Akunakuphepheka ukuba kubekho iingxaki ekusebenziseni umatshini wokusika nge-laser, ngoko ke ungazisombulula njani ezi ngxaki? Jonga le mibuzo ilandelayo i-7. Ngaba ukhe wadibana nazo ngexesha lokusebenza?
1. Indlela yokusika i-punch. Naluphi na uhlobo lokusika olushushu, ngaphandle kwakwiimeko ezimbalwa apho luqala khona emaphethelweni ebhodi, ludla ngokufuna umngxuma omncinci ebhodini. Ngaphambi kokuba umatshini we-laser stamping compound usebenzise i-punch ukuze uqale uphume emngxunyeni, uze emva koko usebenzise i-laser evela kuphando lokuphuhlisa umngxuma omncinci. Kukho iindlela ezimbini ezisisiseko zokungena kwi-laser cutter ngaphandle kokusebenzisa i-perforator:
Ukugqobhoza kwe-blasting – Le nto inikwa i-laser eqhubekayo ukuze yenze i-crater embindini wento, emva koko ixutywa ngokukhawuleza kwaye isuswe ngumjelo we-oxygen coaxial kunye nomqadi we-laser. Ngokubanzi, ubungakanani bomngxuma bunxulumene nobukhulu bepleyiti. Ububanzi obuphakathi bomngxuma wokuqhumisa buyisiqingatha sobukhulu bepleyiti. Ke ngoko, ububanzi bomngxuma wokuqhumisa wepleyiti etyebileyo bukhulu kunokuba bube ngqukuva, obungafanelekanga kwiindawo ezineemfuno eziphezulu zokuchaneka komatshini. Khupha nje. Ukongeza, kuba uxinzelelo lwe-oxygen olusetyenziswa yinkampani lufana nolo xa usika, i-splash inempembelelo enkulu.
I-Pulse Punch – Isebenzisa i-laser evulwe ngamandla aphezulu ukunyibilikisa okanye ukunyibilikisa inani elincinci lezinto. Umoya okanye i-nitrogen idla ngokusetyenziswa njengegesi encedisayo ukunciphisa ukwanda kwemingxunya okubangelwa yi-oxidation exothermic. Uxinzelelo lwegesi lungaphantsi koxinzelelo lwe-oksijini ngexesha lokusika. I-pulse nganye eyenziwa yi-laser ivelisa kuphela i-jet encinci yamasuntswana, aphuhliswa ngokuqhubekayo ngobunzulu, ngoko ke sidinga ixesha lokuvumbuluka kwepleyiti etyebileyo kwimizuzwana embalwa. Nje ukuba ukuvumbuluka kugqityiwe, sika nge-oksijini endaweni yegesi encedisayo. Ububanzi obunjalo bokuvumbuluka bunempembelelo encinci kwaye umgangatho wayo wokuvumbuluka ungcono kune-blasting perforation. I-laser esetyenziselwa ukusika nge-laser akufuneki ibe namandla aphezulu okukhupha kuphela, kodwa ikwafanele ibe neempawu zexesha kunye nezendawo ze-beam, ngoko ke i-laser ye-CO2 ngokubanzi yokuhambahamba ayinakuhlangabezana neemfuno zokusika nge-laser. Ukongeza, kuyimfuneko ukuba nenkqubo yolawulo lolawulo lwendlela yegesi ethembekileyo ngakumbi ukuze kufezekiswe iintlobo ezahlukeneyo zegesi, ukutshintsha koxinzelelo lwegesi kunye nolawulo lwexesha lokubhoboza.
Ukuze kufumaneke ukusika okusemgangathweni ophezulu, kufuneka kunikwe ingqalelo kwiteknoloji yotshintsho ukusuka ekubetheni i-pulse xa i-workpiece iphumle ukuya ekusikeni okuqhubekayo ngesantya esingaguqukiyo. Ngokwethiyori, ngokuqhelekileyo kunokwenzeka ukutshintsha iimeko zobugcisa zokusika zecandelo lokukhawulezisa ishishini, njengobude be-focal, indawo ye-nozzle, uxinzelelo lwegesi, njl.njl., kodwa eneneni, akunakwenzeka ukutshintsha ngaphezu kwenye yezi meko kuba ixesha lokusebenza lifutshane kakhulu. Kwimveliso yemizi-mveliso, kunokwenzeka ukutshintsha amandla aqhelekileyo e-laser ngokutshintsha ububanzi be-pulse, i-pulse frequency, ububanzi be-pulse kunye ne-pulse frequency. Uhlalutyo lweziphumo zophando zokwenyani lubonisa ukuba indlela yesithathu inesiphumo esihle kakhulu.
2. Uhlalutyo lokuguqulwa kwenkqubo yokusika imingxuma yesitshixo. Oku kungenxa yokuba izixhobo zoomatshini baseTshayina (kuphela kwezi matshini zokusika i-laser ezinamandla aphezulu) azikwazi ukuthatha ukugqobhoza xa kusetyenzwa imingxuma yesitshixo, kodwa zisebenzisa ukugqobhoza kwe-pulse (ukubhoboza okuthambileyo), okwenza uphuhliso lwamandla e-laser kwindawo encinci yabantwana luxinene kakhulu, kwaye indawo yeshishini engacutshungulwayo iyatsha. Oku kubangela ukuguquguquka kwemingxuma, kuchaphazela umgangatho wemveliso kunye neemveliso zokucubungula. Okwangoku, kwinkqubo yokucubungula, indlela yokubetha kwe-pulse (ukubhoboza okuthambileyo) kufuneka itshintshelwe kwindlela yokubetha i-blasting (ukubhoboza okuqhelekileyo) ukusombulula le ngxaki. Kwaye kumatshini wokusika we-laser onamandla amancinci kuchasene noko, kwindlela yokucubungula imingxuma kufuneka kuthathwe iindlela ezahlukeneyo zokubetha kwe-pulse ukuze kuphuhliswe ukugqitywa komphezulu okungcono.
