Kupatsanurwa kwemisoro yekutarisa yakaunganidzwa - kushandiswa

Iyomusoro unotarisa kuunganainogona kukamurwa kuita misoro yewelding ine simba guru uye iri pakati nepakati ine simba shoma zvichienderana nemamiriro ekushandisa, musiyano mukuru uri wezvinhu zvelenzi uye coating. Zviitiko zvinoratidzwa zvinonyanya kukanganiswa nekupisa (high-temperature focus drift) uye kurasikirwa nesimba. Musoro wecollimating uye focus une tembiricha yakanaka unogona kudzorwa mukati me1mm; Unoda kudarika 2mm; Kurasikirwa nesimba kunonyanya kureva kurasikirwa nesimba kunokonzerwa nelaser inopinda mumusoro wewelding kubva mumusoro weQBH uye wobva wadzivirira lenzi kubva pasi. Simba guru rinoshandurwa kuita lenzi yekupisa, iyo inowanzoda pasi pe3%, mimwe inogona kusvika 1%, uye mimwe inogona kupfuura 5%. Saka, izvi zviviri zviratidzo zvikuru zve collimating uye focus heads. Zvakanaka kuzviyera iwe pachako usati washandisa kana kukumbira mugadziri kuti ape mishumo yakakodzera kuti ave nechokwadi chekuti chigadzirwa chinosangana nezvinodiwa zvekugadzirwa kwemaindasitiri panzvimbo yacho.

Kupatsanurwa kwemisoro yekutarisa yakaunganidzwa - kupatsanurwa kwebasa

Zvichienderana nekuti ine basa rekutenderera here uye kuti igirazi rimwe chete here kana kuti maviri, inogona kukamurwa kuita musoro wecollimating nefocus, musoro wependulum imwe chete, uye musoro wependulum mbiri. Inonyanya kunanga zvinodiwa zvakasiyana zvenzvimbo, uye nzira yependulum mbiri ichave yakaoma kupfuura yependulum imwe chete.

Zvinoenderana nekuenderanasisitimu yelaser, inogona kukamurwa kuita: (1) musoro weboka remabhendi maviri (bhuruu dzvuku, fiber semiconductor, nezvimwewo), (2) musoro weboka remabhendi (single swing), uye musoro wepoindi.

(3)Musoro we welding ring welding imhando itsva yemusoro we welding inogona kugadzira matanda e laser ane simba guru kuita maumbirwo edenderedzwa kana point ring kuburikidza nekugadzira beam, ichienzanisa kugoverwa kwesimba. Inonzwa yakafanana nekushandura ma laser ane simba guru kuita mapopo echiedza chakatenderera, asi yakasiyana. Kana ichienzaniswa nemaumbirwo akatenderera, simba repakati remisoro ye point ring harina kukwana uye kugona kwavo kupinda mukati hakuna kukwana. Zvisinei, nzira iyi iri nyore yekuwana kugoverwa kwesimba re laser yakafanana nemapopo echiedza chakatenderera kuburikidza nemisoro ye point ring inogona kuwana mhedzisiro yakaderera uye yakaderera yekupwanya. Mukusungirirwa kwesimbi, ine mukana wakasiyana wegesi. Nekuda kwekuwedzera kwemapopo echiedza uye kufanana kwehuwandu hwesimba, inogona kunge iri nyore kusungirirwa kwenhema pazvinhu zvinopenya zvakanyanya (aruminiyamu, mhangura).

Lenzi yekutarisa yakabatanidzwa

Kune malenzi anoshandiswa mumasisitimu ekutumira laser, zvinhu zvavo zvinogona kukamurwa kuita mhando mbiri: zvinhu zvinotapurirana uye zvinhu zvinopenya; Lenzi inonamira uye lenzi inodzivirira inofanira kugadzirwa nezvinhu zvinopenya. Zvinodiwa: zvinhu izvi zvinofanira kunge zvine transmissivity yakanaka kune working wave band, tembiricha yepamusoro yekushanda uye low thermal expansion coefficient. Kazhinji, lenzi inonamira inofanira kugadzirwa nefused silica; Lenzi inonamira inogadzirwa nezvinhu zvinopenya, zvinowanzoitwa girazi reK9. Zvinhu zvinopenya zvinogadzirwa nekuputira firimu rakatetepa resimbi ine reflectivity yakakwira pamusoro pegirazi kana simbi, uye reflection haina dispersion. Naizvozvo, hunhu hwe optical chete hwezvinhu zvinopenya ndiko kupenya kwadzo kwemavara akasiyana echiedza. Zvinodiwa zve coating material ye optical lens ndeizvi: 1. Reflectivity yakagadzikana yechiedza; 2. High thermal conductivity; 3. High melting point; Nenzira iyi, kunyangwe paine tsvina pa coating layer, kupisa kwakanyanya hakuzokonzere kutsemuka kana kupisa.

Kusanganiswa kwe collimation ne focus kunonyanya kukanganisa saizi yenzvimbo: Saizi yenzvimbo ye laser beam chinhu chakakosha chinokanganisa mhando ye scanning welding, kunyanya saizi yenzvimbo yakatarisana pamusoro pe workpiece inokanganisa zvakananga simba re laser beam. Kana simba re scanning laser rikaramba riripo, saizi yenzvimbo diki inogona kuwana simba rakawanda, izvo zvinobatsira pakuwelda high melting point uye zvakaoma kunyungudutsa simbi. Panguva imwe chete, inogona kuwana aspect ratio yakakura uye kusangana nezvimwe zvinodiwa zve welding. Kana melting point yezvinhu zve welding yakaderera, kana kana paine mukaha pakati pemaplate maviri panguva yekuwelda, saizi yenzvimbo yakakura inowanzo sarudzwa kuti iwane mhedzisiro iri nani yekuwelda.

Kureba kwenzvimbo yekubatanidza (collimation focal length) kunowanzova pakati pe80-150mm, uye kureba kwenzvimbo yekubatanidza (focus focal length) kunowanzova pakati pe100-300mm; Izvi zvinonyanya kuenderana nedaro rekugadzirisa uye saizi yenzvimbo (simba remagetsi), pamwe nekushivirira kwenzvimbo kusvika kune weld seam gap (kana nzvimbo yacho iri diki, nzvimbo yacho ichadonhedza chiedza kana yakakura zvakanyanya, uye nzvimbo yacho kazhinji haipfuuri 30% yedhayamita yenzvimbo).

Kuyedzwa kwemusoro wekutarisa collimating usati washandiswa: kuyedzwa kwekutumira; Kuyedzwa kwekudonha kwekushisa
