Indlela yokusombulula i-burr eveliswa yintsimbi yokusika nge-laser

I-burr eveliswa xa isinyithi sokusika nge-laser yingxaki eqhelekileyo yenkqubo, nto leyo edla ngokubonisa ukuba inkqubo yokusika ayilunganga. Ukusombulula le ngxaki ngokucwangcisiweyo, kuyimfuneko ukujonga nokulungisa ukusuka kwiinkalo ezahlukeneyo ezifana nezixhobo, izixhobo, iiparameter zenkqubo kunye neegesi ezincedisayo.

Isikhokelo sokwenza ngcono okungundoqo kunye namanyathelo athile

1. Lungiselela iiparameter zenkqubo (zesinyithi sekhabhoni nezinye izinto)

• Amandla e-laser: amandla angonelanga yenye yezona zinto ziphambili ezibangela ii-burrs. Ukunyusa amandla ngokufanelekileyo kunokuqinisekisa ukuba isinyithi sinyibilike ngokupheleleyo. Nangona kunjalo, kufuneka kuqatshelwe ukuba amandla aphezulu kakhulu anokubangela ukuba ipleyiti itshise okanye ixhome i-slag.
• Isantya sokusika: Isantya sikhawuleza kakhulu, igalelo lamandla e-laser alanelanga, izinto azinyibiliki ngokupheleleyo, kwaye ziya kutshayelwa zibe zii-burrs ngumoya; ukuba isantya sicotha kakhulu, ukutsha kuya kuba nzima kwaye i-slag iya kunamathela. Lungisa isantya esifanelekileyo esihambelana namandla kunye nobukhulu bepleyiti. Ngokwesiqhelo ungavavanya iiparameter kuqala. Indawo yokugxila: Ukugxila okungalunganga kuya kubangela uxinano lwamandla olunganelanga. Vavanya ukugxila ukuze ufumane indawo efanelekileyo yobukhulu bepleyiti yangoku (ngokwesiqhelo xa usika intsimbi yekhabhoni, ukugxila kukumphezulu wepleyiti okanye ngaphantsi kancinci).

2. Qinisekisa ukuba igesi encedisayo ikwimeko entle kakhulu (eyona nto ibalulekileyo)

• Uhlobo lwegesi kunye nobunyulu:
• Ukusika intsimbi yekhabhoni: Kufuneka kusetyenziswe ioksijini ecocekileyo kakhulu (≥ 99.95%). Ioksijini ithatha inxaxheba kwi-exothermic reaction, inceda ekutshiseni nasekuphephuleni i-slag. Ukungacoceki ngokwaneleyo kuya kuchaphazela kakhulu umgangatho wokusika kunye nomaleko we-oxide yecandelo.

Ukusika intsimbi engagqwaliyo kunye ne-aluminium: kufuneka kusetyenziswe i-nitrogen ecocekileyo kakhulu (≥ 99.99%) okanye i-argon. Sebenzisa igesi enoxinzelelo oluphezulu ukuvuthuza isinyithi esinyibilikisiweyo ukuze kufezekiswe ukusika okungena-oxidation. Igesi engcolileyo iya kubangela i-slag ezantsi.

• Uxinzelelo lwegesi:
• Ukusika intsimbi yekhabhoni (eneoksijini): uxinzelelo akufuneki lube phezulu kakhulu (ngesiqhelo yi-0.8-2bar). Uxinzelelo olugqithisileyo luya kuyipholisa i-incision, kodwa lunciphise ukusebenza kakuhle kwempendulo yokutsha, ukwakheka kwee-burrs.
• Ukusika intsimbi engagqwaliyo/i-aluminiyamu (ene-nitrogen): Uxinzelelo kufuneka lube phezulu ngokwaneleyo (ngesiqhelo yi-10-20 bar, kuxhomekeke kubukhulu bepleyiti). Uxinzelelo olunganelanga yeyona nto ibangela ukungasebenzi kakuhle kokusika ngaphandle kwe-burr, kwaye isinyithi esinyibilikisiweyo asinakutshayelwa ngokupheleleyo.
• Imeko yeNozzle:
• Qinisekisa ukuba umlomo awonakalanga okanye awuvalwanga kukuchitheka. Umlomo ogugileyo unokubangela ukuxinana komoya.
• Jonga ukuba ububanzi bomngxuma we-nozzle buyahambelana na nobukhulu beplate kunye noxinzelelo lwegesi. Iiplate ezityebileyo zihlala zifuna ii-nozzles ezinkulu ze-orifice.
• Lungisa ubunzulu be-nozzle kunye nentloko ye-laser. Ukuphambuka kobunzulu kuya kubangela ukuba igesi ivuthuze kwaye ivelise ii-burrs kwelinye icala.

