Rarraba yankan Laser

Laser yankan za a iya yi da ko ba tare da taimakon gas don taimakawa cire narkakkar ko vapored abu. Dangane da nau'ikan iskar gas daban-daban da aka yi amfani da su, yankan Laser za a iya raba shi zuwa sassa huɗu: yankan vaporization, yankan narkewa, yankan juzu'in iskar oxygen da yanke karaya mai sarrafawa.

 

(1)Yanke vaporization

Ana amfani da katako mai ƙarfi mai ƙarfi na Laser don dumama kayan aikin, yana haifar da zafin jiki na saman kayan ya tashi da sauri kuma ya isa wurin tafasar kayan a cikin ɗan gajeren lokaci, wanda ya isa don guje wa narkewar da zafin zafi ya haifar. Kayan ya fara yin tururi, kuma wani ɓangare na kayan yana yin tururi kuma ya ɓace. Gudun fitarwa na waɗannan tururi yana da sauri sosai. Yayin da ake fitar da tururi, wani ɓangare na kayan yana busa daga ƙasan tsaga ta hanyar kwararar iskar gas a matsayin fitarwa, yana yin tsaga akan kayan. A lokacin aikin yankan vaporization, tururin yana ɗaukar narkakken barbashi da tarkacen wankewa, yana kafa ramuka. A lokacin aikin vaporization, kusan kashi 40% na kayan suna ɓacewa azaman tururi, yayin da 60% na kayan ana cire su ta hanyar iska a cikin nau'i na narkakkar digo. The vaporization zafi na abu ne kullum babba, don haka Laser vaporization yankan na bukatar babban iko da iko yawa. Wasu kayan da ba za a iya narkar da su ba, kamar itace, kayan carbon da wasu robobi, ana yanke su zuwa sifofi ta wannan hanya. Ana amfani da yankan tururin Laser galibi don yanke kayan ƙarfe na bakin ciki sosai da kayan da ba ƙarfe ba (kamar takarda, zane, itace). , roba da roba da sauransu).

 

(2) Yankewar narkewa

An narke kayan ƙarfe ta hanyar dumama tare da katako na laser. Lokacin da ƙarfin ƙarfin abin da ya faru Laser katako ya wuce wani ƙima, ciki na kayan da aka kunna wuta ya fara ƙafewa, yana samar da ramuka. Da zarar an sami irin wannan rami, yana aiki azaman baƙar fata kuma yana ɗaukar duk ƙarfin katako na abin da ya faru. Karamin ramin yana kewaye da bangon narkakkar karfe, sannan ana fesa iskar gas mara oxidizing (Ar, He, N, da sauransu) ta hanyar bututun ƙarfe coaxial tare da katako. Ƙarfin iskar gas ya sa ƙarfen ruwa da ke kewaye da ramin ya fito. Yayin da aikin aikin ke motsawa, ƙaramin rami yana motsawa tare a cikin hanyar yanke don samar da yanke. Laser katako yana ci gaba tare da gefen jagorar ƙaddamarwa, kuma narkakkar kayan ana hura shi daga ɓangarorin a ci gaba ko daɗaɗawa. Laser narkewa yankan baya bukatar cikakken vaporization na karfe, da kuma makamashi da ake bukata shi ne kawai 1/10 na vaporization yankan. Ana amfani da yankan narkewar Laser musamman don yankan wasu kayan da ba a sauƙaƙe oxidized ko karafa masu aiki ba, kamar bakin karfe, titanium, aluminum da gaminsu.

 

(3) Yanke juzu'in Oxidation

Ka'idar ta yi kama da yankan oxygen-acetylene. Yana amfani da Laser a matsayin preheating zafi tushen da oxygen ko sauran aiki gas a matsayin yankan gas. A gefe guda, iskar gas da aka busa yana jujjuya yanayin iskar oxygen tare da yankan karfe kuma ya saki babban adadin zafi na oxidation; a daya bangaren kuma, narkakkar oxide da narkake ana hura su daga yankin da za a yanke a cikin karfe. Tun lokacin da aka yi amfani da iskar oxygen a lokacin aikin yankan yana haifar da babban adadin zafi, makamashin da ake buƙata don yankan oxygen laser shine kawai 1/2 na narke yankan, kuma saurin yanke ya fi girma fiye da haka.Laser tururi yankan da narkewa yankan.

 

(4) Sarkewar karaya

Ga kayan karyewa waɗanda zafi ke lalacewa cikin sauƙi, ana amfani da katako mai ƙarfi mai ƙarfi na Laser don bincika saman abin da ke ɓarna don ƙafe wani ɗan ƙaramin rami lokacin da kayan ya yi zafi, sannan a sanya wani matsa lamba don yin aiki mai girma. gudun, controllable yankan ta Laser katako dumama. Kayan zai raba tare da ƙananan tsagi. Ka'idar wannan tsarin yanke shine cewa katako na Laser yana dumama yankin yanki na;da gaggautsa abu, haifar da babban thermal gradient da tsanani inji nakasawa a cikin yankin, haifar da samuwar fasa a cikin kayan. Muddin ana kiyaye gradient ɗin dumama uniform, katako na Laser zai iya jagorantar ƙirƙirar ƙirƙira da yaduwa a cikin kowane shugabanci da ake so.Kwayar da aka sarrafa yana amfani da rarrabuwar zafin jiki mai zurfi da aka haifar a lokacin notching na laser don haifar da damuwa na thermal na gida a cikin gaggautsa kayan don haifar da abu ya karye. tare da kananan tsagi. Ya kamata a lura cewa wannan yankan hutu mai sarrafawa bai dace da yankan sasanninta masu kaifi da santsi ba. Yanke ƙarin manyan rufaffiyar siffofi kuma ba shi da sauƙi a cimma nasara. Matsakaicin saurin raguwa mai sarrafawa yana da sauri kuma baya buƙatar iko mai yawa, in ba haka ba zai haifar da yanayin aikin aikin ya narke kuma ya lalata gefen yankan. Babban sigogin sarrafawa shine ikon laser da girman tabo.
