Ubudlelwane Phakathi Kokugxila Kokusika NgeLaser kunye NeeBurrs

Indawo ephambili ekusikeni nge-laser inobudlelwane obuthe ngqo nobuqinisekileyo kunye nokwakheka kwe-burr.Ngamafutshane, indawo egxile kuyo ichaphazela ngokuthe ngqo ukusasazwa kwamandla komqadi ngaphakathi kwezinto, ngaloo ndlela imisela umgangatho we-kerf, ukusebenza kakuhle kokugxothwa kwezinto ezinyibilikisiweyo, kunye nokuba ngaba ii-burrs ekugqibeleni ziyavela na.Ubudlelwane buchazwe ngezantsi.

Umgaqo oSisiseko: Indlela indawo egxile kuyo echaphazela ngayo inkqubo yokusika

Umgaqo wokusika nge-laser kukukhanyisa i-workpiece nge-laser beam enamandla aphezulu, nto leyo ebangela ukuba inyibilike okanye iphele ngokukhawuleza, ngelixa辅助igesi (efana neoksijini okanye initrogen) ivuthuza izinto ezinyibilikisiweyo ukuze zenze ukusika.

Ingqwalasela: Indawo apho amandla omqadi welaser egxile kakhulu kwaye ubukhulu bawo bubuncinci.

Indawo yokugxila: ibhekisa kwindawo ekuyo indawo yokugxila xa kuthelekiswa nomphezulu wento yokusebenza. Yahlulwe yangamacala amathathu:

1. Ukususa ukugxila okuhle: Indawo ephambili ibekwe ngaphezulu komphezulu wezinto zokusebenza.

2. Ukungajolisi kakuhle: Indawo ephambili ingaphantsi komphezulu wezinto zokusebenza.

3. Akukho kugxila: Indawo ephambili ikwindawo yokusebenza.

Ulwalamano oluthile phakathi kwendawo yokugxila kunye ne-burr

Uhlobo lwe-burr kukuba intsalela yokunyibilika, engakhange itshayelwe ngokupheleleyo, iyaqina kwakhona ezantsi kwe-cut. Indawo yokugxila ichaphazela i-burr ngokuchaphazela imo ye-cut kunye namandla okuhamba komoya.

1. ayijoliswanga (gxila kwisixhobo somsebenzi)

• Ukusasazwa kwamandla: Emva kokuba umqadi ungene kwizinto, uyahluka, kwaye uxinano lwamandla luyehla kancinci kancinci ukusuka phezulu ukuya ezantsi. Amandla anamandla kakhulu kumphezulu ophezulu kwaye abuthathaka kakhulu kumphezulu ongezantsi.
• Imilo yokusikwa: kulula ukwenza isisikelo esimile okwe-V esinomqolo obanzi nosezantsi omxinwa.

Isiphumo kwi-burr:

• Ngenxa yokungabikho kwamandla aneleyo ezantsi, izantsi le nto ayinakunyibilika okanye itshiswe yigesi ngokupheleleyo.
• Isantya sokuhamba kwegesi encedisayo sikhawuleziswa ezantsi, kodwa amandla okuvuthela asenokunganeli ukususa ngokupheleleyo nokuvuthuza ukunyibilika okunamandla.

Iziphumo: Kulula ukuvelisa inani elikhulu lee-burrs eziqinileyo kumphezulu ongezantsi. Le yenye yezona zinto zixhaphakileyo ezibangela ii-burrs.

2. Ukususa ukugxila okungalunganga (ukugxila ngaphantsi kwento yokusebenza)

• Ukusasazwa kwamandla; umqadi uyadibana ngaphakathi kwezinto, kwaye uxinano lwamandla lufikelela kwelona nqanaba liphezulu phakathi okanye ezantsi kwezinto.
• Imilo yokusikwa: kulula ukwenza isinqe esimile okwesigubhu esinomda ophakathi omfutshane, osezantsi nobanzi.

Isiphumo kwi-burr:

• Inzuzo kukuba amandla asezantsi awanelanga kwaye izinto zinokunyibilikiswa ngokupheleleyo.
• Nangona kunjalo, umbindi wesikhewu ngowona mkhulu, nto leyo enokubangela ukuba ukuhamba komoya kusasazeke apha kwaye kwenze buthathaka amandla okuvuthela xa ufikelela ezantsi.
• Ukuba iiparameter azihambelananga kakuhle, ukunyibilika kusenokuthi kunamathele ezantsi ngenxa yomqolo ongacocekanga.

Iziphumo: Xa kuthelekiswa ne-defocus eyakhayo, imeko ye-burr iya kuphucuka, kodwa inani elincinci le-burr ethambileyo lisenokuveliswa. Kwi-defocus etyebileyo, i-negative defocus ngamanye amaxesha isetyenziswa ukuqinisekisa ukuba izantsi liyasikwa.

3. Akukho kugxila okanye ukugxila okungcono (gxila kumphezulu wento yokusebenza okanye ubunzulu obuthile)

• Ukusasazwa kwamandla: Indawo enamandla egxininisiweyo ikwindawo yokusebenza, eyona ilungileyo ekusikweni kwepleyiti ebhityileyo. Kwiipleyiti ezixineneyo, kufuneka indawo "engcono kakhulu yokugxila", oko kukuthi, ukugxila kungena nzulu kubunzulu obuthile ngaphakathi kwezinto (umzekelo, i-1/3 yobukhulu bepleyiti) ukuze kulinganiswe amandla aphezulu nasezantsi.
• Imilo yokusika: yeyona ndlela ifanelekileyo yokusika ngokuthe nkqo, ehambelanayo.