3. Jonga kwaye ugcine imeko yezixhobo

• Ukucocwa kwelensi yokukhanya: ukhuseleko lwesibuko, ukugxila kungcoliseko lwesibuko kuya kunciphisa kakhulu amandla elaser kunye nomgangatho womqadi. Jonga rhoqo kwaye ucoce okanye utshintshe iilensi.
• Umgangatho womqadi: ukulinganiswa komqadi rhoqo ukuqinisekisa ukuba indlela ye-optical ichanekile kwaye ugxininiso lujikelezile.
• Uzinzo lwezixhobo: Jonga ukuba ingaba isiporo sesikhokelo sezixhobo zomatshini kunye nenkqubo yokudlulisela izinzile na, kwaye ii-burrs ezingaqhelekanga ziya kuveliswa xa zishukunyiswa ngesantya esiphezulu.

4. Gxila kwizinto ezifundwayo ngokwazo

• Umphezulu wephepha: Qinisekisa ukuba umphezulu wephepha awunayo i-rust, ipeyinti okanye i-coating enzulu, nto leyo eya kuchaphazela ukufunxwa kwe-laser kunye nozinzo lokusika.
• Ukwakheka kwezinto kunye nomgangatho: umgangatho ophantsi okanye ukwakheka kwe-alloy engalinganiyo yepleyiti kunokubangela ukuguquguquka kwesiphumo sokusika.

Iinkxalabo ezikhethekileyo kwiingxaki zeBurr kwizixhobo ezahlukeneyo

• Ipleyiti yentsimbi yekhabhoni (ukusika ioksijini): i-burr esezantsi ikakhulu yi-slag ye-iron oxide eqinileyo nebuthathaka. Ngokuyintloko isuka kubunyulu beoksijini, indawo yokugxila, kunye nokuhambelana kwesantya samandla.
• Ipleyiti ye-aluminiyam yentsimbi engatyiwayo (ukusika i-nitrogen): ii-burrs ezisezantsi zithambile kwaye zinde kwaye zinyibilikisiwe ngentsimbi ende. Umsebenzi wokuqala kukujonga ukuba uxinzelelo lwe-nitrogen luphezulu ngokwaneleyo na, ukuba igesi icocekile na, kwaye nokuba umlomo ufanelekile na.

Iingcebiso zenkqubo yesisombululo esicwangcisiweyo

1. Rekhoda kwaye ukhuphe kwakhona:bhala phantsi uhlobo lwepleyiti ye-burr yangoku, ubukhulu, kunye nazo zonke iiparameter zenkqubo (amandla, isantya, uxinzelelo lomoya, ukugxila, uhlobo lwe-nozzle) ngokweenkcukacha.

2. Uhlengahlengiso oluguquguqukayo olunye:lungisa iparameter enye ngexesha (kucetyiswa ukuba uqale ngoxinzelelo lwegesi kunye nendawo yokugxila kuqala) ukuze kuthelekiswe uvavanyo lokusika.

3. Ukusuka ekusombululeni iingxaki ezilula ukuya kwezinzima:

• Inyathelo 1: Jonga kwaye ucoce umlomo kunye nelensi.
• Inyathelo lesi-2: Jonga ubunyulu begesi kunye noxinzelelo.
• Inyathelo lesi-3: Lungiselela indawo yokugxila.
• Inyathelo lesi-4: Lungisa ukuhambelana kwamandla kunye nesantya.
• Inyathelo lesi-5: lungisa indlela yokukhanya kunye nobunzulu besixhobo.

4. Misela ilayibrari yeparameter esemgangathweni:Nje ukuba kufumaneke iiparameter ezilungileyo zeepleyiti zeempawu ezahlukeneyo, ubukhulu kunye nezinto, ziya kurekhodwa ukuze zenze imiyalelo yokusebenza esemgangathweni.

Isishwankathelo:Eyona nto iphambili ekusombululeni ingxaki ye-laser cutting burrs "kukuqinisekisa ukuba amandla angena ngokwaneleyo, nokusebenzisana necala elizinzileyo, elicocekileyo, nelichanekileyo lokuhamba komoya ukuze kuqhushumbe ukunyibilika ngexesha". Yingxaki ecwangcisiweyo efuna ukuba umqhubi abe nomonde kwaye aphande kancinci aze aphucule ngokusebenzisa iindlela zesayensi. Ukuba onke amanyathelo angentla ajongiwe kwaye ingxaki iyaqhubeka emva kokulungiswa, kufuneka uqhagamshelane nomenzi wezixhobo ukuze ujonge ukuba amandla okukhupha i-laser okanye imo ye-beam itshintshile na.