Isisombululo sengxaki ye-laser esincinci se-carbon steel burr, ngokwemigaqo esisiseko yomsebenzi wokusika i-laser ye-CO2 kunye noyilo lokufundisa, uhlalutyo lunokugqitywa ngokuba kukho izizathu ezilandelayo: ishishini elibangelwa yi-workpiece ukuvelisa i-burr yingxaki ephambili ebangela: indawo yokugxila ye-laser phezulu nasezantsi ayichanekanga, kufuneka kwenziwe uvavanyo lwendawo yokugxila, ngokwengqwalasela yoluntu yokulungelelanisa i-offset ngexesha; Amandla okukhupha i-laser awanelanga, kufuneka sijonge ukuba abasebenzi bejenereyitha ye-laser banokuba yinto eqhelekileyo, ukuba ayiqhelekanga, emva koko sijonge ukuba indlela yenombolo yokukhupha iqhosha lenkqubo yolawulo lwetekhnoloji ye-laser kufuneka ichaneke na, ukuze ilungiswe; Isantya sokusika sicotha kakhulu, ngoko ke kuyimfuneko ukwandisa isantya somgca kulawulo lomngcipheko wokusebenza. Ubumsulwa bokusika igesi alwanelanga, imfuneko yokuphuhlisa ukubonelela ngolawulo lokusika olusemgangathweni ophezulu kwindawo yokusebenza igesi; i-laser focus offset, imfuneko yokwenza uvavanyo lwendawo yokugxila, ngokwengqwalasela ye-offset ihlengahlengiswa rhoqo; Xa isixhobo somatshini sisebenza ixesha elide, utitshala kufuneka avale aze aqalise kwakhona.
Uhlalutyo lwe-burr olune-laser 4 lwentsimbi engagqwaliyo kunye ne-aluminium zinc plate workpiece burr, ukuvela kwezi meko, kufuneka kuqala kuqwalaselwe ukusika intsimbi enekhabhoni ephantsi xa i-burr ibangela, kodwa akunakuphepheka ukukhawulezisa isantya sokusika, kuba kunokunyusa isantya sophuhliso ngamanye amaxesha ukusika ipleyiti akugugi, le meko yokufundisa ibaluleke kakhulu ekucutshungulweni kwepleyiti ye-aluminium zinc. Ngeli xesha, kufuneka siqwalasele ukuba ingaba umlomo kufuneka utshintshwe, intshukumo engazinzile yereyile yesikhokelo kunye nezinye izinto ekufuneka zisonjululwe.
I-laser ayinqumli ngokupheleleyo imeko yohlalutyo, uhlalutyo lunokufumaneka kwiimeko ezahlukeneyo ezilandelayo, olu phuhliso luphambili lokungazinzi oluchaphazela umgangatho wokucubungula: ukukhethwa kwe-nozzle yentloko ye-laser kunye nobukhulu beplate yokucubungula akuhambisani; Isantya somgca wokusika we-laser sikhawuleza kakhulu, sidinga amandla ethu okulawula inkqubo yokusebenza ukunciphisa isantya somgca; Ukungeniswa kwe-nozzle akuvumelekanga ukuba kukhokelele kwindawo yokugxila kwe-laser. Impazamo inkulu kakhulu, kufuneka uqale kwakhona ukuze kufunyanwe idatha yokungeniswa kwe-nozzle, ingakumbi xa ukusika i-aluminium kunokwenzeka ukuba kukhokelele kuyo.
Ukusikwa kwentsimbi ekhabhoni ephantsi, ukucutshungulwa okungaqhelekanga, olu phuhliso luya kuchaphazela iindawo zomgangatho wokusika, umgangatho wemveliso. Ukuba ezinye iiparameter ziqhelekile, kufuneka kuqwalaselwe le miqathango ilandelayo: I-NOZZEL yentloko yelaser ilahlekile. Buyisela i-nozzle ngexesha. Ukuba akukho nozzle intsha yokutshintsha i-case, kufuneka yonyuse ulawulo lokusika, indawo yokusebenza, igesi idlule kuxinzelelo; Umsonto ophakathi kwe-nozzle kunye nentloko yelaser ukhululekile. Ngeli xesha, kufuneka simise ukusika ngoko nangoko, sijonge imeko yokusebenza yoqhagamshelo lwentloko yelaser, kwaye siphinde siwufake umsonto.
7. Khusela ilensi ukuze ivelise inkungu yamanzi kwinkqubo yokusika umatshini wokusika nge-laser, igesi encedisayo ibalulekile! Phakathi kwazo, ioksijini kunye ne-nitrogen zisetyenziswa kakhulu kwilizwe lethu. Ewe kona, okukhona igesi icocekile, kokukhona umgangatho wokusika uya kuba ngcono. Kukho abathengi abaninzi abafuna ukonga iindleko zokusika umoya, kodwa kusoloko kukho inkungu ekhusela ilensi kwinkqubo yokusika, umgangatho wokusika uphantsi kakhulu, kutheni?
Okokuqala, sinike lonke ulwazi oluphambili, indima yegesi encedisayo: 1. Ukuvuthuza intsalela, ukuze kufumaneke isiphumo esihle sokusika. 2. Sebenzisa igesi ukuvuthuza isinyithi esinyibilikileyo
