelelo ukunyibilika kwe-aluminium kwaye inciphise ukwakheka kwe-aluminium oxide (Al₂O₃) sticky residue. Kwangaxeshanye, i-nitrogen enoxinzelelo oluphezulu inokuvuthela ulwelo lwe-aluminium olunyibilikisiweyo luye ezantsi ukusuka kwindawo evulekileyo, endaweni yokuqokelelwa ecaleni.
• Imfuneko yococeko: ≥ 99.99% (99.995% nangaphezulu iyacetyiswa). Ukungabikho kococeko yenye yezona zinto ziphambili ezibangela ukuba i-slag inamathele.
• Iimfuno zoxinzelelo: ngokwendlela ipleyiti ehlengahlengiswa ngayo ubukhulu bayo, idla ngokuba phezulu (njengokusika ipleyiti ye-aluminium eyi-3mm ukuya kwi-1.5-2.0MPa). Uxinzelelo olunganelanga aluyiphehli kakuhle into enyibilikayo.

2. Umoya ocinezelweyo osemgangathweni ophezulu (enye indlela yezoqoqosho)

• Iimeko ezisebenzayo: iimfuno zomgangatho ophantsi womphezulu aziphezulu, okanye azikho kwipleyiti ye-aluminium ebhityileyo (efana ne-≤ 3mm) yoomatshini abarhabaxa.
• Iimeko eziyimfuneko:
• Kufuneka ixhotyiswe ngezixhobo zokomisa ezisebenza kakuhle efrijini kunye nezihluzo ezichanekileyo ukuqinisekisa ukuba umoya awunamanzi kwaye awunaoyile. Ukufuma kunye neoyile kuya kwandisa i-oxidation ye-aluminium kunye nokunamathela kwe-slag.
• Uxinzelelo kufuneka luzinze ngokwaneleyo.

3. Ioksijini (injongo ekhethekileyo)

• Umgaqo: Sebenzisa i-oxidation reaction ukuze unike ubushushu obongezelelekileyo kwaye wonyuse isantya sokusika. Nangona kunjalo, inani elikhulu le-alumina slag eqinileyo nerhabaxa liya kuveliswa ngokuqinisekileyo, nto leyo edla ngokungacetyiswa xa kusikwa ngaphandle kokunamathela kwe-slag, kodwa kuphela kwiimeko ezifuna iimfuno eziphantsi kakhulu zomphezulu okanye ukucutshungulwa okulandelayo.

ukusika iparameter ngcono

Iiparameters mazifaniswe negesi ukuze kulungiswe ingxaki kwinkqubo.

1. Amandla kunye nesantya esilinganiselweyo:

• Amandla aphezulu kakhulu/isantya sicotha kakhulu: amandla agqithisileyo abangela ukunyibilika kwe-aluminiyam ngokugqithisileyo, ichibi elinyibilikisiweyo liba likhulu, igesi kunzima ukuyivuthela, kwaye kuyenziwa i-slag esezantsi engqukuva.
• Amandla aphantsi kakhulu/akhawuleza kakhulu: amandla aneleyo, izinto azinqunyulwanga okanye izantsi lipholiswe ngokukhawuleza kakhulu, ukunyibilika kuya kuqina emaphethelweni ngaphambi kokuba kuphephuke.
• Indlela yokulungisa iimpazamo: ngokweeparameter ezicetyiswayo, uvavanyo lwe-speed ladder lwenziwa ukuze kufunyanwe "indawo entle" enqumla nje ize ixhome inkunkuma encinci".

2. Ukuphindaphinda kunye nomjikelo womsebenzi:

• Ukunciphisa i-frequency kunye nokulungisa umjikelo womsebenzi ngamanye amaxesha kunceda ukulawula ubushushu kunye nokunciphisa ubushushu obuphantsi. Kwiipleyiti ezincinci, ii-frequency eziphezulu zingasetyenziswa.

3. Indawo yokugxila:

• Zama ukunciphisa ukugxila kancinci (ukungagxili kakuhle) ukuze amandla agxile ngakumbi kwisiqingatha esisezantsi sepleyiti, nto leyo enceda ekukhupheni ukunyibilika okuvela ezantsi. Le yindlela esebenzayo yokuphucula i-slag exhonyiweyo esezantsi. Kufuneka ilungiswe ngokwemeko yokwenyani.