Isiphumo kwi-burr:

• Ukusasazwa kwamandla kuyo yonke indawo yokusikwa kuyafana, kwaye izinto zinokunyibilika rhoqo nangokuzinzileyo.
• Ukunqunyulwa okulinganayo kunika indlela egudileyo yegesi encedisayo, enokuthwala amandla aneleyo e-kinetic ukuze ikhuphe kakuhle ukunyibilika ukusuka ezantsi.

Isiphumo: Le yeyona meko ilungileyo yokufumana i-burr okanye imingxunya embalwa kakhulu ye-burr. Ukunyibilika kwaphetshethwa "ngokucocekileyo" kungekho ntsalela.

Isishwankathelo kunye noHlalutyo

Ungayiqonda ngolu hlobo:

• Ayicacanga: njenge "blunt chisel", umphezulu uqinile kakhulu, kodwa ezantsi uyadinisa, unoku "khuhla" kuphela izinto, ushiye irhabaxa.
• Ukususa ukugxila okungalunganga: Njengokuqhumisa ngaphakathi kwezinto, nangona zinokuqhuma, indlela yokuphuma isenokungabi ntle kwaye iya kukhupha inkunkuma.
• Eyona nto iphambili: Njenge "scalpel ebukhali", esikwe kakuhle ukusuka phezulu ukuya ezantsi, icocekile kwaye icocekile.

Isikhokelo sokuziqhelanisa: Indlela yokulungisa ingqwalasela ngokusekelwe kwi-Glitches

Xa kusetyenzwa ngokwenene, ukuba kufunyenwe ii-burrs, kufuneka kulandelwe la manyathelo alandelayo ukujonga nokulungisa:

1. Jonga imilo ye-burr:

• Kukho ii-burrs ezininzi eziqinileyo nezineziqwenga ezantsi: kusenokwenzeka ukuba izantsi alinqunyulwanga ngenxa yokuba alikho kwi-focus (focus iphezulu kakhulu) okanye amandla aneleyo/isantya esikhawulezayo kakhulu. I-focus kufuneka ilungiswe iye ezantsi.
• Kukho inani elincinci le-burr ethambileyo, elula ukuwela efana neendevu ezantsi: isenokuba yi-negative defocus (focus iphantsi kakhulu) okanye uxinzelelo lwegesi olunganelanga/igesi engcolileyo ebangela ukuba ukunyibilika kungaphumi. Ungazama ukulungisa i-focus phezulu kwaye ujonge iiparameter zegesi.

2. Uvavanyo lokujonga nokulinganisa ingqwalasela:

• Sebenzisa isixhobo sokukhomba ugxininiso ukuze uchonge ngokuchanekileyo indawo yokugxila engu-zero.
• Kwisoftware yeparameter yokusika, uhlengahlengiso lwexabiso le-± ludla ngokwenziwa ngokusekelwe kwinqaku le-0. Yenza iiseti ezi-1 zovavanyo lokugxila (umz., ukusuka ku-+1 ukuya ku--3 ngamanyathelo angama-0.5), sika umfanekiso ofanayo, uze ujonge ukuba yeyiphi indawo enokusika okugudileyo kunye ne-least burr. Le ndawo yeyona ndawo iphambili kwizinto zangoku, ubukhulu kunye nezixhobo.

OKukho izinto eziphambili ezichaphazela iingxaki (ezimele ziqwalaselwe xa zidityaniswe)

Ukugxila akukuphela kwento ekufuneka yenziwe kwaye kufuneka kulungiswe kunye nezinye iiparameter zenkqubo:

Igesi encedisayo:

Uxinzelelo:Uxinzelelo olunganelanga alunakuwususa ngokufanelekileyo umdaka; uxinzelelo oluphezulu kakhulu lunokubangela ukungazinzi, okuya kuchaphazela uzinzo.

Ubunyulu:Ingakumbi xa usika intsimbi engagqwaliyo, kubalulekile ukusebenzisa i-nitrogen ecocekileyo kakhulu (99.99% nangaphezulu). Ioksijini eseleyo iya kwenza i-slag eyomileyo kwaye ibangele ukuba i-burrs ibe nkulu.

Isantya sokusika:Isantya sikhawuleza kakhulu, igalelo lamandla alanelanga, kwaye izinto azinqunyulwanga ngokupheleleyo, zenze ii-bottom burrs; isantya sicotha kakhulu, i-ablation egqithisileyo, ii-rough cuts, kunye nee-burrs nazo zinokwenziwa.

Amandla elaser:amandla kunye nesantya ukuze zihambelane. Amandla aphantsi kakhulu ukuba anganqumla.

Impumlo:Ukuvulwa, ukuphakama kunye nokuqina komlomo womlomo kuchaphazela ngokuthe ngqo imeko yokuhamba komoya. Ukungaqini komlomo yimbangela eqhelekileyo yomgangatho wokusika ongalinganiyo kunye neempumlo.

Izinto ngokwazo:ukwakheka kwezinto, imeko yomphezulu (njengokuba kukho umhlwa, ioyile) nazo zinempembelelo.

Indawo yokugxila yeyona parameter iphambili yohlengahlengiso lokulawula i-laser cutting burr.Indawo efanelekileyo yokugxila idala ukusika okuthe nkqo, okugudileyo kwaye ivumela igesi encedisayo ukuba ikhuphe ngokufanelekileyo ukunyibilika. Xa udibana nengxaki ye-burr, kufuneka uqale wenze uvavanyo lokugxila ngokucwangcisiweyo ukuze ufumane ukugxila okufanelekileyo, uze ulungelelanise ukulungisa ezinye iiparameter ezifana negesi kunye nesantya ukuze ufumane isiphumo esigqibeleleyo sokusika esingena-burr.