Imeko yeZixhobo kunye nezinto ezisetyenziswayo

1. Ukuhlolwa kunye nokukhetha i-nozzle:

• Imeko: Qinisekisa ukuba umlomo awugugi, awuguquki kwaye awuguquki. Umlomo ogugileyo uya kubangela ukuba ukuhamba komoya kuphazamiseke kwaye ukuvuthuza kwe-slag kube buthathaka.
• Ububanzi: Ngokuqhelekileyo kusetyenziswa umlomo omkhulu (ofana ne-φ2.0mm okanye ngaphezulu) one-nitrogen enoxinzelelo oluphezulu, onokwenza isigqubuthelo esinamandla nesibanzi somqobo wokuhamba komoya.

2. Umgangatho we-beam:

• Qinisekisa ukuba ilensi yentloko yelaser (isibuko esijolisa amehlo, isibuko esikhuselayo) icocekile kwaye ayinangcoliseko, kwaye uqinisekise ukuba usasazo lwamandla omqadi luyafana kwaye luxineneyo.

Ukulungiselela izinto kunye nenkqubo

1. Umphezulu kunye nezinto zepleyiti ye-aluminiyam:

• Ukucoca: Susa ioyile, uthuli kunye nomaleko we-oxide kumphezulu wepleyiti ye-aluminiyam ngaphambi kokuba usike. Isixhobo sokucoca esikhethekileyo se-aluminiyam alloy singasetyenziswa.
• Uhlobo lwe-alloy: ukusebenza kwe-aluminium alloy eyahlukileyo kwahlukile. Ngokwesiqhelo uthotho olu-5 (olufana no-5052) kunoluhlu olu-6 (olufana no-6061) lungcono ukusika, i-slag encinci. I-Silicon, i-magnesium kunye nezinye izinto ezine-alloy viscosity ephezulu zinkulu.
• Umaleko we-oxide: ukuba kukho ulusu lwe-oxide oluqinileyo kumphezulu wepleyiti, lunokucolwa kancinci okanye lufakwe i-pickle.

2. Umgama wokusebenza:

• Qinisekisa ukuba umgama ukusuka kwi-nozzle ukuya kwipleyiti uhlala uhleli kwaye ufanelekile (ngesiqhelo yi-0.5-1.5mm). Ukuphakama kakhulu kuya kwenza uxinzelelo lwegesi lube buthathaka.

3. Ukugqobhoka kunye nelothe:

• Lungiselela iiparameter zokugqobhoza ukuze uthintele ukuchitheka kungaqokeleleki kumphezulu ngexesha lokugqobhoza.
• Sebenzisa iileyiti zangaphandle okanye iileyiti ze-arc ukuze uphephe ukuqokelelana kwe-slag ekuqaleni kwe-workpiece contour.

Unyango emva kokusikwa (isenzo sokulungisa)

Ukuba kusekho ukuxhonywa okuncinci kwe-slag, kungenziwa la manyathelo alandelayo:

1. Ukususwa ngokoqobo:Sebenzisa i-scraper, ibrashi yentsimbi engagqwaliyo okanye i-scouring pad ukuze uyisuse ngesandla. Kwi-slag eqinileyo yepleyiti enzima, kunokufuneka i-engile grinder encinci enevili le-nylon elikhethekileyo.

2. ukucoca ngamakhemikhali:Ukusetyenziswa kolwelo olukhethekileyo lokucoca i-aluminiyam okanye isisombululo se-alkaline esixutyiweyo, i-infringe wipe, inokunyibilikisa inxalenye ye-slag enamathelayo. Khumbula ukuphepha ukusebenzisa ii-asidi ezinamandla kunye ne-alkali, kwaye emva konyango kufuneka ihlanjwe kakuhle ngamanzi kwaye yomiswe.

3. Ukuqhumisa isanti:Kwiindawo zebhetshi okanye ezifuna umphezulu ofanayo ongematte, isanti encinci (njengeentsimbi zeglasi) ingasetyenziselwa ukuqhumisa isanti.

Ngophando olucwangcisiweyo kunye nokwenza ngcono okuchazwe apha ngasentla, ingxaki yokunamathela kwe-slag kwipleyiti ye-aluminiyam yokusika nge-laser inokulawulwa ngokufanelekileyo ukuze kufezekiswe ukusika okusemgangathweni. Isitshixo kukuqonda ukuba "ukucoca ngokufanelekileyo igesi ecocekileyo kakhulu" yeyona nto iphambili, kwaye zonke ezinye iiparameter zihambelana nale ngundoqo i-1.
